    UNITED STATES V. WASHINGTON                            3
    SUMMARY**
    Tribal Fishing Rights
    The panel affirmed the district court’s order issuing an
    injunction directing the State of Washington to correct
    culverts, which allow streams to flow underneath roads,
    because they violated, and continued to violate, the Stevens
    Treaties, which were entered in 1854–55 between Indian
    tribes in the Pacific Northwest and the Governor of
    Washington Territory.
    As part of the Treaties, the Tribes relinquished large
    swaths of land, watersheds, and offshore waters adjacent to
    those areas (collectively, the “Case Area”), in what is now
    the State of Washington. In exchange, the Tribes were
    guaranteed a right to engage in off-reservation fishing.
    In 1970, the United States brought suit against the State
    of Washington on behalf of the Tribes to resolve a persistent
    conflict over fishing rights; and in a 1974 decision, the
    district court authorized the parties to invoke its continuing
    jurisdiction to resolve continuing disputes.
    The panel held that in building and maintaining barrier
    culverts within the Case Area, Washington violated, and was
    continuing to violate, its obligation to the Tribes under the
    Treaties. The panel also held that because treaty rights
    belong to the Tribes rather than the United States, it was not
    the prerogative of the United States to waive them.

    4             UNITED STATES V. WASHINGTON
    Concerning the State of Washington’s cross-request
    seeking an injunction that would require the United States to
    fix its culverts before Washington repaired its culverts, the
    panel held that Washington’s cross-request was barred by
    sovereign immunity, and Washington did not have standing
    to assert any treaty rights belonging to the Tribes.
    Specifically, the panel held that Washington’s cross-request
    for an injunction did not qualify as a claim for recoupment.
    The panel also held that the United States did not waive its
    own sovereign immunity by bringing suit on behalf of the
    Tribes. The panel further held that any violation of the
    Treaties by the United States violated rights held by the
    Tribes rather than the State, and the Tribes did not seek
    redress against the United States in this proceeding.
    The panel held that the district court did not abuse its
    discretion in enjoining Washington to correct most of its
    high-priority barrier culverts within seventeen years, and to
    correct the remainder at the end of their natural life or in the
    course of road construction project undertaken for
    independent reasons. The panel rejected Washington’s
    objections that the injunction was too broad, that the district
    court did not defer to the State’s expertise, that the court did
    not properly consider costs and equitable principles, that the
    injunction impermissibly intruded into state government
    operations, and that the injunction was inconsistent with
    federalism principles.

    6            UNITED STATES V. WASHINGTON
    OPINION
    W. FLETCHER, Circuit Judge:
    In 1854 and 1855, Indian tribes in the Pacific Northwest
    entered into a series of treaties, now known as the “Stevens
    Treaties,” negotiated by Isaac I. Stevens, Superintendent of
    Indian Affairs and Governor of Washington Territory. Under
    the Stevens Treaties (“Treaties”) at issue in this case, the
    tribes relinquished large swaths of land west of the Cascade
    Mountains and north of the Columbia River drainage area,
    including the Puget Sound watershed, the watersheds of the
    Olympic Peninsula north of the Grays Harbor watershed, and
    the offshore waters adjacent to those areas (collectively, the
    “Case Area”), in what is now the State of Washington. In
    exchange for their land, the tribes were guaranteed a right to
    off-reservation fishing, in a clause that used essentially
    identical language in each treaty. The “fishing clause”
    guaranteed “the right of taking fish, at all usual and
    accustomed grounds and stations . . . in common with all
    citizens of the Territory.”
    In 2001, pursuant to an injunction previously entered in
    this long-running litigation, twenty-one Indian tribes
    (“Tribes”), joined by the United States, filed a “Request for
    Determination” — in effect, a complaint — in the federal
    district court for the Western District of Washington. The
    Tribes include the Suquamish Indian Tribe, Jamestown
    S’Klallam, Lower Elwha Band of Klallams, Port Gamble
    Clallam, Nisqually Indian Tribe, Nooksack Tribe, Sauk-
    Suiattle Tribe, Skokomish Indian Tribe, Squaxin Island Tribe,
    Stillaguamish Tribe, Upper Skagit Tribe, Tulalip Tribes,
    Lummi Indian Nation, Quinault Indian Nation, Puyallup
    Tribe, Hoh Tribe, Confederated Tribes and Bands of the
    UNITED STATES V. WASHINGTON                     7
    Yakama Indian Nation, Quileute Indian Tribe, Makah Indian
    Tribe, Swinomish Indian Tribal Community, and the
    Muckleshoot Indian Tribe. The Tribes contended that
    Washington State (“Washington” or “the State”) had violated,
    and was continuing to violate, the Treaties by building and
    maintaining culverts that prevented mature salmon from
    returning from the sea to their spawning grounds; prevented
    smolt (juvenile salmon) from moving downstream and out to
    sea; and prevented very young salmon from moving freely to
    seek food and escape predators. In 2007, the district court
    held that in building and maintaining these culverts
    Washington had caused the size of salmon runs in the Case
    Area to diminish and that Washington thereby violated its
    obligation under the Treaties. In 2013, the court issued an
    injunction ordering Washington to correct its offending
    culverts.
    We affirm the decision of the district court.
    I. Historical Background
    For over a hundred years, there has been conflict between
    Washington and the Tribes over fishing rights under the
    Treaties. We recount here some of the most salient aspects of
    this history.
    When white settlers arrived in the Washington territory in
    the second half of the nineteenth century, many settled on
    riparian land and salt-water shoreline. Even though the
    majority of these settlers were not themselves fishermen, they
    blocked access to many of the Tribes’ traditional fishing sites.
    By the end of the century, white commercial fishermen were
    catching enormous quantities of salmon, first on the
    8             UNITED STATES V. WASHINGTON
    Columbia River and then in Puget Sound as well, supplying
    large-scale canneries.
    In 1894, L. T. Erwin, the United States Indian Agent for
    the Yakimas, complained that whites had blocked access to
    the Indians’ “accustomed fisheries” on the Columbia River:
    “[I]nch by inch, [the Indians] have been forced back until all
    the best grounds have been taken up by white men, who now
    refuse to allow them to fish in common, as the treaty
    provides.” Report of the Secretary of the Interior, 1894
    (3 vols., Washington, D.C., 1894, II, 326). In 1897, D. C.
    Govan, the Indian Agent for the Tulalips on Puget Sound
    reported that “the Alaska Packing Company and other
    cannery companies have practically appropriated all the best
    fishing grounds at Point Roberts and Village Point, where the
    Lummi Indians have been in the habit of fishing from time
    immemorial.” Annual Reports of the Department of the
    Interior, 1897: Report of the Commissioner of Indian Affairs
    (Washington, D.C., 1897, 297). In 1905, Charles Buchanan,
    the new Indian Agent for the Tulalips, complained, “The
    tremendous development of the fisheries by traps and by trust
    methods of consolidation, concentration, and large local
    development are seriously depleting the natural larders of our
    Indians and cutting down their main reliance for support and
    subsistence. Living for them is becoming more precarious
    year by year.” Annual Reports of the Department of the
    Interior, 1905: Indian Affairs (Washington, D.C., 1906, Part
    I, 362). During this period, “[t]he superior capital, large-scale
    methods, and aggressiveness of whites . . . quickly led to their
    domination of the prime fisheries of the region.” Donald L.
    Parman, Inconstant Advocacy: The Erosion of Indian Fishing
    Rights in the Pacific Northwest, 53 Pacific Hist. Rev. 163,
    167 (1984).
    UNITED STATES V. WASHINGTON                    9
    The United States Supreme Court first addressed the
    conflict over fisheries in United States v. Winans, 
    198 U.S. 371
    (1905). The Winans brothers had acquired land at a
    prime Yakima fishing site on the Washington side of the
    Columbia River. See Michael C. Blumm and James
    Brunberg, ‘Not Much Less Necessary . . . Than the
    Atmosphere They Breathed’: Salmon, Indian Treaties, and
    the Supreme Court — a Centennial Remembrance of United
    States v. Winans and Its Enduring Significance, 46 Nat.
    Resources J. 489, 523 (2006). Under an exclusive license
    from the State, the Winanses operated “fish wheels” at the
    site. Fish wheels were essentially mechanized dip nets
    “capable of catching salmon by the ton.” Washington v.
    Wash. State Commercial Passenger Fishing Vessel Ass’n,
    
    443 U.S. 658
    , 679 (1979). The Winanses refused to allow the
    Yakimas to cross over or to camp on their land in order to
    fish at the site.
    The Yakimas had signed one of the Stevens Treaties in
    1855. The United States brought suit against the Winanses
    on the Yakimas’ behalf. The Supreme Court held that the
    land owned by the Winanses, previously conveyed by patent
    from the government, was by virtue of the treaty subject to an
    easement allowing access to the Yakimas’ “usual and
    accustomed” fishing site. The Court held, further, that the
    State could not license the Winanses to “construct and use a
    device which gives them exclusive possession of the fishing
    places, as it is admitted a fish wheel does.” 
    Winans, 198 U.S. at 382
    . See also Seufort Bros. Co. v. United States, 
    249 U.S. 194
    (1919) (holding that the Yakimas had rights under the
    treaty on the Oregon, as well as the Washington, side of the
    river).
    10            UNITED STATES V. WASHINGTON
    diminished supply of salmon and the harsh application of
    Washington’s fish and game laws against the Indians. He
    wrote:
    [M]ore recently, the use of large capital,
    mechanical assistance, numerous great traps,
    canneries, etc., and other activities allied to
    the fishery industry, have greatly lessened and
    depleted the Indians’ natural sources of food
    supply. In addition thereto the stringent and
    harsh application to Indians of the State game
    and fish laws have made it still and
    increasingly precarious for him to procure his
    natural foods in his natural way.
    Rights of the Puget Sound Indians to Game and Fish, 6 Wash.
    Hist. Quart. 109, 110 (Apr. 1915).
    The next year, the Washington Supreme Court upheld the
    sort of “stringent and harsh application . . . of game and fish
    laws” of which Buchanan complained. In State v.
    Towessnute, 
    154 P. 805
    , 806 (Wash. 1916), a member of the
    Yakima Nation named Towessnute was charged with off-
    reservation fishing without a license in a manner forbidden by
    state law. Towessnute defended on the ground that he was
    fishing in the traditional manner at one the Yakimas’ usual
    and accustomed places, and that he was entitled to do so
    under the treaty at issue in Winans. 
    Id. Characterizing the
    treaty as a “dubious document,” 
    id., the Washington
    Supreme
    Court rejected the defense:
    The premise of Indian sovereignty we reject.
    The treaty is not to be interpreted in that light.
    At no time did our ancestors in getting title to
    UNITED STATES V. WASHINGTON                      11
    this continent, ever regard the aborigines as
    other than mere occupants . . . of the soil.
    
    Id. at 807.
    The Court read the Supreme Court’s holding in
    Winans as requiring easements across private land, but at the
    same time as endorsing the authority of the state, through the
    exercise of its “police power,” to enact regulatory laws
    restricting Indian fishing rights. 
    Id. at 809.
    See also State v.
    Alexis, 
    154 P. 810
    (Wash. 1916) (holding the same under the
    Stevens Treaty with the Lummi Tribe in Puget Sound).
    Much traditional Indian fishing was done with traps and
    nets in rivers, catching mature salmon when they returned to
    their native habitat to spawn. White commercial fishermen,
    by contrast, often fished in salt water, using equipment that
    most Indians could not afford and catching both mature and
    immature salmon. Beginning in the early 1900s, the State
    regulated the salmon fishery in Puget Sound in such a way
    that Indians who fished in rivers were increasingly unable to
    exercise their off-reservation treaty right to fish in their usual
    and accustomed places and in their traditional manner. For
    example, in 1907 the Washington legislature forbade all off-
    reservation fishing above the tide line — by whites and
    Indians alike — except by hook and line. Wash. Sess. Laws
    Ch. 247, Sec. 2 (1907).
    In 1934, Washington voters adopted Initiative 77, a
    measure that limited off-reservation commercial fishing to
    certain portions of Puget Sound and banned the use of fixed
    gear, such as the “pound net, fish trap, fish wheel, scow fish
    wheel, set net, or any fixed appliance,” to catch salmonids.
    Init. Measure No. 77, State of Wash. Voting Pamphlet 5
    (Nov. 6, 1934). According to a report commissioned by the
    federal Bureau of Indian Affairs, the passage of Initiative 77
    12            UNITED STATES V. WASHINGTON
    “constituted a serious blow to the Indian fishing being carried
    on at usual and accustomed grounds”:
    [D]ue to their extremely limited financial
    means, [the Indians’] gear necessarily must be
    obtainable at a minimum of expense.
    Generally speaking, the Indians are unable to
    finance the purchase of other more expensive
    gear and operating equipment, the use of
    which was not entirely outlawed. In order to
    continue to provide the necessities of life, the
    Indians, as a result of the above conservation
    statute, were literally forced to confine their
    fishing with such gear to reservation waters.
    The fact that such was the situation led to
    considerable agitation in the Pacific
    Northwest and especially in the [S]tate of
    Washington looking to the further curtailment
    of the Indians’ commercial fishery.
    Edward Swindell, Report on Source, Nature and Extent
    of Fishing, Hunting, and Miscellaneous Rights of Certain
    Indian Tribes in Washington and Oregon 95 (1942).
    In subsequent years, the State continued to assert
    authority to regulate off-reservation fishing by Indians,
    including authority to require purchase of fishing licences. In
    1939, Sampson Tulee, a Yakima Indian, was criminally
    charged with off-reservation commercial fishing with a dip
    net on the Columbia River without a state license. Citing
    Towessnute and Alexis, the Washington Supreme Court
    affirmed the conviction as a valid exercise of the State’s
    police powers. Washington v. Tulee, 
    109 P.2d 280
    , 287
    (Wash. 1941) (“Washington enjoys to the full the exercise of
    UNITED STATES V. WASHINGTON                     13
    its police powers.”). The United States Supreme Court
    reversed. The Court held that while the State had the power,
    consistent with the treaty, to regulate fishing by both Indians
    and non-Indians to the degree “necessary for the conservation
    of fish,” the exaction of a license fee “cannot be reconciled
    with a fair construction of the treaty.” Tulee v. Washington,
    
    315 U.S. 681
    , 684–85 (1942).
    After Tulee, state officials continued to enforce
    restrictions on off-reservation fishing by Puget Sound
    Indians, even when that fishing was conducted at the Indians’
    usual and accustomed places:
    Over the years the state fish and game
    authorities have asserted that Indian treaty-
    protected fishing exists only on the
    reservations, and have acted to enforce this
    position. Injunctions against off-reservation
    fishing by Indians of the Nisqually, Puyallup,
    and Muckleshoot tribes have been obtained
    and enforcement actions carried out even
    while the injunctions are being contested in
    the courts.     Arrests of fishermen and
    confiscation of gear have seriously hampered
    the Indians. Valuable gear held by the state as
    evidence can effectively put the fisherman out
    of business during several runs of fish, even
    though he may eventually win his case.
    Walter Taylor, Uncommon Controversy: Fishing Rights of the
    Muckleshoot, Puyallup, and Nisqually Indians 60 (1970). As
    a result of the State’s hostility to off-reservation fishing, the
    Indians’ share of the overall catch was relatively small. For
    example, from 1958 through 1967, the shares of the total
    14            UNITED STATES V. WASHINGTON
    salmon catch in Puget Sound were 6% for Indian fishing,
    8.5% for sports fishing, and 85.5% for commercial fishing.
    
    Id. at 123,
    126.
    Beginning in the early 1960s, the State substantially
    increased its enforcement against off-reservation fishing in
    Puget Sound. See generally Bradley G. Shreve, “From Time
    Immemorial”: The Fish-in Movement and the Rise of
    Intertribal Activism, 78 Pacific Hist. Rev. 403, 411–15
    (2009). In response, in 1964 the National Indian Youth
    Council organized a large demonstration in Olympia to
    demand that the State acknowledge their treaty fishing rights.
    See Uncommon 
    Controversy, supra, at 107
    –13. During the
    1960s and early 1970s, in what came to be called the “fish
    wars,” some Indians fished openly and without licenses in
    “fish-ins” to bring attention to the State’s prohibitions against
    off-reservation fishing. State reaction to the “fish-ins”
    sometimes led to violence. See, e.g., Associated Press,
    “Shots Fired, 60 Arrested in Indian-Fishing Showdown,”
    Seattle Times, Sept. 9, 1970; Alex Tizon, “The Boldt
    Decision / 25 Years — The Fish Tale That Changed History,”
    Seattle Times, Feb. 7, 1999 (describing the State’s “military-
    style campaign,” employing “surveillance planes, high-
    powered boats and radio communications,” as well as “tear
    gas,” “billy clubs,” and “guns”).
    In 1970, in an effort to resolve the persistent conflict
    between the State and the Indians, the United States brought
    suit against the State on behalf of the Tribes. The dispute
    now before us is part of that litigation.

    II. Anadromous Fisheries and Washington’s Barrier
    Culverts
    Anadromous fish, such as salmon, hatch and spend their
    early lives in fresh water, migrate to the ocean to mature, and
    return to their waters of origin to spawn. Washington is home
    to several anadromous fisheries, of which the salmon fishery
    is by far the most important. Before the arrival of white
    settlers, returning salmon were abundant in the streams and
    rivers of the Pacific Northwest. Present-day Indian tribes in
    the Pacific Northwest eat salmon as an important part of their
    diet, use salmon in religious and cultural ceremonies, and fish
    for salmon commercially.
    Roads often cross streams that salmon and other
    anadromous fish use for spawning. Road builders construct
    culverts to allow the streams to flow underneath roads, but
    many culverts do not allow fish to pass easily. Sometimes
    they do not allow fish passage at all. A “barrier culvert” is a
    culvert that inhibits or prevents fish passage. Road builders
    can avoid constructing barrier culverts by building roads
    away from streams, by building bridges that entirely span
    streams, or by building culverts that allow unobstructed fish
    passage.
    Four state agencies are responsible for building and
    managing Washington’s roads and the culverts that pass
    under them: Washington State Department of Transportation
    (“WSDOT”), Washington State Department of Natural
    Resources (“WSDNR”), Washington State Parks and
    Recreation Commission (“State Parks”), and Washington
    Department of Fisheries and Wildlife (“WDFW”). Of these,
    WSDOT, the agency responsible for Washington’s highways,
    builds and maintains by far the most roads and culverts.
    16            UNITED STATES V. WASHINGTON
    III. Earlier Proceedings
    In 1970, the United States, on its own behalf and as
    trustee for Pacific Northwest tribes, sued Washington in
    federal court in the Western District of Washington. The
    United States sought declaratory and injunctive relief based
    on the fishing clause of the Treaties. United States v. State of
    Washington, 
    384 F. Supp. 312
    , 327–28 (W.D. Wash. 1974)
    (“Washington I”). In what has come to be known as the
    “Boldt decision,” District Judge George H. Boldt divided the
    case into two phases. Phase I was to determine what portion,
    if any, of annually harvestable fish were guaranteed to the
    Tribes by the fishing clause. Phase II was to determine
    whether the fishing clause extends to hatchery fish, and
    whether it requires Washington to prevent environmental
    degradation within the Case Area.
    In Phase I, Judge Boldt held that the phrase “the right of
    taking fish . . . in common with all citizens” gives the Tribes
    the right to take up to fifty percent of the harvestable fish in
    the Case Area, subject to the right of non-treaty fishers to do
    the same. 
    Id. at 343.
    The Supreme Court affirmed in
    Washington v. Washington State Commercial Passenger
    Fishing Vessel Ass’n, 
    443 U.S. 658
    (1979) (“Fishing
    Vessel”). The Court specified that fifty percent was a ceiling
    rather than a floor, and that the fishing clause guaranteed “so
    much as, but no more than, is necessary to provide the
    Indians with a livelihood—that is to say, a moderate living.”
    
    Id. at 686.
    In accordance with its standard practice of
    interpreting Indian treaties in favor of the tribes, the Court
    interpreted the clause as promising protection for the tribes’
    supply of fish, not merely their share of the fish. The Court
    wrote:
    UNITED STATES V. WASHINGTON                    17
    Governor Stevens and his associates were
    well aware of the “sense” in which the Indians
    were likely to view assurances regarding their
    fishing rights. During the negotiations, the
    vital importance of the fish to the Indians was
    repeatedly emphasized by both sides, and the
    Governor’s promises that the treaties would
    protect that source of food and commerce
    were crucial in obtaining the Indians’ assent.
    
    Id. at 676.
    In 1976, the United States initiated Phase II of the
    litigation, asking for a declaratory judgment clarifying the
    Tribes’ rights with respect to the “hatchery fish” issue and to
    the “environmental” issue. United States v. State of
    Washington, 
    506 F. Supp. 187
    , 194 (W.D. Wash. 1980)
    (“Washington II”). The district court held, first, that hatchery
    fish must be included in determining the share of fish to
    which the Tribes are entitled. 
    Id. at 197.
    It held, second, that
    the Tribes’ right to “a sufficient quantity of fish to satisfy
    their moderate living needs” entailed a “right to have the
    fishery habitat protected from man-made despoliation.” 
    Id. at 208,
    203.
    Sitting en banc, we affirmed in part and vacated in part.
    United States v. State of Washington, 
    759 F.2d 1353
    (9th Cir.
    1985) (en banc) (“Washington III”). We affirmed the district
    court’s decision that hatchery fish must be included in
    determining the share of salmon to be allocated to the Tribes:
    The hatchery programs have served a
    mitigating function since their inception in
    1895. They are designed essentially to
    18            UNITED STATES V. WASHINGTON
    replace natural fish lost to non-Indian
    d egrad at i on o f t h e h a b i t a t a n d
    commercialization of the fishing industry.
    Under these circumstances, it is only just to
    consider such replacement fish as subject to
    treaty allocation. For the tribes to bear the
    full burden of the decline caused by their non-
    Indian neighbors without sharing the
    replacement achieved through the hatcheries,
    would be an inequity and inconsistent with the
    Treaty.
    
    Id. at 1360
    (citations omitted).
    We vacated the court’s decision on the environmental
    issue. We held that the issue was too broad and varied to be
    resolved in a general and undifferentiated fashion, and that
    the issue of human-caused environmental degradation must
    be resolved in the context of particularized disputes. We
    wrote:
    We choose to rest our decision in this case on
    the proposition that issuance of the
    declaratory judgment on the environmental
    issue is contrary to the exercise of sound
    judicial discretion. The legal standards that
    will govern the State’s precise obligations and
    duties under the treaty with respect to the
    myriad State actions that may affect the
    environment of the treaty area will depend for
    their definition and articulation upon concrete
    facts which underlie a dispute in a particular
    case.
    UNITED STATES V. WASHINGTON                    19
    
    Id. at 1357.
    Although we vacated the district court’s decision
    with respect to the environmental issue, we made clear that
    we were not absolving Washington of environmental
    obligations under the fishing clause. We concluded the
    section of our opinion devoted to the environmental issue by
    emphasizing that Washington “is bound by the treaty.” 
    Id. Judge Boldt’s
    1974 decision authorized the parties to
    invoke the continuing jurisdiction of the district court to
    resolve disputes “concerning the subject matter of this case.”
    Washington 
    I, 384 F. Supp. at 419
    ; see also United States v.
    Washington, 
    573 F.3d 701
    , 705 (9th Cir. 2009). For such
    disputes, the court directed the parties to “file with the clerk
    of this court . . . a ‘Request for Determination’ setting forth
    the factual nature of the request and any legal authorities and
    argument which may assist the court, along with a statement
    that unsuccessful efforts have been made by the parties to
    resolve the matter, whether a hearing is required, and any
    factors which bear on the urgency of the request.”
    Washington 
    I, 384 F. Supp. at 419
    .
    In 2001, the Tribes filed a Request for Determination
    (“Request”), seeking “to enforce a duty upon the State of
    Washington to refrain from constructing and maintaining
    culverts under State roads that degrade fish habitat so that
    adult fish production is reduced.” The Tribes sought a
    permanent injunction from the district court “requiring
    Washington to identify and then to open culverts under state
    roads and highways that obstruct fish passage, for fish runs
    returning to or passing through the usual and accustomed
    grounds and stations of the plaintiff tribes.”
    The United States joined the Tribes’ Request, seeking a
    declaration from the court that:
    20            UNITED STATES V. WASHINGTON
    The right of taking fish secured to the
    plaintiff tribes in the Stevens Treaties imposes
    a duty upon the State of Washington to refrain
    from degrading the fishery resource through
    the construction or maintenance of culverts
    under State owned roads and highways in a
    way that deprives the Tribes of a moderate
    living from the fishery.
    The State has violated and continues to
    violate the duty owed to the plaintiff tribes
    under the Stevens Treaties through the
    operation and maintenance of culverts which
    reduce the number of fish that would
    otherwise return to or pass through the Tribes’
    usual and accustomed fishing grounds and
    stations to such a degree as would deprive the
    Tribes of the ability to earn a moderate living
    from the fishery.
    The United States sought a permanent injunction that would
    require Washington “within five years of the date of
    judgment (or such other time period as the Court deems
    necessary and just)” to “repair, retrofit, maintain, or replace”
    culverts that “degrade appreciably” the passage of fish.
    Washington and the defendant state agencies (collectively
    “Washington” or “the State”) answered by declaring that
    there is “no treaty-based right or duty of fish habitat
    protection as described” in the Request. In the alternative,
    Washington emphasized that some of its barrier culverts pass
    under highways funded in part by the United States, and that
    these highways were “designed according to standards set or
    approved” by the Federal Highway Administration, leading
    UNITED STATES V. WASHINGTON                    21
    Washington to believe that its culverts complied with the
    Treaties. Further, Washington asserted that the United States
    and the Tribes have built and maintained barrier culverts on
    their own lands within the Case Area. Washington asserted
    that the United States “has a duty to take action on its own
    lands so as not to place on the State of Washington an unfair
    burden of complying with any such treaty-based duty.”
    Washington also made a “cross-request” — in effect, a
    counterclaim — against the United States seeking a
    declaration that the United States has violated its own duty to
    the Tribes under the Treaties, and seeking an injunction that
    would require the United States to modify or replace its own
    barrier culverts. The district court dismissed the cross-
    request on the ground that the United States had not waived
    its sovereign immunity. The court later denied Washington’s
    request to file an amended cross-request on the additional
    ground that Washington did not have standing. It wrote,
    “[T]he State may not assert a treaty-based claim on behalf of
    the Tribes. . . . The decision as whether and when to assert
    that claim against the United States is for the Tribes alone.”
    The district court granted summary judgment in favor of
    the Tribes and the United States, concluding that the dispute
    involved the kind of “concrete facts” that were lacking in
    Washington III. The court held, first, that “the right of taking
    fish, secured to the Tribes in the Stevens Treaties, imposes a
    duty upon [Washington] to refrain from building or operating
    culverts under State-maintained roads that hinder fish passage
    and thereby diminish the number of fish that would otherwise
    be available for Tribal harvest.” It held, second, that “the
    State of Washington currently owns and operates culverts that
    violate this duty.”
    22            UNITED STATES V. WASHINGTON
    The district court conducted a bench trial in 2009 and
    2010 to determine the appropriate remedy. After failed
    efforts to reach a settlement, the court issued both a
    Memorandum and Decision and a Permanent Injunction. In
    its Memorandum and Decision, issued in 2013, the court
    found that Governor Stevens had assured the Tribes that they
    would have an adequate supply of salmon forever. The court
    wrote:
    During the negotiations leading up to the
    signing of the treaties, Governor Isaac Stevens
    and other negotiators assured the Tribes of
    their continued access to their usual fisheries.
    Governor Stevens assured the Tribes that even
    after they ceded huge quantities of land, they
    would still be able to feed themselves and
    their families forever. As Governor Stevens
    stated, “I want that you shall not have simply
    food and drink now but that you may have
    them forever.”
    (Emphasis added.)
    The court found that salmon stocks in the Case Area have
    declined “alarmingly” since the Treaties were signed, and
    “dramatically” since 1985. The court wrote, “A primary
    cause of this decline is habitat degradation, both in breeding
    habitat (freshwater) and feeding habitat (freshwater and
    marine areas) . . . . One cause of the degradation of salmon
    habitat is . . . culverts which do not allow the free passage of
    both adult and juvenile salmon upstream and downstream.”
    The “consequent reduction in tribal harvests has damaged
    tribal economies, has left individual tribal members unable to
    UNITED STATES V. WASHINGTON                    23
    earn a living by fishing, and has caused cultural and social
    harm to the Tribes in addition to the economic harm.”
    The district court entered a Permanent Injunction on the
    same day it issued its Memorandum and Decision. The court
    ordered the State, in consultation with the Tribes and the
    United States, to prepare within six months a current list of
    all state-owned barrier culverts within the Case Area. It
    ordered WSDNR, State Parks, and WDFW to correct all their
    barrier culverts on the list by the end of October 2016. It
    ordered WSDOT to correct many of its barrier culverts within
    seventeen years, and to correct the remainder only at the end
    of the culverts’ natural life or in connection with
    independently undertaken highway projects. We provide a
    more detailed description of the injunction below.
    IV. Standard of Review
    We review de novo dismissals for want of jurisdiction
    under Rule 12(b)(1) and for failure to state a claim under
    Rule 12(b)(6). Rhoades v. Avon Products, Inc., 
    504 F.3d 1151
    , 1156 (9th Cir. 2007). We also review de novo a grant
    or denial of summary judgment. Scott v. Pasadena Unified
    Sch. Dist., 
    306 F.3d 646
    , 652 (9th Cir. 2002). We review
    permanent injunctions under three standards: we review
    factual findings for clear error, legal conclusions de novo, and
    the scope of the injunction for abuse of discretion. 
    Id. at 653.
    V. Discussion
    Washington objects to the decision of the district court on
    a number of grounds. It objects to the court’s interpretation
    of the Stevens Treaties, contending that it has no treaty-based
    duty to refrain from building and maintaining barrier culverts;
    24            UNITED STATES V. WASHINGTON
    to the overruling of its waiver defense; to the dismissal of its
    cross-request against the United States; and to the injunction.
    We take the State’s objections in turn.
    A. Washington’s Duty under the Treaties
    The fishing clause of the Stevens Treaties guarantees to
    the Tribes a right to engage in off-reservation fishing. It
    provides, in its entirety:
    The right of taking fish, at all usual and
    accustomed grounds and stations, is further
    secured to said Indians, in common with all
    citizens of the Territory, and of erecting
    temporary houses for the purpose of curing,
    together with the privilege of hunting,
    gathering roots and berries, and pasturing
    their horses on open and unclaimed lands:
    Provided, however, That they shall not take
    shell fish from any beds staked or cultivated
    by citizens.
    Fishing 
    Vessel, 443 U.S. at 674
    (emphasis in original).
    Washington concedes that the clause guarantees to the Tribes
    the right to take up to fifty percent of the fish available for
    harvest, but it contends that the clause imposes no obligation
    on the State to ensure that any fish will, in fact, be available.
    In its brief to us, Washington denies any treaty-based duty
    to avoid blocking salmon-bearing streams:
    [T]he Tribes here argue for a treaty right that
    finds no basis in the plain language or
    historical interpretation of the treaties. On its
    UNITED STATES V. WASHINGTON                     25
    face, the right of taking fish in common with
    all citizens does not include a right to prevent
    the State from making land use decisions that
    could incidentally impact fish. Rather, such
    an interpretation is contrary to the treaties’
    principal purpose of opening up the region to
    settlement.
    Brief at 27–28. At oral argument, Washington even more
    forthrightly denied any treaty-based duty. Washington
    contended that it has the right, consistent with the Treaties, to
    block every salmon-bearing stream feeding into Puget Sound:
    The Court: Would the State have the right,
    consistent with the treaty, to dam every
    salmon stream into Puget Sound?
    Answer: Your honor, we would never and
    could never do that. . . .
    The Court: . . . I’m asking a different
    question. Would you have the right to do that
    under the treaty?
    Answer: Your honor, the treaty would not
    prohibit that[.]
    The Court: So, let me make sure I understand
    your answer. You’re saying, consistent with
    the treaties that Governor Stevens entered into
    with the Tribes, you could block every salmon
    stream in the Sound?
    26            UNITED STATES V. WASHINGTON
    Answer: Your honor, the treaties would not
    prohibit that[.]
    Oral Argument at 1:07–1:45, October 16, 2015.
    The State misconstrues the Treaties.
    We have long construed treaties between the United
    States and Indian tribes in favor of the Indians. Chief Justice
    Marshall wrote in the third case of the Marshall Trilogy, “The
    language used in treaties with the Indians should never be
    construed to their prejudice.” Worcester v. Georgia, 
    31 U.S. 515
    , 582 (1832). “If words be made use of which are
    susceptible of a more extended meaning than their plain
    import, as connected with the tenor of the treaty, they should
    be considered as used only in the latter sense.” 
    Id. Negotiations for
    the Stevens Treaties were conducted in
    the Chinook language, a trading jargon of only about 300
    words. Fishing 
    Vessel, 443 U.S. at 667
    n.10. The Treaties
    were written in English, a language the Indians could neither
    read nor write. Because treaty negotiations with Indians were
    conducted by “representatives skilled in diplomacy,” because
    negotiators representing the United States were “assisted by
    . . . interpreter[s] employed by themselves,” because the
    treaties were “drawn up by [the negotiators] and in their own
    language,” and because the “only knowledge of the terms in
    which the treaty is framed is that imparted to [the Indians] by
    the interpreter employed by the United States,” a “treaty must
    . . . be construed, not according to the technical meaning of its
    words to learned lawyers, but in the sense in which they
    would naturally be understood by the Indians.” Jones v.
    Meehan, 
    175 U.S. 1
    , 11 (1899). “[W]e will construe a treaty
    with the Indians as [they] understood it, and as justice and
    UNITED STATES V. WASHINGTON                   27
    reason demand, in all cases where power is exerted by the
    strong over those to whom they owe care and protection, and
    counterpoise the inequality by the superior justice which
    looks only to the substance of the right, without regard to
    technical rules.” United States v. Winans, 
    198 U.S. 371
    , 380
    (1905) (internal quotation marks omitted). “[W]e look
    beyond the written words to the larger context that frames the
    Treaty, including the history of the treaty, the negotiations,
    and the practical construction adopted by the parties.”
    Minnesota v. Mille Lacs Band of Chippewa Indians, 
    526 U.S. 172
    , 196 (1999) (internal quotation marks omitted).
    The Supreme Court has interpreted the Stevens Treaties
    on several occasions. In affirming Judge Boldt’s decision,
    the Court wrote:
    [I]t is the intention of the parties, and not
    solely that of the superior side, that must
    control any attempt to interpret the treaties.
    When Indians are involved, this Court has
    long given special meaning to this rule. It has
    held that the United States, as the party with
    the presumptively superior negotiating skills
    and superior knowledge of the language in
    which the treaty is recorded, has a
    responsibility to avoid taking advantage of the
    other side. “[T]he treaty must therefore be
    construed, not according to the technical
    meaning of its words to learned lawyers, but
    in the sense in which they would naturally be
    understood by the Indians.” Jones v. Meehan,
    
    175 U.S. 1
    , 11. This rule, in fact, has thrice
    been explicitly relied on by the Court in
    broadly interpreting these very treaties in the
    28            UNITED STATES V. WASHINGTON
    Indians’ favor. Tulee v. Washington, 
    315 U.S. 681
    [1947]; Seufort Bros. Co. v. United
    States, 
    249 U.S. 194
    [1919]; United States v.
    Winans, 
    198 U.S. 371
    [1905]. See also

    , 484 [1979].

    Washington has a remarkably one-sided view of the
    Treaties. In its brief, Washington characterizes the “treaties’
    principal purpose” as “opening up the region to settlement.”
    Brief at 29. Opening up the Northwest for white settlement
    was indeed the principal purpose of the United States. But it
    was most certainly not the principal purpose of the Indians.
    Their principal purpose was to secure a means of supporting
    themselves once the Treaties took effect.
    Salmon were a central concern. An adequate supply of
    salmon was “not much less necessary to the existence of the
    Indians than the atmosphere they breathed.” 
    Winans, 198 U.S. at 381
    . Richard White, an expert on the history of
    the American West and Professor of American History at
    Stanford University, wrote in a declaration filed in the district
    court that, during the negotiations for the Point-No-Point
    Treaty, a Skokomish Indian worried aloud about “how they
    were to feed themselves once they ceded so much land to the
    whites.” Professor White wrote, to the same effect, that
    during negotiations at Neah Bay, Makah Indians “raised
    questions about the role that fisheries were to play in their
    future.” In response to these concerns, Governor Stevens
    repeatedly assured the Indians that there always would be an
    adequate supply of fish. Professor White wrote that Stevens
    told the Indians during negotiations for the Point Elliott
    UNITED STATES V. WASHINGTON                    29
    Treaty, “I want that you shall not have simply food and drink
    now but that you may have them forever.” During
    negotiations for the Point-No-Point Treaty, Stevens said,
    “This paper is such as a man would give to his children and
    I will tell you why. This paper gives you a home. Does not
    a father give his children a home? . . . This paper secures your
    fish. Does not a father give food to his children?” Fishing
    
    Vessel, 443 U.S. at 667
    n.11 (ellipsis in original).
    The Indians did not understand the Treaties to promise
    that they would have access to their usual and accustomed
    fishing places, but with a qualification that would allow the
    government to diminish or destroy the fish runs. Governor
    Stevens did not make, and the Indians did not understand him
    to make, such a cynical and disingenuous promise. The
    Indians reasonably understood Governor Stevens to promise
    not only that they would have access to their usual and
    accustomed fishing places, but also that there would be fish
    sufficient to sustain them. They reasonably understood that
    they would have, in Stevens’ words, “food and drink . . .
    forever.” As the Supreme Court wrote in Fishing Vessels:
    Governor Stevens and his associates were
    well aware of the “sense” in which the Indians
    were likely to view assurances regarding their
    fishing rights. During the negotiations, the
    vital importance of the fish to the Indians was
    repeatedly emphasized by both sides, and the
    Governor’s promises that the treaties would
    protect that source of food and commerce
    were crucial in obtaining the Indians’ assent.
    It is absolutely clear, as Governor Stevens
    himself said, that neither he nor the Indians
    intended that the latter should be excluded
    30            UNITED STATES V. WASHINGTON
    from their ancient fisheries, and it is
    accordingly inconceivable that either party
    deliberately agreed to authorize future settlers
    to crowd the Indians out of any meaningful
    use of their accustomed places to fish.
    
    Id. at 676–77
    (citations and internal quotation marks omitted)
    (emphases added).
    Even if Governor Stevens had not explicitly promised that
    “this paper secures your fish,” and that there would be food
    “forever,” we would infer such a promise. In Winters v.
    United States, 
    207 U.S. 564
    (1908), the treaty creating the
    Fort Belknap Reservation in Montana did not include an
    explicit reservation of water for use on the reserved lands, but
    the Supreme Court inferred a reservation of water sufficient
    to support the tribe. The purpose of the treaty was to reserve
    land on which the Indians could become farmers. Without a
    reservation of water, the “lands were arid, and . . . practically
    valueless.” 
    Id. at 576.
    “[B]etween two inferences, one of
    which would support the purpose of the agreement and the
    other impair or defeat it,” the Court chose the former. 
    Id. at 577.
    Similarly, in United States v. Adair, 
    723 F.2d 1394
    (9th
    Cir. 1983), the Klamath Tribe in Oregon had entered into an
    1854 treaty under which it relinquished 12 million acres,
    reserving for itself approximately 800,000 acres. The treaty
    promised that the tribe would have the right to “hunt, fish,
    and gather on their reservation,” 
    id. at 1398,
    but contained no
    explicit reservation of water rights. A prime hunting and
    fishing area on the reservation was the Klamath Marsh,
    whose suitability for hunting and fishing depended on a flow
    of water from the Williamson River. A primary purpose of
    UNITED STATES V. WASHINGTON                    31
    the treaty was to “secure to the Tribe a continuation of its
    traditional hunting and fishing” way of living. 
    Id. at 1409.
    Because game and fish at the Klamath Marsh depended on a
    continual flow of water, the treaty’s purpose would have been
    defeated without that flow. In order to “support the purpose
    of the agreement,” 
    Winters, 207 U.S. at 577
    , we inferred a
    promise of water sufficient to ensure an adequate supply of
    game and fish. 
    Adair, 723 F.2d at 1411
    .
    Thus, even if Governor Stevens had made no explicit
    promise, we would infer, as in Winters and Adair, a promise
    to “support the purpose” of the Treaties. That is, even in the
    absence of an explicit promise, we would infer a promise that
    the number of fish would always be sufficient to provide a
    “moderate living” to the Tribes. Fishing 
    Vessel, 443 U.S. at 686
    . Just as the land on the Belknap Reservation would have
    been worthless without water to irrigate the arid land, and just
    as the right to hunt and fish on the Klamath Marsh would
    have been worthless without water to provide habitat for
    game and fish, the Tribes’ right of access to their usual and
    accustomed fishing places would be worthless without
    harvestable fish.
    In Washington III, we vacated the district court’s
    declaration of a broad and undifferentiated obligation to
    prevent environmental degradation. We did not dispute that
    the State had environmental obligations, but, in the exercise
    of discretion under the Declaratory Judgment Act, we
    declined to sustain the sweeping declaratory judgment issued
    by the district court. We wrote, “The legal standards that will
    govern the State’s precise obligations and duties under the
    treaty with respect to the myriad State actions that may affect
    the environment of the treaty area will depend for their
    definition and articulation upon concrete facts which underlie
    32            UNITED STATES V. WASHINGTON
    a dispute in a particular case.” Washington 
    III, 759 F.2d at 1357
    .
    We concluded:
    The State of Washington is bound by the
    treaty. If the State acts for the primary
    purpose or object of affecting or regulating
    the fish supply or catch in noncompliance
    with the treaty as interpreted by past
    decisions, it will be subject to immediate
    correction and remedial action by the courts.
    In other instances, the measure of the State’s
    obligation will depend for its precise legal
    formulation on all of the facts presented by a
    particular dispute.
    
    Id. There is
    no allegation in this case that in building and
    maintaining its barrier culverts the State has acted “for the
    primary purpose or object of affecting or regulating the fish
    supply or catch in noncompliance with the treaty.” The
    consequence of building and maintaining the barrier culverts
    has been to diminish the supply of fish, but this consequence
    was not the State’s “primary purpose or object.” The
    “measure of the State’s obligation” therefore depends “on all
    the facts presented” in the “particular dispute” now before us.
    The facts presented in the district court establish that
    Washington has acted affirmatively to build and maintain
    barrier culverts under its roads. The State’s barrier culverts
    within the Case Area block approximately 1,000 linear miles
    of streams suitable for salmon habitat, comprising almost
    5 million square meters. If these culverts were replaced or
    modified to allow free passage of fish, several hundred
    UNITED STATES V. WASHINGTON                   33
    thousand additional mature salmon would be produced every
    year. Many of these mature salmon would be available to the
    Tribes for harvest.
    Salmon now available for harvest are not sufficient to
    provide a “moderate living” to the Tribes. Fishing 
    Vessel, 443 U.S. at 686
    . The district court found that “[t]he reduced
    abundance of salmon and the consequent reduction in tribal
    harvests has damaged tribal economies, has left individual
    tribal members unable to earn a living by fishing, and has
    caused cultural and social harm to the Tribes in addition to
    the economic harm.” The court found, further, that “[m]any
    members of the Tribes would engage in more commercial and
    subsistence salmon fisheries if more fish were available.”
    We therefore conclude that in building and maintaining
    barrier culverts within the Case Area, Washington has
    violated, and is continuing to violate, its obligation to the
    Tribes under the Treaties.
    B. Waiver by the United States
    In the district court, Washington asserted a defense of
    “waiver and/or estoppel” based on action and inaction by the
    United States that, according to Washington, led the State to
    believe that its barrier culverts did not violate the Treaties.
    On appeal, Washington has dropped its estoppel argument,
    pressing only its waiver argument.
    Washington alleged in the district court that WSDNR had
    developed, in consultation with the United States, a 1999
    “Forest and Fish Report” that contemplated a fifteen-year
    schedule for “remediation of fish problems on forest roads”
    under the control of WSDNR. Washington alleged that it
    34            UNITED STATES V. WASHINGTON
    “reasonably concluded that by approving or failing to object
    to the State’s 15-year remediation schedule for forest roads,
    the NMFS [National Marine Fisheries Service] had
    determined that the schedule satisfied any treaty obligation.”
    Washington also alleged, with respect to “many” of the
    culverts under the control of WSDOT, that the culverts are
    “in highways funded in part by the United States,” and that
    “[t]hese highways were designed according to standards set
    or approved by the Federal Highway Administration (FHWA)
    and its predecessors.” Washington alleged that it “reasonably
    concluded that by approving or failing to object to the State’s
    culvert design and maintenance, the FHWA had determined
    that the design and maintenance satisfied any treaty
    obligation.” Washington further alleged that the Army Corps
    of Engineers, in administering the Clean Water Act, and the
    NMFS and U.S. Fish & Wildlife Service, in administering the
    Endangered Species Act, issued permits to, or failed to object
    to, WSDOT culverts, and that Washington reasonably relied
    on their action and inaction to conclude that it had satisfied
    any treaty obligations.
    The United States may abrogate treaties with Indian
    tribes, just as it may abrogate treaties with fully sovereign
    nations. However, it may abrogate a treaty with an Indian
    tribe only by an Act of Congress that “clearly express[es an]
    intent to do so.” Minnesota v. Mille Lacs Band of Chippewa
    Indians, 
    526 U.S. 172
    , 202 (1999). Congress has not
    abrogated the Stevens Treaties. So long as this is so, the
    Tribes’ rights under the fishing clause remain valid and
    enforceable. The United States, as trustee for the Tribes, may
    bring suit on their behalf to enforce the Tribes’ rights, but the
    rights belong to the Tribes.
    UNITED STATES V. WASHINGTON                    35
    The United States cannot, based on laches or estoppel,
    diminish or render unenforceable otherwise valid Indian
    treaty rights. See, e.g., Cramer v. United States, 
    261 U.S. 219
    , 234 (1923) (where Indians had treaty rights to land,
    leasing of the land to a non-Indian defendant “by agents of
    the government was . . . unauthorized and could not bind the
    government; much less could it deprive the Indians of their
    rights”); United States v. Washington, 
    157 F.3d 630
    , 649 (9th
    Cir. 1998) (“[L]aches or estoppel is not available to defeat
    Indian treaty rights.”) (quoting Swim v. Bergland, 
    696 F.2d 712
    , 718 (9th Cir. 1983)); and United States v. Ahtanum
    Irrigation Dist., 
    236 F.2d 321
    , 334 (9th Cir. 1956) (“No
    defense of laches or estoppel is available to the defendants
    here for the Government[,] as trustee for the Indian Tribe, is
    not subject to those defenses.”). The same is true for waiver.
    Because the treaty rights belong to the Tribes rather than the
    United States, it is not the prerogative of the United States to
    waive them.
    Washington argues the above line of cases has been
    “called in doubt” by City of Sherrill v. Oneida Indian Nation
    of N.Y., 
    544 U.S. 197
    (2005). Brief at 42. We disagree. Suit
    was brought in Sherrill by the Oneida Indian Nation (“OIN”),
    whose lands once comprised six million acres in central New
    York State. In 1788, in the Treaty of Fort Schuyler, OIN
    reserved 300,000 acres of its tribal land and ceded the rest to
    New York. Two years later, Congress passed the Indians
    Trade and Intercourse Act (the “Nonintercourse Act”), which
    required federal approval for the sale of tribal land. New
    York largely ignored the law and in the following years
    obtained large quantities of tribal land through treaties with
    OIN. The United States did little to stop these transactions;
    indeed, its agents took an active role in encouraging Oneidas
    to move west. By 1838, Oneidas had sold all but 5,000 acres
    36            UNITED STATES V. WASHINGTON
    of their reserved lands.     By 1920, their ownership had
    dwindled to 32 acres.
    In 1985, the Supreme Court held that the sale of OIN
    lands had been unlawful, and that the OIN was entitled to
    monetary compensation for these sales. See Cnty. of Oneida
    v. Oneida Indian Nation of N.Y. State, 
    470 U.S. 226
    (1985).
    In 1997 and 1998, OIN purchased on the open market two
    parcels of land, located within the boundaries of its ancestral
    reservation, that had been sold to a non-Indian in 1807. OIN
    claimed tribal sovereign status for the purchased parcels,
    including the sovereign right to be free of local property
    taxes. In Sherrill, the Court held against OIN, writing that
    “the Tribe cannot unilaterally revive its ancient sovereignty,
    in whole or in part, over the parcels at 
    issue.” 544 U.S. at 203
    .
    The case before us is radically different from Sherrill.
    The question in our case is not whether, as in Sherrill, a tribe
    has sovereignty over land within the boundaries of an
    abandoned reservation. The Tribes have not abandoned their
    reservations. Nor is the question whether, as in Sherrill, the
    Tribes have acted to relinquish their rights under the Treaties.
    The Tribes have done nothing to authorize the State to
    construct and maintain barrier culverts. Nor, finally, is the
    question whether, as in Sherrill, to allow the revival of
    disputes or claims that have long been left dormant. As
    described above, Washington and the Tribes have been in a
    more or less continuous state of conflict over treaty-based
    fishing rights for over one hundred years.
    UNITED STATES V. WASHINGTON                     37
    C. Washington’s Cross-Request
    Washington asserted a “cross-request” (in effect, a
    counterclaim) based on the United States’ construction and
    maintenance of barrier culverts on its own land. Washington
    contended that if its barrier culverts violate the Treaties, so
    too do the United States’ barrier culverts. Washington
    contended that an injunction requiring it to correct its barrier
    culverts, while leaving undisturbed those of the United States,
    imposed a disproportionate and therefore unfair burden on the
    State. Washington sought an injunction that would require
    the United States “to fix and thereafter maintain all culverts
    built or maintained by [the United States] . . . before the State
    of Washington is required to repair or remove any of its
    culverts.”
    The district court struck the cross-request and
    subsequently denied Washington’s motion to amend. It did
    so on two grounds. First, it held that Washington’s cross-
    request was barred by sovereign immunity. Second, it held
    that Washington did not have standing to assert treaty rights
    belonging to the Tribes. We agree with both grounds.
    1. Sovereign Immunity
    The United States enjoys sovereign immunity from
    unconsented suits. However, when the United States files
    suit, consent to counterclaims seeking offset or recoupment
    will be inferred. United States v. Agnew, 
    423 F.2d 513
    , 514
    (9th Cir. 1970). Washington contends that the injunction it
    seeks against the United States is “recoupment.” We
    disagree.
    38            UNITED STATES V. WASHINGTON
    The Tenth Circuit has set forth three criteria that must be
    satisfied for a recoupment claim:
    To constitute a claim in recoupment, a
    defendant’s claim must (1) arise from the
    same transaction or occurrence as the
    plaintiff’s suit; (2) seek relief of the same kind
    or nature as the plaintiff’s suit; and (3) seek an
    amount not in excess of the plaintiff’s claim.
    Berrey v. Asarco Inc., 
    439 F.3d 636
    , 645 (10th Cir. 2006); see
    Fed. Deposit Insur. Corp. v. Hulsey, 
    22 F.3d 1472
    , 1487
    (10th Cir. 1994). We adopt these criteria as our own, and
    make explicit that the remedy (the “amount”) sought by the
    United States and by the defendant in recoupment must be
    monetary.
    It is implicit in the use of the word “amount” in Berrey’s
    third criterion that a recoupment claim is a monetary claim.
    A claim for recoupment, if successful, can reduce or
    eliminate the amount of money that would otherwise be
    awarded to the plaintiff. It cannot result in an affirmative
    monetary judgment in favor of the party asserting the claim:
    “Although a counterclaim may be asserted against a
    sovereign by way of set off or recoupment to defeat or
    diminish the sovereign’s recovery, no affirmative relief may
    be given against a sovereign in the absence of consent.”
    
    Agnew, 423 F.2d at 514
    ; see also United States v. U.S. Fid. &
    Guar. Co., 
    309 U.S. 506
    , 511 (1940) (“[A] defendant may,
    without statutory authority, recoup on a counterclaim an
    amount equal to the principal claim.”); Black’s Law
    Dictionary 1466 (10th ed. 2009) (“Recoupment: 1. The
    getting back or regaining of something, esp. expenses. 2. The
    withholding, for equitable reasons, of all or part of something
    UNITED STATES V. WASHINGTON                    39
    that is due. . . . 3. Reduction of a plaintiff’s damages because
    of a demand by the defendant arising out of the same
    transaction. . . . 4. The right of a defendant to have the
    plaintiff’s claim reduced or eliminated because of the
    plaintiff’s breach of contract or duty in the same
    transaction.”). The parties have cited no case, and we have
    found none, in which the term recoupment has been applied
    to non-monetary relief such as an injunction.
    Washington’s cross-request for an injunction thus does
    not qualify as a claim for recoupment and is barred by
    sovereign immunity.
    2. Standing
    Washington seeks an injunction requiring the United
    States to correct its barrier culverts on the ground that the
    United States is bound by the Treaties in the same manner
    and to the same degree as the State. Washington is, of
    course, correct that the United States is bound by the Treaties.
    Indian treaty rights were “intended to be continuing against
    the United States . . . as well as against the state[.]” 
    Winans, 198 U.S. at 381
    –82. Our holding that Washington has
    violated the Treaties in building and maintaining its barrier
    culverts necessarily means that the United States has also
    violated the Treaties in building and maintaining its own
    barrier culverts.
    However, any violation of the Treaties by the United
    States violates rights held by the Tribes rather than the State.
    The Tribes have not sought redress against the United States
    in the proceeding now before us.
    40            UNITED STATES V. WASHINGTON
    D. Injunction
    The district court held a trial in 2009 and 2010 to
    determine the appropriate remedy for Washington’s violation
    of the Treaties. At the time of trial, there were 1,114 state-
    owned culverts in the Case Area. At least 886 of them
    blocked access to “significant habitat,” defined as 200 linear
    meters or more of salmon habitat upstream from the culvert
    to the first natural passage barrier. More barrier culverts were
    identified or constructed within the Case Area after 2009.
    The court estimated in its 2013 Memorandum and Decision
    that at the then-current rate of remediation, all of the barrier
    culverts under the control of WSDNR, State Parks, and
    WDFW would be corrected by October 31, 2016. The great
    majority of barrier culverts, however, were under WSDOT’s
    control. In 2009, when trial began, there were 807 identified
    WSDOT barrier culverts. Additional WSDOT barrier
    culverts were constructed or identified after that date.
    In 1997, WDFW and WSDOT reported to the Washington
    State legislature that WSDOT culverts blocked 249 linear
    miles of stream, comprising over 1.6 million square meters of
    salmon habitat, which they estimated was sufficient to
    produce 200,000 adult salmon per year. Based on WDFW
    records, the district court found that at the time of trial, state-
    owned barrier culverts in the Case Area blocked access to
    approximately 1,000 miles of stream, comprising almost
    5 million square meters of salmon habitat.
    The district court issued a permanent injunction in 2013,
    on the same day it issued its Memorandum and Decision.
    The court ordered the State, in consultation with the Tribes
    and the United States, to prepare within six months a current
    list of all state-owned barrier culverts within the Case Area.
    UNITED STATES V. WASHINGTON                    41
    The court ordered that identification of a culvert as a
    “barrier” be based on the methodology specified in the Fish
    Passage Barrier and Surface Water Diversion Screening and
    Prioritization Manual (“Assessment Manual”) published by
    WDFW in 2000. The court ordered WSDNR, State Parks,
    and WDFW to provide fish passage through all their barrier
    culverts on the list by October 31, 2016 — the date by which
    these three agencies were already expected to complete
    correction of their barrier culverts.
    For barrier culverts under the control of WSDOT, the
    injunction was more nuanced. In Paragraph 6 of the
    injunction, the court ordered WSDOT to provide, within
    seventeen years of the date of the order, and “in accordance
    with the standards set out in this injunction,” fish passage for
    each barrier culvert with more than 200 linear meters of
    salmon habitat upstream to the first natural passage barrier.
    In Paragraph 7, the court ordered WSDOT to replace existing
    barrier culverts above which there was less than 200 linear
    meters of accessible salmon habitat only at the “end of the
    useful life” of the culverts, or sooner “as part of a highway
    project.” In Paragraph 8, the court allowed WSDOT to defer
    correction of some of the culverts described in Paragraph 6.
    Deferred culverts can account for up to ten percent of
    upstream habitat from the culverts described in Paragraph 6.
    WSDOT’s choice of which culverts to defer is to be made in
    consultation with the Tribes and the United States. The court
    specified that the choice of culverts could be guided by the
    “Priority Index” methodology described in the WDFD
    Assessment Manual. That methodology uses cost as a
    permissible factor in determining priority. Assessment
    Manual at 55. Culverts deferred under Paragraph 8 are to be
    replaced on the more lenient schedule specified in Paragraph
    7.
    42             UNITED STATES V. WASHINGTON
    In Paragraph 9, the district court ordered that the State
    shall design and build fish passage at each
    barrier culvert on the List in order to pass all
    species of salmon at all life stages at all flows
    where the fish would naturally seek passage.
    In order of preference, fish passage shall be
    achieved by (a) avoiding the necessity for the
    roadway to cross the stream, (b) use of full
    span bridge, (c) use of the “stream
    simulation” methodology . . . which the
    parties to this proceeding have agreed
    represents the best science currently available
    for designing culverts that provide fish
    passage and allow fluvial processes. Nothing
    in this injunction shall prevent the [State]
    from developing and using designs other than
    bridges or stream simulation in the future if
    the [State] can demonstrate that those future
    designs provide equivalent or better fish
    passage and fisheries habitat benefits than the
    designs required in this injunction.
    In Paragraph 10, the court provided that the State may deviate
    from the design standards specified in Paragraph 9 in cases of
    emergency or where “extraordinary site conditions” exist.
    The court specified that it would “retain continuing
    jurisdiction . . . for a sufficient period to assure that the
    [State] compl[ies] with the terms of this injunction.”
    Washington declined to participate in the formulation of
    the injunction on the ground that it had not violated the
    Treaties and that, therefore, no remedy was appropriate.
    Washington now objects on several grounds to the injunction
    UNITED STATES V. WASHINGTON                      43
    that was formulated without its participation. Washington
    specifically objects (1) that the injunction is too “broad,”
    Brief at 50; (2) that the district court did not “defer to the
    State’s expertise,” 
    id. at 54;
    (3) that the court did not properly
    consider costs and equitable principles, 
    id. at 57;
    (4) and that
    the injunction “impermissibly and significantly intrudes into
    state government operations.” 
    Id. at 63.
    Finally, Washington
    objects that its four specific objections support a contention
    that the court’s injunction is inconsistent with “federalism
    principles.” 
    Id. at 47,
    65. We consider the State’s objections
    in turn.
    1. Breadth of the Injunction
    Washington contends in its brief that “[t]he Tribes
    presented no evidence that state-owned culverts are a
    significant cause of the decline [in salmon]. . . . Despite that
    complete failure of proof, the district court found that state-
    owned culverts ‘have a significant total impact on salmon
    production.’” Brief at 50 (emphasis in original). Washington
    contends, further, that the district court “ordered replacement
    of nearly every state-owned barrier culvert within the case
    area without any specific showing that those culverts have
    significantly diminished fish runs or tribal fisheries, or that
    replacing them will meaningfully improve runs.” 
    Id. Washington misrepresents
    the evidence                     and
    mischaracterizes the district court’s order.
    Contrary to the State’s contention, the Tribes presented
    extensive evidence in support of the court’s conclusion that
    state-owned barrier culverts have a significant adverse effect
    on salmon. The 1997 report prepared for the Washington
    State Legislature by two of the defendants in this case,
    44            UNITED STATES V. WASHINGTON
    WDFW and WSDOT, stated, “Fish passage at human made
    barriers such as road culverts is one of the most recurrent and
    correctable obstacles to healthy salmonid stocks in
    Washington.” The report concluded:
    A total potential spawning and rearing area of
    1,619,839 m2 (249 linear miles) is currently
    blocked by WSDOT culverts on the 177
    surveyed streams requiring barrier resolution;
    this is enough wetted stream area to produce
    200,000 adult salmonid annually. These
    estimates would all increase when considering
    the additional 186 barriers that did not have
    full habitat assessments.
    The report recommended that state funding be supplied to
    remove “all barriers” under the control of the State:
    Planning is underway for resolution of at least
    seven more barriers during the 1997–99
    biennium using dedicated funds, and to
    resolve all barriers in the next two or three
    decades. . . . Estimated cost is about $40
    million, with resultant benefits exceeding
    $160 million.
    Based on later WDFW figures, the district court found
    that at the time of trial state-owned barrier culverts in the
    Case Area blocked access to approximately 1,000 linear miles
    of stream, comprising almost 5 million square meters of
    salmon habitat. These figures, taken together with the 1997
    figures supplied by WDFW and WSDOT, indicate that the
    total habitat blocked by state-owned barrier culverts in the
    UNITED STATES V. WASHINGTON                   45
    Case Area is capable of producing several times the 200,000
    mature salmon specified in the 1997 report.
    Witnesses at trial repeatedly described benefits to salmon
    resulting from correction of barrier culverts. One example is
    evidence presented by Mike McHenry, habitat program
    manager for the Lower Elwha Klallam Tribe. In his written
    testimony, McHenry described several studies. One was a
    2003 study of culvert removal projects on the Stillaguamish
    River that opened up 19 linear kilometers of salmon habitat.
    According to the study, over 250 adult coho salmon were
    observed spawning in the newly accessible habitat in each of
    the two years immediately after the completion of the
    projects. Based on his own experience as habitat manager for
    the tribe, McHenry wrote that removal of barrier culverts on
    the Lower Elwha River had had a similar effect. In
    McHenry’s view, “The systematic correction of barrier
    culverts is an important place to focus restoration efforts.”
    He wrote, further, “The correction of human caused barriers
    is generally recognized as the second highest priority for
    restoring habitats used by Pacific salmon (following the
    protection of existing functional habitats).”
    In his live testimony, McHenry stated that his tribe had
    corrected seventeen of thirty-one barriers in a particular
    watershed:
    McHenry:       Because when we did the
    watershed assessment, we found that there
    were 50 miles of historically active stream
    that salmon could access in this watershed,
    and fully half that mileage was blocked by
    culverts of various ownerships. So to us, we
    applied our scientific knowledge and
    46          UNITED STATES V. WASHINGTON
    recommendations from the literature which
    indicated that when you’re going to restore a
    place like this, you need to go after the
    barriers first.
    The Court: In your expert opinion, that was
    the biggest bang for your buck?
    McHenry: Yes.
    Another example is the live testimony of Lawrence
    Wasserman, environmental policy manager for the
    Swinomish Indian Tribal Community. He testified that
    culvert remediation provides substantial benefits:
    There’s an immediate access and
    immediate benefit to additional habitat when
    we replace a culvert . . . .
    If you compare that to having to plant
    trees, shade, it can take 10, 20, 50 years to get
    the trees large enough . . . .
    . . . We have a high confidence in design.
    By and large, we know how to fix
    culverts. . . . So we have a high confidence
    compared to many other more experimental
    restoration activities.
    It’s fairly easy to monitor. If there were
    no fish there before, [then] we open a culvert
    and we can count fish[.] . . .
    UNITED STATES V. WASHINGTON                    47
    A critical factor is that there’s minimal
    impacts on adjacent land use or land
    owners. . . . [I]t’s relatively infrequent where
    there needs to be a condemnation of other
    people’s land or asking people to sell their
    land. . . .
    . . . It’s cost effective. There have been
    some studies that have shown that, really,
    compared to other kinds of restoration
    activities, the cost per smolt produced is
    relatively low[.] . . .
    And finally, we get benefits with a broad
    sweep of culvert repairs. We get a very broad
    geographic distribution of benefits, and the
    cumulative effects can accrue across a variety
    of watersheds.
    It is true, as the evidence at trial showed, that correction
    of barrier culverts is only one of a number of measures that
    can usefully be taken to increase salmon production in the
    Case Area. It is also true that the benefits of culvert
    correction differ depending on the culvert in question. For
    example, Paul Wagner, manager of the culvert correction
    program for WSDOT, presented evidence in 2013 identifying
    817 WSDOT barrier culverts blocking 937 linear miles of
    stream habitat in the Case Area. Wagner’s evidence showed
    that correction of the 314 culverts blocking the most habitat
    would open up 655 of the 937 miles of total habitat.
    Correcting the 232 culverts blocking the least habitat would
    open up only 95 miles. Those 95 miles of habitat constitute
    10.1 percent of the total habitat blocked by the 817 barrier
    48            UNITED STATES V. WASHINGTON
    culverts. The 232 culverts blocking those 95 miles
    constituted 28.4 percent of the total barrier culverts.
    The district court’s injunction took into account the facts
    that culvert correction is not the only factor in salmon
    recovery; that some culverts block more habitat than others;
    and that some culverts are more expensive to correct than
    others. The court ordered correction of high-priority culverts
    — those blocking 200 linear meters or more of upstream
    habitat — within seventeen years. For low-priority culverts
    — those blocking less than 200 linear meters of upstream
    habitat — the court ordered correction only at the end of the
    useful life of the existing culvert, or when an independently
    undertaken highway project would require replacement of the
    culvert. Further, recognizing the likelihood that accelerated
    replacement of some high-priority culverts will not be cost-
    effective, the court allowed the State to defer correction of
    high-priority culverts accounting for up to ten percent of the
    total blocked upstream habitat, and to correct those culverts
    on the more lenient schedule of the low-priority culverts.
    Wagner’s evidence indicates that if the sole criterion for
    choosing deferred culverts is the amount of blocked habitat,
    there will be approximately 230 deferred culverts. If cost of
    correction of particular culverts is added as a criterion, there
    will be a somewhat smaller number of deferred culverts.
    In sum, we disagree with Washington’s contention that
    the Tribes “presented no evidence,” and that there was a
    “complete failure of proof,” that state-owned barrier culverts
    have a substantial adverse effect on salmon. The record
    contains extensive evidence, much of it from the State itself,
    that the State’s barrier culverts have such an effect. We also
    disagree with Washington’s contention that the court ordered
    correction of “nearly every state-owned barrier culvert”
    UNITED STATES V. WASHINGTON                      49
    without “any specific showing” that such correction will
    “meaningfully improve runs.” The State’s own evidence
    shows that hundreds of thousands of adult salmon will be
    produced by opening up the salmon habitat that is currently
    blocked by the State’s barrier culverts. Finally, we disagree
    with Washington’s contention that the court’s injunction
    indiscriminately orders correction of “nearly every state-
    owned barrier culvert” in the Case Area. The court’s order
    carefully distinguishes between high- and low-priority
    culverts based on the amount of upstream habitat culvert
    correction will open up. The order then allows for a further
    distinction, to be drawn by WSDOT in consultation with the
    United States and the Tribes, between those high-priority
    culverts that must be corrected within seventeen years and
    those that may be corrected on the more lenient schedule
    applicable to the low-priority culverts.
    2. Deference to the State’s Expertise
    Washington contends that the district court made a clearly
    erroneous finding of fact, concluding that correction of
    human-caused barriers is the highest priority in habitat
    restoration. It contends, further, that this finding led the court
    to ignore the expert testimony presented by both the State and
    the Tribes. Washington wrote in its brief:
    The State has concluded — and the Tribes
    agree — that a comprehensive approach to
    preserving and restoring salmon runs is the
    most productive and cost-effective . . . . The
    district court concluded, however, that
    “correction of human-caused barriers is
    recognized as the highest priority for restoring
    salmon habitat in the Case Area.” On that
    50            UNITED STATES V. WASHINGTON
    basis, the court ordered injunctive relief
    focused solely on culverts, even though the
    cost of the injunction will likely reduce
    funding available for other salmon restoration
    efforts. The court’s finding was clearly
    erroneous, and its approach was an abuse of
    discretion.
    In concluding that fixing culverts is “the
    highest priority for restoring salmon habitat in
    the Case Area,” the court cited the declaration
    of tribal expert Mike McHenry.             Mr.
    McHenry said no such thing.
    Brief at 54–55.
    Washington is mistaken. It is true that the district court
    made the factual finding to which Washington objects. Citing
    McHenry’s evidence, the court wrote, “The correction of
    human-caused barriers is recognized as the highest priority
    for restoring salmon habitat in the Case Area.” But the
    court’s finding is amply supported by the record. With
    respect to restoring habitat (as distinct from preserving
    habitat, which has a higher priority), McHenry wrote that it
    is “generally recognized” that the correction of human-caused
    barriers is the highest priority. Further, McHenry testified
    that “you need to go after the barriers first” because that is the
    “biggest bang for the buck.” Wasserman testified to the same
    effect, saying that “there’s an immediate access and
    immediate benefit to additional habitat when we replace a
    culvert”; that “it’s cost effective” compared to “other kinds of
    restoration activities”; and that “the cumulative effects can
    accrue across a variety of watersheds.”
    UNITED STATES V. WASHINGTON                     51
    It is also true that the district court’s injunction “focused
    solely on culverts” and did not order other remedies. But it
    is appropriate that the injunction should have done so. The
    court was acutely conscious of the fact that, while barrier
    culverts are an important cause of the decline of salmon in the
    Case Area, they are not the only cause. It wrote, “A primary
    cause of this decline is habitat degradation . . . . One cause
    of the degradation of salmon habitat is blocked culverts[.]”
    (Emphasis added.) However, because the only treaty
    violation alleged in this litigation was Washington’s barrier
    culverts, the court acted appropriately in ordering only the
    correction of these culverts. As the court wrote, “The scope
    of this subproceeding includes only those culverts that block
    fish passage under State-owned roads.”
    Contrary to Washington’s contention, the district court
    had a sophisticated record-based understanding of the various
    causes of the decline of salmon in the Case Area, of what
    could be achieved by the correction of state-owned barrier
    culverts, and of the limitations on what could be achieved by
    culvert correction. The court’s injunction is carefully crafted
    to reflect that understanding.
    3. Costs and Equitable Principles
    Washington contends that the district court’s injunction
    fails properly to take costs into account, and that its
    injunction is inconsistent with equitable principles.
    a. Costs
    Washington writes in its brief that correction of WSDOT
    barrier culverts will cost approximately $1.88 billion over the
    course of the seventeen-year schedule ordered by the court,
    52           UNITED STATES V. WASHINGTON
    or “roughly $117 million per year of the injunction.” (Using
    Washington’s own estimates, a correct calculation is actually
    $110.6 million per year rather than $117 million.)
    Washington’s estimated total cost is based on an assumption
    of 817 corrected culverts, at an average correction cost of
    $2.3 million per culvert.
    Washington’s cost estimates are not supported by the
    evidence. Washington contended at trial, as it now contends
    to us, that the average cost to replace a WSDOT barrier
    culvert would be $2.3 million. But the district court did not
    accept this estimate. The court found that “the actual cost of
    construction for twelve WSDOT stream simulation culvert
    projects completed prior to the 2009 trial ranged from
    $413,000 to $1,674,411; the average cost for the twelve was
    $658,639 each.” In 2013, the State submitted a declaration
    from WSDOT official Wagner listing thirty-one culvert
    correction projects completed state-wide since October 2009.
    Of these, twenty-four used either a stream simulation design
    or a bridge. The declaration stated that the average cost for
    each these twenty-four projects was $1,827,168, not
    $2,300,000 as the State now contends. The district court
    noted that even Wagner’s lower figure could not be
    confirmed because cost data was missing for eight of the
    twenty-four projects.
    There are additional reasons to disregard the State’s
    estimate of total cost. First, Washington assumes that all 817
    of the state-owned barrier culverts will be corrected on the
    seventeen-year schedule. This is demonstrably incorrect.
    According to the State’s own evidence, Paragraph 8 of the
    injunction will allow the State to defer correction of
    approximately 230 of the 817 culverts. If cost of barrier
    correction (rather than merely amount of upstream habitat) is
    UNITED STATES V. WASHINGTON                     53
    taken into account in deciding which culverts to defer, fewer
    but more costly culverts will be deferred. Second, and
    perhaps more important, Washington must eventually correct
    its barrier culverts, irrespective of the court’s order in this
    suit. The district court wrote that federal and state law
    require Washington to correct its barrier culverts “in any
    case,” and that the only consequence of its order will be an
    “acceleration of barrier correction.” The net costs imposed
    on Washington by the injunction are thus not the full costs of
    barrier correction, but rather only the “marginal costs
    attributable to an accelerated culvert correction schedule.”
    Finally, we note that a portion of WSDOT’s funding for
    correcting its barrier culverts will come from the United
    States. The court wrote, “[T]he state expects to receive over
    $22,000,000 for fish passage barrier projects from the federal
    government in the years 2011 to 2017. Of this amount,
    $15,813,000 is expected in the 2013–2015 biennium.”
    b. Equitable Principles
    Washington makes one specific objection based on
    equitable principles. It objects that the court abused its
    discretion in requiring that “the State alone,” rather than State
    in conjunction with the United States, be “burdened with the
    entire cost of culvert repair.” Brief at 63. We disagree. The
    court’s order required correction of only those barrier culverts
    that were built and maintained by the State. It was not an
    abuse of discretion to require the State to pay for correction
    of its own barrier culverts.
    Further, we note more generally that the district court did
    consider equitable principles, and concluded that those
    54           UNITED STATES V. WASHINGTON
    principles favored the Tribes and the citizens of the State.
    The court wrote:
    The Tribes and their individual members
    have been harmed economically, socially,
    educationally, and culturally by the greatly
    reduced salmon harvests that have resulted
    from State-created or State-maintained fish
    passage barriers.
    This injury is ongoing, as efforts by the
    State to correct the barrier culverts have been
    insufficient. . . . Remedies at law are
    inadequate as monetary damages will not
    adequately compensate the Tribes and their
    individual members for these harms. . . .
    The balance of hardships tips steeply
    toward the Tribes in this matter. The promise
    made to the Tribes that the Stevens Treaties
    would protect their source of food and
    commerce was crucial in obtaining their
    assent to the Treaties’ provisions. . . . Equity
    favors requiring the State of Washington to
    keep the promises upon which the Tribes
    relied when they ceded huge tracts of land by
    way of the Treaties.
    ...
    The public interest will not be disserved
    by an injunction. To the contrary, it is in the
    public’s interest, as well as the Tribes’ to
    accelerate the pace of barrier correction. All
    UNITED STATES V. WASHINGTON                     55
    fishermen, not just Tribal fishermen, will
    benefit from the increased production of
    salmon. . . . The general public will benefit
    from the enhancement of the resource and the
    increased economic return from fishing in the
    State of Washington. The general public will
    also benefit from the environmental benefits
    of salmon habitat restoration.
    4. Intrusion into State Government Operations
    Washington contends that the court’s order
    “impermissibly and significantly intrudes into state
    government operations.” Brief at 63. Washington contends
    that it “was making great strides in repairing culverts before
    any federal court intervention,” and that “there was no need
    for the court to issue a detailed and expensive injunction that
    sets an inflexible and tight schedule for culvert repair.” 
    Id. at 63–64.
    Washington implies that the cost of complying with
    the court’s order will oblige the State to cut other important
    state programs:
    [T]he injunction will require the State to
    devote roughly $100 million per year more
    than it otherwise would have to culvert repair.
    This at a time when the State faces recurring
    budget shortfalls in the billions of dollars and
    has already made deep and painful cuts to
    subsidized health insurance for low income
    workers, K-12 schools, higher education, and
    basic aid for persons unable to work.
    
    Id. at 58.
    We disagree.
    56            UNITED STATES V. WASHINGTON
    The district court disagreed with Washington’s contention
    that there was “no need” for the court to order correction of
    its barrier culverts. Based on the State’s slow rate of barrier
    correction, the court concluded that “under the current State
    approach, the problem of WSDOT barrier culverts in the Case
    Area will never be solved.” The district court also disagreed
    with the Washington’s cost estimates. As seen above,
    Washington’s estimate of its cost to comply with the court’s
    order (“roughly $100 million per year” more than it would
    otherwise spend) is dramatically overstated.
    The district court carefully considered the marginal cost
    imposed on Washington by its injunction and concluded that
    the State could comply with the order without cutting vital
    state programs. The court relied on a state budget document
    showing that $9.9 billion was allocated to the state
    transportation budget for the 2011–2013 biennium. Of that
    $9.9 billion, $7.88 billion was allocated to WSDOT. Noting
    the separation of the transportation budget from other state
    budgets, the court concluded, “The separation of the
    Transportation Budget from the Operating and Capital
    Budgets ensures that money will not be taken from education,
    social services, or other vital State functions to fund culvert
    repairs.”
    5. Federalism Principles
    Washington contends, based on the four specific
    objections just reviewed, that the district court’s injunction
    violates principles of federalism. Washington asserts four
    principles of federalism:
    First, the remedy must be no broader than
    necessary to address the federal law violation.
    UNITED STATES V. WASHINGTON                    57
    Second, courts must grant deference to a
    state’s institutional competence and subject
    matter expertise. Third, courts must take cost
    into consideration and not substitute their
    budgetary judgment for that of the state. And
    finally, relief must be fashioned so that it is
    the least intrusive into state governmental
    affairs. The district court’s injunction here
    contravenes all of these principles.
    Blue Brief at 49. We will not quarrel here with these
    principles, stated at this level of generality. However, for the
    reasons given above, we have concluded that the district
    court’s injunction violates none of them.
    Further, a federalism-based objection to an injunction
    enforcing Indian treaty rights should not be viewed in the
    same light as an objection to a more conventional structural
    injunction. Washington cites two Supreme Court cases in
    support of its federalism objection — Rizzo v. Goode,
    
    423 U.S. 362
    (1976) (structural injunction requiring reform
    of the Philadelphia police department), and Horne v. Flores,
    
    557 U.S. 433
    (2009) (structural injunctions requiring Arizona
    to comply with Equal Educational Opportunities Act of
    1974). However, Washington fails to cite the Supreme Court
    case directly on point — Fishing Vessel, 
    443 U.S. 658
    (1979)
    — in which the Court affirmed detailed injunctions requiring
    Washington to comply with the very Treaties at issue in this
    case.
    The district court in Fishing Vessel had entered a series of
    detailed injunctions implementing its holding that the Treaties
    entitled the Tribes to take up to fifty percent of harvestable
    salmon in any given year. Washington strenuously resisted,
    58            UNITED STATES V. WASHINGTON
    with the result that the district court effectively took over
    much of the State’s management of the salmon fishery.
    Washington objected both to the district court’s interpretation
    of the Treaties, and to the court’s intrusion into its affairs.
    The Supreme Court affirmed the district court’s holding on
    the meaning of the Treaties. It then rejected, in no uncertain
    terms, federalism-based objections to the injunctions
    enforcing the Treaties:
    Whether [Washington] Game and
    Fisheries may be ordered actually to
    promulgate regulations having effect as a
    matter of state law may well be doubtful. But
    the District Court may prescind that problem
    by assuming direct supervision of the fisheries
    if state recalcitrance or state-law barriers
    should be continued. It is therefore absurd to
    argue . . . both that the state agencies may not
    be ordered to implement the decree and also
    that the District Court may not itself issue
    detailed remedial orders as a substitute for
    state supervision.
    Fishing 
    Vessel, 443 U.S. at 695
    (emphasis added).
    6. Modification of the Injunction
    It is possible that changing or newly revealed facts or
    circumstances will affect the fairness or efficacy of an
    injunction. In the case before us, the district court has
    ordered that many of WSDOT’s high-priority barrier culverts
    be corrected over the course of seventeen years, and that the
    remainder be corrected only at the end of the culvert’s natural
    life or when road work undertaken for independent reasons
    UNITED STATES V. WASHINGTON                     59
    would in any event require replacement of the culvert. It is
    possible that, during this extended period, changed or newly
    revealed facts or circumstances will justify a modification of
    the injunction. The district court should not hesitate to
    modify its injunction if this proves to be the case. As the
    Supreme Court wrote in System Federation No. 91 v. Wright,
    
    364 U.S. 642
    , 647 (1961), “a sound judicial discretion may
    call for the modification of the terms of an injunctive decree
    if the circumstances, whether of law or fact, obtaining at the
    time of its issuance have changed, or new ones have since
    arisen.” See also Rufo v. Inmates of Suffolk Cnty. Jail,
    
    502 U.S. 367
    , 380–81 (1992). In affirming the judgment
    entered by the district court in this case, we emphasize that
    the flexibility inherent in equity jurisdiction allows the court,
    if changed or newly revealed facts or circumstances warrant,
    to modify its injunction accordingly.
    Conclusion
    In sum, we conclude that in building and maintaining
    barrier culverts Washington has violated, and continues to
    violate, its obligation to the Tribes under the fishing clause of
    the Treaties. The United States has not waived the rights of
    the Tribes under the Treaties, and has not waived its own
    sovereign immunity by bringing suit on behalf of the Tribes.
    The district court did not abuse its discretion in enjoining
    Washington to correct most of its high-priority barrier
    culverts within seventeen years, and to correct the remainder
    at the end of their natural life or in the course of a road
    construction project undertaken for independent reasons.
    AFFIRMED.
