    Opinion En Banc
    July 8, 2021
     Judge Torruella heard oral argument in this matter and
    participated in the semble, but he did not participate in the
    issuance of the opinion in this case.
    LYNCH, Circuit Judge.     On August 20, 2012, the Penobscot
    Nation (the "Nation") brought suit against the State of Maine and
    various state officials (the "State Defendants").              The Nation
    stated in its original complaint, later amended, that when it
    entered into an agreement with Maine to settle its land claims in
    the state, "the Nation never intended to relinquish its ownership
    rights" to a 60-mile stretch of the Penobscot River (the "River")
    known as the Main Stem and that Congress intended "that the
    Nation's    reservation   encompass    ownership    rights     within    and
    attending" the Main Stem.     The complaint sought (1) a declaratory
    judgment that the Nation had exclusive regulatory authority over
    the Main Stem; and (2) a declaratory judgment that the Nation had
    sustenance fishing rights in the Main Stem.          The United States
    intervened in support of the Nation.         Private interests, towns,
    and other political entities (the "State Intervenors") intervened
    in support of the State Defendants.
    "Penobscot Indian Reservation" (the "Reservation") is
    defined in a pair of statutes -- the Maine Implementing Act ("MIA")
    and   the   Maine   Indian   Claims    Settlement   Act      ("MICSA")    --
    collectively known as the Settlement Acts.          See Me. Rev. Stat.
    Ann. tit. 30; 
    25 U.S.C. § 1721
     et seq.         The district court, on
    cross-motions for summary judgment, issued declaratory              relief
    saying that the Reservation does not include the waters of the
    Main Stem or the submerged lands of the riverbed underneath it but
    - 3 -
    holding that the Nation has sustenance fishing rights in the Main
    Stem.   See Penobscot Nation v. Mills, 
    151 F. Supp. 3d 181
    , 222-23
    (D. Me. 2015). A divided panel of this court affirmed the district
    court's holding as to the definition of Reservation and vacated
    its holding as to the Nation's sustenance fishing rights.              The
    Nation and the United States petitioned for rehearing en banc.         We
    vacated the panel opinion and dissent and granted the petition.
    Penobscot Nation v. Frey, 
    954 F.3d 453
    , 453 (1st Cir. 2020).
    In this en banc decision, we hold that the Reservation
    does not include the waters and submerged lands constituting the
    riverbed of the Main Stem.       The plain text of the definition of
    Reservation in MIA and MICSA plainly and unambiguously includes
    certain islands in the Main Stem but not the Main Stem itself.          We
    also hold that even if there were some arguable ambiguity as to
    the language at issue, the context, history, and clear legislative
    intent require rejection of the Nation's claim. As to the Nation's
    sustenance fishing claim, we do not accept the Nation's argument
    that    its    sustenance   fishing   rights   alter   the   meaning    of
    Reservation.      We disagree that they have anything to do with the
    definition of Reservation.       Such fishing rights do not alter or
    call into question the clear definition of Reservation.        As to the
    Nation's claim that Maine has infringed those fishing rights, that
    claim is not ripe and the Nation lacks standing.

    I. Facts and Procedural History
    The Penobscot River runs through the state of Maine.
    Its East and West Branches meet at the River's Main Stem, and the
    Main Stem stretches south for 60 miles.         Within the Main Stem are
    a   number   of   islands,    including    Indian   Island,   the   Nation's
    headquarters.
    Going back centuries, various iterations of the Indian
    Nonintercourse Act, 
    25 U.S.C. § 177
    , along with a series of
    treaties and transactions between the Nation and Massachusetts1
    and the Nation and Maine, clouded title to certain land and natural
    resources in Maine.      See 
    id.
     § 1721(a)(1).        In 1980, the United
    States, Maine, the Nation, and other Indian tribes in Maine reached
    an agreement which "represent[ed] a good faith effort . . . to
    achieve a fair and just resolution of those claims which, in the
    absence of agreement, would be pursued through the courts for many
    years to the ultimate detriment of [Maine] and all its citizens,
    including the Indians."        
    Me. Rev. Stat. Ann. tit. 30, § 6202
    ; see
    
    25 U.S.C. § 1721
    (7).         To implement this agreement, Maine passed
    MIA, 
    Me. Rev. Stat. Ann. tit. 30, § 6201
     et seq., and Congress
    passed MICSA, 
    25 U.S.C. § 1721
     et seq.
    1      Present-day Maine was part of Massachusetts until 1820.
    - 5 -
    MICSA defines "Penobscot Indian Reservation" as "those
    lands as defined in [MIA]."       
    25 U.S.C. § 1722
    (i).      MIA defines the
    Reservation as:
    [T]he islands in the Penobscot River reserved to the Penobscot
    Nation by agreement with the States of Massachusetts and Maine
    consisting solely of Indian Island, also known as Old Town
    Island, and all islands in that river northward thereof that
    existed on June 29, 1818, excepting any island transferred to
    a person or entity other than a member of the Penobscot Nation
    subsequent to June 29, 1818, and prior to the effective date
    of this Act.
    
    Me. Rev. Stat. Ann. tit. 30, § 6203
    (8).2
    MIA     also   addresses     the   Nation's   sustenance   fishing
    rights, saying:
    Notwithstanding any rule or regulation promulgated by the
    [Maine Indian Tribal-State Commission] or any other law of
    the State, the members of the Passamaquoddy Tribe and the
    Penobscot Nation may take fish, within the boundaries of their
    respective   Indian   reservations,   for   their   individual
    sustenance subject to the limitations of subsection 6.
    
    Id.
     § 6207(4).3
    On    August    8,   2012,    Maine's   then-Attorney      General,
    William   Schneider,     issued   a     legal   opinion   (the   "Schneider
    Opinion") interpreting MIA and MICSA.           This opinion said that the
    River is not part of the Nation's Reservation and that Maine has
    2    The Reservation also includes a few other parcels not at
    issue here. See 
    Me. Rev. Stat. Ann. tit. 30, § 6203
    (8).
    3    Subsection 6 gives Maine's Commissioner of Inland
    Fisheries and Wildlife the right "to conduct fish and wildlife
    surveys within Indian territories." 
    Me. Rev. Stat. Ann. tit. 30, § 6207
    (6).
    - 6 -
    "exclusive regulatory jurisdiction over activities taking place on
    the River."      The Schneider Opinion did not mention § 6207(4) of
    MIA or the Nation's sustenance fishing rights.
    Twelve days later, on August 20, 2012, the Nation filed
    suit   against    the   State   Defendants.       In   its   second   amended
    complaint, it disputed the Schneider Opinion's interpretation of
    federal law.     It sought a declaratory judgment that the Nation has
    exclusive regulatory authority over the Main Stem and that the
    Nation's members have the right to take fish for their individual
    sustenance from the Main Stem which Maine has infringed.
    On February 15, 2013, the State Defendants answered the
    Nation's   complaint     and    filed   a   counterclaim     for   declaratory
    relief.    They sought a declaratory judgment that "[t]he waters of
    the main stem of the Penobscot River are not within the Penobscot
    Nation reservation."
    The State Intervenors -- a group of eighteen private
    parties, municipalities, and related entities that border the
    River and use it for discharges or other purposes -- moved to
    intervene in support of the State Defendants.           The district court
    granted this motion on June 18, 2013.          It also granted the United
    States' motion to intervene in support of the Nation on February
    4, 2014.
    In 2015, the State Defendants, the Nation, and the United
    States moved for summary judgment.          The State Intervenors filed a
    - 7 -
    motion for judgment on the pleadings.             After holding oral argument
    on these motions, the district court declared that (1) "the
    Penobscot Indian Reservation as defined in [MIA and MICSA] includes
    the islands of the Main Stem, but not the waters of the Main Stem"
    and (2) "the sustenance fishing rights provided in [MIA] allows
    the Penobscot Nation to take fish for individual sustenance in the
    entirety of the Main Stem."           Penobscot Nation, 151 F. Supp. 3d at
    222-23.4      The parties cross-appealed.
    On June 30, 2017, a divided panel affirmed the district
    court's       declaratory       judgment     regarding    the   definition    of
    "Penobscot Indian Reservation" under MIA and MICSA and vacated
    with       instructions    to   dismiss     for   want   of   jurisdiction   its
    declaratory judgment regarding the Nation's sustenance fishing
    rights under MIA.          Penobscot Nation v. Mills, 
    861 F.3d 324
    , 338
    (1st Cir. 2017).          The Nation and the United States petitioned for
    rehearing en banc.          We granted these petitions on April 8, 2020,
    and vacated the panel opinion and dissent.               Penobscot Nation, 954
    F.3d at 453.       We heard oral argument on September 22, 2020.
    II.     Analysis
    We review grants of summary judgment de novo including
    when, as here, there were cross-motions for summary judgment before
    4  On the same day, in a separate order, the district court
    granted in part and denied in part the State Intervenors' motion
    for judgment on the pleadings for the same reasons the court gave
    in its order on the other parties' summary judgment motions.

    the district court.         Signs for Jesus v. Town of Pembroke, 
    977 F.3d 93
    , 99 (1st Cir. 2020).
    A. The "Penobscot Indian Reservation" Does Not Include the Waters
    or Submerged Lands of the Main Stem.
    The State Defendants and the State Intervenors argue
    that the Reservation includes only the islands identified in
    § 6203(8) of MIA, not the water or bed of the Main Stem.                          In
    contrast, the Nation says that the Reservation includes both the
    islands referred to in § 6203(8) of MIA and the entire Main Stem,
    bank-to-bank, including its submerged lands.                 The United States
    agrees   with    the   Nation.        Alternatively,       it     says   that    the
    Reservation extends, at the very least, from the islands referenced
    in § 6203(8) to the "thread," or centerline, of the River.                      Under
    this interpretation, the Reservation would include portions of the
    River that surround each of its islands.
    1. "Penobscot Indian Reservation" is Unambiguously Defined in
    the Settlement Acts to Exclude the Main Stem.
    To    determine     whether     "Penobscot      Indian    Reservation"
    includes the River's waters and submerged lands, we must interpret
    that term as it is defined in the text of the Settlement Acts.                     We
    begin with the text itself.           See, e.g., Barnhart v. Sigmon Coal
    Co., 
    534 U.S. 438
    , 450 (2002) ("As in all statutory construction
    cases, we begin with the language of the statute."); United States
    v. Alvarez-Sanchez, 
    511 U.S. 350
    , 356 (1994) ("When interpreting
    a   statute,    we   look    first   and   foremost   to    its     text.").    When
    - 9 -
    interpreting   the   Settlement     Acts,   we   use   ordinary   tools   of
    statutory construction.      See Maine v. Johnson, 
    498 F.3d 37
    , 44–45
    (1st Cir. 2007) (treating the Settlement Acts "as a matter of
    federal law" and using "ordinary statutory construction" when
    interpreting them). As we discuss later, none of the Indian canons
    of   construction    alter   the    Settlement     Acts'   definition     of
    Reservation.
    Our "first step 'is to determine whether the language at
    issue has a plain and unambiguous meaning with regard to the
    particular dispute in the case.'"           Barnhart, 
    534 U.S. at 450
    (quoting Robinson v. Shell Oil Co., 
    519 U.S. 337
    , 340 (1997)).
    "[I]f the statutory language is unambiguous and 'the statutory
    scheme is coherent and consistent,'" Robinson, 
    519 U.S. at 340
    (quoting United States v. Ron Pair Enters., Inc., 
    489 U.S. 235
    ,
    240 (1989)), then "[o]ur inquiry must cease," id.; see Niz-Chavez
    v. Garland, 
    141 S. Ct. 1474
    , 1480 (2021); Babb v. Wilkie, 
    140 S. Ct. 1168
    , 1172 (2020); Aroostook Band of Micmacs v. Ryan, 
    484 F.3d 41
    , 50-51, 53 (1st Cir. 2007) (following MICSA's plain meaning
    when "MICSA is clear" and the "statutory scheme is a consistent
    whole on the issue in question"); see also 
    id.
     at 64 n.28.              When
    the text is unambiguous and the statutory scheme is coherent and
    consistent, we do not look to legislative history or Congressional
    intent.   Carcieri v. Salazar, 
    555 U.S. 379
    , 392 (2009) ("We need
    not consider [arguments about Congress's intent behind the Indian
    - 10 -
    Reorganization Act] because Congress' use of the word 'now' . . .
    speaks for itself and 'courts must presume that a legislature says
    in a statute what it means and means in a statute what it says
    there.'" (quoting Conn. Nat'l Bank v. Germain, 
    503 U.S. 249
    , 253–
    54 (1992))).
    In relevant part, § 6203(8) of MIA says: "'Penobscot
    Indian Reservation' means the islands in the Penobscot River
    reserved to the Penobscot Nation by agreement with [Massachusetts
    and Maine] consisting solely of Indian Island . . . and all islands
    in   that   river    northward   thereof   that   existed   on   June   29,
    1818 . . . ."       It is clear from MIA's text that the Reservation
    includes "islands."       Because "islands" is an undefined term, we
    "construe it 'in accordance with [its] ordinary meaning.'"              See
    Octane Fitness, LLC v. ICON Health & Fitness, Inc., 
    572 U.S. 545
    ,
    553 (2014) (alteration in original) (quoting Sebelius v. Cloer,
    
    569 U.S. 369
    , 376 (2013)).          Dictionaries are useful aids in
    determining a word's ordinary meaning.5       See, e.g., 
    id.
     at 553-54
    5   We interpret a statute's language in accordance with its
    ordinary meaning at the time of its enactment. See Niz-Chavez,
    141 S. Ct. at 1480; Bostock v. Clayton County, 
    140 S. Ct. 1731
    ,
    1750 (2020).    The Settlement Acts were enacted in 1980.      The
    meaning of the word "island" has not changed over the past few
    decades.     See Oxford English Dictionary (2d ed. 1989),
    https://www.oed.com/oed2/00121797 (defining "island" as "[a] piece
    of land completely surrounded by water," the same definition as in
    the most recent version of the dictionary). "Island" has had the
    same meaning for at least the past few centuries.        See Noah
    Webster, Compendious Dictionary of the English Language 166 (1806)
    (defining "island" as "land surrounded by water"); Samuel Johnson,
    - 11 -
    (citing dictionary definitions of "exceptional" to determine its
    ordinary meaning); Kellogg Brown & Root Servs., Inc. v. United
    States ex rel. Carter, 
    575 U.S. 650
    , 662 (2015) (citing dictionary
    definitions of "pending" to determine its ordinary meaning).
    An "island" is "[a] piece of land completely surrounded
    by       water."       Oxford       English       Dictionary           Online,
    https://www.oed.com/view/Entry/99986 (last visited Jan. 14, 2021)
    (first definition).        Other dictionaries confirm this ordinary
    meaning.            See       Merriam-Webster         Online     Dictionary,
    https://www.merriam-webster.com/dictionary/island              (last   visited
    Jan. 14, 2021) (first definition) ("An island is a piece of land
    that is completely surrounded by water."); Black's Law Dictionary
    (11th ed. 2019) (first and only definition) (defining "island" as
    "[a]   tract   of   land   surrounded   by    water    and   smaller   than   a
    continent").
    These definitions make two things clear.                First, an
    island is "a piece of land."        Land does not ordinarily mean land
    and water.     Indeed, land is ordinarily defined in opposition to
    water.               Oxford        English        Dictionary           Online,
    https://www.oed.com/view/Entry/105432 (last visited Jan. 14, 2021)

    earth's surface, as opposed to sea, water" (emphasis added)).
    Dictionary of the English Language (6th ed. 1785) (defining island
    as "[a] tract of land surrounded by water").
    - 12 -
    MICSA       incorporates           MIA's    definition     of     "Penobscot   Indian
    Reservation" by saying that that Reservation means "those lands as
    defined          [in    MIA],"       
    25 U.S.C. § 1722
    (i)    (emphasis    added),
    reinforcing that the Reservation consists of land only.                          MICSA
    does       not    say     "lands    and    waters"   or   "land   or   other   natural
    resources."6            Second, the piece of land constituting an island is
    "surrounded by water."                Water is important to the definition of
    "island" because the presence of water around a piece of land is
    what makes that piece of land an island.                  The surrounding water is
    not itself part of an island.                Indeed, Black's Law Dictionary goes
    on to say that the word island is used "esp[ecially]" to mean "land
    that is continually surrounded by water and not submerged except
    during abnormal circumstances."                 Black's Law Dictionary (11th ed.
    2019) (emphasis added).
    The    plain     meaning    of     "island"     is   reinforced   by
    § 6023(8)'s use of the phrase "in the Penobscot River" (emphasis
    added).          The definition references the Penobscot River to tell us
    where the islands are located and which body of water surrounds
    them.       That is what the preposition "in" means.                   Oxford English
    Dictionary             Online,     https://www.oed.com/view/Entry/92970          (last
    6  "Land or other natural resources" is a defined term in
    both MIA and MICSA that explicitly includes water. See

    visited Jan. 14, 2021) (defining "in" to mean "[o]f position or
    location").
    MIA's use of the word "solely" in the Reservation's
    definition also precludes any interpretation of § 6203(8) that
    includes   the   River's   submerged   lands   or   its   waters.    The
    Reservation includes "solely . . . Indian Island . . . and all
    islands in [the River] northward thereof . . . ."         
    Me. Rev. Stat. Ann. tit. 30, § 6203
    (8). We have already explained why an "island"
    plainly does not include its surrounding waters or submerged lands.
    Because the Reservation's definition excludes any definition that
    is not stated, see Burgess v. United States, 
    553 U.S. 124
    , 130
    (2008), because it does not say that it includes the River or its
    submerged lands, and because the Supreme Court has said that
    "'[s]olely' means 'alone,'" Husted v. A. Philip Randolph Inst.,
    
    138 S. Ct. 1833
    , 1842 (2018), and that "'[s]olely' leaves no
    leeway" for anything more, Helvering v. Sw. Consol. Corp., 
    315 U.S. 194
    , 198 (1942), the Reservation includes only the specified
    islands and not the Main Stem of the River or its submerged lands.7
    7    Because MIA's definition of Reservation clearly includes
    only the islands, we reject the United States' alternative argument
    that that the Reservation extends from the islands to the thread
    of the River. There is no support in the text for this reading.
    We also reject the Nation and United States' argument that
    state common law informs the definition of Reservation. The text
    of the Settlement Acts does not allow us to use state common law
    in interpreting the Acts' definitional provisions.

    The Nation and the United States argue that Alaska
    Pacific Fisheries v. United States, 
    248 U.S. 78
     (1918), controls
    this case. More than a century ago, in Alaska Pacific, the Supreme
    Court interpreted the phrase "the body of lands known as Annette
    Islands, situated in Alexander Archipelago in Southeastern Alaska"
    used in an 1891 statute establishing an Indian reservation.            
    Id. at 86
     (quoting Act of March 3, 1891, ch. 561, § 15, 
    26 Stat. 1095
    ,
    1101).      It held that "the geographical name was used, as is
    sometimes    done,   in   a   sense   embracing    the   intervening   and
    surrounding waters as well as the upland -- in other words, as
    descriptive of the area comprising the islands."          
    Id. at 89
    .    In
    reaching this conclusion, the Court relied on the statute's plain
    text, legislative history, and the Indian canon of construction
    that "statutes passed for the benefit of dependent Indian tribes
    or communities are to be liberally construed, doubtful expressions
    being resolved in favor of the Indians."          
    Id.
    The Court found that the phrase "body of lands known as
    the Annette Islands" at issue in Alaska Pacific was ambiguous and
    had no plain meaning.     See Amoco Prod. Co. v. Village of Gambell,
    
    480 U.S. 531
    , 548 n.14 (1987) ("There is no plain meaning to 'the
    body of lands' of an island group." (citing Alaska Pacific, 
    248 U.S. at 89
    )).    As the Court explained in a later case, "body of
    lands" is ambiguous because it has no precise geographic meaning.
    
    Id.
     (stating that "body of lands" "did not have [a] precise
    - 15 -
    geographic/political meaning[] which would have been commonly
    understood[] without further inquiry" (citing Alaska Pacific, 
    248 U.S. at 89
    )).     It was unclear if the water between the lands was
    part of the "body."    To resolve the ambiguity, the Court relied on
    legislative history.    Alaska Pacific, 
    248 U.S. at 89
    .
    There is no ambiguity here, and so for that and other
    reasons Alaska Pacific does not help the Nation, the United States,
    or the dissent.     A recent ruling by the Supreme Court involving
    the boundaries of an Indian reservation has confirmed that reliance
    on legislative history is only appropriate when a statute is
    ambiguous.   McGirt v. Oklahoma, 
    140 S. Ct. 2452
    , 2469 (2020)
    ("There is no need to consult extratextual sources when the meaning
    of a statute's terms is clear.").    Similarly, Alaska Pacific only
    relied on an Indian canon that resolves "doubtful expressions" in
    favor of Indian tribes because there was an ambiguity.     
    248 U.S. at 89
    .   When it was decided in 1918, Alaska Pacific did not
    establish a special rule of construction when tribes' claims
    involve water rights.     It certainly did not establish a special
    rule of construction meant to govern a different statute enacted
    for a different purpose a century later.      Indeed, the Court has
    repeatedly recognized that in its past cases "address[ing] the
    unique circumstances of Alaska and its indigenous population,"
    "[t]he 'simple truth' . . . is that 'Alaska is often the exception,
    not the rule.'"    Yellen v. Confederated Tribes of Chehalis Rsrv.,
    - 16 -
    No. 20-543, 
    2021 WL 2599432
    , at *3 (U.S. June 25, 2021) (quoting
    Sturgeon v. Frost, 
    577 U.S. 424
    , 440 (2016)).                The general rule
    applicable   to    statutes   is,    as      the   Supreme    Court   recently
    reinforced, that the "inquiry into the meaning of [a] statute's
    text ceases when 'the statutory language is unambiguous and the
    statutory scheme is coherent and consistent.'"               Matal v. Tam, 
    137 S. Ct. 1744
    , 1756 (2017) (quoting Barnhart, 
    534 U.S. at 450
    ).
    As we have explained, the definition of Reservation in
    the Settlement Acts is not ambiguous.              It does not refer to a
    nebulous "body of lands."           Instead, it says the Reservation
    consists "solely" of islands "in the Penobscot River."                
    Me. Rev. Stat. Ann. tit. 30, § 6203
    (8).        The word "islands" has a plain and
    precise geographic meaning, "solely" tells us that the Reservation
    includes nothing else, and the phrase "in the Penobscot River"
    specifies where the islands are.          The fact that the Supreme Court
    interpreted different language in a different statute that was not
    a settlement act to reach a different result cannot be used to
    create ambiguity in this statute.          See McGirt, 140 S. Ct. at 2469
    ("The only role [extratextual sources] can properly play is to
    help 'clear up . . . not create' ambiguity about a statute's
    original meaning." (quoting Milner v. Dep't of Navy, 
    562 U.S. 562
    ,
    574 (2011))).     For similar reasons, the Nation and United States'

    The Nation and the United States next argue that our
    holding   in   Maine   v.   Johnson   conflicts    with   our   reading   of
    Reservation.     Johnson     addressed   whether   the    Settlement   Acts
    8    The dissent relies on Hynes to muddy the waters. There,
    the Supreme Court interpreted the statutory phrase "any other
    public lands which are actually occupied by Indians or Eskimos
    within [the Territory of Alaska]" to include coastal waters for
    purposes of authorizing the Secretary of the Interior to designate
    such territory as part of an Indian reservation.

    16. It considered a number of extratextual factors in reaching
    that conclusion.   
    Id.
     As the Court later clarified, it did so
    because that statutory phrase "did not have [a] precise
    geographic/political meaning[] which would have been commonly
    understood, without further inquiry, to exclude the waters," nor
    did the narrower phrase "'public lands,' in and of itself, ha[ve]
    a precise meaning." Amoco Prod., 
    480 U.S. at
    548 nn.14-15. Hynes
    does nothing to dispel the fact that the term "lands" in isolation
    ordinarily excludes water, see, e.g., Hynes, 
    337 U.S. at 102
    (referring to the "lands or waters" of a reservation), and that
    additional definitional or qualifying language is required for it
    to encompass water. The term "lands" in the context of MICSA's
    definition of the Reservation stands alone, and its incorporation
    by reference of MIA's definition of the Reservation as consisting
    "solely" of specified islands "in" water indicates that it should
    retain its ordinary meaning.
    9    In Choctaw Nation, the language at issue was very
    different from the language in the definition of Reservation. The
    Court found the language ambiguous because it granted the Choctaw
    Nation land "up the Arkansas [River]" and "down the Arkansas
    [River]." 
    397 U.S. at 631
    . Additionally, unlike here, the Court
    was interpreting a treaty and applied the canon of construction

    understood them."

    .       The court held that they
    did not.     
    Id. at 45-47
    .       In doing so, it explicitly refused to
    decide the boundaries of the tribes' territories.                   See 
    id.
     at 40
    n.3 ("The territorial boundaries are disputed but, for purposes of
    this case, we assume (without deciding) that each of the disputed
    discharge points lies within the tribes' territories."); 
    id. at 45
    (describing "navigable waters within what we assume to be tribal
    land").     The Nation and United States point to dicta in Johnson
    where the court said "the facilities appear . . . to discharge
    onto reservation waters retained by the tribes under the Settlement
    Act."      But   in    citing   this     dicta,    they    ellipt      the    court's
    parenthetical explaining that it was not resolving any boundary
    disputes.

     ("[T]he facilities appear (even assuming the
    tribes' boundary claims) to discharge onto reservation waters

    plain   meaning       of   Reservation    and     does    not   bind    us.       See

    The Nation, United States, and dissent also say that
    Maine's arguments to us in its brief in Johnson are a concession
    that the Nation's Reservation contains the Main Stem in its
    entirety.    Not so, either on a reading of that brief or under the
    law.   In a recent dispute related to the boundaries of an Indian
    reservation, the Supreme Court confirmed that a party's prior
    litigation position on a reservation's boundaries in a single case
    does not concede the point in future cases.            See McGirt, 140 S.
    Ct. at 2473 n.14 (rejecting the dissent's reliance on "a single
    instance     in   which   the    Creek    Nation   disclaimed      reservation
    boundaries    for   purposes     of   litigation");   see   also    Alt.   Sys.
    Concepts, Inc. v. Synopsys, Inc., 
    374 F.3d 23
    , 33 (1st Cir. 2004)
    (outlining the doctrine of judicial estoppel, which requires that
    "the estopping position and the estopped position . . . be directly
    inconsistent" and that "the responsible party . . . have succeeded
    in persuading a court to accept its prior position").                      In a
    footnote of a brief that it submitted in Johnson, Maine stated
    that it was its "position that the Penobscot Reservation includes
    those islands in the main stem above and including Indian Island
    that have not otherwise been transferred, as well as the usual
    accompanying      riparian      rights   that   likewise    have    not    been
    transferred, and that those riparian rights are subject to state
    regulation."      Brief of State of Maine as Intervenor-Respondent at
    3 n.2, 
    498 F.3d 37
     (Nos. 04-1363, 04-1375).            It went no further
    - 20 -
    than this.     Maine did not explain what it understood to be the
    sort of riparian rights that would "usual[ly] accompany[]" an
    island reservation, and it is unclear whether it was asserting
    that none of those rights had "been transferred" or that the
    Reservation    retained   only   those    rights   that   had   not   been
    transferred.    Nor did it explain to what extent those rights were
    "subject to state regulation."     In any case, the Johnson court did
    not adopt any version of Maine's statement and that issue was not
    before it.    Maine's past arguments in Johnson cannot override the
    Settlement Acts' plain text.
    2. The Definition of Reservation Is Not Altered by the
    Limitation of the Reservation to Islands as Earlier
    Described in Historic Treaties Between the Nation and
    Massachusetts and Maine.
    The Nation, United States, and dissent argue that, when
    construing the definition of Reservation in the Settlement Acts,
    we must look to the Nation's past treaties with Massachusetts and
    Maine.    They say that because § 6203(8) describes the islands in
    the Reservation as those "reserved to the Penobscot Nation by
    agreement with the States of Massachusetts and Maine," 
    Me. Rev. Stat. Ann. tit. 30, § 6203
    (8), these past treaties govern what
    "island" means in the Settlement Acts.10      They argue that "island"
    10   The 1796 treaty between the Nation and Massachusetts
    says that the Nation gave up their rights to "all the lands on
    both sides of the River Penobscot" but reserved "all the Islands
    in said River, above Old Town, including said Old Town island."
    The 1818 treaty reaffirmed the Nation's 1796 surrender of land on
    - 21 -
    does not carry its ordinary meaning but instead is a term of art
    that means "anything reserved to the Nation by the 1796 and 1818
    treaties."   They make the disputed assertion that the Nation never
    gave up any rights to the River in those treaties and from this
    they conclude that the term Reservation must include the River.
    To support this reading of § 6203(8), the Nation cites § 1723 of
    MICSA, which it says extinguished the Nation's aboriginal title
    only to lands it transferred, and the House and Senate Reports,
    which say that "[t]he Penobscot Nation will retain as reservations
    those lands and natural resources which were reserved to them in
    their treaties with Massachusetts and not subsequently transferred
    by them."    S. Rep. No. 96-957 at 18 ("Senate Report"); H.R. Rep.
    No. 96-1353 at 18 ("House Report").
    MIA's reference to these treaties does not alter the
    plain meaning of "islands" and creates no ambiguity.    The phrase
    "islands in the Penobscot River reserved to the Penobscot Nation
    by agreement with the States of Massachusetts and Maine" is not a
    term of art.    See Confederated Tribes of Chehalis Rsrv., 
    2021 WL 2599432
    , at *7 (refusing to "discard the plain meaning of [a
    statute's] 'Indian tribe' definition in favor of a term-of-art
    both sides of the River and the reservation of certain islands in
    the River to the Nation.        It also gave the citizens of
    Massachusetts "a right to pass and repass any of the rivers,
    streams, and ponds which run through any of the lands hereby
    reserved."
    - 22 -
    construction" because the statutory context did not support such
    a reading).      MIA mentions the treaties to identify which islands
    in the River are part of the Reservation. The Reservation includes
    the "islands in the Penobscot River," minus any islands that were
    not   "reserved     to    the   Penobscot     Nation     by   agreement     with
    [Massachusetts      and    Maine]."         
    Me. Rev. Stat. Ann. tit. 30, § 6203
    (8).     Within this subset of islands, MIA further limits
    the Reservation: it "consist[s] solely of Indian Island" and the
    islands north of Indian Island "that existed on June 29, 1818,"
    minus any island "transferred to a person or entity other than a
    member of the Penobscot Nation subsequent to June 29, 1818, and
    prior to the effective date of this Act."            
    Id.
    The     dissent      states   that     this     interpretation     of
    Reservation treats the phrase "reserved to the Penobscot Nation by
    agreement" "as if it were superfluous."                  Not so.   The phrase
    "reserved to the Penobscot Nation by agreement" serves an important
    purpose: it makes the definition of Reservation consistent with
    § 1723 of MICSA.     If the phrase "reserved . . . by agreement" were
    removed from the definition, then the Reservation would plainly
    include any islands in the River north of Indian Island that were
    transferred before June 29, 1818 but never reserved by agreement.11
    11  This is so because § 6203(8) only excludes islands
    transferred "subsequent to June 29, 1818" (emphasis added), the
    date of a treaty between the Nation and Massachusetts, from the
    Reservation. Without the reference to islands "reserved . . . by
    - 23 -
    Such a definition would conflict with 
    25 U.S.C. § 1723
    , which
    ratified all transfers the Nation made before December 1, 1873.
    See Van Buren v. United States, 
    141 S. Ct. 1648
    , 1656 (2021)
    (holding that statutory text is not superfluous where removing it
    changes a statute's meaning).
    The dissent's interpretation of § 6203(8), independent
    of its flawed account of the history and meaning of the treaties,
    is     inconsistent      with   the    applicable       rules     of    statutory
    interpretation.          Its    reading   of    Reservation       would     render
    superfluous other language in the definition.              If the dissent were
    correct that the Nation reserved "all the islands in the Penobscot
    [R]iver above Oldtown and including . . . Oldtown [I]sland" in its
    1818    treaty   with    Massachusetts    and    that    the    Settlement    Acts
    intended to import this meaning into the definition, then the
    statutory phrase "consisting solely of Indian Island, also known
    as Old Town Island, and all islands in that river northward
    thereof" would serve no purpose.               The canon against surplusage
    counsels against such an interpretation.12              See City of Chicago v.
    agreement,"      the    definition    would    say   nothing    about     pre-1818
    transfers.
    12 Removing the superfluous language, the statutory
    definition would read: "'Penobscot Indian Reservation' means the
    islands in the Penobscot River reserved to the Penobscot Nation by
    agreement with the States of Massachusetts and Maine that existed
    on June 29, 1818 . . . ." Even after almost all of the "consisting"
    phrase is removed, the definition would still make clear that post-
    1818 islands are not part of the Reservation.
    - 24 -
    Fulton, 
    141 S. Ct. 585
    , 591 (2021) ("The canon against surplusage
    is   strongest   when   an   interpretation   would   render   superfluous
    another part of the same statutory scheme." (quoting Yates v.
    United States, 
    574 U.S. 528
    , 543 (2015))).
    The dissent's proposed reading would also make other
    parts of § 6203(8) inoperative.         The definition says that the
    Reservation includes "all islands" north of Indian Island "that
    existed on June 29, 1818."          If, as the dissent posits, the
    Settlement Acts intended the Reservation to include the entire
    Main Stem by referencing the treaties, then anything in the Main
    Stem north of Indian Island would be read to be part of the
    Reservation.     Under the dissent's reading, this would be true
    regardless of whether the land was submerged on June 29, 1818.
    The phrase "that existed on June 29, 1818" would be redundant and
    would have no meaning under the dissent's interpretation. Further,
    the inclusion of the phrase reinforces that "islands" means only
    the uplands.
    In attempt to avoid these evident problems with its
    interpretation, the dissent proposes that the "consisting solely
    of . . ." phrase was included to clarify that the Reservation
    includes the entire Main Stem, including Indian Island and all of
    the islands north of Indian Island, minus any uplands in the river
    that did not exist on June 29, 1818.       This proposed reading by the
    dissent is impermissible for a different reason: it requires the
    - 25 -
    word "islands" to have two different meanings within the definition
    of   Reservation.   Under   the    dissent's   proposed   reading,   when
    "islands" is used in the phrase "islands in the Penobscot River,"
    it must mean "an area that includes waters."      Then, when "islands"
    is used later in the same sentence in the nearly identical phrase
    "all islands in that river," it must mean "uplands alone."13         That
    proposed reading is flatly at odds with the text.         It also would
    violate the "normal rule of statutory construction that 'identical
    words used in different parts of the same act are intended to have
    the same meaning.'"    See Sullivan v. Stroop, 
    496 U.S. 478
    , 484
    (1990) (quoting Sorenson v. Sec'y of Treasury, 
    475 U.S. 851
    , 860
    (1986)).   This rule is "surely at its most vigorous when a term is
    repeated within a given sentence."         Brown v. Gardner,

    , 118 (1994) (stating that, given the "presumption that a given
    term is used to mean the same thing throughout a statute," it would
    be "virtually impossible" to read a statute in a way that would

    Our reading of § 6203(8)'s reference to the treaties is
    also consistent with how MIA defines the Passamaquoddy Indian
    Reservation.      That definition similarly begins by referencing a
    treaty, saying that the Passamaquoddy Indian Reservation "means
    those lands reserved to the Passamaquoddy Tribe by agreement with
    the State of Massachusetts dated September 19, 1794."                     
    Me. Rev. Stat. Ann. tit. 30, § 6203
    (5).              It then says that "[f]or the
    purposes    of    this    subsection,       the   lands        reserved    to   the
    Passamaquoddy Tribe by the aforesaid agreement shall be limited
    to" various islands and parcels.            
    Id.
     (emphasis added).          Like in
    the definition of Penobscot Indian Reservation, the agreement is
    referenced to limit which islands the reservation includes.                     Also
    like in the definition of Penobscot Indian Reservation, the islands
    referenced in the treaty are then further restricted to mean less
    than what the treaty reserved for the tribe.                   The definition of
    Reservation      accomplishes    this   restriction       by     using    the   word
    "solely," while the definition of Passamaquoddy Indian Reservation
    does so by saying "shall be limited to." The fact that the drafters
    clearly intended the Passamaquoddy Indian Reservation to cover
    less than what was reserved to the Passamaquoddy Tribe in its
    agreement with Massachusetts undercuts the dissent's theory that,
    - 27 -
    when defining Penobscot Indian Reservation, "the drafters of the
    Settlement Acts intended in defining the 'Reservation' to preserve
    what had been 'reserved . . . by agreement' prior to the Acts'
    passage."
    There    is   no    plausible    argument       that    the    historic
    treaties referenced in § 6203(8) govern the interpretation of the
    Settlement     Acts.        The   treaties    no   longer      have    any    meaning
    independent of the Settlement Acts, and MICSA is clear that Maine
    no   longer    has    any   responsibilities       to   the    Nation       under    the
    treaties. 
    25 U.S.C. § 1731
     ("[This Act] shall constitute a general
    discharge and release of all obligations of the State of Maine

    any Indian nation.").
    Even if the treaties could arguably be thought to induce
    any ambiguity in § 6203(8), we reach the same conclusion.                           When
    the text of a statute is ambiguous, we resolve the ambiguity by
    looking to other evidence of the drafters' intent.                      Carnero v.

    345–46.                Here, the legislative history,
    context, and purpose of the Settlement Acts show that the drafters
    never intended the Reservation to include the River itself.
    - 28 -
    Before the Settlement Acts were passed, Massachusetts,
    then Maine, had exercised regulatory authority over the River for
    more than a century.     Massachusetts regulated the River before its
    1818 treaty with the Nation.       See 1810 Mass. Laws ch. LXXXVIII
    (outlining penalties for obstructing the River or taking fish from
    it outside of approved times) ; 1813 Mass. Laws ch. CXLIV (same);
    1816 Mass. Laws ch. XCIX (providing for the appointment of fish
    wardens   for   the   River).   After   the   1818   treaty,    once   Maine
    separated from Massachusetts and became a state in 1820, it
    regulated the River in Massachusetts's stead.           See 1843 Me. Laws
    ch. 25 (providing for the appointment of fish wardens to supervise
    fisheries in the River).
    Massachusetts and Maine also conveyed parcels along the
    Main Stem, including adjacent submerged lands, to municipalities
    and private parties in publicly recorded deeds.            These entities
    relied on the title given to them by Maine and Massachusetts.          They
    used the Main Stem and built on its submerged lands.           For example,
    several dams were constructed in and adjacent to the Main Stem
    beginning in the 19th and 20th centuries.            See, e.g., Penobscot
    Chem. Fibre Co., 30 F.P.C. 1465, 1465–66 (1963) (describing the
    Great Works Dam, which was "built prior to 1900"); Bangor Hydro-
    Elec. Co., 42 F.P.C. 1302, 1302 (1969) (describing two dams in the
    Main Stem which were acquired in 1925).       The Nation admits that it
    did not execute leases or grant any interest in connection with
    - 29 -
    any of these dams.   As amended in 1988, § 6203(8) even mentions
    the owner of some of these dams, Bangor-Pacific Hydro Associates.
    It says that the Reservation includes certain "parcels of land
    that have been or may be acquired by [the Nation] from [Bangor-
    Pacific] as compensation for flowage of reservation lands by the
    West Enfield dam." Notably, the compensation is only for flowage.14
    It is not for building a dam on the submerged lands of the Main
    Stem.
    The Settlement Acts' stated intention was to resolve
    outstanding   disputes   among   the      Nation,   Maine,   and   parties
    represented by the State Intervenors.         The Settlement Acts were
    passed after the Nation, along with two other tribes, claimed title
    to two-thirds of Maine, an area "on which more than 250,000 private
    citizens now reside."    Senate Report at 11; House Report at 11.
    In response to these claims, President Carter appointed retired
    Georgia Supreme Court Justice William B. Gunter to recommend a
    settlement.   Senate Report at 13.     Gunter's recommendation to the
    President, which served as the basis for the Settlement Acts and
    which is included in the Senate Report, explained that the Nation's
    claims had caused "economic stagnation within the claims area" and
    14   "Flowage" is "an overflowing onto adjacent land" or "a
    body of water formed by overflowing or damming."      See Merriam-
    Webster       Online       Dictionary,        https://www.merriam-

    had resulted in "a slow-down or cessation of economic activity
    because property cannot be sold, mortgages cannot be acquired,
    title insurance becomes unavailable, and bond issues are placed in
    jeopardy."    Id. at 55.       Justice Gunter wrote that "[w]ere it not
    for this adverse economic result, these cases could take their
    normal course through the courts, and there would be no reason or
    necessity" for President Carter to take any action to facilitate
    a settlement.       Id.   He ultimately recommended a settlement with
    terms similar to those in MIA and MICSA.            Id. at 56.     However,
    emphasizing the need to address the economic consequences of the
    Nation's land claims and settle the land disputes, he wrote that
    "Congress should immediately extinguish all aboriginal title, if
    any, to all lands within the claims area except that held in the
    public ownership by the State of Maine" if a settlement could not
    be reached.       Id. at 57.
    The    text   of   MICSA   explicitly   incorporates   Justice
    Gunter's concern about avoiding litigation and clarifying title to
    land in Maine.       It states MICSA's purpose is to "to remove the
    cloud on titles to land in [Maine] resulting from Indian Claims"
    and "to clarify the status of other land and natural resources in
    [Maine]."     
    25 U.S.C. § 1721
    (b)(1)-(2).      Other parts of the House
    and Senate Reports on MICSA further support the idea that the
    Settlement Acts were passed to avoid litigation in which "the court
    would be required to decide questions of fact concerning events
    - 31 -
    which began before this country was founded."     Senate Report at
    13; House Report at 12-14.
    A key provision of the Settlement Acts, § 1723 of MICSA,
    helped Congress achieve this purpose.    Through § 1723, Congress
    retroactively ratified "any transfer of land or natural resources
    located anywhere within the State of Maine" made by any Indian
    tribe, including the Nation.   
    25 U.S.C. § 1723
    (a)(1).   "Transfer"
    is defined extremely broadly15 and includes "any act, event, or
    circumstance that resulted in a change of title to, possession of,
    dominion over, or control of land or natural resources."        
    Id.
    § 1722(n).   The Settlement Acts also extinguished aboriginal title
    to any land or natural resources the Nation transferred and barred
    the Nation from making claims "based on any interest in or right
    involving such land or natural resources." Id. § 1723(c). Through
    this provision, Congress intended to extinguish all of the Nation's
    land claims in Maine.    See House Report at 18 ("[Section 1723]
    provides for the extinguishment of the land claims of the . . .
    the Penobscot Nation . . . in the State of Maine.").
    Maine and the Nation "each . . . benefitted from the
    settlement."   Akins v. Penobscot Nation, 
    130 F.3d 482
    , 484 (1st
    15   The Senate Report says that the word "transfer" covers
    "all conceivable events and circumstances under which title,
    possession, dominion, or control of land or natural resources can
    pass from one person or group of persons to another person or group
    of persons." Senate Report at 21.
    - 32 -
    Cir. 1997).     Indeed, the Nation benefited greatly.             It largely
    received "the powers of a municipality under Maine law."             Id.; see
    
    Me. Rev. Stat. Ann. tit. 30, § 6206
    .           The settlement "confirmed
    [the Nation's] title to designated reservation lands, memorialized
    federal recognition of its tribal status, and opened the floodgate
    for the influx of millions of dollars in federal subsidies."

    130 F.3d at 484
     (quoting Passamaquoddy Tribe v. Maine, 
    75 F.3d 784
    , 787 (1st Cir. 1996) (alteration in original)).              It also
    established two multi-million-dollar trusts for the Nation: (1) a
    $26.8 million trust to buy land and (2) a $13.5 million trust whose
    income is paid quarterly to the Nation.            See 
    25 U.S.C. § 1724

    461 A.2d 478
    , 487 n.6 (Me. 1983)
    (describing the trusts).       Indeed, the Native American Rights Fund,
    which represented the Nation in its land claim cases before the
    Settlement Acts were passed, said shortly after the settlement
    that "[t]he Maine settlement is far and away the greatest Indian
    victory of its kind in the history of the United States."                  See
    Penobscot Nation, 151 F. Supp. 3d at 196.
    Discounting    the      history    of    the   Settlement      Acts
    themselves,    the   dissent     tells   a   one-sided    story   about   the
    importance of the River to the Nation, details the various treaties
    the   Nation   entered   into,    and    speculates    about   the   Nation's
    understanding of those treaties and how they must have reserved
    the River for the Nation.       It ends its history in the early 1800s,
    - 33 -
    saying that it is this history that "formed the backdrop for the
    Settlement Acts."   It also relies on "post-enactment history of
    the Settlement Acts" to reinforce its understanding, something the
    Supreme Court has specifically counseled against.       See McGirt, 140
    S. Ct. at 2452 ("[E]vidence of the subsequent treatment of the
    disputed land . . . has 'limited interpretive value.'" (quoting
    Nebraska v. Parker, 
    136 S. Ct. 1072
    , 1082 (2016))); see also South
    Dakota v. Yankton Sioux Tribe, 
    522 U.S. 329
    , 356 (1998) (calling
    post-enactment history the "least compelling" form of evidence).
    It insists without textual support that the Settlement Acts "were
    intended in significant part to make up for the fact that the
    Nation had entered into . . . treaties . . . without . . . federal
    authorization" in violation of the Nonintercourse Act.
    The   dissent's   view   of   history   is   disputed,16   and,
    regardless, beside the point.      The record does not support the
    contention that the drafters were motivated by anything other than
    their stated purpose of "remov[ing] the cloud on the titles to
    land in the State of Maine resulting from Indian claims."              
    25 U.S.C. § 1721
    (b)(1).   They removed this cloud and settled all of
    the Nation's claims by giving the Nation certain land, power,
    recognition, and money. As we have recounted, the Settlement Acts'
    16   For example, the State Intervenors argue that the
    Nation's aboriginal title to the River was extinguished by the
    Nation's 1713 treaty with Great Britain, the Treaty of Portsmouth.
    - 34 -
    drafters wanted to avoid expensive, protracted litigation about
    aboriginal title.       They did not want courts to decide if, when, or
    how the Nation's aboriginal title was extinguished by interpreting
    centuries-old documents.       And, as they stated explicitly, they did
    not want the Nation's claims of aboriginal title rooted in these
    treaties   to   muddy    otherwise-valid    title   to   lands   or   natural
    resources in Maine.
    Interpreting § 6203(8)'s reference to the treaties as a
    resurrection of the Nation's claim to aboriginal title contravenes
    all of these purposes.        The dissent would have us undo MIA and
    MICSA's settlement of all ownership disputes.             But "[w]e cannot
    interpret . . . statutes to negate their own stated purposes."
    King v. Burwell, 
    576 U.S. 473
    , 493 (2015) (quoting N.Y. State Dep't
    of Soc. Servs. v. Dublino, 
    413 U.S. 405
    , 419–20 (1973)).               It is
    implausible that the drafters intended to give the Nation exclusive
    control of the Main Stem -- something it did not have in 1980 --
    through a reference (which serves a different purpose) to long-
    since-replaced historic treaties.17        This is especially so when the
    17   The legislative history of the Settlement Acts provides
    even more evidence that the Reservation does not include the River.
    In background information provided to the House Committee on
    Interior and Insular Affairs, the Reservation was described as "a
    4,000-acre reservation on a hundred islands in the Penobscot
    River." Settlement of Indian Land Claims in the State of Maine:
    Hearing on H.R. 7919 Before the Comm. on Interior and Insular
    Affairs, 96th Cong. 159 (1980) (background on H.R. 7919). If the
    Reservation included the entirety of the Main Stem, bank-to-bank,
    it would have had a surface area of approximate 13,760 acres.
    - 35 -
    Settlement Acts released Maine from any obligation under those
    same treaties, abolished the Nation's aboriginal title to anything
    it ever voluntarily or involuntarily transferred, and purported to
    settle all of the Nation's land and natural resource claims against
    Maine and private parties.
    Further, it is noteworthy that the Settlement Acts' text
    and legislative history clearly indicate that the drafters did not
    intend to give control of the Main Stem to the Nation.            Doing so
    would have been an enormous change.          The River is an important
    water     artery   that   Maine   (and   Massachusetts   before   it)   has
    controlled for centuries.18       When the Settlement Acts were drafted
    and passed, the Nation's claim to the River and other lands or
    natural resources in Maine was speculative.         If the drafters had
    intended to shift Maine's longstanding ownership and control of
    the Main Stem to the Nation, we would expect to see language in
    the Settlement Acts' text or legislative history demonstrating
    this intent and addressing the consequences of doing so.                See,
    e.g., 
    Me. Rev. Stat. Ann. tit. 30, § 6207
    (3) (explicitly providing
    for "an orderly transfer of regulatory authority" between Maine
    18   As the State Intervenors put it, "it defies credulity
    that in 1980, after almost two hundred years of State control, the
    Settlement Acts would place the largest river running through the
    heart of the state, used by myriad mills, municipalities, and the
    public, within the boundaries of the Reservation, to be regulated,
    for the first time since colonists arrived, by the Nation."

    and the Maine Indian Tribal-State Commission over specified bodies
    of water); 
    id.
     § 6207(6) (describing procedures by which Maine's
    Commissioner of Inland Fisheries and Wildlife may intervene in the
    event that "a tribal ordinance or commission regulation . . .
    adversely affect[s] or is likely to adversely affect the stock of
    any fish or wildlife on lands or waters outside the boundaries of
    land or waters subject to [tribal or commission authority]").            But
    we see none.     It is improbable that, without addressing the issue,
    the drafters intended to carry out such a massive change in
    ownership and control over the Main Stem.
    The dissent tries to limit the practical consequences of
    its argument by saying that "the Nation has not . . . claimed a
    right to exclude non-tribal members from any of the waters of the
    Penobscot River or to control passage in those waters."            It calls
    the   State    Defendants'   and    State    Intervenors'   arguments   about
    ownership a "distraction."         The idea that the Nation only seeks to
    assert limited ownership rights in the River is purely speculative
    and contrary to the record. In its original complaint,19 the Nation
    19  These statements do not appear in the Nation's second
    amended complaint, and the Nation's brief to the original panel
    says that the second amended complaint "is narrowly drawn to
    address the only live controversy." However, in that same brief,
    the Nation argues that "it retains aboriginal title to the
    submerged lands of the Main Stem." It describes aboriginal title
    as "not identical to ownership" but, quoting Oneida County v.
    Oneida Indian Nation of New York, 
    470 U.S. 226
    , 235 (1985), "as
    sacred as the fee simple of the whites." Black's Law Dictionary
    describes "fee simple" as "the broadest property interest allowed
    - 37 -
    asserted that it "never intended to relinquish its ownership rights
    within the Penobscot River" and argued that Congress "inten[ded]
    that the Nation's reservation encompass ownership rights within
    and attending the Penobscot River."               It asked for a declaratory
    judgment that it has "exclusive authority to regulate hunting,
    trapping or other taking of wildlife within the waters of the Main
    Stem"   and    that   its    "law    enforcement       officers     have   exclusive
    authority to enforce the Nation's laws governing hunting, trapping
    or other taking of wildlife within the waters of the Main Stem."
    And   it   has   previously     sued    a   non-tribal     member     who    removed
    submerged logs from the River in tribal court for "trespass to
    tribal land" and "unlawful taking of tribal resources."                     Penobscot
    Nation v. Coffman, No. 7-31-03-CIV-04, slip op. at 4 (Penobscot
    Tribal Ct. Mar. 2, 2005).           The tribal court, invoking a version of
    the   treaty     argument,     held    that     the    River   is    part    of   the
    Reservation.     Id. at 3.     The tribal court then held that MIA "does
    not limit or define the tribal court's jurisdiction" and that the
    Supreme     Court     "has    recognized        that    tribal      courts    retain
    jurisdiction over [civil] disputes arising on a reservation."                     Id.
    at 2.      Because the Nation "retains aboriginal ownership of the
    by law." Black's Law Dictionary 760 (11th ed. 2019). In its brief
    to the original panel, the United States says that the Nation has
    an "ownership interest" in its Reservation and that "[i]t is
    unnecessary to determine whether the Nation's ownership interest
    in the land it has retained is best characterized as aboriginal
    title . . . ."

    Penobscot River, from bank to bank, limited only by the right of
    the public to use the river for navigation," the tribal court held
    that the Nation could successfully sue the non-tribal member and
    stated that "there is no right granted to an individual to conduct
    any . . . enterprise [other than the "limited public easement to
    pass    up   and   down   the   river   for   the   purpose   of   commercial
    transportation"] without tribal permission."             Id. at 3-4.      The
    stakes of reading the definition of Reservation to include the
    River are far greater than the dissent is willing to acknowledge.
    3. The Indian Canons of Construction Do Not Alter the
    Settlement   Acts'  Plain   Meaning  or   Override Clear
    Expressions of Tribal and Legislative Intent.
    The Nation and the United States next argue that three
    Indian canons apply to this case.         None of these canons alter the
    plain meaning of the Reservation's definition.20
    The first canon they cite says that "[s]tatutes are to
    be construed liberally in favor of the Indians, with ambiguous
    provisions interpreted to their benefit."           See County of Yakima v.
    Confederated Tribes & Bands of Yakima Indian Nation, 
    502 U.S. 251
    ,
    269 (1992) (quoting Montana v. Blackfeet Tribe, 
    471 U.S. 759
    , 766
    (1985) (alteration in original)).             This canon only applies to
    20 The State Defendants and State Intervenors argue that
    § 1725(h) and § 1735(b) of MICSA bar the application of any Indian
    canons of construction. Because we hold that the Indian canons

    Reservation in the Settlement Acts is not ambiguous.                           And even if
    the definition of Reservation were ambiguous and the canon applied,
    interpreting ambiguities to benefit the tribe does not mean that
    we must "disregard clear expressions of tribal and congressional

    circumstances'         and     'legislative           history,'          all      point[ed]

    an interpretation of the Reservation that excludes the Main Stem.

    treaties.     See Aroostook Band of Micmacs, 
    484 F.3d at 53
     (refusing

    involve any treaty").            They are statutes.         The treaty canon has no
    bearing on their interpretation.
    Finally,       they    cite     the    Indian     canon          saying     that
    Congress's intent to diminish a reservation must be clear.                                 See
    Parker, 
    136 S. Ct. at
    1078–79 ("'[O]nly Congress can divest a
    reservation of its land and diminish its boundaries,' and its
    intent to do so must be clear." (quoting Solem v. Bartlett,

    ,      345-46     (1941).         This   is    not       a    traditional
    diminishment case, as the United States admits in its brief to us,
    making the canon inapplicable.                     Regardless, the text of the
    Settlement Acts makes Congress's intent clear. "The most probative
    evidence      of    congressional         intent    [to    change      a   reservation's
    boundaries] is the statutory language used."                     Solem,

    .    The "unconditional commitment from Congress to compensate

    - 41 -
    insurmountable presumption that Congress meant for the tribe's
    reservation to be diminished."            
    Id. at 470-71
    ; see also McGirt,
    140 S. Ct. at        2468 ("When interpreting Congress's work in [a
    diminishment case], no less than any other, our charge is usually
    to ascertain and follow the original meaning of the law before
    us.").     As we have stated, the statutory language defining the
    Reservation makes it clear that Congress did not intend to include
    the River or submerged lands as part of the Reservation.                  Congress
    also agreed to put $13,500,000 into the Maine Indian Claims
    Settlement Fund and $26,800,000 into the Maine Indian Claims Land
    Acquisition   Fund    for     the   benefit    of    the   Nation.      
    25 U.S.C. § 1724
    (a), (c).      Congress intended these funds to compensate the
    Nation for giving up any claims to the land or natural resources
    not included in the Settlement Acts' definition of Reservation.
    See 
    Me. Rev. Stat. Ann. tit. 30, § 6203
    (12) (defining "Settlement
    Fund" as "the trust fund established for the . . . Penobscot Nation
    by   the   United    States    pursuant       to    congressional      legislation
    extinguishing aboriginal land claims in Maine").                   Indeed, MICSA
    forbids the Secretary of the Interior from using settlement fund
    money for the benefit of the Nation unless the Nation has "executed
    appropriate   documents       relinquishing        all   claims   to   the   extent
    provided by sections [of this Act approving prior transfer and
    discharging Maine from all obligations arising from any treaties
    or agreements with the Nation]."           
    25 U.S.C. § 1724
    (f).          Congress
    - 42 -
    intended the Settlement Acts to "provide the . . . Nation . . .
    with a fair and just settlement of their land claims,"                 
    id.
    § 1721(a)(7), and "clarify the status of other land and natural
    resources in the state of Maine,"           id. § 1721(b)(2), so any
    diminishment was intended.
    4. The Nation's Reading of Reservation Makes Other Parts of
    the Settlement Acts Incoherent and Inconsistent.
    Adopting   the   Nation   and   United   States'   reading   of
    "Penobscot Indian Reservation" would make other parts of the
    Settlement Acts incoherent and inconsistent.         See Robinson, 
    519 U.S. at 341
    .   One section of MIA dealing with regulatory takings
    of land within the Reservation says that "[f]or purposes of this
    section, land along and adjacent to the Penobscot River shall be
    deemed to be contiguous to the Penobscot Indian Reservation."          
    Me. Rev. Stat. Ann. tit. 30, § 6205
    (3)(A).        This statutory language
    makes it clear that, outside of § 6205(3)(A), land along and
    adjacent to the River is not contiguous to the Reservation.             If
    land along and adjacent to the River is not contiguous to the
    Reservation, then the Reservation cannot possibly include the
    River   itself.      To    interpret   it   otherwise    would   render
    § 6205(3)(A)'s language superfluous, something we must avoid.          See
    - 43 -
    City of Chicago, 141 S. Ct. at 91; Nielsen v. Preap, 
    139 S. Ct. 954
    , 969 (2019).
    Next, other provisions of the Settlement Acts explicitly
    address water, water rights, and submerged lands using different
    and    more        specific    language.         Reading      "Penobscot       Indian
    Reservation" to include these things when they are not mentioned
    anywhere      in    the   definition    would     make      the   Settlement    Acts
    inconsistent.        For example, the Settlement Acts define the phrase
    "land or other natural resources" -- not simply "land" -- to
    include "water and water rights."               
    25 U.S.C. § 1722
    (b); 
    Me. Rev. Stat. Ann. tit. 30, § 6203
    (3). Equating "land" with "land or other
    natural resources" in MICSA's definition of Reservation collapses
    this difference. See 
    25 U.S.C. § 1722
    (i) (defining the Reservation
    to include "lands," not "lands or other natural resources").
    Another section of the Settlement Acts, 
    Me. Rev. Stat. Ann. tit. 30, § 6207
    , shows that the drafters knew how to say "lands or
    waters" when that is what they intended.                 See 
    Me. Rev. Stat. Ann. tit. 30, § 6207
    (5)-(6)    (using   "lands      or    waters"    instead   of
    "lands").
    MIA also addresses the Nation's authority to regulate
    "any pond in which all the shoreline and all submerged lands are
    wholly    within      Indian     territory."     
    Id.
         § 6207(1)(B)    (emphasis
    added).       Penobscot Indian Territory is a defined term distinct
    from Penobscot Indian Reservation.              There is no reference in the
    - 44 -
    Settlement Acts to any submerged lands in the Reservation, and the
    use of "submerged lands" in § 6207(1)(B) is the only time the
    phrase    is    used.        Like   their    use    of    "land    or   other   natural
    resources" and "lands or waters" in other parts of MIA and MICSA,
    the drafters knew how to -- and did -- include more than land when
    they wanted to do so.               Cf. Caraco Pharm. Labs., Ltd. v. Novo
    Nordisk A/S, 
    566 U.S. 399
    , 416 (2012) ("[I]f we needed any proof
    that Congress knew how to say [a phrase] when it meant [that
    phrase], here we find it.").
    5. The Settlement Acts' Grant of Sustenance Fishing Rights to
    the Nation Does Not Alter § 6203(8)'s Plain Meaning.
    The    Nation    and    the   United       States   next    argue     that
    § 6207(4)'s          grant     of     sustenance      fishing       rights      to    the
    Passamaquoddy Tribe and the Nation "within the boundaries of their
    . . . Indian reservations" means that § 6203(8)'s definition of
    Reservation must include the River and its submerged lands.                          They
    say that interpreting § 6203(8) to exclude the River's waters and
    submerged      lands     is    inconsistent        with    §   6207(4)'s     grant    of
    sustenance fishing rights because the Nation can only exercise
    these rights in the River.21
    21   The Nation says that there are no waters on the surfaces
    of the islands to support fish. The State Defendants have admitted
    to this fact. MIA was amended in 1988 and 2009 to include lands
    other than the islands in the definition of "Penobscot Indian
    Reservation," but when the statute was originally passed in 1980,
    only the islands were included in that definition.
    - 45 -
    At this stage, our inquiry is focused on the meaning of
    Reservation      under      §   6203(8),     not   the   scope     of    the     Nation's
    sustenance fishing rights under § 6207(4).                       We consider whether
    the statutory scheme is coherent and consistent if Reservation is
    given its plain meaning and this meaning is applied consistently
    throughout the Settlement Acts, including to § 6207(4)'s grant of
    sustenance fishing rights.                See Barnhart, 
    534 U.S. at 450
    .               We
    hold that it is.          Whether the phrase "Indian reservations" used in
    § 6207(4)'s grant of sustenance fishing rights is itself ambiguous
    and susceptible to an interpretation that includes the Main Stem
    is an entirely separate issue that we address later.                             The fact
    that the Settlement Acts are coherent and consistent when "Indian
    reservations"        is    taken    to    incorporate      the    plain    meaning      of
    Penobscot Indian Reservation and exclude the Main Stem reinforces
    our conclusion that the plain meaning of "islands" controls.
    Section 6207(4) uses the phrase "Indian reservations" to
    refer     to   two   tribes'       reservations,     the    Passamaquoddy          Indian
    Reservation and the Penobscot Indian Reservation.                         Even if the
    Nation    cannot     exercise      its     sustenance    fishing        rights    on   its
    islands, there is nothing in the record to indicate that the
    sustenance fishing rights guaranteed to the Passamaquoddy Tribe by
    § 6207(4) is meaningless.22              The Nation and United States' argument
    22   The dissent argues that for the Passamaquoddy Tribe to
    have sustenance fishing rights, the definition "'Passamaquoddy
    - 46 -
    that § 6207(4) is incoherent as applied to the Nation alone ignores
    § 6207(4)'s broader application and context.     The section still
    has meaning as applied to the Passamaquoddy Tribe and is not, as
    the Nation and United States argue, rendered a nullity         when
    "islands" is given its plain meaning.
    The Nation, the United States, and the dissent read too
    much into the § 6207(4)'s grant of sustenance fishing rights.
    Section § 6203(8) gives a clear definition of "Penobscot Indian
    Reservation" that does not include the Main Stem.   The Settlement
    Acts' context and purpose confirm this reading, and they are fully
    coherent when the Reservation is given this meaning.   We have not,
    as the dissent argues, "set aside" § 6207(4) in determining what
    § 6203(8) means.   We have explicitly considered whether § 6207(4)
    makes sense when § 6203(8) is understood to exclude the Main Stem,
    and we conclude that it does.    See Ali v. Fed. Bureau of Prisons,
    Indian Reservation' means those lands as defined in [MIA]" in
    § 1722(f) of MICSA must mean that the Passamaquoddy Reservation
    includes lands and waters.    It says that this creates a "fatal
    flaw" in our argument that § 1722(i)'s similarly worded definition
    of Penobscot Indian Reservation means only lands. We see no flaw,
    as the language used to describe the parcels included in the
    Passamaquoddy Indian Reservation is very different from the
    language used in the definition of Penobscot Indian Reservation.
    For example, the inclusion of "Indian Township in Washington
    County" in the definition of Passamaquoddy Indian Reservation, 
    Me. Rev. Stat. Ann. tit. 30, § 6203
    (5), closely resembles the
    reservation of an "undivided tract of land described merely by
    exterior metes and bounds" that the Court has held includes "all
    of the land inside those boundaries including the river," Choctaw
    Nation, 
    397 U.S. at 628
    .
    - 47 -
    
    552 U.S. 214
    , 222 (2008) ("[O]ur construction . . . must, to the
    extent possible, ensure that the statutory scheme is coherent and
    consistent.").     The dissent insists that the "Penobscot Indian
    Reservation" defined in § 6203(8) must have a meaning consistent
    with the "Indian reservation[]" used in § 6207(4), but, as we have
    explained,   the    dissent's    interpretation   would   create   an
    inconsistency within § 6203(8) itself.    We cannot conclude, as the
    dissent would, that the Settlement Acts' drafters intended to
    override the text of § 6203(8) by implication when they used a
    different term in a different section of MIA that applies to more
    than one tribe.      We presume that the drafters did not "hide
    elephants in mouseholes."       Whitman v. Am. Trucking Ass'ns, 
    531 U.S. 457
    , 468 (2001).
    Despite our conclusion that § 6207(4) is still coherent
    when Reservation is given its plain meaning, we agree with the
    Nation and the United States that "Indian reservations" as used in
    § 6207(4) is itself ambiguous and that § 6207(4) grants the Nation
    sustenance fishing rights in the Main Stem.23     We do not, as the
    dissent says, hold that § 6207(4) must be read in this way.        And
    we do not agree that reading § 6207(4) this way means we must
    23   This is a separate issue from whether Maine has violated
    the Nation's rights under § 6207(4). As we explain later, we do
    not reach the Nation's sustenance fishing claim because the Nation
    lacks standing and the claim is not ripe.
    - 48 -
    deprive § 6203(8) of its plain meaning.                 The two provisions can
    and do coexist.
    Nothing     in   § 6207(4)'s        use   of   the    phrase    "Indian
    reservations" alters the plain meaning of § 6203(8).                     MIA itself
    tells us this.      Section 6203 says that the statute's definitions
    do not apply when "the context indicates otherwise."                       
    Me. Rev. Stat. Ann. tit. 30, § 6203
    .          The Supreme Court has also held that
    "context counts" and that "[t]here is . . . no 'effectively
    irrebuttable' presumption that the same defined term in different
    provisions of the same statute must 'be interpreted identically.'"
    Env't. Def. v. Duke Energy Corp., 
    549 U.S. 561
    , 575–76 (2007)
    (quoting United States v. Duke Energy Corp., 
    411 F.3d 539
    , 550
    (4th Cir. 2005)); see also Nw. Austin Mun. Util. Dist. No. One v.
    Holder,      
    557 U.S. 193
    ,        207     (2009)       ("[T]he      statutory
    definition . . . does not apply to every use of the term 'political
    subdivision' in the Act.").         The fact that § 6207(4) does not even
    use the defined term "Penobscot Indian Reservation" and nowhere
    indicates    that   "Indian    reservations"          incorporates      § 6203(8)'s
    definition     provides      even    more       evidence   that    the     Nation's
    sustenance    fishing      right    is    not    necessarily     limited     to   the
    Reservation.
    Section     6207(4)     has     meaning     and    that     meaning    is
    consistent with our holding as to § 6203(8).               Whether Congress was
    aware or not that there are no places to fish on the Reservation's
    - 49 -
    islands, § 6207(4) means that the Nation has the right to engage
    in sustenance fishing in the Main Stem.         That is a different right
    than the ownership rights the Nation is asserting under § 6203(8).
    Nothing in the legislative history indicates that the
    drafters of the Settlement Acts intended to restrict the Nation's
    existing right to fish in the Main Stem.24        To the contrary, their
    aim was to strengthen it.      The House and Senate Reports explain
    that Maine previously recognized the Nation's "right to control
    Indian subsistence hunting and fishing within their reservations"
    and that § 6207(4) ends "[t]he power of [Maine] to alter" these
    rights.25    See   Senate   Report   at   16;   House   Report   at   17-18.
    Legislative history from the passage of MIA also confirms that the
    drafters understood that the right to sustenance fish could be
    exercised in the Main Stem.    See Hearing on Legis. Doc. 2037 Before
    the Joint Select Comm. on Indian Land Claims, 109th Leg., 2d Reg.
    Sess. 55-56 (Me. 1980) (statement of Mr. Patterson that "the
    contemplation of this draft was to keep in place that same kind of
    right and provide that the Indians could continue to sustenance
    24   The record is clear that some members of the Nation have
    relied on sustenance fishing for generations before the Settlement
    Acts were passed.
    25   Before the Settlement Acts, Maine law said that the
    Commissioner of Inland Fisheries and Wildlife "shall issue
    a . . . fishing license to any [Penobscot] Indian." 1979 Me. Laws
    ch. 420 § 9(A). It also recognized the "right of Indians to take
    fish and wildlife for their own sustenance on their reservation
    lands." Id. § 9(B).
    - 50 -
    hunt and fish"); id. at 120 (raising concern that the sustenance
    fishing right would allow the Nation to cast a net "right across
    these rivers [including the Penobscot River] and completely wipe
    out . . . the spawning stock").
    Given this context, we conclude that the drafters did
    not intend for the phrase          "Indian reservations," as used in
    § 6207(4) and applied to the Nation, to have the same meaning as
    "Penobscot Indian Reservation."        Under this interpretation, the
    Settlement Acts give the Nation sustenance fishing rights in the
    Main Stem even though the River and its submerged lands are not
    part of the Reservation. There is no serious dispute about whether
    the Settlement Acts give the Nation sustenance fishing rights in
    the Main Stem.    They do.    The dispute here is over ownership of
    the River and its submerged lands, and we have explained why we
    have reached the interpretation we have.
    B. The Nation's Assertion that Maine Has Infringed Its Sustenance
    Fishing Rights Is Not Ripe and the Nation Lacks Standing to
    Pursue That Claim.
    We view differently the claim that Maine has infringed
    those fishing rights and that infringement justifies the issuance
    of   a   declaratory   judgment.      See   
    Me. Rev. Stat. Ann. tit. 30, § 6207
    (4).    The district court erred in issuing a declaratory
    judgment because the Nation lacks standing to pursue this claim
    and the claim is not ripe.         "The requirements for a justiciable
    case or controversy are no less strict in a declaratory judgment
    - 51 -
    proceeding than in any other type of suit."                 Ala. State Fed'n of
    Labor v. McAdory, 
    325 U.S. 450
    , 461 (1945).            We vacate the district
    court's ruling on this issue and order dismissal of the claim
    without prejudice.
    Article III of the Constitution limits federal courts'
    jurisdiction to cases or controversies.               See, e.g., Students for
    Fair Admissions, Inc. v. President & Fellows of Harvard Coll., 
    980 F.3d 157
    , 182–83 (1st Cir. 2020) (citing Warth v. Seldin, 
    422 U.S. 490
    ,    498   (1975)).    "The     doctrines    of    standing      and   ripeness
    'originate' from the same Article III limitation."                        Susan B.
    Anthony List v. Driehaus, 
    573 U.S. 149
    , 157 n.5 (2014).
    1. The Nation Does Not Have Standing to Pursue Its Claim That
    Maine Has Violated the Sustenance Fishing Rights Guaranteed
    to it Under MIA.
    To have standing, a plaintiff must "have (1) suffered an
    injury in fact, (2) that is fairly traceable to the challenged
    conduct of the defendant, and (3) that is likely to be redressed
    by a favorable judicial decision."          Spokeo, Inc. v. Robins, 
    136 S. Ct. 1540
    , 1547 (2016).         The Nation has suffered no injury in fact.
    An injury in fact is "'an invasion of a legally protected
    interest' that is 'concrete and particularized' and 'actual or
    imminent, not conjectural or hypothetical.'"                
    Id. at 1548
     (quoting
    Lujan    v.   Defenders   of    Wildlife,     
    504 U.S. 555
    ,   560   (1992)).
    Sometimes, the threat of enforcement alone "may suffice as an
    'imminent' Article III injury in fact."             Reddy v. Foster, 845 F.3d
    - 52 -
    493, 500 (1st Cir. 2017) (quoting Susan B. Anthony List, 573 U.S.
    at 158).    The Nation argues that it has suffered an injury in fact
    because the Schneider Opinion is a concrete and particularized
    imminent threat to its sustenance fishing rights.
    We see no imminent threat.           The Schneider Opinion does
    not even mention the Nation's sustenance fishing rights.                   It does
    not prevent any tribal member from engaging in sustenance fishing.
    Maine   has    not   prevented    any     Nation   member       from   engaging   in
    sustenance fishing.         Indeed, Maine has a "long-standing policy of
    not interfering with tribal members' sustenance fishing in the
    Main Stem" and has represented to us that it has "no intention of
    changing that policy."         Under circumstances like these, when "a
    future injury is 'too speculative for Article III purposes' and no
    prosecution     is   even    close   to    impending,"      a    plaintiff   lacks
    standing.     See Reddy, 845 F.3d at 500 (quoting Blum v. Holder, 
    744 F.3d 790
    , 799 (1st Cir. 2014)).
    There is no support in the record for the Nation's claims
    that the Schneider Opinion threatens its sovereignty or regulatory
    authority.     The cases cited by the Nation for the proposition that
    tribes are granted special solicitude as sovereigns in the standing
    analysis are also inapposite.             In those cases, there was actual
    harm to tribal members or people operating in tribal territory
    that threatened the tribes' sovereignty.              See Moe v. Confederated
    Salish & Kootenai Tribes of Flathead Rsrv., 
    425 U.S. 463
    , 468-69,
    - 53 -
    469 n.7 (1976) (tribe had standing to challenge Montana's statutory
    scheme for assessment and collection of personal property taxes
    from tribe's members); White Mountain Apache Tribe v. Bracker, 
    448 U.S. 136
    , 139-40 (1980) (tribe had standing to challenge Arizona's
    taxes   on   a   logging   company   operating   solely    on    an   Indian
    reservation when the tribe agreed to reimburse the company for
    taxes it paid for its on-reservation activity).           The Nation has
    not shown that it faces an actual or imminent harm in this case.
    2. The Nation's Claim That Maine Has Violated the Sustenance
    Fishing Rights Guaranteed to it Under MIA Is Not Ripe.
    The Nation's claim is also not ripe.         Our "[r]ipeness
    analysis has two prongs: 'fitness' and 'hardship.'"              See Reddy,
    845 F.3d at 501 (citing Texas v. United States, 
    523 U.S. 296
    , 300-
    01 (1998)).      The fitness prong asks "whether the claim involves
    uncertain and contingent events that may not occur as anticipated
    or may not occur at all."       Town of Barnstable v. O'Connor, 
    786 F.3d 130
    , 143 (1st Cir. 2015) (quoting Ernst & Young v. Depositors
    Econ. Prot. Corp., 
    45 F.3d 530
    , 536 (1st Cir. 1995)).           The hardship
    prong is prudential and asks what harm would come to those seeking
    relief if we withheld a decision.       Reddy, 845 F.3d at 501 (citing
    Labor Relations Div. of Constr. Indus. of Mass., Inc. v. Healey,
    
    844 F.3d 318
    , 326 (1st Cir. 2016)).
    Neither prong is met here.     On the fitness prong, the
    Nation's claim depends on uncertain or contingent events.             There
    - 54 -
    is   no   evidence   that   Maine   has       interfered   with   the   Nation's
    sustenance fishing rights or that it may do so in the future.                Cf.
    McInnis-Misenor v. Me. Med. Ctr., 
    319 F.3d 63
    , 72 (1st Cir. 2003)
    ("[T]hat the future event may never come to pass augurs against a
    finding of fitness.").      There is no concrete dispute before us.
    The hardship prong is also not met.                  Our analysis
    "focuses on 'direct and immediate' harm."            
    Id. at 73
    .    "[T]here is
    no apparent prejudice to the plaintiffs if they must wait until
    their claims ripen to sue" here because "[t]hey are not 'required
    to engage in, or to refrain from, any conduct, unless and until'"
    Maine     either   interferes   with    the    Nation's    sustenance    fishing
    rights or demonstrates an intent to do so.            Reddy, 845 F.3d at 505
    (quoting Texas, 
    523 U.S. at 301
    ).
    III.
    The judgment of the district court is affirmed as to the
    definition of "Penobscot Indian Reservation" under 
    Me. Rev. Stat. Ann. tit. 30, § 6203
    (8) and 
    25 U.S.C. § 1722
    (i) and vacated with
    instructions to dismiss without prejudice for want of jurisdiction
    as to the declaratory judgment regarding the sustenance fishing
    rights under 
    Me. Rev. Stat. Ann. tit. 30, § 6207
    (4).              No costs are
    awarded.
    - Concurring and Dissenting Opinion Follows -
    - 55 -
    BARRON,   Circuit    Judge,    with   whom   THOMPSON,    Circuit
    Judge, joins, concurring in part and dissenting in part. The State
    of Maine enacted the Maine Implementing Act ("MIA") in 1980 in
    tandem with Congress's passage that same year of the Maine Indian
    Claims Settlement Act ("MICSA").      Together, the measures sought to
    settle then-pending litigation that had called into question,
    among other things, the legal status of cessions of land "on both
    sides of the Penobscot [R]iver" that the Penobscot Nation had made
    first to Massachusetts, and then to Maine, in treaties around the
    turn of the nineteenth century. The questions that we must resolve
    in this appeal concern one aspect of the settlement that these
    Acts brought about -- the nature of the rights in certain waters
    of the Penobscot River that the Nation would continue to enjoy.
    I agree with the majority that the Settlement Acts, in
    effectively blessing the Penobscot Nation's long-ago transfers of
    land beyond the banks of the river, did not leave the Nation with
    nothing in return as to the waters in between.          In particular, I
    agree with the majority that those Acts secure to the Nation a
    limited right that entitles its members to fish in those waters
    for their own sustenance.     But, I cannot agree with the majority's
    further and more consequential conclusion that the Acts give the
    Nation no further rights in those waters.
    The   majority    arrives     at   this   result   by    narrowly
    construing the provision in the Acts that purports to define the
    - 56 -
    "Penobscot Indian Reservation" so that it excludes altogether the
    waters of the Penobscot River.               The consequence is that the
    sovereign rights to regulate the taking of wildlife that the
    Settlement Acts expressly entitle this riverine Nation to exercise
    throughout its "Reservation" extend to no portion of the Penobscot
    River itself.
    Yet, as I will explain, the statutory text does not
    compel such a landlocked construction of the "Penobscot Indian
    Reservation."         In fact, a different provision of the same statute
    that        defines    the   "Reservation"     expressly     describes    the
    "boundaries" of the "Penobscot Nation . . . Indian reservation[]"
    in terms that even the majority agrees include the portions of the
    Penobscot River that are in dispute.          See 
    Me. Rev. Stat. Ann. tit. 30, § 6207
    (4).
    The problem with the majority's narrow construction,
    however, runs deeper still.        The Settlement Acts were intended in
    significant part to make up for the fact that the Nation had
    entered into the treaties at the heart of the underlying disputes
    over    land     transfers   without   the    federal    authorization   that
    Congress had early on required in the Trade and Intercourse Act of
    1790 ("the Nonintercourse Act"), see 
    25 U.S.C. § 1721
    (a)(1), to
    protect tribes from states swindling them.26            After all, it was the
    26 In Joint Tribal Council of the Passamaquoddy Tribe v.
    Morton, 
    528 F.2d 370
     (1st Cir. 1975), this Court confirmed that
    - 57 -
    lack of any such congressional authorization for those treaties
    that led the Nation to assert that the land transfers that it had
    made in them were without legal effect, thereby precipitating the
    title disputes that the Settlement Acts aimed to resolve.               It is
    thus tragically ironic, in my view, that the majority now construes
    the Acts to leave the Nation with even fewer sovereign rights in
    the river that has been its lifeblood than it had reserved for
    itself in its own unprotected dealings with those two states so
    early on in our history.
    Moreover, precisely because text, history, and purpose
    undermine    the   notion   that   the      definition   of   the     Nation's
    "Reservation" in the Settlement Acts clearly excludes the waters
    at issue, longstanding principles of interpretation require that
    we construe that definition to include those waters.                For, those
    principles require that we resolve an ambiguity on that score in
    the Nation's favor, see County of Yakima v. Confederated Tribes &
    Bands of the Yakima Indian Nation, 
    502 U.S. 251
    , 269 (1992), and,
    at the very least, we confront such an ambiguity here.
    the Nonintercourse Act applied to the Passamaquoddy Tribe and
    created a trust relationship between the United States and that
    tribe.   See 
    id. at 373
    .     The Penobscot Nation's land claims
    preceding the MICSA were premised on the theory -- which is not
    challenged here -- that the same would be true of the Penobscot
    Nation. See Joint Tribal Council of the Passamaquoddy Tribe v.
    Morton, 
    388 F. Supp. 649
    , 654 n.6 (D. Me. 1975).
    - 58 -
    I.
    The     MICSA     provides    that    the    "'Penobscot    Indian
    Reservation' means those lands as defined in the [MIA]." 
    25 U.S.C. § 1722
    (i).   The MIA in turn provides that the
    "Penobscot Indian Reservation" means the
    islands in the Penobscot River reserved to the
    Penobscot Nation by agreement with the States
    of Massachusetts and Maine consisting solely
    of Indian Island, also known as Old Town
    Island, and all islands in that river
    northward thereof that existed on June 29,
    1818, excepting any island transferred to a
    person or entity other than a member of the
    Penobscot Nation subsequent to June 29, 1818,
    and prior to the effective date of this Act.
    
    Me. Rev. Stat. Ann. tit. 30, § 6203
    (8).
    The ultimate question that we must decide on appeal, in
    light of these two provisions, is a relatively discrete one of
    statutory interpretation.        It concerns whether the definition of
    the   "Penobscot    Indian    Reservation"      in   § 6203(8)   of   the   MIA
    encompasses only the uplands of the individual islands to which it
    refers -- which is all the majority concludes that it includes --
    or also the whole of the area comprising the uplands of those
    islands, waters included -- which is what the Penobscot Nation
    contends that it does.27
    27  In construing the Settlement Acts, we have held that
    because the MICSA adopted the MIA, interpretative questions about
    provisions of the MIA are federal questions. See Penobscot Nation
    v. Fellencer, 
    164 F.3d 706
    , 708 (1st Cir. 1999) (explaining that
    "[b]ecause the phrase 'internal tribal matters' was adopted by the
    federal Settlement Act, the meaning of that phrase [which does not
    - 59 -
    Before answering that question, however, it helps to
    clarify more precisely what is at stake in this interpretive
    dispute, as there appears to be some confusion on that point.
    Critical to sorting out that confusion is a recognition that
    § 6203(8) of the MIA, by its own terms, is definitional rather
    than substantive.   It only purports to define, in other words,
    what the term "Penobscot Indian Reservation" in the Settlement
    Acts themselves -- when used elsewhere in them -- means.   It does
    not itself purport to establish a reservation in the typical sense.
    This fact is significant.     In consequence of it, the
    meaning assigned to "Penobscot Indian Reservation" in § 6203(8) of
    the MIA must be understood in connection with the concrete rights
    and authorities that the Settlement Acts themselves provide that
    the Penobscot Nation enjoys within what those same Acts call the
    Nation's "Reservation."   As a result, the lengthy arguments of the
    State of Maine and the Intervenors that "ownership" of the relevant
    stretch of the river, including its submerged lands, is at issue
    in this appeal are, in the end, a distraction.     Whatever claims
    the Penobscot Nation might have in that regard, the Nation seeks
    here to prove with respect to the definition of the "Penobscot
    appear in the MICSA itself] raises a question of federal law").
    Accordingly, although § 6203(8) of the MIA is itself a provision
    of state law, the parties do not dispute that its meaning is a
    question of federal law such that we have jurisdiction under 
    28 U.S.C. § 1331
    .
    - 60 -
    Indian    Reservation"   in   § 6203(8)   of   the   MIA   only   that   the
    definition is broad enough to ensure that, when it is plugged into
    the substantive provisions of the MIA that are keyed to it, the
    Nation will have the same right to regulate hunting and trapping
    in the waters in that stretch of the river that the Nation
    generally has under those same substantive provisions within the
    boundaries of the "Penobscot Indian Reservation."28
    Having clarified that much up front, though, there is
    still one further threshold point to address.              It concerns the
    interpretive resources that we may draw upon to decide how best to
    determine whether the definition of the term "Penobscot Indian
    Reservation" in § 6203(8) of the MIA refers to the relevant waters
    or only to the uplands located in them.        I thus begin my analysis
    there, as a consideration of this question of interpretive method
    demonstrates, in my view, the errors in the majority's rationale
    for its lead holding, in which the majority gives this definition
    in § 6203(8) of the MIA a narrow, uplands-only construction.
    A.
    The majority explains that in construing the definition
    of the "Penobscot Indian Reservation" in § 6203(8) of the MIA we
    may not draw upon what history shows about the Penobscot Nation's
    28   For that reason, I do not consider the argument that
    adjudication of the ownership of the river would require joinder
    of riverfront landowners or that fee simple title in the river is
    owned in trust by the State.
    - 61 -
    past understandings regarding its rights in the waters at issue.
    The majority further explains that in construing that definitional
    provision we may not rely on any of the canons of construction
    relating to Indian tribes.
    In    the   majority's   view,    we   must   labor     under   these
    interpretive constraints because this statutory provision's text
    -- given the ordinary meaning of the words in it -- in and of
    itself compels an uplands-only reading.            The majority emphasizes
    that a statute's words should be given their ordinary meaning if
    the legislature does not define them.          See Maj. Op. 11-12, 11 n.5.
    It then asserts that the ordinary meaning of the word "islands" in
    § 6203(8) of the MIA -- and "lands" in the provision of the MICSA
    that cross-references that provision of the MIA -- conveys an
    uplands-only, not a waters-inclusive, understanding.                Maj. Op. 12-
    13.   Thus, the majority concludes, because neither the word
    "islands" nor the word "lands" is defined in either the MIA or the
    MICSA, the ordinary, water-less meaning of "islands" and "lands"
    controls.
    The    majority    finds    additional        support     for    this
    dictionary-based reading of the relevant statutory text in the
    fact that the Settlement Acts do not use a single geographic name
    for the islands referred to in § 6203(8). Nor, the majority points
    out, do those Acts describe the islands at any point with reference
    to any words that require the islands to be treated as a collective
    - 62 -
    -- and thus as an area including the surrounding waters -- rather
    than as individual land masses.             See Maj. Op. 17.
    The   majority   does    address    the   contention    that   the
    qualifier "reserved to the Penobscot Nation by agreement" in
    § 6203(8) of the MIA suggests that we should set the dictionary
    aside    and    consult   history      to   discern   whether   what   had    been
    "reserved . . . by agreement" encompasses any of the waters that
    surround the islands' uplands.               Maj. Op. 21-22.      The majority
    concludes, however, that the text of § 6203(8) makes perfectly
    clear that the "islands" to which that definitional provision is
    referring are only those that the "consisting" phrase within that
    same provision describes them to be.              See Maj. Op. 22-23.
    The majority explains in this regard that the word
    "islands" is used in that phrase in conjunction with the words
    "solely" and "in the Penobscot River," and it concludes that those
    two modifiers themselves support a dictionary-based (and thus, in
    the majority's view, uplands-only) understanding of "islands."
    See Maj. Op. 13-14, 17.         In fact, the majority asserts, the word
    "islands" in § 6203(8) of the MIA would have to bear two distinct
    meanings in the same provision -- one including waters and one not
    -- for the area-based construction of § 6203(8) of that statute
    for which the Nation advocates to be a viable one.                See Maj. Op.
    25-26.
    - 63 -
    B.
    The majority is right that we have no warrant to rely on
    extra-textual interpretive aids to construe the definition in
    § 6203(8) of the MIA if that text is as clear as the majority
    concludes that it is.    But, even when a statute uses words that on
    their own bear an ordinary meaning that is plain, there may still
    be ambiguity as to whether it is plain that those words should be
    given that ordinary meaning.      See Yates v. United States, 
    574 U.S. 528
    , 537 (2015) ("Whether a statutory term is unambiguous . . .
    does not turn solely on dictionary definitions of its component
    words. Rather, '[t]he plainness or ambiguity of statutory language
    is determined [not only] by reference to the language itself, [but
    as well by] the specific context in which that language is used,
    and the broader context of the statute as a whole.'" (alterations
    in original) (quoting Robinson v. Shell Oil Co., 
    519 U.S. 337
    , 341
    (1997))); see also Antonin Scalia & Bryan A. Garner, Reading Law:
    The Interpretation of Legal Texts 70 (2012) ("One should assume
    the contextually appropriate ordinary meaning unless there is
    reason to think otherwise . . . . which ordinarily comes from
    context.");   id.   at   73   ("Sometimes   context   indicates   that   a
    technical meaning applies.").
    Thus, even if the majority is right that the words
    "lands" and "islands" in isolation bear an ordinary meaning that
    plainly excludes waters offshore, we still must assess whether
    - 64 -
    those words carry their ordinary meanings here, given the specific
    way in which those words are used in the statutory provisions at
    hand.       In my view, there is good reason to conclude from the text
    of § 6203(8) of the MIA alone that those words do not.
    1.
    For starters, the word "islands" appears in § 6203(8) of
    the MIA only as a constituent part of a larger phrase.                   See Bostock
    v. Clayton County, 
    140 S. Ct. 1731
    , 1750 (2020).                         That larger
    phrase, moreover, refers to a specific group of islands both for
    the purpose of defining where as part of a settlement of rights to
    land    and     natural      resources     the   Nation    may    exercise    certain
    sovereign rights and in terms of what had been "reserved to the
    Penobscot Nation by agreement," 
    Me. Rev. Stat. Ann. tit. 30, § 6203
    (8).
    The plain text of § 6203(8) of the MIA in these ways
    supplies a reason why the word "islands" as it appears in this
    context       might    not   mean   what    it   ordinarily      would   if   it   were
    considered on its own.              That being so, the same is necessarily
    also true of the word "lands."               That word, after all, appears in
    the provision of the MICSA that directs the reader to § 6203(8) of
    the     MIA    to     find   the    definition     of     the    "Penobscot    Indian
    Reservation."29
    29 No party has argued on appeal that we should understand
    the fact that this provision of the MICSA refers to "those lands
    - 65 -
    Precedent from the Supreme Court of the United States
    supports the conclusion that the features of the text of § 6203(8)
    of the MIA that I have just described render that provision more
    ambiguous in the relevant respect than the majority allows.              On
    more than one occasion, the Court has held that reservation-
    defining statutes refer to waters despite their failure to make
    any express reference to those waters and despite their use of
    geographic terms that, in and of themselves, ordinarily might be
    understood to refer to dry land only.
    For   example,    in   Alaska    Pacific   Fisheries   v.   United
    States, 
    248 U.S. 78
     (1918), the Court considered a statute that
    defined a reservation as consisting of "the body of lands known as
    Annette Islands" and held that, textually speaking, that larger
    phrase arguably could refer to "the area comprising the islands"
    -- and thus an area inclusive of waters -- rather than only to the
    uplands in that area.      
    Id. at 86-89
    .     For that reason, the Court
    determined, only an inquiry into sources beyond those that would
    merely disclose the ordinary meaning of the words "lands" or
    "islands" could reveal the intended meaning of the larger phrase
    in which those words were embedded.         See 
    id. at 87
    .30
    as defined in the [MIA]," 
    25 U.S.C. § 1722
    (i) (emphasis added), to
    limit the definition in § 6203(8) of the MIA.
    30   The majority notes, Maj. Op. 16, that Alaska Pacific
    Fisheries concerns Alaska and that, as the Supreme Court just
    observed, "[t]he 'simple truth' . . . is that 'Alaska is often the
    exception, not the rule.'" Yellen v. Confederated Tribes of the
    - 66 -
    Similarly, in Hynes v. Grimes Packing Co., 
    337 U.S. 86
    (1949), the Court held that the statutory phrase "any other public
    lands which are actually occupied by Indians or Eskimos within
    said Territory" did not, in consequence of the ordinary meaning of
    the word "lands" alone, resolve whether the reservation that it
    purported to define included coastal waters.     See 
    id. at 91-92, 110-11
    .   Thus, the Court there, too, concluded that only a broader
    consideration of legislative purpose, as informed by the history
    of how the native peoples interacted with those waters, could
    resolve whether the phrase invoking the word "lands" did or did
    not include those waters.   
    Id. at 115-16
    .31
    The Court later explained in Amoco Production Co. v.
    Village of Gambell, 
    480 U.S. 531
     (1987), that an extra-textual,
    historically informed inquiry was proper in each of those earlier
    cases precisely because the reservation-defining statute had in
    Chehalis Rsrv., ___ S. Ct. ___, 
    2021 WL 2599432
    , at *3 (2021) [No.
    20-543] (quoting Sturgeon v. Frost, 
    577 U.S. 424
    , 440 (2016)).
    But, there is no suggestion in Alaska Pacific Fisheries,
    Confederated Tribes of the Chehalis Reservation (which does not
    reference Alaska Pacific Fisheries), or any case in between that
    would provide a basis for concluding that the Court would find the
    relevant text in the statute set forth in Alaska Pacific Fisheries
    to exclude the waters surrounding the Annette Islands if that
    collection of islands happened to have been located somewhere other
    than Alaska.
    31   True, Hynes is also a case from Alaska, but not even the
    majority suggests that its state of origin was what made the
    relevant phrase there not susceptible of being construed with only
    a dictionary as an aid.
    - 67 -
    each instance used a phrase that, despite the common geographic
    terms   embedded      therein,       had    no    "precise     geographic/political
    meaning[]     which    would    have       been     commonly   understood,        without
    further     inquiry,    to    exclude       the   waters."          
    Id.
        at   547   n.14.
    Accordingly, the Court determined that, given the larger phrase
    used, fidelity to text had required in each case the conclusion
    that "[t]he meaning of the phrase[] had to be derived from [its]
    context in the statute[]."            
    Id.
    Against that precedential backdrop, the fact that we
    confront here not just the word "islands" -- or "lands" -- but a
    larger phrase referring to a specific set of "islands" should give
    us   some   reason     to    pause   before       we   turn    to    the    dictionary's
    definition of those discrete words to discern the meaning of that
    larger phrase.         As in Alaska Pacific Fisheries and Hynes, the
    phrase that matters here is configured in a way that at least
    raises the question whether it refers to an area inclusive of
    waters, despite the fact that the only geographic terms used in
    connection with that phrase are "islands" and "lands."                            That is
    not because we have no choice but to conclude that the word
    "islands" is itself being used -- unusually -- as a "term of art."
    See Maj. Op. 21-22.            It is because we are construing a larger
    phrase, of which "islands" is just a key part, and not that word
    on its own.
    - 68 -
    Consider that, like the reference to "Annette Islands"
    in Alaska Pacific Fisheries, the reference to "islands" in the
    relevant phrase here concerns a discrete and definable grouping,
    rather than a disparate assortment, of land masses that is located
    in one continuous and discernable stretch of waters.     For this
    reason, geographic reality no more rules out an area-based reading
    of the relevant phrase than it did in Alaska Pacific Fisheries.
    Consider also that, like the statute in Alaska Pacific
    Fisheries, this one refers to the "islands" as an undifferentiated
    group -- "all islands" -- without purporting to distinguish which
    among them are "the site of [the tribe's] village[s], or the
    island[s] on which they were dwelling," Alaska Pac. Fisheries, 
    248 U.S. at 89
    .    For this reason as well, the text is arguably
    suggestive of an area comprising the islands, waters included.32
    There is, however, yet one more reason to be wary of
    reaching too quickly for the dictionary -- and thus looking at no
    32   The United States argues that "islands" could be broader
    than the discrete uplands because, under Massachusetts and Maine
    common law, island estates ordinarily included submerged lands and
    associated rights to riverine resources -- thus, with respect to
    any individual island, there may be an ambiguity at least as to
    whether it would include submerged lands to the thread of the
    river. The State challenges this understanding of the relevant
    common law.   In light of Alaska Pacific Fisheries, and for the
    reasons set forth below, I find that "islands in the Penobscot
    River reserved to the Penobscot Nation by agreement" is
    sufficiently susceptible of an area-based understanding that it is
    not necessary to reach this dispute about what each individual
    island may include in terms of attendant waters under state common
    law.
    - 69 -
    other extra-textual source -- to determine the meaning of § 6203(8)
    of the MIA with respect to the uplands/waters issue.     As I have
    mentioned, the larger phrase that we are concerned with in that
    provision specifies that it is referring to what was "reserved to
    the Penobscot Nation by agreement with the States of Massachusetts
    and Maine."   That same phrase then goes on to reference a specific
    date in 1818 in defining what was "reserved," and that date, of
    course, is the one on which the Penobscot Nation signed the
    "treaty" with Massachusetts in which the Nation purported to cede
    the lands "on both sides of the . . . river" while keeping "all
    the islands" in the relevant stretch of the river.   Treaty Made by
    the Commonwealth of Massachusetts with the Penobscot Tribe of
    Indians, June 29, 1818, in Acts and Resolves Passed by the Twenty-
    Third Legislature of the State of Maine, A.D., 1843, at 253, 253-
    54 (Augusta, Wm. R. Smith & Co. 1843) [hereinafter 1818 Treaty].
    Quite obviously, no dictionary can reveal the nature of
    an earlier agreed-to reservation between specific historically
    rooted sovereign actors, see Amoco Prod. Co., 
    480 U.S. at
    547 n.14,
    just as no dictionary could have given content to the use-based
    qualifier that the relevant statute in Hynes included.   Given that
    the "Reservation" here concerns a group of islands in a stretch of
    water that marks out a cohesive area in its own right, there is no
    reason rooted in fidelity to text that would require us to construe
    the phrase as if the terms of, and understandings about, that prior
    - 70 -
    agreement are wholly beside the point insofar as those terms and
    understandings would support an area-based rather than uplands-
    only construction.      Rather, the text would seem rather strongly to
    suggest that the drafters intended to give effect to these very
    understandings in § 6203(8) even if they would support such an
    area-based construction.         Indeed, even Maine adamantly took the
    position in earlier litigation that a proper determination of the
    "Reservation"     necessarily     "involves      analysis    of    the   relevant
    treaties referenced in the Reservation definitions in the [MIA]
    including   the    historical     transfers      of    Reservation    lands    and
    natural resources."       Brief of Petitioner State of Maine at 58,
    Maine v. Johnson, 
    498 F.3d 37
     (1st Cir. 2007) (Nos. 04-1363, 04-
    1375) (emphases added).
    2.
    For   all   these    reasons,    the      majority's    uplands-only
    construction of § 6203(8) -- rooted as it is in a claim about the
    limited, dictionary-based interpretive method that we must use --
    is less clearly one that the text in and of itself compels than
    the majority contends.         That is especially so when one recognizes
    that the majority's construction is hard to square with standard
    interpretive      practices,    because     it   appears    to     attribute   no
    independent meaning to the phrase "reserved . . . by agreement."
    As we have seen, the majority appears to treat the
    "reserved . . . by agreement" qualifier as if it were superfluous.
    - 71 -
    In fact, because that qualifier precedes the "consisting" phrase,
    § 6203(8) changes not a bit in the majority's view if the qualifier
    is omitted.33
    We are generally loath, however, to treat statutory
    words as wasted.      Nor would there appear to be any special reason
    to conclude that the words to which the majority assigns no import
    here are ones that need not have been included at all.
    Those words appear alongside the provision's express
    reference to the 1818 date.          That is the date of an agreement
    excluding "all islands" in the river from the cessions of lands
    "on both sides of" it that the Nation had purported to make.              The
    joint     inclusion   of   the   reference   to   islands   that   had   been
    "reserved . . . by agreement" and the date of a past agreement
    33   The majority asserts that the qualifier is necessary to
    clarify that islands transferred by the Nation prior to 1818 are
    not part of the Penobscot Indian Reservation. Maj. Op. 23-24, 23
    n.11. The majority does not assert, however, that any island was
    transferred by the Nation before 1818, and the 1818 treaty's
    "covenant . . . that [the Nation] shall have, enjoy and
    improve . . . all the islands in the Penobscot river above Oldtown
    and including said Oldtown island," 1818 Treaty, supra, at 254,
    suggests that there had been no such transfer, at least in the
    relevant stretch of the river. If any island not in that stretch
    of the river had been transferred before that date, § 6203(8) would
    already exclude that island by virtue of the "consisting solely"
    phrase. The "reserved . . . by agreement" language thus would not
    in that event be necessary to make that exclusion clear. Aside
    from the counterfactual nature of the majority's explanation of
    the function of "reserved . . . by agreement," it would be strange
    in light of the drafters' explicit exclusion of post-1818 transfers
    to conclude that the drafters effected the exclusion of pre-1818
    transfers in such an oblique way.
    - 72 -
    making a reservation involving those very islands surely provides
    some reason to think that the ordinary meaning of "islands" might
    not be an entirely reliable guide to § 6203(8)'s meaning insofar
    as the agreement that had been struck by the Nation on that date
    reflected a different understanding of what the Nation had reserved
    than the dictionary definition of "island" would supply.             And, as
    I have noted, Maine itself once read the text in just this
    historically    informed    manner,     taking   the   position    that    the
    definition of the "Penobscot Indian Reservation" in § 6203(8) of
    the MIA had to be construed in light of the understandings of the
    parties to the 1818 treaty and not without considering them at
    all.
    Perhaps, then, the initial phrase in § 6203(8) of the
    MIA, which contains this backward-looking qualifier about what had
    been agreed to in the past, is best construed to have been intended
    to give effect to the outcome of an agreement as the parties to it
    understood it when it was struck centuries before.                 True, the
    definition does not just end with the reference to what had been
    "reserved . . . by agreement."         It goes on to include the trailing
    "consisting" and "excepting" phrases.         But, the inclusion of those
    phrases hardly compels a reading that would make the reference to
    the prior agreement of no import.             Instead, those phrases may
    comfortably    be   read   to   be    usefully   clarifying   --    just    as
    settlements of disputes over the meaning of old agreements often
    - 73 -
    do   --    critical   details       concerning   what    the      parties    to   the
    settlement that the Settlement Acts effected understood to have
    been reserved in the earlier treaty.
    Indeed, a comparison of the 1818 treaty and § 6203(8) of
    the MIA reveals that the drafters of the MIA merely revised the
    more      encompassing      "including"     phrase      of     that    treaty      by
    substituting for it the more limiting "consisting solely" and
    "excepting" phrases.         By doing so, they accounted for post-treaty
    developments      (whether    man-made      or   naturally        occurring)      that
    obviously could not have been known in 1818.                   They thus ensured
    through that revision of the treaty's language that § 6203(8) of
    the MIA would account for matters that -- given their late-breaking
    nature -- cannot have been understood to have been carefully
    considered by the treaty parties at that earlier time.
    Of   course,    even    on   this   reading     of    § 6203(8),      the
    question would remain as to whether the larger phrase containing
    "the islands" in § 6203(8) of the MIA is referring to merely the
    uplands in the area demarcated by those "islands" or to the area
    comprising them and thus the waters in that area, too.                      The text
    of this provision -- at least in and of itself -- cannot be said
    to resolve that question conclusively in the Nation's favor, even
    if it might be so read.             It all would depend, even on such a
    historically informed reading, on what the parties to the 1818
    - 74 -
    treaty understood to have been "reserved . . . by agreement" way
    back when.
    But, I do note that an area-based reading does give a
    meaningful role to the "reserved . . . by agreement" language that
    the majority's uplands-only reading does not.                     It reads that
    language to have been included because the drafters were intent on
    capturing past understandings arising from past dealings.                        For
    this    reason,      too,   the    "reserved . . .      by   agreement"    language
    should warn the reader away from an ahistorical, dictionary-based
    understanding of what is meant by "islands."
    I    recognize     that    the     majority   contends     that   the
    "consisting" phrase's own text in and of itself rules out an area-
    based reading, no matter what the history of past dealings might
    show.     The majority explains that this is so in part because the
    word "solely" in that phrase compels the conclusion that the
    drafters of § 6203(8) of the MIA intended to debar the islands'
    surrounding waters from being within the "Reservation."                    See Maj.
    Op. 14.
    But, I cannot agree with that analysis.                    The word
    "solely," given its placement, is, as a matter of grammar, merely
    narrowing the general set of "islands" that precedes it to a
    smaller set of "islands" that are thereafter described.                     It thus
    cannot    be       specifying     an   uplands-only    rather   than    area-based
    understanding of "islands" any more than the use of the word
    - 75 -
    "solely" in the phrase "ship the bikes that had been ordered,
    consisting solely of the bikes in storage" could be read to be
    sorting between bikes that have baskets and those that do not.
    And that is especially so because the group of islands described
    after "solely," like the group of islands described before that
    term, is a group that, by virtue of how the islands are situated
    relative to one another, may easily be understood to demarcate an
    area comprising the islands.
    Nor can I agree with the majority's related contention
    that the phrase "in the Penobscot River" requires an uplands-only
    reading.   Maj. Op. 13-14.     The reference to the islands "in the
    [river]" running from a southward point A to a northward point B
    is easily read to be merely part and parcel of the effort, partly
    carried out by the "consisting" phrase, to demarcate the bounds of
    the area as a whole, rather than to distinguish between the land
    masses and the surrounding waters within that area.
    That leaves, then, only the majority's assertion that an
    area-based reading impermissibly requires that we give the word
    "islands" two distinct meanings in the same provision -- one
    referencing an area that includes waters and another referencing
    uplands alone.     Maj. Op. 25-26.   But, I do not see how such a
    reading does so.
    The two phrases in § 6203(8) of the MIA that use that
    same word "islands" comfortably may be understood to be working
    - 76 -
    together to specify the area comprising the "islands."               The
    "islands" referenced each time are ones that are grouped together
    in a continuous stretch of water and that are expressly referred
    to only in connection with the 1818 "agreement" that "reserved"
    them to the Nation.     The latter phrase does, on such a reading,
    demarcate the area in a way that the former on its own does not.
    But, that does not mean the latter is not referring to an area
    just as the former is.
    In   fact,   the   "excepting"   phrase   that   then   follows
    accords with this same understanding -- even though, of course, it
    does not compel it.    Unlike the phrases that contain the two prior
    references to "islands," the "excepting" phrase refers to "any
    island" that has certain specified attributes and so does not refer
    to the group of "islands" previously referenced at all.               The
    singular-form reference to "any island" in the "excepting" phrase
    thus may be read to suggest that any discrete land mass with the
    attributes denominated -- that is, any individual land mass in
    that area that had been "transferred to a person or entity other
    than a member of the Penobscot Nation subsequent to June 29, 1818,
    and prior to the effective date of this Act," 
    Me. Rev. Stat. Ann. tit. 30, § 6203
    (8) -- is being excepted from the area comprising
    the "islands" already mentioned.
    In this respect, the text admits of being read much as
    an admittedly stilted advertisement for "a tour of the U.S. Virgin
    - 77 -
    Islands, consisting solely of all those islands excepting the
    island of Saint Croix" might be.        Such an advertisement is easily
    read to suggest that the tour will be of the entirety of the
    waters-inclusive area comprising the U.S. Virgin Islands, though
    not of the one particular upland portion of it that has been
    expressly excluded.
    Finally,    I   realize   that,    as    the    majority      notes,
    § 6203(8) of the MIA was amended in 1988 to add to the definition
    of   "Penobscot    Indian    Reservation"     certain      parcels   of    land
    "acquired   by    the   Penobscot   Nation    from   Bangor   Pacific     Hydro
    Associates as compensation for flowage of reservation lands by the
    West Enfield dam."       
    1988 Me. Laws 1300
    .        I also realize that the
    majority stresses that the compensation is only for flowage and
    not for the construction of a dam on the submerged lands of the
    Main Stem, which is the part of the Penobscot River that contains
    the waters in dispute.34      Maj. Op. 30.      The District Court relied
    on this amendment too, for the distinct point that it supports
    reading § 6203(8) of the MIA to include only the uplands given
    that, if the "Reservation" included the relevant waters of the
    Main Stem, flowage would not result in the loss of reservation
    space.    See Penobscot Nation v. Mills, 
    151 F. Supp. 3d 181
    , 217
    n.42 (D. Me. 2015).
    34     The dam was built in 1894 in the Penobscot River above
    Old Town.
    - 78 -
    But, the Penobscot Nation, like anyone, has different
    uses for uplands and waters, and the loss of an upland area is
    still a loss even if the flowage remains part of the "Reservation."
    The amendment makes sense, therefore, even if § 6203(8) of the MIA
    is read to mean the relevant area as a whole -- especially given
    the limited nature of the rights to regulate hunting and trapping
    in the waters in the area at issue that the Penobscot Nation
    contends that it would enjoy, at a minimum, if the "Reservation"
    does not exclude those waters altogether.
    3.
    For all these reasons, then, the text of § 6203(8) of
    the MIA itself may be read to be making a less-than-generic
    reference   to   the   "islands"    no    less   than    the   text   in   the
    reservation-defining statute in Alaska Pacific Fisheries.                  That
    said, there are textual differences between § 6203(8) of the MIA
    and the provision at issue in Alaska Pacific Fisheries, just as
    there are textual differences between § 6203(8) of the MIA and the
    provision at issue in Hynes.
    I do not disagree that those differences supply some
    reason to hesitate before relying on those cases to find the kind
    of ambiguity here that would permit us to do what the Court did in
    each of those earlier cases:       look beyond a dictionary to history
    and context to determine what was intended.             But, as I will next
    explain, in light of the potential ambiguity in § 6203(8) of the
    - 79 -
    MIA, we cannot look to that provision alone to determine whether
    its text is ambiguous.        We must at least consider that provision's
    text in the context of the text of the other provisions of the
    Settlement Acts.          See Maj. Op. 43-45.    And, when I consider one
    such provision, § 6207(4) of the MIA, any hesitancy that I might
    have about finding § 6203(8) to be ambiguous in the relevant
    respect dissipates. For, once that provision is brought into view,
    the textual case for reading § 6203(8) to be referring to the area
    comprising the islands "reserved . . . by agreement" rather than
    only to the uplands of the islands in that area is at the very
    least strong enough to render the provision unclear as to whether
    that        area-based,    waters-inclusive     understanding    is   to   be
    preferred.
    C.
    Section 6207 of the MIA addresses the control over
    wildlife resources that the Penobscot Nation retains in Indian
    territory, including as to the part of such territory that is
    itself within the "Penobscot Indian Reservation."35             As a discrete
    provision within that larger section, § 6207(4) addresses just one
    aspect of that control.           It states that "the members of the
    35 In the Settlement Acts, Penobscot "territory" is not
    coextensive with the "Reservation." The latter refers to only the
    area set forth in § 6203(8).       The former covers both the
    "Reservation" area and a number of other areas throughout Maine.
    
    Me. Rev. Stat. Ann. tit. 30, §§ 6203
    (9), 6205(2).

    Passamaquoddy Tribe and the Penobscot Nation may take fish, within
    the boundaries of their respective Indian reservations, for their
    individual sustenance."   
    Me. Rev. Stat. Ann. tit. 30, § 6207
    (4).36
    The reason that § 6207(4) of the MIA is so significant
    for present purposes is that the "Penobscot Nation . . . Indian
    reservation[]" to which this provision refers must be understood
    -- at least when read in context -- to include the area comprising
    the islands at issue in this case, waters included, rather than
    merely the discrete uplands that are situated in that area.          See
    Maj. Op. 48-51.
    This    conclusion   follows   from   the   District   Court's
    factual finding, accepted by all parties to this appeal, that
    "[n]one of [the uplands of] those islands contains a body of water
    in which fish live."    Penobscot Nation, 151 F. Supp. 3d at 186.
    In light of that finding, an interpretation of § 6207(4) of the
    MIA that permits fishing only from the uplands is an untenable
    one. Given the "long-accepted practice of Penobscot Nation members
    sustenance fishing [from boats] in the Main Stem," id. at 220, and
    how ill-suited the uplands are to that practice, this sustenance
    fishing provision would have no practical meaning as to the
    36   With the passage of the MIA, Maine repealed a state law
    that had established "the right of Indians to take fish and
    wildlife for their own sustenance on their own reservation lands."
    
    Me. Rev. Stat. Ann. tit. 12, § 7076

    - 81 -
    Penobscot   Nation   if   the   "reservation[]"   to   which   it   refers
    encompassed only those uplands.
    But, precisely because § 6207(4) of the MIA must be so
    understood despite the ambiguities that its text alone might
    contain -- as even the majority agrees, Maj. Op. 4837 -- I do not
    37   The majority does point out that § 6207(4) refers to the
    "reservations" of the Penobscot Nation and the Passamaquoddy
    Tribe. Maj. Op. 46-47. But, the plain text of that provision
    specifically provides that members of the Penobscot Nation and the
    Passamaquoddy Tribe "may take fish[] within the boundaries of their
    respective Indian reservations."    
    Me. Rev. Stat. Ann. tit. 30, § 6207
    (4) (emphasis added). This language is much more specific
    than the similar state law provision that was repealed with the
    enactment of the MIA.       See 
    Me. Rev. Stat. Ann. tit. 12, § 7076
    (9)(B) (establishing "the right of Indians to take fish and
    wildlife for their own sustenance on their own reservation lands"
    (emphasis added)). Moreover, the legislative history makes clear
    that sustenance fishing in the Penobscot River, not merely within
    the Passamaquoddy Indian Reservation, was an issue of concern.
    See, e.g., Penobscot Nation, 151 F. Supp. 3d at 191 (citing
    discussions of salmon fishing in the Penobscot River).
    In addition to these reasons to think that § 6207(4) cannot
    be understood to have meaning only as to the Passamaquoddy Tribe,
    there is another. The majority's conclusion that the Settlement
    Acts are "coherent and consistent" if "Reservation" in § 6203(8)
    excludes waters and that term is given a consistent meaning
    throughout the Settlement Acts depends on § 6207(4) having meaning
    as applied to the Passamaquoddy Tribe. See Maj. Op. 46-47. But,
    it has such meaning only if there are areas within the
    Passamaquoddy    Indian   Reservation   where   members    of   the
    Passamaquoddy Tribe can engage in sustenance fishing. Assuming as
    the majority must for this argument about § 6207(4) that such areas
    do exist, there then becomes a fatal flaw in the majority's
    argument that "lands" in § 1722(i) of the MICSA excludes water.
    See Maj. Op. 13, 18 n.8, 44. That is because "lands" in § 1722(f),
    the identically worded MICSA provision that incorporates the MIA's
    definition of "Passamaquoddy Indian Reservation," would then have
    to refer to an area including waters. Yet, if "lands," standing
    alone, is waters-inclusive in § 1722(f), how can that same word,
    in an identical phrase, "reinforc[e]," Maj. Op. 13, a waters-
    - 82 -
    see how the text of the MIA alone makes clear that § 6203(8) of
    that same statute is referring only to the uplands and not to the
    area comprising the islands.    To so conclude, one would have to
    think it clear that the drafters of the MIA did not intend in
    referring to the "Penobscot Nation . . . Indian reservation[]" in
    § 6207(4) to have in mind the "Penobscot Indian Reservation" that
    § 6203(8) defines.   But, how could we be certain of that?       See
    Sullivan v. Stroop, 
    496 U.S. 478
    , 484 (1990) (explaining that we
    presume that "identical words used in different parts of the same
    act are intended to have the same meaning" (quoting Sorenson v.
    Sec'y of the Treasury, 
    475 U.S. 851
    , 860 (1986))).
    The majority is right, see Maj. Op. 49, that § 6203 of
    the MIA expressly states that the definitions that follow in the
    various subsections of that provision apply "unless the context
    indicates otherwise," 
    Me. Rev. Stat. Ann. tit. 30, § 6203
    .      But,
    that provision obviously does not command that every term defined
    in § 6203 of the MIA must be given a variant meaning at some point.
    Nor does the majority explain what "reservations" in
    § 6207(4) of the MIA would mean if it does not refer to the
    definitions of "Passamaquoddy Indian Reservation" and "Penobscot
    Indian Reservation" in § 6203(5) and § 6203(8), respectively.    The
    absence of any such explanation is especially conspicuous given
    excluding reading of the Settlement Acts' definition of "Penobscot
    Indian Reservation"?
    - 83 -
    that other provisions of the MIA in fact support reading "Indian
    reservation[]" in § 6207(4) to have the same meaning as "Penobscot
    Indian Reservation" in § 6203(8).38
    The principle that elephants do not hide in mouseholes
    also would appear to counsel against the conclusion that the
    drafters of the MIA chose silently to refer to the Penobscot Indian
    Reservation in two fundamentally inconsistent ways.       The term
    "Penobscot Indian Reservation" is of special importance to the
    statutory scheme, and, as we will see, sustenance fishing rights
    were central to the settlement discussions that led to the passage
    of the Settlement Acts.   It would not have gone unnoticed that the
    38   In § 6209-B of the MIA, which explains the jurisdiction
    of the Penobscot Nation Tribal Court, the statute refers to
    "[c]riminal offenses . . . committed on the Indian reservation of
    the Penobscot Nation" and to application of laws "within the
    Penobscot   Indian   reservation"    (both   without   capitalizing
    "reservation"). 
    Me. Rev. Stat. Ann. tit. 30, § 6209
    -B(1). By all
    indications, § 6209-B(1) uses "Indian reservation of the Penobscot
    Nation" and "Penobscot Indian reservation" interchangeably, and
    there is no indication that these uses of "reservation" were not
    meant to incorporate the definition at § 6203(8). Thus, § 6209-
    B(1) suggests -- especially in light of the fact that there are
    very few verbatim uses of the precise defined term "Penobscot
    Indian Reservation," which appears outside of § 6203(8) only in
    § 6205 -- that references to "reservations" in the MIA are meant
    to incorporate the definitions of "Penobscot Indian Reservation"
    and "Passamaquoddy Indian Reservation" even if they do not use
    those exact terms. Moreover, other provisions of § 6207 of the
    MIA suggest that the drafters of the Settlement Acts were not using
    "reservation" as a catch-all term, as many of its provisions refer
    to the "respective Indian territories" of the Penobscot Nation and
    Passamaquoddy Tribe, see, e.g., 
    Me. Rev. Stat. Ann. tit. 30, § 6207
    (1) (emphasis added) -- a reference that, by all indications,
    also refers to the definitions in § 6203, albeit to those for
    "Passamaquoddy Indian territory" and "Penobscot Indian territory."
    - 84 -
    same word was being used to convey such different meanings, and so
    the absence of any attempt to explain the decision to use the word
    in that nonuniform way would be surprising.            See Whitman v. Am.
    Trucking Ass'ns, 
    531 U.S. 457
    , 468 (2001); see also Gustafson v.
    Alloyd Co., 
    513 U.S. 561
    , 573 (1995) (explaining that "[t]he burden
    should be on the proponents of the view that" a term carries
    different meanings "to adduce strong textual support for that
    conclusion").39
    There is yet one more reason, though, to question the
    majority's insistence that "reservation[]" in § 6207(4) of the MIA
    cannot be referring to the "Reservation" that § 6203(8) of this
    same statute defines.          As I have emphasized, the definitional
    provision     at   § 6203(8)    of   the   MIA   explains   what    the   term
    "'Penobscot Indian Reservation' means" when used in the MIA.               
    Me. Rev. Stat. Ann. tit. 30, § 6203
    (8) (emphasis added).           In this way,
    the definition contained in that provision of the MIA serves to
    give content to the rights in the Nation's "Indian Reservation"
    that    the   statute   elsewhere    confers.     Because   the    definition
    39 I note that, by holding in the course of construing
    § 6203(8) of the MIA that the Nation has sustenance fishing rights
    under § 6207(4) of the MIA in the disputed portions of the
    Penobscot River, the majority necessarily renders moot the
    Nation's stand-alone request for a declaratory judgment to that
    exact same effect.    Accordingly, I do not join the majority's
    separate holding that we lack Article III jurisdiction on ripeness
    and standing grounds to entertain the Nation's request for such
    declaratory relief, as, in my view, there is no reason for us to
    reach that constitutional issue here. See Maj. Op. 51-55.
    - 85 -
    performs this function in the MIA, however, it is hardly evident
    that     "Penobscot        Nation . . .     Indian    reservation[]"        must     be
    understood      to    mean   something     different     and    undefined    in    the
    provision of the MIA that lays out the Nation's rights with respect
    to sustenance fishing -- § 6207(4) -- from what the Nation's
    "Indian Reservation" in § 6203(8) of that statute means when that
    term appears in other provisions of the MIA that similarly specify
    the Nation's rights.           To the contrary, it seems far more natural
    to read § 6207(4) to incorporate the definition of the "Indian
    Reservation"         set   forth    in   § 6203(8),    precisely    because        that
    definition has a purpose only once it is plugged into such rights-
    granting provisions.40
    To be clear, I am not arguing that § 6207(4) of the MIA
    "alters" the meaning of § 6203(8) of that statute.                   See Maj. Op.
    49.    I am arguing that § 6207(4) constitutes part of the statutory
    context that helps us decide the meaning of § 6203(8).
    I can see no other way to proceed.                It cannot be that we
    must set aside a provision purporting to refer to the "boundaries
    of     the[]"   "Penobscot         Nation . . .      Indian    reservation[]"        in
    40 For this same reason, the grant of sustenance fishing
    rights in § 6207(4) is in no way rendered unnecessary if the
    "Penobscot Indian Reservation" does include some waters of the
    Penobscot River. Under the MIA, the Nation's rights do not come
    from the definition of "Penobscot Indian Reservation." They come
    from provisions like § 6207(4). Otherwise, under the MIA, Maine
    maintains a large measure of regulatory authority even over areas
    within the "Reservation."
    - 86 -
    determining what another provision in the same statute, which
    expressly purports to define the boundaries of the "Penobscot
    Indian Reservation," means.
    That being so, a consideration of these two provisions
    of the MIA together would suggest, if anything, that the drafters
    of     the    Settlement     Acts     understood       the       "Penobscot   Indian
    Reservation" to be inclusive of the area comprising the islands
    named and not to consist only of the discrete -- water-less --
    uplands in that area. Only that reading harmonizes the provisions.
    But, even if we cannot be certain that reading is intended, the
    two provisions together at the very least undermine the notion
    that    § 6203(8)     of    the     MIA     clearly    adopts      an   uplands-only
    understanding of "Reservation," given that § 6207(4) of that very
    statute (as even the majority agrees) rejects such a waters-
    excluding reading of that very same word.
    D.
    The majority does make the fair point that if we are to
    look outside of § 6203(8) of the MIA to other provisions of the
    Settlement Acts for guidance about that definitional provision's
    intended meaning, then we cannot confine that review only to
    § 6207(4) of the MIA.             But, that wider review does not itself
    suggest      that   § 6203(8)     clearly        defines   the    "Reservation"   to
    include      only   the    uplands   of     the    islands   "reserved . . .      by
    agreement."
    - 87 -
    The majority emphasizes, Maj. Op. 44, that the MIA
    expressly defines "land or other natural resources" to include
    water and at other points references water rights or submerged
    land.     
    Me. Rev. Stat. Ann. tit. 30, §§ 6203
    (3), 6207; see also 
    25 U.S.C. §§ 1721
    (b)(2), 1722(b).          It thus considers the absence of
    those terms in § 6203(8) of that statute conspicuous.              But, the
    possible ambiguity in § 6203(8) that is our concern arises from
    the use of the word "islands" in the course of a larger phrase
    that refers back to what was "reserved . . . by agreement."           Thus,
    the bare reference elsewhere in the Settlement Acts to "lands" and
    "waters" fails to demonstrate that there is no such ambiguity to
    resolve.
    The majority also points to § 6205(3)(A) of the MIA,
    which states that "[f]or purposes of this section, land along and
    adjacent to the Penobscot River shall be deemed to be contiguous
    to the Penobscot Indian Reservation."          Maj. Op. 43.    On a waters-
    inclusive understanding of § 6203(8), however, that language in
    § 6205(3)(A) would still be doing useful work.                 It would be
    clarifying what it means to be "contiguous" to a river.            So, too,
    could it be making clear that lands that abut parts of the
    Penobscot    River   that   are   not   part   of   the   "Reservation"   are
    considered contiguous to the "Reservation."41
    41   The Intervenors argue that understanding "land along and
    adjacent to the Penobscot River" to include lands far away from
    - 88 -
    Finally, the majority invokes § 1723 of the MICSA, see
    Maj. Op. 32, which retroactively ratifies all "transfer[s] of land
    or natural resources located anywhere within the United States
    from, by, or on behalf of the . . . Penobscot Nation . . . or any
    of [its] members" and extinguishes aboriginal title to those lands
    or resources as of the date of any such transfer.          
    25 U.S.C. § 1723
    (a)-(b).   That provision's import, however, is limited.    It
    does not purport to extinguish aboriginal title to land not
    transferred.
    The MICSA does broadly define "transfer" to include
    any voluntary or involuntary sale, grant,
    lease,   allotment,    partition,   or   other
    conveyance; any transaction the purpose of
    which was to effect a sale, grant, lease,
    allotment, partition, or conveyance; and any
    act, event, or circumstance that resulted in
    a change in title to, possession of, dominion
    over, or control of land or natural resources.
    the "Reservation" along other stretches of the Penobscot River is
    in tension with the language in § 6205(3)(A) providing that such
    replacement lands are to be "as nearly adjacent to the parcel taken
    as practicable." But, because the reference in § 6205(3)(A) to
    "land along and adjacent to the Penobscot River" does not itself
    demarcate any particular stretch of the river, it can be understood
    as reflecting the understanding that it may not be practicable to
    acquire land that is on the bank of the stretch of the river within
    the "Reservation."     Moreover, "along and adjacent" need not
    necessarily refer to land far downriver on this understanding.
    "Adjacent" can mean "not distant" or "nearby," see Adjacent,
    Merriam-Webster     Online     Dictionary,    https://www.merriam-
    webster.com/dictionary/adjacent (last visited May 13, 2021) (first
    definition), a definition that finds support in the very language
    the Intervenors point to -- "as nearly adjacent to the parcel taken
    as practicable." Thus, "along and adjacent to the Penobscot River"
    could refer to land both along the river and close to it.
    - 89 -
    Id. § 1722(n).   In doing so, though, the provision just takes us
    back to the question of whether the relevant area here -- waters
    included, but sans uplands -- was transferred.
    In any event, there is reason to think that the state
    regulation of the river that Maine and the majority point to is
    not an "act" or "circumstance" that resulted in a "change in title
    to, possession of, dominion over, or control of" the river so as
    to effect a transfer.42   As the Penobscot Nation has pointed out,
    Maine also regulated -- and continues to regulate -- aspects of
    the uplands that are undisputedly part of the "Penobscot Indian
    Reservation."
    And, even if one were to accept that the sort of state
    regulation that the State and the Intervenors point to could effect
    a transfer, a conclusion that the river itself was subject to such
    a transfer would leave empty the grant of sustenance fishing rights
    in § 6207(4) of the MIA to the Penobscot Nation "within the
    42   The State relies on the interpretation of a similar
    transfer provision in the Rhode Island Indian Claims Settlement
    Act in Greene v. Rhode Island, 
    398 F.3d 45
    , 52 (1st Cir. 2005).
    But, as the Penobscot Nation points out, in Greene the Seaconke
    Wampanoag Tribe itself claimed to have been "dispossessed" of the
    lands at issue and does not seem to have occupied or controlled
    those lands even at the time the Union was formed. See 
    id. at 48, 50, 52
    .
    For similar reasons, Maine's arguments based on the doctrines
    of laches, acquiescence, and impossibility also fail. Maine relies
    on City of Sherrill v. Oneida Indian Nation, 
    544 U.S. 197
     (2005),
    but the lands in that case had been out of tribal control for over
    200 years. See 
    id. at 215-16
    .

    boundaries of" its "Indian reservation[]."                Thus, while the MICSA
    controls in the event of a conflict between that federal statute
    and the MIA, 
    25 U.S.C. § 1735
    (a), I see no reason why we must read
    § 1723 of the MICSA to create a conflict when it is hardly clear
    that the text of the Settlement Acts mandates that result.
    E.
    To this point, my focus has been on the four corners of
    the MICSA and the MIA.        That focus reveals in my view that it is
    at the very least far from clear on the face of the overall
    statutory scheme that the definition of the "Penobscot Indian
    Reservation" in § 6203(8) of the MIA must be read as the majority
    reads it.      But, of course, that conclusion does not resolve the
    ultimate interpretive dispute at hand.               It just highlights that
    there   is    much    interpretive   work     left   to    do   --   in   terms    of
    consulting what the history shows regarding what was understood to
    have been reserved by the "agreement" to which § 6203(8) of the
    MIA refers, both at the time of that agreement and in the run-up
    to the enactment of the Settlement Acts that make reference to it.
    I thus now move on to undertake that further work.
    II.
    In Alaska Pacific Fisheries, the Court resolved the
    ambiguity in the text there at issue by broadening the view to
    include      "[t]he    circumstances    in    which       the   reservation       was
    created," as the Court explained that these circumstances could
    - 91 -
    "shed much light on what Congress intended by 'the body of lands
    known as Annette Islands.'"        
    248 U.S. at 87-89
    .          Following that
    same interpretive approach to the textual ambiguity present here,
    I   will   consider    the   relevant     "circumstances"      in    which   the
    settlement    that    produced   these     Acts     was    forged,   as   those
    circumstances, too, may "shed much light on," 
    id. at 89
    , what the
    drafters of the Settlement Acts intended in using the words that
    they did in § 6203(8) of the MIA.
    As I will explain, at a minimum, those circumstances
    reinforce the reasons to find the relevant words in the provision
    here at least as ambiguous with respect to whether the waters at
    issue are included as a textual analysis of them suggests that
    they are.    Thus, at the very least, those circumstances support
    the application of the Indian canon in construing those words to
    resolve the ambiguity.
    But, before reviewing the circumstances leading up to
    the Acts' passage, it first helps to get certain things straight
    about which specific circumstances are relevant to the Acts' proper
    construction and how they differ in certain respects from the
    circumstances   that    mattered   most     in    Alaska   Pacific    Fisheries
    itself.
    A.
    In Alaska Pacific Fisheries, the Court explained that
    Congress, in defining that reservation as it did, was aware, among
    - 92 -
    other things, that "[t]he Indians naturally looked on the fishing
    grounds as part of the islands and proceeded on that theory in
    soliciting     the   reservation"    and     that   "[e]vidently   Congress
    intended to conform its action to their situation and needs."          
    248 U.S. at 89
    .      Many of those same circumstances are at least as
    present here, as we will see, given the Nation's historic ties to
    the river.    In fact, the relevant statutory text here, unlike that
    at issue in Alaska Pacific Fisheries, describes an area that the
    tribe has inhabited since time immemorial.
    But, as I have already explained, the relevant text does
    more than refer to a geographic feature to which the Nation has
    ties.   That statutory text also indicates that the drafters of the
    Settlement Acts intended in defining the "Reservation" to preserve
    what had been "reserved . . . by agreement" prior to the Acts'
    passage.
    Thus, the statute that contains the definition of the
    term at issue here would not only appear to direct us to consider
    what history shows regarding the Nation's past usages of the waters
    in question.     It would also appear to direct us to consider past
    understandings of what rights the Nation had reserved as to those
    waters.
    In that regard, it is important to keep in mind the
    following    understanding   in     reviewing   the   relatively   detailed
    history of the Nation's ties to the river that is set forth below:
    - 93 -
    § 6203(8) of the MIA plainly sets forth what the term "Penobscot
    Indian Reservation" "means" with reference to treaties in which
    the   Penobscot     Nation    gave     up     holdings   centuries      ago   to
    Massachusetts and then to Maine.            That is notable because those
    treaties did not themselves purport to be grants of rights from
    either of those states to the Penobscot Nation.                Those treaties
    were by their terms grants of rights to prior holdings from the
    Penobscot Nation to those other sovereigns.
    Thus, we must be wary of reading those treaties to
    establish the limits of what the Nation was reserving rather than
    to be merely specifying what it was relinquishing.               Otherwise we
    will fail to grasp just what the parties to those agreements
    understood them to have accomplished. See United States v. Winans,
    
    198 U.S. 371
    , 381 (1905) ("[T]he treaty was not a grant of rights
    to the Indians, but a grant of rights from them -- a reservation
    of those not granted.         And the form of the instrument and its
    language was adapted to that purpose."); Washington v. Wash. State
    Com. Passenger Fishing Vessel Ass'n, 
    443 U.S. 658
    , 680-81 (1979)
    (citing Winans, 
    198 U.S. at 380-81
    ); Cohen's Handbook of Federal
    Indian Law § 2.02 (Nell Jessup Newton ed., 2017) (describing the
    "reserved rights doctrine").
    It is equally important to keep in mind one more thing
    in reviewing the account of the history that follows.                 As I noted
    earlier,   the    Penobscot   Nation    does     not   argue   that    what   was
    - 94 -
    "reserved . . . by agreement" necessarily includes all forms of
    "ownership" of the waters and submerged lands of the river at
    issue.43    For example, the Nation has not, for purposes of this
    litigation, claimed a right to exclude non-tribal members from any
    of the waters of the Penobscot River or to control passage in those
    waters.    Nor would the Penobscot Nation have "exclusive control of
    the Main Stem" -- the portion of the Penobscot River that includes
    the waters in question -- as the majority suggests, Maj. Op. 35,
    if those waters were within what § 6203(8) defines to be the
    "Penobscot Indian Reservation."
    Under the Settlement Acts, the Penobscot Nation would
    have on its preferred reading of § 6203(8) of the MIA "exclusive
    authority . . .      to    promulgate    and    enact     ordinances
    regulating . . . [h]unting, trapping or other taking of wildlife"
    within the relevant area of the river, because the MIA expressly
    grants the Nation that right in its "Reservation."      See Me. Rev.
    43   The Penobscot Nation explained to the panel that in the
    proceedings before the District Court, its position was that its
    "circumscribed sustenance rights and related authorities" outlined
    in the second amended complaint "did not implicate riverbed
    ownership, but if they did, the Tribe's position was that it
    retained aboriginal title to the riverbed." The Nation explained
    that this is a "different concept than ownership" but nevertheless
    a largely semantic distinction given that "the Indians' right of
    occupancy is 'as sacred as the fee simple of the whites,'" County
    of Oneida v. Oneida Indian Nation, 
    470 U.S. 226
    , 235 (1985)
    (quoting Mitchel v. United States, 34 U.S. (9 Pet.) 711, 746
    (1835)).
    - 95 -
    Stat. Ann. tit. 30, § 6207(1)(A).44    And, violations of these and
    other tribal ordinances by tribal members within the portions of
    the Penobscot River at issue -- as well as certain criminal
    offenses committed by tribal members in these areas -- then would
    be within the exclusive jurisdiction of the Penobscot Nation
    (unless it chooses not to exercise such jurisdiction, in which
    case the state has jurisdiction), because, again, the MIA itself
    gives that measure of regulatory authority to the Nation within
    its "Reservation."   Id. §§ 6206(3), 6209-B(1).
    There is no suggestion by the Nation here, however, that
    either the MIA or the MICSA would give the Nation additional rights
    if its understanding of § 6203(8) of the MIA were controlling.
    44   Under the Settlement Acts, these ordinances must be
    "equally applicable . . . to all persons regardless of whether
    such person is a member of the [Penobscot Nation]," except that
    there may be "special provisions for the sustenance of individual
    members of the . . . Penobscot Nation." 
    Me. Rev. Stat. Ann. tit. 30, § 6207
    (1).     This regulatory authority does not include
    regulating the taking of fish except on ponds "wholly within Indian
    territory and . . . less than 10 acres in surface area." See 
    id.
    § 6207(1)(B), (3). And, notwithstanding this authority, the Maine
    Department of Inland Fisheries and Wildlife is entitled to "conduct
    fish and wildlife surveys" within the Penobscot Indian Reservation
    and in some circumstances may exercise regulatory authority to
    prevent "significant depletion of fish or wildlife stocks on lands
    or waters outside the boundaries of lands or waters subject to
    regulation by . . . the Penobscot Nation or the [Maine Indian
    Tribal-State Commission]." Id. § 6207(6).
    Section 6207(1) refers to Penobscot Indian territory, which,
    as I have explained, is broader than the "Penobscot Indian
    Reservation."   But, it is clear from the MIA that the relevant
    area of the river is within Penobscot Indian territory if and only
    if it is within the "Reservation." See id. § 6205(2).
    - 96 -
    Thus, we need to keep an eye only on the following in looking to
    the past:      Does the history suggest that those who drafted these
    Settlement Acts intended clearly to exclude all waters in the river
    from the definition of the "Penobscot Indian Reservation" in
    § 6203(8) of the MIA, such that the Penobscot Nation would not
    have the rights related to hunting, trapping, and taking wildlife
    in those waters that the MIA itself gives the Nation in that
    "Reservation"?
    B.
    I begin by canvassing the history that bears on the
    nature of the Penobscot Nation's rights in the area in question
    before the Nation purported to cede any of those rights to either
    Massachusetts or Maine.       That inquiry, which is foundational to
    any understanding of what the Nation had "reserved" over the years,
    necessarily takes us quite far back in time.
    1.
    So far as the record reveals, from time immemorial the
    Penobscot Nation has centered its domain, originally consisting of
    many thousands of acres of territory in what today is the State of
    Maine, on the Penobscot River.        S. Rep. No. 96-957, at 11 (1980);
    H.R. Rep. No. 96-1353, at 11 (1980), reprinted in 1980 U.S.C.C.A.N.
    3786,   3787    (stating   that   "[t]he    aboriginal   territory   of   the
    Penobscot Nation is centered on the Penobscot River" and its "land-
    - 97 -
    ownership orientation" is "riverine").45      In consequence, there is
    little question that the Penobscot Nation had aboriginal title to
    the lands in that area when the European colonists arrived in New
    England in the early seventeenth century.          And there is little
    question -- and certainly no contention to the contrary by the
    State of Maine in this litigation -- that such aboriginal title
    did encompass use and occupancy of the Main Stem of the Penobscot
    River and not merely land masses (individual islands, which may
    come and go over time) within it.       See County of Oneida v. Oneida
    Indian Nation, 
    470 U.S. 226
    , 233-35 (1985) (explaining that "Indian
    nations held 'aboriginal title' to lands they had inhabited from
    time immemorial" while "discovering nations held fee title to these
    lands, subject to the Indians' right of occupancy and use");
    Leavenworth, Lawrence & Galveston R.R. Co. v. United States, 
    92 U.S. 733
    , 742-43 (1875).
    Consistent with this understanding, the members of the
    Penobscot   Nation   located   their   principal   villages   along   that
    portion of the river.46        And, in turn, the river provided the
    Penobscot Nation with the main resources upon which its members
    45   The Penobscot refer to themselves as Pa'nawampske'wiak,
    or "People of where the river broadens out."
    46   The Penobscot's principal village was variously called
    Panawamskeag or Pem ta guaiusk took ("great or long River").
    - 98 -
    depended to live by way of fishing, hunting, and trapping, as well
    as a means of travel.
    The river's foundational influence on the Penobscot
    Nation    is    also   embedded    in    the     Nation's   language,   culture,
    traditions, and belief systems.                For example, Penobscot family
    names, ntútems ("totems"), reflect the creatures of the river:
    Neptune (eel), Sockalexis             (sturgeon),    Penewit (yellow perch),
    Nicola/Nicolar (otter), and Orno/Tama'hkwe (beaver).               Each family
    group also has its own district known as nzibum, meaning "my
    river."
    In   addition,   the     river    features   centrally    in   the
    Penobscot Nation's creation myths and is linked to many water-
    based totem animals, including fish.               This is articulated in its
    creation myth about Anglebému ("Guards the water"), the giant frog
    that gulped up all the water in the Penobscot River and was killed
    by Gluskábe, the Penobscot Nation's "culture hero," who then
    released the waters, rescued his "grandchildren," and settled "up
    the river."
    Thus, it is evident that the Penobscot River and its
    natural resources were "not much less necessary to the existence
    of the [Penobscot Nation] than the atmosphere they breathed."
    Winans, 
    198 U.S. at 381
    .          And so, when we consider -- as we next
    will -- the treaties that the Penobscot Nation purported to make
    with Massachusetts and Maine regarding its aboriginal holdings in
    - 99 -
    subsequent years, we must do so with this understanding of the
    nature of the Penobscot Nation's ties to the river.          It would be
    strange to construe those agreements -- and the reservations that
    the Nation made in them -- without doing so, for I can see no
    reason to interpret the terms of those agreements as if the
    Penobscot Nation were, in entering into them, as indifferent to
    preserving its sovereign rights in the river as Maine now appears
    to suggest that we must understand the Nation to have been.
    2.
    We consider first the various late seventeenth- and
    early eighteenth-century peace treaties between the Penobscot
    Nation and the British provinces.        In them, the Penobscot Nation
    and other tribes in the same general area agreed to "cease and
    forbear all acts of Hostility," acknowledged themselves as lawful
    subjects of Great Britain, and agreed to British colonists' use
    and   possession   of    the     colonists'   former   settlements   and
    properties.   See Treaty of Portsmouth, July 13, 1713, reprinted in
    Penhallow's Indian Wars 74 (Edward Wheelock ed., 1924); Dummer's
    Treaty, Dec. 15, 1725, reprinted in 3 Collections of the Maine
    Historical Society 416 (Portland, Brown Thurston 1853).
    But, notably, these treaties also "sav[ed] unto the
    Indians their own Ground," Treaty of Portsmouth, supra, at 76;
    Dummer's   Treaty,      supra,     at    417-18   ("Saving    unto   the
    Penobscot . . . all their Lands, Liberties and Properties not by
    - 100 -
    them conveyed or Sold to or Possessed by any of the English
    Subjects as aforesaid, as also the Priviledge of Fishing, Hunting,
    and Fowling as formerly.").     And, subsequent events provide some
    idea of what those reserved Penobscot "lands" were understood to
    be.
    In 1775, for example, a committee report of the third
    Provincial Congress of Massachusetts "forb[ade] any person or
    persons whatsoever[] from trespassing or making waste[] upon any
    of the lands and territories, or possessions, beginning at the
    head of the tide on Penobscot river, extending six miles on each
    side of said river, now claimed by our brethren, the Indians of
    the Penobscot tribe."    The Journals of Each Provincial Congress of
    Massachusetts in 1774 and 1775, at 371 (Boston, Dutton & Wentworth
    1838).   The report also noted the "friendship and assistance"
    offered by the Penobscot in the war with Great Britain.         Id.
    Indeed, a subsequent treaty, which Colonel John Allan of the
    Massachusetts militia negotiated with the Penobscot Nation and
    other Maine tribes on June 23, 1777, promised to the Penobscot the
    protection of their territory in exchange for their assistance in
    the Revolutionary War.     S. Rep. No. 96-957, at 11-12; H.R. Rep.
    No. 96-1353, at 11-12.    Crucially for present purposes, however,
    that treaty contained no terms that divested the Penobscot Nation
    of any of its aboriginal lands or sovereign rights and so does not
    - 101 -
    itself provide any basis for concluding that the Penobscot Nation
    had no claim to the river as of that date.
    There followed nearly twenty years later a 1796 treaty
    between representatives of the Penobscot Nation and officials from
    the State of Massachusetts (Maine still not yet being a state).
    That treaty, for the first time, did involve a putative cession of
    land by the Penobscot Nation.
    Despite the Nonintercourse Act being in effect at that
    time, this land cession was not approved by Congress.            See Trade
    and Intercourse Act of 1793, 
    1 Stat. 329
    , 330 (codified as amended
    at 
    25 U.S.C. § 177
    ) ("[N]o purchase or grant of lands, or of any
    title or claim thereto, from any Indians or nation or tribe of
    Indians, within the bounds of the United States, shall be of any
    validity in law or equity, unless the same be made by a treaty or
    convention entered into pursuant to the constitution . . . .").
    But, this agreement purported nonetheless to provide in exchange
    for "[o]ne hundred and forty nine and a half yards blue cloth for
    blankets, four hundred pounds of shot, one hundred pounds of
    Powder, thirty six hats, thirteen bushels of Salt . . . , one
    barrel of New England Rum, and one hundred bushels of corn," to be
    delivered upon signing the treaty, as well as similar specified
    items every year thereafter, "so long as [the Penobscot Nation]
    shall   continue   to   be   a   nation   and   shall   live   within   this
    Commonwealth," that the Penobscot Nation would cede a thirty-mile
    - 102 -
    tract, six miles wide, of "all the lands on both sides of the River
    Penobscot . . . excepting however, and reserving to the [Penobscot
    Nation], all the Islands in said River, above Old Town, including
    said Old Town Island, within the limits of the said thirty miles."
    Treaty Between the Penobscot and Massachusetts, Aug. 8, 1796, in
    2 Documents of American Indian Diplomacy 1094, 1094 (Vine Deloria,
    Jr. & Raymond J. DeMallie eds., 1999).
    There is no question that the Nation gave up a fair
    amount through this treaty -- seemingly for not much in return.
    But, the terms of this treaty in no sense indicate that the Nation
    was relinquishing rather than reserving its historic rights to use
    and occupancy of the river itself or its longstanding sovereign
    rights relating to hunting and fishing therein.
    Indeed,     in    June     1797,    the       then-Governor     of
    Massachusetts, Increase Sumner, reported in his executive address
    to the Massachusetts General Court (the Massachusetts Legislature)
    that   a   delegation      of   Penobscot     representatives     had    rightly
    complained to state officials of settler incursions that had
    "almost deprived [the Penobscot] of the Benefit of their Salmon
    Fishery."     Acts and Laws of the Commonwealth of Massachusetts 653
    (Boston, Young & Minns 1896) (emphasis added).                 And, consistent
    with   that    same     understanding,   in   1807,     a   delegation   of   the
    Penobscot Nation headed by its Chief, Attian Elmut, met with
    Massachusetts Governor James Sullivan to seek protection of the
    - 103 -
    Nation's fishing rights on the river next to its head village on
    Old Town.     A notetaker quoted Chief Attian as saying, "the God of
    Nature gave them their fishery, and no man without their consent
    has a right to take it from them."        Wabanaki Homeland and the New
    State of Maine:        The 1820 Journal and Plans of Survey of Joseph
    Treat   43    (Micah     A.   Pawling   ed.,   2007)    (emphasis      added).
    Thereafter,     in   1812,    following   attempts     by   multiple    other
    Penobscot Nation delegations to obtain redress for incursions upon
    these fisheries, the Massachusetts legislature responded with
    protective legislation.
    This is the history, then, that supplied the context for
    when representatives of the Penobscot Nation entered into the
    treaty with officials from Massachusetts -- Maine still not yet
    being a state in its own right -- that serves as the MIA's specific
    reference point:       the one signed on June 29, 1818.        It, too, was
    made without congressional approval and in apparent contravention
    of the Nonintercourse Act.         But, the treaty was sealed by the
    payment of four hundred dollars, in addition to "one six pound
    cannon, one swivel, fifty knives, six brass kettles, two hundred
    yards of calico, two drums, four fifes, one box pipes, three
    hundred yards of ribbon, and [the receipt of certain similar
    articles] . . . every year, so long as they shall remain a nation,
    and reside within the commonwealth of Massachusetts." 1818 Treaty,
    supra, at 253, 255.       And, in exchange for that seemingly minimal
    - 104 -
    consideration, the Penobscot Nation ceded "all the lands they
    claim, occupy and possess by any means whatever on both sides of
    the Penobscot river, and the branches thereof, above the tract of
    thirty miles in length on both sides of said river, which said
    tribe conveyed and released to said commonwealth" by the treaty of
    1796.     Id. at 253-54.
    This   treaty,   then,   purported   to   confirm   the   prior
    limited cession of lands in the 1796 treaty and to cede more lands
    "on both sides of the . . . river."        It did not, however, give any
    more of a hint that it disclaimed the Penobscot Nation's historic
    rights to the river than the earlier treaty had.            Indeed, this
    treaty expressly stipulated that reserved for the Penobscot Nation
    to "enjoy and improve" were four townships and "all the islands in
    the Penobscot river above Oldtown and including said Oldtown
    island."    Id. at 254.47
    47   The text of the 1818 treaty, unlike its predecessor, did
    specifically provide that "the citizens of [Massachusetts] shall
    have a right to pass and repass any of the rivers . . . which run
    through any of the lands hereby reserved, for the purpose of
    transporting their timber and other articles through the same."
    1818 Treaty, supra, at 255 (emphasis added). The parties dispute
    the import of this provision. According to the Penobscot Nation,
    it must refer to the Penobscot River. To the extent it does so,
    it reinforces an area-based reading given that the river does not
    "run through" any of the uplands but instead "run[s] through" the
    area comprising them, suggesting that the "lands hereby reserved"
    include that area.    For its part, the State argues that this
    language was only necessary given that in the 1818 treaty the
    Penobscot Nation also reserved the four townships (which were, as
    we will see, later ceded to Maine). The "right to pass and repass
    any of the rivers, streams, and ponds, which run through any of
    - 105 -
    Reflective     of   that   understanding,       in    a   colloquy
    thereafter in July of 1820 between representatives of the Penobscot
    Nation and officials from the new state of Maine -- once Maine had
    separated     from   Massachusetts      and    gained    statehood     and   was
    therefore to assume Massachusetts's treaty obligations -- John
    Neptune,     representing    the   Penobscot     Nation,    again      protested
    incursions into the river affecting the Penobscot Nation:                    "The
    white people take the fish in the river so they do not get up to
    us.   They take them with weirs; they take them with dip-net.                They
    are all gone before they get to us. The Indians get none." History
    of Penobscot County, Maine 593 (Cleveland, Williams, Chase & Co.
    1882). Then-Governor of Maine William King agreed that the protest
    was justified, replying that the Penobscot Nation's complaint
    would   be   "attended    to."     XVIII      Niles'    Weekly    Register    563
    (Baltimore, Franklin Press 1820).
    the lands hereby reserved," Maine argues, was an "affirmative grant
    to non-tribal members" to pass through the waters running through
    those reserved townships.    Maine does not point to any rivers
    running through those townships, much less ones that would have
    been important in timber transportation, as the record makes clear
    that the Main Stem of the Penobscot River was. But, it is true
    that per the 1818 treaty, the first reserved township "cross[ed]
    the mouth of the Mattawamkeag river."      Id. at 254.   Thus, the
    treaty provision granting a "right to pass" is not a conclusive
    indication that the 1818 treaty contemplated a reservation of the
    area comprising the islands, including their attendant waters.
    Nonetheless, the fact that the provision could still have meaning
    even if it did not refer to the waters surrounding the reserved
    uplands hardly eliminates the ambiguity that inheres in what was
    "reserved" in the 1818 treaty.
    - 106 -
    The   following      month,    on   August   17,   1820,   Penobscot
    leaders   signed   two   more    treaties.       Together,    these    treaties
    released Massachusetts from its obligations under the 1818 treaty
    and substituted the new state of Maine in its place.                  But, they
    did not suggest that the Nation was relinquishing what it had
    retained to that point.
    The 1820 treaty with Maine provided that the Penobscot
    Nation "shall have and enjoy, all the reservations made to them,
    by virtue of" the 1818 treaty while any "lands, rights, immunities
    or privileges" held by Massachusetts pursuant to the 1818 treaty
    would be transferred to Maine.           Wabanaki Homeland, supra, at 289.
    And, notably, in 1821, Neptune, after having raised concerns about
    the Penobscot Nation's fishing rights before the Nation signed the
    1820 treaty with Maine, followed up with a petition to the Maine
    Legislature in which he stated that
    [T]he waters of our Penobscot River was one of
    the greatest sources by which they obtained
    their [living] . . . . But . . . our brethren
    the white Men who live near the tide waters of
    our   River   every   year   built   so   many
    weares . . . . and killed so[ ]many of the
    fish that there is hardly any comes up the
    River where we live so that we cannot [c]atch
    enough for the use of our families . . . . We
    have asked the general Court at Boston to make
    laws to stop the white people from building
    wares and they have made Laws but they have
    done [us] no good . . . . [N]ow we ask you to
    make a Law to stop the white folks . . . .
    - 107 -
    There is no record of the Maine Legislature responding
    with protective legislation, as Massachusetts had done.            But, in
    1833, the State of Maine purchased for $50,000 from the Penobscot
    Nation -- again without the requisite federal approval for such a
    land purchase -- four townships on the banks of the Penobscot River
    that had been reserved for the Penobscot Nation's "perpetual use"
    in the prior treaties.
    3.
    There were no more "agreements" between the Penobscot
    Nation   and   the   States   of   Massachusetts   and   Maine,   and   such
    developments as occurred over the course of the next century are
    not especially clarifying with respect to the issue that is our
    concern.   But, to the extent they do shed light, they underscore
    how difficult it is to find any clear indication that the parties
    to any of the past agreements understood the Penobscot Nation to
    have given up all claims to sovereign rights in the waters at
    issue.
    The State of Maine did pass legislation over the course
    of these years that authorized the construction and operation of
    log booms, piers, and dams in the Main Stem of the Penobscot River,
    and lumber companies built lumber mills on and over parts of the
    Main Stem during that same time.          See Penobscot Nation, 151 F.
    Supp. 3d at 201-02.     It is also undisputed that this construction
    - 108 -
    happened without any lease or other grant from the Penobscot
    Nation.
    But, the record shows that the Penobscot Nation itself
    signed leases for dam and mill owners to build on some of the
    islands near Old Town.        And, those leases reserved fishing rights
    for the Nation and required that fish passages be left open.               The
    leases also specifically allowed for the grantees' use of parts of
    the river itself -- including "coves and eddies," river ledges,
    and other landmarks within the channel of the river.              Throughout
    this    period,   moreover,    the   Penobscot   continued   to   engage   in
    fishing, hunting, and trapping from the river and to pass between
    its islands on the river.
    This somewhat mixed picture of the understandings that
    prevailed following the treaties is in itself significant.             As we
    have seen, the history that led up to the forging of the last
    treaty involving the Penobscot Nation hardly supports an uplands-
    only understanding of what had been reserved to the Nation up until
    that time.    It is thus hard to see how what followed does so with
    any clarity.48
    48 The Intervenors do argue that the river (or even a right
    to use and occupancy of its waters of a sort that the Penobscot
    Nation now asserts) could not have been part of what was
    "reserved," given that -- whatever its aboriginal holdings may
    once have been -- the Nation ceded the river as early as the 1713
    treaty.   But, the history just recounted -- including the very
    fact of the later treaties -- and what it shows about the parties'
    understandings disposes of the Intervenors' argument that the 1713
    - 109 -
    C.
    In sum, the "circumstances," Alaska Pac. Fisheries, 
    248 U.S. at 87-89
    , that formed the backdrop for the Settlement Acts
    suggest at a minimum that it is plausible that Congress, Maine,
    and   the   Penobscot   Nation    understood   the   Nation   to   have
    "reserved . . .    by   agreement,"     through   the   limited    (but
    substantial) cessions of lands "on both sides of the . . . river"
    that were made, the Nation's use of the river and its historic
    sovereign rights with respect to fishing, trapping, and hunting
    therein.    See Winans, 
    198 U.S. at 381
    .    Thus, these circumstances
    support -- even if they do not compel -- an understanding of the
    phrase "islands in the Penobscot River reserved to the Penobscot
    Nation by agreement" in the MIA's definition of the "Penobscot
    Indian Reservation" that would include the area comprising the
    islands and not simply the uplands.
    Given that such an understanding results in a reading of
    § 6203(8) of the MIA that is just as inclusive of the waters in
    that area as is the "reservation[]" to which the majority agrees
    treaty can be understood to have divested the Penobscot Nation of
    all of its aboriginal holdings.
    The majority also characterizes as "disputed" the assertion
    that the Nation did not give up any rights to the river in the
    1796 and 1818 treaties. Maj. Op. 22. But, no party has argued
    that the Nation gave up rights to the river in either of those
    treaties, and the majority does not explain the source of this
    dispute or how the text of either treaty makes this point
    disputable.
    - 110 -
    that § 6207(4) of that same statute refers, I can see no reason
    why we would not then be confronted at the very least with an
    ambiguity in § 6203(8) to which the Indian canon would apply. And,
    if we were to apply that canon, we then would be required to
    construe the term that it purports to define -- "Penobscot Indian
    Reservation" -- in the waters-inclusive, area-based manner that
    the Penobscot Nation favors, with all the follow-on consequences
    that would entail under the Settlement Acts.
    In fact, for that not to be the case, either of two
    things would have to be true.         The legislative history of the
    Settlement Acts would have to compel us to conclude what the
    statutory text itself does not:         that the definition of the
    "Reservation" in § 6203(8) of the MIA was intended to encompass
    only the uplands of the islands at issue.      Or, alternatively, the
    Indian canons simply would have to have no application in this
    context.   I thus now wind up the analysis by considering each
    possibility.
    III.
    The majority does conclude, in an independent holding,
    that the legislative history in and of itself compels the uplands-
    only reading.   But, I cannot agree.
    A.
    The majority asserts that it would be odd for legislation
    purporting to settle the Maine tribes' land claims to resolve title
    - 111 -
    disputes by ratifying reservations in prior agreements without
    explaining what the reservations in those agreements were.         See
    Maj. Op. 28-37.   After all, why would the drafters have wanted to
    make   consideration     of   the   complicated   history   necessary,
    especially given that the disputes concern a navigable waterway?
    For this purpose-based reason, the majority contends that it makes
    sense to read § 6203(8) of the MIA -- to which the MICSA directs
    the reader to find the definition of "Penobscot Indian Reservation"
    -- to encompass only the uplands.      That reading, after all, lays
    to rest any disputes about what rights to the waters the Nation
    retains within the "Reservation" by making clear that no such
    waters lie within it.
    This argument disregards, however, the fact that the
    Settlement Acts were a response to potential land claims to areas
    that were "ceded" by the Maine tribes -- up to two-thirds of the
    area of what is now the State of Maine, see Passamaquoddy Tribe v.
    Maine, 
    75 F.3d 784
    , 787 (1st Cir. 1996) -- without regard to the
    Nonintercourse Act.      In other words, the dispute being settled
    was, in the main, about whether the putative treaty-based cessions
    of lands "on both sides of the Penobscot river" themselves were to
    be given legal effect.    It was not about the dispute that is front
    and center in this litigation, which concerns only whether what
    had been "reserved . . . by agreement" in the treaty making those
    - 112 -
    cessions of land included the area comprising the islands or only
    the uplands in that area.
    Thus, it is hardly implausible that the drafters thought
    it     sufficient   to    accomplish     their    chief   task    --    settling
    potentially dramatically destabilizing land claims -- to use the
    1818    agreement   between     the    Nation    and   Massachusetts     as   the
    reference point.     That agreement clearly established that land "on
    both sides of the . . . river" had not been "reserved" by the
    Nation.    See 1818 Treaty, supra, at 253-54.
    This understanding, which would take the drafters to
    have been relying on past understandings reflected in that treaty,
    is even less implausible when one considers the repeated references
    in the legislative history that reflect comfort with the notion
    that the Nation would retain sovereign rights relating to hunting
    and fishing.     Congress's final committee reports provide that the
    MICSA would extinguish the Nation's land claims resulting from the
    purported invalidity of the land transfers.             But, the reports also
    expressly describe the settlement as providing that "the Penobscot
    Nation    will   retain    as   reservations      those   lands   and   natural
    resources which were reserved to them in their treaties with
    Massachusetts and not subsequently transferred by them."                 S. Rep.
    No. 96-957, at 18 (emphasis added); H.R. Rep. No. 96-1353, at 18.
    Those committee reports further explain that the Nation will
    "retain[]    sovereign     activities,"     including     those   relating     to
    - 113 -
    hunting and fishing, under the Settlement Acts.        S. Rep. No. 96-
    957, at 15; H.R. Rep. No. 96-1353, at 15.
    It is also notable that the legislative history does not
    evidence a legislative understanding -- let alone a clear one --
    that the Nation was relinquishing those rights in the waters
    relating to hunting and fishing that it had long claimed as an
    aspect of its sovereignty.         To the   contrary, Congress heard
    testimony from members of the Penobscot Nation about the waters'
    importance, including testimony from a tribal member who relied on
    food sources from the river to feed her children, explaining that
    her son "fishes my islands," meaning that he fished from a canoe
    in the waters surrounding the islands.      And though members of the
    Penobscot Nation testifying before Congress expressed concerns
    that settlement provisions might be construed to destroy the
    Nation's   "sovereign   rights,"   in   particular   those   related   to
    hunting and fishing and the Nation's culture, the committee report
    for the MICSA called these concerns "unfounded" and emphasized
    that the hunting and fishing provisions in the MIA recognized the
    Penobscot Nation's "inherent sovereignty" and were "examples of
    expressly retained sovereign activities."      S. Rep. No. 96-957, at
    14-15; H.R. Rep. No. 96-1353, at 14-15.
    That part of the legislative history is important for
    present purposes.   As I have explained, § 6207(4) of the MIA, in
    securing sustenance fishing rights to the Penobscot Nation "within
    - 114 -
    the    boundaries"   of   its   "Indian    reservation[],"     is   plainly
    referring to the area comprising the islands in the Penobscot River
    that are the very same "islands" referenced in § 6203(8) of the
    MIA.    That being so, it is hard to see how this part of the
    legislative   history     supports   the   construction   of   § 6203(8)'s
    definition of the "Reservation"'s boundaries, landlocked as it
    would make them, that Maine urges us to adopt.
    But, the case for rejecting Maine's position regarding
    the legislative history is even stronger when one considers what
    that history most conspicuously does not disclose -- any suggestion
    whatsoever that the "reservation[]" referenced in § 6207(4) of the
    MIA is not the "Penobscot Indian Reservation" defined in § 6203(8)
    of that same statute.     That is quite an omission if -- in order to
    clarify things in the face of title disputes -- the legislature
    must have intended for the latter definition to be an uplands-only
    one and the former to be a waters-inclusive one.
    The omission becomes all the harder to explain -- if one
    accepts the majority's view of the definition in § 6203(8) of the
    MIA -- when one considers still other features of the legislative
    history. Those features underscore the reasons that I have already
    given to doubt that the drafters of the MIA meant to refer to two
    distinct Penobscot Nation reservations rather than merely one in
    two different provisions of that statute.
    - 115 -
    For example, in a public hearing held by the Maine
    Legislature's Joint Select Committee on Indian Land Claims in March
    1980, the tribes' attorney explained that the exercise of "tribal
    powers in certain areas of particular cultural importance such as
    hunting and fishing" was an issue that had been important for the
    State to understand in negotiations.     See Hearing on L.D. 2037
    Before the Joint Select Comm. on Indian Land Claims, 109th Leg.,
    2d Sess. 25 (Me. 1980). The Committee heard concerns about hunting
    and fishing from non-tribal members, too. A member of the Atlantic
    Seamen's Salmon Commission expressed concern that "critical parts
    of the Penobscot River" would "fall within the confines of the
    Settlement," which "could spell danger to the salmon."      Id. at
    117-18.   But, significantly, rather than refuting this premise,
    Maine's Deputy Attorney General explained:
    Currently under Maine Law, the Indians can
    hunt and fish on their existing reservation
    for their own sustenance without regulation of
    the State.    That's a right which the State
    gave   to   the   Maine   Indians   on   their
    reservations a number of years ago and the
    contemplation of this draft was to keep in
    place that same kind of right . . . .
    Id. at 55-56 (emphases added).
    It is also worth noting that those aspects of the
    legislative history suggesting that the Penobscot Nation did not
    have fee title to the submerged lands are not inconsistent with
    the idea that the Settlement Acts codified the use- and occupancy-
    - 116 -
    based hunting and fishing rights that the Penobscot Nation had
    long enjoyed, which are all the Nation must establish that it
    reserved to prevail in the present litigation.                 See Winans, 
    198 U.S. at 381
    ; Cohen's Handbook § 18.01 (explaining that aboriginal
    title    includes   "component     hunting,        fishing,     and     gathering
    rights"); id. § 15.02 ("An Indian reservation is a place within
    which a tribe may exercise tribal powers, but not all land within
    a reservation may belong to the tribe.").               And, according to the
    Penobscot    Nation's     negotiators,       the    Penobscot     Nation      had
    maintained through the negotiations that it retained aboriginal
    title to the waters of the Main Stem in the area comprising the
    islands referenced in § 6203(8).
    True,   the   stated    purposes       of    the    MICSA    include
    "remov[ing] the cloud on the titles to land in the State of Maine
    resulting from Indian claims" and "clarify[ing] the status of other
    land and natural resources in the State of Maine."                    
    25 U.S.C. § 1721
    (b).    True as well, the U.S. Department of the Interior's
    Federal Register notice describes the MICSA as "extinguish[ing]
    any claims of aboriginal title of the Maine Indians anywhere in
    the United States and bar[ring] all claims based on such title."
    Extinguishment of Indian Claims, 
    46 Fed. Reg. 2390
    , 2391 (Jan. 9,
    1981).
    But, as I have explained -- and as the extensive history
    that I have reviewed makes clear -- the Settlement Acts responded
    - 117 -
    to aboriginal title claims to the land that was ceded in the
    eighteenth- and nineteenth-century agreements.            See 
    25 U.S.C. § 1721
    (a)(1).     There is no indication that the Settlement Acts
    were intended to upset use- and occupancy-based sovereign rights
    in those areas not previously ceded in the suspect agreements --
    at least insofar as those rights are no broader than the ones
    recognized in the Settlement Acts themselves as ones that the
    Nation would retain in its "Reservation."         To the contrary, the
    focus in the federal legislative history on the Penobscot Nation's
    retained sovereignty with respect to activities that could only
    occur within the waters in question -- such as, for example, the
    activity that is the subject of § 6207(4) itself -- suggests that
    upsetting those rights was not the intended result.
    The rights that the Penobscot Nation claims, moreover,
    are a function of the substantive provisions of the Settlement
    Acts themselves.    The federal legislative history just canvassed
    shows that these provisions of those Acts -- which ensure that the
    Penobscot Nation can exercise within its "Reservation" the rights
    related to the taking of wildlife that it claims in this litigation
    -- are best understood as encompassing the area in which the Nation
    has long exercised these rights.
    Thus,    the   legislative   history   does   not   support   the
    purpose-based assertion that the majority makes about why the
    definition of "Penobscot Indian Reservation" in § 6203(8) of the
    - 118 -
    MIA must be construed to exclude altogether everything but the
    uplands.      Rather,   that   legislative   history   at   most   merely
    underscores the ambiguity that arises from the reference in that
    provision to what was "reserved . . . by agreement," given the
    waters-inclusive reference to the "Penobscot Nation . . . Indian
    reservation[]" in § 6207(4) of that same statute.
    In sum, a purpose to clear title to lands and natural
    resources that have been transferred cannot itself reveal what was
    understood to have been transferred, and the Penobscot Nation seeks
    here only to ensure that the Nation will enjoy the same sovereign
    rights over taking wildlife in the waters in question that the
    Settlement Acts plainly give the Nation throughout the Penobscot
    Indian Reservation.     I thus do not see how a recognition of those
    limited rights can be said to be beyond the comprehension of the
    drafters of these measures when the legislative history reveals
    the repeated contemplation of just such recognition.
    B.
    The majority does also conclude, less generally, that
    the legislative history shows that the legislature deliberately
    included only the uplands of the islands in the "Reservation."
    See Maj. Op. 35 n.17.    But, here, too, the evidence is weaker than
    advertised.
    In a "background" paper that the U.S. Department of the
    Interior included in a hearing submission to the House Committee
    - 119 -
    on Interior and Insular Affairs, the Penobscot Nation was described
    as having a "4,000 acre reservation on a hundred islands in the
    Penobscot River."              Had the entire Main Stem been included, bank-
    to-bank, the majority concludes, the reservation would be 13,760
    acres.    Maj. Op. 35 n.17.
    In support of its contention that this point is a salient
    one, the State cites Idaho v. United States, 
    533 U.S. 262
     (2001).
    There,    the    Court         used     as   evidence    of   the    intent    to   include
    submerged       lands         in   a   reservation      the   fact   that     the   acreage
    description          in   a    government      survey    purporting     to     define   the
    reservation's total area "necessarily included" submerged lands.
    
    Id. at 267, 274
    .               As the Penobscot Nation and the United States
    point out, however, citing examples from the website for the Maine
    Department of Inland Fisheries and Wildlife, "it is not unusual to
    specify only upland acreage when adjacent submerged lands also are
    within the boundaries."                 Therefore, there is a weaker inference to
    be drawn from an acreage description that excludes submerged lands
    than from one that necessarily includes submerged lands.                            Cf. 
    id. at 267
    .     Moreover, in Idaho the acreage description came from a
    formal survey of the reservation that was undertaken by the United
    States for the very purpose of setting the reservation boundaries
    and "fix[ing] the reservation's total area."                            
    Id.
         The brief
    reference       to    acreage          included   in    the   hearing   submission,      in
    - 120 -
    contrast, cannot bear the weight the majority or the State would
    put on it.
    Similarly, a map was provided to the Senate in the run-
    up to the MICSA's enactment that shaded only the islands and not
    the river in the color denoting the "Reservation."49        But, that map
    was introduced into the record for purposes of identifying the
    newly acquired trust lands under the settlement, not to define the
    boundaries of the existing reservation.          See Proposed Settlement
    of Maine Indian Land Claims:           Hearing on S. 2829 Before the S.
    Select Comm. on Indian Affairs, 96th Cong. 282 (1980) (statement
    of Sen. William S. Cohen, Member, S. Comm. on Indian Affairs)
    (requesting a "map of the State of Maine designating the areas
    that are now under consideration for sale" and stating that such
    a map "should become a part of the record as far as what areas are
    being contemplated for sale and what range of parcels are being
    contemplated for purchase").      Particularly in these circumstances,
    the     shading   hardly   indicates    that   Congress   understood   the
    Penobscot Nation to retain no reservation-based rights in the Main
    Stem.
    49  The District Court found that pursuant to the map's key,
    the islands in the Main Stem were shaded in red, which represented
    "Indian Reservation," and the Main Stem was shaded in white, which
    represented "river and lakes adjacent to settlement lands."

    The    post-enactment       history   of   the    Settlement   Acts
    reinforces this same understanding. It cannot reveal a legislative
    meaning not otherwise indicated, but it does usefully give some
    indication of the understandings that prevailed at the time of the
    Settlement Acts' passage.        Those understandings comport with the
    understanding of the "Reservation" boundaries that the Penobscot
    Nation favors.       See Alaska Pac. Fisheries,

    the public as reserving the adjacent fishing grounds as well as

    Consider that the Penobscot Nation began operating its
    own warden service in 1976, Penobscot Nation, 151 F. Supp. 3d at
    196-97, largely through federal funding from the U.S. Department
    of the Interior for the Nation's exercise of governmental authority
    on   "Reservation      lands   and     waterways,"50   and   that   the    Nation
    continued doing so after the Settlement Acts were enacted.                    In
    fact,      since   1982,   Penobscot    Nation   wardens     have   been   cross-
    deputized under state law to "have the powers of [state] game
    wardens" within "Penobscot Indian Territory."              
    Me. Rev. Stat. Ann. tit. 12, § 10401
    ; 
    1981 Me. Laws 1886
    , 1887; see also Penobscot
    Nation, 151 F. Supp. 3d at 197.
    To be sure, in the years following the Settlement Acts,
    Maine and Penobscot Nation game wardens collaborated on some
    patrols and enforcement actions in the Main Stem.                     Penobscot
    Nation, 151 F. Supp. 3d at 197.           According to affidavits of state
    game wardens, those wardens enforced Maine fish and game laws
    50  The Penobscot Nation has consistently received federal
    funding related to the river. For example, in 1993, the Penobscot
    Nation received funding for a water resources management program
    that included monitoring of the Penobscot River. Penobscot Nation,
    151 F. Supp. 3d at 212. In 1999, the Nation received funding to
    educate tribal members on the risks of consuming contaminated fish,
    in light of the fact that tribal members continued to rely on the
    river to feed their families. Id. And, in 2007 and 2010, the
    Nation   again   received   funding   for  game   warden   patrols,
    acknowledging that the tribe patrolled in the Penobscot River.
    Id.
    - 123 -
    against tribal and non-tribal members.      But, the record shows, in
    1990, when state game wardens responded to a report involving a
    tribal member deer hunting from a boat in the Penobscot River in
    violation    of   state   hunting   regulations,   the   state   wardens
    contacted Penobscot Nation wardens, and the tribal member was
    ultimately turned over to Penobscot Nation wardens for prosecution
    in the Tribal Court after an initial joint investigation.51          See
    id. at 209.       Thus, this aspect of the post-enactment history
    accords with a conclusion that the Settlement Acts were not
    understood to have conferred to Maine full authority with respect
    to hunting, trapping, and fishing in the relevant waters, such
    that the Nation was divested of them.
    2.
    Other post-enactment developments and representations by
    state officials support this same conclusion.       For example, eight
    years after the Settlement Acts were negotiated and went into
    effect, an issue arose as to the application within the river of
    state-wide rules against the use of gill nets to harvest fish.
    See id. at 199.      Members of the Penobscot Nation wanted to use
    51   The Penobscot Nation's exercise of jurisdiction suggests
    that the river was understood to be within the "Reservation" in
    part because the Settlement Acts gave the Penobscot Nation
    exclusive jurisdiction over certain criminal offenses committed on
    the Penobscot Indian Reservation by a tribal member. The Tribal
    Court would not have had jurisdiction over a crime not committed
    on its reservation. See 
    1989 Me. Laws 249

    1979 Me. Laws 2404

    gill   nets    to    fish      in   the   Penobscot    River,     within   what   they
    understood to be part of the "Reservation," as was consistent with
    the Nation's traditional practices and permitted under its own
    regulations.
    In a letter dated February 16, 1988, Maine Attorney
    General James E. Tierney opined that the Penobscot Nation's use of
    gill nets was permissible:
    In the opinion of this Department, . . .
    [p]ursuant to Section 6207(4) of the [MIA],
    members of the . . . Penobscot Nation are
    authorized to take fish, within the boundaries
    of their . . . Indian Reservation[], and
    "notwithstanding any rule or regulation
    promulgated by the Commission or any other law
    of the State," so long as the fish so taken
    are used for "their individual sustenance."
    Letter from James E. Tierney, Att'y Gen. of Me., to William J.
    Vail, Chairman, Atl. Sea Run Salmon Comm'n (Feb. 16, 1988).                       There
    was notably no indication in this response that the "Indian
    Reservation[]" to which he referred was not the one defined in
    § 6203(8).     Indeed, the capitalized reference to the "Reservation"
    appears to reflect the understanding that they were the same.
    Similarly, in the mid-1990s, Maine issued permits for
    eel pots in waters of the Penobscot River that provided that "[t]he
    portions of the Penobscot River and submerged lands surrounding
    the    islands      in   the    river     are   part   of   the   Penobscot   Indian
    Reservation and [gear] should not be placed on these lands without
    permission from the Penobscot Nation."                  Penobscot Nation, 151 F.
    - 125 -
    Supp. 3d at 199.    Again, it is hardly logical to think that this
    reference to the "Penobscot Indian Reservation" meant something
    different than that term as defined in § 6203(8) of the MIA.
    In fact, the Penobscot Nation maintained in the years
    following the Settlement Acts its own permitting system and issued
    permits to non-tribal members for duck hunting and eel trapping in
    the relevant waters.   And, the Penobscot Nation passed regulations
    concerning tribal members' sustenance fishing in those waters.52
    Illuminating, too, are the disputes that arose in the
    1990s over the relicensing of hydro-electric dams on the Penobscot
    River.    In   proceedings    before    the    Federal   Energy   Regulatory
    Commission ("FERC"), Bangor Pacific Hydro Associates and various
    papermaking companies with facilities located in or near the river
    asserted the position that the river was outside the reservation
    boundaries.      Then-Chair    of      the    Maine   Indian   Tribal-State
    Commission Bennett Katz, who was Majority Leader of the Maine
    Senate at the time of the MIA's passage, explained in a letter to
    FERC that this was "the first time these particular arguments ha[d]
    come to the attention of the Commission" and that, "[t]o [his]
    knowledge, the State ha[d] never questioned the existence of the
    right of the Penobscot Indian Nation to sustenance fishing in the

    Nation is not seeking here to regulate fishing other than tribal
    members' sustenance fishing.

    Penobscot River."         Letter from Bennett Katz, Chair, Me. Indian
    Tribal-State Comm'n, to Lois Cashell, Sec'y, Fed. Energy Regul.
    Comm'n (Nov. 1, 1995).         Moreover, he stated that he could not
    "imagine that [such a restrictive] meaning was intended by [his]
    colleagues    in    the   Legislature      who   voted   in   support    of   the
    Settlement."       Id.
    Indeed, the State of Maine subsequently expressed its
    view in a brief to FERC that "Penobscot fishing rights under the
    [MIA] exist in that portion of the Penobscot River which falls
    within the boundaries of the Penobscot Indian Reservation," which
    "may generally be described as including the islands in the
    Penobscot River above Old Town . . . and a portion of the riverbed
    between any reservation island and the opposite shore."                 State of
    Maine's Response to the Department of the Interior's April 9, 1997
    Filings Pursuant to Sections 4(e) and 10(e) of the Federal Power
    Act at 12-13, Project No. 2534 (FERC May 29, 1997).                So, there,
    too,   the   equation     between   the    "reservation[]"     referenced      in
    § 6207(4) of the MIA and the "Reservation" referenced in § 6203(8)
    of that statute seemed to be one that came naturally even to Maine
    itself.
    3.
    There is still more evidence from these years that it
    was not thought that the Settlement Acts defined an uplands-only
    "Reservation."       Also in the 1990s, the Penobscot Nation began
    - 127 -
    lobbying the U.S. Environmental Protection Agency ("EPA") for
    water quality standards that would protect the Nation's right to
    sustenance fish in the Main Stem.        Penobscot Nation, 151 F. Supp.
    3d at 207.    Maine's Attorney General wrote to the EPA asserting
    that the sustenance fishing rights established in the Settlement
    Acts did "not guarantee a particular quality or quantity of fish."
    Letter from Andrew Ketterer, Att'y Gen. of Me., to John DeVillars,
    Reg'l Adm'r, Env't Prot. Agency (June 3, 1997).          But, notably, in
    the course of that letter, he did not reject the view that the
    Nation had rights in the waters owing to its rights to the islands,
    stating that "[a]lthough there may be a certain portion of the
    river bed that goes along with the ownership of an island in the
    river, . . . ownership of a portion of the bed does not constitute
    ownership of the 'river.'"       Id.
    There is, finally, a 2006 brief to this Court involving
    Maine's environmental regulatory authority concerning discharges
    into the river.      Maine acknowledged there that there was "strong[]
    disagree[ment]" between the parties -- the State, the Penobscot
    and Passamaquoddy Tribes, and the federal government -- concerning
    the "boundaries of Indian Territory in the Penobscot basin." Brief
    of Petitioner State of Maine at 58, Johnson, 
    498 F.3d 37
     (Nos. 04-
    1363, 04-1375). But, in that same litigation, the State made clear
    that   it   viewed    the   definition   of   the   "Reservation"   in   the
    Settlement Acts as including the "accompanying riparian rights" to
    - 128 -
    the islands that "have not been transferred."             Brief of State of
    Maine as Intervenor-Respondent at 3 n.2, Johnson, 
    498 F.3d 37
     (Nos.
    04-1363, 04-1375).     This statement, though not a concession of the
    point in dispute here, is also in no sense a clear embrace of the
    uplands-only view now said to be crystal clear in § 6203(8).
    In fact, it was only when, around 2012, the Maine
    Commissioner of Inland Fisheries and Wildlife and the Colonel of
    Maine's Warden Service requested an opinion from the Maine Attorney
    General addressing the "respective regulatory jurisdictions" of
    the Penobscot Nation and the State "relating to hunting and fishing
    on the main stem of the Penobscot River" that the uplands-only
    view became Maine's in any clear way.           Att'y Gen. of Me., Opinion
    Letter (Aug. 8, 2012).      In a formal opinion issued on August 8,
    2012,   Maine   Attorney   General      William     Schneider   adopted    the
    interpretation of the MIA that Maine had previously disavowed when
    it was proposed by the paper companies in the FERC proceedings --
    that "the River itself is not part of the Penobscot Nation's
    Reservation,    and   therefore   is    not    subject   to   its   regulatory
    authority or proprietary control."            Id.
    D.
    In sum, neither the text of the Settlement Acts nor their
    pre- or post-enactment history requires the conclusion that the
    definition of the term "Penobscot Indian Reservation" in the
    Settlement Acts unambiguously excludes the waters at issue, such
    - 129 -
    that the rights in the "Reservation" under the Settlement Acts
    themselves that are actually at issue in this case do not extend
    to those waters.         It is hardly unambiguous, therefore, that the
    Settlement Acts' definition of "Penobscot Indian Reservation"
    excludes the waters at issue, such that the Nation's sole right in
    them is conferred by § 6207(4) and that the Nation has no rights
    in them in consequence of what was "reserved to the Penobscot
    Nation by agreement."        For, as I have explained, "islands in the
    Penobscot River reserved to the Penobscot Nation by agreement" is
    not   itself   a   term     with    a   fixed    and    readily   identifiable
    geopolitical meaning.       See Amoco Prod. Co., 
    480 U.S. at
    547 & n.14.
    And, as the Supreme Court has made clear, the use of terms like
    "lands" and "islands" in a larger phrase does not, depending on
    context, necessarily exclude attendant waters.               See, e.g., Alaska
    Pac. Fisheries, 
    248 U.S. at 89
    ; Hynes, 
    337 U.S. at 110-11
    .
    IV.
    The Penobscot Nation urges us, not unpersuasively, to
    conclude   that    the    history   (legislative       and   otherwise)   itself
    suffices to demonstrate that its reading of § 6203(8) of the MIA
    -- given the ambiguity inherent in that provision's text and the
    text of § 6207(4) of that same statute -- is superior.                But, the
    Nation recognizes that we need not do so for it to win.
    "When     we      are    faced       with . . .      two   possible
    constructions, our choice between them must be dictated by a
    - 130 -
    principle       deeply     rooted      in . . .       Indian      jurisprudence:
    '[S]tatutes are to be construed liberally in favor of the Indians,
    with ambiguous provisions interpreted to their benefit.'"                 County
    of Yakima, 
    502 U.S. at 269
     (third alteration in original) (quoting
    Montana v. Blackfeet Tribe of Indians, 
    471 U.S. 759
    , 766 (1985));
    see also Antoine v. Washington, 
    420 U.S. 194
    , 199 (1975) ("The
    canon of construction applied over a century and a half by this
    Court is that the wording of treaties and statutes ratifying
    agreements with the Indians is not to be construed to their
    prejudice.").        Thus, the Nation contends, and I agree, that the
    canon itself suffices to resolve this case in the Nation's favor.
    Maine does argue that the Indian canons cannot apply
    here,    even   if   the   relevant    statutory      provision    defining   the
    "Reservation" is not itself clear.            But, in light of this Court's
    opinion in Penobscot Nation v. Fellencer, 
    164 F.3d 706
     (1st Cir.
    1999), I cannot agree.             See 
    id. at 709
     (construing the phrase
    "internal tribal matters" in the MIA and noting that it is a
    "general principle[] that inform[s] our analysis of the statutory

    tribes . . . strictly,' 'with ambiguous provisions interpreted to

    the Rhode Island Indian Claims Settlement Act and its enacting

    benefit     of    any   ambiguity    on     the    waiver-abrogation         issue");

    disadvantage" because the Supreme Court has applied the Indian
    canon     even    "where   Indians   were    at     no    legal    disadvantage").53
    53   Maine and the Intervenors argue that specific provisions
    of the MICSA providing that "no law or regulation of the United
    States (1) which accords or relates to a special status or right
    of or to any Indian, Indian nation . . . [or] Indian lands . . . ,
    and also (2) which affects or preempts the civil, criminal, or
    regulatory jurisdiction of the State of Maine . . . shall apply
    within the State" preclude application of the canon of
    construction.    
    25 U.S.C. § 1725
    (h); see also 
    id.
     § 1735(b)
    (providing that "[t]he provisions of any Federal law enacted after
    October 10, 1980, for the benefit of Indians, Indian nations, or
    tribes or bands of Indians, . . . which would affect or preempt
    the application of the laws of the State of Maine . . . shall not
    apply within the State of Maine" unless specifically provided).
    Even assuming that Fellencer did not resolve this issue, the claim
    is unavailing.   The Senate Report supports the view that these
    provisions apply to statutes enacted and rules promulgated and not
    to interpretive principles.     See S. Rep. No. 96-957, at 30-31
    (citing as examples the Indian Child Welfare Act and the federal
    Clean Air Act). Moreover, the MICSA's baseline is that "the laws
    and regulations of the United States which are generally applicable
    to Indians . . . shall be applicable in the State of Maine." 
    25 U.S.C. § 1725
    (h). Although Maine argues that the case "has direct
    jurisdictional implications for the State" and that applying the
    canons would affect Maine's "jurisdiction" -- a term that the
    - 132 -
    Indeed, the majority does not dispute that the canon would apply
    in the event of an ambiguity.      See Maj. Op. 39-40.
    Nor do Maine's and the Intervenors' arguments that, even
    if the Indian canon does apply, the canon against conveying
    navigable waters must take precedence over it change the result
    here.      Even if the navigable waters canon could apply to the
    circumstances here, where the federal government never held title
    to the river in trust for a state, there is no apparent tension
    between the idea that the state could hold "title" in the manner
    contemplated by the navigable waters canon and the notion that at
    the same time the Penobscot Nation has what it claims here:         use-
    and   occupancy-based   rights.     Thus,   as   an   ambiguity-resolving
    principle, the navigable waters canon can do little work here.54
    Senate Report suggests is to be "broadly construed," S. Rep. No.
    96-957, at 30 -- there is a difference between an interpretive
    principle that could result in jurisdictional implications and
    statutes that control how state jurisdiction applies in Indian
    country. Nothing in the legislative history clearly reaches the
    former as opposed to merely the latter. The reference to Bryan v.
    Itasca County, 
    426 U.S. 373
     (1976), in the Senate Report is no
    different. It makes clear that the MICSA's reference to "civil
    jurisdiction" should not be construed to mean only jurisdiction
    over private civil litigation (i.e., adjudicative jurisdiction)
    but could also include the state's legislative jurisdiction. But,
    it does not speak to whether interpretive canons fall within
    § 1725(h) of the MICSA.
    54  To the extent Maine and the Intervenors make a separate
    argument that states presumptively gain title to beds of navigable
    waters upon statehood, see, e.g., United States v. Holt State Bank,
    
    270 U.S. 49
    , 54-55 (1926); Idaho v. Coeur d'Alene Tribe, 
    521 U.S. 261
    , 283-84 (1997), and thus that by the time the treaties were
    signed the Penobscot Nation no longer had any rights in the waters
    to reserve, there is no reason to think the drafters of the
    - 133 -
    The Indian canon, in contrast, is responsive to the
    interpretive question that we are left with. This canon is "rooted
    in the unique trust relationship between the United States and the

    164 F.3d at 709
     (quoting County of Oneida,
    
    470 U.S. at 247
    ), and that relationship applies here, see Joint
    Tribal Council of the Passamaquoddy Tribe v. Morton, 
    528 F.2d 370
    ,
    373 (1st Cir. 1975).      There is, moreover, especially good reason
    to think that a construction in the Nation's favor is in fact a
    fair   proxy   for   Congress's   intent,   given   the   particular   role
    Settlement Acts incorporated the understanding that what was
    "reserved" never could have included the river for this reason and
    thus intended § 6203(8) of the MIA to refer only to uplands. Even
    if one thought there was some legal reason that the Nation could
    not have reserved rights in an area that included the waters in
    the treaties, notwithstanding an intent on the part of the treaty
    parties to permit the Nation to make such a reservation, the better
    understanding of the Settlement Acts is that Congress meant to
    incorporate the understanding of the treaty parties at the time.
    And, as I have noted, the evidence from the history shows that the
    treaty parties understood what had been reserved by the Nation at
    each juncture to include rights in waters and fisheries.         In
    addition, the 1818 treaty itself granted to citizens of the
    Commonwealth the "right to pass and repass any of the rivers,
    streams, and ponds, which run through any of the lands hereby
    reserved, for the purpose of transporting their timber and other
    articles through the same." 1818 Treaty, supra, at 255. Whether
    or not that portion of the treaty refers to the Penobscot River,
    it at the least demonstrates that it was not the parties'
    understanding that the Penobscot Nation had no claim to any such
    navigable waters once Massachusetts became a state.           Thus,
    especially when § 6207(4) of the MIA is brought into view, Maine
    and the Intervenors' contention about states presumptively gaining
    title to the beds of navigable waters upon statehood does nothing
    to clear up the ambiguity in the text that is plainly there and
    thus does nothing to preclude the application of the Indian canon.

    Congress was playing in settling these land claims in the face of
    assertions that the Nonintercourse Act had been violated.
    V.
    Notwithstanding      the   differences        between   Congress's
    reference to the "body of lands known as Annette Islands" in the
    statute at issue in Alaska Pacific Fisheries and the Settlement
    Acts' way of referring to these islands here, this much is -- at
    the very least -- clear:       § 6203(8) of the MIA does not compel an
    uplands-only reading, whether it is considered in the context of
    the   Settlement   Acts   as   a   whole     or   in   the   context   of   the
    circumstances that led to their enactment.             We thus are obliged to
    resolve the ambiguity in the Penobscot Nation's favor.             For, while
    the Settlement Acts confirm that the Penobscot Nation gave up any
    claim (aboriginal or otherwise) to the lands with which they had
    parted through earlier treaties made without the required federal
    authorization, I cannot see how we could say that it is equally
    plain that the text of those Acts also confirms that the Acts do
    not protect the Penobscot Nation's historic rights to the area
    comprising the islands that the Nation now claims in this appeal.
    Before we conclude that a statute purporting to honor what this
    riverine Nation had "reserved . . . by agreement" in fact deprives
    it of the sovereign rights that it had long enjoyed in the river
    that defines it, we must have a clearer indication than is present
    - 135 -
    here that the statute was intended to have such a dramatic and
    potentially devastating consequence.
    Accordingly, I respectfully dissent.
