    Opinion by Judge Collins
    SUMMARY *
    Environmental Law
    The panel affirmed the district court’s summary
    judgment order, in which the district court rejected plaintiff
    environmental groups’ challenges to the government’s
    allowance of livestock grazing in three areas of the
    Stanislaus National Forest in California.
    In 1981, the California State Water Resources Control
    Board signed a Management Agency Agreement (“MAA”)
    with the U.S. Forest Service to formally recognize it as the
    management agency on Forest Service lands to implement
    water management plans.
    *
    This summary constitutes no part of the opinion of the court. It
    has been prepared by court staff for the convenience of the reader.
    CSERC V. STANISLAUS NAT’L FOREST                   3
    The U.S. Forest Service issued grazing permits in three
    allotments at issue here – the Bell Meadow, Eagle Meadow,
    and Herring Creek Allotments (the “BEH Allotments”).
    Plaintiffs alleged that the Forest Service’s allowance of
    livestock grazing in the BEH Allotments led to fecal matter
    runoff that polluted streams in the area, and this impaired
    their members’ ability to recreate in the relevant areas of the
    Stanislaus National Forest. The BEH Allotments fall under
    the jurisdiction of the Central Valley Regional Water Quality
    Control Board, whose Basin Plan defines the beneficial uses
    for the subject waterways and the water quality objectives
    that would protect those beneficial uses. The only claim at
    issue in this appeal alleged that the government violated
    § 313 of the Clean Water Act by failing to comply with
    several requirements of California’s Porter-Cologne Water
    Quality Control Act.
    The panel held that the plaintiffs had Article III standing
    under the associational standing doctrine. At least one
    member of each plaintiff organization averred that they
    regularly hike in all three Allotments and that the physical
    impacts of the cattle grazing impair their present and
    anticipated enjoyment of the area, including its creeks and
    streams. This showing was sufficient to establish an Article
    III injury-in-fact.
    In alleging a violation of § 313 of the Clean Water Act,
    plaintiffs first contended that the government violated
    California’s Porter-Cologne Act by failing to file a discharge
    report and by discharging waste without first obtaining either
    water discharge requirements (“WDR”s) or a waiver. The
    panel held that the MAA clearly established that, in lieu of
    filing reports and obtaining WDRs, the Forest Service would
    instead implement the agreed-upon Best Management
    Practices (“BMP”s) and the provisions of the MAA.
    4          CSERC V. STANISLAUS NAT’L FOREST
    Second, plaintiffs asserted that the MAA was superseded by
    the State Board’s adoption of the 2004 “Policy for
    Implementation and Enforcement of the Nonpoint Source
    Pollution Control Program” (“2004 NPS Policy”). The
    panel held that this argument was refuted by the text of that
    document. That the Forest Service is working with the
    regional board on options for replacing the MAA did not
    establish that the MAA has already been replaced.
    Accordingly, the panel concluded that plaintiffs failed to
    show that government violated the reporting and permitting
    requirements of 
    Cal. Water Code §§ 13260
    , 13263, and
    13264. The panel affirmed the district court’s summary
    judgment on these issues.
    Plaintiffs also alleged that the government violated § 313
    of the Clean Water Act by authorizing livestock grazing that
    caused runoff that led to fecal coliform levels in local
    waterways in excess of the relevant water quality objectives
    in the Central Valley Regional Board’s Basin Plan. The
    panel held that the argument failed because the Basin Plan
    objectives did not apply directly, of their own force, to
    individual dischargers but instead reflected standards that
    regulators must take into account in fashioning the
    requirements that do apply to dischargers (such as WDRs,
    waivers, and basin-plan prohibitions). The panel affirmed
    the district court’s summary judgment to defendants with
    respect to plaintiffs’ claims based on asserted violations of
    the basis plan’s water quality objectives.

    OPINION
    COLLINS, Circuit Judge:
    Plaintiffs Central Sierra Environmental Resource Center
    (“CSERC”) and Sierra Forest Legacy (“SFL”) appeal the
    district court’s summary judgment order rejecting their
    challenges to the Government’s allowance of livestock
    grazing in three areas of the Stanislaus National Forest.
    Plaintiffs contend that, in allowing such grazing, the
    Government has violated multiple provisions of state water
    quality laws made applicable to the Government under the
    Clean Water Act. We affirm.
    6           CSERC V. STANISLAUS NAT’L FOREST
    I
    Before turning to the specific factual background of this
    case, we begin with an overview of the relevant water quality
    laws that frame the parties’ dispute.
    A
    As rewritten in 1972, the Federal Water Pollution
    Control Act, popularly known as the “Clean Water Act” (the
    “Act”), 
    33 U.S.C. § 1251
     et seq., aimed to “restore and
    maintain the chemical, physical, and biological integrity of
    the Nation’s waters.” 
    33 U.S.C. § 1251
    (a); see also PUD
    No. 1 of Jefferson Cnty. v. Washington Dep’t. of Ecology,
    
    511 U.S. 700
    , 704 (1994). “To achieve these ambitious
    goals, the Clean Water Act establishes distinct roles for the
    Federal and State Governments.” PUD No. 1, 
    511 U.S. at 704
    . In particular, “the Administrator of the Environmental
    Protection Agency (EPA) is required . . . to establish and
    enforce technology-based limitations on individual
    discharges into the country’s navigable waters from point
    sources.” 
    Id.
     (emphasis added) (citing 
    33 U.S.C. §§ 1311
    ,
    1314). Section 502 of the Act defines a “point source” to
    mean “any discernible, confined and discrete conveyance
    . . . from which pollutants are or may be discharged,” such
    as a “pipe” or a “ditch.” 
    33 U.S.C. § 1362
    (14). As we have
    previously held, however, “runoff from . . . animal
    grazing”—which is the form of pollution at issue here—does
    not fit this definition and is therefore considered to be a
    “nonpoint source[].” Oregon Nat. Desert Ass’n v. Dombeck,
    
    172 F.3d 1092
    , 1095 (9th Cir. 1998) (emphasis added). 1 The
    1
    We therefore have no occasion in this case to address or apply any
    provisions of federal or state law specifically addressing regulation of
    pollution from point sources.
    CSERC V. STANISLAUS NAT’L FOREST                  7
    Clean Water Act “provides no direct mechanism to control
    nonpoint source pollution” and instead “uses the ‘threat and
    promise’ of federal grants” to incentivize the States to do so.
    
    Id. at 1097
    .
    Specifically, to “encourag[e] and facilitat[e] the
    development and implementation of areawide waste
    treatment management plans,” § 208 of the Act requires the
    States to designate, for specified geographic areas, “an
    organization capable of developing effective areawide waste
    treatment management plans for such area.” 
    33 U.S.C. § 1288
    (a), (a)(2). Such plans are more commonly known as
    “[w]ater quality management (WQM) plan[s],” see
    
    40 C.F.R. § 130.2
    (k), and they must contain a variety of
    elements, including “procedures and methods” to control
    “agriculturally and silviculturally related nonpoint sources
    of pollution, including . . . runoff from manure disposal
    areas, and from land used for livestock and crop production.”
    
    33 U.S.C. § 1288
    (b)(2)(F). Section 208(c) also requires
    States to designate “one or more” agencies for each
    geographic area to carry out the relevant WQM plans. 
    Id.
    § 1288(c)(1). In addition to WQM plans under § 208, the
    Clean Water Act requires States, under § 319, “to adopt
    nonpoint source management programs,” and it “similarly
    provides for grants to encourage a reduction in nonpoint
    source pollution.” Dombeck, 172 F.3d at 1097 (citing
    
    33 U.S.C. § 1329
    ).
    Notably, § 313(a) of the Act requires any federal
    “department, agency, or instrumentality” that has
    “jurisdiction over any property or facility” or that “engage[s]
    in any activity resulting, or which may result, in the
    discharge or runoff of pollutants” to “comply with[] all
    Federal, State, interstate, and local requirements . . .
    respecting the control and abatement of water pollution in
    8         CSERC V. STANISLAUS NAT’L FOREST
    the same manner, and to the same extent as[,] any
    nongovernmental entity.”            
    33 U.S.C. § 1323
    (a).
    Accordingly, federal agencies managing federal lands
    generally must comply with the water pollution laws and
    regulations of the relevant State, including the State’s laws
    concerning discharges from nonpoint sources.
    The Porter-Cologne Water Quality Control Act (“Porter-
    Cologne Act”), see CAL. WATER CODE § 13000 et seq., is
    “the principal law governing water quality regulation in
    California.” Monterey Coastkeeper v. Central Coast Reg’l
    Water Quality Control Bd., ___ Cal. Rptr. 3d ___, 
    2022 WL 669903
    , at *1 (Ct. App. Feb. 10, 2022). It established the
    State Water Resources Control Board (“State Board”) along
    with nine regional water quality control boards (“regional
    boards”). See CAL. WATER CODE §§ 13100, 13200, 13201;
    see also id. § 175. These ten agencies have “primary
    responsibility for the coordination and control of water
    quality” in California. Id. § 13001.
    The State Board formulates and adopts statewide water
    quality control policies that are binding on the regional
    boards. See CAL. WATER CODE §§ 13140, 13141, 13146,
    13240. The State Board also “may adopt water quality
    control plans” for “waters for which water quality standards
    are required by” the Clean Water Act. Id. § 13170. Any
    such water quality control plans adopted by the State Board
    “supersede any regional water quality control plans for the
    same waters to the extent of any conflict.” Id.
    Subject to the approval of the State Board, each regional
    board must “formulate and adopt water quality control
    plans” for its respective region, id. § 13240; see also id.
    § 13245, which are commonly known as “basin plans,”
    Monterey Coastkeeper, 
    2022 WL 669903
    , at *1. These
    basin plans must specify, “for the waters within a specified
    CSERC V. STANISLAUS NAT’L FOREST                 9
    area,” each of the following: (1) the “[b]eneficial uses to be
    protected”; (2) the applicable “[w]ater quality objectives,”
    i.e., “the limits or levels of water quality constituents or
    characteristics which are established for the reasonable
    protection of beneficial uses of water or the prevention of
    nuisance within a specific area”; and (3) a “program of
    implementation needed for achieving” those objectives.
    CAL. WATER CODE § 13050(h), (j)(1)–(3). In establishing
    “water quality objectives,” the regional board must consider
    several nonexhaustive statutory factors, including the
    relevant “[e]nvironmental characteristics,” the “[w]ater
    quality conditions that could reasonably be achieved through
    the coordinated control of all factors which affect water
    quality in the area,” and general “[e]conomic
    considerations.” Id. § 13241. In formulating a program of
    implementation, the regional board must provide a
    “description of the nature of [the] actions which are
    necessary to achieve the objectives,” a “time schedule” for
    such actions, and a “description” of the “surveillance to be
    undertaken to determine compliance with objectives.” Id.
    § 13242. In addition to these programmatic elements, a
    basin plan may contain specific prohibitions, i.e., it “may
    specify certain conditions or areas where the discharge of
    waste, or certain types of waste, will not be permitted.” Id.
    § 13243.
    In addition to developing overall basin plans, the
    regional boards are responsible for regulating the specific
    actions of relevant dischargers through “permitting,
    inspection, and enforcement actions.”            Monterey
    Coastkeeper, 
    2022 WL 669903
    , at *1. Among the primary
    mechanisms regional boards use to regulate discharges are
    (1) the receipt of statutorily required reports concerning
    discharges and (2) the issuance of discharge permits. See
    10          CSERC V. STANISLAUS NAT’L FOREST
    Department of Finance v. Commission on State Mandates,
    
    378 P.3d 356
    , 361–62 (Cal. 2016).
    Specifically, unless the reporting requirement has been
    waived under § 13269, the Porter-Cologne Act requires each
    “person discharging waste, or proposing to discharge waste,
    within any region that could affect the quality of the waters
    of the state” to file with the appropriate regional board a
    “report of the discharge, containing the information that may
    be required by the regional board.” See CAL. WATER CODE
    § 13260(a)(1). After receiving the report, “[t]he regional
    board then ‘shall prescribe requirements as to the nature’ of
    the discharge.” Department of Finance, 378 P.3d at 361
    (quoting CAL. WATER CODE § 13263(a)). Such “waste
    discharge requirements” (“WDRs”) are “the equivalent of
    the term ‘permits’ as used” in the Clean Water Act, see CAL.
    WATER CODE § 13374, and they authorize the relevant
    person to make the specified discharges in accordance with
    those requirements. See id. §§ 13263(f), 13264, 13265. In
    formulating such WDRs for specific discharges, the regional
    board “shall implement” any relevant basin plan, and “shall
    take into consideration,” inter alia, “the beneficial uses to be
    protected, the water quality objectives reasonably required
    for that purpose, other waste discharges, [and] the need to
    prevent nuisance.” Id. § 13263(a). 2
    Alternatively, the regional board may issue a waiver of
    the need for WDRs for a “specific discharge or type of
    discharge.” Id. § 13269(a)(1). The waiver must set forth
    2
    The State Board also has the authority to issue WDRs under
    § 13263. See CAL. WATER CODE § 13263(j). Moreover, under specified
    circumstances, either the State Board or a regional board may “prescribe
    general waste discharge requirements for a category of discharges.” Id.
    § 13263(i) (emphasis added).
    CSERC V. STANISLAUS NAT’L FOREST                 11
    certain conditions, and it must generally provide for
    appropriate monitoring and reporting of the covered
    discharges. Id. § 13269(a)(2). As a general matter, in the
    absence of WDRs under § 13263 or a waiver under § 13269,
    no person “shall initiate any new discharge of waste or make
    any material changes in any discharge.” Id. § 13264(a).
    Because an applicable waiver under § 13269 authorizes the
    relevant discharges, see id. § 13264(a)(3), it is in that sense
    also functionally equivalent to a permit.
    B
    In 1981, the State Board signed a Management Agency
    Agreement (“MAA”) with the United States Forest Service
    (“Forest Service”). The MAA formally recognized the
    State’s designation of the Forest Service, pursuant to
    § 208(c) of the Clean Water Act, “as the management
    agency for all activities on NFS [i.e., National Forest
    System] lands,” with responsibility “to implement
    provisions of water quality management plans.” See
    
    33 U.S.C. § 1288
    (c). The MAA references the Forest
    Service’s report entitled “Water Quality Management for
    National Forest System Lands in California” (also referred
    to as the “Forest Service 208 Report”), which “describes
    current Forest Service practices and procedures for
    protection of water quality.” The MAA states that the “State
    Board [a]grees” that “[t]he practices and procedures set forth
    in the Forest Service 208 Report constitute sound water
    quality protection and improvement on NFS lands,” except
    with respect to certain issues that were enumerated in an
    attachment. As to the items in that attachment, additional
    “refinement” was needed before they could also be accepted,
    like the remaining practices and procedures, as “Best
    Management Practices (BMPs).”
    12         CSERC V. STANISLAUS NAT’L FOREST
    The MAA further states that “[i]t is contemplated by this
    agreement” that the Forest Service’s “reasonable
    implementation” of the BMPs and the MAA “will constitute
    compliance with Section 13260, subdivision (a) of Section
    13263, and subdivision (b) of Section 13264, Water Code,”
    and that the regional boards will waive the reporting and
    discharge requirements of those sections. The MAA also
    states that “nothing herein will be construed in any way as
    limiting the authority of the State Board, or the Regional
    Boards in carrying out their legal responsibilities for
    management, or regulation of water quality.”
    In 1999, the California Legislature amended the Porter-
    Cologne Act to require the State Board to “prepare a detailed
    program” for “implementing the state’s nonpoint source
    management plan.” See CAL. WATER CODE § 13369(a).
    This implementation program must include measures to
    promote the use of “best management practices.” Id.
    § 13369(b)(1). In carrying out this directive, the State Board
    in 2004 adopted the “Policy for Implementation and
    Enforcement of the Nonpoint Source Pollution Control
    Program” (“2004 NPS Policy”). This policy states that “all
    current and proposed NPS [i.e., nonpoint source] discharges
    must be regulated under WDRs, waivers of WDRs, or a
    basin plan prohibition, or some combination of these
    administrative tools.”        However, the Policy also
    acknowledges that “[t]here are agencies . . . with the
    authority to implement programs to meet water quality
    objectives and protect beneficial uses” and that “[s]everal of
    these agencies are formally linked” to the State Board and
    regional boards through “management agency agreements.”
    The Policy further notes that, while “[a]nother agency’s
    actions pursuant to an . . . MAA” do not automatically fulfill
    a regional board’s obligations “to address the relevant NPS
    discharges,” they “can serve . . . as the basis, in part or in
    CSERC V. STANISLAUS NAT’L FOREST                13
    whole, for a [regional board] waiver of WDRs for the
    activities covered in these agreements.”
    In 2009, the State Board adopted a resolution directing
    staff “to develop and propose a statewide approach to
    address activities on national forest system lands.” In
    response, the Board’s staff prepared a draft of a formal
    waiver of WDRs for nonpoint source activities on federal
    lands, but the Board ultimately rejected the proposal in late
    2011. The State Board also considered adopting a
    “statewide approach to addressing the water quality impacts
    from livestock grazing” on both public and private lands, but
    in 2015 it ultimately rejected that concept as well. Instead,
    the State Board left it to each regional board to “determine
    which actions” concerning livestock operations, “including
    regulatory actions and effective non-regulatory efforts for
    BMP implementation, are best suited to protect water
    quality.” As the parties have noted in their post-argument
    submissions, the relevant regional board is continuing to
    work with the Forest Service to develop nonpoint source
    permits covering Forest Service lands.
    C
    The Stanislaus National Forest is located in California’s
    Sierra Nevada Mountains, northwest of Yosemite National
    Park. The Forest Service has issued permits allowing
    livestock grazing in the three allotments within the Park that
    are at issue here—the Bell Meadow, Eagle Meadow, and
    Herring Creek Allotments (collectively, the “BEH
    Allotments”). According to a Forest Service report, the
    “BEH meadows have had a history of grazing and
    overgrazing going back to the 1890s.” In the 1920s, the
    number of livestock allowed to graze in the BEH meadows
    was “6 to 10 times more than present levels,” but stocking
    levels were reduced in the 1970s.
    14         CSERC V. STANISLAUS NAT’L FOREST
    The current grazing permits for the Bell Meadow, Eagle
    Meadow, and Herring Creek Allotments were issued,
    respectively, in November 2016, March 2012, and June
    2016; each was modified in 2017. In addition to setting
    certain conditions in the permits themselves, the Forest
    Service also issues annual operating instructions that contain
    specific instructions that are “responsive to conditions that
    the Forest Service could not or may not have anticipated.”
    Oregon Nat. Desert Ass’n v. U.S. Forest Serv., 
    465 F.3d 977
    ,
    980–81 (9th Cir. 2006). At the time the district court ruled,
    the most recent annual operating instructions for the BEH
    Allotments had been issued in May and June 2018.
    According to Plaintiff CSERC, the Forest Service’s
    allowance of livestock grazing in the BEH Allotments has
    led to fecal matter runoff that has polluted streams in the
    area. In particular, CSERC contends that local streams
    contain levels of fecal coliform bacteria in excess of the
    relevant water quality objective set by the regional board.
    The BEH Allotments fall under the jurisdiction of the
    Central Valley Regional Water Quality Control Board
    (“Central Valley Regional Board”), whose basin plan
    (“Basin Plan”) defines the beneficial uses for the subject
    waterways and the water quality objectives that would
    protect those beneficial uses. See supra at 8–9. CSERC
    contends that the designated beneficial uses for several of the
    relevant waterways include “Water Contact Recreation.”
    That term refers to “recreational activities,” such as
    “swimming, wading,” and “fishing,” that “involv[e] body
    contact with water, where ingestion of water is reasonably
    possible.” In setting the “water quality objective” that would
    protect this beneficial use, the Basin Plan states that (1) the
    “fecal coliform concentration” in the water may not “exceed
    a geometric mean of 200/100 ml” based on at least “five
    samples for any 30-day period”; and (2) no more than “ten
    CSERC V. STANISLAUS NAT’L FOREST                15
    percent of the total number of samples taken during any 30-
    day period [may] exceed 400/100 ml.” Between 2009 and
    2017, CSERC conducted tests on various streams in the BEH
    Allotments, as well as elsewhere. As the district court noted,
    Plaintiffs contend that CSERC’s data “demonstrate
    136 violations” of the water quality objective “for fecal
    coliform on the Bell Creek allotment, 12 on the Eagle
    Meadow allotment, and 23 on the Herring Creek allotment.”
    Indeed, CSERC’s testing data led to two of the local streams
    being included in the list of “impaired waterways” that the
    State is required to submit to the EPA under § 303(d) of the
    Clean Water Act. See 
    33 U.S.C. § 1313
    (d). In listing those
    streams, the Central Valley Regional Board concluded that
    “grazing animals are a likely potential source of indicator
    bacteria to these streams.”
    Alleging that pollution from livestock grazing was
    impairing their members’ ability to recreate in the relevant
    areas of the Stanislaus National Forest, Plaintiffs CSERC
    and SFL filed this suit in March 2017 against the Stanislaus
    National Forest, the Forest Service, and the then-Forest
    Supervisor in her official capacity (together, the
    “Government”). Because Plaintiffs’ suit sought injunctive
    relief modifying the grazing arrangements in the BEH
    Allotments, the district court allowed the holders of the
    relevant grazing permits, together with several interested
    organizations (viz., the California Farm Bureau Federation,
    California Cattlemen’s Association, and the Stanislaus
    National Forest Grazing Permittees Association) to
    intervene as Defendants (collectively, the “Intervenors”).
    As the case comes to us, the only claim at issue is the
    first cause of action in Plaintiffs’ operative Third Amended
    Complaint, which is brought under the Administrative
    Procedure Act (“APA”) and which alleges that the
    16         CSERC V. STANISLAUS NAT’L FOREST
    Government has violated § 313 of the Clean Water Act by
    failing to comply with several requirements of the Porter-
    Cologne Act. See Marble Mountain Audubon Soc’y v. Rice,
    
    914 F.2d 179
    , 183 (9th Cir. 1990) (holding that the “judicial
    review provision[s] of the [APA] permit[] private citizens to
    sue for alleged state water quality control violations from
    nonpoint sources”) (citing Oregon Nat. Res. Council v. U.S.
    Forest Serv., 
    834 F.2d 842
    , 848–52 (9th Cir. 1987)).
    Specifically, Plaintiffs allege that the Government has
    violated the Porter-Cologne Act in two respects. First,
    Plaintiffs allege that the Government made new or modified
    discharges of waste without filing a discharge report as
    required by § 13260 and without first obtaining WDRs or a
    waiver in accordance with § 13264(a). Second, Plaintiffs
    allege that the Government violated the Porter-Cologne Act
    by “authoriz[ing] livestock grazing on the BEH allotments
    that has caused violations of state water quality standards for
    fecal coliform bacteria,” as set forth in the Basin Plan.
    After the parties filed cross-motions for summary
    judgment, the district court granted summary judgment to
    the Government and the Intervenors. After entry of final
    judgment, Plaintiffs timely appealed.
    II
    We have statutory jurisdiction pursuant to 
    28 U.S.C. § 1291
    , and we review the district court’s grant of summary
    judgment de novo. See Dominguez-Curry v. Nevada Transp.
    Dep’t, 
    424 F.3d 1027
    , 1033 (9th Cir. 2005).
    Although Defendants have not challenged Plaintiffs’
    Article III standing, we have “an independent obligation to
    assure that standing exists, regardless of whether it is
    challenged by any of the parties.” Summers v. Earth Island
    Inst., 
    555 U.S. 488
    , 499 (2009). We conclude that Plaintiffs
    CSERC V. STANISLAUS NAT’L FOREST                  17
    have standing under the associational standing doctrine
    recognized in Hunt v. Washington State Apple Advertising
    Commission, 
    432 U.S. 333
     (1977).
    Under that doctrine, an association may establish
    standing as the representative of its members by showing
    that “(a) its members would otherwise have standing to sue
    in their own right; (b) the interests it seeks to protect are
    germane to the organization’s purpose; and (c) neither the
    claim asserted nor the relief requested requires the
    participation of individual members in the lawsuit.” 
    Id. at 343
    . The second and third requirements are plainly satisfied
    here: Plaintiffs’ claims alleging violation of the Porter-
    Cologne Act are clearly germane to CSERC’s mission to
    “identify threats to the environment in the central region of
    the Sierra Nevada” and to SFL’s “work[] to protect and
    restore the forests, wildlands, wildlife, and watersheds of the
    Sierra Nevada.”        Nothing about the adjudication of
    Plaintiffs’ claims for declaratory and injunctive relief would
    require the participation of individual members. And as to
    the first requirement, Plaintiffs presented, at summary
    judgment, declarations from members that sufficiently
    establish their individual Article III standing.
    “[T]o satisfy Article III’s standing requirements, a
    plaintiff must show (1) it has suffered an ‘injury in fact’ that
    is (a) concrete and particularized and (b) actual or imminent,
    not conjectural or hypothetical; (2) the injury is fairly
    traceable to the challenged action of the defendant; and (3) it
    is likely, as opposed to merely speculative, that the injury
    will be redressed by a favorable decision.” Friends of the
    Earth, Inc. v. Laidlaw Env’t Servs. (TOC), Inc., 
    528 U.S. 167
    , 180–81 (2000) (citation omitted). At least one member
    of each organization averred that she regularly hikes in all
    three Allotments and that the physical impacts of the cattle
    18         CSERC V. STANISLAUS NAT’L FOREST
    grazing impair her present and anticipated enjoyment of the
    area, including its creeks and streams. This showing is
    sufficient to establish an Article III injury-in-fact. See
    Inland Empire Waterkeeper v. Corona Clay Co., 
    17 F.4th 825
    , 832 (9th Cir. 2021) (finding Article III standing where
    plaintiff organization “presented sworn testimony from
    several of its members that they lived near the Creek, used it
    for recreation, and that pollution from the discharged storm
    water impacted their present and anticipated enjoyment of
    the waterway”). Construing the evidence in the light most
    favorable to Plaintiffs, they have made a sufficient showing
    that these adverse impacts are attributable, at least in part, to
    the challenged cattle grazing and that those injuries would
    be redressed by a reduction or elimination of such grazing.
    See Lujan v. Defenders of Wildlife, 
    504 U.S. 555
    , 561
    (1992).
    Accordingly, Plaintiffs have standing, and we may
    proceed to the merits.
    III
    As noted earlier, § 313 of the Clean Water Act states that
    any agency that has “jurisdiction over any property or
    facility” or that engages in activities that “result[], or which
    may result, in the discharge or runoff of pollutants” must
    “comply with,” inter alia, all “State . . . and local
    requirements, administrative authority, and process and
    sanctions respecting the control and abatement of water
    pollution in the same manner, and to the same extent as[,]
    any nongovernmental entity.”           
    33 U.S.C. § 1323
    (a).
    Plaintiffs’ sole remaining cause of action is based
    exclusively on the Government’s alleged failure to comply
    with this provision, and we therefore have no occasion to
    address whether the Government’s challenged conduct here
    independently violated any other provision of the Act. In
    CSERC V. STANISLAUS NAT’L FOREST                          19
    alleging a violation of § 313, Plaintiffs first contend that the
    Government violated California’s Porter-Cologne Act—
    made applicable by § 313—by failing to file a discharge
    report and by discharging waste without first obtaining either
    WDRs or a waiver. 3 See CAL. WATER CODE §§ 13260,
    13264(a). We conclude that the district court properly
    granted summary judgment to Defendants on this issue.
    A
    In reviewing the basic framework of the Porter-Cologne
    Act, we explained earlier that, absent a waiver of the
    reporting requirement under § 13269 of the California Water
    Code, § 13260(a) generally requires any person
    “discharging waste, or proposing to discharge waste,” to file
    a “report of the discharge” with the relevant regional board.
    CAL. WATER CODE § 13260(a)(1). Unless and until the
    regional board issues either WDRs under § 13263 or a
    waiver under § 13269, the person shall not “initiate any new
    discharge of waste or make any material changes in any
    discharge.” Id. § 13264(a).
    However, the 1981 MAA jointly agreed to by the State
    Board and the Forest Service specifically addresses those
    obligations in the following terms:
    It is contemplated by this agreement that
    Forest Service reasonable implementation of
    those practices and procedures and of this
    3
    The parties vigorously dispute whether the Forest Service counts
    as a discharger who is subject to the relevant provisions of the Porter-
    Cologne Act. Because we dispose of this case on other grounds, we need
    not decide this issue. We therefore assume arguendo, for purposes of
    this appeal, that the Forest Service is a discharger subject to the Porter-
    Cologne Act.
    20          CSERC V. STANISLAUS NAT’L FOREST
    agreement will constitute compliance with
    Section 13260, subdivision (a) of Section
    13263, and subdivision (b) of Section 13264,
    Water Code. It is further contemplated that
    these provisions requiring a report of
    proposed discharge and issuance of waste
    discharge requirements for nonpoint source
    discharges will be waived by the Regional
    Board pursuant to Section 13269, Water
    Code, provided that the Forest Service
    reasonably implements those practices and
    procedures and the provisions of this
    agreement.
    The referenced “practices and procedures” are the BMPs set
    forth in the Forest Service 208 Report (or, in the case of a
    few specific issues, those to be agreed upon by the State
    Board and the Forest Service), and these BMPs were
    expressly declared to “constitute sound water quality
    protection and improvement on NFS lands.” See supra
    at 11. By its plain terms, therefore, the MAA provides that
    implementation of those BMPs “will constitute compliance”
    with (1) the reporting requirement of “Section 13260”;
    (2) the obligation to comply with WDRs in § 13263; and
    (3) the obligation in § 13264 to refrain from discharges
    absent WDRs or a waiver. 4 The MAA also expressly states
    that it is “further contemplated” that the obligations to file a
    report or to obtain WDRs “will be waived by the Regional
    Board pursuant to Section 13269.” See CAL. WATER CODE
    § 13269(a)(1) (authorizing waiver of the obligations in
    “subdivisions (a) and (c) of Section 13260” and “subdivision
    4
    The MAA references “subdivision (b) of Section 13264,” which is
    the provision providing for enforcement of the obligations set forth in
    § 13264(a).
    CSERC V. STANISLAUS NAT’L FOREST                 21
    (a) of Section 13264”). The MAA thus clearly establishes
    that, in lieu of filing reports and obtaining WDRs, the Forest
    Service will instead implement the agreed-upon BMPs and
    the provisions of the MAA.
    B
    The MAA also expressly states, however, nothing in it
    “will be construed in any way as limiting the authority of the
    State Board, or the Regional Boards in carrying out their
    legal responsibilities for management, or regulation of water
    quality.” Moreover, we held in Northwest Indian Cemetery
    Protective Ass’n v. Peterson, 
    795 F.2d 688
     (9th Cir. 1986),
    rev’d on other grounds, 
    485 U.S. 439
     (1988), that the 1981
    MAA did not displace the relevant basin plans of the
    regional boards. Id. at 697. As we explained, the BMPs set
    forth in the MAA “are merely a means to achieve” the water
    quality objectives of those plans. Id. Thus, if the State Board
    or a regional board concluded that the MAA was no longer
    an adequate substitute for compliance with the ordinary
    reporting and permitting processes envisioned in §§ 13260,
    13263, and 13264, those entities could take appropriate steps
    to abrogate the MAA and to require compliance with those
    ordinary processes in accordance with their terms. Plaintiffs
    contend that the MAA has been superseded here, but we
    disagree.
    Plaintiffs assert that the MAA was superseded by the
    State Board’s adoption of the 2004 NPS Policy, but this
    argument is refuted by the text of that document. The Policy
    expressly references, as still operative, the “memoranda of
    understanding (MOUs) or management agency agreements
    (MAAs)” that the State Board and regional boards have with
    other agencies. Moreover, the Policy reaffirms that, in the
    case of an MAA in which the State Board has “designate[d]
    another agency as a management agency to take the lead in
    22         CSERC V. STANISLAUS NAT’L FOREST
    implementing NPS pollution control,” the “fundamental
    purpose” of such an MAA is to achieve “at least the same
    degree of control over NPS pollution as could be attained
    through direct regulation under [State Board or regional
    board] authority, but to do so more efficiently.” Because the
    1981 MAA expressly recognizes the Forest Service’s
    designation as “the management agency for all activities on
    NFS lands,” this language from the 2004 NPS Policy
    confirms that the actions of the Forest Service under the
    MAA remain a substitute means for achieving the same
    water quality control “as could be obtained through direct
    regulation” using the regional boards’ conventional tools
    (such as reports, WDRs, and waivers).
    To be sure, the Policy further states that neither the State
    Board nor the regional boards have given up their ultimate
    authority: neither may “delegate their NPS authorities and
    responsibilities to another agency,” and they “may not
    indefinitely defer taking necessary action if another agency
    is not properly addressing a NPS problem.” But this
    language confirms that the State Board, or the relevant
    regional board, must take affirmative action to exercise that
    authority, and thereby to abrogate, amend, or supersede the
    terms of an MAA. The 2004 NPS Policy, by itself, does not
    take that step.
    The State Board in recent years has expressed
    dissatisfaction with the MAA and has considered a variety
    of alternatives, including a formal detailed waiver of WDRs
    for nonpoint sources on federal lands and a statewide
    approach specific to public and private livestock grazing.
    See supra at 13. The State Board ultimately rejected these
    options and instead left the matter in the hands of the
    regional boards. The Central Valley Regional Board has
    been working with the Forest Service on that issue, but it has
    CSERC V. STANISLAUS NAT’L FOREST                          23
    thus far not taken affirmative steps to vitiate the MAA. On
    the contrary, the current Basin Plan expressly reaffirms that
    the regional board “abides” by the existing MAAs, including
    specifically the 1981 MAA with the Forest Service. Indeed,
    the Basin Plan reiterates that that the MAA “waives
    discharge requirements” for certain Forest Service NPS
    discharges, provided that the Forest Service implements the
    BMPs and the MAA.
    Despite this overwhelming confirmation that the MAA
    remains operative and continues to waive compliance with
    the reporting and permitting requirements of §§ 13260,
    13263, and 13264, Plaintiffs assert that the Forest Service
    admitted in a draft Environmental Impact Statement
    concerning the BEH Allotments that it is required to obtain
    WDRs or a waiver from the regional board. But the
    statement they cite merely adverts to the Forest Service’s
    ongoing discussions to develop relevant permits that would,
    to that extent, supersede the MAA. See also supra at 13.
    That the Forest Service is working with the regional board
    on options for displacing the MAA does not establish that
    the MAA has already been displaced. 5
    Accordingly, we conclude that Plaintiffs failed to show
    that the Government violated the reporting and permitting
    requirements of §§ 13260, 13263, and 13264. We therefore
    5
    Plaintiffs also note that the Forest Service stated, in litigation
    concerning logging in another part of the State, that it had applied for an
    express waiver from the relevant regional board. It is not clear that the
    mere application for a waiver to cover a specific subject reflects any
    concession that the waiver was required to be sought in that case or that
    waivers are required generally. In any event, the cited suit was dismissed
    voluntarily and can give rise to no estoppel against the Government here.
    United States v. Mendoza, 
    464 U.S. 154
    , 160 (1984); Amadeo v.
    Principal Mut. Life Ins. Co., 
    290 F.3d 1152
    , 1159 (9th Cir. 2002).
    24         CSERC V. STANISLAUS NAT’L FOREST
    affirm the district court’s grant of summary judgment on
    these issues.
    IV
    Plaintiffs also allege that the Government violated § 313
    of the Clean Water Act by authorizing livestock grazing that
    caused runoff that led to fecal coliform levels in local
    waterways in excess of the relevant water quality objectives
    in the Central Valley Regional Board’s Basin Plan. This
    argument fails, because these Basin Plan objectives do not
    directly apply, of their own force, to individual dischargers
    but instead reflect standards that regulators must take into
    account in fashioning the requirements that do apply to
    dischargers (such as WDRs, waivers, and basin-plan
    prohibitions).
    Plaintiffs contend that we have already held that a basin
    plan’s objectives can be enforced against specific projects
    under § 313, citing our decisions in Northwest Indian
    Cemetery, 
    795 F.2d at 697
    , and Marble Mountain, 
    914 F.2d at
    182–83. But the judicial enforceability of such water
    quality objectives against specific projects does not appear
    to have been contested by the defendants in those cases or
    otherwise presented as an issue for our resolution. Instead,
    in Northwest Indian Cemetery, the Government argued that
    the water quality standards in the basin plan had been
    formally or effectively superseded by the BMPs in the 1981
    MAA, and we rejected that argument. As we explained, the
    BMPs did not displace the water quality standards but were
    “merely a means to achieve” them, and “[a]dherence to the
    BMPs does not automatically ensure that the applicable state
    standards are being met.” 
    795 F.2d at 697
    . The Government
    did not otherwise contest that a court could enjoin a specific
    project that was alleged to result in a violation of a water
    quality objective, and we therefore had no occasion to
    CSERC V. STANISLAUS NAT’L FOREST                   25
    address whether that concession was or was not correct.
    Likewise, in Marble Mountain, the Government argued that
    the plaintiffs had not properly challenged, and could not
    successfully challenge, “the Forest Service’s interpretation
    and application” of the relevant water quality objectives, but
    it did not contest that those objectives were directly
    enforceable against the particular project at issue. 
    914 F.2d at
    182–83. We rejected the Government’s arguments,
    holding only that “the plaintiffs properly challenged the
    [Government’s] interpretation of state water quality
    objectives,” and we remanded the case for the district court
    “to address the merits of that claim.” 
    Id. at 183
    ; cf. also
    Oregon Nat. Res. Council, 
    834 F.2d at 852
     (rejecting, as
    oversimplified, the district court’s analysis of Oregon
    regulations concerning water quality standards and
    remanding for district court to determine “whether the
    activities . . . will violate the applicable regulations”). Here,
    however, we are squarely presented with the direct-
    enforceability issue that was uncontested and taken for
    granted in those cases.
    As our detailed summary of the Porter-Cologne Act
    makes clear, the water quality objectives established by a
    regional board in a basin plan provide the relevant standards
    that must guide the overall package of regulatory actions that
    the board determines “are necessary to achieve the
    objectives.” See CAL. WATER CODE § 13242(a). Thus, in
    requiring the board to establish such objectives, the Porter-
    Cologne Act also requires it to develop a “program of
    implementation needed for achieving water quality
    objectives.” Id. § 13050(j)(3) (emphasis added). The tools
    for implementation provided by the statute include three
    different methods for imposing specific obligations on
    dischargers. First, the basin plan itself may set forth
    particular prohibitions “specify[ing] certain conditions or
    26         CSERC V. STANISLAUS NAT’L FOREST
    areas where the discharge of waste, or certain types of waste,
    will not be permitted.” Id. § 13243. Second, the board may
    impose “waste discharge requirements” under § 13263(a),
    which function as “permits” authorizing the specified
    discharges under the enumerated conditions. Id. § 13374.
    Third, the board may grant “waivers” under § 13269, which
    must contain conditions restricting the discharges covered
    by the waivers. Id. § 13269(a)(2). In invoking each of these
    tools, the regional board must consider the relevant water
    quality standards that it is seeking to implement. In
    particular, in issuing WDRs, the board must consider the
    beneficial uses of the relevant waterways, the “water quality
    objectives reasonably required” to protect those uses, and,
    importantly, “other waste discharges” that may contribute to
    a failure to achieve those objectives. Id. § 13263(a).
    Waivers may only be issued if the board determines that they
    are consistent with the relevant basin plan, and any such
    waiver must contain monitoring requirements to allow the
    board to evaluate “the adequacy and effectiveness of the
    waiver’s conditions.” Id. § 13269(a)(2).
    Once the board translates the water quality objectives
    into particular prohibitions, WDRs, and waivers imposing
    restrictions on specific discharges or categories of
    discharges, the board and the California Attorney General
    may take appropriate steps to enforce those obligations on
    individual dischargers. For example, the Porter-Cologne
    Act allows a regional board to issue cease and desist orders
    in the event of an actual or threatened discharge in violation
    of WDRs or basin plan prohibitions. See id. § 13301. The
    board can also request that the Attorney General file an
    action for civil penalties for any discharges “in violation of
    a waste discharge requirement, waiver condition,
    certification, or other order or prohibition.” Id. § 13350(a);
    see also id. § 13350(g). The board can likewise request that
    CSERC V. STANISLAUS NAT’L FOREST                  27
    the Attorney General file suit enjoining, and seeking civil
    liability for, unauthorized discharges made in violation of
    § 13264(a). See id. §§ 13264(b), 13265(a), (b)(2). The
    board can also impose civil liability for such violations of
    § 13264 administratively. Id. § 13265(b)(1).
    The parties have not cited, nor have we found, any
    provision of the Porter-Cologne Act that would make a
    discharger directly liable for violating a water quality
    objective contained in a basin plan that is not contained in
    applicable WDRs, waivers, or prohibitions. Cf. County of
    Sacramento v. State Water Res. Control Bd., 
    64 Cal. Rptr. 3d 302
    , 305–07 (Ct. App. 2007) (upholding inclusion, in
    WDRs applicable to a county facility, of the numerical water
    quality objective for a particular bacterium in the basin plan).
    To the extent that discharges authorized by the board (e.g.,
    through WDRs or waivers) have resulted in a failure to attain
    water quality objectives, that might lead the board to modify
    previously issued WDRs or to terminate a waiver. See CAL.
    WATER CODE § 13263(e) (stating that board, on its own
    motion, “may review and revise” WDRs); id. § 13263(g)
    (stating that there are no “vested right[s]” to continue
    discharges); id. § 13269(a)(2) (providing that waivers “may
    be terminated at any time”). Moreover, because the regional
    board sets water quality objectives by considering the
    “[w]ater quality conditions that [can] reasonably be achieved
    through the coordinated control of all factors which affect
    water quality in the area,” id. § 13241(c) (emphasis added),
    the board could decide to respond to a failure to meet those
    objectives by restricting some uses deemed less valuable,
    while allowing the WDRs for other uses to remain
    unchanged. The board’s actions in addressing such a failure
    could also conceivably lead to administrative action, or a
    petition for a writ of mandate, against the regional board.
    See id. § 13320(a) (providing for state board review of
    28         CSERC V. STANISLAUS NAT’L FOREST
    regional board actions or failure to act); id. § 13330(b)
    (authorizing writ of mandate review in state court). But a
    discharge that otherwise complies with applicable WDRs,
    waivers, or prohibitions does not violate the Porter-Cologne
    Act merely because the water quality objectives are not
    being met.
    For the reasons we have previously explained, the
    Government has not been shown to have violated the
    reporting or discharge restrictions of §§ 13260, 13263, or
    13264. Nor have Plaintiffs contended that the Government
    has violated any prohibition contained within the relevant
    basin plan. Cf. id. § 13243. Although the regional board
    thus has not translated its water quality objectives into
    prohibitions, WDRs, or waivers that are directly enforceable
    against the Government, Plaintiffs ask us, in effect,
    judicially to assume that task and to hold that the
    Government’s allowance of livestock grazing should be
    prohibited or restricted because it assertedly contributes,
    perhaps with other contributing causes, to a failure to
    achieve certain of the water quality objectives of the basin
    plan. This we cannot do. The Porter-Cologne Act assigns
    the task of developing a program of implementation of water
    quality objectives to the regional board, which can assess the
    problem as a whole and in light of other competing sources.
    See id. § 13050(j)(3). It does not assign that task to the
    federal courts.
    For the foregoing reasons, we affirm the district court’s
    grant of summary judgment to Defendants with respect to
    Plaintiffs’ claims based on asserted violations of the basis
    plan’s water quality objectives.

    We affirm the district court’s denial of summary
    judgment for Plaintiffs and grant of summary judgment for
    Defendants.
