    The Department of Fish and Wildlife (Department) appeals from a judgment in
    favor of the Siskiyou County Farm Bureau (Farm Bureau), interpreting a statute requiring
    notification when an entity plans to “substantially divert” water from a river or stream.
    We shall reverse because the trial court incorrectly found the statute, Fish and
    Game Code section 1602,1 to be ambiguous, and then resolved the perceived ambiguity
    in a manner inconsistent with the plain language of the statute.
    Regardless of an entity’s legal right to take water, such as for agricultural
    purposes, and regardless of whether the taking alters the streambed itself, section 1602
    unambiguously requires notification to the Department if an entity plans to “substantially
    divert” water. After notification, a statutory mechanism--arbitration followed by court
    review--exists to resolve disputes about diversions. This notification requirement neither
    encroaches on any entity’s water rights, nor impairs the powers and duties of the State
    1   Further undesignated section references are to the Fish and Game Code.
    2
    Water Resources Control Board (Board), which has filed an amicus brief fully supporting
    the Department’s position.2
    As we will explain, the trial court appears to have been led astray by a
    questionable and aborted enforcement policy issued by a single Department employee
    (the “Stopher criteria”), as well as the deluge of extrinsic material proffered by the Farm
    Bureau in its effort to demonstrate a latent ambiguity in the statute. As we have recently
    cautioned, although extrinsic evidence may reveal a latent ambiguity in a statute, such
    ambiguity must reside in the statutory language itself. It cannot exist in the abstract, or
    by ignoring the statutory language. (See Alameda County Flood Control & Water
    Conservation Dist. v. Department of Water Resources (2013) 
    213 Cal. App. 4th 1163
    ,
    1179-1180, 1188-1190, 1195 (Alameda).) Here, the extrinsic evidence reveals no
    ambiguity in the statute: The term “divert” had a long-established meaning in the context
    of water law before enactment of the statute, and we presume the Legislature was aware
    of that meaning when it used divert as it did in section 1602.
    If the Farm Bureau and allied amici curiae believe the statute as written reflects
    poor public policy, a remedy lies “on the other side of Tenth Street, in the halls of the
    Legislature.” (Osborn v. Hertz Corp. (1988) 
    205 Cal. App. 3d 703
    , 711.)
    PROCEDURAL BACKGROUND
    The Farm Bureau filed a complaint for declaratory relief alleging that for over a
    century “ranchers and farmers in Siskiyou County have extracted water from streams and
    rivers to irrigate crops and pastures, to water livestock, and for use in their homes and
    2 Amici curiae allied with the Department include: 1) the Board; 2) a group of
    prominent law professors from several California law schools; 3) the Karuk Tribe, Pacific
    Coast Federation of Fishermen’s Associations, Institute for Fisheries Resources, and
    Klamath Riverkeeper; and 4) California Trout and Trout Unlimited. Amici curiae allied
    with the Farm Bureau include: 1) the Northern California Water Association; and 2), the
    Pacific Legal Foundation and the California Cattlemen’s Association.

    businesses. Not until now, some fifty years after the legislature adopted . . . sections
    1600 et seq., has [the Department] asserted that [such extraction] requires compliance
    with section 1602 regardless of whether there is any alteration of a river, stream, or lake.”
    Farmers and ranchers either had to comply with this new interpretation or risk “civil and
    criminal prosecution. For this reason, [the Farm Bureau] brings this action for
    declaratory relief to clarify the rights and duties of its members under . . . section 1602
    who do not alter the streambed in exercising their water rights.” The purportedly new
    interpretation referenced by the complaint was based on the Stopher criteria, which
    presumed that any diversion of water within the relevant watershed was a substantial
    diversion within the meaning of section 1602.
    The Department unsuccessfully moved for judgment on the pleadings, and the
    parties then contested whether or not the statute--as proposed to be applied--was
    ambiguous. The trial court found it was.
    To resolve the question of statutory ambiguity, the trial court considered extrinsic
    evidence and resolved the purported ambiguity against the Department, which timely
    appealed from a judgment prohibiting it from “bringing enforcement action against
    agricultural water diverters for failing to notify the department of the diverter’s intention
    to lawfully exercise his water right absent alteration to the bed, bank, or stream.”
    DISCUSSION
    The trial court found the statute’s plain meaning supported the Department’s view
    that the word divert encompassed diversions that did not alter the streambed itself, but
    found there was a latent ambiguity and applying the plain meaning would lead to absurd
    results, raise doubts about the constitutionality of the statute, and cause a conflict
    between the Department’s duties and the Board’s duties.
    We agree with the trial court that the plain meaning of the statute supports the
    Department’s position. Our agreement, however, ends there. Although the Department’s
    interpretation of the statute plausibly accounts for the statutory language, the Farm
    4
    Bureau has not proffered a candidate of meaning that also plausibly accounts for the
    statutory language, and therefore has failed to show an ambiguity in the statute when the
    rules governing statutory ambiguity are correctly applied. None of the extrinsic evidence
    tendered by the Farm Bureau changes this conclusion. We reject the trial court’s
    conclusion that the absurd result or constitutional doubt rules require departing from the
    plain meaning of the statute, as well as its finding that application of section 1602’s plain
    meaning would allow the Department to intrude into the Board’s bailiwick.
    We shall reverse with directions to enter judgment in favor of the Department.
    I
    The Meaning of Divert in Section 1602
    Section 1602 now provides in relevant part:
    “An entity may not substantially divert or obstruct the natural flow of, or
    substantially change or use any material from the bed, channel, or bank of, any
    river, stream, or lake, or deposit or dispose of debris, waste, or other material
    containing crumbled, flaked, or ground pavement where it may pass into any river,
    stream, or lake, unless all of the following occur [listing notification and other
    requirements.]” (§ 1602, subd. (a).)
    The trial court found the plain meaning of divert as used in section 1602 was
    broad and supported the Department’s position herein. Yet the trial court then found a
    latent ambiguity in the term. As we now explain, there is no semantic ambiguity as
    posited by the Farm Bureau, latent or otherwise.
    First, we review some basic principles of California water law, to establish the
    background for the specific legislation at issue. (Part I-A, post.) Next, we briefly
    describe the devastating effect of the Gold Rush on California’s rivers and streams, again
    to provide background for the relevant legislation. (Part I-B, post.) We then describe the
    history of section 1602. (Part I-C, post.) We then discuss early interpretations of section
    1602. (Part I-D, post.) Finally, we consider whether any proffered extrinsic evidence
    establishes an alternative equally plausible candidate of meaning of divert as used in
    5
    section 1602, and conclude no such alternative meaning has been demonstrated. (Part I-
    E, post.)
    A. Basic California Water Law Principles
    Because the trial court spent much time on basic water law principles which are
    assumed by the parties, we provide the reader with a brief summary, taken from a recent
    case:
    “Ownership of California’s water is vested generally in the state’s
    residents, but individuals and entities can acquire ‘water rights,’ the right to divert
    water from its natural course for public or private use. [Citations.] California
    maintains a ‘dual system’ of water rights, which distinguishes between the rights
    of ‘riparian’ users, those who possess water rights by virtue of owning the land by
    or through which flowing water passes, and ‘appropriators,’ those who hold the
    right to divert such water for use on noncontiguous lands. [Citation.] For
    historical reasons, California further subdivides appropriators into those whose
    water rights were established before and after 1914. Post-1914 appropriators may
    possess water rights only through a permit or license issued by the Board, and
    their rights are circumscribed by the terms of the permit or license. . . .
    [¶] . . . [¶]
    “The nature of the water rights held by riparian users and appropriators
    differs in several ways. Most pertinent to the matter at hand are the limits placed
    on diversion. Although riparian users must share with other riparian users on the
    watercourse, there is no predetermined limit on the amount of water an individual
    riparian user may divert, so long as the uses to which the diverted water is put are
    riparian, beneficial, and reasonable. [Citation.] Appropriators, in contrast, may
    divert only so much water as is authorized by their particular water right. . . .
    [¶] . . . [¶]
    “[W]ater use by both appropriators and riparian users is limited by the
    ‘reasonable use’ doctrine, which forbids the waste of water or its unreasonable
    use.” (Millview County Water Dist. v. State Water Resources Control Bd. (2014)
    
    229 Cal. App. 4th 879
    , 888-890, fns. omitted.)3
    3 California’s water rights system is not really dual but is instead tripartite, because some
    pueblo rights superior to riparian or appropriative rights exist. (See Hutchins, The Cal.
    6
    In addition, the public trust doctrine vests the state with sovereign authority over
    all navigable waterways. (See 
    Audubon, supra
    , 33 Cal.3d at pp. 433-441.) “It is an
    affirmation of the duty of the state to protect the people’s common heritage of streams,
    lakes, marshlands and tidelands, surrendering that right of protection only in rare cases
    when the abandonment of that right is consistent with the purposes of the trust.” (Id. at p.
    441.) An overarching principle is that “the general welfare requires that the water
    resources of the state be put to beneficial use to the fullest extent to which they are
    capable, and that the waste or unreasonable use of water must be prevented [citations].
    [¶] Just as the State of California holds all of its navigable waterways and the lands lying
    beneath them as a trustee of a public trust for the benefit of the People [citation], the state
    acts as a trustee of all waters for the benefit of the People of the State [citation].” (People
    v. Weaver (1983) 
    147 Cal. App. Supp. 3d 23
    , 28-29, fn. omitted (Weaver).)4
    In all contexts, water use must be reasonable, as stated by our Supreme Court:
    Law of Water Rights (1956) Pueblo Water Right, pp. 256-262 (Hutchins).) A useful
    expanded summary of the history of California water law is provided by Pleasant Valley
    Canal Co. v. Borror (1998) 
    61 Cal. App. 4th 742
    , at pages 750-754 (Pleasant Valley).
    4  The parties seem to assume the relevant waterways are navigable, but do not explicitly
    so state. Audubon did not consider “whether the public trust extends for some purposes--
    such as protection of fishing, environmental values, and recreation interests--to
    nonnavigable streams.” (
    Audubon, supra
    , 33 Cal.3d at p. 437, fn. 19.) But a separate
    line of authority holds that fish are subject to a species of the public trust doctrine. (See
    People v. Monterey Fish Products Co. (1925) 
    195 Cal. 548
    , 563; California Trout, Inc. v.
    State Water Resources Control Bd. (1989) 
    207 Cal. App. 3d 585
    , 630 (California Trout).)
    Although we agree with amicus curiae Northern California Water Association’s
    assertion that the state does not “own” all water, rather, the water is owned by the people
    of California (see Wat. Code, § 102 [“All water within the State is the property of the
    people of the State, but the right to the use of water may be acquired by appropriation in
    the manner provided by law”]; see State of California v. Superior Court (2000) 
    78 Cal. App. 4th 1019
    , 1022-1028 [insurance coverage case]), we find this distinction to be of
    no relevance to our decision.
    7
    “It is well established that what is a reasonable use of water varies with the
    facts and circumstances of the particular case. [Citations.] [T]he reasonableness
    of a riparian use cannot be determined without considering the effect of such use
    on all the needs of those in the stream system [citation], nor can it be made ‘in
    vacuo isolated from statewide considerations of transcendent importance.’
    [Citation.] These statewide considerations are that ‘limited water resources be put
    only to those beneficial uses “to the fullest extent of which they are capable,” that
    “waste or unreasonable use” be prevented, and that conservation be exercised “in
    the interest of the people and for the public welfare.” (Cal. Const., art. XIV, § 3
    [now art. X, § 2].)’ ” (In re Waters of Long Valley Creek Stream System (1979) 
    25 Cal. 3d 339
    , 354 (Long Valley); see Light v. State Water Resources Control Bd.
    (2014) 
    226 Cal. App. 4th 1463
    , 1479-1480.)
    B. The California Gold Rush and Aftermath
    “Over [150 years ago], gold drew throngs of adventurers to early mining
    communities in the Sierra Nevada. When the halcyon years were over, a few earnest
    argonauts decamped and went to the river bottoms, and pointed great water cannons,
    called monitors, at the hillsides hoping to dislodge sparkles of gold from the sandy
    detritus . . . . [¶] Although considerable quantities of gold washed down and were
    separated from the gravel, the hydraulic mines annually discharged 600,000 cubic yards
    of debris, which soon choked the American and Sacramento Rivers with tailings, raised
    the beds of these rivers, impairing navigability, fouling the waters, and angering farmers.
    [¶] Amid political turmoil, the matter finally reached our high court, which held that an
    injunction should issue, based upon the premise that the rights of the people in navigable
    rivers were paramount, and that any intrusions upon that right constituted a nuisance.”
    
    (Weaver, supra
    , 147 Cal.App.3d Supp. at p. 30; see 
    Audubon, supra
    , 33 Cal.3d at p. 436
    [damage from mining debris]; Paterno v. State of California (2003) 
    113 Cal. App. 4th 998
    ,
    1004-1005 [observing that the “damage [from hydraulic mining] is indescribable, and
    must be seen at the Malakoff Diggins State Historic Park to be believed”].)
    8
    C. The Origin of Section 1602
    The injunctive relief just mentioned (see People v. Gold Run D. & M. Co. (1884)
    
    66 Cal. 138
    ; see also Woodruff v. North Bloomfield G. Min. Co. (1884) 9 Sawy. 441, 18
    Fed. 753) had significant consequences:
    “[These] decision[s] led to the virtual demise of hydraulic mining, and the
    Legislature finally responded by declaring that hydraulic mining could only be
    carried on if it could be done without material injury to navigable streams or the
    lands adjacent thereto [citation]. . . . In addition, one who desires to [deflect], alter
    or divert the course of a nonnavigable stream in any surface mining dredging
    operation must obtain the approval of the board of supervisors [citation].
    “Turning our attention to the immediate origins of [section 1602], it appears
    over the years, the Legislature, concerned with the decline in the fish population,
    enacted a number of laws including those, 1) prohibiting persons from depositing
    any substance or material deleterious to fish where it could pass into the waters of
    the state [citations], 2) prohibiting mining operations in the Trinity and Klamath
    game district for four months each year, except when mining debris could not pass
    into the waters, [citation], 3) making it unlawful to construct or maintain devices
    in certain streams which impeded the passing of fish up and down the stream
    [citation], 4) authorizing the Fish and Game Commission to require the owner of
    any new or enlarged dam to install and maintain fishways [citations], and, 5)
    allowing access to waters impounded by a dam to fishermen during the open
    season [citations].
    “Despite these efforts, siltation caused by the removal and washing of
    aggregate seriously affected anadromous fish, such as salmon and steelhead, by
    preventing spawning and suffocating eggs and fry. Aggregate operations had
    rendered certain portions of the Tuolumne River useless for spawning and placed
    the American River in jeopardy. [Citations.]
    “Therefore, the Legislature enacted [section 1602] which makes it unlawful
    to substantially divert or obstruct the natural flow, or substantially change the
    bank, of any stream or lake, or to use any material from the streambeds, without
    first notifying the Department. Section 1601 . . . also requires governmental
    entities to notify the Department of any project which will divert, obstruct or
    change the natural flow of any river, stream or lake, or if there is at any time a fish
    or wildlife resource, or from which these resources derive benefit, or when the
    project will use materials from streambeds designated by the Department
    [citation].” 
    (Weaver, supra
    , 147 Cal.App.3d Supp. at pp. 31-32, fn. omitted.)
    9
    The purpose of remediating adequate spawning reaches for anadromous fish was
    detailed in a 1959 legislative report introduced as extrinsic evidence at trial. (Sen.
    Permanent Fact Finding Com. on Natural Resources (1961 Reg. Sess.).) We will refer to
    this as the Senate Report.
    Originally enacted as part of a new Chapter 6 of Division 2 of the code, former
    section 1602 provided in significant part: “Any person who substantially diverts or
    obstructs the natural flow or substantially changes the bed, channel or bank of any river,
    stream or lake, or uses any material from the streambeds, shall notify the department of
    such operations, except when the department has been notified pursuant to Section 1601.
    The department within 30 days of receipt of such notice, or within the time determined by
    mutual written agreement, shall submit to the person its recommendations as to measures
    necessary to protect fish and wildlife.” (Stats. 1961, ch. 909, § 2, p. 2532.)5
    As we have explained in a prior case, in 1970 the Legislature prohibited diversions
    until an agreement was reached with the Department, and arbitration provisions were
    added to facilitate disputes. We emphasized that violations of the section, then
    renumbered 1603 (Stats. 1970, ch. 1357, § 2, p. 2524), “either by failure to notify the
    Department of a project or by refusing to incorporate the Department’s proposed project
    modifications or the decision of the arbitration panel into the project, became a
    misdemeanor” (Willadsen v. Justice Court (1983) 
    139 Cal. App. 3d 171
    , 176 (Willadsen)).
    In 1976, Chapter 6 was repealed and revised (Stats. 1976, ch. 603, §§ 1-2, pp.
    1447-1451), and by regulation the Department declared “all rivers, streams, lakes, and
    streambeds” to be subject to its provisions. (See 
    Willadsen, supra
    , 139 Cal.App.3d at p.
    5 We deem references in some authorities to section 1603--the statute’s number between
    1970 and 2003--to refer to section 1602, as do the parties. (See People v. Osborn (2004)
    
    116 Cal. App. 4th 764
    , 767, fn. 1 (Osborn).) Similarly, references to the Department of
    Fish and Game are to the Department.
    10
    175; see 
    id. at pp.
    173-175.) In 2003, Chapter 6 was again repealed and revised,
    rewriting its sections to read as they do at present. (See Stats. 2003, ch. 736, § 2, pp.
    5522-5532.)
    As relevant to the current dispute, section 1602 can be parsed to read as follows:
    “An entity may not [1] substantially divert or obstruct the natural flow of,
    or [2] substantially change or use any material from the bed, channel, or bank of,
    any river, stream, or lake, or [3] deposit or dispose of debris, waste, or other
    material . . . where it may pass into any river, stream, or lake [absent, inter alia,
    notification to the Department].”
    The Legislature has declared section 1602’s explicit legislative purpose to be as
    follows: “The Legislature finds and declares that the protection and conservation of the
    fish and wildlife resources of this state are of utmost public interest. Fish and wildlife are
    the property of the people and provide a major contribution to the economy of the state,
    as well as providing a significant part of the people’s food supply; therefore their
    conservation is a proper responsibility of the state. This chapter is enacted to provide
    conservation for these resources.” (§ 1600; Stats. 2003, ch. 736, § 2, pp. 5522-5523.)
    With insubstantial changes, this is the same purpose as when the statute was first enacted.
    (See Stats. 1961, ch. 909, § 2, p. 2532.)6
    D. Early Interpretations of Section 1602
    Questions soon arose surrounding the interpretation of “substantially” and
    “divert.” Some argued that substantially was too vague, and some, including the Farm
    Bureau and allied amici curiae, contend divert refers to diverting the streambed itself, and
    not merely pumping (or otherwise taking) water therefrom. Although divert is the key
    6 Although relevant only in cases of demonstrated ambiguity, “laws providing for the
    conservation of natural resources are to be given a liberal construction.” (Outfitter
    Properties, LLC v. Wildlife Conservation Bd. (2012) 
    207 Cal. App. 4th 237
    , 245; see
    Blumenfeld v. San Francisco Bay Conservation etc. Com. (1974) 
    43 Cal. App. 3d 50
    , 56.)
    11
    term for our purposes, some discussion of both terms is necessary to fully understand the
    contentions on appeal.
    The claim that the word substantially was too vague was easily rejected. (See
    Rutherford v. State of California (1987) 
    188 Cal. App. 3d 1267
    , 1279 (Rutherford);
    
    Weaver, supra
    147 Cal.App.3d Supp. at pp. 36-38.) “The term ‘substantial’ has assumed
    a commonly understood meaning as characterizing something as ample or of
    considerable amount, quantity or size; while within the legal context, it has been defined
    as important or material and of considerable amount or value rather than inconsequential
    or small.” (Rutherford, at p. 1279.) “[I]t is the role of the Department to determine
    whether the individual’s proposed activity will affect the existing fish or wildlife
    resources. Consequently, because notice is required under the statute before an
    individual acts and equally mindful of the breadth of the ordinance, this determination
    rests upon the Department and not the individual. In other words, there exists no due
    process consideration regarding an individual’s conformity with the strictures of the
    statute.” (Id. at p. 1280, fn. 4.)
    The notification leads to arbitration if the parties cannot agree whether a
    substantial diversion has occurred or what remedial measures suffice, and the arbitral
    result is subject to judicial review. (See §§ 1603, 1604; Code Civ. Proc., § 1285; see
    Environmental Protection Information Center v. California Dept. of Forestry & Fire
    Protection (2008) 
    44 Cal. 4th 459
    , 518 [describing the notification and protest procedure];
    see 
    Osborn, supra
    , 116 Cal.App.4th at p. 771 [purpose of notice “is so the Department
    can ensure that fish and wildlife resources are protected”].)7
    7 One case suggested the method of review would be a petition for writ of mandate
    (Code Civ. Proc., § 1094.5) to challenge permit conditions. 
    (Rutherford, supra
    , 188
    Cal.App.3d at p. 1286.) We express no view of the viability of that mechanism.
    12
    As for the term divert, the California Attorney General and one court have
    impliedly or directly invited the Legislature to clarify its meaning, to no avail.
    In 1973, the California Attorney General considered, inter alia, whether a “person
    diverting water from a stream by means of a pump” was subject to former section 1602.
    (See 56 Ops.Cal.Atty.Gen 360 (1973).) While discussing related questions, the Attorney
    General pointed out that “the same factor which provides for steelhead and salmon
    spawning beds is that which attracts aggregate companies, an abundance of gravel. The
    Legislature was specifically concerned over the protection of salmon and steelhead
    spawning gravels from adverse aggregate operations when sections 1600 through 1603
    were originally enacted in 1961.” (Id. at p. 362, citing the Senate Report.) “Many
    spawning riffles that are used by salmon and steelhead during high flows are completely
    dry and exposed during low summer flows. . . . [¶] . . . [¶] Aggregate companies during
    the long summer months can and do operate in these dry areas located in the flood plain
    and remove such gravel used for spawning in the winter. It is clear that a legislative
    purpose of [former] section 1602 was to protect gravels used by salmon and steelhead for
    spawning from aggregate operations.” (Id. at p. 363.)
    In language relevant to this appeal, the 1973 Attorney General opinion finds:
    “Section 1602 applies to ‘any person who substantially diverts . . . the
    natural flow . . . of any river, stream . . . .’
    “Of course this provision applies to any method of diversion. The difficult
    question is what constitutes a ‘substantial’ diversion of the natural flow. At least
    two possible detrimental effects on fish and wildlife resources come to mind.
    Pump diversions can divert all of the flow of a stream thus dewatering the area
    downstream. Pump diversions can also suck in small fish.
    “Any pump diversion or series of pump diversions that are capable of
    dewatering a stream at extreme low summer flows or greater flows, or could result
    in detriment to fishlife in the stream because of flow reduction would constitute
    substantial diversion of the natural flow and thus come within the purview of
    [former] section 1603.
    13
    “All pump diversions are capable of diverting small fish, fry and eggs out
    of a stream, river, or lake but a general rule cannot be laid down for what would
    constitute a substantial diversion, because of the innumerable factual variations.”
    (56 
    Ops.Cal.Atty.Gen., supra
    , at pp. 364-365, italics added.)8
    Thus, the 1973 Attorney General opinion concluded that mere pumping qualified
    as a diversion under the statute, but added the caveat that whether a diversion was
    substantial depended on the specific facts of each case.
    Ten years later, Weaver (decided in 1983) contained a cautionary dictum, albeit in
    the context of defining substantial rather than divert:
    “In enacting [former section 1602], we feel confident that the Legislature
    was not concerned with children skipping rocks across a stream, or building sand
    castles, or hikers dislodging a few stones as they climbed the bank of a river. On
    the contrary, by using the word substantially, the Legislature certainly intended to
    prohibit an owner from bulldozing material in a streambed which would cause the
    stream to change its course materially, or a like change which might interfere with
    the spawning grounds of anadromous fish, unless the plans were first approved by
    the Department (or found to have an insignificant effect upon the ecosystem in the
    vicinity of the projected change). Our conclusion is fortified by the language
    which prohibits using any material from the streambeds unless the Department
    was notified. Therefore, a person moving sand or gravel from a streambed acts at
    his peril unless he or she first notifies the Department.
    “We acknowledge that there are grounds for valid differences of opinion as
    to what constitutes a substantial diversion of the natural flow of a stream. This
    same issue troubled the Attorney General a decade ago, and apart from the
    problem of quantifying what is meant by a substantial diversion, we wonder how
    this particular prohibition may affect farmers who exercise riparian rights and
    who might be wholly unaware of this law. We suggest that this subject merits
    reconsideration by the Legislature.” 
    (Weaver, supra
    , 147 Cal.App.3d Supp. at pp.
    37-38, italics added.)
    Thus, Weaver raised a concern that the statute might have been written more
    broadly than intended, because it could be read to cover ordinary agricultural pumping,
    8 The next year, another opinion concluded criminal liability could ensue, in part, should
    a person “divert or obstruct a stream or river and then willfully fail to notify” the
    Department. (57 Ops.Cal.Atty.Gen. 475, 476 (1974), italics added.)
    14
    without movement of gravel or obstruction of a spawning reach. There was no legislative
    action to address the concerns expressed by Weaver or by the earlier Attorney General
    opinion.
    For multiple reasons, we agree with the conclusion of the 1973 Attorney General
    opinion that section 1602 plausibly encompasses pumping.
    First, the phrase “any person” refers to every person or entity who substantially
    diverts water. “Generally, ‘any’ means all or every. ‘From the earliest days of statehood
    the courts have interpreted “any” to be broad, general, and all embracing.’ (Burnsed v.
    State Bd. of Control (1987) 
    189 Cal. App. 3d 213
    , 217; see Emmolo v. Southern Pacific
    Co. (1949) 
    91 Cal. App. 2d 87
    , 92 [‘the use of the word “any” in the statute negatives the
    contention that the statute is restricted . . . ’].)” (California Grocers Assn. v. Department.
    of Alcoholic Beverage Control (2013) 
    219 Cal. App. 4th 1065
    , 1078 (conc. opn. of Duarte,
    J.).)
    Moreover, we cannot overlook the use of “or” in the statute, first appearing in the
    clause referencing an act to “substantially divert or obstruct” water. (§ 1602, subd. (a),
    italics added.) The usage of “or” between divert and obstruct, unaccompanied by any
    indication that what follows is qualified, “indicates an intention to use [the word “or”]
    disjunctively so as to designate alternative or separate categories.” (White v. County of
    Sacramento (1982) 
    31 Cal. 3d 676
    , 680; see Smith v. Selma Community Hospital (2010)
    
    188 Cal. App. 4th 1
    , 30.) Thus, the later references in the statute to gravel etc. do not
    operate to limit the word divert. Another significant “or” occurs later in the same
    sentence: “An entity may not substantially divert or obstruct the natural flow of, or
    substantially change or use any material from the bed, channel, or bank of” any stream
    or river. (§ 1602, subd. (a), italics added.) This shows a difference between “divert or
    obstruct” and “substantially change” and shows that a proposed activity that either will
    “divert or obstruct” or “substantially change or use any material from” the streambed is
    covered by the statute. Similarly, a third activity, one that will “deposit or dispose of
    15
    debris, waste, or other material” into a stream may trigger a notification requirement.
    (§ 1602, subd. (a).) The placement of commas confirms our reading, as they “are used to
    separate items in a list.” (Board of Trustees v. Judge (1975) 
    50 Cal. App. 3d 920
    , 927, fn.
    4.)
    Further, whether a diversion is substantial cannot be answered in the abstract, but
    depends on the innumerable factual variations as stated by the 1973 Attorney General
    opinion. Some of these considerations are the amount of water taken relative to the
    supply, the use to which such water is applied, the historical usage by the diverter and
    predecessors, and the needs of the fish, given the palpable fact that--due to yet another in
    a series of recurring drought conditions in California--there simply is not enough water to
    satisfy all legitimate needs. But this does not import into the statute an exemption for
    diversions by pumping.
    Finally, “ ‘Opinions of the Attorney General, while not binding, are entitled to
    great weight. [Citations.] In the absence of controlling authority, these opinions are
    persuasive “since the Legislature is presumed to be cognizant of that construction of the
    statute.” ’ ” (California Assn. of Psychology Providers v. Rank (1990) 
    51 Cal. 3d 1
    , 17
    (Rank); see Meyer v. Board of Trustees (1961) 
    195 Cal. App. 2d 420
    , 432 [“It must be
    presumed that the aforesaid interpretation has come to the attention of the Legislature,
    and if it were contrary to the legislative intent that some corrective measure would have
    been adopted in the course of the many enactments on the subject in the meantime”]; see
    also People v. Gjersvold (2014) 
    230 Cal. App. 4th 746
    , 751; see Rank, at p. 17.)
    The Legislature could easily have amended section 1602 if it perceived an
    interpretive problem. Indeed, as the trial court in this case observed, Weaver asked the
    Legislature to clarify what constituted a substantial diversion under the statute 
    (Weaver, supra
    , 147 Cal.App.3d Supp. at pp. 33, 38), yet the Legislature did not do so. Thus it
    impliedly embraced the Attorney General’s interpretation, by declining to clarify the
    language at issue despite revising the statute in other ways over the years.
    16
    Interpreting the term divert as used in section 1602 to embrace diversions of water
    without alteration of or damage to the streambed itself is the most natural reading of the
    statute. However, although the Department has proffered this reading as a plausible
    candidate of meaning of the statute, we must examine other sources, including
    provisionally examining extrinsic sources, to determine if the Farm Bureau has tendered
    an equally plausible candidate of meaning and determine if an ambiguity exists.
    E. The Proffered Alternate Candidate of Meaning of Divert
    The next question is whether the Farm Bureau has proffered a plausible candidate
    of meaning, and thus has raised an ambiguity in the statute, latent or patent. “ ‘A claim
    of latent ambiguity requires a provisional examination of extrinsic matters to make the
    judgment whether the claim is tenable.’ ” 
    (Alameda, supra
    , 213 Cal.App.4th at p. 1180.)
    The Farm Bureau would read section 1602 to exclude activities that take water without
    disturbing the streambed or bank. Several types of extrinsic evidence were considered by
    the trial court and are proffered on appeal in support of this candidate. But before
    discussing the particular categories of extrinsic evidence, we briefly discuss what
    ambiguity is, and how it is shown.
    The question of statutory ambiguity is not merely a linguistic question--although it
    is that--it is a question striking at the heart of California’s lawmaking system. “The
    Legislature may make no law except by statute and may enact no statute except by bill.”
    (Cal. Const., art. IV, § 8; see People’s Advocate Inc. v. Superior Court (1986) 
    181 Cal. App. 3d 316
    , 325-326.) A statute is the mechanism for exercising legislative power.
    Thus, statutory language is the measure of its meaning, and not some progenitor, be it the
    author of a precursor bill, or detritus from the legislative process. (See, e.g., Lungren v.
    Deukmejian (1988) 
    45 Cal. 3d 727
    , 742; California Teachers Assn. v. San Diego
    Community College Dist. (1981) 
    28 Cal. 3d 692
    , 699-701.) Therefore, “[i]f the meaning
    of a statute can be declared without the support of a statutory text, the law is not made
    ‘by’ the statute, it is made by the courts in violation of the Constitution.” (City of
    17
    Sacramento v. Public Employees’ Retirement System (1994) 
    22 Cal. App. 4th 786
    , 795
    (Sacramento).)
    Thus, legislative history--a term now broadly used to mean the background
    materials that precede the enactment of a particular bill--is irrelevant unless it aids in
    resolving an ambiguity in the statutory language. (See People v. Snook (1997) 
    16 Cal. 4th 1210
    , 1215 [absent ambiguity “we presume the Legislature meant what it said and the
    plain meaning of the statute governs”].)
    “An ambiguity arises only if ‘ . . . there [is] more than one construction in issue
    which is semantically permissible, i.e., more than one usage which makes sense of the
    statutory language given the context and applicable rules of usage.’ ” 
    (Sacramento, supra
    , 22 Cal.App.4th at p. 795; see 
    Alameda, supra
    , 213 Cal.App.4th at pp. 1179-1180;
    California State Auto. Assn. Inter-Ins. Bureau v. Superior Court (1986) 
    177 Cal. App. 3d 855
    , 859, fn. 1 [same rule obtains regarding contractual ambiguity].)
    It is true that “[p]art of a fair reading of statutory text is recognizing that ‘Congress
    [or the Legislature] legislates against the backdrop’ of certain unexpressed
    presumptions.” (Bond v. United States (2014) 572 U.S. __, __ [
    189 L. Ed. 2d 1
    , 12].) But
    ambiguity is not shown by unexpressed presumptions unrelated to statutory text. “In
    determining whether language is ambiguous it is essential to tether extrinsic evidence to
    particular language: ‘ “The test of admissibility of extrinsic evidence to explain the
    meaning of a written instrument is not whether it appears to the court to be plain and
    unambiguous on its face, but whether the offered evidence is relevant to prove a meaning
    to which the language of the instrument is reasonably susceptible.” ’ [Citation.]
    Therefore, if ‘ “the language of the instrument” ’ cannot carry the meaning ascribed to it
    by the party claiming an ambiguity, ‘ “the case is over.” ’ ” 
    (Alameda, supra
    , 213
    18
    Cal.App.4th at pp. 1188-1189, quoting from Dore v. Arnold Worldwide, Inc. (2006) 
    39 Cal. 4th 384
    , 391-393.)9
    Moreover, the fact that “ ‘ “a statute can be applied in situations not expressly
    anticipated by [the Legislature] does not demonstrate ambiguity. It demonstrates
    breadth.” ’ ” (Estate of Earley (2009) 
    173 Cal. App. 4th 369
    , 376; see Souza v. Lauppe
    (1997) 
    59 Cal. App. 4th 865
    , 873-874.)
    “ ‘An ambiguity can be patent, arising from the face of the writing, or latent,
    based on extrinsic evidence.’ [Citation.] ‘A claim of latent ambiguity requires a
    provisional examination of extrinsic matters to make the judgment whether the claim is
    tenable.’ [Citations.] [¶] If extrinsic evidence factually conflicts, the trial court’s
    resolution of that conflict is reviewed for substantial evidence, otherwise the trial court’s
    . . . interpretation . . . is reviewed de novo.” 
    (Alameda, supra
    , 213 Cal.App.4th at p.
    1180.)
    With this understanding, we now examine the extrinsic evidence to determine if it
    shows the Farm Bureau’s interpretation plausibly accounts for the statutory language so
    that its interpretation stands in relative equipoise to the Department’s.
    1. Dictionary definitions
    “The dictionary is a proper source to determine the usual and ordinary meaning of
    words in a statute.” (Humane Society of U.S. v. Superior Court (2013) 
    214 Cal. App. 4th 1233
    , 1251.) As we have explained in a prior case, relevant dictionary definitions are
    those extant before or at least near in time to the statutory or contractual usage. (See
    
    Alameda, supra
    , 213 Cal.App.4th at p. 1188.)
    9  Although Alameda involved contract language, the contract was authorized by the
    Legislature and later ratified by the People, and therefore carried the force of statutory
    law. (See 
    Alameda, supra
    , 213 Cal.App.4th at p. 1172; see 
    id. at p.
    1186 [contract “by
    virtue of the manner of its confirmation by the people and the Legislature is akin to a
    statute”].)
    19
    Before the enactment of the original statute, diversion meant: “A turning aside or
    altering the natural course of a thing” (1 Bouvier’s Law Dict. (8th ed. 1914), p. 898, col.
    1), “turning of a watercourse or a part of it out of its natural channel” (Ballentine’s Law
    Dict. (2d ed. 1948) p. 391, col. 2, italics added), and “taking water from the channel in
    which it flows” (1 Cal. Digest Words & Phrases (Bancroft-Whitney 1960) p. 531, col. 2,
    italics added).
    Thus the dictionary definitions, although not dispositive, strongly favor the
    Department’s candidate of meaning.
    2. Common law and judicial definitions
    Before the adoption of section 1602, the usage of divert in the context of
    California water law was entirely consistent with the Department’s interpretation, and
    undermines the Farm Bureau’s.
    Leading California water treatises emphasize “ ‘It is immaterial . . . whether the
    water was taken from the river by means of a canal, ditch, flume, or pipe, or by any other
    method.’ It is the fact of diversion, and not the mode, that is material.” 
    (Hutchins, supra
    ,
    Exercise of Appropriative Right, p. 162, fn. omitted; see 1 Rogers & Nichols, Water for
    Cal. (1967) § 172, p. 233 [“riparian owner can divert water . . . in any way he desires as
    long as he does not take more than his reasonable share”]; see 
    id., Appropriative Water
    Rights, §§ 204-206, pp. 294-298 [same rule for appropriators].)
    A statutory definition flowing from a source predating section 1602, Water Code
    section 1706 (Stats. 1943, ch. 368, § 1706, p. 1629), provides: “The person entitled to
    the use of water by virtue of an appropriation . . . may change the point of diversion,
    place of use, or purpose of use if others are not injured by such change . . . .” (Italics
    added.) As the trial court recognized, some cases interpreting this provision involve
    diverting water for ranching or other agricultural purposes. (See, e.g., Barnes v. Hussa
    (2006) 
    136 Cal. App. 4th 1358
    , 1364-1365; Pleasant 
    Valley, supra
    , 61 Cal.App.4th at pp.
    20
    746, 779.) Case law can help define terms, as we have noted in another case involving
    water law. (
    Osborn, supra
    , 116 Cal.App.4th at p. 773.)
    What is more significant about Water Code section 1706 is that equivalent
    language appeared in former Civil Code section 1412, enacted in 1872, and that statute,
    in turn, codified then-extant law. (See Code commrs. note foll. 1 Ann. Civ. Code § 1410
    (1st ed. 1872, Haymond & Burch, commrs.-annotators) p. 403 [citing, e.g., Kidd v. Laird
    (1860) 
    15 Cal. 161
    ]; see 
    Hutchins, supra
    , at pp. 175-177; Barnes v. 
    Hussa, supra
    , 136
    Cal.App.4th at p. 1368, fn. 7; see also 2 Kinney on Irrigation and Water Rights (2d ed.
    1912) § 825, pp. 1448-1449 [“any lawful means” of diversion permitted]; 1 Weil, Water
    Rights in the Western States (3d ed. 1911) § 501, p. 538 [appropriators]; 
    id., § 754,
    pp.
    827-829 [riparians].)
    Consistent with such usage, California courts used the term divert to mean the
    mere taking of water from a channel. (Miller & Lux v. Enterprise Canal Land Co. (1915)
    
    169 Cal. 415
    , 433 [opening headgate “would inevitably divert into the canal water that
    would otherwise pass into the slough”]; see Tulare Irrigation Dist. v. Lindsay-Strathmore
    Irrigation Dist. (1935) 
    3 Cal. 2d 489
    , 519 [pumping underground water described as a
    diversion]; 
    Hutchins, supra
    , p. 249 [“Diversion of the water by raising it over the banks
    of the stream ‘by pump, or other similar appliances’ has been specifically upheld”]; see
    also People v. Glenn-Colusa Irrigation Dist. (1932) 
    127 Cal. App. 30
    , 32 [“diversion . . .
    by means of a battery of pumps located near the head of the canal”].)
    As our Supreme Court has held, discussing riparian rights, “Whatever be the just
    proportion of water to which any riparian proprietor is entitled, that proportion cannot be
    diminished by the fact that in order to utilize it he must raise it from the bed of the stream
    by pumps, or other similar appliances. Every diversion of water from a stream is
    artificial--a disturbance of the natural order of things. A dam or a ditch is as much an
    artificial mechanism as a pump, it may indeed be much more so; and the one alters the
    natural conditions in the same sense that the other does. The right to take the water at all
    21
    is a right to change the ordinary course of nature; and the methods employed, so long as
    their use does not infringe the like and equal rights of others, are immaterial.”
    (Charnock v. Higuerra (1896) 
    111 Cal. 473
    , 480-481, italics added.) This broad meaning
    of diversion has never been changed in California water law. (See Simons v. Inyo Cerro
    Gordo Mining Power Co. (1920) 
    48 Cal. App. 524
    , 537; 62 Cal.Jur.3d (2013) Water,
    § 300, p. 374; id, § 154, p. 209 [riparians]; 
    id., § 215,
    p. 274 [prescriptive rights].)
    This reading of divert is consistent with its usage in a case involving the public
    trust doctrine. As stated by our Supreme Court: “ ‘If the public trust doctrine applies to
    constrain fills which destroy navigation and other public trust uses in navigable waters, it
    should equally apply to constrain the extraction of water that destroys navigation and
    other public interests. Both actions result in the same damage to the public interest.’ ”
    (
    Audubon, supra
    , 33 Cal.3d at pp. 436-437, final italics added, quoting Johnson, Public
    Trust Protection for Stream Flows and Lake Levels (1980) 14 U.C. Davis L.Rev. 233,
    257-258, and also citing the following passage of Dunning, The Significance of
    California’s Public Trust Easement for California Water Rights Law (1980) 14 U.C.
    Davis L.Rev. 357, 359-360: “[I]t is clear that diversions sometimes may interfere with
    navigable waters just as seriously as physical obstacles do and that in such cases the
    public trust easement may logically be invoked to protect the public uses”].)
    Accordingly, the court held “the public trust doctrine . . . protects navigable waters [like
    Mono Lake] from harm caused by diversion of nonnavigable tributaries.” (
    Audubon, supra
    , 33 Cal.3d at p. 437, fn. omitted.) The mere diversion of water from the tributaries
    triggered the public trust doctrine, because such diversion could damage Mono Lake.
    Thus, under the public trust doctrine, as under riparian and appropriative rights rules,
    mere diversion of water--i.e., without changing or obstructing a stream or river--may
    itself be deleterious.
    Thus, the term divert or diversion as used in California water law has always
    applied to the taking of water from a stream or river, and not merely blocking or altering
    22
    the course of the stream or river itself. This long-standing usage was presumably known
    to the Legislature when it considered the 1959 Senate Report, which addressed a bill
    containing different language than that ultimately adopted by the 1961 Legislature and by
    subsequent statutory revisions.
    “When the Legislature enacts language that has received definitive judicial
    construction, we presume that the Legislature was aware of the relevant judicial decisions
    and intended to adopt that construction.” (Foley v. Interactive Data Corp. (1988) 
    47 Cal. 3d 654
    , 675; see Estate of McDill (1975) 
    14 Cal. 3d 831
    , 839.)
    Thus, we conclude the common law usage of divert in the water context does not
    advance but instead refutes the Farm Bureau’s tendered candidate of meaning, that would
    exclude ordinary agricultural pumping. (See, e.g., Phelps v. State Water Resources
    Control Bd. (2007) 
    157 Cal. App. 4th 89
    , 93, 97 [upholding civil penalties for unlawful
    diversion of water for farming purposes, as that term is used in Wat. Code, § 1052, subd.
    (a)].) “The entire history of the origin and development of the doctrine of appropriation
    of water in California, existing alongside the ancient common law concept of riparian
    rights, demonstrates that appropriation of water in the legal sense involves possession of
    the water, evidence[d] by some form of diversion or physical control over it. The courts
    from the very birth of the legal concept of appropriation of water have uniformly
    evidenced the basic common element of possession. Sometimes it is referred to as a
    ‘taking’ of water, ‘diversion,’ or a ‘physical control.’ ” (California Trout, Inc. v. State
    Water Resources Control Bd. (1979) 
    90 Cal. App. 3d 816
    , 819, italics added; see Jurupa
    Ditch Co. v. County of San Bernardino (1967) 
    256 Cal. App. 2d 35
    , 41 [“Water is not
    owned until it is taken in a receptacle by the hand of man, or through works of man
    transferring water from the stream into some facility such as a pond, ditch, flume or
    pipeline” (italics added); cf. Callens v. County of Orange (1954) 
    129 Cal. App. 2d 255
    ,
    23
    259 [flood-control case; “Straightening, widening, or deepening the channel of a stream
    to improve the drainage entails no diversion of the waters”]10.)
    Therefore, it is difficult to conceive that when the Legislature wrote “divert or
    obstruct,” it did not understand that “divert” meant something other than “obstruct,”
    because from time immemorial in California to divert meant to take water by any
    reasonable means that did not injure others with lawful rights to the same water.11
    3. Related Statutory Usages
    In determining the meaning of divert in section 1602, it is also appropriate to
    consider how the Legislature has used that or similar terms in related contexts.
    Water Code section 5100, subdivision (c), adopted just a few years after section
    1602 (see Stats. 1965, ch 1430, § 1, p. 3358), defines diversion within the context of
    10  We note subsequent changes to the rules regarding flood control liability (see Locklin
    v. City of Lafayette (1994) 
    7 Cal. 4th 327
    ; Paterno v. State of California (1999) 
    74 Cal. App. 4th 68
    , 81-85) and cite Callens only to show the common usage of the term
    divert before 1961.
    11  The Farm Bureau cites cases involving liability for water damage, to show divert
    includes physically altering a watercourse, but not extracting water. None of those cases
    pertained to the statute at issue; further, we see nothing in those cases holding that the
    term divert does not encompass mere water extraction. (See Weaver v. Bishop (1988)
    
    206 Cal. App. 3d 1351
    [upholding verdict finding that adding riprap to strengthen creek
    bank was reasonable, although it damaged other property]; Ektelon v. City of San Diego
    (1988) 
    200 Cal. App. 3d 804
    , 809 [alleged unreasonable diversion of floodwaters];
    Youngblood v. City of Los Angeles (1958) 
    160 Cal. App. 2d 481
    , 486-488 [construction of
    revetment channeled storm water onto plaintiff’s land]; Clement v. State Reclamation
    Board (1950) 
    35 Cal. 2d 628
    , 636 [liability for one who “obstructs the natural channel of
    the river”]; Archer v. City of Los Angeles (1941) 
    19 Cal. 2d 19
    , 26 [“there is no diversion
    if surface waters, flowing in no defined channel, are for a reasonable purpose gathered
    together and discharged into the stream that is their natural means of drainage even
    though the stream channel is inadequate to accommodate the increased flow”]; LeBrun v.
    Richards (1930) 
    210 Cal. 308
    , 314-315 [“ ‘one may not obstruct or divert the flow of a
    natural watercourse’ ” but flood waters are “ ‘ “a common enemy against which every
    man has a right to defend himself” ’ ”].) Cases are not authority for propositions not
    considered. (See Hart v. Burnett (1860) 
    15 Cal. 530
    , 598.)
    24
    certain reporting requirements to the Board (see Wat. Code, § 25) to mean “taking water
    by gravity or pumping from a surface stream or subterranean stream flowing through a
    known and definite channel, or other body of surface water, into a canal, pipeline or other
    conduit, and includes impoundment of water in a reservoir.” (Italics added; see Stats.
    2007, ch. 675, § 3, p. 5741 [current version of this statute].) Obviously, pumping water
    out of a surface or subterranean stream need not alter the streambed itself.
    In contrast, Government Code section 40404, subdivision (c), adopted in 1949,
    well before section 1602, authorized local legislative bodies (see Gov. Code, § 34000) to
    condemn property for “[w]idening, straightening, or diverting the channels of streams.”
    (Stats. 1949, ch. 79, § 1, pp. 211-212, italics added.) The qualification that the diversion
    must pertain to the channels of streams shows that the term divert had a broader meaning
    and that the Legislature was aware of that meaning and wanted to limit it: In regards to
    condemnation, it did not intend this statute to apply to diversions of water unless those
    diversions changed the channels of the streams.
    We note with particular interest that a fairly recent statute, enacted in 2012, adds a
    $10,000 civil penalty to deter diversions contravening section 1602 that are made for the
    purpose of facilitating production or cultivation of controlled substances on public lands,
    or while trespassing on private lands. (§ 12025, subd. (a)(1).) In adopting this statute,
    the Legislature in part found, “Many illegal marijuana growsites include water diversion
    with irrigation pipes, . . . illegal damming and water diversion, and pesticides and
    insecticides that are sometimes added directly to streams and ponds.” (Stats. 2012, ch.
    390, § 1(a)(5).) Such “[i]llegal water diversion for the purpose of cultivating marijuana
    poses a direct threat to California’s endangered coho salmon. To prevent their extinction
    from northern California waters, it is imperative that habitat restoration occurs.” (Stats.
    25
    2012, ch. 390, § 1(a)(6).)12 This language shows, consistent with our prior discussion,
    that the Legislature is aware that diversion can be accomplished with pipes and pumps,
    and not merely by changing the streambed or course of a stream.
    These statutes illustrate that the Legislature is aware of the potentially broad
    meaning of divert or diversion, and when it wants to specify a particular form of
    diversion, it does so. The fact that it has never chosen to limit the meaning of divert as
    used in section 1602 is significant. The 2012 statute is particularly illuminating, as it
    strengthens the penalties for violating section 1602, and in doing so discusses the
    deleterious impact of one type of diversion (illegal marijuana grows) on anadromous fish,
    recognizing that merely dewatering a stream using irrigation pipes can be a diversion that
    harms such fish. While the 2012 Legislature cannot speak with the voice of the 1961
    Legislature, we find the following rule to be most apt: “ ‘[W]here the Legislature amends
    a statute without altering a consistent and long-standing judicial interpretation of its
    operative language, courts generally indulge in a presumption that the Legislature has
    ratified that interpretation.’ ” (People v. Anderson (2002) 
    28 Cal. 4th 767
    , 780.)13
    12 The trial court found that the Legislature declared the coho salmon to be a threatened
    species in 2003, and an endangered species in 2005.
    13 We need not discuss in any detail other, later-adopted statutes referenced by the
    parties or amici curiae. These statutes, too, show the Legislature knows what divert
    means and how to limit its broad meaning when desired. (See, e.g., Pen. Code, § 498,
    subd. (a)(5) [“change the intended course or path of electricity, gas, or water”]; Pub.
    Resources Code, § 5093.56 [referencing “the planning or construction of a dam,
    reservoir, diversion, or other water impoundment facility that could have an adverse
    effect on the free-flowing condition and natural character of” designated waters]; Wat.
    Code App. § 97-39, subd. (a); Stats. 1971, ch. 308, § 1, p. 636 [a person must notify a
    particular water agency if the person “intends to divert or cause to be diverted any surface
    water”].)
    26
    4. Legislative History
    The trial court examined documents purportedly bearing on the legislative intent
    behind the words of the statute, both prior to the 1961 enactment, including the 1959
    Senate Report referenced by both the 1973 Attorney General opinion and by the Weaver
    decision, and documents bearing on subsequent amendatory statutes.
    Identifying and resolving statutory ambiguity are two separate interpretive steps.
    “[I]t is the language of the statute itself that has successfully braved the legislative
    gauntlet. It is that language which has been lobbied for, lobbied against, studied,
    proposed, drafted, restudied, redrafted, voted on in committee, amended, reamended,
    analyzed, reanalyzed, voted on by two houses of the Legislature, sent to a conference
    committee, and, after perhaps more lobbying, debate and analysis, finally signed ‘into
    law’ by the Governor. The same care and scrutiny does not befall the committee reports,
    caucus analyses, authors’ statements, legislative counsel digests and other documents
    which make up a statute’s ‘legislative history.’ ” (Halbert’s Lumber, Inc. v. Lucky
    Stores, Inc. (1992) 
    6 Cal. App. 4th 1233
    , 1238; see Wasatch Property Management v.
    Degrate (2005) 
    35 Cal. 4th 1111
    , 1117-1118.) Even assuming statutory ambiguity has
    been identified, “[w]e rely on the legislative history of an ambiguous statute as
    dispositive only when that history is itself unambiguous.” (Medical Board v. Superior
    Court (2003) 
    111 Cal. App. 4th 163
    , 179; see J.A. Jones Construction Co. v. Superior
    Court (1994) 
    27 Cal. App. 4th 1568
    , 1578 [“courts can get it wrong when what they have
    before them is a motley collection of authors’ statements, committee reports, internal
    memoranda and lobbyist letters. . . . In light of these factors, the wisest course is to rely
    on legislative history only when that history itself is unambiguous”].)
    In this case, the 1959 Senate Report referred to proposals that never passed, and
    that explicitly referenced mining activities. True, that Senate Report discussed the same
    problem addressed by section 1602, but it at best dimly illuminates the meaning of that
    statute or any statute, for that matter, when its language was not on the table.
    27
    It is true, as the trial court found, that the Senate Report detailed the deleterious
    effects of aggregate mining and streambed alteration on anadromous fish. We note that a
    separate statute passed in 1961 precluded using vacuum or suction dredge mining absent
    a permit, which the Department’s predecessor would issue upon determining “that such
    operation will not be deleterious to fish.” (Former § 5653; Stats. 1961, ch. 1816, § 1, p.
    3864; see now §§ 5653 et seq.) There is no doubt that the lingering effects of
    California’s mining history continued to affect fish, and that fact was well understood by
    the 1961 Legislature.14
    But contrary to the trial court’s view, the fact that gravel extraction deemed
    harmful to anadromous fish motivated the adoption of the relevant statutes does not
    import into the word divert any requirement that such diversion be linked to gravel
    extraction, or streambed alteration: The Legislature properly could find the damage done
    by the Gold Rush required strong remedial measures extending to all forms of diversion.
    The trial court found it significant that section 1602 does not refer to use of water,
    as did two sister-state statutes. These statutes were described in a report by Ralph N.
    Kleps, then the Legislative Counsel, included within the Senate Report, with the opinion
    that California “could enact similar legislation.” According to his summary, an Alaska
    statute required notification for a “hydraulic project” or use of “any equipment that would
    use, divert, obstruct, pollute or change the natural flow or level of any river lake or
    stream” and Kleps stated the “Washington law is, in general, similar to the Alaska
    law.”15 However, those statutes applied to equipment that would divert the natural flow
    14  Further, that same year the Legislature declared a state policy “that preservation of
    fish and wildlife be provided for in connection with the construction of state water
    projects.” (Stats. 1961, ch. 867, §1, p. 2274; see Wat. Code, § 11900.)
    15 See State v. Crown Zellerbach Corp. (1979) 92 Wash.2d 894, 896, footnote 1 [602
    P.2d. 1172, 1173, footnote 1] (quoting a version of the relevant Washington law).
    28
    of any stream. A pump that removes water would fall within “any equipment” under
    such a statute. The fact use does not appear in the later-adopted California statute is of no
    moment. (See 
    Alameda, supra
    , 213 Cal.App.4th at p. 1179 [“Nor does the fact that
    language could be clearer make it ambiguous”].)
    In the trial court, the Farm Bureau argued the Legislature would not have intended
    to impact mere water extractions--without alterations of streambeds--pursuant to water
    rights without leaving some trace of such issue in the legislative record. (See, e.g., In re
    Christian S. (1994) 
    7 Cal. 4th 768
    , 782 [“We are not persuaded the Legislature would
    have silently, or at best obscurely, decided so important and controversial a public policy
    matter”]; Ailanto Properties, Inc. v. City of Half Moon Bay (2006) 
    142 Cal. App. 4th 572
    ,
    589 [“The Legislature ‘does not, one might say, hide elephants in mouseholes’ ”].) But
    the Legislature did not act silently on this subject: It acted by passing a statute using the
    word divert, which had a clear, preexisting meaning in the context of water law. That it
    did not explicitly address the then well-settled meaning of divert and the ensuing
    consequences of its actions creates no ambiguity in the word divert itself. (See In re
    Christian S., at p. 782 [“The depth of the debate is the domain of the Legislature”].)
    Thus the legislative documents considered by the trial court do not raise a latent
    ambiguity in section 1602.16
    5. Administrative Interpretation
    The Farm Bureau claims the Department has already administratively interpreted
    the provision in a manner favoring the Farm Bureau. We disagree.
    We accept the Farm Bureau’s general point that contemporaneous administrative
    interpretation of a statute is entitled to deference, but this deference arises (if at all) only
    16 We deny the Farm Bureau’s request to take judicial notice of further legislative
    documents, both because they were not presented to the trial court (People v. Preslie
    (1977) 
    70 Cal. App. 3d 486
    , 493) and because we find them unnecessary to consider.
    29
    when a statute is ambiguous, and is stronger where the agency has adopted a formal
    regulation interpreting a statute falling within its area of responsibility. (See Yamaha
    Corp. of America v. State Bd. of Equalization (1998) 
    19 Cal. 4th 1
    , 7-8.) Although we
    find no linguistic ambiguity, and the Farm Bureau has not pointed to any formal
    regulatory interpretation, we briefly address the Farm Bureau’s claims on this point.
    First, the Farm Bureau points to a June 16, 1961, letter the Department sent,
    urging the Governor to sign the bill enacting section 1602. Such executive department
    letters contained in enrolled bill reports are not probative of the intent of the Legislature,
    but under existing precedent must be deemed judicially noticeable. (Kaufman & Broad
    Communities, Inc. v. Performance Plastering, Inc. (2005) 
    133 Cal. App. 4th 26
    , 40-42.)
    However, the Farm Bureau misinterprets the letter. The quoted portion pertains to
    government projects that may “divert, obstruct or change the natural flow or bed of any
    stream,” which refers to former section 1601, inapplicable herein. The portion of the
    letter addressing former section 1602, applicable to private projects, merely states the bill
    requires, “Notification of department by private persons and opportunity for the
    department to make recommendations on stream work.” This is hardly a thoughtful
    administrative interpretation, it is a brief summary of the bill. Moreover, the Legislative
    Analyst (whose views are both judicially noticeable and at times persuasive indications of
    the Legislature’s views, see Kaufman, at p. 32) cogently summarized the bill on May 4,
    1961, as covering “projects for diverting, obstructing or otherwise changing the natural
    flow” (italics added) of any river or stream, and emphasized that it was “basically a
    measure aimed at improving and preserving the spawning areas for salmon.” Change in
    the natural flow encompasses dewatering of spawning reaches, which jeopardizes the
    salmon’s ability to spawn.
    Second, the Farm Bureau points to a Biennial Report to the Governor from the
    Department covering the period July 1, 1960, through June 30, 1962. This document
    gives a one-paragraph general description of the then-“new” statute, in which it is stated--
    30
    without analysis--that the notification requirement is applicable to “alteration of stream or
    lake beds.” This report was designed to give an overview of the operations of the entire
    Department over a two-year period, and did not purport to give an authoritative
    interpretation of the new statute, merely a thumbnail sketch of it.
    Third, the Farm Bureau points to the Department’s view of the 2003 amendments
    to the relevant sections, in an enrolled bill report. The document references “Streambed
    Alteration Agreements” a term added to the statute in the 2003 amendments, and
    references what it called “the current streambed statutes.” (See Stats. 2003, ch. 736, § 2,
    p. 5523, adopting current § 1601, subd. (a) [“ ‘Agreement’ means a lake or streambed
    alteration agreement”].) But the same document accurately states that the then-current
    version of the statute “requires any person to notify the Department before commencing
    any activity that will substantially divert or obstruct the natural flow or substantially
    change the bed, channel, or bank of any river, stream, or lake.” (Italics added.) This
    shows the Department did not view the statute as applicable only to activities that alter
    the streambed itself, despite the use of the shorthand descriptor “streambed alteration
    agreement.”
    Finally, and more generally, the Farm Bureau asserts the Department has abruptly
    changed its policy regarding section 1602, by seeking to enforce it in a way it has never
    done before. This was the subject of conflicting evidence in the trial court. For purposes
    of this appeal, we construe that evidence in the light favorable to the trial court’s ruling,
    which rejected the Department’s evidence that it had tried to enforce the broad view of
    section 1602 before. But past non-enforcement does not necessarily reflect a formal
    administrative interpretation precluding enforcement, but could instead reflect the
    exercise of prosecutorial discretion or limited resources, as the Department argued in the
    trial court, in addition to arguing it had exercised discretion to enforce the statute broadly.
    One relevant executive report states the Department “generally uses these powers . . .
    where streambed alteration is involved, often with respect to very minor streams.” (A.
    31
    Schneider, Legal Aspects of Instream Water Uses in California (Governor’s Com. to
    Review Cal. Water Rights Law, Staff Paper No. 6, Jan. 1978), p. 98, italics added.)17
    This suggests that its powers are greater and it does not always use such powers only
    when streambed alteration has occurred.
    More importantly, taking it as true--as the trial court found--that the Department
    has not previously enforced section 1602 absent streambed alteration, that is an
    insufficient basis on which to find the statute precludes it from doing so. In the face of
    extreme drought and piscatorial peril, the Department now wishes to employ the full
    measure of the law, to substantial dewatering of streams absent physical alteration to the
    streambeds. Its previous lack of enforcement does not rewrite the statute. (See Bank of
    Italy v. Johnson (1926) 
    200 Cal. 1
    , 15 [agency head “may not by the adoption of any rule
    of policy or procedure so circumscribe or curtail the exercise of his discretion under the
    statute as to prevent the free and untrammeled exercise thereof in every case, for an
    attempt to do so would be for him to arrogate to himself a legislative function”].) “Mere
    failure to act . . . does not constitute an administrative construction.” (Estate of Madison
    (1945) 
    26 Cal. 2d 453
    , 463; see Feduniak v. California Coastal Com. (2007) 
    148 Cal. App. 4th 1346
    , 1369 [“the mere failure to enforce the law, without more, will not
    estop the government from subsequently enforcing it”].)
    In short, we see nothing in the Department’s prior construction or enforcement of
    the statute that raises any latent ambiguity of meaning in the language of the statute. (See
    
    Alameda, supra
    , 213 Cal.App.4th at pp. 1188-1189.)18
    17 This was part of a series of reports drafted in response to the 1976-1977 drought, then
    viewed as “the worst recorded dry spell in California history.” (M. Archibald,
    Appropriative Water Rights in California; Background and Issues (Governor’s Com. To
    Review Cal. Water Rights Law, Staff Paper No. 1, May 1977), p. 1.)
    18 The trial court also found: “Under the plain meaning rule, the act of diverting water
    pursuant to a water right is within the scope of § 1602 if the diversion would substantially
    32
    6. Conclusion
    Given the above discussion, interpreting the statute as posited by the Farm Bureau
    effectively reads the word divert out of the statute, contrary to the rule “ ‘that in
    attempting to ascertain the legislative intention effect should be given, whenever
    possible, to the statute as a whole and to every word and clause thereof, leaving no part or
    provision useless or deprived of meaning.’ ” 
    (Rank, supra
    , 51 Cal.3d at p. 18.) The
    Farm Bureau’s candidate of meaning does not plausibly account for the language of the
    statute, therefore no linguistic ambiguity has been demonstrated.
    Thus, taking water out of its natural flow for agricultural purposes is a diversion of
    such water, whether or not the streambed itself is altered to accomplish the taking.
    II
    Absurd Results and the Constitutional Doubt Doctrine
    The trial court posited that the Department’s interpretation would lead to absurd
    results because, “Following [the Department’s] argument and applying a literal
    interpretation, the preservation of fish and wildlife is the only factor to be considered in
    regulating [a] water right.” The trial court separately expressed the view that the
    adversely affect the fish and wildlife dependent upon the stream system. However, the
    definition would require that each diversion be examined on a case-by-case basis,
    something that was not contemplated in the ‘Stopher criteria’ of watershed-wide
    declaration advanced by the DFG. Therefore the plain language interpretation does not
    completely address the issue of ambiguity.” (Italics added.) This is not a correct
    conclusion. The fact that the aborted Stopher criteria may have departed from the need
    to determine on a case-by-case basis whether any given planned diversion was substantial
    does not raise any doubt about the constitutionality of the statute. Instead, it appears to
    reflect a misunderstanding of the statute by a Department employee. Further, the
    Department never applied the Stopher criteria, as the trial court found. The Department
    now concedes that a substantial diversion as used in section 1602 cannot equate to any
    diversion. Instead, as the 1973 Attorney General opinion concluded, what is a substantial
    diversion within the meaning of section 1602 depends on the facts of each case. (See 56
    
    Ops.Cal.Atty.Gen., supra
    , at pp. 364-365.) This should have mooted any concerns about
    over-zealous enforcement.
    33
    Department’s interpretation might impair vested property rights, and applied the rule that
    statutes should be construed so as to avoid constitutional doubts. (See Long 
    Valley, supra
    , 25 Cal.3d at pp. 349-350.) These two different legal findings overlap to the extent
    they invoke water rights as a basis of decision, and both hinge on the existence of a
    statutory ambiguity, as we now explain.
    A. Constitutional Doubt
    The constitutional doubt canon applies if and only if the statute is “realistically
    susceptible of two interpretations and the interpretation to be rejected must raise grave
    and doubtful constitutional questions.” (People v. Anderson (1987) 
    43 Cal. 3d 1104
    ,
    1146.) It “is a tool for choosing between competing plausible interpretations of a
    statutory text, resting on the reasonable presumption that Congress [or, mutatis mutandis,
    the Legislature] did not intend the alternative which raises serious constitutional doubts.”
    (Clark v. Martinez (2005) 
    543 U.S. 371
    , 381 [
    160 L. Ed. 2d 734
    , 747], italics added.)
    Thus the trial court erred in even considering the canon, because there was no
    ambiguity to resolve. Further, applying section 1602 to agricultural users who
    substantially divert water--without altering the streambed--does not impair their vested
    water rights in any way. Section 1602 is merely a notification statute, triggering
    arbitration and adjudication procedures in the event of disagreement, inter alia, as to
    whether a substantial diversion has occurred or will occur. In rejecting a related claim we
    have held that “[t]he requirement . . . that Murrison notify [the Department] of his intent
    to substantially alter or divert Big Creek furthers the state’s substantial interest in the
    protection of the state’s fish and wildlife. This statutory requirement is inherent in the
    state’s sovereign power to protect its wildlife and Murrison’s water rights are subject to
    these powers. A water right, whether it predates or postdates 1914 is not exempt from
    reasonable regulation.” (People v. Murrison (2002) 
    101 Cal. App. 4th 349
    , 361; see
    
    Rutherford, supra
    , 188 Cal.App.3d at pp. 1276-1279 [rejecting claim that notification
    requirements are vague both facially and as applied]; see also Howard v. County of San
    34
    Diego (2010) 
    184 Cal. App. 4th 1422
    , 1430 [administrative exhaustion case; “ ‘claim that
    the application of government regulations effects a taking of a property interest is not ripe
    until the government entity charged with implementing the regulations has reached a final
    decision regarding the application of the regulations to the property at issue’ ”].) We
    found Murrison’s takings claim was unripe because the injunction and attendant civil
    penalties in that case merely enforced his duty to provide notice and did not of itself
    affect his property rights. (Murrison, at pp. 354, 362-363; see Rutherford, at p. 1280, fn.
    4.) “The mere imposition of a notice requirement does not impact Murrison’s ability to
    exercise his claimed water right. As a result, the provisions of the Fish and Game Code
    which could affect the amount to be diverted were never applied by [the Department].
    Murrison’s challenge to [the Department’s] ability to restrict the amount of water he may
    take must wait until he notifies [the Department] of his intent to divert the stream and his
    water rights have been limited in some manner.” (Murrison, at p. 362; see 
    id. at p.
    363
    [“the arbitration panel provided for in the statute could have rejected [the Department’s]
    requirements and imposed no restrictions . . . . Only if . . . restrictions are imposed may
    we determine whether a compensable taking has occurred”].)19
    Thus, section 1602, which helps ensure the continued beneficial use of
    California’s water; does not of itself effect a taking under the Fifth Amendment of the
    United States Constitution or under article I, section 19 of the California Constitution.
    (Cf. B. C. Cotton, Inc. v. Voss (1995) 
    33 Cal. App. 4th 929
    , 949-950 [applying
    constitutional doubt canon where a contrary interpretation would raise a takings
    problem].) If a given diverter’s usage is found to be substantial, requiring compliance
    19 Amici curiae Pacific Legal Foundation and California Cattlemen’s Association
    contend the notification process is burdensome to the point where it becomes a taking.
    This view is echoed by the Farm Bureau’s brief responding to all amici curiae briefs. We
    find this argument, like Murrison’s, is unripe.
    35
    with mitigation measures or halting such usage would not be a taking, but a proper
    exercise of regulatory police powers. (See People ex rel. State Water Resources Control
    Bd. v. Forni (1976) 
    54 Cal. App. 3d 743
    , 753 (Forni); Walston, The Public Trust Doctrine
    in the Water Rights Context: The Wrong Environmental Remedy (1982) 22 Santa Clara
    L.Rev. 63, 85-92 [reallocation of use under public trust doctrine and reasonable use
    provision of the California Constitution does not result in a compensable taking].)20
    B. Absurd Results
    We have summarized the absurd result rule as follows: “[I]f a statute is
    susceptible to more than one interpretation, we must adopt the reasonable meaning and
    reject that which would lead to an unjust and absurd result.” (People v. Catelli (1991)
    
    223 Cal. App. 3d 1434
    , 1448, italics added.) This exception “should be used most
    sparingly by the judiciary and only in extreme cases else we violate the separation of
    powers principle of government. (Cal. Const., art. III, § 3.) We do not sit as a ‘super-
    legislature.’ ” (Unzueta v. Ocean View School Dist. (1992) 
    6 Cal. App. 4th 1689
    , 1698.)
    “Each time the judiciary utilizes the ‘absurd result’ rule, a little piece is stripped from the
    written rule of law and confidence in legislative enactments is lessened. Retired Justice
    Macklin Fleming describes this as the ‘. . . devaluation of written law and of legislative
    authority of popular assemblies.’ ” (Id. at p. 1699.)
    Again, we emphasize that because no ambiguity is presented by the statute, the
    absurd result rule cannot be used to rewrite it, even if the effects of its application are
    perceived as unfair--or even absurd--by some.
    20 In Young v. State Water Resources Control Bd. (2013) 
    219 Cal. App. 4th 397
    , we
    upheld the Board’s right to administratively adjudicate, subject to the judicial review,
    whether an unlawful diversion of water occurred, within the meaning of Water Code
    section 1831, regardless of whether the diverter claimed riparian or pre-1914
    appropriative rights, although we acknowledged the Board lacked jurisdiction to regulate
    such rights. (Young, at pp. 400, 404-407.)
    36
    Quite obviously, a severe drought, which has the effect of further damaging the
    habitat of an endangered fish species, must be part of the factual matrix considered in
    determining what is a reasonable use of the water--water which belongs to the people,
    and only becomes the property of users--riparian or appropriative--after it is lawfully
    taken from the river or stream. Past practices, no matter how long-standing, do not
    change current reality. (See 
    Audubon, supra
    , 33 Cal.3d at p. 447 [public trust doctrine
    case; “In exercising its sovereign power to allocate water resources in the public interest,
    the state is not confined by past allocation decisions which may be incorrect in light of
    current knowledge or inconsistent with current needs”]; United States v. State Water
    Resources Control Bd. (1986) 
    182 Cal. App. 3d 82
    , 142; see 
    id. at p.
    150 [“the Board
    unquestionably possessed legal authority under the public trust doctrine to exercise
    supervision over appropriators in order to protect fish and wildlife”] (United States).)
    Contrary to the parade-of-horribles posited by the Farm Bureau and some allied
    amici curiae, and evidently assumed by the trial court, if a different policy is desired, the
    Legislature may rewrite the statute. (See Osborn v. Hertz 
    Corp., supra
    , 205 Cal.App.3d
    at p. 711.) In this connection we note that there is also no discussion--and could not have
    been any discussion--in the Senate Report of the consequences of the current drought on
    the viability of anadromous fish, vis à vis diversions of water. As we indicated ante,
    “ ‘ “that a statute can be applied in situations not expressly anticipated by [the
    Legislature] does not demonstrate ambiguity. It demonstrates breadth.” ’ ” (Estate of
    
    Earley, supra
    , 173 Cal.App.4th at p. 376, italics added.) Balancing the needs of fish and
    agriculture is a matter well within the Legislature’s competence, and if this notification
    statute is viewed by that body to be too onerous to farmers and ranchers, it can change the
    statute to balance water usage needs as it deems appropriate.
    37
    Thus, we see nothing absurd in applying the plain meaning of the statute.21
    III
    Regulatory Overlap
    The trial court also concluded that applying what it conceded was the plain
    meaning of section 1602 would delegate to the Department the authority to adjudicate
    water rights that is now vested in the Board, and also allow the Department to prioritize
    beneficial uses of water contrary to the Board’s powers. However, the Board, appearing
    in this court via amicus briefing, disavows any such conflict with the Department. Amici
    curiae Law Professors, too, support the Department’s and Board’s view that the two
    agencies act together, not in conflict, regarding issues over overlapping concern. We
    agree that applying the plain meaning of section 1602 does not blur the lines of authority
    between these agencies.
    The Farm Bureau’s point appears to be not that the Department could not have
    been given the power that the plain meaning of section 1602 confers as we have
    interpreted it, but rather that it was not given that power, and our interpretation of section
    1602 would upset the division of power the Legislature has established between the
    Board and Department.
    First, the Legislature is free to distribute power to state subdivisions, and if it
    chooses to take power from the Board and give it to the Department, it may. (See, e.g.,
    Star-Kist Foods, Inc. v. County of Los Angeles (1986) 
    42 Cal. 3d 1
    , 6; Mallon v. City of
    Long Beach (1955) 
    44 Cal. 2d 199
    , 209.)
    21  The Farm Bureau’s claim that because the statute imposes criminal liability, it ought
    to be construed leniently fares no better. That interpretive rule, too, applies where and
    only where a statute is first found to be ambiguous, as a tie-breaker between candidates of
    meaning standing in relative equipoise inter sese. (See People v. Cornett (2012) 
    53 Cal. 4th 1261
    , 1271; People v. Manzo (2012) 
    53 Cal. 4th 880
    , 889.) Here, the interpretive
    candidates do not stand in relative equipoise, as we have explained at length, ante.
    38
    Second, as the Department and Board emphasize, they have always had the
    statutory authority and duty to work cooperatively on issues of common concern.
    “The Department is obligated to protect the fish and wildlife resources of the state
    ([] §§ 1700, 5500 et seq.) which are the property of the people of the state ([] § 1600),
    who have ‘the right to fish upon and from’ the state’s public lands and waters (state
    Const., art. I, § 25).” (Fullerton v. State Water Resources Control Bd. (1979) 
    90 Cal. App. 3d 590
    , 593, fn. 1 (Fullerton).) “The Legislature has entrusted the supervision
    and protection of this valuable resource of the state to the [Department].” (Ferrante v.
    Fish & Game Commission (1946) 
    29 Cal. 2d 365
    , 374 [referring to Department’s
    predecessor].)
    The Board is charged “with maximum flexibility to consider the competing
    demands of flows for piscatorial purposes and diversions for agricultural, domestic,
    municipal or other uses” when considering water appropriation claims, and the Board
    relies on the Department to advise it regarding matters within the Department’s expertise,
    including fish. 
    (Fullerton, supra
    , 90 Cal.App.3d at pp. 603-604.) The Board has the duty
    and expertise to administer water appropriations in the public interest, which includes all
    beneficial uses, including preserving and enhancing fish and wildlife resources. (See
    Wat. Code, §§ 1243 [fish and wildlife resources are a beneficial use], 1253 [Board shall
    allow appropriation of water “for beneficial purposes” that “in its judgment will best
    develop, conserve, and utilize in the public interest the water”], 13000 [“activities and
    factors which may affect the quality of the waters of the state shall be regulated to attain
    the highest water quality which is reasonable”], 13050, subd. (f) [beneficial water uses
    include “preservation and enhancement of fish”]; United 
    States, supra
    , 182 Cal.App.3d at
    pp. 103, 109-110, 116, 126, 130; 
    Fullerton, supra
    , 90 Cal.App.3d at pp. 603-604.) The
    Board may act against riparians, too, who unreasonably use water. (United 
    States, supra
    ,
    182 Cal.App.3d at pp. 140-142; 
    Forni, supra
    , 
    54 Cal. App. 3d 743
    ; see Wat. Code, § 275.)
    39
    It has “ ‘broad,’ ‘open-ended,’ ‘expansive’ authority to undertake comprehensive
    planning and allocation of water resources.” (
    Audubon, supra
    , 33 Cal.3d at p. 449.)
    Water Code section 1243, which declares preservation of fish as a beneficial use
    of water when the Board considers requests for water appropriations, recognizes the
    overlapping expertise of the Board and the Department, partly providing: “The board
    shall notify the [Department] of any application for a permit to appropriate water. The
    [Department] shall recommend the amounts of water, if any, required for the preservation
    and enhancement of fish and wildlife resources and shall report its findings to the board.”
    The Board itself, appearing as an amicus on behalf of the Department, states:
    “The notification requirement Section 1602 establishes for substantial diversions does not
    conflict with the [Board’s] administration of water rights. In fact, Section 1602 can assist
    the Board in carrying out its responsibilities to protect public trust resources where
    feasible. Whether a subsequent agreement reached pursuant to Section 1602 conflicts
    with water right laws or a decision of the [Board] is entirely hypothetical. Even then,
    limitations on the exercise of a water right are consistent with California law.” Under the
    Board’s view, the Department’s actions in no way impair the Board’s duty and power to
    adjudicate water rights issues. The Board emphasizes that inter-agency accommodations
    can be made, and any actual conflict could be resolved on an as-applied basis. We agree.
    The trial court also concluded that applying the plain meaning would mean the
    Department “is guaranteed the appropriation of a minimum in-stream flow for the
    preservation of fish and wildlife, contrary to law” because such appropriation would
    bypass Board approval. The Farm Bureau defends the view that applying section 1602 to
    mere dewatering will in effect grant the Department power to compel minimum in-stream
    flows. We disagree with this view.
    We have previously rejected a claim that a different statute which we construed to
    require a minimum in-stream flow to preserve fish would be unconstitutional. (See
    California 
    Trout, supra
    , 207 Cal.App.3d at pp. 622-625.) It has also been held that the
    40
    Department cannot acquire an appropriative right to a minimum in-stream flow to
    preserve fish, for lack of a physical taking of the water, as required to perfect an
    appropriative right. (See 
    Fullerton, supra
    , 90 Cal.App.3d at pp. 598-605.) These cases
    describe two different legal rules. Here, the Department seeks no appropriative rights
    but merely seeks to exercise the statutory mechanism for determining whether substantial
    diversions have occurred that may harm fish. This desire is consistent with the portion of
    Fullerton emphasizing the Department’s role in informing the Board of piscatorial needs,
    before new appropriations are made. 
    (Fullerton, supra
    , 90 Cal.App.3d at pp. 600-601.)
    Accordingly, the Department’s plain meaning interpretation of section 1602 does
    not intrude on the Board’s powers or duties.
    CONCLUSION
    A claim of statutory ambiguity must be resolved by a hierarchy of steps. Only if
    two candidates of meaning each plausibly account for the statutory language can it be
    said that a statute is ambiguous. Although extrinsic evidence may reveal a latent
    ambiguity, such ambiguity must reside in the language of the statute. Those of us tasked
    with statutory interpretation must be mindful of the presumption that the Legislature, as
    the Department concludes its briefing, “says what it means and means what it says.”
    (People v. 
    Snook, supra
    , 16 Cal 4th at p. 1215 [“We presume the legislature meant what
    it said”]; cf. Seuss, Horton Hatches the Egg (1940), passim [“I meant what I said[,] and I
    said what I meant”].)
