    MANSFIELD, Justice.
    Two social justice organizations have brought this case against the
    State of Iowa, four different state agencies, and a number of state officials.
    Relying on the public trust doctrine, under which the State is the “trustee”
    of the State’s navigable waters, they seek to force the defendants to enact
    legislation that will compel Iowa farmers to take steps that will have the
    effect of significantly reducing levels of nitrogen and phosphorus in the
    Raccoon River. This, they allege, will improve their members’ aesthetic
    and recreational use of the river and bring about reductions in their water
    bills.
    The defendants moved to dismiss the petition based on lack of
    standing,     nonjusticiability,   and   failure   to   exhaust   administrative
    remedies.     The district court denied the motion.        On appeal, we now
    conclude that the motion should have been granted on the first two
    grounds. In our view, the attenuated causation theory of the petition is
    not enough to establish that the plaintiffs’ members have suffered a
    concrete injury at the hands of the defendants that a favorable court
    decision is likely to redress.      And, we believe the plaintiffs’ effort to
    repurpose the historically narrow public trust doctrine to solve a complex
    environmental problem presents a nonjusticiable political question.
    Therefore, we reverse the district court’s order and remand with
    instructions to dismiss the petition.
    I. Factual and Procedural Background.
    A. The Nature of the Litigation and the Parties. This is an action
    for declaratory relief and to compel the State of Iowa to adopt “a Raccoon
    River remedial plan with mandatory agricultural water pollution controls.”
    The plaintiffs are Iowa Citizens for Community Improvement (ICCI)
    and Food and Water Watch (FWW). ICCI has 5100 members, of whom
    5
    2404 reside in Polk County. Many of those members recreate in, on, or
    around the Raccoon River in Polk County. ICCI’s organizational priorities
    include “fighting factory farms and campaigning to clean up Iowa’s
    polluted waterways, as well as advancing worker justice, racial justice, and
    immigrants’ rights.”
    FWW “champions healthy food and clean water for all by standing
    up to corporations that put profits before people and advocating for a
    democracy that improves people’s lives and protects the environment.”
    FWW has 18,400 “members and supporters” in Iowa, and 2804 “members
    and supporters” in Polk County.
    The defendants are the State of Iowa, the Iowa Department of
    Natural Resources (DNR), the director of DNR, the Environmental
    Protection Commission, the members of the Environmental Protection
    Commission, the Natural Resource Commission, the members of the
    Natural Resource Commission, the Iowa Department of Agriculture and
    Land Stewardship, and the secretary of agriculture. Thus, the petition
    names twenty-three separate defendants.
    B. Factual Allegations in the Petition. The petition alleges that
    Iowa leads the nation in corn and pork production, and is one of the
    leaders in soybean production. But according to the petition, this food
    production comes at a cost. Iowa farmers “apply vast amounts of fertilizer
    to grow corn and soybeans.” They also apply manure from animal feeding
    operations to corn and soybeans as fertilizer.      Fertilizer and manure
    contain nitrogen, which is converted to nitrates.       They also contain
    phosphorus.
    Some of these nitrates and phosphorus run off into the Raccoon
    River watershed. They contribute to the growth of cyanobacteria, which
    excrete cyanotoxins.
    6
    Climate change—specifically, higher air and water temperatures and
    more frequent heavy rains—have also led to more nitrates and phosphorus
    in the watershed and more cyanobacteria proliferation.
    Since 1974, average nitrate levels in the Raccoon River have
    increased significantly. The Des Moines Water Works has had to incur
    costs to remove nitrates from Raccoon River water so the Class C drinking
    water standard of 10 mg/l is met before the water actually reaches the
    customer. Currently, there is no mandatory state plan for the reduction
    of nitrates in the Raccoon River.
    DNR has authorized animal feeding operations to apply manure to
    frozen, snow-covered ground, which has resulted in discharges to
    navigable waters. The Iowa legislature has appropriated insufficient funds
    to DNR to implement and enforce water quality protections at animal
    feeding operations. Legislation to impose a moratorium on new medium
    and large animal feeding operations has been introduced in the Iowa
    legislature but has not passed.
    In 2008, environmental groups inside and outside Iowa tried to get
    the Federal Environmental Protection Agency (EPA) to promulgate numeric
    water quality standards for nitrogen and phosphorus. The EPA said no.
    Instead, in 2011, the EPA announced a policy to defer to states on nitrogen
    and phosphorus regulation.          EPA recommended states implement
    “voluntary agricultural nonpoint source controls.” Efforts to overturn the
    EPA’s decision not to act were unsuccessful.          See generally Gulf
    Restoration Network v. McCarthy, 
    783 F.3d 227
    , 243–44 (5th Cir. 2015)
    (holding that the EPA had discretion not to issue water quality standards
    for nitrogen and phosphorus if it provided a reasonable explanation).
    Nitrogen and phosphorus entering the Gulf of Mexico from, in part,
    the Mississippi River Basin “has created a hypoxic zone spanning
    7
    thousands of square miles.” A 2008 Gulf Hypoxia Action Plan calls for
    Iowa and other states along the Mississippi River to reduce nitrogen and
    phosphorus loadings to the Gulf of Mexico so that a 45% reduction in total
    levels is achieved.
    In 2013, the Iowa legislature enacted legislation to authorize and
    fund the Iowa Nutrient Reduction Strategy. 2013 Iowa Acts ch. 132, § 60
    (codified at Iowa Code § 466B.42 (2014)). This strategy identifies best
    management practices to reduce nitrogen and phosphorus discharges into
    surface waters but does not require adoption or implementation of any
    specific measure or practice.      Only limited progress has been made;
    statewide   improvements    will   require   “a   much   greater   degree   of
    implementation than has occurred so far.”
    In the 2018 session, the Iowa legislature enacted section 20 of
    Senate File 512, making the Iowa Nutrient Reduction Strategy the state
    policy for nitrogen and phosphorus water pollution controls. 2018 Iowa
    Acts ch. 1001, § 20 (codified at Iowa Code § 455B.177(3) (2019)).
    C. The Plaintiffs’ Legal Claims. The plaintiffs’ claims are all based
    on the public trust doctrine. The plaintiffs allege that their members are
    beneficiaries under the public trust doctrine and that the State has a duty
    to protect the public use of navigable waters and to prevent substantial
    impairment of navigable waters. They allege that the State has abdicated
    control of the meandered section of the Raccoon River to private parties by
    pursuing a “voluntary” nitrogen and phosphorus control strategy for
    agricultural nonpoint sources.
    ICCI and FWW members suffer harm in several ways. Des Moines
    Water Works, which serves the metropolitan Des Moines area and draws
    water from the Raccoon River, incurs capital, operational, maintenance,
    and monitoring costs to reduce nitrate and cyanotoxin contamination.
    8
    This results in higher costs for drinking water. ICCI and FWW members
    also have concerns about health risks from consuming water containing
    nitrates and microcystins. In addition, ICCI and FWW members suffer
    aesthetic injury and injury to their recreational use of the Raccoon River
    for swimming and kayaking. There have been several days when levels of
    microcystins impaired swimming and kayaking in the river.
    The plaintiffs seek both declaratory and injunctive relief, at a high
    level of generality. In brief, they seek a declaration that the State violated
    the public trust doctrine by not protecting the public’s recreational and
    drinking water use of navigable waters. They also seek a declaration that
    section 20 of Senate File 512 is null and void as inconsistent with the
    public trust doctrine. They further seek an injunction against the State
    from taking any further action that would violate the public trust doctrine.
    They ask for an injunction requiring the State “to adopt and implement a
    mandatory remedial plan to restore and protect public use that requires
    agricultural nonpoint sources and CAFO’s [confined animal feeding
    operations] to implement nitrogen and phosphorus limitations in the
    Raccoon River watershed.” And, finally, until that plan is working, they
    seek an injunction against the State authorizing the construction and
    operation of new medium and large animal feeding operations and
    confined animal feeding operations in the Raccoon River watershed.
    D. The Motion to Dismiss. On April 29, 2019, the defendants
    moved to dismiss the petition based on lack of standing, nonjusticiability,
    and failure to exhaust administrative remedies. On May 10, the plaintiffs
    filed a resistance.   The district court held a hearing on June 19.       On
    September 10, the court issued an order denying the defendants’ motion
    to dismiss.
    9
    The defendants sought an interlocutory appeal, and we granted their
    application. We retained the appeal.
    II. Standard of Review.
    We review questions of standing and whether an action should be
    dismissed as nonjusticiable for correction of errors at law. State ex rel.
    Dickey v. Besler, 
    954 N.W.2d 425
    , 430 (Iowa 2021).
    III. Legal Analysis.
    A. The Public Trust Doctrine. Although the merits of this case
    are not before us, some understanding of the public trust doctrine is
    required to address the standing and justiciability issues that are before
    us.1
    The public trust doctrine “is based on the notion that the State is a
    steward of our natural resources.” Fencl v. City of Harpers Ferry, 
    620 N.W.2d 808
    , 814 (Iowa 2000) (en banc). But it “has a narrow scope.” 
    Id. at 813
    . It “originally applied to the beds of navigable waters, but has now
    expanded to embrace the public’s use of lakes and rivers for recreational
    purposes as well.” Larman v. State, 
    552 N.W.2d 158
    , 161 (Iowa 1996). It
    protects “the public’s right of access to public waters.” 
    Id.
     And, it “limits
    the State’s power to dispose of land encompassed within the public trust.”
    1Standing cannot be considered in a vacuum without reference to the source of
    the legal claims. See, e.g., State ex rel. Food & Water Watch v. State, 
    100 N.E.3d 391
    , 397
    (Ohio 2018) (per curiam) (finding there was no standing because “a plain reading of the
    statute does not support, and [the plaintiff] has not shown, that the writ sought—one
    that would mandate the promulgation of rules—will likely redress the purported injury”).
    Likewise, we have said before that “the political question grounds and the failure
    to state a claim grounds are interrelated.” King v. State, 
    818 N.W.2d 1
    , 12 (Iowa 2012).
    To determine whether a claim is within the competence of the judiciary to handle, it is
    appropriate to understand what the claim is. We do not agree with the suggestion that
    the political question doctrine cannot be raised unless the party raising it is also seeking
    to dismiss for failure to state a claim. A party can concede that a novel theory—like the
    plaintiffs’ expansive version of public trust doctrine—would state a claim and still argue
    that it would not redress the plaintiffs’ injuries and be unworkable for courts to
    administer.
    10
    
    Id.
     These two principles of public access and no private alienation are
    interrelated. Obviously, if some part of the public trust is turned over to
    a private party, then the public no longer has access to it.
    We have repeatedly discussed and applied the public trust doctrine
    as embodying these twinned notions of open access and no private
    alienation. See State v. Pettijohn, 
    899 N.W.2d 1
    , 35 (Iowa 2017) (explaining
    that the doctrine involves “the ‘paramount’ right of Iowans to use state
    waterways for navigational and recreational purposes” and noting that
    Congress declared the navigable waters leading into the Mississippi to be
    “common highways, and forever free as well to the inhabitants of said
    State, as to all other citizens of the United States”); Orr v. Mortvedt, 
    735 N.W.2d 610
    , 615 (Iowa 2007) (“The public generally has a right of access
    to navigable watercourses.”); State v. Sorensen, 
    436 N.W.2d 358
    , 362 (Iowa
    1989) (noting “the stringent limitations on the state’s power to alienate”
    public trust resources); Witke v. State Conservation Comm’n, 
    244 Iowa 261
    ,
    270–72, 
    56 N.W.2d 582
    , 588–89 (1953) (rejecting a fee for access to Clear
    Lake that was not based on an improvement or service provided); Peck v.
    Alfred Olsen Constr. Co., 
    216 Iowa 519
    , 522, 
    245 N.W. 131
    , 133 (1932)
    (“[T]he power and the duty conferred upon the state under such title is to
    maintain and promote the navigation and navigability of such lake.”). In
    State v. Meyers, we recently invoked the public trust doctrine in holding
    that a group of private property owners could not convert a navigable
    stream to their own private lake simply by blocking access to it. See 
    938 N.W.2d 205
    , 210–12 (Iowa 2020).
    Many of our cases contain language that the public trust doctrine
    protects public “use” of public trust property. For example, in State v.
    Sorensen we said,
    11
    The public trust doctrine, however, is not limited to
    navigation or commerce; it applies broadly to the public’s use
    of property, such as waterways, without ironclad parameters
    on the types of uses to be protected. See [Richard J.] Lazarus,
    [Changing Conceptions of Property and Sovereignty in Natural
    Resources: Questioning the Public Trust Doctrine, 71 Iowa Law
    Review 631, ] 649 [(1986)]; 65 C.J.S. Navigable Waters § 92,
    at 289–91 [(1966)] (Public trust purposes include “rights of
    navigation, commerce, fishing, bathing, recreation, or
    enjoyment, and other appropriate public and useful purposes,
    or such other rights as are incident to public waters at
    common law, free from obstruction and interference by private
    persons. . . .”).
    
    436 N.W.2d at 363
    . Still, even in this context “use” means access—i.e.,
    the right to enter “free from obstruction and interference by private
    persons.” 
    Id.
     (quoting 65 C.J.S. Navigable Waters § 92, at 289–91.)
    Historically, in Iowa, the public trust doctrine has not provided an
    opening for courts to weigh different uses, that is, to second-guess
    regulatory decisions made by elected bodies. In Bushby v. Washington
    County Conservation Board, we explained that “[t]he purpose of the public-
    trust doctrine is to prohibit states from ‘conveying important natural
    resources’ to private parties.” 
    654 N.W.2d 494
    , 497 (Iowa 2002) (quoting
    Fencl, 
    620 N.W.2d at 814
    ). We elaborated,
    In Iowa this doctrine was originally applied to the beds
    of navigable waters and has been expanded to include the
    recreational use of lakes and rivers. Nevertheless, the scope
    of the public-trust doctrine in Iowa is narrow, and we have
    cautioned against overextending the doctrine.          We are
    convinced that it does not serve as an impediment to legally
    sanctioned management of forested areas by the public bodies
    entrusted by law with their care.
    Id. at 498 (citations omitted). Thus, we rejected an attempt in Bushby to
    use the public trust doctrine to enjoin a clear-cutting of trees on public
    land that had been approved by the elected board of supervisors. Id. While
    the plaintiffs preferred that this reserve be left alone in its “fairly natural
    state,” the county’s representatives had determined otherwise. Id. at 495–
    12
    96; see also Magers-Fionof v. State, 
    555 N.W.2d 672
    , 674 (Iowa 1996)
    (stating it was “very doubtful” that the public trust doctrine provided a
    cause of action against the state for injury to trees grown in state parks).
    Within the last year, the Minnesota Supreme Court has held that
    the public trust doctrine did not support a claim against the Minnesota
    Department of Natural Resources alleging mismanagement, pollution, and
    impairment of a lake. White Bear Lake Restoration Ass’n ex rel. State v.
    Minn. Dep’t of Nat. Res., 
    946 N.W.2d 373
    , 376–77 (Minn. 2020).          The
    Minnesota court explained that “the doctrine was used from its inception
    to define property rights in navigable waters, entrusting them to the state
    for public use rather than allowing riparian owners to assert a private
    property interest.” Id. at 385. The court quoted from the seminal United
    States Supreme Court decision which made clear that “[t]he doctrine is
    founded upon the necessity of preserving to the public the use of navigable
    waters from private interruption and encroachment.” Id. (quoting III. Cent.
    R.R. v. Illinois, 
    146 U.S. 387
    , 436, 
    13 S. Ct. 110
    , 112 (1892)). The court
    then emphasized that the plaintiff had not alleged a violation of that duty
    “to protect public use from ‘private interruption and encroachment.” Id.
    at 386.   Instead, the plaintiff contended that the Minnesota DNR had
    issued groundwater permits that resulted in degradation of the lake. Id.
    The court observed, “We have found no precedent—and, at oral argument,
    counsel for [the plaintiff] could cite none—extending the public trust
    doctrine in this way.” Id. Finally, the court concluded,
    Twenty-five chapters within Minnesota Statutes are
    dedicated to water protection, use, and appropriation. . . .
    Because the Legislature has established structures within
    which public water use priorities are to be balanced, and no
    private encroachment or diversion to another state has been
    alleged, we see no need to extend the judiciary’s common-law
    role in this instance.
    13
    Id. (citation omitted).
    Again, the merits are not before us on this appeal. Accordingly, we
    assume for present purposes that the public trust doctrine could be
    expanded to serve the plaintiffs’ regulatory ends. The questions we need
    to answer is whether the plaintiffs have standing to bring their case and
    whether their case is justiciable.
    B. Standing. For there to be standing in federal court, a plaintiff
    must show not only (1) injury in fact, but also that the injury in fact (2) is
    fairly traceable to the defendants’ conduct and (3) is likely to be redressed
    by a favorable decision. See Lujan v. Defs. of Wildlife, 
    504 U.S. 555
    , 560–
    61, 
    112 S. Ct. 2130
    , 2136 (1992).
    [A] litigant must demonstrate that it has suffered a concrete
    and particularized injury that is either actual or imminent,
    that the injury is fairly traceable to the defendant, and that it
    is likely that a favorable decision will redress that injury.
    Massachusetts v. EPA, 
    549 U.S. 497
    , 517, 
    127 S. Ct. 1438
    , 1453 (2007).
    All   three   requirements   are     bedrock   requirements    of   Article   III
    constitutional standing in the federal courts. Lujan, 
    504 U.S. at 560
    , 
    112 S. Ct. at 2136
     (referring to the “irreducible constitutional minimum of
    standing”). They are not mere prudential considerations. 
    Id.
    In Iowa, we follow a two-prong approach.            “Our cases have
    determined that a complaining party must (1) have a specific personal or
    legal interest in the litigation and (2) be injuriously affected.” Citizens for
    Responsible Choices v. City of Shenandoah, 
    686 N.W.2d 470
    , 475 (Iowa
    2004); see also Berent v. City of Iowa City, 
    738 N.W.2d 193
    , 202 (Iowa
    2007) (“We have held that in order to have standing a party must (1) have
    a specific personal or legal interest in the litigation and (2) be injuriously
    affected.”). “This inquiry is separate from, and precedes, the merits of a
    14
    case.” Horsfield Materials, Inc. v. City of Dyersville, 
    834 N.W.2d 444
    , 452.
    (Iowa 2013).
    We have said that “[w]ith state courts, standing is a self-imposed
    rule of restraint.” Hawkeye Bancorporation v. Iowa Coll. Aid Comm’n, 
    360 N.W.2d 798
    , 802 (Iowa 1985).         But that doesn’t make the standing
    requirement any less real.      After all, article III, section 1 of the state
    constitution prohibits the judicial branch from exercising any function
    properly belonging to the legislative or executive branch. Iowa Const. art.
    III, § 1. Article V, section 6 provides that Iowa courts operate as “court[s]
    of law and equity.” Id. art. V, § 6. We have repeatedly said that the plaintiff
    “must” be injuriously affected to have standing.         See, e.g., Horsfield
    Materials, 834 N.W.2d at 452; Godfrey v. State, 
    752 N.W.2d 413
    , 418 (Iowa

    Our court has interpreted the “injuriously affected” prong of
    standing as incorporating the Lujan three-part test.        In Alons v. Iowa
    District Court, we quoted from Lujan at length, including the three-part test
    and the “irreducible constitutional minimum” language. 
    698 N.W.2d at
    867–68.        We   noted   there   were   separate,   additional   prudential
    considerations. 
    Id.
     at 868–69. We then essentially said that the federal
    test—both constitutional and prudential—was “not dissimilar from our
    own test,” and “[w]e therefore consider the federal authority persuasive.”
    
    Id. at 869
    . So, Alons aligned us with Lujan.
    In Godfrey v. State, we said that the second and third requirements
    from Lujan “largely relate to the prudential concerns we have recognized,
    and we too have relied on them to resolve standing claims in the past.”
    
    752 N.W.2d at 422
    . We identified Citizens for Responsible Choices v. City
    of Shenandoah as a case decided on traceability grounds—i.e., the second
    15
    Lujan test. 
    Id.
     (citing Citizens for Responsible Choices, 
    686 N.W.2d at 472, 475
    ). Still, regardless of whether we characterize these requirements as
    constitutional or prudential, traceability and redressability are a part of
    standing in Iowa. See also Horsfield Materials, 834 N.W.2d at 457–58
    (quoting Godfrey as recognizing the Lujan three-part test).2
    Think about it this way: If the court can’t fix your problem, if the
    judicial action you seek won’t redress it, then you are only asking for an
    advisory opinion. See Schmidt v. State, 
    909 N.W.2d 778
    , 800 (Iowa 2018)
    (“We do not issue advisory opinions.”).                In Dickey v. Iowa Ethics &
    Campaign Disclosure Board, we found that the district court lacked
    standing to hear a campaign finance reporting case where a favorable
    ruling in the case would not provide additional information to the
    petitioner. 
    943 N.W.2d 34
    , 38–41 (Iowa 2020). We stated, “Courts exist
    to hear claims brought by injured parties; [the petitioner] is not injured.”
    Id. at 40.
    In a broad sense, standing is deeply rooted in the separation-
    of-powers doctrine and the concept that the branch of
    government with the ultimate responsibility to decide the
    constitutionality of the actions of the other two branches of
    government should only exercise that power sparingly and in
    a manner that does not unnecessarily interfere with the policy
    and executory functions of the two other properly elected
    branches of government. While this policy of standing has no
    specific constitutional basis in Iowa, as it does in federal law,
    it is compatible with the overall constitutional framework in
    this state and properly reflects our role in relationship to the
    other two coequal branches of government. This ultimate
    power to decide disputes between the other branches of
    government and to determine the constitutionality of the acts
    2And   the Lujan three-part test remains part of federal standing law as well. See
    Carney v. Adams, ___ U.S. ___, ___, 
    141 S. Ct. 493

    of the other branches of government does not exist as a form
    of judicial superiority, but is a delicate and essential judicial
    responsibility found at the heart of our superior form of
    government. We have the greatest respect for the other two
    branches of government and exercise our power with the
    greatest of caution.

    When the asserted injury arises from the government’s allegedly
    unlawful failure to regulate someone else, “the plaintiff must establish ‘a
    causal connection between the injury and the conduct complained of’ and
    that the injury is ‘ “likely,” as opposed to merely “speculative,” to be
    “redressed by a favorable decision.” ’ ”             Godfrey,

    Here, it is speculative that a favorable court decision in this litigation
    would lead to a more aesthetically pleasing Raccoon River, better
    swimming and kayaking on the river, and lower water rates in the Des
    Moines metropolitan area. As already noted, to a large extent the plaintiffs
    are simply seeking broad, abstract declarations in this litigation.3 Such
    general declarations do not provide any assurance of concrete results,
    although they do herald long-term judicial involvement. The only specific
    3There  are six operative paragraphs in the prayer for relief. Paragraphs A and B
    simply seek declarations that the State has a duty to protect the public’s recreational and
    drinking water use and that the public trust doctrine has been violated. Paragraph F
    enjoins the State from taking further actions to violate the public trust doctrine. These
    are generalities.
    Paragraph C seeks a declaration that section 20 of SF 512 is null and void.
    Paragraph D purports to require the State to adopt and implement a mandatory remedial
    plan that requires agricultural nonpoint sources and CAFOs to implement nitrogen and
    phosphorus limitations in the Raccoon River watershed—with no detail beyond that. And
    paragraph E would impose a moratorium on new and expanded large and confined
    animal feeding operations until the State does so.
    17
    declaration the plaintiffs request is that section 20 of Senate File 512 be
    declared void and unconstitutional. That section reads as follows:
    The general assembly further finds and declares that it is in
    the interest of the people of Iowa to assess and reduce
    nutrients in surface waters over time by implementing the
    Iowa nutrient reduction strategy. To evaluate the progress
    achieved over time toward the goals of the Iowa nutrient
    reduction strategy and the United States environmental
    protection agency gulf hypoxia action plan, the baseline
    condition shall be calculated for the time period from 1980 to
    1996.
    2018 Iowa Acts ch. 1001, § 20.
    We do not see how declaring this section void would lead to lower
    water rates, more viewing enjoyment of the Raccoon River, or more
    swimming and kayaking opportunities in the Raccoon River for the
    plaintiffs’ members.
    The injunctive relief sought by the plaintiffs is also quite general.
    The plaintiffs ask us to enjoin the “State”—meaning the twenty-three
    different defendants in the lawsuit—to come up with “a mandatory
    remedial plan” that requires all grain and livestock producers “to
    implement nitrogen and phosphorus limitations in the Raccoon Valley
    watershed.” The plaintiffs admit that this plan can only be accomplished
    through legislation.    In fact, they argue they need not exhaust
    administrative remedies because what they seek can only be accomplished
    through legislation.   In their words: “[T]he agency Defendants lack
    authority to require nutrient limits for nitrogen and phosphorus from
    agricultural nonpoint sources.” Only the legislature can do this.
    But this leads immediately to the question of what that legislation
    would look like. There is no free lunch. According to the 2008 Water
    Quality Improvement Plan that is cited in the petition (and therefore part
    18
    of the materials we may consider),4 a 50% reduction in overall fertilizer
    application in the watershed—a dramatic change—would only produce a
    20% reduction in Raccoon River nitrate levels. This would not come close
    to meeting the 48.1% reduction in nitrate levels that the plaintiffs allege is
    needed for the Raccoon River to consistently have a nitrate level below
    10 mg/l and therefore meet the Class C drinking water standard without
    further treatment.
    Farmers use fertilizer for economic reasons, so this reduction in
    fertilizer application would affect yields and make Iowa farmers less
    competitive. The legislature might decide to charge the costs of efforts to
    reduce nitrogen and phosphorus runoff to the public rather than just to
    farmers. The legislature might decide that it is appropriate for all users of
    the Raccoon River watershed to bear these costs. This could lead to even
    higher out-of-pocket expenditures for the plaintiffs’ members.
    Notably, to the extent the issue is the need to remove nitrate
    pollution from drinking water in order to make it drinkable, the Des
    Moines Water Works (DMWW) is the party more directly affected and better
    positioned to bring a lawsuit.            It has already brought a lawsuit—
    unsuccessfully. See Bd. of Water Works Trs. of Des Moines v. Sac Cnty.
    Bd. of Supervisors, 
    890 N.W.2d 50
     (Iowa 2017); Bd. of Water Works Trs. of
    Des Moines v. Sac Cnty. Bd. of Supervisors, 
    2017 WL 1042072
     (N.D. Iowa
    Mar. 17, 2017).        There, DMWW sought money damages for costs of
    removing nitrates. Bd. of Water Works Trs. of Des Moines, 890 N.W.2d at
    52. DMWW “d[id] not suggest it would be cheaper for the [rural] drainage
    districts to remove nitrates from multiple locations than for DMWW to
    4See  King, 818 N.W.2d at 6 n.1 (holding that in ruling on a motion to dismiss for
    failure to state a claim, the court may consider documents referenced in the petition
    regardless of whether they have been attached).
    19
    remove nitrates from a single location.” Id. at 66. DMWW’s removal of
    nitrates for drinking water purposes costs about one cent per day per
    customer. Id. at 68.
    Also, it is not clear that even significant reductions in farmers’
    fertilizer use would actually bring about better kayaking, swimming, and
    viewing on the river.       According to the petition, cyanobacteria blooms,
    cyanotoxins, and microcystins are all increasing due to climate change.
    There is not enough here to demonstrate that a favorable outcome
    in this case is likely to redress the plaintiffs’ alleged reduced ability to
    kayak, swim, or enjoy views of the Raccoon River, or would save them
    money on drinking water.            The plaintiffs’ claims must therefore be
    dismissed for lack of standing.5
    Finally, we address the suggestion that the defendants conceded at
    oral argument that there would be standing for the plaintiffs’ declaratory
    judgment claim. Here is the actual exchange between a member of our
    court and defense counsel:
    QUESTION: So is what you’re saying, if -- if they didn’t
    ask for the injunctive relief or if we agreed with you that the
    injunctive relief was subject to the political question doctrine
    and then got rid of that, could the lawsuit proceed just on the
    declaratory relief that they’re requesting? ANSWER: I think
    it’s possible, yes. I mean -- and I’m just -- again, I’m accepting
    a lot of what-ifs here. Because the relief is the key, and the
    -- and the claims that they’ve asserted are the basis for the
    5We  found that the Sierra Club had standing to challenge a pipeline in Puntenney
    v. Iowa Utilities Board, 
    928 N.W.2d 829
    , 837–38 (Iowa 2019). But there was no
    speculative chain there. The injury came from one event—the construction and operation
    of a crude oil pipeline. Id. at 837. The issue was whether there was legal authority to
    build the pipeline. Id. at 832–33. The relief requested was to stop the pipeline. Id. A
    favorable decision on that point would have stopped the pipeline, at least until it had
    been built. Id. at 839–40. Contrast Puntenney with Citizens for Responsible Choices,
    where we held that the plaintiffs lacked standing to challenge the issuance of bonds
    because any injury would not result from the issuance of bonds per se, but from the
    project financed by the bonds. 
    686 N.W.2d at 475
    . The chain of causation, in other
    words, was too remote.
    20
    declaratory relief that they’re seeking, and so it’s kind of a
    naked request, if you will.
    And so -- and -- and I will have to concede that when
    we talk about redressability and causal connection to the
    injury, you know, it -- it -- the declaratory order, assuming
    that these are citizens that, you know, would be, under
    Justice McDonald’s analogy, beneficiaries of the trust, I -- I
    think I’d have to concede you could get to, if you wanted to, a
    declaratory order of some sort.
    But if we back into the overall framework of this lawsuit,
    it -- it doesn’t get them what they’re asking for, and it doesn’t
    remedy any of the alleged harms that they allege.
    (Emphasis added.)
    Several points should be noted. First, the question assumed that
    the injunctive relief claims would be subject to the political question
    doctrine and would not go forward. The issue was whether a declaratory
    judgment action alone could proceed.
    Second, although we do not find that defense counsel actually
    agreed the declaratory judgment part of the case could go forward, parties
    cannot bind us by an agreement that standing exists.              Standing is
    jurisdictional. Northbrook Residents Ass’n v. Iowa State Dep’t of Health
    Off. for Health Plan. & Dev., 
    298 N.W.2d 330
    , 331 (Iowa 1980); see also
    Godfrey, 
    752 N.W.2d at 417
     (“Generally, courts refuse to decide disputes
    presented in a lawsuit when the party asserting an issue is not properly
    situated to seek an adjudication.”). In Bechtel v. City of Des Moines, we
    observed that even with a declaratory judgment case “a justiciable
    controversy must exist; we will not decide an abstract question simply
    because litigants desire a decision on a point of law or fact.” 
    225 N.W.2d 326
    , 330 (Iowa 1975) (en banc).
    Third, even while conceding that “you could get to, if you wanted to,
    a declaratory order of some sort,” defense counsel added that “the relief is
    the key.” Thus, defense counsel pointed out that a declaratory order would
    21
    not remedy “any of the alleged harms that [the plaintiffs] allege.” We agree
    and therefore conclude that standing is absent in this case.
    C. Nonjusticiable Political Question.        We have described the
    doctrine as follows:
    A political question may be found when one or more of
    the following considerations is present:
    (1) a textually demonstrable constitutional commitment of the
    issue to a coordinate political department; (2) a lack of
    judicially discoverable and manageable standards for
    resolving the issue; (3) the impossibility of deciding without
    an initial policy determination of a kind clearly for nonjudicial
    discretion; (4) the impossibility of a court’s undertaking
    independent resolution without expressing a lack of the
    respect due coordinate branches of government; (5) an
    unusual need for unquestioning adherence to a political
    decision already made; or (6) the potentiality of
    embarrassment from multifarious pronouncements by
    various departments on one question.
    Besler, 954 N.W.2d at 435 (quoting King v. State, 
    818 N.W.2d 1
    , 17 (Iowa
    2012)).
    The plaintiffs urge us to reject the political question doctrine out of
    hand for two reasons. First, they claim it does not apply to state courts.
    This position rests on an incorrect reading of Freeman v. Grain Processing
    Corp., 
    848 N.W.2d 58
     (Iowa 2014). In Freeman, we concluded the political
    question doctrine did not apply to the facts of that case. 
    Id.
     at 93–94. But
    we acknowledged it had been applied in other cases.            Id. at 89, 92
    (discussing Des Moines Register & Tribune Co. v. Dwyer, 
    542 N.W.2d 493
    (Iowa 1996) (en banc), and State ex rel. Turner v. Scott, 
    269 N.W.2d 828
    (Iowa 1978) (en banc)); see also King, 818 N.W.2d at 21 n.17 (“There is a
    political question doctrine in Iowa as elsewhere.”).
    We applied the political question doctrine recently in State ex rel.
    Dickey v. Besler. 954 N.W.2d at 435–37. In Besler, we decided not to hear
    a lawsuit as to which of two officials (the Governor or the chief justice)
    22
    should have made an appointment when both had previously agreed to
    recognize the appointment made by one of them (the Governor). Id.
    Second, the plaintiffs insist that “constitutional claims are always
    justiciable.” Whatever the plaintiffs mean by this assertion, it is plainly
    too broad. Besler involved a constitutional claim, and we found the case
    nonjusticiable. In particular, the relator in Besler asserted that article V,
    section 15 of the Iowa Constitution required the chief justice rather than
    the Governor to make the appointment. Id. at 428–30.
    The plaintiffs rely on Luse v. Wray, 
    254 N.W.2d 324
     (Iowa 1977) (en
    banc). They are correct that in Luse, we held that claims brought by voters
    whose votes weren’t counted in a disputed state legislative election
    resolved by the legislature were justiciable.         
    Id.
     at 326–29.      We
    acknowledged that article III, section 7 provides, “Each house shall choose
    its own officers, and judge of the qualification, election, and return of its
    own members.” 
    Id. at 326
     (quoting Iowa Const. art. III, § 7). Yet the key
    point in Luse was that the voters had alleged substantial deprivations of
    their personal equal protection and due process rights when their votes
    weren’t counted. Id. at 328. As we stated,
    Iowa courts have power to adjudicate substantial claims of
    deprivation of federal or Iowa constitutional rights by the
    houses of the Iowa General Assembly in the exercise of the
    houses’ election contest powers under § 7 of Article III of the
    Iowa Constitution.
    Id. Just a year later, in State ex rel. Turner, we clarified the limited scope
    of the Luse holding when we decided that whether a successful legislative
    candidate had met the residency requirement set forth in article III,
    section 5 was a nonjusticiable political question. Turner, 
    269 N.W.2d at
    829–31. We emphasized that there had been no “showing of deprivation
    of substantial constitutional rights” as in Luse. 
    Id. at 832
    .
    23
    The plaintiffs seek to bring their claims under the umbrella of Luse
    rather than Turner by arguing they have made a showing of a deprivation
    of their own individual constitutional rights.               We are not persuaded.
    Granted, the plaintiffs have spliced into their petition references to due
    process (article I, section 9) and unenumerated rights (article I, section
    25).6 But the substantive basis for their claims remains the public trust
    doctrine. That doctrine, by definition, involves rights that belong to the
    public as a whole. Pleading “public rights plus article I, section 9” or
    “public rights plus article I, section 25” doesn’t alter the essential public-
    rights nature of the plaintiffs’ lawsuit. See Konrardy v. Vincent Angerer
    Tr., Dated March 27, 1998, 
    925 N.W.2d 620
    , 623 n.1 (Iowa 2019) (“We look
    to the substance of Konrardy’s and Burmeister’s claim, not the label they
    attach, to determine its legal significance.”); State v. Webster, 
    865 N.W.2d 223
    , 232 (Iowa 2015) (“[T]he substance of the claim, rather than its label,
    controls.”).
    Over a century ago, without using the term “political question,” we
    applied something akin to that doctrine when we decided that courts did
    not have jurisdiction to review determinations by county boards of
    supervisors not to form drainage districts. Denny v. Des Moines County,
    
    143 Iowa 466
    , 478, 
    121 N.W. 1066
    , 1071 (1909).                       We said that the
    sufficiency of a petition “in form or matter” to establish such a district was
    a proper subject for judicial review, but “the wisdom and practicability of
    a proposed drainage scheme” involved an exercise of “legislative authority”
    and district judges could only “determine judicial questions.” Id. at 475,
    121 N.W. at 1069–70. Therefore, even though the general assembly had
    6The due process clause provides that “no person shall be deprived of life, liberty,
    or property, without due process of law.” Iowa Const. art. I, § 9. The unenumerated
    rights clause provides, “This enumeration of rights shall not be construed to impair or
    deny others, retained by the people.” Id. § 25.
    24
    conferred jurisdiction on district courts to consider such appeals, we
    affirmed the district court’s dismissal of the action for want of jurisdiction.
    Id. at 471, 121 N.W. at 1067, 1071. We said,
    In view of the express provision of our state Constitution
    that the powers of the government shall be divided into three
    separate departments, the legislative, the executive, and the
    judicial, and that no person charged with the exercise of
    powers properly belonging to one of these departments shall
    exercise any function appertaining to either of the others,
    except as in the Constitution expressly directed or permitted
    (Const. art. 3, § 1), it must be conceded that, if the authority
    vested in the board of supervisors is in its nature legislative,
    and not judicial, then the district court, which is only vested
    with judicial power (Const. art. 5, §§ 1, 6), cannot by statute
    be authorized to exercise such authority.
    Id. at 471, 121 N.W. at 1068. In other words, the pros and cons of a
    drainage district ultimately required the exercise of “legislative discretion,”
    as opposed to being a question that could be resolved upon “issuable facts,
    capable of judicial determination.” Id. at 472, 121 N.W. at 1069.
    More recently, we have approved of the six-part test quoted above to
    determine whether a case presents a nonjusticiable political question. See
    Besler, 954 N.W.2d at 435; King, 818 N.W.2d at 17; Dwyer, 542 N.W.2d at
    495, Turner, 
    269 N.W.2d at 831
    . The test is drawn from a famous United
    States Supreme Court decision. See Baker v. Carr, 
    369 U.S. 186
    , 210, 
    82 S. Ct. 691
    , 706 (1962).
    As we have noted, the plaintiffs here seek to expand the traditional
    Iowa public trust doctrine. Historically, this doctrine has been applied by
    our courts in cases        seeking to remove private obstructions or
    interferences. These types of disputes are susceptible to judicial resolution
    using principles of property law. The plaintiffs allege, however, that the
    public trust doctrine “broadly protects the public’s use of navigable
    waters.” In other words, the plaintiffs argue that the doctrine imposes a
    25
    duty on the State to pass laws that regulate those waters in the best
    interests of the public.
    Under those circumstances, we perceive “a lack of judicially
    discoverable and manageable standards.”          Besler, 954 N.W.2d at 435
    (quoting King, 818 N.W.2d at 17). In our view, stating that the legislature
    must “broadly protect[] the public’s use of navigable waters” provides no
    meaningful standard at all. Different uses matter in different degrees to
    different people. How does one balance farming against swimming and
    kayaking? How should additional costs for farming be weighed against
    additional costs for drinking water?        Even if courts were capable of
    deciding the correct outcomes, they would then have to decide the best
    ways to get there.     Should incentives be used?         What about taxes?
    Command-and-control policies? In sum, these matters are not “claims of
    legal right, resolvable according to legal principles, [but] political questions
    that must find their resolution elsewhere.” Rucho v. Common Cause, ___

    , 2494 (2019).
    The suggestion is made that this court could simply tell our
    legislature to pass laws that would bring nitrate levels in the Raccoon River
    consistently below 10 mg/l. That’s a specific outcome. But there are no
    judicially discoverable and manageable standards to aid a court in
    deciding whether that outcome is better than any other outcome. In Rucho
    v. Common Cause, for example, the plaintiffs and their amici proposed a
    variety of specific antigerrymandering rules.       But how was a court to
    determine one was preferable to another?
    Moreover, this case presents a much higher degree of complexity
    than Rucho because passing laws that will ultimately alter nitrogen and
    phosphorus content is far more challenging than adopting a redistricting
    map. As already noted, even if a court could decide that the public trust
    26
    doctrine mandated a particular outcome, the question would immediately
    arise how to get there.
    In that regard, it seems impossible for a court to grant meaningful
    relief “without expressing a lack of the respect due coordinate branches of
    government.” See Besler, 954 N.W.2d at 435 (quoting King, 818 N.W.2d
    at 17). Normally, in equity proceedings, courts issue orders that can be
    read and then implemented. This preserves the independence of other
    branches of government by limiting the degree and duration of judicial
    supervision. Here, by contrast, the plaintiffs ask for a judicial directive to
    the legislature “to adopt and implement a mandatory remedial plan to
    restore and protect public use that requires agricultural nonpoint sources
    and CAFO’s [confined animal feeding operations] to implement nitrogen
    and phosphorus limitations in the Raccoon River watershed.” Not only
    would this directive be aimed at the legislature, which in itself raises
    separation of powers concerns, but an indefinite number of policy choices
    that would then need to be made. Inevitably, the legislature would have
    to send its emissaries to 500 Mulberry Street or 1111 East Court Avenue
    in Des Moines.    Proposals would be submitted to the judiciary on an
    ongoing basis for our approval or disapproval.       In effect, the judiciary
    would be exercising a veto power over the legislature. At this point, we
    would cease to be a coequal branch of government.           Instead, we’d be
    asserting superiority.
    Another consideration is that the political branches in Iowa have
    made “an initial policy determination” to go in a different direction. Id. at
    435 (quoting King, 818 N.W.2d at 17).          As the petition alleges, the
    voluntary Iowa Nutrient Reduction Strategy that they seek to overturn has
    been enshrined in legislation enacted in 2013 and 2018. See 2018 Iowa
    Acts ch. 1001, § 20; 2013 Iowa Acts ch. 132, § 60. The federal EPA also
    27
    supports this approach. To quote the 2011 Stoner Memorandum cited in
    the petition,
    EPA’s focus for nonpoint runoff of nitrogen and
    phosphorus pollution is on promoting proven land
    stewardship practices that improve water quality.            EPA
    recognizes that the best approaches will entail States, federal
    agencies, conservation districts, private landowners and other
    stakeholders working collaboratively to develop watershed-
    scale plans that target the most effective practices to the acres
    that need it most.

    [https://perma.cc/Z5Q5-U7FK].                  The plaintiffs believe the existence of
    this longstanding, basic policy determination should not deter us because
    it provides a frame of reference for what the courts should not do. We
    think this misconstrues the third political-question factor. The third factor
    focuses not on timing, but on priority.                       Is there a required policy
    determination that is more appropriate for another branch that sets the
    stage for everything else? If so, courts should not get involved. Kanuk ex
    rel. Kanuk v. State, Dep’t of Nat. Res., 
    335 P.3d 1088
    , 1098 (Alaska 2014)
    (“The underlying policy choices are not ours to make in the first instance.”).
    We recognize that this case may not involve a paradigm of “a
    textually demonstrable constitutional commitment of the issue to a
    coordinate political department.” Besler, 954 N.W.2d at 435 (quoting King,
    818 N.W.2d at 17). But there should be no doubt that the plaintiffs are
    seeking additional state funding. One paragraph of the petition alleges
    inadequate funding of the DNR. Article III, section 24 provides, “No money
    shall be drawn from the treasury but in consequence of appropriations
    made by law.” This case, if it proceeds, would put the judiciary in the
    28
    position of commandeering additional state funding for intensive
    regulation of nitrogen and phosphorus in yet-to-be-determined ways.
    Other cases support the conclusion that environmental public trust
    litigation is a nonjusticiable political question. In Aji P. ex rel. Piper v.
    State, the Washington Court of Appeals recently affirmed the dismissal on
    political question grounds of a lawsuit seeking to use the public trust
    doctrine to achieve the regulation of greenhouse gas emissions. 
    480 P.3d 438
    , 447–49 (Wash. Ct. App. 2021); see also Kanuk, 335 P.3d at 1090–91
    (finding claims seeking specific relief based on the public trust doctrine to
    be barred by the political question doctrine and that other, more general
    claims should have been dismissed on prudential grounds); Butler ex rel.
    Peshlakai v. Brewer, 
    2013 WL 1091209
    , at *7 (Ariz. Ct. App. Mar. 13, 2013)
    (finding public trust claims nonjusticiable and noting “we would be
    weaving ‘a jurisprudence out of air’ to hold that the atmosphere is
    protected by the Doctrine and that state inaction is a breach of trust
    merely because it violates the Doctrine without pointing to a specific
    constitutional provision or other law that has been violated.”); Sanders-
    Reed ex rel. Sanders-Reed v. Martinez, 
    350 P.3d 1221
    , 1227 (N.M. App.
    2015) (“Separation of powers principles would be violated by adhering to
    Plaintiffs’ request for a judicial decision that independently ignores and
    supplants the procedures established under the Air Quality Control
    Act. . . . We conclude that the courts cannot independently intervene to
    impose a common law public trust duty upon the State to regulate
    greenhouse gases in the atmosphere.”).
    The plaintiffs invoke Environmental Law Foundation v. State Water
    Resources Control Board, 
    237 Cal. Rptr. 3d 393
     (Ct. App. 2018), but we
    think the case is distinguishable. The scope of the court’s ruling in that
    case was “extraordinarily narrow.” Id. at 396. The only issue was whether
    29
    a California agency and a county had to consider the potential harm from
    groundwater extraction on a navigable river before issuing well permits.
    Id. Pumping of groundwater has an effect on surface flows. Id. at 397.
    The court held that the public trust doctrine applied to such removals of
    nonnavigable water that had an adverse effect on navigable water. Id. at
    402. Significantly, the case involved a single question of administrative
    law, and the California version of the public trust doctrine “is expansive.”
    Id. at 400. But our present case does not involve a discrete attempt to
    modify an administrative process to insure that the consideration of
    arguments against diverting water that would otherwise go into a public
    trust navigable river. Instead, it seeks to order the legislature to enact a
    new set of environmental laws that balance the competing interests of
    stakeholders in different ways than before.
    Finally, we believe we should draw lessons from Oregon’s
    experience. In 2011, two young Oregonians brought a suit against the
    State of Oregon under the public trust doctrine, seeking to protect its
    natural resources from the effects of greenhouse gas emissions. Chernaik
    v. Brown, 
    475 P.3d 68
    , 71–72 (Or. 2020). Specifically, the plaintiffs sought
    a declaratory judgment and an injunction directing the state to implement
    a carbon reduction plan under court supervision. 
    Id.
     Initially, the trial
    court dismissed the plaintiffs’ claims partly because they presented
    political questions. Id. at 72. The Oregon Court of Appeals reversed and
    remanded. Id. Eventually, after years of litigation, the case reached the
    Oregon Supreme Court, which ruled that the plaintiffs were not entitled to
    any relief except for a symbolic declaration that the public trust doctrine
    applies to navigable waters and submerged and submersible lands. Id. at
    82. That was the anticlimactic end to nearly a decade of litigation.
    30
    We can do better. Where the plaintiffs have put forth claims that we
    cannot meaningfully resolve as a court using accepted methods of judicial
    decisionmaking, we should invoke the political question doctrine. We do
    so here and leave this dispute where it stands at present: with the
    branches of our government whose duty it is to represent the public. In
    the end, we believe it would exceed our institutional role to “hold the State
    accountable to the public.” Those words, used by the plaintiffs to describe
    what they ask of us, go beyond the accepted role of courts and would
    entangle us in overseeing the political branches of government.7
    IV. Conclusion.
    For the foregoing reasons, we reverse the district court’s order and
    remand with instructions to dismiss this case based on lack of standing
    and nonjusticiability.
    REVERSED AND REMANDED.

    7Lest  we be misunderstood, we agree that the petition describes a real
    environmental problem, both in Iowa and nationally. In their petition, the plaintiffs
    discuss the hypoxic zone in the Gulf of Mexico and the 2008 Gulf Hypoxia Plan. As
    further noted in the petition, the EPA declined in 2011 to take national action and a
    lawsuit seeking to reverse that decision failed. See Gulf Action Network v. Jackson, 
    224 F. Supp. 3d 470
    , 474–75 (E.D. La. 2016). But we are a court, and we would be stepping
    outside our role to take on this matter as presented to us by these plaintiffs.

    #19–1644, Iowa Citizens for Cmty. Improvement v. State
    APPEL, Justice (dissenting).
    In Lujan v. Defenders of Wildlife, Justice Harry Blackmun wrote, “I
    cannot join the Court on what amounts to a slash-and-burn expedition
    through the law of environmental standing.” 
    504 U.S. 555
    , 606, 
    112 S. Ct. 2130
    , 2160 (1992) (Blackmun, J., dissenting). In short, Lujan is precisely
    the kind of case where we should heed recent admonitions to not simply
    adopt federal caselaw in a top-down constitutional world. See Jeffrey S.
    Sutton, 51 Imperfect Solutions: States and the Making of American
    Constitutional Law 20 (2018). The majority, however, chooses to bring
    what Justice Blackmun called “slash-and-burn” to Iowa when reviewing a
    motion to dismiss a suit alleging injury in violation of the public trust
    doctrine.
    I dissent. For starters, I would follow the approach of our state court
    colleagues in Colorado, Connecticut, Hawaii, Nevada, Oregon, and
    Washington8 and refuse to erect the barriers to access to the courts which
    were developed in a conference room in Washington, D.C., over the bitter
    protest of a minority of the Supreme Court. See Wyatt Sassman, A Survey
    of Constitutional Standing in State Courts, 8 Ky. J. Equine, Agric., & Nat’l
    Res. L. 349, 349 (2016) (noting that only a minority of states adopt the test
    adopted in Lujan). In particular, I would refuse to allow a handwringing
    application of standing doctrine to throttle environmental litigation in a
    motion to dismiss an action for declaratory and injunctive relief based on

    “redressability” requirements.

    112 S. Ct. at 2136
    .
    I have already canvassed the law of standing in my dissent in Dickey
    v. Iowa Ethics & Campaign Disclosure Board. 
    943 N.W.2d 34
    , 42–57 (Iowa
    2020) (Appel, J., dissenting). By way of brief summary, the federal courts
    are restricted by the “case or controversy” requirements of Article III of the
    United States Constitution. Id. at 42. The limitations in Article III are
    based, in part, on considerations of federalism; namely, keeping federal
    courts out of state business. See id. But in this case, of course, there are
    no federalism considerations. We are a state court dealing with the state’s
    business. And our state constitutional framers deliberately omitted the
    language of Article III from the state constitution. See id. at 43. Unlike
    the federal courts of limited jurisdiction, general jurisdiction state courts
    were designed to be problem-solving courts with sufficient judicial power
    to effectively resolve a wide range of disputes brought to the local
    courthouse by citizens. Id. at 42.
    As a result, in Iowa, we have correctly held that “the federal test for
    standing is based in part upon constitutional strictures and prudential
    considerations while our rule on standing is self-imposed.” Alons v. Iowa
    Dist. Ct., 
    698 N.W.2d 858
    , 869 (Iowa 2005). There is no requirement for
    us to blindly follow federal precedent in standing or any other area of law.
    And I have no interest in closing down access to the courts with the
    “gotcha” applications of “redressability” and “causation” announced in
    Lujan and inconsistently applied thereafter, particularly when the newly
    discovered elements of standing are astonishingly applied at the motion to
    dismiss stage of litigation to dismiss cases involving important state
    constitutional issues. See, e.g., William A. Fletcher, Standing: Who Can
    Sue to Enforce a Legal Duty?, 
    65 Ala. L. Rev. 277
    , 286–87 (2013) (“The
    33
    environmental [standing] cases also respond to the Court’s perception of
    political reality. . . . [The Supreme Court] is narrowly construing statutes
    with whose policies it disagrees, using a standing doctrine that it has
    developed for this purpose.”); Oliver A. Houck, Arbitrary and Capricious:
    The Dark Canon of the United States Supreme Court in Environmental Law,
    33 Geo. Env’t L. Rev. 51, 70 (describing Lujan as “The Weaponization of
    Standing”); Cass R. Sunstein, Standing and the Privitization of Public Law,
    
    88 Colum. L. Rev. 1432
    , 1480 (1988) (stating that the court’s standing
    doctrine arises not from “restraint in the abstract but instead from hostility
    to suits brought by beneficiaries of regulatory programs to ensure fidelity
    to statute”).
    Although we have cited Lujan in a few cases on occasion, up until
    now, we have not adopted its new and innovative elements of “causation”
    and “redressability” into our standing doctrine. In Alons v. Iowa District
    Court, we cited Lujan for the traditional “injury in fact” federal standing
    requirement. 
    698 N.W.2d at
    867–68. In Sanchez v. State, we cited Lujan
    for the traditional requirement of “injury in fact” again but the newly
    fashioned “causation” and “redressability” additions of Lujan were not part
    of the holding of the Iowa case.      
    692 N.W.2d 812
    , 821 (Iowa 2005).
    Notably, no party in these cases cited Lujan in their briefs, let alone urged
    adoption of the “causation” or “redressability” discoveries of the case.
    Indeed, there is no Iowa case citing Lujan where the question of whether
    we should import into Iowa law its newly developed standing criteria on
    “causation” or “redressability.” But once a federal case is casually cut and
    pasted into the Iowa law books in an uncontested setting, it has a
    tendency, particularly if the federal case is rights restricting, to germinate
    into accidental precedent.
    34
    Here is the bottom line. We should not adopt the access to the
    courts restrictions of Lujan. We don’t need them. Our public trust cases
    have adhered to traditional standing doctrine. In Bushby v. Washington
    County Conservation Board, the court considered standing in a public
    trust and environment claim. 
    654 N.W.2d 494
    , 496–97 (Iowa 2002). The
    Bushby court required the plaintiffs to show the traditional elements of
    “(1) a specific, personal, and legal interest in the litigation, and (2) injury.”
    
    Id. at 496
     (quoting Rieff v. Evans, 
    630 N.W.2d 278
    , 284 (Iowa 2001)
    (en banc)). More recently, in Puntenney v. Iowa Utilities Board, we held
    that a nonprofit environmental organization had standing to challenge the
    approval of an oil pipeline and the use of eminent domain under the
    Bushby standard. 
    928 N.W.2d 829
    , 837 (Iowa 2019). No mention of Lujan.
    We should follow the Bushby standard here.
    In any event, at the pleading stage, it is clear that the plaintiffs have
    alleged causation and redressability sufficient to survive a motion to
    dismiss even under Lujan. The plaintiffs attack the failure of the state to
    regulate agricultural nitrogen and phosphorus that enters the Raccoon
    River and substantially impairs the waterway. This allegation certainly
    satisfies the innovative “causation” element of Lujan. Further, as for the
    newly discovered “redressability requirement” that the State seeks to
    import into state law, the plaintiffs do not need to show that the requested
    relief will solve the problem completely but only that it will do some good.
    Pub. Int. Rsch. Grp. v. Powell Duffryn Terminals Inc., 
    913 F.2d 64
    , 73 (3d
    Cir. 1990). And, though it apparently may not matter, the State concedes
    the presence of injury in fact and the traditional elements of standing.
    I now turn to the majority’s discussion of the scope of the public
    trust doctrine. The majority provides a couple of pages that the average
    reader would likely conclude advance a narrow construction of the public
    35
    trust doctrine. The issue was not briefed by the parties and is not before
    the court. One could respond, I suppose, by noting the very generous
    language in State v. Sorenson, 
    436 N.W.2d 358
    , 363 (Iowa 1989), which
    stated that although we do not necessarily subscribe to the broad
    application of the doctrine, “the public trust doctrine . . . applies broadly
    to the public’s use of property, such as waterways, without ironclad
    parameters on the types of uses to be protected.” (Emphasis omitted.)
    I do not join the majority’s essay on the question or any of its narrow
    pronouncements oddly made in a case where a party has conceded, for
    purposes of a motion to dismiss, that the scope of the public trust doctrine
    is not at issue. I do note, however, from my review of cases that the public
    trust doctrine is not the proverbial legal fly frozen in amber. See Marks v.
    Whitney, 
    491 P.2d 374
    , 380 (Cal. 1971) (en banc) (“In administering the
    trust the state is not burdened with an outmoded classification favoring
    one mode of utilization over another.”); In re Water Use Permit Applications,
    
    9 P.3d 409
    , 450 (Haw. 2000) (declaring that purposes or uses of the public
    trust doctrine have “evolved over time”); Matthews v. Bay Head
    Improvement Ass’n, 
    471 A.2d 355
    , 365 (N.J. 1984) (declaring public trust
    doctrine is not “ ‘fixed or static,’ but one to ‘be molded and extended to
    meet changing conditions and needs of the public it was created to
    benefit.’ ” (quoting Borough of Neptune City v. Borough of Avon-By-The-Sea,
    
    294 A.2d 47
    , 55 (N.J. 1972))). And, beginning with the seminal article of
    Professor Sax in the Michigan Law Review fifty years ago, there is now a
    rich literature on the public trust doctrine that collect cases and provide
    rich insight into the questions of content and scope of the doctrine in the
    modern age. See Joseph Sax, The Public Trust Doctrine in Natural Resource
    Law: Effective Judicial Intervention, 
    68 Mich. L. Rev. 471
     (1970).       See
    generally Michael C. Blumm & Mary Christina Wood, “No Ordinary
    36
    Lawsuit,”: Climate Change, Due Process, and the Public Trust Doctrine, 
    67 Am. U. L. Rev. 1
     (2017); Harrison C. Dunning, The Public Trust: A
    Fundamental Doctrine of American Property Law, 19 Env’t L. 515 (1989);
    Gerald Torres & Nathan Bellinger, The Public Trust Doctrine: The Law’s
    DNA, 4 Wake Forest J.L. & Pol’y 281 (2014). But conservative scholars
    and others want to petrify or at least embalm the public trust doctrine.
    See James L. Huffman, Why Liberating the Public Trust Doctrine is Bad for
    the Public, 45 Env’t Law 337 (2015).
    Ordinarily, courts do not develop doctrine on uncontested issues,
    and ordinarily I would not opine on them. However, if pushed into a corner
    by a majority that insists on proceeding to develop the contours of the
    public trust doctrine notwithstanding the State’s concession, I would
    declare that the public trust doctrine applies to pollution of navigable
    waterways in a fashion that prevents or significantly impairs recreational
    activities and the use of water for drinking purposes. See Nat’l Audubon
    Soc’y v. Superior Ct., 
    658 P.2d 709
    , 712 (Cal. 1983) (applying public trust
    doctrine in environmental setting); In re Water Use Permit Applications, 
    9 P.3d at 447
     (holding that public trust applies to ground water and surface
    water); Lamprey v. Metcalf, 
    53 N.W. 1139
    , 1143 (Minn. 1893) (noting that
    public trust doctrine applies to use of waterways “and other public
    purposes which cannot now be enumerated or even anticipated”); Ralph
    W. Johnson, Water Pollution and the Public Trust Doctrine, 19 Env’t Law
    485, 493–98 (1989).
    In addition to these observations, I join in the dissent of Justice
    Oxley regarding the premature nature of the majority’s decision. I also
    incorporate my dissent in State ex rel. Dickey v. Besler, which is dispositive
    on the political question issue posed in this case. 
    954 N.W.2d 425
    , 439–
    49 (Iowa 2021) (Appel, J., dissenting).
    For the above reasons, I dissent.

    The public trust doctrine is of long standing. The “doctrine is said
    to be traceable to the work of Emperor Justinian, based on the notion that
    the public possesses inviolable rights to certain natural resources.” State
    v. Sorensen, 
    436 N.W.2d 358
    , 361 (Iowa 1989). “The doctrine was adopted
    into the English common law and embraced by nineteenth century
    American jurists.”      
    Id.
       Under the doctrine, “the interest of state
    government in public trust land is, in a sense, only that of a steward.”

    This stewardship is “a burden, rather than a benefit.”

    , 813 (Iowa 2000) (en banc).             As the majority
    correctly notes, the doctrine has been limited to protecting the public’s
    access to public waters and to preventing the state from alienating lands
    held in the public trust. See Larman v. State, 
    552 N.W.2d 158
    , 161 (Iowa
    1996). It is not disputed that private citizens have standing to sue for
    violations of the public trust doctrine, as traditionally understood. See,
    e.g., Bushby v. Wash. Cnty. Conservation Bd., 
    654 N.W.2d 494
    , 497 (Iowa
    2002) (holding private citizens had standing under the public trust
    doctrine and resolving the case on the merits); Witke v. State Conservation
    Comm’n, 
    244 Iowa 261
    , 271–72, 
    56 N.W.2d 582
    , 588–89 (1953) (reaching
    merits of the claim and stating “the state may not restrict or charge for the
    use of the waters of navigable streams or lakes, and an attempt on its part
    to do so is a deprivation of the citizen of his property without due process
    of law, and without compensation, and so in violation of Sections 9 and 18
    of Article I of the Constitution of Iowa”).
    In this case, the plaintiffs seek to channel the traditional
    understanding of the public trust doctrine in a new direction. They claim
    38
    the doctrine imposes upon the State, as steward of lands held in the public
    trust, an affirmative obligation to protect the public use of navigable waters
    and to prevent the substantial impairment of navigable waters.           They
    further claim the State has violated this affirmative duty by allowing
    nitrogen and phosphorous discharges from agricultural sources to impair
    the recreational and drinking water uses of the meandered section of the
    Raccoon River. The plaintiffs claim the State’s failure to act under these
    circumstances constitutes a violation of the public trust doctrine and
    constitutes a taking of their constitutionally-protected property interest in
    public lands. See, e.g., Witke, 244 Iowa at 272, 
    56 N.W.2d at 589
     (holding
    the state’s restriction of access to navigable streams or lakes “is a
    deprivation of the citizen of his property without due process of law”).
    Whether the public trust doctrine can be channeled in this new
    direction is not properly before this court. In navigating this case, the
    State, for whatever reason, chose to not challenge the merits of the
    plaintiffs’ claims in the district court or on appeal. The Solicitor General
    made this clear during oral argument, stating, “Let me be clear that—that
    these issues about the public trust doctrine are specifically not before the
    court right now.” Thus, for the purposes of resolving this appeal involving
    only the standing doctrine and the political questions doctrine, we must
    assume the public trust doctrine is as broad as the plaintiffs claim.
    The State’s decision to forego any substantive challenge to the merits
    of the plaintiffs’ claims, in my view, largely resolves this appeal. If private
    citizens have standing to sue for violations of the public trust doctrine as
    traditionally understood, see Witke, 244 Iowa at 272, 
    56 N.W.2d at 589
    , it
    stands to reason the same private citizens have standing to sue for
    violations of the public trust doctrine as they seek to expand it.          At
    minimum, the plaintiffs have standing to pursue declaratory relief. The
    39
    Solicitor General conceded this during oral argument: “I will have to
    concede that when we talk about redressability and causal connection to
    the injury . . . I think I’d have to concede you could get to, if you wanted
    to, a declaratory order of some sort . . . .”   In the procedural posture
    presented, on this record, I agree with the Solicitor General that, at
    minimum, the plaintiffs have sufficient standing to pursue some form of
    limited relief.
    The majority raises a host of legitimate concerns regarding the
    constitutionality, feasibility, and efficacy of potential remedies. I share
    those concerns. And, perhaps, those concerns militate against expansion
    of the public trust doctrine. But, for now, this case is at the headwaters.
    The State has conceded, for now, the public trust doctrine goes as far as
    the plaintiffs contend. In the procedural posture presented, the plaintiffs
    have thus asserted a cognizable legal claim. “[A] plaintiff . . . has what we
    have come to call ‘standing,’ whenever he has a legally cognizable cause of
    action, regardless of whether he can show a separate, stand-alone factual
    injury.” Sierra v. City of Hallandale Beach, 
    996 F.3d 1110
    , 1115 (11th Cir.
    2021) (Newsom, J., concurring); id. at 1131 (“The question whether a
    plaintiff has ‘standing’ really just boils down to the question of whether he
    has a cause of action—whether his legal rights have been infringed and
    whether the positive law authorizes him to sue for that infringement.”).
    The State has conceded, for now, the plaintiffs at least have standing to
    pursue some limited relief under an expanded public trust doctrine. What
    relief exactly—and the constitutionality, feasibility, and efficacy of that
    relief—are best worked out in the district court on a better record and with
    fuller briefing.
    40
    For these reasons, I would affirm the judgment of the district court,
    remand this matter, and allow the case to continue downstream.            I
    respectfully dissent.

    OXLEY, Justice, (dissenting).
    Ours is an adversarial system, and the court’s role is to decide the
    issues as presented by the parties.9 Yet the State has put us between the
    proverbial rock and a hard place by insisting it is not challenging the scope
    of the public trust doctrine, its imposition of affirmative obligations on the
    State, or its constitutional underpinnings. Protestations notwithstanding,
    the majority necessarily decides those issues in concluding the plaintiffs
    lack standing and raise only nonjusticiable political questions. While I
    share the majority’s doubt as to how far the plaintiffs can ride their public
    trust doctrine horse, expediency is not a basis for dismissing cases. Given
    the posture of this appeal, I respectfully dissent.
    The plaintiffs assert that the constitutionally-based public trust
    doctrine protects their right to use the Raccoon River for recreation and
    drinking water purposes; those uses are being harmed by pollution in the
    river, specifically harmful levels of nitrates that exceed acceptable levels
    identified by legislative and executive bodies; the State has an affirmative
    obligation to protect the plaintiffs’ rights against that pollution; and the
    State has failed to meet those affirmative obligations where it relies only
    on voluntary compliance efforts to convince agricultural nonpoint sources
    to reduce the amounts of nitrogen and phosphorus used as fertilizer that
    make their way into the river. The plaintiffs seek a declaration of their
    constitutional rights, the State’s obligations to protect those rights, and
    whether the State has breached those obligations. The plaintiffs also seek
    9See     State v. Struve, 
    956 N.W.2d 90
    , 99 n.2 (Iowa 2021) (“[O]ur system ‘is designed
    around the premise that [parties represented by competent counsel] know what is best
    for them, and are responsible for advancing the facts and argument entitling them to
    relief.’ ” (alteration in original) (quoting United States v. Sineneng-Smith, 590 U.S. ___, ___,
    
    140 S. Ct. 1575
    , 1579 (2020))).
    42
    a declaration that the State’s adoption of the voluntary strategy as the
    official policy of the State for addressing nitrate levels in navigable waters
    violates the State’s obligations under the doctrine and an injunction
    requiring state officials to take action to reduce nitrate levels.
    Despite its origins related to navigation and commerce, we have
    expanded the public trust doctrine “to safeguard the public’s use of
    navigable waters for purely recreational and non-pecuniary purposes.”
    Robert’s River Rides, Inc. v. Steamboat Dev. Corp., 
    520 N.W.2d 294
    , 299
    (Iowa 1994), abrogated on other grounds by Barreca v. Nickolas, 
    683 N.W.2d 111
    , 121 (Iowa 2004); see also State v. Pettijohn, 
    899 N.W.2d 1
    , 35
    (Iowa 2017) (describing recreational use of navigable waters as a
    “ ‘paramount’ right” under the public trust doctrine); McCauley v. Salmon,
    
    234 Iowa 1020
    , 1022, 
    14 N.W.2d 715
    , 716 (1944) (“The right of the public
    to navigate the water is paramount. This includes the right of fishing,
    boating, skating and other sports.”        (citations omitted)).   And we have
    allowed private citizens to assert rights under the doctrine.         See, e.g.,
    Bushby v. Wash. Cnty. Conservation Bd., 
    654 N.W.2d 494
    , 496–97 (Iowa
    2002); Witke v. State Conservation Comm’n, 
    244 Iowa 261
    , 263–64, 
    56 N.W.2d 582
    , 584–85 (1953).        Here, the plaintiffs seek to extend the
    doctrine to impose an obligation on the State to protect navigable waters
    from effective alienation through pollution. And, critical to our resolution
    of the specific issues before us, the State accepts the plaintiffs’ position as
    an acceptable extension of the public trust doctrine.
    The majority makes a principled argument that the public trust
    doctrine does not impose such affirmative obligations on the State and
    that even if it did, the doctrine does not provide private parties with a cause
    of action to enforce any such affirmative obligations. The problem is that
    the parties do not address the scope of the public trust doctrine or whether
    43
    it provides a cause of action for the plaintiffs. Indeed, the State insists its
    position assumes the doctrine applies as broadly as the plaintiffs assert.
    As Justice McDonald points out, the Solicitor General reinforced its
    position during oral argument. The State, as part of its litigation strategy,
    made a decision to not challenge the merits of the public trust doctrine as
    articulated by the plaintiffs.    Thus, for the purposes of resolving this
    motion to dismiss, we must assume the public trust doctrine is as broad
    as the plaintiffs claim.
    The majority refuses to do that. That the majority has decided the
    merits of the public trust issue is best seen in its discussion of the political
    question doctrine, explaining it is “not persuaded” that the plaintiffs have
    made a showing of a deprivation of their own individual constitutional
    rights, thereby distinguishing Luse v. Wray, 
    254 N.W.2d 324
    , 327–28 (Iowa
    1977) (en banc). The majority must do so because “the judiciary’s power
    to interpret the constitution and to review the constitutionality of the laws
    and acts of the legislature does not offend [political question] principles.”
    King v. State, 
    818 N.W.2d 1
    , 17 (Iowa 2012) (citing Luse, 
    254 N.W.2d at
    327–28 and Marbury v. Madison, 5 U.S. (1 Cranch) 137, 177–78 (1803)).
    Rather, “it is a matter for the judiciary to pass upon the constitutionality
    of the official and specific acts of the other departments of government.”
    Luse, 
    254 N.W.2d at 327
     (quoting 16 C.J.S. Constitutional Law § 144, at
    688). This principle holds true in the context of asserted violations of the
    public trust doctrine. See, e.g., Kanuk ex rel. Kanuk v. State, Dep’t of Nat.
    Res., 
    335 P.3d 1088
    , 1099 (Alaska 2014) (explaining that “[t]he Baker

    only after first determining that the plaintiffs failed to state claims for relief
    under the education clauses of the Iowa Constitution. See 818 N.W.2d at

    litigation that resulted in the less-than-satisfying “symbolic” declaration of the extent of
    the public trust doctrine’s scope, see Chernaik v. Brown, 
    475 P.3d 68
    , 71–72 (Or. 2020),
    not only places the majority in the adversary’s role but also ignores critical distinctions
    between the greenhouse gas emission cases attempting to extend the public trust doctrine
    to cover the atmosphere cited by the majority and the already-established protections for
    recreational use of navigable water involved here. Cf. Kanuk, 335 P.3d at 1103
    (distinguishing between requests to extend public trust doctrine to cover atmosphere as
    a natural resource and claims premised on detrimental impacts on “already-recognized
    public trust resources such as water, shorelines, wildlife, and fish”). Despite the
    majority’s apparent skepticism of the plaintiffs’ position, we must also accept the detailed
    pleaded facts as true for purposes of reviewing the defendants’ motion to dismiss. See
    Hawkeye Foodservice Distrib., Inc. v. Iowa Educators Corp., 
    812 N.W.2d 600
    , 604 (Iowa
    2012).
    45
    constitutional claims failed as a matter of law, which allowed us to address
    the contours of the constitutional claims on appeal. Id. at 11.
    Faced with this dilemma, the majority effectively holds the plaintiffs
    lack a private cause of action because “the substantive basis for their
    claims remains the public rights[11] doctrine,” which “by definition, involves
    rights that belong to the public as a whole.”                  Despite no briefing or
    argument by the parties, the majority has eviscerated any claim that the
    public trust doctrine provides a private cause of action for private citizens.
    And if holding no cause of action exists is not addressing the merits of the
    plaintiffs’ claims, it is hard to imagine what would be.
    We have never held that the public trust doctrine cannot serve as
    the basis of individual constitutional rights. We have, however, held that
    plaintiffs seeking to extend the public trust doctrine to natural resources
    other than navigable waters had standing to challenge a conservation
    board’s plans to cut down trees in a public park, ultimately concluding
    nonetheless that the doctrine did not extend to management of forested
    areas. See Bushby, 
    654 N.W.2d at
    496–98.
    In White Bear Lake Restoration Ass’n ex rel. State v. Minnesota
    Department of Natural Resources, the Minnesota Supreme Court started
    by addressing the scope of its public trust doctrine, concluding it was “not
    inclined to extend the public trust doctrine” to cover the plaintiffs’ claims
    before then discussing the heavy regulation of the field of public water as
    supporting the decision not to extend the common law absent a compelling
    reason to do so. See 
    946 N.W.2d 373
    , 386–87 (Minn. 2020). Given the
    11The   majority’s reference to the “public rights doctrine,” something different than
    the public trust doctrine, does not make its analysis any less dependent on the merits of
    the plaintiffs’ claim. A doctrine not discussed by the parties, we have never used the
    public rights doctrine to deny a citizen the right to hold the state to its obligations under
    the public trust doctrine not to alienate the public’s rights to access and use navigable
    waters.
    46
    structure put in place to balance the various priorities involved, and the
    fact that the plaintiffs had not alleged any private encroachment, the court
    saw “no need to extend the judiciary’s common-law role in this instance.”
    Id. at 386 (emphasis added).      That court’s discussion of the heavily-
    regulated field of water rights weighed into the issue of whether to
    recognize a new cause of action; it did not preclude the judiciary’s
    consideration of the cause of action altogether. Notably, other states have
    recognized “[p]reventing pollution and protecting the quality of the waters
    of the state . . . as being part of the state’s affirmative duty under the
    ‘public trust’ doctrine.” Wis. Env’t Decade, Inc. v. Dep’t of Nat. Res., 
    271 N.W.2d 69
    , 76 (Wis. 1978); see also Ralph W. Johnson, Water Pollution
    and the Public Trust Doctrine, 19 Env’t L. 485, 488 & n.13 (1989) (“[I]n
    recent years, courts have increasingly identified water quality as a
    separate or specific, rather than derivative, interest protected by the public
    trust doctrine.” (citing Nat’l Audubon Soc’y v. Superior Ct., 
    658 P.2d 709
    (Cal. 1983))).
    We engaged in a similar analysis in Bushby v. Washington County
    Conservation Board, 
    654 N.W.2d 494
    .            Contrary to the majority’s
    characterization of Bushby, we did not reject the plaintiffs’ claim because
    the county supervisors were entitled to deference.          Rather, we first
    determined that the public trust doctrine, which had originally applied to
    beds of navigable waters and had been expanded to include recreational
    use of lakes and rivers, should not be extended to apply to management
    of forested areas of public lands. 
    Id.
     at 497–98. That expansion would
    have gone well beyond the navigable water baseline (one might say the
    doctrine’s high water mark) that undergirds our understanding of the
    public trust doctrine, even as we have expanded its scope within the
    confines of navigable waters. See 
    id.
     It was only after determining the
    47
    limits of the doctrine that we then concluded it could not serve as an
    impediment to a public body’s otherwise lawful management of public
    lands. 
    Id.
     Bushby establishes that the scope of the public trust doctrine
    determines whether it could serve as a limit on the management of certain
    natural resources, which necessarily requires a determination of whether
    the doctrine applies to the particular controversy at issue. If it does, then,
    like any other constitutionally protected right, this court has the ability,
    indeed the responsibility, to determine if the state’s actions have violated
    those rights.
    The majority uses this same reasoning from White Bear and Bushby
    but repackages it—purportedly without first deciding the merits of the
    public trust doctrine—to support its assertion that the plaintiffs’ requested
    declaratory and injunctive relief is too speculative by encroaching on the
    legislative and executive branches’ balancing of uses for water in the
    Raccoon River between farmers’ economic interests and the plaintiffs’
    interests, surmising the plaintiffs’ requested relief could ultimately lead to
    even higher out-of-pocket expenditures for the plaintiffs’ members. While
    giving lip service to the doctrinal notion that “standing does not depend on
    the legal merits of a claim,” Godfrey v. State, 
    752 N.W.2d 413
    , 420 (Iowa
    2008), the majority necessarily addresses the merits by basing its standing
    holding on the premise that the public trust doctrine does not provide the
    protections the plaintiffs allege. In concluding we can offer no remedy, the
    majority has necessarily decided the doctrine does not extend to the
    plaintiffs’ claims.
    One more point from White Bear. Unlike the plaintiffs in White Bear,
    who did “not allege that the DNR has violated its duty as trustee to protect
    public use from ‘private interruption and encroachment,’ [a] core rationale
    of the [public trust] doctrine,” 946 N.W.2d at 386, here, the plaintiffs do
    48
    allege that the State defendants violated their duty as trustee to protect
    public use of the Raccoon River from pollution caused by private parties,
    parties currently being regulated by the defendants.                    But the State’s
    litigation strategy not to challenge whether the plaintiffs have stated a
    claim in its motion to dismiss prevents us from reaching the merits of the
    plaintiffs’ public trust claim. Believing the case is doomed anyway, and
    attempting to “do better” than embroil our courts in a decades-long battle
    that will result in, at best, lackluster results for the plaintiffs, the majority
    short circuits the process based on its ultimate view of the case to order
    dismissal for lack of standing and the existence of nonjusticiable political
    questions.
    Given the entanglement between “the political question grounds and
    the failure to state a claim grounds,” King, 818 N.W.2d at 12, the State
    insisting it is not challenging the merits or constitutional underpinnings
    of the public trust doctrine precludes its justiciability argument. See Luse,
    
    254 N.W.2d at
    327–28 (“Iowa courts have power to adjudicate substantial
    claims of deprivation of federal or Iowa constitutional rights . . . .”).12
    With respect to standing, I believe the plaintiffs’ request for a
    declaration of their rights and the State’s obligations meets the
    redressability threshold, assuming redressability applies as the majority
    insists. See Kanuk, 335 P.3d at 1095 (rejecting redressability argument,
    explaining: “Assuming the existence of a fiduciary duty on the part of the
    State to protect a public resource, the duty would not seem to depend on
    12The majority dismisses the plaintiffs’ request for a declaration of their
    constitutional rights on the basis that State ex rel. Dickey v. Besler, 
    954 N.W.2d 425
     (Iowa
    2021), too, involved constitutional issues, and that did not stop us from finding the claim
    to present a political question. But Besler involved a quo warranto action where a private
    citizen, Gary Dickey, challenged the public office held by another even though Dickey had
    no claim to the office. See 
    id.
     at 430–31, 433–34. This is not just a case involving
    constitutional issues, but a claim that the State is violating the plaintiffs’ rights under
    the constitution.

    the source of the threatened harm”).        We have never shied away from
    declaring rights of beneficiaries and obligations of trustees. See, e.g., In re
    Steinberg Fam. Living Tr., 
    894 N.W.2d 463
    , 468 (Iowa 2017) (considering a
    declaratory judgment action to interpret a trust). And courts around the
    country recognize the importance of the judiciary’s role in defining the
    scope and applicability of the public trust doctrine.         “Just as private
    trustees are judicially accountable to their beneficiaries for dispositions of
    the res, so the legislative and executive branches are judicially accountable
    for their dispositions of the public trust.” Ariz. Ctr. For L. In Pub. Int. v.
    Hassell, 
    837 P.2d 158
    , 169 (Ariz. Ct. App. 1991) (citation omitted) (“The
    check and balance of judicial review provides a level of protection against
    improvident dissipation of an irreplaceable res.”); see also Kootenai Env’t
    All., Inc. v. Panhandle Yacht Club, Inc., 
    671 P.2d 1085
    , 1092 (Idaho 1983)
    (“Final determination whether the alienation or impairment of a public
    trust resource violates the public trust doctrine will be made by the
    judiciary. . . . [T]his court will take a ‘close look’ at the action to determine
    if it complies with the public trust doctrine and it will not act merely as a
    rubber stamp for agency or legislative action.”); Op. of the Justs., 
    437 A.2d 597
    , 607 (Me. 1981) (applying “a high and demanding standard of
    reasonableness” to judicial review of legislative action releasing state’s
    ownership of submerged and intertidal lands that were subsequently filled
    for compliance with the Legislative Powers Clause). As Justice McDonald
    also points out, the Solicitor General conceded at oral argument that the
    plaintiffs would have standing to pursue, at minimum, their claims for
    declaratory relief.
    Against this authority and the State’s concession, the majority’s
    dismissive characterization of the plaintiffs’ requested declaratory relief as
    too general rings hollow. It is not enough to say that protecting against
    50
    pollution is not alienating or limiting access to navigable waters; that
    would be addressing the merits of the plaintiffs’ claims.
    With respect to the plaintiffs’ requested injunctive relief, the State is
    currently regulating the third-party nonpoint sources allegedly causing the
    nitrate pollution, but, according to the plaintiffs, they are doing so
    ineffectively through a voluntary compliance strategy. If a court struck
    the legislatively mandated adoption of the voluntary-based strategy as a
    violation of the public trust doctrine while also declaring the State has a
    constitutional obligation to manage pollution in the Raccoon River,
    removal of the statute would free state agencies to regulate storm runoff
    through a mandatory regime as requested by the plaintiffs. For purposes
    of a motion to dismiss, we “assume[] that the state will act in accordance
    with a judicially issued declaration regarding the scope of any duties that
    the state may have under the public trust doctrine.” Chernaik, 328 P.3d
    at 807; cf. Butler ex rel. Peshlakai, 
    2013 WL 1091209
    , at *6–8 (recognizing
    scope and enforcement of public trust doctrine is within court’s power to
    adjudicate but dismissing declaratory judgment claim challenging state
    agency’s failure to regulate greenhouse gas emissions for lack of a remedy
    where plaintiff failed to challenge constitutionality of the statute
    preventing state agencies from doing so absent express legislative
    authorization, similar to section 20 of Senate File 512 challenged here).
    The plaintiffs’ requested declaratory and injunctive relief, if granted, would
    provide sufficient redressability for the plaintiffs’ claimed injuries to meet
    constitutional standards.
    The State’s insistence that, for purposes of its motion to dismiss, the
    public trust doctrine grants the rights and imposes the obligations
    asserted by the plaintiffs requires us to affirm the district court’s denial of
    the State’s motion to dismiss and allow the case to proceed.

    I therefore respectfully dissent.
    Appel, J., joins this dissent.
