    Opinion by Judge Thomas
    4         PYRAMID LAKE PAIUTE TRIBE V. NEVADA
    SUMMARY*
    Water Rights
    Affirming the district court’s judgment, the panel held
    that the district court correctly concluded that diversion of
    water for waterfowl habitat is not “irrigation” within the
    meaning of the federal court Alpine decree governing water
    rights in the Newlands Reclamation Project.
    This appeal concerns applications filed by the Nevada
    Department of Wildlife and the Nevada Waterfowl
    Association to transfer water rights from agricultural land in
    the Newlands Project to the Carson Lake and Pasture, a
    wildlife refuge located within the Lahontan Valley wetlands
    at the terminus of the Carson River. Because the applicants
    proposed to use the transferred water to support the growth of
    plants used by wildlife, they argued that the intended use of
    water at Carson Lake and Pasture constituted irrigation. The
    Pyramid Lake Paiute Tribe and the United States protested
    the applications.
    Determining that the Tribe had standing, the panel held
    that both the Alpine Decree and the Nevada water code speak
    of irrigation solely in the context of agriculture and
    distinguish such use from the application of water for
    recreational, aesthetic, and wildlife purposes. Therefore, the
    panel agreed with the district court that the State Engineer’s
    approval of the applications to transfer the non-consumptive
    use portion of the applicants’ water rights violated

    OPINION
    THOMAS, Circuit Judge:
    Almost from the time that explorers John C. Frémont and
    Kit Carson first came upon the Truckee River and Pyramid
    Lake,1 disputes have arisen about water rights. In this latest
    chapter in a hundred-year litigation history, see Nevada v.
    United States, 
    463 U.S. 110
    , 113 (1983) (summarizing
    history), we consider whether diverting water to wetlands in
    order to sustain wildlife habitat constitutes “irrigation.” We
    conclude that, within the meaning of the federal court decree
    governing water rights in the Newlands Reclamation Project,
    it does not, and we affirm the judgment of the district court.
    I
    Two rivers flow through the Truckee River Basin, which
    straddles the California-Nevada border in one of the nation’s
    most arid regions: the Truckee and the Carson. The Carson
    River “rises on the eastern slope of the High Sierra in Alpine
    County, California, and flows north and northeast over a
    course of about 170 miles, finally disappearing into Carson
    sink.” 
    Id. at 115
    . The Truckee River originates in Lake
    Tahoe, flows north and east into Nevada, and terminates in
    1
    Frémont named the lake after a pyramid-shaped island in it. Arthur C.
    Benke and Colbert E. Cushing, Rivers of North America 3 (2005). He and
    Carson originally named the Truckee River as the Salmon Trout River
    after the huge Lahontan cutthroat trout that ran up the river from Pyramid
    Lake to spawn. The river was ultimately named after a Paiute chief. State
    of Nevada Division of Water Resources, A Chronological History of Lake
    Tahoe and the Truckee River and Related Water Issues (2013), available

    PYRAMID LAKE PAIUTE TRIBE V. NEVADA                7
    Pyramid Lake, for which it provides the sole source of water.
    United States v. Alpine Land & Reservoir Co., 
    878 F.2d 1217
    ,
    1219 (9th Cir. 1989) (Alpine II).
    Pyramid Lake is “widely considered the most beautiful
    desert lake in North America . . . .” Nevada, 
    463 U.S. at 114
    (internal quotation marks and citation omitted). It lies
    entirely within the reservation of the Pyramid Lake Paiute
    Tribe (the “Tribe”) and is the Tribe’s “aboriginal home.”
    Alpine II, 
    878 F.2d at 1219
    . Historically, Pyramid Lake
    supported a world-famous fishery of Lahontan cutthroat trout
    and cui-ui sucker fish. Nevada, 
    463 U.S. at 114-15
    , 119 n.7.
    Over the course of the twentieth century, however, diversion
    of Truckee River water for agricultural use caused a dramatic
    reduction in the lake’s surface area. Alpine II, 
    878 F.2d at 1220
    . As a result, a delta formed at the mouth of the Truckee
    River, choking off access to spawning grounds used by
    Pyramid Lake’s native fish populations and driving them to
    the brink of extinction. 
    Id.
    The large-scale diversion of water for agricultural use in
    the Truckee River basin is facilitated by the Newlands Project
    (the “Project”), one of the first federal reclamation efforts
    commenced under the authority of the Reclamation Act of
    1902, ch. 1093, 
    32 Stat. 388
    , codified at 
    43 U.S.C. §§ 371
    –600e. The Reclamation Act gave the federal
    government “a prominent role in the development of the
    West,” by authorizing the Secretary of the Interior “to
    withdraw from public entry lands in specified western States,
    reclaim the lands through irrigation projects, and then to
    restore the lands to entry pursuant to the homestead laws and
    certain conditions imposed by the Act itself.” Nevada,
    
    463 U.S. at 115
    . Pursuant to this authority, the Secretary
    withdrew from the public domain approximately 232,800
    8        PYRAMID LAKE PAIUTE TRIBE V. NEVADA
    acres of land in western Nevada to establish the Newlands
    Project. United States v. Alpine Land & Reservoir Co.,
    
    291 F.3d 1062
    , 1066 (9th Cir. 2002) (Alpine V). The Project
    “was designed to irrigate a substantial amount of this land
    with water from the Truckee and Carson Rivers, thereby
    turning wasteland into farmland.” Alpine II, 
    878 F.2d at 1220
    (footnote omitted).
    Lands served by the Project are divided into the “Truckee
    Division” and the “Carson Division.” United States v. Alpine
    Land & Reservoir Co., 
    887 F.2d 207
    , 208 (9th Cir. 1989)
    (Alpine III). At the Derby Diversion Dam east of Sparks,
    Nevada, part of the Truckee River’s flow is diverted from its
    natural course to Pyramid Lake. 
    Id.
     A portion of that
    diverted water supplies irrigators in the Truckee Division; the
    remainder is impounded in the Lahontan Reservoir and
    released into the Carson River to supply irrigators in the
    Carson Division. 
    Id.
     “Because diversions from the Carson
    River do not directly affect Pyramid Lake, the Tribe has
    sought and obtained judicial rulings that Carson River flows
    should be utilized whenever possible, before Truckee River
    flows, to supply the Project with its necessary water.” 
    Id.
     at
    210 n.2 (citing Pyramid Lake Paiute Tribe of Indians v.
    Morton, 
    354 F. Supp. 252
     (D. D.C. 1973)). Thus, we have
    acknowledged that decreasing water demand in the Carson
    Division correspondingly decreases the quantity of Truckee
    River water used there, which in turn increases flows to
    Pyramid Lake. 
    Id.
    Two federal court decrees—products of suits by the
    United States to quiet title to Truckee and Carson River
    water—govern water rights in the Newlands Project. The Orr
    Ditch Decree, In Equity Dkt. No. A3, slip op. (D. Nev. Sept.
    PYRAMID LAKE PAIUTE TRIBE V. NEVADA                            9
    8, 1944), allocates water rights on the Truckee River,2 while
    the Alpine Decree, Civil No. D-183, slip op. (D. Nev. Oct. 28,
    1980), governs the Carson River water rights at issue in this
    appeal.3 The Alpine Decree establishes “water duties” for
    different categories of irrigable lands within the Project,
    which articulate the maximum quantity of Project water that
    a landowner may apply to a particular parcel. The water duty
    for the Project bottom lands at issue in this appeal is 3.5 acre-
    feet per acre (“afa”), while the duty for higher-elevation
    “bench lands” is 4.5 afa. United States v. Alpine Land &
    Reservoir Co., 
    503 F. Supp. 877
    , 888 (D. Nev. 1980). These
    figures are based on the quantity of water needed to grow
    alfalfa, the dominant crop in the Newlands Project. 
    Id.
    Because some water is inevitably lost to evaporation or
    during transport, the water duties are set somewhat higher
    than the quantity of water actually taken up by the alfalfa
    plants. Specifically, the 3.5 afa water duty at issue in this
    case includes a “consumptive use” portion of 2.99
    afa—which accounts for the quantity of water actually
    consumed by crop growth—plus a “non-consumptive use”
    portion of 0.51 afa. 
    Id.
    2
    Under the Orr Ditch Decree, the Pyramid Lake Paiute Tribe has the
    right to divert 58.7 second feet and 12,412 acre feet of water per year from
    the Truckee River to irrigate Reservation lands. Nevada, 
    463 U.S. at
    117–18. The United States has the right to divert 1,500 cubic feet per
    second to irrigate land within the Newlands Project. 
    Id.
    3
    The Alpine Decree allocates the full flow of the Carson River above
    Lahontan Dam to the United States for distribution to landowners in the
    Newlands Project. See United States v. Alpine Land & Reservoir Co.,
    
    503 F. Supp. 877
     (D. Nev. 1980). The Tribe has no decreed water rights
    in the Carson River.
    10         PYRAMID LAKE PAIUTE TRIBE V. NEVADA
    The Alpine Decree also establishes rules for transferring
    decreed water rights to new locations and uses within the
    Project. Alpine V, 
    291 F.3d at
    1066–67. Of significance to
    this appeal, Administrative Provision VII of the Decree states
    that a party may only transfer the consumptive use portion of
    its water right to a use other than irrigation.4 See Alpine
    Land & Reservoir Co., 
    503 F. Supp. at 893
    . Thus, a
    landowner in the Project’s bottom lands who applies to
    change the manner of use for an irrigation water right can
    only apply 2.99 afa to the new use; the 0.51 afa non-
    consumptive use portion must stay in the river. This
    limitation is designed to protect the efficiency benefits of the
    “return-flow” method of irrigation practiced in the Newlands
    Project. 
    Id.
     Under this method, water is diverted into
    centralized ditches or canals, applied to the land of the most
    senior appropriator,5 and then allowed to run or seep onto
    adjacent parcels or into another diversion canal. 
    Id.
     at
    891–92. The Alpine Decree court found this method more
    efficient than irrigation by direct diversions to each
    landowner via individual irrigation ditches. 
    Id. at 892
    . It also
    found that allowing holders of irrigation water rights to
    change the manner of use to a non-irrigation purpose would
    4
    Administrative Provision VII states, in relevant part, that “[c]hange in
    manner of use applications from use for irrigation to any other use
    . . . shall be allowed only for the net consumptive use of the water as
    determined by this Decree.” Alpine Decree, Civil No. D-183, slip op. at
    161–62.
    5
    Under the Western water law maxim of “first in time, first in right,”
    landowners who secure water rights earlier in time—so-called “senior”
    rights-holders—are entitled to take their share of water in times of scarcity
    before those with later-secured “junior” rights. E.g., Charles F.
    Wilkinson, Western Water Law in Transition, 
    56 U. Colo. L. Rev. 317
    ,
    319–20 (1985).
    PYRAMID LAKE PAIUTE TRIBE V. NEVADA                   11
    undermine the efficacy of the return-flow method by
    transferring the 0.51 afa non-consumptive use portion of
    those rights—which previously reached downstream users as
    return flows—to a consumptive use. Id. at 893. To address
    this issue, Administrative Provision VII’s prohibition on
    transferring the non-consumptive use portion of irrigation
    rights to other uses ensures that “[w]ater that has been
    allowed in the duties for purposes of irrigation coverage
    could not then be changed to a consumptive use and
    disappear from the return flows to other water right lands or
    the river.” Id.
    Under the Alpine Decree, the Nevada State Engineer
    adjudicates applications to change the manner of use, place of
    use, or place of diversion for decreed water rights according
    to Nevada law. Id. However, the U.S. District Court for the
    District of Nevada, which issued the Alpine Decree, retains
    jurisdiction over challenges to the State Engineer’s decisions
    on change applications. Id.; 
    Nev. Rev. Stat. § 533.450
    (1).
    II
    This appeal concerns applications filed by the Nevada
    Department of Wildlife (“the Department”) and the Nevada
    Waterfowl Association (“the Association”) to transfer water
    rights from agricultural land in the Newlands Project to the
    Carson Lake and Pasture, a wildlife refuge located within the
    Lahontan Valley wetlands at the terminus of the Carson
    River.6 Like Pyramid Lake, the Lahontan Valley wetlands
    have suffered from the systematic diversion of water to
    6
    The Department manages the wildlife refuge at Carson Lake and
    Pasture under an agreement with the United States Department of the
    Interior.
    12        PYRAMID LAKE PAIUTE TRIBE V. NEVADA
    landowners in the Newlands Project. See United States v.
    Alpine Land & Reservoir Co., 
    341 F.3d 1172
    , 1176 (9th Cir.
    2003) (Alpine VII) (describing impacts).
    Historically, the Carson River supported an average of
    150,000 acres of wetlands, which provided important habitat
    for waterfowl, shorebirds, and other wildlife. “The Project,
    however, altered the natural hydrological flow in the
    wetlands, as flooding that had previously sent springtime
    flows down the Carson River into the marshes was contained
    and diverted into Project irrigation canals for delivery to
    newly created farmlands in the Carson Division of the
    Project.” 
    Id.
     As a result, “the Lahontan Valley wetlands and
    marshes largely dried up.” 
    Id.
     (citing Churchill Cnty. v.
    Norton, 
    276 F.3d 1060
    , 1068 (9th Cir. 2001)). To stave off
    further habitat loss, Congress authorized the Secretary of the
    Interior and Nevada conservation agencies to acquire and
    transfer water rights from willing landowners in the
    Newlands Project to the wetlands. See 
    id.
     at 1176–77.
    At issue are three applications submitted by the
    Department and the Association (collectively, the
    “Applicants”) to the State Engineer to transfer water rights
    from agricultural lands in the Carson Division to Carson Lake
    and Pasture to sustain wildlife habitat. The Applicants
    contend that they seek only to change the water’s place of
    use, but not its manner of use. Because they propose to use
    the transferred water to support the growth of plants used by
    wildlife,7 they argue that the intended use of water at Carson
    Lake and Pasture constitutes irrigation. Relying on this
    7
    The plants the Applicants wish to cultivate at Carson Lake and Pasture
    include Sago pond weed, widgeon grass, alkalai bulrush, saltgrass, hard
    stem bulrush, red goosefoot, smart weeds, and water grass millets.
    PYRAMID LAKE PAIUTE TRIBE V. NEVADA                            13
    theory, the Applicants sought to transfer both the
    consumptive and non-consumptive use portions of the water
    rights at issue.8
    The Tribe and the United States protested the applications
    before the State Engineer,9 claiming that the applications
    violate Administrative Provision VII of the Alpine Decree
    because they seek to transfer the non-consumptive use portion
    of agricultural irrigation rights to a non-irrigation use,
    namely, use for “recreation, wildlife and/or the maintenance
    and preservation of wetlands.” The State Engineer rejected
    this argument, finding that the Applicants’ proposed use of
    water at Carson Lake and Pasture “can be described as
    irrigation” because it involves “the provision of water for
    plant growth.” Because he found that the applications do not
    seek to change the manner of use from irrigation to another
    category, the State Engineer approved the applications to
    transfer the full water duty for the rights at issue.
    The Tribe and the United States sought review of the
    State Engineer’s decision in the U.S. District Court for the
    District of Nevada, invoking its reserved jurisdiction under
    the Alpine Decree. See United States v. Alpine Land &
    8
    The Association filed applications 71775 and 73574, which both seek
    to transfer the full 3.5 afa water duty from agricultural use on private lands
    within the Project to Carson Lake and Pasture. In application 73444, The
    Department seeks to transfer only the 0.51 afa non-consumptive use
    portion of the rights at issue because the non-consumptive use portion was
    transferred under an earlier application.
    9
    Due to administrative oversight, the United States joined the Tribe in
    protesting only one of the three transfer applications at issue. However,
    since all three applications raise the same legal issue, that fact is not
    material to this appeal.
    14        PYRAMID LAKE PAIUTE TRIBE V. NEVADA
    Reservoir Co./Churchill Cnty. v. Turnipseed, 
    174 F.3d 1007
    ,
    1011 (9th Cir. 1999) (affirming that, in the Alpine Decree, the
    district court reserved jurisdiction to review adjudications of
    transfer applications for decreed water rights). The district
    court held that the Applicants’ proposed use of water at
    Carson Lake and Pasture is not “irrigation” within the
    meaning of the Alpine Decree. United States v. Alpine Land
    & Reservoir Co., 
    788 F. Supp. 2d 1209
    , 1219 (D. Nev. 2011).
    It explained that,
    [t]aken as a whole, the Alpine Decree’s
    references to irrigation establish that the only
    irrigation use contemplated by the Decree was
    for agriculture, whether for productively
    growing valuable cash crops or for pasture
    lands. While the word “irrigation” can be
    defined as any application of a liquid, the
    Alpine Decree considered and referred to
    irrigation use in the context of agriculture, and
    specifically to grow cash crops and pasture.
    The decree court itself recognized that one of
    its central tasks was to establish a water duty
    to irrigate farmlands.
    
    Id. at 1217
     (footnote omitted). The district court also
    observed that Nevada law, which the Alpine Decree
    incorporates as the source of substantive water law, defines
    “wildlife purposes” as a distinct use of water. 
    Id.
     at 1218
    (citing 
    Nev. Rev. Stat. § 533.023
    ).10 It concluded that the
    10
    That provision defines “wildlife purposes” to “include[] the watering
    of wildlife and the establishment and maintenance of wetlands, fisheries
    and other wildlife habitats.” 
    Nev. Rev. Stat. § 533.023
    . There is no
    statutory definition of “irrigation” under Nevada law.
    PYRAMID LAKE PAIUTE TRIBE V. NEVADA                  15
    Applicants’ proposed use of water falls within the state law
    definition of “wildlife purposes,” which further evidences that
    it is not “irrigation.” 
    Id.
     Thus, the district court reversed the
    decision of the State Engineer and vacated his approval of the
    transfer applications. Id. at 1219.
    This timely appeal followed.
    III
    At the outset, the Association argues that the Tribe lacks
    standing under Article III and the Alpine Decree because it
    does not allege injury to its decreed water rights. The
    Association is correct that the Tribe lacks water rights under
    the Alpine Decree, and its rights to Truckee River water under
    the Orr Ditch Decree are not threatened by the State
    Engineer’s decision in this case. However, the Tribe satisfies
    the constitutional standing requirement by plausibly alleging
    that the Applicants’ proposed transfer of water rights to
    Carson Lake and Pasture will increase demand for Truckee
    River water in the Carson Division and thereby diminish
    flows to Pyramid Lake. Moreover, the Tribe properly
    invoked the district court’s reserved jurisdiction to review
    adjudications of water rights under the Alpine Decree.
    It is well established that “the irreducible constitutional
    minimum of standing contains three elements”: (1) a concrete
    and particularized injury that is “actual or imminent, not
    conjectural or hypothetical”; (2) a causal connection between
    the injury and the defendant’s challenged conduct; and (3) a
    likelihood that a favorable decision will redress that injury.

    first of these elements is at issue, and the Tribe’s allegation
    16         PYRAMID LAKE PAIUTE TRIBE V. NEVADA
    that the State Engineer’s decision will increase demand for
    Truckee River water in the Carson Division and thereby
    reduce flows to Pyramid Lake establishes a cognizable injury.
    The Association does not dispute the Alpine Decree court’s
    finding that reducing return flows in the Carson Division
    diminishes irrigation efficiency, Alpine Land & Reservoir
    Co., 
    503 F. Supp. at 892
    , which prompts increased diversions
    from the Truckee River and reduces flows to Pyramid Lake,
    Alpine III, 
    887 F.2d at
    210 n.2. And the Tribe’s interest in
    maximizing flows to Pyramid Lake—which lies entirely
    within the boundaries of the Tribe’s reservation and is central
    to its cultural and economic life—is well established. See,
    e.g., Alpine III, 
    887 F.2d at 208
     (recognizing that, “[b]ecause
    any water diverted from the Truckee cannot be recovered for
    use at the Tribe’s fishery at Pyramid Lake, the Tribe is vitally
    interested in limiting the diversion of Truckee River water”).
    That the individual permitting decisions at issue in this case
    may have a de minimis impact on flows to Pyramid Lake
    does not defeat the Tribe’s standing. See 
    id. at 214
    (recognizing the Tribe’s standing to challenge individual
    adjudications by the State Engineer that cumulatively affect
    the Tribe’s interests in the Truckee River and Pyramid
    Lake).11
    11
    Refusing to recognize the Tribe’s standing because of the de minimis
    impact of individual permit decisions would, as a practical matter, leave
    the Tribe without recourse to protect its interest in maximizing flows to
    Pyramid Lake. As we explained in Alpine III, individual adjudications
    that incrementally increase diversions from the Truckee River can effect
    a death by a thousand cuts for Pyramid Lake. See Alpine III, 
    887 F.2d at 214
     (recognizing that “the total effect on the Tribe’s water rights is
    ultimately the sum of the individual parts”). Moreover, the Applicants
    admit that this is a test case and, if successful, they intend to transfer
    thousands of acre-feet of additional water under the same theory. The
    only way the Tribe can challenge the potential loss of thousands of acre-
    PYRAMID LAKE PAIUTE TRIBE V. NEVADA                          17
    In addition, the Tribe properly invoked the district court’s
    reserved jurisdiction to review the State Engineer’s
    adjudication of decreed water rights. In Orr Ditch IV, we
    held that the district court lacks jurisdiction to review the
    State Engineer’s adjudication of non-decreed water rights
    unless the plaintiff alleges injury to its decreed water rights.
    Orr Ditch IV, 600 F.3d at 1160. Since the district court’s
    reserved jurisdiction over the State Engineer’s decisions is
    “an adjunct to its jurisdiction over the quiet title action” that
    spawned the Decree, Alpine II, 
    878 F.2d at
    1219 n.2, that
    jurisdiction is necessarily limited to review of the Engineer’s
    decisions that affect rights granted under the Decree. Here,
    however, the plaintiffs need not allege injury to their decreed
    water rights because the challenged transfer applications
    concern decreed water rights.             Having cleared the
    constitutional standing hurdle, the Tribe is free to invoke the
    district court’s undisputed jurisdiction to review decisions of
    the State Engineer that concern decreed water rights.12
    IV
    The sole issue on the merits is whether the Applicants’
    proposed use of water at Carson Lake and Pasture constitutes
    “irrigation” within the meaning of the Alpine Decree. We
    review the district court’s interpretation of the Alpine Decree
    de novo. United States v. Orr Water Ditch Co., 914 F.2d
    feet of water that would otherwise reach Pyramid Lake is to challenge the
    State Engineer’s approval of individual transfer applications.
    12
    Even if the Association were correct that the Tribe cannot invoke the
    district court’s Alpine Decree jurisdiction in this case, jurisdiction would
    be proper under 
    28 U.S.C. § 1345
    , which vests district courts with original
    jurisdiction in all civil actions commenced by the United States.
    18       PYRAMID LAKE PAIUTE TRIBE V. NEVADA
    1302, 1307 (9th Cir. 1990) (Orr Ditch I). Whether we rely on
    the language and history of the Alpine Decree itself or the
    provisions of Nevada law incorporated therein, we agree with
    the district court that the proposed use of water is not
    irrigation.
    Though it does not define “irrigation,” the Alpine Decree
    expresses a singular concern with the provision of irrigation
    water for agricultural use, and its references to irrigation
    uniformly relate to agriculture. For instance, the Decree’s
    first administrative provision states that the lands in the
    Newlands Project “are dry and arid and irrigation is necessary
    for the production of valuable crops thereon.” Alpine
    Decree, Civ. No. D-183, slip op. at 157 (emphasis added).
    Consistent with this finding, decreed water rights are based
    on the quantity of water “necessary and sufficient for the
    reasonable and economical irrigation of crops thereon.” 
    Id.
    In its accompanying opinion, the district court stated that one
    of its “central tasks” in fashioning the Alpine Decree was to
    “establish a clear and specific water duty for both the
    Newlands Project farmlands and the upper Carson
    farmlands.” Alpine Land & Reservoir, 
    503 F. Supp. at 887
    .
    The Applicants fail to identify any language in the Decree or
    accompanying opinion suggesting that the Decree’s
    references to irrigation encompass anything more than the
    application of water to cultivate crops for human or livestock
    consumption.
    Based on this language, we have similarly described the
    purpose of the Newlands Project and the governing decrees
    as facilitating agricultural irrigation. See, e.g., Alpine VI,
    340 F.3d at 907 (stating that “[t]he Project was intended to
    convert some of the country’s most arid land into irrigated
    farmland . . . .”); Alpine V, 
    291 F.3d at 1066
     (stating that
    PYRAMID LAKE PAIUTE TRIBE V. NEVADA                          19
    “[t]he Project was designed to irrigate a substantial area . . .
    in order to facilitate its conversion to farmland”) (emphasis
    added); Alpine II, 
    878 F.2d at 1220
     (citations and footnote
    omitted) (describing the Project’s purpose as “turning
    wasteland into farmland” by “irrigat[ing] a substantial
    amount of [the Project] land with water from the Truckee and
    Carson Rivers . . . .”); United States v. Alpine Land &
    Reservoir Co., 
    697 F.2d 851
    , 860 (9th Cir. 1983) (Alpine I)
    (stating that the Project’s Lahontan reservoir, “as a project
    built under the federal Reclamation Act, was intended for the
    primary benefit of the farmers who would use its waters for
    irrigation . . . . .”). We find no contrary evidence that would
    support our departure from this longstanding interpretation.13
    13
    Though not addressing the Newlands Project specifically, decisions
    of the Nevada Supreme Court and the United States Supreme Court
    likewise equate “irrigation” with agricultural use. See, e.g., United States
    v. California, 
    438 U.S. 645
    , 648–49 (1978) (describing the origins of
    modern irrigation in Mormon pioneers’ cultivation of potatoes); 
    id. at 651
    (distinguishing the use of water for “irrigation” from use for “the
    protection of fish and wildlife”); Prosole v. Steamboat Canal Co., 
    140 P. 720
    , 722–23 (Nev. 1914) (equating an “irrigation” right with “a water
    right for agricultural purposes” and describing the purpose of water law
    as facilitating “the actual economic application of the exceedingly scarce,
    but all-important element, water to the soil, with the end in view that the
    latter may perform its highest function in producing sustenance for
    humanity”) (emphasis added). Similarly, water law scholars consistently
    equate irrigation with agriculture and distinguish irrigation from the use
    of water for wildlife, recreation, or aesthetic purposes. See, e.g., A. Dan
    Tarlock, The Future of Prior Appropriation in the West, 41 Nat. Res. J.
    769, 770, 772 (2001) (describing the goal of federal reclamation as
    “settl[ing] the West with irrigated family farms,” and distinguishing
    agricultural irrigation rights, which are the “core” concern of Western
    water law, from contemporary uses of water for urban and environmental
    purposes).
    20         PYRAMID LAKE PAIUTE TRIBE V. NEVADA
    Moreover, the undisputed facts indicate that the
    Applicants’ proposed use of water at Carson Lake and
    Pasture constitutes a “wildlife” use under Nevada law, which
    is a distinct use from irrigation. See State v. Morros,
    
    766 P.2d 263
    , 268 (Nev. 1988) (stating that wildlife watering
    is encompassed within the state law definition of recreation
    as a beneficial use of water). Nevada law governs “both the
    process and the substance of a proposed transfer of water
    rights” under the Alpine Decree, Alpine II, 
    878 F.2d at 1223
    ,
    and defines the “beneficial uses” to which Project water may
    be put, Alpine I, 
    697 F.2d at 854
    . Thus, we look to the
    Nevada water code to determine whether the Applicants in
    fact propose to change the manner of use for their transferred
    water rights from “irrigation” to “wildlife” use.14
    The Nevada water code defines “wildlife purposes” to
    “include the watering of wildlife and the establishment and
    maintenance of wetlands, fisheries, and other wildlife
    habitats.” 
    Nev. Rev. Stat. § 533.023.15
     On its face, this
    14
    Though Nevada law is the source of substantive water law governing
    rights under the Alpine Decree, we need not consider, let alone defer to,
    the opinions of the Department and the State Engineer that the proposed
    use of water at Carson Lake and Pasture qualifies as irrigation. At bottom,
    this appeal requires us to determine the meaning of “irrigation” in
    Administrative Provision VII of the Alpine Decree, a question we review
    de novo according to the language, structure, and purpose of the Decree
    and the substantive state law provisions incorporated therein.
    15
    That the Nevada legislature codified this definition nine years after
    entry of the Alpine Decree is of no moment. “It is settled that beneficial
    use expresses a dynamic concept, which is a variable according to
    conditions, and therefore over time.” Alpine I, 
    697 F.2d at 855
     (internal
    quotation marks and citations omitted). Thus, we acknowledge
    developments in state law when defining and distinguishing between
    beneficial uses of water in the Newlands Project. It is also immaterial that
    PYRAMID LAKE PAIUTE TRIBE V. NEVADA                        21
    definition encompasses the Applicants’ proposed use of water
    to maintain wildlife habitat at Carson Lake and Pasture.
    Moreover, the code distinguishes between “wildlife
    purposes” and other beneficial water uses such as agricultural
    irrigation. See 
    Nev. Rev. Stat. §§ 533.135
     (establishing $60
    fee for proof of water right for livestock or wildlife purposes
    and $120 fee for proof of water rights for all other purposes),
    533.0243(1) (declaring state policy of allowing the temporary
    transfer of agricultural water rights to wildlife and other
    instream uses). Thus, the Applicants’ contention that their
    proposed use of water qualifies as both “wildlife” and
    “irrigation” lacks merit.
    In an abstract sense, the Applicants’ argument has
    technical support insofar as their proposed use of water at
    Carson Lake and Pasture, like the cultivation of alfalfa or
    livestock pasture, involves the mechanical application of
    water to grow plants. And the Applicants and State Engineer
    cite dictionaries, irrigation textbooks, and state agency
    publications that expansively define “irrigation” so as to
    encompass their proposed use. But in the context of the
    Alpine Decree and the Nevada water code, the argument
    plainly fails. Both the Decree and the state water code speak
    of irrigation solely in the context of agriculture and
    distinguish such use from the application of water for
    recreational, aesthetic, and wildlife purposes. There is simply
    no indication that either of the two relevant sources embraces
    the application of water to sustain wildlife habitat in its
    the Nevada legislature declined to amend the statutory provision
    enumerating beneficial uses of water to explicitly include “wildlife
    purposes” as a distinct use. Because the Morros court determined that
    wildlife use is a component of recreation, which is statutorily defined as
    a beneficial use, such amendment was unnecessary.
    22       PYRAMID LAKE PAIUTE TRIBE V. NEVADA
    definition of “irrigation.” Therefore, we agree with the
    district court that the State Engineer’s approval of the
    applications to transfer the non-consumptive use portion of
    the Applicants’ water rights violated Administrative
    Provision VII of the Alpine Decree because the applications
    seek a change in the manner of use to a non-irrigation
    purpose. While we recognize the salutary purpose to which
    the Applicants wish to apply water at Carson Lake and
    Pasture, they may not do so in contravention of the express
    limitation on transfers of water rights articulated in the Alpine
    Decree.
    V
    In sum, the district court correctly concluded that
    diversion of water for waterfowl habitat is not “irrigation”
    within the meaning of the Alpine decree. We affirm the
    judgment of the district court.
    AFFIRMED.
