    REVIEW of a decision of the Court of Appeals.                   Reversed and
    cause remanded.
    ¶1     DAVID T. PROSSER, J.        This case, involving a dispute
    about the water levels on Lake Koshkonong, presents fundamental
    questions about the authority of the Wisconsin Department of
    Natural     Resources     (the   DNR),   and   the     criteria       it    uses     in
    No.         2008AP1523
    regulating      the    level     of    water   in     navigable      waters        that    are
    affected by dams.
    ¶2        Wisconsin     Stat.     § 31.02(1)1          authorizes       the    DNR     to
    regulate the level and flow of water in the navigable waters of
    Wisconsin.           The   DNR   may    order        benchmarks      designating          "the
    maximum level of water that may be impounded and the lowest
    level of water that may be maintained by any dam."                               
    Wis. Stat. § 31.02
    (1).          The statute       provides       that    the   DNR     may     regulate
    water levels         "in the interest          of    public    rights       in     navigable
    waters    or    to    promote     safety       and    protect       life,     health      and
    property."      
    Id.
    ¶3        The dispute here results from a 2003 petition (the
    Petition)      by    the   Rock-Koshkonong           Lake    District,       Rock     River-
    Koshkonong Association, Inc., and Lake Koshkonong Recreational2
    Association, Inc. (collectively, the District)3 to raise the DNR-
    1
    All subsequent references to the Wisconsin Statutes are to
    the 2009-10 version unless otherwise indicated.
    2
    The complaint initiating judicial review of the DNR
    decision by the Rock County Circuit Court named "Lake Koshkonong
    Recreational Association, Inc." as one of the petitioners.
    However, the proper name of the entity is "Lake Koshkonong
    Recreation   Association,   Inc."  as   indicated   by Wisconsin
    Department    of   Financial   Institution   corporate  records.
    Therefore, all further references to the association will use
    its proper name.
    3
    The Rock-Koshkonong Lake District filed the Petition in
    2003 to raise the water levels on the lake.      After the DNR
    rejected the Petition, Rock River-Koshkonong Association, Inc.
    and Lake    Koshkonong   Recreation Association,  Inc.  jointly
    petitioned with the Rock-Koshkonong Lake District for a
    contested case hearing.    For the sake of simplicity, we will
    refer to all three entities as the District throughout this
    opinion, unless otherwise noted.
    2
    No.         2008AP1523
    designated water levels of Lake Koshkonong.                             The DNR rejected
    the Petition, and its denial was affirmed by an administrative
    law judge (ALJ) in a contested case hearing by the Rock County
    Circuit Court, Daniel T. Dillon, Judge, and by the court of
    appeals.      See Rock-Koshkonong Lake Dist. v. DNR, 
    2011 WI App 115
    , 
    336 Wis. 2d 677
    , 
    803 N.W.2d 853
    .                        The ALJ's decision was
    adopted as the decision of the DNR.
    ¶4   We are presented with four issues.
    ¶5   First,      what   level    of       deference,       if    any,     should     be
    accorded to the DNR's conclusions of law under the circumstances
    of this case?
    ¶6   Second, did the DNR exceed its authority in making a
    water level determination under 
    Wis. Stat. § 31.02
    (1) "in the
    interest of public rights in navigable waters," by considering
    the impact of water levels on private wetlands that are adjacent
    to Lake Koshkonong and located above the ordinary high water
    mark?
    ¶7     Third, did the DNR exceed its authority in making a
    water level determination under 
    Wis. Stat. § 31.02
    (1) "in the
    interest of public rights in navigable waters" by considering
    wetland water quality standards in Wis. Admin. Code § NR 103?
    ¶8     Fourth,      did   the     DNR       err   in   making       a     water     level
    determination under 
    Wis. Stat. § 31.02
    (1) by excluding evidence
    and     refusing    to    consider      the        impacts    of        water    levels      on
    residential        property     values,           business     income,          and     public
    revenue?
    ¶9     We conclude the following:
    3
    No.       2008AP1523
    ¶10    The DNR's conclusions of law are subject to de novo
    review because         the    DNR's water          level   order       under    
    Wis. Stat. § 31.02
    (1) is heavily influenced by the DNR's interpretation of
    the scope of its own powers, its interpretation of the Wisconsin
    Constitution,         its    disputed      interpretation         of     the    statute      it
    utilized, and its reliance upon statutes and rules outside of
    Wis. Stat. ch. 31.
    ¶11    The    DNR     properly         considered     the        impact        of   the
    Petition's proposed water levels on public and private wetlands
    in   and      adjacent       to     Lake    Koshkonong.            However,        the      DNR
    inappropriately        relied       on   the    public     trust       doctrine    for      its
    authority to protect non-navigable land and non-navigable water
    above the ordinary high water mark.                   The DNR has broad statutory
    authority grounded in the state's police power to protect non-
    navigable      wetlands       and    other      non-navigable          water    resources.
    Thus,    the    DNR    may    consider         the   water    level       impact       on   all
    adjacent property under 
    Wis. Stat. § 31.02
    (1).
    ¶12    The DNR was entitled to consider the water quality
    standards in Wis. Admin. Code § NR 103, promulgated under Wis.
    Stat. ch. 281, when making a Wis. Stat.§ 31.02(1) water level
    determination.         By statute, the DNR is responsible for writing
    and enforcing wetland water quality standards in this state.
    Accordingly, it         would be         unreasonable       for    the    DNR     to    ignore
    statutes and its own administrative rules when making a water
    level determination affecting wetlands.                      Therefore, the DNR may
    consider § NR 103 water quality standards when making a water
    level    determination        under      
    Wis. Stat. § 31.02
    (1)       that       affects
    4
    No.       2008AP1523
    wetlands and may apply these standards when appropriate after
    weighing    the    factors    in   the   statute.     However,      
    Wis. Stat. § 281.92
     suggests that the DNR is not required to apply ch. 281
    standards in making a determination under 
    Wis. Stat. § 31.02
    because ch. 31 is excepted from the provisions of ch. 281.
    ¶13    The    DNR    erroneously    excluded   most    testimony      on    the
    economic impact of lower water levels in Lake Koshkonong on the
    residents, businesses, and tax bases adjacent to and near Lake
    Koshkonong.       This evidence was relevant to the DNR's decision-
    making under 
    Wis. Stat. § 31.02
    (1).           Although the DNR is granted
    substantial discretion in its decision-making under the statute,
    it must consider all probative evidence when its decision is
    likely to favor some interests but adversely affect others.                       In
    this case, the DNR's exclusion of most economic evidence was
    inconsistent with its acceptance of competing economic evidence
    that helped sustain its water level decision.
    ¶14    We remand this case to the circuit court for further
    proceedings consistent with this opinion.
    I. FACTS AND PROCEDURAL HISTORY
    ¶15    We begin the statement of facts and procedural history
    with an examination of the Rock River, Lake Koshkonong, and the
    Indianford Dam.          Next, we explain the purpose of ch. 31 of the
    Wisconsin     Statutes,      the   history   of     water   levels      on      Lake
    Koshkonong, and the Petition.            We then summarize the contested
    case hearing and the resulting decision, In the Matter of the
    Review of the Water Level Decision for Lake Koshkonong and the
    Indianford Dam on the Rock River in Rock County, Wisconsin, Case
    5
    No.        2008AP1523
    No. 3-SC-2003-28-3100LR, (DNR, Dec. 1, 2006) [hereinafter the
    Decision], which was adopted by the DNR.                      Finally, we lay out
    the procedural history of the District's appeal.
    A. The Rock River
    ¶16     The    Rock    River   originates        in    Dodge      County    near
    Theresa, just south of the Fond du Lac County line.                       It flows in
    a southerly, then southwesterly direction, passing through such
    Wisconsin communities as Watertown, Fort Atkinson, Janesville,
    and Beloit before entering Illinois.                    The Rock River empties
    into the Mississippi River            near       Rock   Island,   Illinois.          Its
    total length is nearly 300 miles.
    ¶17     The mouth of the Rock River flows into Lake Koshkonong
    about four miles downstream from the City of Fort Atkinson in
    Jefferson County.            The outlet of the lake, which funnels water
    back into the narrow channel of the Rock River, is situated
    about six miles upstream from the Indianford Dam in Rock County.
    B. Lake Koshkonong
    ¶18     Lake    Koshkonong,    the       sixth   largest   inland      lake    in
    Wisconsin, is a natural widening of the Rock River4 located in
    Jefferson, Rock, and Dane Counties.                 While Lake Koshkonong has a
    wide       surface    area   (approximately       10,460     acres),     it   is   quite
    shallow.       At the current targeted water level ordered by the DNR
    in 1991, Lake Koshkonong's average depth is only five feet and
    4
    Lake Koshkonong and the Rock River are navigable waters
    under Wisconsin law.      See 
    Wis. Stat. § 30.10
    (1) and (2)
    (declarations of navigability for lakes and streams).
    6
    No.        2008AP1523
    its maximum depth is only seven feet.5                           The topography of the
    shoreline is gently sloped in such a way that water levels of
    one to two feet can extend quite far into the lake.
    ¶19       Lake Koshkonong has 27 miles of shoreline.                            Ten miles
    of     shoreline         have    been     developed        for   residential            and    some
    commercial         use.         Approximately        2,788    residential          parcels      are
    located       within      a     half-mile   of       the   lake,      with   more       than    600
    riparian parcels adjacent to the lake.
    ¶20       Lake    Koshkonong        contains         12.4      miles       of     wetland
    shoreline.          Among the largest wetlands in and adjacent to the
    lake        are   Koshkonong       Creek    (278      acres      of    shallow      marsh       and
    floodplain forest); Krumps Creek (335 acres of shallow marsh);
    Mud Lake (921 acres of shallow marsh); Otter Creek (334 acres of
    shallow marsh and floodplain forest); Thiebeau Marsh (494 acres
    of shallow marsh, shrub, and meadow); and the state-owned and
    DNR-managed         Koshkonong          Wildlife      Area    (715      acres      of     shallow
    marsh, shrub, and meadow known as an area of "special natural
    resource interest" under Wis. Admin. Code § NR 103.04).                                       These
    areas       and    all    of     Lake    Koshkonong        are     replete      with      diverse
    species of wildlife and vegetation.                           The ALJ found that the
    5
    Around the time of statehood, Lake Koshkonong had a very
    different appearance than it does today.   Visiting the area in
    July 1850, Dr. I.A. Lapham wrote, "The water is from 4 to 12
    feet deep.    At the time of our visit, . . . wild rice was
    growing abundantly over almost its whole surface, giving it more
    the appearance of a meadow than a lake."    W.H. (Bill) Rodgers,
    Early History of Lake Koshkonong 1 (Mar. 21, 1961) (unpublished
    manuscript) (on file with Hoard Historical Museum, Fort
    Atkinson, Wis.).
    7
    No.    2008AP1523
    wetland shoreline has eroded since 1940.                   "The reduced frequency
    of low water conditions during the summer and the increase in
    the average summer water levels . . . account for the loss of
    wetlands over the past 70 years."
    C. The Indianford Dam
    ¶21    The Indianford Dam affects water levels on the Rock
    River and Lake Koshkonong.              In 1843 the Wisconsin territorial
    legislature authorized Clouden and Luke Stoughton to build the
    original dam; however, the Stoughtons did not construct the dam
    until       after    March    1851,    when       the   state   legislature    again
    authorized construction.          Around 1917 the dam was reconstructed,
    which       raised    water   levels    on       Lake   Koshkonong.      The   Rock-
    Koshkonong Lake District, which was created in 1999, took over
    ownership and operation of the dam from Rock County in 2004.6
    ¶22       The dam fell into general disrepair in the 1960s until
    it was rehabilitated in 2002.                    Because of this disrepair, the
    dam's operation was compromised and it failed to regulate water
    levels on Lake Koshkonong——to conform with the target levels set
    by the DNR——for much of the time between the late 1960s until
    about 2002.          As a result, water levels on Lake Koshkonong since
    1965 have almost always exceeded the current target level of
    776.20 feet above mean sea level (msl),7 as the following chart
    from the Decision illustrates:
    6
    Rock County took over ownership of the dam in December
    1965 from the Wisconsin Power & Light Co.

    ¶23    The "statistically significant upward trend in average
    water levels" on Lake Koshkonong from 1932 to 2003 was partly
    attributable to the "diminished operating range of the wicket
    gates" on the dam before its 2002 repairs, as well as debris on
    the trash racks of the dam that impeded flowage.
    D. Wis. Stat. Chapter 31 and the District's Petition
    ¶24    Chapter 31 of the Wisconsin Statutes grants the DNR
    authority      to     regulate    dams   and    bridges   affecting        navigable
    waters in the state.         The DNR may regulate and control the level
    and flow of water in all navigable waters "in the interest of
    9
    No.      2008AP1523
    public     rights    in   navigable          waters      or    to    promote     safety     and
    protect    life,     health      and    property."             
    Wis. Stat. § 31.02
    (1).
    Section 31.02(2) states that the "construction, operation, [and]
    maintenance . . . of dams in navigable waters shall be subject
    to   the    supervision          of    the    [DNR]       and       to    the    orders     and
    regulations of the [DNR]."               Thus, a dam operator must petition
    the DNR8 for an order if it wishes to raise or lower the water
    levels of a navigable body of water in a manner inconsistent
    with a previously existing order.
    ¶25     The     Wisconsin         Railroad          Commission         (the    Railroad
    Commission)        issued     the      first       water       level      order     for    the
    Indianford Dam in 1919.                The next order was not issued until
    1982, when the DNR, on its own motion, issued another order
    reestablishing water levels pursuant to 
    Wis. Stat. § 31.02
    (1).
    The DNR determined that the existing order was inadequate to
    control the water levels of Lake Koshkonong.
    ¶26     However,       the       1982     order       was      appealed       by     three
    individuals, two lake-based recreation clubs, a property owners
    association,       and    Rock    County.          The    Jefferson        County       Circuit
    Court's decision affirming the 1982 order was appealed to the
    court of appeals, which remanded to the DNR to hold a hearing
    before issuing any water level order.                         A compromise between the

    The legislature originally delegated authority to issue
    water level orders to the Railroad Commission.    § 3, ch. 380,
    Laws of 1915 (creating Wis. Stat. ch. 69m. § 1596——2.1. (1915)).
    The Public Service Commission and then the DNR became the
    successor agencies responsible for issuing water level orders
    under Wis. Stat. ch. 31.
    10
    No.      2008AP1523
    DNR and the parties resulted in a 1991 water level order.                     The
    1991 order left the 1982 order largely intact, raising slightly
    the   minimum   lake   elevation   in    the   winter   and    eliminating      a
    flashboard9 requirement.10
    ¶27   In 2002, after the rehabilitation of the Indianford
    Dam restored full operating capability to the dam's gates, the
    water levels on Lake Koshkonong began to reflect more closely
    the levels set by the 1991 order.          As a result, water levels on
    the lake dropped below recorded levels since the 1930s.                        On
    April 21, 2003, the District11 petitioned the DNR, pursuant to
    
    Wis. Stat. § 31.02
    (1), to amend the 1991 order.                     The District
    contended   that   the   1991   order    was   "not   consistent       with   the
    public interest" because lower water levels on Lake Koshkonong
    led to severe restrictions on recreational boating and in many
    cases "piers must be extended far from shore to reach navigable
    water depths."     In addition, the District expressed concern for
    the effect that the winter drawdown in the 1991 order had on
    shore erosion, plants, and animal species.

    A flashboard is a "board or structure of boards extending
    above a dam to increase its capacity."     The American Heritage
    Dictionary of the English Language 691 (3d ed. 1992).
    10
    The DNR amended the 1991 order in 2004 to reflect the
    change in ownership of the Indianford Dam from Rock County to
    the Rock-Koshkonong Lake District.    The 2004 amendment made no
    substantive changes to the 1991 water order.
    11
    Rock-Koshkonong Lake District was established by Rock
    County in 1999, pursuant to 
    Wis. Stat. §§ 33.24
     and 33.37(1),
    "to undertake a program of . . . protection and rehabilitation
    for Lake Koshkonong." More than 4,000 parcels of land in Rock,
    Jefferson, and Dane Counties make up the Rock-Koshkonong Lake
    District.

    ¶29     In 2003 and 2004 the DNR conducted an environmental
    assessment (EA) of the Petition's proposed water level order to
    determine whether an environmental impact statement (EIS) would
    be needed.     The DNR completed a draft EA in December 2004, after
    which a public hearing was held in January 2005 for comment on
    the findings.       The DNR certified the EA as complete in March
    2005 and determined that an EIS would not be necessary.

    denying the Petition, keeping the summer maximum water level at

    ¶31    Shortly      thereafter,    the     District      filed     a   joint
    petition for a contested case hearing of the DNR's denial of the
    Petition. The DNR granted the request and then filed a hearing
    request     with    the   Department    of    Administration,         Division   of
    Hearings and Appeals (DHA).13
    E. The Contested Case and Decision
    ¶32   The     ten-day    contested      case   hearing    on     the   DNR's
    proposed order commenced on March 29–30, 2006, in Jefferson, and
    continued in Madison at the DHA offices on April 3–5 and 10–14.
    During the Jefferson hearing, members of the public provided
    sworn testimony and statements on how the Petition would affect
    their community and personal interests, while representatives of
    the parties to the contested case provided expert testimony.
    ¶33   As part of its pre-filed direct expert testimony, the
    DNR   sought   to    show     the   adverse    impact   that    the    District's
    proposed water level increase would have on adjacent wetlands
    13
    Rock River-Koshkonong Association, Inc. (RRKA) and Lake
    Koshkonong Recreation Association, Inc. (LKRA) joined in the
    petition for a contested case hearing.     RRKA is comprised of
    more than 300 members, including riparian business owners on
    Lake Koshkonong and the Rock River.   LKRA is an association of
    approximately 38 individual and business members who rely on
    Lake Koshkonong and the Rock River for business, recreation, and
    tourism.
    The Intervenors in this case——Lake Koshkonong Wetland

    and water quality in Lake Koshkonong and the Rock River.                               One
    DNR expert testified in detail how raising the water levels of
    Lake    Koshkonong      would    "result     in    secondary        and       cumulative
    adverse impacts to wetlands."               These adverse impacts included
    continued     erosion      of   wetlands;     loss    of        wildlife      and    fish
    habitat;     loss     of    vegetation       and     floodplain         forest;        and
    eventually     reduced      recreational      opportunities             for    hunters,
    fishermen, trappers, and birdwatchers.                Furthermore, while Lake
    Koshkonong has lost a great deal of wetlands over the years and
    will continue to lose wetlands, raising water levels in the lake
    as the District proposes would exacerbate the losses.                         Other DNR
    experts echoed these conclusions.14                Overall, the DNR experts
    testified to the importance           of     making    sure      the    proposed       DNR
    water level order satisfied the wetland water quality standards
    in Wis. Admin. Code § NR 103.
    ¶34   Expert     testimony     on     behalf        of     the      Intervenors
    concurred with the DNR testimony on adverse impacts to wetlands
    and wetland water quality if the District's proposed water level
    order were implemented.
    ¶35   The      Jefferson     County     Farm     Drainage          Board       also
    presented testimony on the adverse impact of higher water levels
    on Lake Koshkonong: any increase in water levels would lead to
    backups in the drainage district upstream from the lake, causing
    lands to stay flooded longer and increase crop losses.                              Dennis
    14
    The District and the DNR also devoted a significant
    amount of testimony to disputing the validity of water level
    modeling by the District.
    14
    No.        2008AP1523
    Kutz,       an     agricultural        landowner        in    the       drainage         district,
    indicated in pre-filed direct testimony that his yield on corn
    could "be reduced downward from 180 to 100 bushels per acre at a
    cost of $200–$300 per acre.                     Other farmers would likely have
    similar losses."
    ¶36        The District presented evidence at the contested case
    hearing, through expert testimony, on modeling data to predict
    water levels under the Petition, along with the probable effect
    of    the        District's     water     level       order        on    navigation,         water
    quality, and fish and wildlife habitat.
    ¶37        The    District       also     presented          evidence         of   economic
    impacts resulting from, and anticipating, lower water levels on
    the   lake.            Land    use    planner     and      real     estate       analyst      John
    Stockham testified that a reduction in historical water levels
    on Lake Koshkonong would have adverse effects on property values
    and   commercial          activity      related       to     the    lake.           Essentially,
    Stockham testified that lower water levels than those observed
    before the Indianford Dam was fully operational in 2002 would
    result in decreased waterfront usage; loss of the ability to use
    existing          piers       for     boating,        swimming,         and      other       water
    activities; loss of access to shoreline for boats; and reduced
    areas of navigability.                Reduced usable water access would, over
    time, have          an adverse impact            on    property         values      around    Lake
    Koshkonong; this reduced value would be reflected in the slower
    rate of increase for Lake Koshkonong property values compared to
    "lakefront          property         values     in     general          in    south       central
    15
    No.         2008AP1523
    Wisconsin."15         Stockham testified that lake-based businesses also
    would        suffer    losses    from       reduced      water      levels.          The    most
    affected       businesses       would       be    lakefront    marinas,       taverns,       and
    restaurants that          depend       on    boaters     and    tourists       for    a large
    portion of their revenue.                Even businesses in nearby communities
    who    cater     to    lake-related          activity       would    suffer     from       water
    levels on Lake Koshkonong reduced from their historical levels.
    In    addition,       reduced    water        access    and    property       values       would
    result in a loss of tax base for local taxing jurisdictions.
    ¶38     Dr.     Russell       Kashian,      an   economics      professor       at    the
    University of Wisconsin-Whitewater, also provided testimony on
    behalf of the District on the economic impact of lowering a
    lake's       water     level.         Using       various     economic    methodologies,
    Kashian concluded that a reduction in historical water levels on
    Lake Koshkonong would result in a negative economic impact in
    two areas: property values and a reduced rate of appreciation of
    those values, and economic activity in communities surrounding
    the lake.
    ¶39     In     regard    to    lake       property    values,     Kashian       posited
    that lower water levels mean a greater distance between the lake
    home and the shore, and that the increased distance would result
    15
    Testimony   on  behalf  of   the   Intervenors   by   Linn
    Duesterbeck,   a  real  estate   appraiser,   contradicted   John
    Stockham's assertions on the reduced rate of property value
    increases around Lake Koshkonong since 2002.        Duesterbeck's
    property value testimony was later excluded by the ALJ, along
    with the testimony of John Stockham and Dr. Russell Kashian, as
    outside the scope of a 
    Wis. Stat. § 31.02
    (1) water level
    determination.
    16
    No.      2008AP1523
    in lower property value; Kashian also testified that property
    value is adversely affected by a decrease in shoreline length.
    The reduction in lake water levels, both real and perceived by
    potential property buyers, would lead to a softening of demand
    for lake property and a consequent reduction in prices, along
    with a slower appreciation in property value over time.                          Kashian
    cited numerous studies on the economic impact of reduced lake
    water levels to support his conclusions.                      Kashian concluded that
    the     DNR's    proposed       water    level       order     would    endanger        Lake
    Koshkonong property values.
    ¶40    Finally, Kashian testified on the adverse effects that
    reduced lake water levels would have on economic activity in the
    local    community.         Assuming       a       three-foot    reduction      in      Lake
    Koshkonong water levels, Kashian testified that "real estate and
    service sector businesses would witness a decline of $9 million
    in    gross     sales    that    support       an    estimated    150    total     jobs."
    Moreover, "local retail businesses would witness a decline of
    $5.25 million in gross retail sales that support an estimated
    200 total jobs."
    ¶41     Public testimony on the commercial effects of adhering
    to the DNR's 1991 water level order echoed the District's expert
    testimony.        A     campground      and    marina    owner    testified        to    the
    "huge"    economic       impact    that       lake-based      tourism    has     on     area
    business and property values, as well as the negative impact
    that lower water levels would                  have.         Several    other   business
    owners    on    Lake     Koshkonong      testified       that    current     low      water
    levels required the installation of piers of up to 300 feet in
    17
    No.      2008AP1523
    length        in   order    to   accommodate       customers      who     access     their
    businesses by boat.
    F. The Decision's Findings of Facts and Analysis
    ¶42    On December 1, 2006, the ALJ, William S. Coleman, Jr.,
    issued a meticulous, comprehensive Decision affirming the DNR's
    proposed order rejecting the Petition.                     The Decision contained
    120 findings of fact,16 which, after laying out the history and
    statistics on Lake Koshkonong and the Indianford Dam, may be
    briefly summarized as follows:
    1.        Historical        Water    Levels    on     Lake     Koshkonong——Water
    levels rose from 1932 to 2003, and this was due in part to the
    defective Indianford Dam.                Consequently, summer water levels on
    the lake were above the DNR's target levels every year but two
    from 1965 to 2003.
    2.        Wetlands——The high historical water levels on the lake
    have eroded shoreline wetlands around the lake.                               The reduced
    frequency of low water conditions in the lake have contributed
    to this loss of wetland.             Other than the state-owned Koshkonong
    Wildlife Area, the findings of fact do not explicitly identify
    how much of the wetlands are publicly owned, or what portion of
    the wetlands are above the ordinary high water mark.
    3.        Water       Quality——Higher       water     levels    have       caused   a
    "degraded          turbid    algae-dominant        water     condition"         in    Lake
    Koshkonong.          An increase in water levels would likely further

    The District does not dispute any of the 120 findings of
    fact.
    18
    No.          2008AP1523
    degrade water quality in the lake.17                  Higher water levels would
    lead to additional loss of wetlands, which would affect the lake
    system's ability to slow flood and storm waters, and "filter
    nutrients,       sediments      and    other     pollutants,"       such     that        more
    pollutants would be carried downstream.
    4.     The Ordinary High Water Mark18 (OHWM)——The OHWM on Lake
    Koshkonong       increased      from   1979     to   2001,    due   in     part    to    the
    diminished capacity of the Indianford Dam to properly regulate
    water        levels.      The    DNR    considered      778.11       msl    to      be    "a
    representative OHWM" for purposes of evaluating the Petition.
    The higher water levels under the Petition could result in a
    higher OHWM.
    5.        Erosion    Protection       from      Riprap    Structures19——Higher
    water levels on the lake would likely overwhelm existing riprap
    structures       that    protect      wetland    shoreline.         These    structures
    would more quickly degrade and result in expensive fortification
    of the structures.           In any event, the riparian wetlands would

    According to the findings of fact, Lake Koshkonong is
    likely to remain in a degraded condition regardless of whether
    the DNR's proposed order or the Petition is adopted.

    "By ordinary high-water mark is meant the point on the
    bank or shore up to which the presence and action of the water
    is so continuous as to leave a distinct mark either by erosion,
    destruction   of   terrestrial  vegetation,  or   other  easily
    recognized characteristic." Diana Shooting Club v. Husting,

    Riprap is a "loose assemblage of broken stones erected in
    water or on soft ground as a foundation." The American Heritage
    Dictionary of the English Language 1556 (3d ed. 1992).    Riprap
    is used to protect shorelines from water or ice erosion.

    No.       2008AP1523
    not be protected from increased wave action and would continue
    to erode.
    6.      Wildlife——Past and continued higher water levels would
    adversely     impact     habitats     for    herptiles       and    bird     species.
    Continued loss of wetland would result in loss of wildlife and
    fish habitat in and around Lake Koshkonong.
    7.      Winter Drawdown——The findings of fact contain numerous
    pros and cons of maintaining the winter drawdown of the lake
    levels    (under   the      DNR's   proposed   order)       and    eliminating       the
    winter    drawdown     under   the   Petition.        The    findings       generally
    point to adverse impacts on wetlands, wildlife, water quality,
    and riprap structures if the winter drawdown were eliminated.
    8.      Agricultural Drainage——Higher water levels will cause
    backups in a drainage district upstream from Lake Koshkonong.
    Slower    drainage     would    cause   farmland      to    be     flooded    longer,
    resulting in delays in planting and smaller crop yields.
    9.      Public    Access——The      shallow,   sloping         waters    of   Lake
    Koshkonong    make     it   difficult    for   most    recreational          boats   to
    utilize public boat ramps on the lake under either the DNR's
    proposed water level order or the District's proposed higher
    levels.     However, there are a number of boat access points along
    the Rock River near the lake that have sufficient depth for
    recreational boats.
    10.    Riparian Access——Most riparian property owners favor
    raising the lake's water levels so that they may shorten their
    piers.     Boat lifts and shore stations also could be maintained
    20
    No.       2008AP1523
    closer to shore if the District's proposed higher water levels
    were implemented.
    11.    Natural Scenic Beauty——Fuller "pool levels" are more
    aesthetically pleasing to riparian property owners than exposed
    lake beds.      However, some riparians value the beauty of the
    wetlands that would be lost with higher water levels.
    12.    Navigability——Raising water levels on the lake would
    increase the surface area of the lake by up to 63 acres and
    mitigate existing navigational obstacles in the lake.20
    13.    The 
    Wis. Stat. § 31.02
    (1)      Standard——The     findings    of
    fact concluded with, "The net negative effects of the proposed
    higher water levels far outweigh the enhancements to navigation
    and access."    Thus,
    [a]llowing increased water levels as proposed by the
    District would be inconsistent with the interest of
    public rights in Lake Koshkonong and the Rock River,
    and would not serve to protect life, health or
    property.   Public safety may be marginally promoted
    with increased water levels, but the water levels
    specified in the DNR's 2005 order do not pose undue
    risks to public safety.

    contested    case   hearing   to   admitting    evidence   related    to    the
    20
    No one appears to have challenged any of the ALJ's
    findings of fact.    We note, however, that the ALJ found that
    Lake Koshkonong has a surface area of approximately 10,460
    acres, after the water levels in Lake Koshkonong were lowered to
    conform to the DNR's 1991 order.     The figure 10,460 acres is
    identical to the figure used by the DNR in a 1971 Wisconsin
    Conservation   Bulletin.      Shoreland  is   Vulnerable,   Wis.

    effect of water levels on real estate values, business income,
    and   public       revenues.         The      Decision       sustained        the   DNR's
    objections,       citing    Wisconsin's       Environmental        Decade,      Inc.    v.
    DNR, 
    115 Wis. 2d 381
    , 404, 
    340 N.W.2d 722
     (1983), and asserting
    that "[s]econdary or indirect economic impacts of a water level
    determination do not bear on the statutory standard set forth in
    section     31.02(1)."           Therefore,     the    ALJ    struck     Stockham      and
    Kashian's economic testimony on behalf of the District, along
    with all related exhibits, as secondary economic impacts outside
    the scope of the statute.21             The Decision did consider riparian
    access, which the ALJ said "comprehends at least one component
    of these asserted secondary impacts."                  The Decision acknowledged
    that riparian owners' "diminished utility and enjoyment of their
    property     [resulting      from     lower     water       levels] . . . doubtless
    reduces the value of that property to them."
    ¶44    The    Decision       noted   that       the    DNR   was     required     to
    balance     and    accommodate      conflicting        interests       when    making   a
    water level determination and that the DNR had done that here.
    Furthermore,       the     DNR     "evaluated     the        proposed      water    level
    increase against the appropriate regulatory standards, including
    chapter NR 103, Wis. Admin. Code."
    21
    In a contested case hearing, a hearing examiner "shall
    not be bound by common law or statutory rules of evidence. The
    agency or hearing examiner shall admit all testimony having
    reasonable probative value, but shall exclude immaterial,
    irrelevant or unduly repetitious testimony or evidence that is
    inadmissible under s. 901.05." 
    Wis. Stat. § 227.45
    (1).
    22
    No.     2008AP1523
    ¶45    Thus, the Decision closes with a conclusion of law
    that   "the       DNR's    decision      [to    reject      the       District's    proposed
    higher water levels] . . . is necessary to protect the public
    rights       in    navigable       waters       and      reasonably         balances       and
    accommodates public and private rights, the promotion of safety,
    and the protection of life, health, and property."
    ¶46    The DNR adopted the Decision as its own, by operation
    of 
    Wis. Stat. § 227.46
    (3)(a) (2003–04) and Wis. Admin. Code § NR
    2.155(1) (Sept. 2004).
    G. The District's Appeal
    ¶47    Following the Decision,                 the    District      petitioned      for
    review   by       the     Rock    County    Circuit         Court      under     
    Wis. Stat. § 227.53
    .         The District contended that the Decision erroneously
    interpreted "public rights in navigable waters" and the phrase
    "protect . . . property."                The        District      argued    that    the    DNR
    improperly        expanded       its   consideration             of   "public     rights    in
    navigable waters" to include private wetlands and that the DNR
    improperly considered wetland water quality standards in Wis.
    Admin. Code § NR 103, as promulgated under Wis. Stat. ch. 281.
    The District further argued that it was improper for the DNR to
    categorically           exclude    all     evidence         of    economic       effects    on
    property in its Decision because, by doing so, it misinterpreted
    the          mandate         in          
    Wis. Stat. § 31.02
    (1)          to
    "protect . . . property."                However, the circuit court affirmed
    the Decision, concluding that the DNR's interpretation of the
    statutes was reasonable and that the Decision was supported by
    substantial evidence.
    23
    No.          2008AP1523
    ¶48    The District appealed to the court of appeals, which
    certified the District's appeal to this court on the issue of
    "ambiguity"       in    
    Wis. Stat. § 31.02
    (1)         related       to     the     phrase
    "protect . . . property."               This court denied the certification
    request.
    ¶49     The court of appeals then issued an opinion affirming
    the     DNR's     Decision,         this        time    holding       that        
    Wis. Stat. § 31.02
    (1), including its "protect . . . property" language, was
    "unambiguous."            Rock-Koshkonong            Lake    Dist.,    
    336 Wis. 2d 677
    ,
    ¶47.      First,       the    court    of       appeals      reasoned       that     when       the
    legislature       wants      the    DNR     to       consider   property           values       and
    economic effects in its decision-making, "it does so in clear,
    unambiguous language."              
    Id.,
     ¶42 (citing statutes).                    Second, the
    court of appeals concluded that if the DNR were required to
    consider economic factors when making a determination under 
    Wis. Stat. § 31.02
    (1)       to      "protect . . . property,"                     such        an
    interpretation "would have no logical stopping point."                                         Id.,
    ¶43.      Finally,      the    court       of    appeals     looked     to       this     court's
    interpretation         of    similar      statutory         language    in        City    of    New
    Lisbon v. Harebo, 
    224 Wis. 66
    , 
    271 N.W. 659
     (1937), for the
    proposition        that       protection         of     property       is        "limited        to
    protection        of    real       property          from    hydrologic           events       like
    flooding."       Id., ¶45.
    ¶50    The court of appeals decision also held that the DNR's
    consideration of the impact of water levels on adjacent wetlands
    and § NR 103 water quality standards was reasonable.                                 The court
    of appeals determined these considerations to be consistent with
    24
    No.      2008AP1523
    "the very resources [the DNR] has been assigned to protect" and
    that the DNR is not restricted to considerations below the OHWM.
    Id., ¶¶52–53.        The court of appeals also concluded that the DNR
    has a responsibility to protect water quality standards in this
    state, and to disregard that duty when making a water level
    determination under 
    Wis. Stat. § 31.02
    (1) would be absurd.                              Id.,
    ¶56.
    ¶51   The District petitioned this court for review, which
    we granted on February 23, 2012.
    II. DISCUSSION
    A. Standard of Review
    ¶52   This    court      normally       provides       a   separate      section    on
    "standard of review" before proceeding to its legal analysis.
    In this case, the standard of review is itself an issue, namely,
    whether the court should give deference to the DNR's conclusions
    of law.
    ¶53   When a party appeals to the court of appeals or seeks
    review in this court "from a circuit court order reviewing an
    agency decision," the appellate court reviews the decision of
    the agency, not the decision of the circuit court.                             Lake Beulah

    293 Wis. 2d 1
    , 
    717 N.W.2d 166
    ).
    ¶54   In Hilton, the court examined the standard of review
    that    should      be   applied     to    an        ALJ    decision     that    had    been
    expressly     adopted        by     the        DNR     pursuant         to     
    Wis. Stat. § 227.46
    (3)(a).          The court concluded that "because the DNR has
    25
    No.      2008AP1523
    expressly adopted the ALJ decision, the ALJ decision should be
    afforded the same deference afforded the agency."                            Hilton, 
    293 Wis. 2d 1
    , ¶14.
    ¶55   In   this    case,      the    Decision       contains      120     specific
    findings of fact.         The District does not challenge any of these
    findings.     If it did challenge any of the findings of fact, the
    court would apply a substantial evidence standard.                           See 
    id.,
     ¶16
    (citing Borsellino v. DNR, 
    2000 WI App 27
    , ¶7, 
    232 Wis. 2d 430
    ,
    
    606 N.W.2d 255
    ).
    ¶56   In this case, the Decision contains four conclusions
    of law grounded in the facts.                    However, the District asserts
    that the DNR exceeded the scope of its authority under 
    Wis. Stat. § 31.02
    (1) by focusing on the protection of public and
    private wetlands above the OHWM; misinterpreted the mandate to
    "protect . . . property"          in    § 31.02(1);        and     excluded      relevant
    evidence that should have been considered under the statute.
    The District also asserts that the DNR improperly considered the
    standards in Wis. Admin. Code § NR 103 in making its water level
    determination under § 31.02(1).
    ¶57   These assertions          involve     issues     of      agency    procedure
    and agency interpretation of law that are treated separately as
    questions of law.
    ¶58   Agency      determinations          involving       questions      of   law,
    including     interpretation         and     application         of     statutes,     are
    reviewable by this court under 
    Wis. Stat. § 227.57

    set aside or modify the agency action if it finds that the
    agency has erroneously interpreted a provision of law."
    ¶59    While statutory interpretation is normally a question
    of law determined independently by a court, a court may give an
    agency's interpretation of a statute great weight deference,22 or
    due     weight    deference,23   or   no    deference.24     Racine    Harley-

    22
    Great weight deference is             appropriately   applied     to an
    agency's legal conclusions where:
    (1) the agency was charged by the legislature
    with the duty of administering the statute; (2) the
    interpretation of the statute is one of long-
    standing; (3) the agency employed its expertise or
    specialized knowledge in forming the interpretation;
    and (4) the agency's interpretation will provide
    uniformity and consistency in the application of the
    statute.

    Due weight deference is applied when "the agency has some
    experience in an area, but has not developed the expertise which
    necessarily places it in a better position to make judgments
    regarding the interpretation of the statute than a court."

    As a general rule, a reviewing court accords an agency no
    deference when the agency has decided an issue of first
    impression, when an agency lacks experience or expertise in
    deciding a legal issue, or when an agency has taken inconsistent
    positions on a legal issue. UFE, Inc. v. LIRC,

    accepts the agency interpretation without a critical eye.                                    The
    court itself must always interpret the statute to determine the
    reasonableness of the agency interpretation.                            Only reasonable
    agency interpretations are given any deference."                             Racine Harley-
    Davidson, 
    292 Wis. 2d 549
    , ¶15.
    ¶60    Here the DNR is charged by the legislature with the
    duty of administering 
    Wis. Stat. § 31.02
    (1), and it brought to
    its enforcement of the statute a great deal of expertise and
    specialized knowledge.                However, the DNR's interpretation of the
    statute is not long-standing with respect to some of the issues
    before this court, and, as will be seen, its interpretation is
    not   likely      to     be    uniform    and       consistent    in    its        application
    because     of    the     diverse       factual       circumstances          that     will    be
    presented.            Thus,    the DNR's       conclusions       of    law    in     statutory
    interpretation are not entitled to great weight deference.
    ¶61    Another factor works against deference.                            "The nature
    and   scope       of    an     agency's        powers    are     issues       of     statutory

    ¶62     In this case, the DNR is at odds with the District
    over the scope of the agency's power.                     As will be seen, the DNR
    has given new interpretations to both the Wisconsin Constitution
    (Article IX, Section 1) and Wisconsin Statutes, disregarded some
    past decisions of this court, and acted inconsistently with some
    of    its     own     prior    positions.        Under    these   circumstances,      we
    afford no deference to the DNR's interpretation and application
    of 
    Wis. Stat. § 31.02
    (1) and consider the legal issues presented
    de novo.25
    ¶63     The DNR concluded that the economic impacts of lower
    water        levels    on     residential    and    business      property    are    not
    relevant in making a water level determination, despite language
    in      
    Wis. Stat. § 31.02
    (1)         authorizing       the     DNR      to
    25
    Wisconsin Stat. § 227.57(8) provides in part:
    The court shall reverse or remand the case to the
    agency if it finds that the agency's exercise of
    discretion   is    outside   the  range  of   discretion
    delegated to the agency by law; is inconsistent with
    an agency rule, an officially stated agency policy or
    a prior agency practice, if deviation therefrom is not
    explained to the satisfaction of the court by the
    agency;   or    is    otherwise  in   violation   of   a
    constitutional or statutory provision . . . .
    This statute implicates the scope of the DNR's authority as well
    as the agency's past decisions and policy.          It provides
    additional authority for not affording deference to the DNR in
    this matter.

    "protect . . . property."               As will be discussed later in this
    opinion,       categorically         excluding      these    economic       factors         from
    consideration in a water level determination under § 31.02(1) is
    not reasonable.           Cf. Racine Harley-Davidson, 
    292 Wis. 2d 549
    ,
    ¶15 (stating that only reasonable agency interpretations receive
    deference).
    ¶64     Thus,    we      afford       no      deference       to        the        DNR's
    interpretation and application of 
    Wis. Stat. § 31.02
    (1) in this
    case.
    B. The DNR'S Consideration of Impacts on Wetlands
    Adjacent to Navigable Waters
    ¶65    The District contends that the DNR, in making a water
    level determination under 
    Wis. Stat. § 31.02
    (1) "in the interest
    of public rights in navigable waters," exceeded its authority
    when it considered impacts on private wetlands adjacent to Lake
    Koshkonong       that    are    above       the    OHWM.     The    District          is    also
    concerned about the application of the public trust doctrine to
    any     wetlands     that      are    not    navigable       in    fact     unless         those
    wetlands are below the OHWM.                       The District asserts that the
    DNR's    position       significantly         expands      the    scope    of    the       DNR's
    public trust jurisdiction.
    ¶66      The      Decision            explains        the       decision-maker's
    understanding of the applicable law.                    In his Discussion section,
    the ALJ wrote:
    "Public rights" in the state's public trust

    ¶67    This       paragraph     cites          the   public      trust        doctrine       as
    authority for the DNR to regulate wetlands and near shorelands,
    wildlife habitat, and scenic beauty.
    ¶68    The DNR's brief to this court confirms this position:
    1.        "Wetlands      in    and      adjacent         to   navigable        waters
    have long been included in public rights to navigable waters
    because of their special relationship to navigable waters."
    2.        "[P]ublic rights in wetlands 'adjacent to or near
    navigable waters' are public rights in, not beyond, navigable
    waters."
    3.        "If   petitioners          were      correct        that      the    public
    trust     does        not      extend        to     privately           owned     non-navigable
    lands . . . then the shoreland zoning law fails, too."
    4.        "[P]ublic      rights         embrace      all      wetlands         in     or
    adjacent to navigable waters, privately or publicly owned, above
    or below the OHWM."
    ¶69       In    evaluating         the       District's        concerns          about    these
    claims,       it    is     necessary         to   examine         the    constitutional             and
    statutory directives associated with public rights in navigable
    waters    and       the     wetlands     adjacent            to   them,      along      with       this
    court's interpretation of these directives.

    The state relies on several sources of authority to achieve this

    ¶71    Article IX, Section 1 of the Wisconsin Constitution

    such rivers or lakes shall form a common boundary to
    the state and any other state or territory now or
    hereafter to be formed, and bounded by the same; and
    the river Mississippi and the navigable waters leading
    into the Mississippi and St. Lawrence, and the
    carrying places between the same, shall be common
    highways and forever free, as well to the inhabitants
    of the state as to the citizens of the United States,

    ¶73   Because the public trust doctrine is rooted in Article
    IX,   Section 1,    however,     it    is   important       to    understand        its
    history     and   its   core    principles     so        that    it     is    properly
    interpreted.      There is no better place to start than Justice
    George Currie's scholarly analysis of the doctrine in Muench v.
    Public Service Commission, 
    261 Wis. 492
    , 
    53 N.W.2d 514
     (1952):
    After   the  Revolutionary   War,  the   original
    thirteen states were impoverished and were confronted
    with the problem of paying the debts created by the
    war.    States without western lands demanded that
    Virginia, and other states claiming such lands to the
    west, should cede the same to the Confederation to be
    sold to pay such debts.         In 1783 the Virginia
    legislature authorized the ceding of the Northwest
    26
    The legislature is "bound by its duty to protect the
    navigable waters of the state for the citizens' benefit" and "to

    Territory to the Confederation, and the actual deed of
    conveyance was executed March 1, 1784.    This cession
    was made upon two conditions: (1) The new states to be
    admitted as members of the Federal Union were to have
    the same rights to sovereignty as the original states;
    and (2) the navigable waters flowing into the
    Mississippi and the St. Lawrence rivers, and the
    carrying places between them, were to be forever free
    public highways.   These conditions were incorporated
    into the Northwest Ordinance of 1787, which set up the
    machinery   for  the   government  of   the  Northwest
    Territory.
    Sec. 1, art. IX of the Wisconsin constitution,
    adopted by the territorial convention on February 17,

    Wisconsin into the Union, incorporated verbatim the
    wording of the Northwest Ordinance with respect to
    navigable waters . . . .

    ¶74    Justice     Currie    then       explained      that       a    number    of
    questions    rise     naturally       from    the    article:      (1)       What    are
    "navigable waters"?          (2) Who owns the "land" under "navigable
    waters"?     (3) What are the public rights in navigable streams
    apart from navigation for commercial purposes?                    (4) What are the
    geographic limits of the public trust in navigable waters?                           Id.
    at 500–08.
    ¶75    The answers to these questions, in Muench and other
    cases, are interrelated, and they help to explain the District's
    concern with the DNR's position.
    1. Questions Raised by the Public Trust Doctrine
    ¶76    The     public    trust     doctrine      is     premised        upon    the
    existence    of   "navigable      waters."          The    test   of       navigability
    discussed in Olson v. Merrill, 
    42 Wis. 203
    , 212 (1877), whether
    a stream has the capacity to float logs to market (at least part
    34
    No.    2008AP1523
    of the year), has long since been replaced by the standard of
    "navigable in fact for any purpose."27     Muench, 261 Wis. at 505–
    06.
    [S]ince 1911 it is no longer necessary in determining
    navigability of streams to establish a past history of
    floating   of  logs,  or   other  use   of  commercial
    transportation, because any stream is "navigable in
    fact" which is capable of floating any boat, skiff, or
    canoe, of the shallowest draft used for recreational
    purposes.
    Id. at 506; see also Bleck, 
    114 Wis. 2d at 459
    ; DeGayner & Co.
    v. DNR, 
    70 Wis. 2d 936
    , 946–47, 
    236 N.W.2d 217
     (1975).
    ¶77    The DNR's position seeks to extend its public trust
    jurisdiction28 beyond navigable waters to non-navigable waters
    and land.      Wetlands are often not "navigable in fact."        Non-
    navigable land is by definition not navigable and may not be
    marshy or "wet."      Eliminating the element of "navigability" from
    the public trust doctrine would remove one of the prerequisites
    for    the    DNR's   constitutional   basis   for   regulating    and
    27
    Justice Currie cites Olson v. Merrill, 
    42 Wis. 203
    , 212
    (1877), as one of the early cases that established the "saw-log"
    test.    Muench v. Pub. Serv. Comm'n, 
    261 Wis. 492
    , 500, 
    53 N.W.2d 514
     (1952). The "saw-log" test first appears in Whisler
    v. Wilkinson, 
    22 Wis. 546
     (*572), 549 (*576) (1868).

    management matters to the DNR."   Wis.'s Envtl. Decade, Inc. v.

    to    non-navigable     land   above    the    OHWM   would    eliminate        the
    rationale   for   the    doctrine.       The   ramifications        for    private
    property owners could be very significant.
    ¶78   The public trust doctrine vests the ownership of land
    under lakes——i.e., lake beds——in the state.               By contrast, the
    public trust doctrine in Wisconsin gives riparian owners along
    navigable streams a qualified title in the stream beds to the
    center of the stream, while the state holds the navigable waters
    in trust for the public.           In reality, the state effectively
    29
    This court has rejected theories that attempt to extend
    the public trust doctrine beyond its historical limitations.
    For instance, in DeGayner & Co. v. DNR, 
    70 Wis. 2d 936
    , 
    236 N.W.2d 217
     (1975), the court reviewed the issue of whether Five
    Mile Creek, a tributary of the Namekagon River in Bayfield
    County, was navigable in fact, thereby requiring a permit to
    construct a dam to create an artificial lake.    
    Id.
     at 938–39.
    While the court determined that the creek was navigable in fact,
    it rejected a theory offered by an amicus that a stream should
    be considered "as a navigable water [irrespective of any other
    finding], because it is a tributary of a natural and valuable
    navigable resource, the Namekagon river."     
    Id. at 948
    .    The
    DeGayner court continued:
    There is evidence to show that the flow of spring
    water from Five Mile Creek is important in maintaining
    the   fish  life   and  the   water   quality  of  the
    Namekagon . . . .   [Nonetheless, the] test, proposed
    by the amicus . . . , has not been recognized by the
    statutes or by the common law; and, as the trial judge
    pointed out, that test, in its simplistic form, can be
    carried to ridiculous extremes, for it would mean that
    all tributaries, since they eventually run into some
    navigable body of water, must be held navigable.
    
    Id.

    actually owning it.

    Keokuk (1876), 
    94 U.S. 324
    , 
    24 L. Ed. 224
    , declared
    that the individual states have the right to determine
    for themselves the ownership of land under navigable
    waters. At an early date in its history the Wisconsin
    court put itself on record as favoring the trust
    doctrine, that the state holds the beds underlying
    navigable waters in trust for all of its citizens,
    subject only to the qualification that a riparian
    owner on the bank of a navigable stream has a
    qualified title in the stream bed to the center
    thereof. See the discussion of this subject in
    McLennan v. Prentice (1893), 
    85 Wis. 427
    , 443-445, 
    55 N.W. 764
    .
    Muench, 261 Wis. at 501–02.
    ¶80   Muench quotes two sentences from Illinois Steel Co. v.
    Bilot:
    The United States never had title, in the
    Northwest Territory out of which this state was
    carved, to the beds of lakes, ponds, and navigable
    rivers, except in trust for public purposes; and its
    trust in that regard was transferred to the state, and
    must there continue forever, so far as necessary to
    the   enjoyment    thereof   by  the   people  of   this
    commonwealth.   Whatever concession the state may make
    without violating the essentials of the trust, it has
    been   held,   can    properly  be   made   to  riparian
    proprietors.
    Id. at 502 (quoting Ill. Steel Co. v. Bilot, 
    109 Wis. 418
    , 426,
    
    84 N.W. 855
     (1901)).
    ¶81   The Bilot case went on to say:
    Under that [concession to riparian proprietors], by
    long-established judicial policy, which has become a
    rule of property, a qualified title to submerged lands
    of rivers navigable in fact has been conceded to the
    37
    No.       2008AP1523
    owners of the shores.    Otherwise the title to lands
    under all public waters is in the state, and it is
    powerless to change it. . . . Hence we must presume
    from the evidence that the title to the land in
    dispute is where the evidence tends to show it is. We
    should say in passing that the term "qualified title"
    as above used refers to that interest in the beds of
    navigable  streams   which   has  passed   to  private
    ownership according to the uniform holdings of this
    court,——a full title, subject to the public rights
    which were incident to the lands forming such beds at
    the time of the creation of the trust above mentioned.
    No private ownership has been conceded which displaces
    or materially affects such public rights. As to them
    the state has not abdicated and cannot abdicate its
    trust.
    Bilot, 109 Wis. at 426 (emphasis added).
    ¶82       The state's ownership of lake beds was confirmed in
    State       v.    McDonald      Lumber    Co.,    
    18 Wis. 2d 173
    ,      176,       
    118 N.W.2d 152
            (1962),    Wisconsin's      Environmental    Decade,       Inc.    v.
    DNR, 
    85 Wis. 2d 518
    , 526, 
    271 N.W.2d 69
     (1978), and State v.
    Trudeau, 
    139 Wis. 2d 91
    , 101–02, 
    408 N.W.2d 337
     (1987).                             The
    rule is different with respect to the beds under streams30 in
    part    because      streams     can     change   course,   streams   can     become
    unnavigable over time, and navigable streams can be very narrow
    and shallow, so that state ownership of stream beds could be
    problematic and impractical.
    ¶83       Writing in Diana Shooting Club, Justice Vinje observed
    that "[i]t would no doubt have been more logical to hold, as
    English          courts   do,     that     private     ownership      ends      where
    30
    "In some of the states embraced within the Northwest
    territory the title to the bed of navigable streams remained in
    the state.    In Wisconsin it is held to be in the riparian
    owners." Diana Shooting Club, 156 Wis. at 268.
    38
    No.     2008AP1523
    navigability begins."         Diana Shooting Club, 156 Wis. at 269.
    But he added that,
    there is nothing inconsistent in the doctrine of
    private ownership of beds of navigable streams subject
    to all the burdens of navigation and the incidents
    thereof.  As long as the state secures to the people
    all the rights they would be entitled to if [the
    state] owned the beds of navigable rivers, it fulfills
    the trust imposed upon it by the organic law which
    declares that all navigable waters shall be forever
    free.
    Id.
    ¶84   Contemplating the question of ownership is important
    because the public trust doctrine implicates state ownership or
    virtual state ownership——by virtue of its trust responsibility——
    of    land   under   navigable   waters.      If     the    public    trust   were
    extended     to cover    wetlands that      are     not    navigable,   it would
    create significant questions about ownership of and trespass on
    private land, and it would be difficult to cabin expansion of
    the state's new constitutionally based jurisdiction over private
    land.31
    ¶85   In   its   discussion   of    public    trust,    the    DNR   points
    specifically to M&I Marshall & Ilsley Bank v. Town of Somers,
    
    141 Wis. 2d 271
    , 288, 
    414 N.W.2d 824
     (1987), where this court
    31
    Virtual state ownership of navigable waters and the land
    beneath navigable waters——under the public trust doctrine——does
    not implicate questions of eminent domain.    The State has no
    need to take what it already "owns."        However, geographic
    expansion of the public trust beyond the boundaries of the OHWM
    of navigable waters would inevitably raise a slew of new
    questions about just compensation.  This has never been a part
    of public trust jurisprudence.
    39
    No.         2008AP1523
    stated that a parcel of private wetland located "partly within
    and partly outside a shoreland area should be treated as if the
    entire wetland was located within a shoreland area."                        To apply
    this reasoning to the scope of the public trust doctrine would
    not represent a logical application of the doctrine.
    ¶86     There is no constitutional foundation for public trust
    jurisdiction over land, including non-navigable wetlands, that
    is not below the OHWM of a navigable lake or stream.                        Applying
    the state's police power to land above or beyond the OHWM of
    navigable waters——to protect the public interest in navigable
    waters——is different          from    asserting    public    trust    jurisdiction
    over non-navigable land and water.
    ¶87     The    public    trust    doctrine    entails    public       rights    in
    navigable    waters,     including      non-commercial       "sailing,       rowing,
    canoeing, bathing, fishing, hunting, skating, and other public
    purposes."         Nekoosa-Edwards     Paper Co.,     201    Wis. at       47.      The
    state's    public     trust    duty    "requires    the     state    not    only     to
    promote navigation but also to protect and preserve its waters
    for fishing, hunting, recreation, and scenic beauty."                            Wis.'s
    Envtl. Decade, 
    85 Wis. 2d at 526
     (emphasis added).                         The court
    cited Muench to support scenic beauty.
    ¶88     Applying the "scenic beauty" referenced in Muench and
    Wisconsin's Environmental Decade to this case takes the concept
    beyond its original purpose to protect and preserve navigable
    "waters."     In Muench, the court noted the passage of Chapter
    523, Laws of 1929, which amended 
    Wis. Stat. § 31.06
    (3) "so as to
    provide that the enjoyment of scenic beauty is a public right to
    40
    No.         2008AP1523
    be   considered    by    the    Public        Service    Commission        in    making
    findings as to whether a permit for a proposed dam shall be
    issued."     Muench, 261       Wis. at    508.32        See   also   DeGayner,         
    70 Wis. 2d at 949
    .
    ¶89    Considering        scenic     beauty        in    relation          to     the
    construction   of a     dam    in navigable        waters     is   different          from
    claiming public rights under the public trust doctrine to the
    scenic    beauty   of   non-navigable         shoreland.      Yet,       the    DNR    has
    taken the position that the public trust doctrine protects a
    public right to "scenic beauty (which on its face extends to the
    shore above the OHWM)."
    ¶90    Article IX, Section 1, does not vest the state with
    constitutional     trust      powers    to     "protect"      scenic       beauty       by
    regulating non-navigable land bordering lakes and rivers.                              As
    will be noted, the state may have statutory authority to weigh
    in on scenic beauty beyond its public trust jurisdiction, but
    giving the state constitutional trust power to regulate "scenic
    beauty" would arguably give the state authority to regulate any
    private land that could be seen from navigable waters.

    In Just v. Marinette County, 
    56 Wis. 2d 7
    , 
    201 N.W.2d 761
    (1972), the state correctly argued in its brief to this court
    that the public trust doctrine requires the legislature to
    preserve the trust in navigable waters: "The carrying out of
    that duty requires not only a promotion of navigation . . . but
    the protection and preservation of the incidents to navigation
    such as hunting, fishing, recreation, and scenic beauty, as they
    are defined in Muench v. Public Service Comm[ission] (1952), 
    261 Wis. 492
    ,

    ¶91   Public trust jurisdiction has always been confined to
    a limited geographic area.             In Diana Shooting Club, the court
    said:
    Hunting on navigable waters is lawful when it is
    confined strictly to such waters while they are in a
    navigable stage,    and   between the    boundaries   of
    ordinary high-water marks.     When so confined it is
    immaterial what the character of the stream or water
    is. It may be deep or shallow, clear or covered with
    aquatic vegetation.    By ordinary high-water mark is
    meant the point on the bank or shore up to which the
    presence and action of the water is so continuous as
    to   leave  a   distinct   mark   either   by   erosion,
    destruction of terrestrial vegetation, or other easily
    recognized characteristic.   Lawrence v. Am. W[riting]

    144 Wis. 556
    , 562, 
    128 N.W. 440
     [(1910)].
    And where the bank or shore at any particular place is
    of such a character that it is impossible or difficult
    to ascertain where the point of ordinary high-water
    mark is, recourse may be had to other places on the
    bank or shore of the same stream or lake to determine
    whether a given stage of water is above or below
    ordinary high-water mark.

    ¶92   The   Diana   Shooting    Club   holding    was    reaffirmed     in
    Trudeau, 
    139 Wis. 2d at 104
    , where the court stated that "Lake
    Superior is navigable and if the non-navigable site is a part of
    the lake, then the land below the OHWM is held in trust for the
    public."      (Emphasis added.).        See also McDonald Lumber Co., 
    18 Wis. 2d at

         (Ct.    App.   1982)    ("[T]he    OHWM   marks    the   boundary
    between lake bed titled in the state, which is subject to state
    regulation     in     the   public    interest,   and    property     titled    in
    private owners.").
    42
    No.         2008AP1523
    ¶93    The limitation thus stated in the cases is clearly
    inconsistent       with     the     interpretation             of   the     public           trust
    doctrine espoused by the DNR.
    ¶94    In sum, we believe the District has raised legitimate
    concerns about the DNR's reliance upon the public trust doctrine
    as authority for some of its regulation in this case.
    2. Police Power as a Basis for Protecting Water Resources
    ¶95    This review of the constitutionally based public trust
    doctrine    does     not    disarm       the       DNR    in   protecting        Wisconsin's
    valuable    water    resources.           For       instance,       the   DNR     has        broad
    statutory    authority       grounded         in    the    state's    police          power     to
    protect    wetlands        and    other    water         resources.        See        Just,     
    56 Wis. 2d at
    10–11.          This police power is sometimes buttressed by
    requirements imposed by federal law.                       Moreover, the agency has
    explicit statutory authority in this case to consider the impact
    of the water levels of Lake Koshkonong on public and private
    wetlands adjacent to the lake, 
    Wis. Stat. § 31.02
    (1), because it
    has police power authority to "protect . . . property."
    ¶96    The     Just    case    is    a     textbook       example      of    using        the
    state's     police     power       to     support         legislation           "to     protect
    navigable     waters       and     the    public          rights    therein           from     the
    degradation    and deterioration which                    results    from       uncontrolled
    use and development of shorelands."                       Id. at 10.        The Wisconsin
    Legislature approved the Water Quality Act of 1965 by Chapter
    614, Laws of 1965.           The Act authorized the passage of shoreland
    zoning ordinances by counties, subject to certain requirements.
    Marinette County passed such an ordinance.                          It later prosecuted
    43
    No.     2008AP1523
    Ronald Just for filling in wetlands on his shoreland property
    without a required permit.                Id. at 14.
    ¶97   When the case reached the supreme court, the court
    explained      that     the   real     issue      was   whether   "the       conservancy
    district      provisions      and    the     wetlands-filling         restrictions     are
    unconstitutional because they amount to a constructive taking of
    the Justs' land without compensation."                  Id.
    ¶98   Marinette       County       and    the   state     argued      that     the
    contested      provisions       constituted        "a   proper    exercise       of    the
    police power of the state and do not so severely limit the use
    or depreciate the value of the land as to constitute a taking
    without compensation."              Id.      The state's principal argument in
    its brief had been that "[t]he Marinette County Shoreland Zoning
    Ordinance      Is   A   Valid       Police    Power     Regulation."          The     state
    explained that the purpose of the ordinance was not intended to
    "preserve wetlands in their natural state.                     The basic purpose of
    the ordinance is the protection of navigable waters, and the
    public rights therein, from the degradation and deterioration
    which    results      from    the    uncontrolled        use    and    development      of
    shorelands."        The state said:
    It has long been the law in Wisconsin that laws
    and regulations to prevent pollution and protect the
    waters of the state from degradation are valid police
    power enactments. . . .   The basis for such police
    power regulation is the legislature's duty to promote
    the general health, safety and welfare and to protect
    and preserve the public trust in navigable waters of
    the State of Wisconsin.
    . . . .
    44
    No.      2008AP1523
    The ordinance should . . . be upheld as a valid police
    power regulation.
    The court then responded in the Just opinion as follows:
    The protection of public rights may be accomplished by
    the exercise of the police power unless the damage to
    the property owner is too great and amounts to a
    confiscation. The securing or taking of a benefit not
    presently enjoyed by the public for its use is
    obtained by the government through its power of
    eminent domain.   The distinction between the exercise
    of the police power and condemnation has been said to
    be a matter of degree of damage to the property owner.
    In the valid exercise of the police power reasonably
    restricting the use of property, the damage suffered
    by the owner is said to be incidental. However, where
    the restriction is so great the landowner ought not to
    bear   such  a burden for      the public good,    the
    restriction has been held to be a constructive taking
    even though the actual use or forbidden use has not
    been transferred to the government so as to be a
    taking in the traditional sense.
    Id. at 15.
    ¶99     The court's emphasis on the state's police power is
    evident in the following passages:
    This case causes us to re-examine the concepts of
    public benefit in contrast to public harm and the
    scope of an owner's right to use of his property. In
    the instant case we have a restriction on the use of a
    citizen['s] property, not to secure a benefit for the
    public, but to prevent a harm from the change in the
    natural character of the citizens' property. . . .
    What makes this case different from most condemnation
    or police power zoning cases is the interrelationship
    of   the   wetlands,   the   swamps   and  the   natural
    environment of shorelands to the purity of the water
    and to such natural resources as navigation, fishing,
    and scenic beauty.      Swamps and wetlands were once
    considered     wasteland,     undesirable,   and     not
    picturesque.      But   as   the   people  became   more
    sophisticated, an appreciation was acquired that
    swamps and wetlands serve a vital role in nature, are
    part of the balance of nature and are essential to the
    45
    No.      2008AP1523
    purity of the water in our lakes and streams. Swamps
    and wetlands are a necessary part of the ecological
    creation and now, even to the uninitiated, possess
    their own beauty in nature.
    The exercise of the police power in zoning must be
    reasonable and we think it is not an unreasonable
    exercise of that power to prevent harm to public
    rights [in navigable waters] by limiting the use of
    private property to its natural uses.
    . . . .
    Wisconsin has long held that laws and regulations
    to prevent pollution and to protect the waters of this
    state    from   degradation  are   valid   police-power
    enactments.
    Id. at 16-18.33
    ¶100 If       there     is       any    question     that    the    court    was        not
    relying on the public trust doctrine to sustain the shoreland
    zoning        ordinance       and    its       authorizing    legislation,        the      court
    noted        that    the     Marinette         County   ordinance     applied       to    "lands
    within        1,000     feet        of    the     normal     high-water       elevation         of
    navigable           lakes,    ponds,       or     flowages     and    300     feet       from     a
    navigable river or stream."                      Id. at 10.         These dimensions far
    exceed the geographic limitations of public trust jurisdiction.
    It should be obvious that the state does not have constitutional
    public trust jurisdiction to regulate land a distance of more
    than three football fields away from a navigable lake or pond.

    reasonable    doubt.          Nonetheless,          as     Just     makes       clear,    the
    distinction       between    the        DNR's    constitutionally           based     public
    trust    authority     and    the       DNR's     police        power-based        statutory
    authority is that the latter is subject to constitutional and
    statutory protections afforded to property, may be modified from
    time to time by the legislature, and requires some balancing of
    competing interests in enforcement.
    ¶102 Wisconsin        Stat.       § 31.02(1)       also     makes    a    distinction
    between the DNR's public trust authority and its police power
    authority.        Only part        of    
    Wis. Stat. § 31.02
    (1)       embodies      the
    public trust doctrine.         See Wis. Power & Light Co. v. Pub. Serv.
    Comm'n, 
    5 Wis. 2d 167
    , 174, 
    92 N.W.2d 241
     (1958) (stating that
    language                 in                      § 31.02                        "promot[ing]
    safety . . . and . . . protect[ing]                       property"             "involve[s]
    subjects covered by the police power of the state").
    ¶103 If the statute read only that the department "in the
    interest of public rights in navigable waters," may regulate and
    control the level and flow of water in all navigable waters, the
    statute would be seen as a direct enforcement mechanism for the
    public trust in navigable waters.                    But the statute does more.
    It   contains      a   disjunctive          element        giving     the        department
    authority    to    regulate    and       control     the    flow     of    water     in   all
    navigable waters "to promote safety and protect life, health and
    property."     
    Wis. Stat. § 31.02
    (1).               Because the quoted language
    47
    No.      2008AP1523
    follows the key word "or," the department is given distinct and
    different authority to consider interests affected by the level
    of the "navigable waters."
    3. The History of 
    Wis. Stat. § 31.02
    (1) and Application
    ¶104 Wisconsin       Stat.      § 31.02(1)         originated       in    Section    3,
    Chapter 380, Laws of 1915.                  The "or" between the words "the
    interest of public rights in navigable waters" and the words "to
    promote    safety   and    protect          life,      health     and    property"       was
    present in the beginning in relation to the power to control
    water levels.       See Wis.         Stat.       ch.    69m.,   § 1596——2.1.          (1915)
    (created by Section 3 of Chapter 380, Laws of 1915).
    ¶105 By contrast, Wis. Stat. ch. 69m., § 1596——7.3. (1915),
    created by the same section of ch. 380, directs the Railroad
    Commission to consider whether "the construction, operation or
    maintenance of the proposed dam will not materially obstruct
    existing navigation or violate other public rights and will not
    endanger life, health or property."                    (Emphasis added.)
    ¶106 Both provisions distinguish "public rights" from other
    interests, and those other interests need not be in or part of
    navigable    waters.      The     section        relating       to    the     water    level
    regulations    appears     to        give     the       Railroad      Commission       some
    discretion    about    what     it     will       consider;       the    other    section
    requires    consideration       of    multiple          factors      before    permitting
    construction of a dam.
    ¶107 Clearly, both sections empower the Railroad Commission
    to consider water level effects on property.                            Flooding was an
    obvious concern.       The early statutes contain frequent references
    48
    No.      2008AP1523
    to flooding caused by dams.                           We see no reason, however, why
    "property"      would       not         include              property       rights        generally,
    particularly riparian rights under common law.
    ¶108 The "bundle of rights conferred upon a property owner
    by virtue of his contiguity to a body of water, whether a lake
    or   stream,    are       referred          to       as     riparian      rights."         Mayer    v.
    Grueber, 
    29 Wis. 2d 168
    , 174, 
    138 N.W.2d 197
     (1965).                                         "It is
    clear in Wisconsin that the mere fact that one owns property
    abutting a natural body of water presumptively confers certain
    rights."       Id.; see also Stoesser v. Shore Drive P'ship, 
    172 Wis. 2d 660
    , 667, 
    494 N.W.2d 204
     (1993).                                   We see no evidence
    that the legislature in 1915 intended to exclude riparian rights
    from the consideration of property in 
    Wis. Stat. § 31.02
    (1).
    ¶109 Property         abutting             a    natural       body    of    water     includes
    wetlands,      which       make        up     12.4          miles    of     Lake        Koshkonong's
    shoreline.        The      District          acknowledges            that    "privately          owned
    wetlands    are      entitled      to        consideration             as   'property'        to   be
    protected in establishing a water level order."                                  There can be no
    dispute that the DNR can consider water level impact on all
    adjacent property under 
    Wis. Stat. § 31.02
    (1).
    ¶110 No     property         owner's             riparian        rights      are    absolute.
    They are balanced against the rights of other riparians and the
    public,    particularly           if    they           impinge      upon    public        rights   in
    navigable    waters.         But        the          rights    of    all    riparians       must   be
    considered      in    a    water        level              determination.           The    DNR     may
    emphasize      some       rights            over          others     in     its      water       level
    determinations, and its exercise of discretion will normally be
    49
    No.     2008AP1523
    upheld so long as it considers all property rights and so long
    as it does not accord some non-navigable land or water above the
    OHWM    a   constitutional        preference     as    trust    land       over    other
    property.
    C. Application of Water Quality Standards
    ¶111 We     next    turn    to    the   District's           contention         that
    applying     wetland      water    quality     standards       in     a    
    Wis. Stat. § 31.02
    (1) water level determination, specifically water quality
    standards in Wis. Admin. Code § NR 103,34 is expressly prohibited
    by 
    Wis. Stat. § 281.92
    .
    ¶112 The District asserts          that    the    legislature         delegated
    rule-making authority to the DNR in Chapter 614, Laws of 1965.
    Chapter 614 extensively revised then-Wis. Stat. ch. 144 of the
    statutes, giving what is now the DNR a directive to "adopt rules
    setting     standards     of   water    quality   to    be     applicable         to    the
    waters of the state, recognizing that different standards may be
    required for different waters or portions thereof."35                       § 37, ch.
    614, Laws of 1965.
    34
    Chapter NR 103 was promulgated pursuant to 
    Wis. Stat. § 281.15
    (2)(b), which authorizes the DNR to adopt rules for
    wetland water quality standards.
    35
    Wisconsin Stat. § 144.025(2)(b) (1965), which is now 
    Wis. Stat. § 281.15
    (1), read in full:
    The   department   shall   adopt   rules  setting
    standards of water quality to be applicable to the
    waters of the state, recognizing that different
    standards may be required for different waters or
    portions thereof.   Such standards of quality shall be
    such as to protect the public interest, which include
    the protection of the public health and welfare and
    the present and prospective future use of such waters
    50
    No.        2008AP1523
    ¶113 Chapter 614 defined "waters of the state":
    "Waters of the state" includes those portions of
    Lake Michigan and Lake Superior within the boundaries
    of Wisconsin, and all lakes, bays, rivers, streams,
    springs, ponds, wells, impounding reservoirs, marshes,
    watercourses, drainage systems and other surface or
    ground   water, natural    or  artificial,   public or
    private, within the state or its jurisdiction.
    
    Wis. Stat. § 144.01
    (1) (1965).
    ¶114 The District asserts that:
    DNR erred as a matter of law in applying ch. NR 103.
    Those rules, which define wetland functions and values
    and are intended to be determinative of regulatory
    decisions, were promulgated under the authority of ch.
    281.   But DNR's authority to apply rules promulgated
    under sec. 281.15 has always been limited by sec.
    281.92, which provides: "Nothing in this chapter [ch.
    281] affects ss. 196.01 to 196.79 or ch. 31."
    Therefore,     the   District   concludes,       consideration    of    "public
    rights    in   navigable   waters"   in   
    Wis. Stat. § 31.02
    (1)     cannot
    include the application of water quality standards in Wis. Stat.
    ch. 281 and its underlying administrative code.              In effect, the
    District contends that nothing in Wis. Stat. ch. 281 affects
    Wis. Stat. ch. 31.36
    for public and private water supplies, propagation of
    fish and aquatic life and wildlife, domestic and
    recreational purposes and agricultural, commercial,
    industrial and other legitimate uses.   In all cases
    where the potential uses of water are in conflict,
    water quality standards shall be interpreted to
    protect the general public interest.
    36
    A March 27, 2006, memorandum from Patricia Ann Trochlell
    of the DNR——labeled Exhibit 850 at the contested case hearing——
    appears to confirm the District's contention, as Trochlell
    wrote:
    51
    No.         2008AP1523
    ¶115 Once         again,   the    text      of        
    Wis. Stat. § 31.02
    (1)
    authorizes the DNR to "regulate and control the level and flow
    of water in all navigable waters" in the interest of "public
    rights in navigable            waters     or   to     promote        safety      and    protect
    life,        health    and   property."        Some      of    the    "property"          to   be
    "protected" is wetlands, both public and private.                                 How should
    the DNR square this with 
    Wis. Stat. § 281.92
    ?
    ¶116 The District's reading of these two statutes——that the
    DNR cannot apply wetland water quality standards in § NR 103
    when     making       a   § 31.02(1)     water      level      determination——is               not
    reasonable.           The DNR should not be forced to ignore relevant
    statutes        and    its   own   administrative         rules       on    water       quality
    standards in making a water level determination.                            It should not
    be     forced     to      disregard    its     recognized        statewide         statutory
    mission as well as its own property.37
    Questions have arisen regarding the department's
    authority to consider water quality standards for
    activities regulated under ch. 31.          Ch. 281.92
    provides: "Nothing in this subchapter affects ss.
    196.01 to 196.79 or ch. 31.["]     This means that the
    department cannot apply water quality standards such
    as NR 102 and NR 103 to dams regulated under ch. 31.
    (Emphasis added.)    However, Trochlell goes on to state that
    DNR's responsibility under 
    Wis. Stat. § 31.02
    (1), "in the
    interest of public rights in navigable waters" and to "promote
    safety and protect life, health and property" requires DNR to
    "consider [effects] to wetlands under ch. 31 when evaluating
    water level impacts to wetlands." (Emphasis added.)
    37
    See 
    Wis. Stat. § 281.11
     ("The [DNR] shall serve as the
    central unit of state government to protect, maintain and
    improve the quality and management of the waters of the state,
    ground and surface, public and private.").

    ¶117 The    history          of    the      two    statutes       at     issue      is
    enlightening.        As     previously       noted,       
    Wis. Stat. § 31.02
         was
    originally enacted in 1915 as Section 1596——2.1. of ch. 69m.
    § 3, ch. 380, Laws of 1915 (the Water Powers Act).                             The statute
    in 1915 read: "The commission, in the interest of public rights
    in   navigable     waters      or    to    promote       safety   and    protect        life,
    health and property is empowered to regulate and control the
    level and flow of water in all navigable waters."                              Wis. Stat.
    ch. 69m, § 1596——2.1. (1915).                   This section was renumbered in
    1917 as 
    Wis. Stat. § 31.02
    , as part of the newly created Wis.
    Stat. ch. 31.       § 3, ch. 474, Laws of 1917.                   The new § 31.02 was
    entitled    "Powers       of    the       railroad       commission"          because     the
    Railroad Commission was the state agency originally responsible
    for making water level determinations.
    ¶118 Wisconsin Stat. § 281.92 was first enacted in 1919,
    four    years     after     the       predecessor         statute     to      
    Wis. Stat. § 31.02
    (1).       Section 1407m——1.(12) stated: "Nothing in this act
    shall be construed to alter, amend, repeal, impair, or affect
    any of the provisions of sections 1797m——1 to 1797m——109 or of
    chapter 31 of the Wisconsin statutes."                      § 2, ch. 447, Laws of
    1919 (emphasis added).              The state board of health originally had
    the responsibility for enforcing the predecessor to Wis. Stat.
    ch. 281.   See generally ch. 447, Laws of 1919.
    ¶119 Four years later, the latter statute was renumbered as
    
    Wis. Stat. § 144.12
           and       amended    to    read,     "Nothing      in     this
    chapter shall be construed to affect the provisions of sections
    1797m——1 to 1797m——109 or of chapter 31 of the statutes."                               § 27,
    53
    No.     2008AP1523
    ch. 448, Laws of 1923.             This section was renumbered as 
    Wis. Stat. § 144.27
       in    1979,    § 624,   ch.   221,   Laws    of    1979,   and
    finally renumbered as the current 
    Wis. Stat. § 281.92
     in 1995.
    1995 Wis. Act. 227, § 435.
    ¶120 The court of appeals looked at this history and made
    the following observations:
    This statutory history shows that 
    Wis. Stat. § 281.92
     was originally adopted to demarcate the
    regulatory spheres of influence of the state Board of
    Health and the Railroad Commission; the Board of
    Health's   water  purification   and  water   pollution
    prevention responsibilities were not to affect the
    authority of the Railroad Commission in dam regulation
    under Wis. Stat. ch. 31, and the Railroad Commission's
    responsibilities were not to affect the authority of
    the Board of Health in its sphere of regulation.

    336 Wis. 2d 677
    , ¶60.                 Now that both
    Wis. Stat. ch. 281 and ch. 31 responsibilities fall to the DNR,
    the court of appeals said, the District's reading of these two
    statutes is illogical.       
    Id.
    ¶121 In our view, the effect of 
    Wis. Stat. § 281.92
     upon
    
    Wis. Stat. § 31.02
    (1) cannot be so easily dismissed.                   Wisconsin
    Stat.    § 281.92   has   remained    essentially    intact      for    nearly   a
    century, including almost 50 years in which the DNR has had the
    dual responsibility of enforcing Wis. Stat. chs. 31 and 281.
    The DNR's jurisdiction in Wis. Stat. ch. 281 is broader and
    different from its jurisdiction in Wis. Stat. ch. 31.                     If the
    purpose served by 
    Wis. Stat. § 281.92
     had ceased to exist, the
    statute would probably have been amended or eliminated rather
    than simply renumbered.

    ¶122 Ultimately,               we     must     interpret      both        
    Wis. Stat. §§ 31.02
    (1) and 281.92 in a way that harmonizes the purposes of
    the two statutes.                "Apparently conflicting provisions of law
    should be construed so as to harmonize them and thus give effect
    to the leading idea behind the law."                      Beard v. Lee Enters.,

    interest of "public rights in navigable waters" is too absolute.
    As     the     court        of        appeals       stated,    the    more        reasonable
    interpretation is that "nothing in the DNR's water protection
    responsibilities under ch. 281 and the associated administrative
    rules expands or restricts its responsibilities to set water
    levels       under

    , ¶57.                    That interpretation harmonizes the
    statutes and "give[s] effect to" the idea behind both laws: that
    the DNR should not be straitjacketed when managing the water
    resources of this state.                   Beard, 
    225 Wis. 2d at 15
    .
    ¶123 The DNR may consider the water quality standards in
    Wis. Admin. Code § NR 103, promulgated under Wis. Stat. ch. 281,
    when making a 
    Wis. Stat. § 31.02
    (1) water level determination.
    Full     consideration           of    these     standards     is    different          from    a
    requirement          that     the      DNR    always     apply      them    in     making       a
    § 31.02(1) determination.
    ¶124 As we understand it, the DNR did not apply the § NR
    103 wetland water quality standards in this case.                                Rather, the
    analysis in the ALJ's Decision stated that the DNR evaluated the
    55
    No.        2008AP1523
    proposed     water      level    increase      in    the     District’s            Petition
    "against the appropriate regulatory standards, including chapter
    NR 103, Wis. Admin. Code."
    ¶125 Therefore,      we     conclude     that      the    DNR     may       consider
    wetland water quality standards in Wis. Admin. Code § NR 103
    when    making     a    water    level    determination          under        
    Wis. Stat. § 31.02
    (1).       Wisconsin Stat. § 281.92 does not preclude the DNR
    from applying the wetland water quality standards in § NR 103 or
    other parts of ch. 281, when appropriate, after weighing factors
    under § 31.02(1).
    D. Consideration of Economic Impacts
    ¶126 We turn now to the District's final contention that it
    was wrong as a matter of law for the DNR to exclude most of the
    evidence of economic impacts at the contested case hearing.                                The
    District argues that the requirement in 
    Wis. Stat. § 31.02
    (1) to
    "protect . . . property" should be broadly interpreted so as to
    consider    the    effect   of     proposed    water       levels      on     residential
    property values, business income, and local tax revenue.                                   The
    DNR, on the other hand, asserts that it properly interpreted
    "protect . . . property"           to   include     consideration            of   only     the
    direct "hydrologic impacts" to real property like flooding and
    the impacts on          the utility      and   enjoyment        of   riparian        access
    rights.
    ¶127 Statutory interpretation starts with the text of the
    statute.     State ex rel. Kalal v. Circuit Court for Dane Cnty.,

    Id.
            However, if a statute is ambiguous——that is,
    "capable of being understood by reasonably well-informed persons
    in    two   or    more       senses"——then           a    reviewing    court       may    turn   to
    scope, history, context, and purpose of the statute.

    ¶128 Wis. Stat. ch. 31 does not define "property."38                                 If the
    legislature       does       not    provide a            definition,    we    may    resort to
    dictionaries.           DOR v. River City Refuse Removal, Inc.,

    .                              However, dictionary
    definitions are not especially helpful to us in this case.                                    See,
    e.g., The American Heritage Dictionary of the English Language
    1452    (3d      ed.    1992)       (defining        "property"       as     "1.a.       Something
    owned;      a    possession.          b.    A    piece         of    real    estate . . . c.
    Something tangible or intangible to which its owner has legal
    title"); Black's Law Dictionary 1232 (7th ed. 1999) (defining
    "property"        as     "The       right       to       possess,     use,     and       enjoy    a
    determinate thing").
    ¶129 Regardless of how property is defined, certain rights
    are traditionally associated with property ownership.                                    These are
    known as the "bundle of rights" and commonly include the right
    "to    possess,        use    and    dispose"            of   the   property,      among     other
    38
    As one legal scholar put it, "What is property?    Nearly
    every first-year property course [in law school] begins and ends
    with   this   query.     The   instructor   never  answers   the
    question. . . .    The question is unanswerable because the
    meaning of the chameleon-like word property constantly changes
    in time and space."        John Edward Cribbet, Concepts in

    ¶130 In this case, we must determine whether the DNR must
    consider     the     effects        of    a     water       level     determination       on   the
    economic     incidents         of    "property."              The     meaning    of    the     word
    "property," as used in 
    Wis. Stat. § 31.02
    (1), is not clear on
    its face in the context presented.                          Thus, the word is ambiguous,
    as the court of appeals initially concluded in its certification
    to this court.
    ¶131 What      does     the       word       "protect"        mean?          Again,    no
    definition of the term exists in Wis. Stat. ch. 31.                                  Definitions
    in   a    standard      dictionary         are    only        marginally       helpful.        The
    American Heritage Dictionary of the English Language 1456 (3d
    ed. 1992) (defining "protect" as "1. To keep from being damaged,
    attacked, stolen, or injured; guard.").
    ¶132 Given       the            lack      of         a       plain      meaning         of
    "protect . . . property," we must look further to interpret this
    58
    No.         2008AP1523
    phrase.       We find that history, purpose, precedent, and the DNR's
    past    practice      support    a     broad      interpretation            of     the      phrase
    "protect . . . property"             so    that       the   DNR       is   not     limited      to
    consideration of hydrologic damage to real property and riparian
    rights when making a water level determination under 
    Wis. Stat. § 31.02
    (1).
    ¶133 The       construction        and     operation       of       dams,      the    water
    levels    upstream      caused       by    dam    placement,          and    a     network      of
    navigable waters have played an important role in Wisconsin's
    economic development since early statehood.                            See, e.g., Joseph
    A.     Ranney,    Trusting      Nothing          to    Providence:           A     History      of
    Wisconsin's Legal System 137 (1999) (discussing the use of dams
    for lumber mills and transportation of goods on navigable waters
    in nineteenth-century Wisconsin).                      The territorial legislature
    recognized the role that dams and streams played in economic
    development with its passage of the Milldam Act.                                  DNR Waterway
    and    Wetland    Handbook,      ch.      140    Dams,      at    2    (stating         that    the
    purpose behind legislative regulation of dams was to "encourage
    economic development").
    ¶134 This      court   also        recognized        the   economic            impacts    of
    dams    and     the   resulting      sustained         water      levels         on    impounded
    bodies of water.         In Fisher v. Horicon Iron & Manufacturing Co.,
    this court, in considering the constitutionality of the Milldam
    Act,    noted    that    "enterprising           towns      and   flourishing           villages
    have grown up" around dams and depend upon the dams for their
    "wealth and prosperity."             Fisher, 
    10 Wis. 293
     (*351), 297 (*354)
    (1860).       In Smith v. Youmans, this court similarly recognized an
    59
    No.         2008AP1523
    interest      that     residential          riparian    owners       acquired           in    higher
    lake    levels     behind       a    dam    maintained        over   a       40-year         period.

    levels       led   property         owners     to    build      summer        homes,          summer
    resorts, and make other "sundry valuable improvements" on lake
    lots.

     (statement of facts).                    While these acts and
    cases predate 
    Wis. Stat. § 31.02
    , the history is instructive as
    to     the     role      dams       and     water    levels      played            in    economic
    development.
    ¶135 In       1909    the        legislature       created       a    joint          Special
    Legislative Committee on Water Powers, Forestry, and Drainage.
    A.J.R. 8, Laws of 1909.                    Two members of this joint committee,
    state    Senators        Paul   O.        Husting    and    Henry    Krumrey,            issued    a
    report       to    the       governor        and     legislature         detailing             their
    observations of impounded lakes while touring the state with the
    joint committee:
    Summer resorts have sprung up along the lake shores
    and summer homes have been built by people from
    various parts of the state and of the United States.
    Piers have been built into the lakes and other
    improvements made by the riparian.    By reason thereof
    the shores are beginning to become very valuable and
    property rights are becoming important.

    was even more expansive in its discussion of water power, the
    resulting reservoirs of water and their importance to industry,
    residential riparians, and commercial recreation interests.                                      See

    very favorable conditions for summer cottages on lake banks and
    launches for tourists and hunters.                   Id. at 27.
    ¶136 The      special       legislative          committee's          full     report
    resulted in the Water Powers Acts of 1911, 1913, and 1915.                                 DNR
    Waterway and Wetland Handbook, at 4.                    The 1915 Water Powers Act
    survived,    while    this    court         found    the    former    two    acts     to    be
    unconstitutional.39         The 1915 act included the requirement that
    the then-Railroad Commission protect property when setting water
    levels.     Wis. Stat. ch. 69m., § 1596——2. (1915).                          In 1917 the
    legislature renumbered the Water Powers Law as Wis. Stat. ch.
    31, with     its requirement           to    protect       property    as    it    survives
    today.     § 3, ch. 474, Laws of 1917.                In light of the legislative
    reports    giving    rise    to   the        Water    Powers    Act    containing          the
    "protect . . .       property" language of 
    Wis. Stat. § 31.02
    (1), one
    can   reasonably     infer      that    riparian        residential         property       and
    lake-based businesses were prime considerations for protecting
    property.
    39
    Chapter 652, Laws of 1911 (the 1911 Water Powers Act) was
    found unconstitutional as a taking of private property without
    compensation.   State ex rel. Wausau St. R.R. Co. v. Bancroft,
    
    148 Wis. 124
    , 
    134 N.W. 330

    (ch. 755, Laws of 1913) was found unconstitutional because it
    did not provide adequate due process.     State ex rel. Owen v.

    ¶137 One         of   the      first     cases      to     interpret         the     new
    requirement       to    protect      property      was    Town     of       Bear   Lake     v.
    Wisconsin-Minnesota Light & Power Co., 16 W.R.C.R. 710 (1915).
    In that case, riparian property owners brought a complaint to
    the Railroad Commission over a plan for a new dam that the
    owners claimed would cause flooding, destroying town highways
    and "rendering valu[e]less much taxable property therein."                                 Id.
    at   710.        The   Railroad      Commission      held      that     property      to    be
    protected from overflow was not limited to land downstream from
    a dam, but applied upstream as well.                     Id. at 717.          Furthermore,
    the respondent power company urged the Railroad Commission to
    accept an expansive view of property in the Water Powers Act;
    namely, the property interests in a water level determination
    are "of sufficient magnitude and importance to the community or
    the state as to make those property interests a matter of public
    concern."        Id. at 719.         Notably, while the decision discussed
    the location of property to be protected and the importance of
    property to the community, the decision did not explicitly limit
    the protection of property to only direct physical impacts.
    ¶138 Another early Railroad Commission case discussing the
    protection       of    property       in     the   context       of     a     water      level
    determination is informative.                  In In re Determining the High
    Water Mark to be Established on the Rest Lake Reservoir Operated
    by the Chippewa & Flambeau Improvement Co., riparian residents
    opposed the raising of water levels on the Rest Lake reservoir
    because     it   would      result    in   "injury       to    their    property."          16
    W.R.C.R. 727, 731 (1915).                  The Railroad Commission recognized
    62
    No.         2008AP1523
    that the waters of the affected area were "among the most famous
    summer resort and fishing waters in the state."                         Id. at 733.
    Residents and resort owners invested "large sums of money" in
    improvements     on   the    waters.       Id.   at    733–34.        The     Railroad
    Commission held:
    We are of the opinion that the Commission is required
    to take into consideration the effect of [water]
    levels fixed by it upon property which may be affected
    by those levels and that where the property to be so
    affected includes the most valuable property in the
    community, is large in acreage, and not shown to be
    subject to overflow, the protection of such property
    is a matter of more than private interest and becomes
    a matter affecting the public welfare.
    Id. at 736.40      Thus, the Railroad Commission in Rest Lake made a
    direct    link   between      protecting      property     in     a     water       level
    determination      and    economic      damage   to    valuable       land.         While
    initially    the      potential      damage      was     physical        in     nature
    (overflowing     of      land),   the    Commission      was     mindful       of    the
    40

    Chippewa & Flambeau Improvement Co. v. Railroad Commission of

    The DNR correctly notes that this court's opinion in
    Chippewa & Flambeau used the words "imperil[]," "injury," and
    "damage" in relation to property.     
    Id.
       The DNR argues that
    these words "connote direct harm to property, not economic harm
    to property values or taxes or business."        We decline the
    invitation to take such a narrow view of these words. While one
    can certainly suffer physical injury, one can also undergo
    economic or financial injury as well, particularly as a result
    physical damage.   See, e.g., U.S. Small Bus. Admin., Economic

    improvements to the land that increased its value and that the
    value would no doubt be affected by the level of the water.41
    ¶139      It is unreasonable to conclude, given the preceding
    history,       context,     and    interpretations      of         the     phrase
    "protect . . . property,"         that    economic   impacts        cannot      be
    considered when making a water level determination under 
    Wis. Stat. § 31.02
    (1).         The DNR, the agency currently charged with
    making     a   water   level   determination    under   § 31.02(1),           must
    protect the same property interests as in 1915 and before——that
    is, not only land itself, but improvements to the land, the

    The DNR and court of appeals look to this court's
    decision in City of New Lisbon v. Harebo, 
    224 Wis. 66
    , 
    271 N.W. 659
     (1937) for support that "protect . . . property" applies
    only to the protection of property from events like flooding.
    Rock-Koshkonong Lake Dist., 
    336 Wis. 2d 677
    , ¶45.   We disagree.
    Harebo was about whether a permit for dam construction under
    
    Wis. Stat. § 31.06
    (3) (1935) was required before condemnation
    proceedings for flowage rights.   Specifically, was condemnation
    of all the flowage rights necessary before the grant of a permit
    so as not to "endanger property"? Harebo, 224 Wis. at 70.
    The Harebo court asked what is meant by property, and
    looked to 
    Wis. Stat. § 31.02
    , which has "precisely the same
    formula" for protecting property as 
    Wis. Stat. § 31.06
    (3)
    (1935). Id. at 72. The court concluded, "It is not proper to
    isolate the word 'property' and assert that injury to property
    means normal flowage by the ordinary operation of the dam, since
    this is the inevitable consequence of building and maintaining a
    dam." Id. at 73.
    The Harebo holding was limited to whether the Public
    Service Commission (at the time, the agency tasked with
    regulating flowage and water level) was required to protect
    property from being flooded by normal dam operation in the
    context of dam permit approval.   While this holding obviously
    implicates physical damage to property, it does not limit the
    protection of property solely to physical impacts such as
    flooding.

    diminished in importance, but now they must be balanced against
    impacts on wildlife, water quality, wetlands, recreation, and
    other more modern considerations.

    guidelines in place for economic considerations when regulating
    water levels        under

    ¶141 Equally significant, the DNR's model shoreland zoning
    ordinance (which was adopted by Marinette County in 1967 and was
    at issue in the Just case) stated in the beginning and states
    now:

     (emphasis added).              Reference to the tax base is generally
    included in county shoreland zoning ordinances.                         See, e.g., Dane
    Cnty., Wis., Code of Ordinances § 11.016(1) (2013); Marinette

    Ordinances, Rock Cnty., Wis. § 4.201(2) (2013).                            Consequently,
    the DNR's stated position in the present case——disavowing any
    consideration of the effects of water levels on the tax base——is
    directly contrary to the statutory and case law authority it
    relies on in the Decision.
    ¶142 In this case, the DNR considered riparian access and
    enjoyment when making the water level determination for Lake
    Koshkonong under 
    Wis. Stat. § 31.02
    (1) but excluded testimony on
    economic impacts of lower water levels on both riparian and non-
    riparian property owners and communities in close proximity to
    the   lake.      At    oral     argument,     the     DNR     claimed     that    economic
    66
    No.         2008AP1523
    interests were subsumed into the admitted testimony on riparian
    interests.
    ¶143 The DNR's Decision and current position relies on this
    court's       previous   opinion          in    Wisconsin's       Environmental           Decade
    when     it     characterized        the       evidence      of   economic         impacts     as
    "secondary or indirect economic impacts."43                            In that case, the
    court held that the DNR did not need to consider socioeconomic
    impacts in determining whether to issue an EIS in connection
    with     Wis.    Stat.   ch.    30    permits.          Wis.'s        Envtl.      Decade,

    ¶144 We disagree with the DNR's application of Wisconsin's
    Environmental        Decade      to        this      case.        First,          the    alleged
    socioeconomic        injuries        in    that      case——a      possible         decline     in
    downtown        Appleton's     business         because      of   a   new    shopping        mall
    outside of the city——did not have "a direct causal relationship
    to the minor changes to the physical environment found by the
    DNR."        
    Id. at 404
    .       Here, the decision to raise or lower water
    levels has a direct economic impact on the riparian community.
    Second, the case before us is not about issuing an EIS; this
    43
    Yet, the DNR did not exclude evidence of secondary
    economic loss entirely; the ALJ admitted testimony on the loss
    of board feet of green ash and diminished crop yields in
    drainage districts.   In fact, the testimony of diminished crop
    yields that would result from higher waters is an explicit
    finding of fact in the Decision.
    It is inconsistent for the DNR to consider the economic
    impacts of higher water level proposals like these, but refuse
    to consider economic impacts from lower water levels under the
    current order.

    case     is   about     what       the        DNR    should        consider      in   protecting
    property, as directed by 
    Wis. Stat. § 31.02
    (1), when making a
    water level determination.
    ¶145 It is important to note that the economic testimony
    excluded        at    the        contested          case     hearing       supplemented          the
    testimony of residents and business owners that the ALJ allowed
    to     stay   in.       In       other    words,           the     excluded      testimony       was
    different       from    the       testimony          that     the    ALJ    accepted.            The
    included testimony spoke to how long the piers of lake-based
    businesses       have       to    be     in    order        to     make    effective       use    of
    navigable water, while the excluded expert testimony of John
    Stockham spoke to the money lost by these businesses with water
    levels on Lake Koshkonong reduced from their historical levels.
    The included testimony covered riparian access and enjoyment,
    while     the    excluded          testimony         of     Stockham       and      Dr.    Kashian
    explained how property may have diminished in value or risen in
    value more slowly than comparable lake property because of the
    reduced access.             The included testimony spoke to the natural
    scenic beauty, hunting, fishing, camping, and boating on and
    around    Lake       Koshkonong,         while       the     excluded       testimony       talked
    about the overall economic impact that lower water levels would
    have     on     the     community         that           depends     on    these      enumerated
    activities——not only the impact on businesses but also on the
    municipalities          that       surround          the     lake.         The      DNR    rightly
    considered the direct impact of lower water levels on riparian
    properties, but wrongly excluded the cumulative economic effect
    of the lower water levels on these properties.                              It is a familiar
    68
    No.         2008AP1523
    principle of environmental law that secondary effects are often
    more substantial than the primary effects of an action.
    ¶146 The        DNR    asks    how    it    would     go     about       an     economic
    analysis:44         How       would   it    monetize        the    value        of    riparian
    property?        What would be its logical stopping point?                           We do not
    hold    that     the    DNR    must   consider        remote      economic       impacts;      a
    reasonableness standard should apply.                      The DNR has discretion as
    to which impacts are too attenuated to consider,45 and it can
    refute any economic evidence.                     Moreover, evidence of economic
    impacts     is    not     dispositive       in    a   water       level    determination;
    hypothetically, on remand the DNR could still reject a petition
    for    higher      water       levels       on    Lake      Koshkonong          even      after
    considering       the     economic      impacts       of    lower    water           levels   on
    property.        However, it is clear that the DNR must consider the
    economic impacts in the first place.
    44
    The DNR is capable of conducting an economic analysis in
    other contexts.     See, e.g., 
    Wis. Stat. §§ 285.01
    (12) and
    227.137.   However, we are not requiring the DNR to conduct an
    economic analysis, per se.   We hold that the DNR must consider
    economic impacts to property when making a water level
    determination under 
    Wis. Stat. § 31.02
    (1).
    Furthermore, the DNR asserts that it cannot consider
    economic impacts like property values on a proposed higher water
    level order.   This assertion would produce an absurd result in
    the case of a proposed lower water level order.       The DNR's
    narrow interpretation of "protect . . . property" would mean
    that only direct physical impacts to property could be
    considered but no evidence of ruined property values or business
    receipts could be considered.
    45
    It merits repeating that an ALJ must admit "all testimony
    having reasonable probative value, but shall exclude immaterial,
    irrelevant or unduly repetitious testimony or evidence."    
    Wis. Stat. § 227.45
    (1).
    69
    No.        2008AP1523
    ¶147 We make one further observation.                        Raising and lowering
    water levels, pursuant to 
    Wis. Stat. § 31.02
    (1), is a classic
    example of government regulation.                          A regulation may severely
    diminish the value of property, but in a regulatory "taking"
    under the Fifth Amendment, the "regulation or government action
    'must deny the landowner all or substantially all practical uses
    of a property in order to be considered a taking for which
    compensation      is        required.'"         Eberle       v.    Dane      Cnty.      Bd.    Of

    227 Wis. 2d 609
    , 622, 
    595 N.W.2d 730
     (1999).                                 If the
    economic impact of government regulation is not considered at
    the    time     the     regulation        is        initiated,       when       will     it    be
    considered?
    ¶148 We     conclude        that    the        DNR    erred       when      it   excluded
    testimony on economic impacts of lower water levels when making
    a water level determination under 
    Wis. Stat. § 31.02
    (1).
    III. CONCLUSION
    ¶149 The DNR's conclusions of law are subject to de novo
    review      because the        DNR's   water        level    order       under     
    Wis. Stat. § 31.02
    (1) is heavily influenced by the DNR's interpretation of
    the scope of its own powers, its interpretation of the Wisconsin
    Constitution,         its    disputed     interpretation            of    the      statute     it
    utilized, and its reliance upon statutes and rules outside of
    Wis. Stat. ch. 31.
    ¶150 The        DNR     properly         considered         the     impact        of    the
    Petition's proposed water levels on public and private wetlands
    in    and     adjacent       to   Lake     Koshkonong.               However,          the    DNR
    inappropriately        relied     on     the    public       trust       doctrine      for    its
    70
    No.      2008AP1523
    authority to protect non-navigable land and non-navigable water
    above the ordinary high water mark.                The DNR has broad statutory
    authority grounded in the state's police power to protect non-
    navigable      wetlands    and     other    non-navigable          water     resources.
    Thus,    the   DNR   may    consider       the    water    level       impact      on    all
    adjacent property under 
    Wis. Stat. § 31.02
    (1).
    ¶151 The DNR was entitled to consider the water quality
    standards in Wis. Admin. Code § NR 103, promulgated under Wis.
    Stat. ch. 281, when making a 
    Wis. Stat. § 31.02
    (1) water level
    determination.       By statute, the DNR is responsible for writing
    and enforcing wetland water quality standards in this state.
    Accordingly, it       would   be    unreasonable        for      the   DNR    to    ignore
    statutes and its own administrative rules when making a water
    level determination affecting wetlands.                   Therefore, the DNR may
    consider § NR 103 water quality standards when making a water
    level    determination     under     
    Wis. Stat. § 31.02
    (1)       that      affects
    wetlands and may apply these standards when appropriate after
    weighing    the     factors   in    the     statute.        However,         
    Wis. Stat. § 281.92
     suggests that the DNR is not required to apply ch. 281
    standards in making a determination under 
    Wis. Stat. § 31.02
    because ch. 31 is excepted from the provisions of ch. 281.
    ¶152 The    DNR   erroneously       excluded      most    testimony         on   the
    economic impact of lower water levels in Lake Koshkonong on the
    residents, businesses, and tax bases adjacent to and near Lake
    Koshkonong.        This evidence was relevant to the DNR's decision-
    making under 
    Wis. Stat. § 31.02
    (1).                Although the DNR is granted
    substantial discretion in its decision-making under the statute,
    71
    No.     2008AP1523
    it must consider all probative evidence when its decision is
    likely to favor some interests but adversely affect others.                In
    this case, the DNR's exclusion of most economic evidence was
    inconsistent with its acceptance of competing economic evidence
    that helped sustain its water level decision.
    By   the   Court.—The   decision   of   the   court   of    appeals   is
    reversed and the cause is remanded to the circuit court for
    further proceedings consistent with this opinion.

    ¶153 N.      PATRICK      CROOKS,         J.      (dissenting).                This        case
    presents a question that the majority can——indeed does——answer
    by   interpreting      
    Wis. Stat. § 31.02
    (1)      (2009-10).              Yet    the
    majority     unnecessarily           reaches          out    to     the       constitutional
    principle     of    the     public    trust          doctrine       from      the        Wisconsin
    Constitution,       constricting          the       doctrine      and       misreading           this
    court's precedent, especially the well-settled law articulated
    in   Just   v.     Marinette    County,         
    56 Wis. 2d 7
    ,    
    201 N.W.2d 761
    (1972).     Wisconsin's long and robust history of protecting the
    public trust is widely acknowledged and respected.                                   The public
    trust doctrine imposes on the state, as trustee, the affirmative
    duty to protect, preserve, and promote the public's right to
    Wisconsin's waters.
    ¶154 The       majority     opinion            attempts       to       undermine           this
    court's     precedent,      recharacterize             its     holdings,           and     rewrite
    history.      Instead of limiting itself to addressing only what
    must be addressed, the majority seizes this opportunity to limit
    the public trust doctrine in an unforeseen way, transforming the
    state's     affirmative duty         to    protect          the   public          trust    into    a
    legislative choice.           It needlessly unsettles our precedent and
    weakens     the    public    trust     doctrine         that      is       enshrined       in    the
    Wisconsin     Constitution.           This          represents         a    significant          and
    disturbing shift in Wisconsin law.
    ¶155 The      majority     also      errs        in    expanding            the     type    of
    evidence that the Department of Natural Resources (DNR) must
    consider in these cases.               A straightforward interpretation of
    1
    No.     2008AP1523.npc
    
    Wis. Stat. § 31.02
    (1)        would      not    require     the    DNR      to    consider
    secondary or indirect economic impact when making water level
    determinations.          The economic evidence admitted during the ten-
    day contested case hearing was sufficient to discharge the DNR's
    duty to "protect . . . property," and the excluded evidence was
    not relevant or required.                 The DNR has a difficult job to do
    under this statute, and in this case, the DNR did it well.                                   The
    decisions     of   the     DNR,    the       circuit      court,     and   the       court    of
    appeals each properly concluded that § 31.02(1) does not require
    consideration       of    such    secondary        or     indirect    economic            impact.
    The fact is that the DNR sufficiently considered the protection
    of   property,     and    therefore,         it    was    not   error      to      strike    the
    secondary or indirect economic evidence that it struck.
    ¶156 For these reasons, I respectfully dissent.
    I. WISCONSIN COURTS HAVE AGGRESSIVELY PROTECTED THE PUBLIC
    TRUST DOCTRINE.
    ¶157 To      understand          the     significance          and      to     see     the
    potential implications of the majority's novel interpretation of
    the Just case, it is necessary to appreciate how settled the
    public trust doctrine has been in Wisconsin until now.                                      This
    court highlighted the constitutional basis of the public trust
    doctrine in Muench v. Public Service Commission, 
    261 Wis. 492
    ,
    
    53 N.W.2d 514

    261 Wis. 492
    ,    
    55 N.W.2d 40
    (1952).       In that case, the court traced the history of the
    public    trust     doctrine       to    the       Northwest       Ordinance         of    1787.
    Muench,   261      Wis.    at    499.        The    language       from    the       Northwest
    2
    No.   2008AP1523.npc
    Ordinance   of      1787   was   then     adopted       by   the    territorial
    constitutional      convention   in     1848,   approved       by   an     act   of
    Congress    which     admitted    Wisconsin          into    the    Union,       and
    incorporated in the Wisconsin Constitution as follows:
    The state shall have concurrent jurisdiction on all
    rivers and lakes bordering on this state so far as
    such rivers or lakes shall form a common boundary to
    the state and any other state or territory now or
    hereafter to be formed, and bounded by the same; and
    the river Mississippi and the navigable waters leading
    into the Mississippi and St. Lawrence, and the
    carrying places between the same, shall be common
    highways and forever free, as well to the inhabitants
    of the state as to the citizens of the United States,
    without any tax, impost or duty therefor.
    Wis. Const. art. IX, § 1.
    ¶158 Early on, this court declared that the public trust
    not only required preservation of the trust, it also required
    promotion of it.      City of Milwaukee v. State, 
    193 Wis. 423
    , 449,
    
    214 N.W. 820
     (1927) ("The equitable title to these submerged
    lands vests in the public at large, while the legal title vests
    in the state, restricted only by the trust, and the trust, being
    both active and administrative, requires the lawmaking body to
    act in all cases where action is necessary, not only to preserve
    the trust, but to promote it." (emphasis added)).
    ¶159 In     Diana     Shooting     Club    v.     Husting,     this     court
    described the state's responsibilities under the public trust
    doctrine:
    The wisdom of the policy which, in the organic laws of
    our state, steadfastly and carefully preserved to the
    people the full and free use of public waters cannot
    be questioned. Nor should it be limited or curtailed
    by narrow constructions. It should be interpreted in
    the broad and beneficent spirit that gave rise to it

    in order that the people may fully enjoy the intended
    benefits.

    , 271, 
    145 N.W. 816
     (1914)
    (emphasis added).
    ¶160 The court in Muench adopted the language from Diana
    Shooting Club and demonstrated the growth of the public trust
    doctrine over time by describing its own holding as "keeping
    with   the     trend      manifested       in    the      development          of    the    law    of
    navigable      waters       in    this    state      to    extend     the       rights      of    the
    general public to the recreational use of the waters in this
    state,    and    to       protect    the    public         in   the       enjoyment        of    such
    rights."       Muench, 261 Wis. at 512.
    ¶161 This          court     in    Just       v.    Marinette           County      further
    interpreted         the    doctrine       while      upholding        a    shoreland        zoning
    statute enacted pursuant to the state's public trust duty.                                        The
    court stated:
    The active public trust duty of the state of Wisconsin
    in respect to navigable waters requires the state not
    only to promote navigation but also to protect and
    preserve those waters for fishing, recreation, and
    scenic beauty. To further this duty, the legislature
    may   delegate  authority   to  local  units  of   the
    government, which the state did by requiring counties
    to pass shoreland zoning ordinances.
    Just, 
    56 Wis. 2d at 18
     (emphasis added) (citations omitted).
    This court explained that the purpose of the statute at issue in
    that case was to "protect navigable waters and the public rights
    therein      from    the    degradation          and      deterioration          which     results
    from uncontrolled use and development of shorelands."                                       
    Id. at 10
    .       We    noted       that    the     stated         purpose        of     the    shoreland
    regulation program is to "aid in the fulfillment of the state's
    4
    No.    2008AP1523.npc
    role as trustee of its navigable waters and to promote public
    health, safety, convenience and general welfare."                      
    Id.
    ¶162 Since then this court has consistently reiterated the
    purpose and the significance of the public trust doctrine in its
    cases.      For example, Wisconsin's Environmental Decade, Inc. v.
    DNR (Environmental Decade 1978), described the duties of the
    state under the public trust as "not only to promote navigation
    but    also    to    protect      and    preserve     its    waters      for    fishing,
    hunting, recreation, and scenic beauty."                    Envtl. Decade 1978, 
    85 Wis. 2d 518
    ,   526,   
    271 N.W.2d 69
       (1978).      We   described       the
    state's responsibility as long-acknowledged and highlighted the
    legislature's        delegation     of    water      management    to     the    DNR   in
    furtherance of "the state's affirmative obligations as trustee."
    
    Id. at 526-27
    .
    ¶163    Recently, this court reiterated these principles in
    Lake Beulah Management District v. DNR, holding that under the
    applicable statutes and the public trust duties, the DNR can and
    must consider whether an inland well would harm waters of the
    state before issuing a permit for the well.                      Lake Beulah, 
    2011 WI 54
    , ¶3, 
    335 Wis. 2d 47
    , 
    799 N.W.2d 73
    .                      This court explained
    jurisprudence on the public trust doctrine:
    We reaffirmed this maxim in Muench v. Public Service
    Commission in our examination of the history and
    evolution   of  the   public   trust   doctrine, which
    indicated a "trend to extend and protect the rights of
    the public to the recreational enjoyment of the
    navigable waters of the state." We have further
    explained, "The trust doctrine is not a narrow or
    crabbed concept of lakes and streams."
    Id., ¶31 (emphasis added) (citations omitted).

    ¶164 Our cases demonstrate that the scope of the public
    trust doctrine is such that the state holds title to the land
    between    the     ordinary    high    water       marks,     and    state     regulation
    consistent with the public trust doctrine extends to surrounding
    areas.     The ownership of land was emphasized in Diana Shooting
    Club, which was a case about trespass.                      In that case, there was
    no trespass because the hunter was hunting between the ordinary
    high water marks, land that was held in trust for the public.
    Diana Shooting Club, 156 Wis. at 272.                       In contrast, regulation
    consistent with the public trust doctrine was at issue in Just
    because the shoreland zoning statute extended well beyond the
    ordinary high water mark, and the court held that it could be
    regulated pursuant to the public trust doctrine.                         Just, 
    56 Wis. 2d at 14, 17
    .
    ¶165 In        furtherance           of         the       state's          trustee
    responsibilities,       the     legislature           has     enacted        statutes    to
    discharge its duties.           As the court explained in Environmental
    Decade     1978,     several    chapters         of     the     Wisconsin       statutes,
    including    Chapter    31,     which      is    at   issue     in   this     case,     were
    enacted "[i]n furtherance of the state's affirmative obligations
    as trustee of navigable waters."                   
    85 Wis. 2d at 527
    .            We dealt
    with a similar situation in this court's unanimous decision in
    Lake   Beulah,      where     the    legislature        had     used     a    statute    to
    implement its public trust duties.                      This court stated, "[W]e
    conclude    that,    through        
    Wis. Stat. §281.11
        and    §    281.12, the
    legislature has delegated the State's public trust duties to the
    DNR in the context of its regulation of high capacity wells and
    6
    No.   2008AP1523.npc
    their potential effect on navigable waters such as Lake Beulah."
    Lake    Beulah,    
    335 Wis. 2d 47
    ,   ¶34    (emphasis       added).         That
    decision     dealt    with     non-navigable         water,    and     explained       its
    relationship to the public trust doctrine.                    The statutes created
    to preserve and promote the public trust doctrine allowed the
    regulation    of     non-navigable        waters     because    of     the    potential
    effects non-navigable waters have on navigable waters.
    II.     THE MAJORITY UNNECESSARILY UNDERMINES WELL-SETTLED LAW ON
    WISCONSIN'S PUBLIC TRUST DOCTRINE.
    ¶166 The      heart    of   the    public      trust    doctrine        lies    in
    protecting,    preserving,         and    promoting     the    public's       right    to
    Wisconsin's waters, and this court has vigilantly guarded these
    rights.     The public trust doctrine entrusts to the state the
    duty to protect, preserve, and promote the public trust.                              The
    majority    untethers        our   constitutional       jurisprudence         from    its
    foundation and attempts to transform 165 years of constitutional
    precedent into a mere legislative exercise of the state's police
    power.     The citizens of Wisconsin may rightly wonder why the
    majority is limiting the protection of Wisconsin's waters and
    reaching a constitutional question that is not essential to its
    holding.     I refuse to unnecessarily constrict our holdings on
    7
    No.    2008AP1523.npc
    this       important    constitutional        doctrine,        especially         in    a   case
    that should be decided on statutory grounds.1
    ¶167 The central issue in this case is one of statutory
    interpretation——namely,          whether          the    DNR   can      consider       wetlands
    above the ordinary high water mark when determining water levels
    under 
    Wis. Stat. § 31.02
    (1).              Wisconsin Stat. § 31.02(1) states
    in relevant part: "The department, in the interest of public
    rights in navigable            waters    or       to    promote       safety     and    protect
    life, health and property[,] may regulate and control the level
    and flow of water in all navigable waters . . . ."                                     Both the
    majority       and    the   petitioner    agree         that      a    simple     reading    of
    § 31.02(1)           demonstrates       that           the     statute          allows      for
    consideration          of   private   wetlands.              In       fact,     the    majority
    1
    Two other issues are decided by the majority. The first
    is the standard of review.           The majority lays out the
    appropriate framework to determine the standard of review.        It
    then determines that the standard of review here should be de
    novo review because it believes that the DNR has not
    consistently interpreted 
    Wis. Stat. § 31.02
    (1) and that the
    question presented is one of the scope of the DNR's power.
    Majority op., ¶¶58-64.    Because I would reach the same result
    under any level of deference, I will not address the majority's
    application of the oft-cited rules from Racine Harley-Davidson,
    Inc. v. State, 
    2006 WI 86
    , 
    292 Wis. 2d 549
    , 
    717 N.W.2d 184
    . See
    also Hilton ex rel. Pages Homeowners' Ass'n v. DNR, 
    2006 WI 84
    ,
    
    293 Wis. 2d 1
    , 
    717 N.W.2d 166
     (discussing the standard of review
    of an agency decision in a case related to the public trust
    doctrine).      Even   applying   de    novo   review,   the   DNR's
    interpretations   were   reasonable    and   should   therefore   be
    affirmed.
    The second issue           decided by the majority is whether 
    Wis. Stat. § 281.92
     bars             the DNR from considering water quality
    standards from Wis.            Admin. Code § NR 103 when making its
    determination under §          31.02(1). I agree with the majority that
    
    Wis. Stat. § 281.92
                  does not bar the DNR from such a
    consideration.
    8
    No.    2008AP1523.npc
    states:       "The     District    acknowledges      that    'privately        owned
    wetlands       are   entitled     to   consideration   as    "property"       to   be
    protected in establishing a water level order.'                 There can be no
    dispute that the DNR can 'consider' water level impact on all
    adjacent property under 
    Wis. Stat. § 31.02
    (1)."                       Majority op.,
    ¶109.       Because that interpretation is dispositive of the issue,
    I would stop the analysis there.
    ¶168 Instead, the majority reaches that conclusion and then
    embarks on a constitutional analysis in which it reads the part
    of the statute before the "or" to be a direct enactment of the
    public trust doctrine and the part after the "or" as an exercise
    of police powers.           Majority op., ¶¶102-103.        It speculates as to
    how the statute could have been written so it "would be seen as
    a direct enforcement mechanism for the public trust in navigable
    waters" while explaining that the actual language could not be a
    direct enforcement mechanism.              Majority op., ¶103.         The majority
    does not cite any cases that interpret 
    Wis. Stat. § 31.02
    (1) the
    way it does now, and it ignores the cases that suggest that the
    entire statute is an embodiment of the public trust doctrine.2
    Reading the statute as the majority does attempts to strip the
    state, trustee of the public trust doctrine, of the ability to
    regulate anything that is not between the ordinary high water
    marks       pursuant   to   the   public    trust   doctrine.         The   majority
    reaches a constitutional issue that it is not required to reach,

    and it engages in a strained analysis to bolster its holding.
    Both 
    Wis. Stat. § 31.02
    (1) and the long-settled public trust
    doctrine    support       a    consideration          of     the       impact        on     wetlands
    adjacent     to    Lake       Koshkonong           when     regulating              water    levels
    pursuant to the public trust doctrine.
    ¶169 To support its holding, the majority misconstrues Just
    v.   Marinette     County.          The    majority        calls        the     Just        case   "a
    textbook example of using the state's police power [as opposed
    to using the constitutional public trust doctrine] to support
    legislation 'to protect navigable waters and the public rights
    therein . . . .'"             Majority op., ¶96.                 The majority uses this
    interpretation      of    Just to          explain        that    the    statute          at issue
    here,     § 31.02(1),         is    only      half   based        on     the        public     trust
    doctrine;    the    rest,          as   the   majority       would       have        us     believe,
    derives only from the state's police power and is disconnected
    3
    from the public trust doctrine.
    3
    Although it does not answer why it matters in this case,
    the majority leaves no doubt about the significance of its novel
    interpretation of the Just case, namely that it changes the ease
    with which the legislature can modify regulation and creates a
    more lenient legal standard for this court to apply when it
    reviews such changes:
    The police power is potent, and legislation grounded
    in the state's police power is presumed constitutional
    and   will   be   sustained   unless   it   is   deemed
    unconstitutional    beyond    a    reasonable    doubt.
    Nonetheless, as Just makes clear, the distinction
    between the DNR's constitutionally based public trust
    authority and the DNR's police power-based statutory
    authority   is   that   the  latter   is   subject   to
    constitutional and statutory protections afforded to
    property, may be modified from time to time by the
    legislature, and requires some balancing of competing
    interests in enforcement.

    ¶170 The   clear   language   of   Just   rebuts    the     majority's
    conclusion that it was only a police power case.4            The thrust of
    Majority op., ¶101.      In other words, rights that are not
    protected by the constitution are easier to take away.      In
    addition, the majority's interpretation transforms what was an
    affirmative duty on the state as trustee into a right to
    regulate when the legislature chooses to do so, allowing the
    state to ignore its duty with respect to things that impact
    navigable waters but are not physically located between the
    ordinary high water marks.

    this court extended the public trust doctrine through Just to
    allow for regulation above the ordinary high water mark.     See,

    the Just opinion showed that the court believed it was relying

    mark——and        applies      it    to    support     its   subsequent            conclusion.5
    Regarding Just, it states:
    If there is any question that the court was not
    relying on the public trust doctrine to sustain the
    shoreland   zoning   ordinance  and   its  authorizing
    legislation, the court noted that the Marinette County
    ordinance applied to "lands within 1,000 feet of the
    normal high-water elevation of navigable lakes, ponds,
    or flowages and 300 feet from a navigable river or
    stream."   These dimensions far exceed the geographic
    limitations of public trust jurisdiction.
    Majority     op.,      ¶100      (citation      omitted).         The    majority's         only
    apparent support for its conclusion about the dimensions of the
    public trust jurisdiction comes from its own earlier analysis.
    The Just case establishes the opposite conclusion——that the DNR
    pursuant to the public trust doctrine may consider the impact on
    land above the ordinary high water mark.
    ¶172 Not only does an appropriate interpretation of Just
    rebut      the    majority's        conclusions,       this    court        has     repeatedly
    interpreted        the    public     trust      doctrine      more      broadly      than    the
    majority does today, and there is no compelling reason presented
    in this case to change that interpretation.                           See supra, ¶¶161-
    165.       The case law indicates that the state has the power to
    regulate         lands     beyond        the    ordinary      high       water       mark     in
    discharging the duties entrusted to it under the public trust
    doctrine.          See,     e.g.,        Lake   Beulah,     
    335 Wis. 2d 47

    affirmative duty as trustee to protect and promote the public
    trust.       See, e.g., City of Milwaukee, 
    193 Wis. at 449
    .
    ¶173 One explanation for the majority's puzzling holding is
    that it appears to confuse the concepts of ownership of (or
    title to) the land with regulation pursuant to the public trust
    doctrine.       In   the   cases    the   majority      cites    to    support   its
    position that public trust jurisdiction is confined to limited
    geographic       areas,     the    idea   of   ownership    of    the     land   was
    paramount, but here, ownership of the private wetlands is not at
    issue.6       The issue is only whether the DNR has the authority
    under the public trust doctrine to consider the impact on those
    adjacent wetlands consistent with its duties under the public
    trust       doctrine.      After citing    cases   it    believes      support   its
    proposition that the public trust doctrine is limited to water
    between the ordinary high water marks, the majority explains the
    problem it sees:
    Contemplating the question of ownership is important
    because the public trust doctrine implicates state
    ownership or virtual state ownership——by virtue of its
    trust responsibility——of land under navigable waters.
    If the public trust were extended to cover wetlands
    that are not navigable, it would create significant
    new questions about ownership of and trespass on
    private land, and it would be difficult to cabin
    expansion of the state's new constitutionally based
    jurisdiction over private land.

    Majority op., ¶84.       The quotation from the majority demonstrates
    its misunderstanding of the argument of the DNR.                          The DNR in
    this case was not asserting that the public trust doctrine gives
    the state ownership of the private wetlands; rather it argues
    that the public trust doctrine allows the DNR to consider the
    impact on the wetlands when determining water levels.                       It quotes
    the Just court's statement that "[l]ands adjacent to or near
    navigable waters . . . are subject to the state public trust
    powers"   and    emphasizes       the   Just      decision's   reference      to   the
    wetlands "adjacent to" not "within" navigable waters.
    ¶174 Allowing       the      trustee    to    discharge   its      public   trust
    duties by considering things that affect navigable waters is
    consistent with our precedent.               If it could not, how then would
    the state discharge its extensive duties "not only to promote
    navigation      but   also   to    protect       and   preserve   its     waters   for
    fishing, hunting, recreation, and scenic beauty"?                       Envtl. Decade

    85 Wis. 2d at 526
     (citations omitted).                   Therefore, the DNR
    did not err in relying on its public trust power to consider the
    impact of raising the water levels on adjacent private wetlands
    even when the wetlands are above the ordinary high water mark.
    The conclusion the majority reaches is a novel interpretation
    that cannot be squared with the extensive public trust doctrine
    case law.

    § 31.02(1) DOES NOT REQUIRE ADMISSION OF THE STRICKEN
    EVIDENCE.

    ¶175 Despite acknowledging that the decision adopted by the
    DNR was "meticulous [and] comprehensive," the majority reverses,
    holding           that      the      DNR   was    required       to     consider     additional
    evidence          on     the      secondary      or     indirect      economic     impacts      of
    raising the water level when making its determination under 
    Wis. Stat. § 31.02
    (1).7                 Because I do not believe the statute requires
    the DNR to consider the evidence that was stricken to discharge
    its duty to "protect . . . property," I dissent.
    ¶176 During               the      ten-day      contested         case     hearing,      a
    significant amount of evidence was heard.                             The parties presented
    testimony and other evidence related to the economic impact of
    the    change          in    the      water   level,      including        testimony      on   the
    implications for navigation, information about the impact on use
    and enjoyment of riparian property by riparian owners, impact on
    fish        and    fowl,       and      information      about    the     impact    on    natural
    beauty and recreation.                      Some evidence was later stricken from
    the record on               the grounds          that    the    "[s]econdary       or    indirect
    economic impacts of a water level determination do not bear on
    the statutory               standard set         forth    in     section    31.02(1)."         The
    stricken evidence included testimony and exhibits from experts
    who testified as to the potential economic effects of the water
    level        determination            on   residential         property     values,      business
    incomes,           and      tax      revenues.          However,      the    DNR's       decision
    7
    The majority holds: "We find that history, purpose,
    precedent, and the DNR's past practice support a broad
    interpretation of the phrase 'protect . . . property' so that
    the DNR is not limited to consideration of hydrologic damage to
    real property and riparian rights when making a water level
    determination under 
    Wis. Stat. § 31.02

    owner's interests in their property:
    The diminished ease of access experienced by many
    riparians and their desire for higher water levels,
    reflects their diminished utility and enjoyment of
    their property, which doubtless reduces the value of
    that property to them.    This diminished utility and
    enjoyment of the property, and the expectation that
    higher water would enhance the utility and enjoyment
    of riparian property, has been considered and weighed
    under the standards of 
    Wis. Stat. § 31.02
    (1).
    (Emphasis added).
    ¶177 As         explained      above,        
    Wis. Stat. § 31.02
    (1)        states:
    "The department, in the interest of public rights in navigable
    waters     or    to    promote       safety        and    protect          life,    health        and
    property[,] may regulate and control the level and flow of water
    in   all   navigable          waters      .   .    .     ."      
    Wis. Stat. § 31.02
    (1)
    (emphasis       added).        The     majority          focuses      on    "protect        .    .   .
    property" and interprets it to mean that striking the secondary
    or   indirect      economic       impact          evidence      constituted           reversible
    error.     The more reasonable interpretation of the statute, as
    demonstrated by the quotation set forth above, is that the DNR
    sufficiently considered the protection of property when making
    its determination under 
    Wis. Stat. § 31.02
    (1).
    ¶178 In         other    statutes       that        the    DNR       administers,           the
    legislature        has    specifically            included         language         about        such
    economic impact, whereas in § 31.02(1) the legislature has not
    signaled that the DNR must consider such secondary or indirect
    economic        impact.        For     example,          
    Wis. Stat. § 30.195
    (2)(c)2
    requires    consideration            of    whether        the    proposed          change       "will
    improve    the     economic       or      aesthetic        value      of     the    applicant's

    consider "energy, economic and environmental impacts and other
    costs"       to     determine    air-pollution          regulation.        The     DNR's
    permitting process for dams under 
    Wis. Stat. § 31.06
    (3)(b) looks
    at whether the proposal is "in the public interest, considering
    ecological, aesthetic, economic and recreational values."                              None
    of this language is present in 
    Wis. Stat. § 31.02
    (1).                            If the
    legislature intended that the DNR must consider such secondary
    or indirect economic impact, the legislature would have drafted
    the statute to signal such a requirement.8
    ¶179 As the court of appeals aptly observed, the District's
    interpretation,         now   adopted      by    the   majority,    has    no    logical

    .                      If it is reversible
    error       not    to   consider    this    type       of    secondary    or    indirect
    economic      impact,     what     evidence       is   the    fact-finder,       in     its
    discretion, allowed to exclude?                  The court of appeals explained
    this problem:
    For example, it is unclear under the District's
    construction  whether   the  DNR's  consideration  of
    economic effects on real property would be limited to
    property values of riparian owners or would also
    include the values of adjacent or area properties not
    situated directly on the lake. Similarly, if the DNR
    were required to consider revenues of businesses
    directly linked to lake recreational activities, like
    8
    Further support for this proposition is found in the
    majority's explanation of zoning ordinances which explicitly
    require a consideration of the "tax base" when making zoning
    decisions. Majority op., ¶141. Wisconsin Stat. § 31.02(1)

    marinas and bait shops, would it also be required to
    consider revenues of businesses with less direct links
    to use of navigable waters, such as gas stations and
    convenience stores?

    unnecessary layer of confusion for the DNR when reviewing these
    cases.
    ¶180 Instead        of    applying    the    governing       statute   or   this
    court's interpretation of similar statutes, the majority relies
    on language from Railroad Commission cases from the early 1900s
    to support its conclusion that the legislature in 1915 did not
    intend to exclude riparian rights from consideration in 
    Wis. Stat. § 31.02
    (1), and that therefore, it was reversible error to
    exclude evidence of such secondary or indirect economic impact
    to   water   level       changes.9        The    language    in    these    Railroad
    Commission decisions, on closer examination, supports the DNR's
    position     that        the     duty     to     protect     property       requires
    consideration       of    only    physical      impacts     on    property.       The
    9
    The majority also relies on a legislative report from
    1910, Report of the Comm. on Water Powers, Forestry, and
    Drainage of the Wis. Leg. 1910, 49th Leg., which explained that
    land near the shores of lakes was becoming very valuable.    See
    majority op., ¶135. The majority then states: "In light of the
    legislative reports giving rise to the Water Powers Act
    containing the 'protect . . . property' language of 
    Wis. Stat. § 31.02
    (1), one can reasonably infer that riparian residential
    property and lake-based businesses were prime considerations for
    protecting property." Id., ¶136. The majority fails to connect
    the observations in the legislative report with its "reasonable
    inference." One could just as reasonably infer that protection
    from physical damage to lakeshore property was the prime
    consideration for including language about protecting property
    in the statute and that the legislature did not expect the
    Railroad Commission to consider such secondary or indirect
    economic impact from changing water levels.

    stated: "[t]his level will not endanger life or health . . .
    [i]t will, however, affect property and overflow a large acreage
    of land . . . ."               Id. at 716.           The majority explains that the
    Railroad      Commission's         decision         "did    not     explicitly      limit      the
    protection         of     property       to     only       direct       physical     impacts."
    Majority op., ¶137.                The absence of an explicit limitation is
    not evidence that the statute requires consideration of such
    secondary or indirect economic impact; it is the natural result
    of    the    fact       that    Bear    Lake     was   about       physical      flooding       of
    property.
    ¶182 The other Railroad Commission case, In re Determining
    the High Water Mark to be Established on the Rest Lake Reservoir
    Operated      by    the        Chippewa       and    Flambeau         Improvement       Co.,    16
    W.R.C.R. 727, 731 (1915), considered Rest Lake's water level,
    and like the Bear Lake decision, involved severe physical damage
    20
    No.    2008AP1523.npc
    to    property.    The    Chippewa          &    Flambeau       Improvement          Company
    requested    permission       from    the       Railroad       Commission       to    adopt
    certain high and low water marks, but property owners vigorously
    protested——arguing      that    the    wide          variation     in     water      levels
    negatively affected their property.                    Id. at 731.        The Railroad
    Commission    agreed    with    property         owners     that    the     "disastrous
    effects upon shore property are only too plainly visible" from
    such a great variation in the water level.                         Id. at 734.            It
    described the consequences as follows:
    Banks are lined with dead trees, logs, rocks and
    debris in an effort to prevent the shore lines from
    being obliterated. . . .     When the banks give away
    large trees fall into the water.      In one instance,
    thirty large green timber trees were counted lying in
    the lake where the shore had been taken away this
    year. . . .     In places the old shore lines have
    disappeared . . . . The gradual disappearance of what
    are now islands was fully shown by the testimony.
    Id.    While the Railroad Commission briefly mentioned that large
    sums of money were used to improve private homes along the lake,
    its ultimate reason for protecting this property was concern for
    potential    physical    damage      rather       than     secondary       or   indirect
    economic     impact.      In    denying          the     petition,        the   Railroad
    Commission found, "[t]he effect of [the proposed water level]
    will be to give a very wide variation in levels, tending to
    destroy the shore line and property around the lakes."                               Id. at
    738   (emphasis   added).        Neither        of     these    cases     supports      the
    majority's conclusion about the legislative intent in 1915.
    ¶183 Further,     the    majority         minimizes       this      court's      past
    interpretation     of     similar      statutory           language,        which       has
    explicitly limited its reading to a narrow interpretation of the
    21
    No.   2008AP1523.npc
    language.     In City of New Lisbon v. Harebo, this Court held that
    a dam may "endanger property" when "by reason of its location,
    or manner of construction, or the character of the soil upon
    which it is built . . . it [would] tend to flood cities or
    villages or [would be] likely to give way and create havoc and
    destruction below the dam . . . ."              New Lisbon, 
    224 Wis. 66
    , 73,
    
    271 N.W. 659
     (1937).          We made sure to point out that "we are of
    the opinion that this is as much as the section can be held to
    mean."      
    Id.
       Thus, this court expressly limited the construction
    of    "endanger    property,"    and    concluded     that   a    dam     would    not
    endanger     property    if    injury      to   the   property     resulted       from
    "normal flowage by the ordinary operation of the dam."                     
    Id.
        The
    court's narrow reading of "endanger property" as applying to
    only physical damage and hydrologic events supports a limited
    reading of "protect . . . property" in 
    Wis. Stat. § 31.02.10
    ¶184 It is illogical and contrary to the plain meaning of
    the    statute    to   hold,    as   the     majority   does,      that    language
    referring to "protect[ing] life, health and property" requires
    the DNR to consider such secondary or indirect economic impacts.
    10
    Another case that provides support for the conclusion
    that such secondary or indirect economic impact is not required
    to be considered is Wisconsin's Environmental Decade, Inc., v.
    DNR (Environmental Decade 1983), 
    115 Wis. 2d 381
    , 
    340 N.W.2d 722
    (1983). In Environmental Decade 1983, this court held that the
    DNR did not need to consider socioeconomic impact in determining
    whether it needed to issue an environmental impact study in
    connection with a permit.        
    Id. at 395
    .       While it is
    distinguishable on its facts (as noted by the majority), I agree
    with the DNR decision's assessment that this court's reasoning
    in Environmental Decade 1983 "applies with similar force here,
    even though that case involved action by the DNR under Chapter
    30, not Chapter 31, Stats."
    22
    No.    2008AP1523.npc
    It is apparent that the cases relied on by the majority do not
    lead to its conclusion.                  Further, contrary to the majority's
    position, the plain language is clear and certainly does not
    compel the majority's conclusion.                         The fact is that the DNR
    sufficiently            considered       the       protection         of      property,        and
    therefore,         I   conclude    that       it    was    not    error       to     strike    the
    secondary or indirect economic evidence that it struck.
    IV.    CONCLUSION
    ¶185    This case presents a question that the majority can——
    indeed does——answer by interpreting 
    Wis. Stat. § 31.02
    (1).                                    Yet
    the   majority         unnecessarily      reaches         out    to    the     constitutional
    principle      of       the    public    trust       doctrine         from     the     Wisconsin
    Constitution,           constricting      the       doctrine      and      misreading         this
    court's precedent, especially the well-settled law articulated
    in    Just    v.       Marinette   County.           Wisconsin's           long      and   robust
    history of protecting the public trust is widely acknowledged
    and respected.           The public trust doctrine imposes on the state,
    as    trustee,         the    affirmative      duty       to    protect,       preserve,      and
    promote the public's right to Wisconsin's waters.
    ¶186 The         majority     opinion         attempts         to     undermine        this
    court's       precedent,        recharacterize         its       holdings,          and    rewrite
    history.        Instead of limiting itself to addressing only what
    must be addressed, the majority seizes this opportunity to limit
    the public trust doctrine in an unforeseen way, transforming the
    state's      affirmative duty to               protect     the    public           trust   into   a
    legislative choice.              It needlessly unsettles our precedent and
    23
    No.    2008AP1523.npc
    weakens    the    public      trust    doctrine      that     is       enshrined      in    the
    Wisconsin    Constitution.             This       represents       a     significant        and
    disturbing shift in Wisconsin law.
    ¶187 The         majority      also     errs    in    expanding           the   type       of
    evidence     that      the    DNR     must    consider       in     these       cases.           A
    straightforward interpretation                of    
    Wis. Stat. § 31.02
    (1) would
    not require the DNR to consider secondary or indirect economic
    impact when making water level determinations.                                 The economic
    evidence admitted during the ten-day contested case hearing was
    sufficient       to    discharge      the    DNR's    duty     to       "protect      .     .    .
    property,"       and    the    excluded       evidence       was        not    relevant         or
    required.     The DNR has a difficult job to do under this statute,
    and in this case, the DNR did it well.                        The decisions of the
    DNR, the circuit court, and the court of appeals each properly
    concluded that § 31.02(1) does not require consideration of such
    secondary or indirect economic impact.                     The fact is that the DNR
    sufficiently          considered      the     protection           of     property,         and
    therefore, it was not error to strike the secondary or indirect
    economic evidence that it struck.
    ¶188 For the foregoing reasons I respectfully dissent.
    ¶189 I am authorized to state that Chief Justice SHIRLEY S.
    ABRAHAMSON and Justice ANN WALSH BRADLEY join this dissent.
