    SUMMARY*
    Fed. R. Civ. P. 19 / Tribal Immunity
    The panel reversed the district court’s summary judgment
    in favor of Portland General Electric (PGE) and the
    Confederated Tribes of the Warm Springs Reservation of
    Oregon (the Tribe), and remanded with instructions to vacate
    the judgment and to dismiss a citizen suit in which Deschutes
    River Alliance (DRA) alleged that PGE was operating the
    Pelton Round Butte Hydroelectric Project (the Project) in
    violation of the Clean Water Act (CWA).
    PGE and the Tribe co-own and co-operate the Project on
    the Deschutes River, located partly within the Warm Springs
    Indian Reservation in Oregon. The district court denied
    PGE’s motion under Fed. R. Civ. P. 19 to dismiss for failure
    to join the Tribe as a required party, holding that the Tribe
    was a required party but feasible to join because the CWA
    had abrogated the Tribe’s sovereign immunity. DRA filed an
    amended complaint joining the Tribe as an additional
    defendant. The district court held that the Project was not in

    violation of the CWA and granted summary judgment in
    favor of PGE and the Tribe.
    The panel held that DRA has Article III standing.
    The panel held that the Tribe did not waive its sovereign
    immunity to this suit. The panel wrote that the Tribe’s waiver
    of its immunity when it agreed not to assert sovereign
    immunity from a suit brought by a party to the Project’s
    Implementation Agreement does not apply to a suit brought
    by DRA, which is not a party to the Agreement.
    The panel held that the CWA did not abrogate the Tribe’s
    sovereign immunity. The panel wrote that the inclusion of
    “an Indian tribe” in the definition of “municipality” in
    33 U.S.C. § 1362(4) (and, in turn, the definition of “person”
    in 33 U.S.C. § 1362(5)) does not indicate—let alone clearly
    indicate—that Congress intended in the CWA to subject
    tribes to unconsented suits.
    The panel held that the Tribe is a required party under
    Fed. R. Civ. P. 19(a)(1)(B)(i) because it has a legally
    protected interest in the subject of the suit that may be
    impaired by proceedings conducted in its absence, but that
    joinder of the Tribe is infeasible because of its Tribal
    immunity. Noting that PGE and the Tribe have potentially
    divergent interests, the panel determined under Fed. R. Civ.
    P. 19(b) that the case cannot proceed in the Tribe’s absence.
    The panel therefore concluded that DRA’s suit must be
    dismissed under Rule 19 for failure to join a required party.
    Dissenting in part and concurring in the judgment, Judge
    Bea joined the majority in most of its holdings, including that
    the text of the CWA does not evince Congress’s clear intent
    DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC.            5
    to abrogate tribal immunity. He wrote that the Opinion’s
    references to the legislative history of the CWA as additional
    support for its determination are superfluous and irrelevant.

    OPINION
    W. FLETCHER, Circuit Judge:
    Portland General Electric (“PGE”) and the Confederated
    Tribes of the Warm Springs Reservation of Oregon (the
    “Tribe”) co-own and co-operate the Pelton Round Butte
    Hydroelectric Project (the “Project”) on the Deschutes River,
    located partly within the Warm Springs Indian Reservation in
    Oregon. Deschutes River Alliance (“DRA”) filed a citizen
    suit against PGE alleging that PGE was operating the Project
    in violation of the Clean Water Act (“CWA”). See 33 U.S.C.
    § 1365.
    PGE moved under Federal Rule of Civil Procedure 19 to
    dismiss for failure to join the Tribe as a required party. The
    district court denied the motion, holding that the Tribe was a
    required party but feasible to join because the CWA had
    abrogated the Tribe’s sovereign immunity. DRA filed an
    amended complaint joining the Tribe as an additional
    defendant. The district court held that the Project was not in
    violation of the CWA and granted summary judgment in
    favor of PGE and the Tribe.
    We agree with the district court that the Tribe was a
    required party, but we disagree on the question of the Tribe’s
    sovereign immunity. We hold that the CWA did not abrogate
    the Tribe’s immunity and that the suit should have been
    dismissed under Rule 19. We therefore do not reach the
    question whether PGE and the Tribe violated the CWA. We
    remand with instructions to vacate the judgment and dismiss
    the suit.
    8    DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC.
    I. Background
    A. The Clean Water Act
    The Clean Water Act was enacted in 1972 “to restore and
    maintain the chemical, physical, and biological integrity of
    the Nation’s waters.” 33 U.S.C. § 1251(a). The CWA makes
    it unlawful for any person to discharge any pollutant into
    navigable waters except as authorized by the Act. Id. § 1311.
    Under Section 401 of the CWA, an applicant for a federal
    license to engage in activity that may result in a discharge of
    a pollutant must obtain a water quality certification from the
    relevant State or interstate agency “that any such discharge
    will comply with the applicable provisions” of the Act. Id.
    § 1341(a)(1). A Section 401 certification, or “certificate,”
    attests that the activity will comply with the applicable laws,
    including State water quality standards and “any other
    appropriate requirement of State law set forth in such
    certification.” Id. § 1341(a)(1), (d). The certificate’s
    requirements become conditions of the federal license or
    permit. Id. § 1341(d).
    The CWA authorizes citizen suits “against any person
    (including (i) the United States, and (ii) any other
    governmental instrumentality or agency to the extent
    permitted by the eleventh amendment to the Constitution)
    who is alleged to be in violation of [] an effluent standard or
    limitation under this chapter.” Id. § 1365(a)(1). An “effluent
    standard or limitation” includes “a certification under section
    1341 of this title.” Id. § 1365(f). A “person” is defined as
    “an individual, corporation, partnership, association, State,
    municipality, commission, or political subdivision of a State,
    DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC.             9
    or any interstate body.” Id. § 1362(5). A “municipality” is
    defined, in turn, as
    a city, town, borough, county, parish, district,
    association, or other public body created by or
    pursuant to State law and having jurisdiction
    over disposal of sewage, industrial wastes, or
    other wastes, or an Indian tribe or an
    authorized Indian tribal organization, or a
    designated and approved management agency
    under section 1288 of this title.
    Id. § 1362(4).
    B. The Project
    The Pelton Round Butte Hydroelectric Project is a system
    consisting of three dams on the Deschutes River in Oregon.
    The Round Butte Dam, built in 1964, is the farthest upstream,
    forming Lake Billy Chinook behind it. Next is the Pelton
    Dam, forming Lake Simtustus. Farthest downstream is the
    Reregulating Dam, forming the Pelton Regulating Reservoir.
    Part of the Project is within the Warm Springs Indian
    Reservation. The Reservation is home to the Confederated
    Tribes of Warm Springs, which include the Wasco, Warm
    Springs, and Paiute tribes. The Tribe is the legal successor in
    interest to the Indian signatories of an 1855 treaty reserving
    the land for their exclusive use.
    In 1951, the Federal Power Commission, predecessor to
    the Federal Energy Regulatory Commission (“FERC”),
    issued a fifty-year license to PGE for the Project. In 1980,
    FERC amended the license to allow the Tribe to construct
    10 DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC.
    power generation facilities in the Reregulating Dam as a joint
    licensee.
    PGE and the Tribe subsequently filed competing
    applications for a new license. After entering into a Global
    Settlement and Compensation Agreement, PGE and the Tribe
    jointly applied to FERC for a new license in 2001. At the
    same time, they jointly applied for Section 401 certifications
    from the Tribe’s Water Control Board and Oregon’s
    Department of Environmental Quality (“DEQ”). The
    certifications were issued the following year. PGE and the
    Tribe also participated in a Settlement Working Group in
    order to address concerns of various stakeholders about the
    Project. Their efforts resulted in a Settlement Agreement,
    approved by FERC in 2005. A key part of the Settlement
    Agreement was a Fish Passage Plan designed to facilitate the
    movement of fish through the Project. FERC issued the new
    license, incorporating the DEQ water quality certification and
    most of the provisions of the Settlement Agreement.
    Pursuant to the DEQ certification and the Settlement
    Agreement, a Selective Water Withdrawal facility (“SWW”)
    at Round Butte Dam was completed in 2009. The SWW
    draws water from both the surface and bottom of Lake Billy
    Chinook to meet water quality standards downstream and to
    facilitate the passage of fish.
    C. DRA’s Citizen Suit
    DRA is a nonprofit advocacy organization established to
    protect the lower Deschutes River, formed shortly after the
    SWW began operation. Its members are concerned about the
    effect of the SWW’s operation on water quality in the river.
    DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC. 11
    On August 12, 2016, DRA brought suit against PGE
    under 33 U.S.C. § 1365, alleging that the Project was in
    violation of its Section 401 certificate. Defendant PGE
    moved to dismiss under Rule 19 for failure to join the Tribe
    as a required party. The Tribe, appearing as amicus, argued
    in support of the motion. The district court denied the
    motion, holding that the Tribe was a required party but
    feasible to be joined because the CWA had abrogated the
    Tribe’s sovereign immunity. DRA then filed an amended
    complaint joining the Tribe as an additional defendant.
    On August 3, 2018, the district court granted PGE and the
    Tribe’s motions for summary judgment, holding that the
    Project was not violating its Section 401 certificate. DRA
    appealed, and PGE and the Tribe cross-appealed. We have
    jurisdiction under 28 U.S.C. § 1291.
    II. Standards of Review
    “Both Article III standing and sovereign immunity are
    threshold jurisdictional issues that we review de novo.”
    Daniel v. Nat’l Park Serv., 
    891 F.3d 762
    , 765–66 (9th Cir.
    2018).
    We generally review a district court’s Rule 19
    determinations for abuse of discretion. Cachil Dehe Band of
    Wintun Indians of the Colusa Indian Cmty. v. California,
    
    547 F.3d 962
    , 969 (9th Cir. 2008). However, “[t]o the extent
    that the district court’s determination whether a party’s
    interest is impaired involves a question of law, we review de
    novo.” Pit River Home & Agric. Coop. Ass’n v. United
    States, 
    30 F.3d 1088
    , 1098 (9th Cir. 1994).
    12 DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC.
    III. Discussion
    PGE and the Tribe argue that DRA lacks Article III
    standing and that the CWA did not abrogate the Tribe’s
    sovereign immunity. We hold that DRA has Article III
    standing. We hold further that the CWA did not abrogate the
    Tribe’s sovereign immunity and that the district court should
    have dismissed DRA’s suit under Rule 19. We therefore do
    not reach the question whether the Project violates the CWA.
    A. Article III Standing
    The Supreme Court tells us that there are three core
    requirements for Article III standing. “The 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). PGE
    and the Tribe argue that DRA lacks Article III standing
    because it has failed to state a judicially redressable claim.
    They contend that DRA has not explained what available
    relief would improve water quality in the river, and that the
    district court is therefore without power to grant effective
    relief.
    DRA’s arguments are unavailing. To satisfy Article III,
    a plaintiff “need only show a substantial likelihood that the
    relief sought would redress the injury.” M.S. v. Brown,
    
    902 F.3d 1076
    , 1083 (9th Cir. 2018) (quotation marks and
    citation omitted). DRA seeks an injunction requiring PGE
    and the Tribe to comply with their Section 401 certificate,
    which it interprets as requiring compliance with particular
    water quality criteria. If the district court agreed with DRA’s
    argument on the merits, there is a substantial likelihood that
    DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC. 13
    an injunction requiring defendants meet these criteria would
    redress DRA’s alleged injury by improving the water quality
    of the lower Deschutes River. See Friends of the Earth, Inc.
    v. Laidlaw Env’t Servs., Inc., 
    528 U.S. 167
    , 185–86 (2000)
    (“It can scarcely be doubted that, for a plaintiff who is injured
    or faces the threat of future injury due to illegal conduct
    ongoing at the time of suit, a sanction that effectively abates
    that conduct and prevents its recurrence provides a form of
    redress.”); Weinberger v. Romero-Barcelo, 
    456 U.S. 305
    , 318
    (1982) (reading the CWA “as permitting the exercise of a
    court’s equitable discretion . . . to order relief that will
    achieve compliance with the Act”). DRA has thus carried its
    “relatively modest” burden of demonstrating redressability.
    See M.S., 902 F.3d at 1083.
    B. Tribal Sovereign Immunity
    “Suits against Indian tribes are . . . barred by sovereign
    immunity absent a clear waiver by the tribe or congressional
    abrogation.” Okla. Tax Comm’n v. Citizen Band Potawatomi
    Indian Tribe of Okla., 
    498 U.S. 505
    , 509 (1991). The Tribe
    and PGE argue that the district court erred in concluding
    Congress abrogated tribal immunity in the CWA. DRA
    argues that the Tribe waived its sovereign immunity through
    the Project’s Implementation Agreement, and that the district
    court was correct in holding that the CWA abrogated its
    immunity.
    We can quickly dispose of DRA’s waiver argument.
    DRA did not raise this argument in the district court. The
    argument is without merit in any event. “There is a strong
    presumption against waiver of tribal sovereign immunity.”
    Demontiney v. United States ex rel. Dep’t of Interior, Bureau
    of Indian Affs., 
    255 F.3d 801
    , 811 (9th Cir. 2001). DRA
    14 DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC.
    argues that the Tribe waived its immunity when it agreed not
    to assert sovereign immunity from a suit brought by a party
    to the Project’s Implementation Agreement. DRA is not a
    party to the Agreement, and the Tribe’s waiver does not apply
    to a suit brought by a non-party.
    DRA’s abrogation argument is more serious, though it
    ultimately fails. “[T]o abrogate immunity, Congress must
    unequivocally express that purpose. That rule of construction
    reflects an enduring principle of Indian law: Although
    Congress has plenary authority over tribes, courts will not
    lightly assume that Congress in fact intends to undermine
    Indian self-government.” Michigan v. Bay Mills Indian
    Cmty., 
    572 U.S. 782
    , 790 (2014) (quotation marks,
    alterations, and citations omitted). “[A] proper respect both
    for tribal sovereignty itself and for the plenary authority of
    Congress in this area cautions that we tread lightly in the
    absence of clear indications of legislative intent.” Santa
    Clara Pueblo v. Martinez, 
    436 U.S. 49
    , 60 (1978). We must
    be able to say with “perfect confidence that Congress meant
    to abrogate . . . sovereign immunity.” Daniel, 891 F.3d
    at 774 (quotation marks omitted); see Dellmuth v. Muth,
    
    491 U.S. 223
    , 231 (1989) (“[T]he salient point in our view is
    that it cannot be said with perfect confidence that Congress in
    fact intended . . . to abrogate sovereign immunity, and
    imperfect confidence will not suffice. . . .”).
    The text of the CWA does not provide the required
    “perfect confidence.” See 
    id.
     Section 1365—the citizen-suit
    provision—provides that “any citizen may commence a civil
    action on his own behalf . . . against any person (including
    (i) the United States, and (ii) any other governmental
    instrumentality or agency to the extent permitted by the
    eleventh amendment to the Constitution).” 33 U.S.C. 1365(a)
    DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC. 15
    (emphasis added). Section 1365 is the only section of the
    CWA dealing explicitly with sovereign immunity. Section
    1365 makes no mention of Indian tribes or tribal immunity.
    Clause (i) explicitly waives the United States’s sovereign
    immunity. Clause (ii) does not mention States specifically.
    Instead, it uses the umbrella term “any other [i.e., non-
    federal] governmental instrumentality or agency,” allowing
    suit against such entities only “to the extent permitted by the
    eleventh amendment.” States themselves are, of course,
    protected by the Eleventh Amendment (or, to be precise, by
    the sovereign immunity principle for which the Amendment
    stands). See Alden v. Maine, 
    527 U.S. 706
     (1999). State
    entities such as state hospitals are also protected by the
    Amendment. See Pennhurst State Sch. and Hosp. v.
    Halderman, 
    465 U.S. 89
     (1984). Non-state entities such as
    counties are not protected by the Amendment. See Lincoln
    Cnty. v. Luning, 
    133 U.S. 529
     (1890).
    Section 1362(5) defines a “person,” as “an individual,
    corporation, partnership, association, State, municipality,
    commission, or political subdivision of a State, or any
    interstate body.” 
    Id.
     § 1362(5) (emphasis added). Section
    1362(4), in turn, defines a “municipality” as a
    city, town, borough, county, parish, district,
    association, or other public body created by or
    pursuant to State law and having jurisdiction
    over disposal of sewage, industrial wastes, or
    other wastes, or an Indian tribe or an
    authorized Indian tribal organization, or a
    designated and approved management agency
    under section 1288 of this title.
    16 DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC.
    Id. § 1362(4) (emphasis added).
    DRA argues, and the district court agreed, that the
    reference to “an Indian tribe” in § 1362(4) is sufficient to
    abrogate tribal immunity because § 1365 provides that a
    citizen may commence an action “against any person”;
    “person” is defined in § 1362(5) to include “municipality”;
    and “municipality” is defined in § 1362(4) to include “an
    Indian tribe.” The presence of “an Indian tribe” in § 1362(4),
    however, can hardly be said to be a clear and unequivocal
    expression of Congressional intent to abrogate when
    Congress expressly dealt with sovereign immunity in 1365,
    but failed to mention tribes in that section.
    Indian tribes and States are both “persons” within the
    meaning of § 1365(a), given the definitional chains in
    § 1362(4) and (5). But it does not follow that unconsenting
    Indian tribes and States are subject to citizen suits under the
    CWA. We have already concluded as much for States. See
    Nat’l Res. Def. Council v. Cal. Dep’t of Transp., 
    96 F.3d 420
    ,
    423 (9th Cir. 1996); see also Burnette v. Carothers, 
    192 F.3d 52
    , 57 (2d Cir. 1999). There is little reason to conclude to the
    contrary for Indian tribes. Because Indian tribes and States
    both may waive their sovereign immunity and thus consent to
    suit under the CWA, the inclusion of Indian tribes and States
    in the definition of “person” is not meaningless. See, e.g.,
    C & L Enter., Inc. v. Citizens Band Potawatomi Tribe of
    Okla., 
    532 U.S. 411
    , 423 (2001) (tribal waiver); Coll. Sav.
    Bank v. Fla. Prepaid Postsecondary Educ. Expense Bd.,
    
    527 U.S. 666
    , 670 (1999) (state waiver).
    We therefore conclude that the inclusion of “an Indian
    tribe” in the definition of “municipality” (and, in turn, in the
    definition of “person”) does not indicate—let alone clearly
    DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC. 17
    indicate—that Congress intended in the CWA to subject
    tribes to unconsented suits.
    DRA points to the district court’s reliance on Blue Legs
    v. United States Bureau of Indian Affairs, 
    867 F.2d 1094
     (8th
    Cir. 1989), Osage Tribal Council ex rel. Osage Tribe of
    Indians v. United States Dep’t of Labor, 
    187 F.3d 1174
     (10th
    Cir. 1999), and Miller v. Wright, 
    705 F.3d 919
     (9th Cir.
    2013), in support of its argument that the CWA abrogates
    tribal immunity. None of these decisions changes our reading
    of the CWA.
    In Blue Legs, Oglala Sioux tribal members brought suit
    against the Environmental Protection Agency, other federal
    government agencies, and their own Tribe under the Resource
    Conservation and Recovery Act (“RCRA”), complaining of
    fourteen dangerous garbage dumps on the Reservation.
    
    867 F.2d 1094
    , 1095. The Eighth Circuit held that Congress
    clearly indicated in RCRA its intent to abrogate tribal
    immunity. 
    Id. at 1097
    . Under RCRA, as under the CWA,
    citizens may bring suit “against any person (including (a) the
    United States, and (b) any other governmental instrumentality
    or agency, to the extent permitted by the eleventh amendment
    to the Constitution).” 42 U.S.C. § 6972(a)(1)(A). As in the
    CWA, “person” is defined to include municipality, and
    municipality is defined in turn to include “an Indian tribe or
    authorized tribal organization.” Id. § 6903(15), (13)(A).
    Finally, as in the CWA, neither tribes nor tribal immunity are
    mentioned in the citizen-suit provision.
    The Eighth Circuit’s analysis was relatively brief. It
    followed the definitional chain from person to municipality
    to tribe, and relied on a House Report that included “specific
    examples of harm to be avoided, including Indian children
    18 DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC.
    playing in dumps on reservations.” Blue Legs, 
    867 F.2d at 1097
    . The court did not consider the significance of the
    absence of tribes from the citizen-suit provision where
    sovereign immunity was explicitly addressed. Further, the
    court cited our decision in State of Washington Dep’t of
    Ecology v. E.P.A., 
    752 F.2d 1465
     (9th Cir. 1985), in which
    we held that RCRA gives regulatory authority over tribes to
    the United States, but does not provide such authority to
    states. Blue Legs, 
    867 F.2d at 1097
    . In citing that case, the
    Eighth Circuit ignored the distinction between federal
    regulatory authority over a State or tribe, which does not
    implicate sovereign immunity from suit, and an unconsented
    suit under federal law against a State or tribe, which does.
    See, e.g., Alden, 
    527 U.S. at 754
    –55.
    We are not convinced that the Eighth Circuit in Blue Legs
    reached the correct conclusion in holding that RCRA
    abrogates tribal sovereign immunity. See, e.g., Subtitle D
    Regulated Facilities; State/Tribal Permit Program
    Determination of Adequacy; State/Tribal Implementation
    Rule (STIR), 61 Fed. Reg. 2584, 2588 (proposed Jan. 26,
    1996, by the Environmental Protection Agency) (“[By
    including Indian tribes in the definition of municipalities in
    RCRA], Congress apparently intended to make explicit that
    Indian Tribes could receive funds and assistance when
    available in the same manner as municipal governments. . . .
    There is no indication in the legislative history that Congress
    intended to abrogate any sovereign Tribal authority by
    defining them as ‘municipalities’ under RCRA.”). But even
    if the Eighth Circuit reached the correct result, we note a
    difference in the legislative histories of RCRA and the CWA.
    In support of its reading of RCRA, the Eighth Circuit cited
    Congress’s specifically expressed concern with the hazards
    created by garbage dumps on Indian reservations. The
    DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC. 19
    legislative history of the CWA contains no comparable
    expressed concern. The likely explanation for inclusion of
    Indian tribes in the definition of municipalities in the CWA
    is that Congress intended to make tribes eligible for federal
    grants, with no thought of subjecting tribes to unconsented
    suits. See, e.g., S. Rep. No. 92-414, reprinted in 1972
    U.S.C.C.A.N. 3668, 3742 (“The definition of municipalities
    is clarified to make clear that public bodies eligible for grants
    under this Act includes associations formed under State law
    for the purpose of dealing with water problems . . . as well as
    operating agencies established and approved under section
    209.”).
    In Osage Tribal Council, the Tenth Circuit held that the
    enforcement provision for whistleblowers in the Safe
    Drinking Water Act (“SDWA”) is “unambiguous,”
    establishing that Congress had “unequivocally waived tribal
    immunity.” 
    187 F.3d at 1182
    . (In a slip of the pen, the Tenth
    Circuit mistakenly wrote “waived” rather than “abrogated.”)
    Even assuming the Tenth Circuit’s holding was correct,
    which we need not decide, the case for abrogation in the
    SDWA is stronger than in the CWA. Under the SDWA
    enforcement provision, “[a]ny employee who believes that he
    has been discharged or otherwise discriminated against by
    any person” may file a complaint with the Secretary of Labor.
    42 U.S.C. § 300j–9(i)(2)(A). The SDWA then defines
    “person” to include “municipality” and “municipality” to
    include “an Indian tribe.” Id. § 300f(12), (10). Unlike the
    citizen-suit provision in the CWA, however, the enforcement
    provision of the SDWA does not mention the sovereign
    immunity of the United States or the Eleventh Amendment.
    Because the SDWA does not have a provision that deals
    specifically with sovereign immunity without mentioning
    20 DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC.
    tribal immunity, there is more reason to think the SDWA
    abrogates tribal sovereign immunity than does the CWA.
    In Miller, we held that the federal antitrust laws do not
    abrogate tribal sovereign immunity. In the course of our
    discussion, we noted and distinguished the decisions Blue
    Legs and Osage Tribal Council without explicitly endorsing
    their holdings. We wrote only that the antitrust laws do not
    “employ the sort of expansive language that we and other
    circuits have held to unequivocally abrogate tribal sovereign
    immunity.” Miller, 705 F.3d at 926. Our brief reference to
    Blue Legs and Osage Tribal Council was only “in passing
    without due consideration of the alternatives, [and] done as a
    prelude to another legal issue that command[ed] the panel’s
    full attention.” United States v. McAdory, 
    935 F.3d 838
    , 843
    (9th Cir. 2019) (alterations and quotation marks omitted).
    The distinction drawn in our discussion in Miller thus does
    not require us to conclude that Blue Legs and Osage Tribal
    Council were correctly decided.
    An intention to abrogate tribal sovereign immunity must
    be “unmistakably clear.” Dellmuth, 
    491 U.S. at 228
    ; Krystal
    Energy Co. v. Navajo Nation, 
    357 F.3d 1055
    , 1056 (9th Cir.
    2004) (noting “[i]dentical language is used by courts in
    determining whether Congress has abrogated the sovereign
    immunity of states” and tribes). We do not have “perfect
    confidence” that Congress intended to abrogate the sovereign
    immunity of Indian tribes from citizen suits under the CWA.
    See Daniel, 891 F.3d at 774. “In the absence here of any
    unequivocal expression of contrary legislative intent, . . . suits
    against the tribe under the [CWA] are barred by its sovereign
    immunity from suit.” Santa Clara Pueblo, 
    436 U.S. at 59
    .
    DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC. 21
    C. Dismissal for Failure to Join a Required Party
    Rule 19(a) requires joinder of a party whose presence is
    necessary to ensure complete relief among the existing
    parties, or to protect a party whose interests would be
    impaired or impeded were the action to proceed without that
    party. If joinder is not feasible, Rule 19(b) requires dismissal
    when the action cannot proceed “in equity and good
    conscience” without the required party. Under Rule 19,
    “[w]e first determine whether an absent party is a required
    party; then whether joinder is feasible; and finally whether
    the case can fairly proceed in the party’s absence.” Jamul
    Action Comm. v. Simermeyer, 
    974 F.3d 984
    , 996 (9th Cir.
    2020).
    The district court concluded that the Tribe is a required
    party because it has a legally protected interest in the subject
    of the suit that may be impaired by proceedings conducted in
    its absence. Fed. R. Civ. P. 19(a)(1)(B)(i). We agree with the
    district court. A decision that the Project is being operated in
    violation of its Section 401 certificate could well impair the
    Tribe’s interest as co-owner and co-operator of the Project,
    and any relief would risk adversely affecting the Tribe’s
    interests.
    Joinder of the Tribe is infeasible because of its sovereign
    immunity. We must therefore determine under Rule 19(b)
    whether the case can proceed in the Tribe’s absence. “The
    balancing of equitable factors under Rule 19(b) almost always
    favors dismissal when a tribe cannot be joined due to tribal
    sovereign immunity.” Jamul Action Comm., 974 F.3d at 998;
    see Kescoli v. Babbitt, 
    101 F.3d 1304
    , 1311 (9th Cir. 1996)
    (“If the necessary party is immune from suit, there may be
    very little need for balancing Rule 19(b) factors because
    22 DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC.
    immunity itself may be viewed as the compelling factor.”
    (quotation marks and citation omitted)). “[T]here is a ‘wall
    of circuit authority’ in favor of dismissing actions in which a
    necessary party cannot be joined due to tribal sovereign
    immunity—‘virtually all the cases to consider the question
    appear to dismiss under Rule 19, regardless of whether [an
    alternative] remedy is available, if the absent parties are
    Indian tribes invested with sovereign immunity.’” Dine
    Citizens Against Ruining Our Env’t v. Bureau of Indian Affs.,
    
    932 F.3d 843
    , 857 (9th Cir. 2019) (alteration in original)
    (quoting White v. Univ. of Cal., 
    765 F.3d 1010
    , 1028 (9th Cir.
    2014)).
    This case is no exception. DRA argues that PGE could
    adequately represent the Tribe were the suit to proceed in its
    absence. But PGE and the Tribe, as the district court noted,
    have potentially divergent interests. PGE’s interests in this
    litigation begin and end with the Project. By contrast, for the
    Tribe, the stakes of this litigation extend beyond the fate of
    the Project and implicate sovereign interests in self-
    governance and the preservation of treaty-based fishing rights
    throughout the Deschutes River Basin. Equity and good
    conscience thus do not permit DRA’s suit to proceed when
    the action involves protected interests of the Tribe that could
    be impaired in its absence. We therefore conclude that
    DRA’s suit must be dismissed under Rule 19 for failure to
    join a required party.
    Conclusion
    We hold that the CWA did not abrogate the Tribe’s
    sovereign immunity. The Tribe’s sovereign immunity
    requires dismissal of this suit, in which DRA challenges the
    operation of a large hydroelectric project co-owned and co-
    DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC. 23
    operated by the Tribe, and located partly on the Tribe’s
    reservation. We reverse the district court’s grant of summary
    judgment. We remand with instructions to vacate the entry
    of judgment and to dismiss the suit for failure to join the
    Tribe.
    REVERSED and REMANDED with instructions.
    BEA, Circuit Judge, dissenting in part, concurring in
    judgment:
    I join the majority in most of its holdings, but I believe
    the majority is wrong in one regard. On the issue of tribal
    immunity, the majority is correct that the text of the Clean
    Water Act (“CWA”) does not evince Congress’s clear intent
    to abrogate tribal immunity. That reasoning is dispositive,
    and is the basis for my concurrence in the judgment on that
    point. However, the majority then cites the legislative history
    of the CWA as additional support for its determination.
    I do not consider legislative history a useful nor proper
    means to interpret legislation, or to distinguish the CWA
    from other statutes. It is neither “legislative,” because it is
    prepared by unelected bureaucrats, and neither enacted nor
    presented to the executive, nor “history,” but congealed
    propaganda, picked by interested advocates, not by balanced
    historians. It is likely not to have even been read by any
    legislators. Hirschey v. FERC, 
    777 F.2d 1
    , 7–8 n.1 (D.C. Cir.
    1985) (Justice Scalia quoting an exchange between Senators
    Dole and Armstrong during a floor debate on a tax bill). I
    would apply the negative-implication canon expressio unius
    est exclusio alterius. “[This doctrine] as applied to statutory
    24 DESCHUTES RIVER ALL. V. PORTLAND GEN. ELEC.
    interpretation creates a presumption that when a statute
    designates certain persons, things, or manners of operation,
    all omissions should be understood as exclusions.” Wheeler
    v. City of Santa Clara, 
    894 F.3d 1046
    , 1054 (9th Cir. 2018)
    (internal quotations omitted). The citizen-suit provision of
    the CWA, 33 U.S.C. § 1365, deals with the sovereign
    immunity of the federal government and of the states of the
    union. It makes no mention of the Indian Tribes. Thus, that
    provision does not affect the Tribes’ sovereign immunity.
    The Opinion’s references to legislative history are
    superfluous and irrelevant.
