    Goff, Justice.
    The Dam Safety Act gives the Indiana Department of Natural
    Resources (the “DNR”) jurisdiction over certain dams in, on, or along
    streams in Indiana to protect Hoosiers’ lives and property. The Moriaritys
    have a large pond and related dam on their land, and, since the early
    2000s, the DNR has tried to exercise jurisdiction over the dam based on its
    determination that the dam was located in, on, or along a stream. The
    Moriaritys have resisted the DNR’s jurisdiction and contested its findings
    without much success in the administrative tribunals and courts below.
    They now appeal to this Court, presenting us with three different
    questions. First, did the DNR properly exercise jurisdiction over the dam?
    Within this question lie issues concerning the reasonableness of the DNR’s
    definition of the word stream and what, if any, notice the Moriaritys had
    of that definition. Second, did the DNR present substantial evidence
    supporting its classification of the dam as a high-hazard dam? Third, can
    the Moriaritys modify their dam to remove it from DNR’s future
    jurisdiction? We answer each of these questions in the affirmative, largely
    based on our standard of review, and affirm the trial court.
    Factual and Procedural History
    In the late 1990s, Mae (“Becky”) and John Moriarity decided to build a
    pond on farm land they owned in Grant County. Before excavating and
    building the necessary embankments, they contacted various local, state,
    and federal agencies and obtained what they were told were the necessary
    permits. By 2000, after a few years of work, the Moriaritys ended up with
    a fairly large pond and related dam. Their pond covered between thirty
    and forty acres and contained at least one hundred acre-feet of water, and
    parts of the dam holding back this water were taller than twenty feet.
    By 2002, the DNR was aware of the pond and dam. Throughout the
    early 2000s, the DNR sought to have the Moriaritys correct what it
    considered “significant safety deficiencies” in the dam according to
    Indiana Code chapter 14-27-7.5 (the “Dam Safety Act” or the “Act”). See
    Appellee’s App. Vol. V, pp. 237, 239. On May 14, 2012, the DNR issued
    Indiana Supreme Court | Case No. 18S-PL-00296 | January 3, 2019   Page 2 of 17
    Notice of Violation VTS-3933-DM (the “NOV”) to the Moriaritys,
    describing numerous violations of the Dam Safety Act. The NOV ordered
    the Moriaritys to make certain changes to their pond and dam, imposed
    $35,000 in civil penalties for past violations, and provided daily penalties
    for any continuing violations.
    The Moriaritys petitioned for administrative review of the NOV. Two
    administrative law judges held a multi-part fact-finding hearing over the
    course of several months at which the parties presented argument and
    evidence. At the hearing, the parties’ disputes included whether the
    Moriaritys’ dam fell within the DNR’s jurisdiction to regulate dams built
    in, on, or along streams and, if so, whether the dam was properly
    classified as a high-hazard dam. After the hearing, the presiding
    administrative law judge issued her Findings of Fact, Conclusions of Law
    and Nonfinal Order generally in favor of the DNR.
    The Moriaritys objected to the administrative law judge’s order, and
    the Natural Resources Commission (the “NRC”) held oral argument. The
    NRC then issued its Findings of Fact, Conclusions of Law and Final Order
    (the “Final Order”) largely along the same lines as the administrative law
    judge’s nonfinal order.1 The NRC found that the DNR’s use of the
    common meaning of the word stream was proper and constituted an
    ascertainable standard for identifying a stream, that the Moriaritys’ dam
    was in, on, or along at least one stream, and that there was sufficient
    evidence to support the conclusion that the Moriaritys’ dam was a high-
    hazard dam. The NRC ordered the Moriaritys to address the issues with
    their dam, giving them essentially two options: (1) have a professional
    engineer help safely lower the water in the pond, inspect the dam, make
    any necessary repairs to the dam, and refill the pond, or (2) have a
    professional engineer help “dewater, breach and permanently
    decommission the dam.” See Appellants’ Corrected App. Vol. 2, pp. 56–
    57, ¶¶ 1–5. The NRC also ordered the Moriaritys to pay civil penalties
    1In this context, the NRC is the ultimate authority of the DNR. Ind. Code § 14-10-2-3 (2014
    Repl.). Thus, the Final Order represented the DNR’s last order on the matter.
    Indiana Supreme Court | Case No. 18S-PL-00296 | January 3, 2019                    Page 3 of 17
    totaling $10,000 for past violations of the Dam Safety Act without
    imposing daily penalties for continuing violations. 
    Id. at 57,
    ¶ 6.
    The Moriaritys sought judicial review of the Final Order, and the trial
    court affirmed. It ordered the Moriaritys to take the specific action
    ordered by the DNR, quoting some paragraphs from the NRC’s final
    order and summarizing others. The Moriaritys filed a motion to correct
    error, which was later deemed denied.
    The Moriaritys then appealed to the Court of Appeals. Moriarity v. Ind.
    Dep’t of Nat. Res., 
    91 N.E.3d 642
    (Ind. Ct. App. 2018). They raised many of
    the same issues as before the NRC and trial court, and the Court of
    Appeals affirmed. 
    Id. at 646–49.
    They also challenged the Final Order to
    the extent that it did not expressly allow them to modify their pond and
    dam so that it would fall outside DNR’s jurisdiction, but the Court of
    Appeals found this argument waived. 
    Id. at 649.
    We granted the Moriaritys’ petition to transfer, thereby vacating the
    Court of Appeals opinion. See Ind. Appellate Rule 58(A).
    Standard of Review
    The Moriaritys challenge the trial court’s order upholding the DNR’s
    administrative decision. Under Indiana’s Administrative Orders and
    Procedures Act (“AOPA”), we may set aside an agency’s action if it is:
    (1) arbitrary, capricious, an abuse of discretion, or otherwise
    not in accordance with law; (2) contrary to constitutional
    right, power, privilege, or immunity; (3) in excess of statutory
    jurisdiction, authority, or limitations, or short of statutory
    right; (4) without observance of procedure required by law;
    or (5) unsupported by substantial evidence.
    Ind. Code § 4-21.5-5-14(d) (2018). The Moriaritys bear the burden of
    showing us that the DNR’s action is invalid. I.C. § 4-21.5-5-14(a).
    With AOPA in mind, we note that “[o]ur review of agency action is
    intentionally limited, as we recognize an agency has expertise in its field
    and the public relies on its authority to govern in that area.” Ind. Alcohol

    findings if they are supported by substantial evidence.” 
    Id. “On the
    other
    hand, an agency’s conclusions of law are ordinarily reviewed de novo.”
    
    Id. While “[w]e
    are not bound by the [agency’s] conclusions of law, . . .
    ‘[a]n interpretation of a statute by an administrative agency charged with
    the duty of enforcing the statute is entitled to great weight, unless this
    interpretation would be inconsistent with the statute itself.’” Chrysler

    960 N.E.2d 118
    , 123
    (Ind. 2012) (third alteration in original) (quoting LTV Steel Co. v. Griffin,
    
    730 N.E.2d 1251
    , 1257 (Ind. 2000)). See also Nat. Res. Comm’n v. Porter Cty.
    Drainage Bd., 
    576 N.E.2d 587
    , 588 (Ind. 1991) (stating that “the
    interpretation of a statute by the administrative agency charged with its
    enforcement is entitled to great weight”). “In fact, ‘if the agency’s
    interpretation is reasonable, we stop our analysis and need not move
    forward with any other proposed interpretation.’” Jay Classroom Teachers
    Ass’n v. Jay Sch. Corp., 
    55 N.E.3d 813
    , 816 (Ind. 2016) (citation omitted).
    Like many cases involving judicial review of agency action, the outcome
    here turns on this standard of review.
    Despite the dissent’s resolute arguments to the contrary, applying this
    standard of review comports with precedent and our prior decision in
    NIPSCO Industrial Group v. Northern Indiana Public Service Co., 
    100 N.E.3d 234
    , 241 (Ind. 2018). Rather than effecting a sea change in NIPSCO, we
    applied a specific, controlling portion of the same standard we recite
    today. Both in NIPSCO and here, we note that we ordinarily review legal
    questions addressed by an agency de novo. 
    Id. In NIPSCO,
    that was our
    primary focus. 
    Id. We did
    not continue our discussion of the standard of
    review to address an agency’s interpretation of the relevant statute
    because there was no need; we found the agency’s interpretation contrary
    to the statute itself and, thus, necessarily unreasonable. Compare 
    id. at 237–38,
    242, with Jay Classroom Teachers 
    Ass’n, 55 N.E.3d at 816
    (instructing
    that we accept an agency’s interpretation only if it is reasonable), and
    Chrysler Grp., 
    LLC, 960 N.E.2d at 123
    (providing that an agency’s
    interpretation that is inconsistent with the statute itself does not receive
    Indiana Supreme Court | Case No. 18S-PL-00296 | January 3, 2019      Page 5 of 17
    “great weight”). Here, on the other hand, we continue our discussion and
    recite the full standard because in Part I.A. below we find the DNR’s
    interpretation reasonable and not inconsistent with the Dam Safety Act.
    Differences in the respective agencies’ statutory interpretations in NIPSCO
    and here lead us to focus on different parts of the standard of review. In
    both cases, however, the whole standard remains the same.
    Taking a step back from the details of these cases, this standard of
    review does not abdicate any of our duties, diminish the role of the
    judiciary, or cast doubt on any rules of statutory construction by
    implication. This standard entails a fresh look at the dispute on appeal,
    including the agency’s interpretation of the relevant statute, and allows us
    to continue to say what the law is. It retains for the judiciary the ultimate
    power to determine the outcome of the dispute based on the law and facts,
    but it also recognizes the expertise contained within a co-equal branch of
    government and the value to the public in being able to rely on reasonable
    agency interpretations. Finally, as was the case in each prior opinion to
    apply this standard, our use of the standard here does nothing to cast
    doubt on the continued vitality of the rule of lenity.
    Discussion and Decision
    The Dam Safety Act, in relevant part, is concerned with the safety of
    certain dams2 in, on, or along streams in Indiana. I.C. § 14-27-7.5-8(a)(1)
    (2004). It places an affirmative obligation on the owners of such dams to
    properly maintain them, I.C. § 14-27-7.5-7(a), and it gives the DNR
    supervisory and enforcement power to ensure this happens, I.C. § 14-27-
    7.5-8(a)(1)–(2). Here, the DNR asserted jurisdiction over the Moriaritys’
    dam after concluding it was in, on, or along a stream, it then assigned a
    hazard classification to the dam based on the assessed risk to nearby
    people and property, and it finally ordered the Moriaritys to perform
    2The Act speaks in terms of structures, which are defined as dams and their “appurtenant
    works.” I.C. § 14-27-7.5-5 (2004). For ease of discussion, references in this opinion to a dam
    are meant to include its appurtenant works.
    Indiana Supreme Court | Case No. 18S-PL-00296 | January 3, 2019                      Page 6 of 17
    certain inspection and maintenance activities. The Moriaritys challenge
    the DNR’s jurisdiction, its hazard classification, and its ordered actions.
    We address each argument in turn.
    I.     The DNR has jurisdiction over the Moriaritys’
    dam based on its location in, on, or along a stream
    of Indiana.
    The Dam Safety Act gives the DNR jurisdiction over dams “in, on, or
    along the rivers, streams, and lakes of Indiana.” I.C. § 14-27-7.5-8(a)(1).
    The DNR’s assertion of jurisdiction over the Moriaritys’ dam rested
    primarily on the presence of at least one stream on the property, and so
    the Moriaritys focus their jurisdictional arguments on the word stream.
    They argue that the DNR improperly defined the word and that it failed
    to provide an ascertainable standard of what constitutes a stream.3 Both
    arguments fail.
    A. The DNR’s definition of stream was reasonable.
    Neither the legislature nor the DNR have defined the word stream for
    purposes of the Dam Safety Act, and the Moriaritys argue that the DNR
    used an improper definition here. When presented with a question of
    statutory interpretation, “our primary goal is to ascertain the legislature’s
    intent[,] . . . look[ing] first to the statutory language itself.” Suggs v. State,
    
    51 N.E.3d 1190
    , 1193 (Ind. 2016). If the legislature has not defined a word,
    we give the word its plain, ordinary, and usual meaning, consulting
    3 To the extent the Moriaritys challenge the factual basis for the finding that their dam was
    located in, on, or along a stream, their argument fails. The DNR presented substantial
    evidence, by way of testimony of at least six witnesses along with photographs, to support its
    finding that the dam was built in, on, or along a stream. See Appellants’ Corrected App. Vol.
    2, p. 88 (testimony of Robert Wilkinson); Appellee’s App. Vol. II, pp. 85–86, 91–92, 95–107
    (testimony of Kenneth Smith referencing photographs); 
    id. at 222–25
    (testimony of Rodney
    Neese); Appellee’s App. Vol. III, pp. 28–31 (testimony of Jon Eggen); 
    id. at 95–96
    (testimony of
    Darrin Miller); 
    id. at 169–70
    (testimony of George Crosby).

    English language dictionaries when helpful in determining that meaning.
    State v. Hancock, 
    65 N.E.3d 585
    , 587 (Ind. 2016). But when, as happened
    here, an agency interprets a statute it is tasked with enforcing, we give the
    agency’s interpretation “great weight” and stop our analysis if that
    interpretation is reasonable. 
    West, 54 N.E.3d at 353
    (citation omitted).
    Here, the DNR identified a stream as “flowing water through a defined
    channel” with neither size nor consistency of water flow being
    determinative of the presence of a stream. Appellants’ Corrected App.
    Vol. 2, pp. 51–52. This definition is consistent with dictionary definitions
    of the word. See Stream, WEBSTER’S THIRD NEW INTERNATIONAL
    DICTIONARY 2259 (2002) (defining the word as “a body of running water
    flowing in a channel on the surface of the ground . . .”). See also Appellee’s
    App. Vol. V, pp. 6–10 (providing various definitions of the word). And
    there is no indication that this definition is inconsistent with the Dam
    Safety Act itself. Because the definition the DNR used is consistent with
    the plain, ordinary, and usual meaning of the word stream, it is
    reasonable, and we “need not move forward with any other proposed
    interpretation.” Jay Classroom Teachers 
    Ass’n, 55 N.E.3d at 816
    (citation
    omitted).
    B. The Moriaritys had adequate notice of what constitutes
    a stream for purposes of the Dam Safety Act.
    The Moriaritys contend that they lacked adequate notice that their
    property contained a stream that could bring their dam within the DNR’s
    Dam Safety Act jurisdiction. Specifically, they claim that the “DNR, by
    failing to promulgate any regulations or guidance [defining stream under
    the Act] and relying solely on the statute, had not given any notice or fair
    warning” that their dam would fall within DNR’s jurisdiction. Pet. to
    Transfer, pp. 7–8. As the Moriaritys correctly point out, “[a]dministrative
    decisions must . . . be based on ascertainable standards in order to be fair
    and consistent rather than arbitrary and capricious.” State Bd. of Tax
    Comm’rs v. New Castle Lodge #147, Loyal Order of Moose, Inc., 
    765 N.E.2d 1257
    , 1264 (Ind. 2002). These standards “give fair warning as to what the
    agency will consider in making its decision.” 
    Id. (citation omitted).
    Indiana Supreme Court | Case No. 18S-PL-00296 | January 3, 2019     Page 8 of 17
    However, this ascertainable standards requirement is not meant to unduly
    constrain administrative action because agencies are “entitled to
    reasonable latitude in carrying out [their] responsibilities.” 
    Id. at 1264
    n.13
    (citing State Bd. of Tax Comm’rs v. Garcia, 
    766 N.E.2d 341
    (Ind. 2002)). The
    Moriaritys fail to show that the DNR’s reliance on the language of the Act,
    rather than on explanatory regulations or other guidance, failed to
    provide an ascertainable standard for two reasons.
    As an initial matter, an agency is not required to promulgate
    regulations defining each word in a statute. Although the Moriaritys
    seem to advocate for this rule, they cite no law foisting such a burden
    upon agencies in Indiana. To the contrary, we have a well-established
    rule to deal with these situations: “[u]ndefined words . . . are given their
    plain, ordinary and usual meaning.” 
    Hancock, 65 N.E.3d at 587
    (citing I.C.
    § 1-1-4-1(1) (2016 Repl.)). Here, the DNR based its definition of the word
    stream on the standard dictionary definition, as the legislature and this
    Court have instructed. This reasonable definition gave the Moriaritys fair
    warning as to what the DNR would consider a stream. It was neither
    arbitrary nor capricious.
    Additionally, the Moriaritys’ intense focus on the word stream and the
    lack of regulations defining the word loses sight of the legislature’s intent
    in enacting the Dam Safety Act and the Act’s other jurisdictional
    provisions. As the colloquial name of the Act implies, it is all about the
    safety of dams. See, e.g., I.C. § 14-27-7.5-7(a) (2004). It is not a law
    regulating streams. While the word stream is one part of the Act’s
    jurisdictional grant, see I.C. § 14-27-7.5-8(a)(1), it cannot be viewed in
    isolation without also considering the broader context of the statutory
    provision within the Dam Safety Act. In fact, another provision provides
    specific guidance on dams that fall outside the Act. I.C. § 14-27-7.5-1.
    Dams that are no more than twenty feet high and that do “not impound a
    volume of more than one hundred . . . acre-feet of water[,]” among other
    things, are not within the DNR’s Dam Safety Act jurisdiction. I.C. § 14-27-
    7.5-1(1). When the word stream is viewed in light of the Act’s purpose
    and the other jurisdictional provisions, individuals have more than fair
    notice of which dams might fall within the DNR’s jurisdiction. This
    conclusion is driven home even more forcefully in this case, where the
    Indiana Supreme Court | Case No. 18S-PL-00296 | January 3, 2019      Page 9 of 17
    Moriaritys stipulated that parts of their dam were taller than twenty feet
    and that their dam impounded more than one hundred acre-feet of water.
    Appellee’s App. Vol. II, pp. 48–49. The Moriaritys have failed to show
    that the DNR’s exercise of jurisdiction over their dam based on the
    statutory language of the Dam Safety Act was arbitrary or capricious.
    II. The DNR presented substantial evidence
    supporting its classification of the Moriaritys’
    dam as a high-hazard dam.
    As part of its supervisory duties under the Dam Safety Act, the DNR
    must assign a hazard classification—high, significant, or low—to each
    dam within its jurisdiction based on the risk posed to life and property in
    the event of an uncontrolled release from the dam. I.C. § 14-27-7.5-8(b).
    The DNR classified the Moriaritys’ dam as high-hazard, and the
    Moriaritys argue on appeal that this classification lacks substantial
    evidence. While the Moriaritys acknowledge that two DNR witnesses
    testified that the dam was a high-hazard structure, they argue that an
    inundation study the DNR completed was so flawed that the DNR’s
    conclusion on the dam’s hazard classification was not supported by
    substantial evidence.
    When reviewing a claim that an agency’s decision lacks substantial
    evidence, “the reviewing court may vacate [the] decision only if the
    evidence, when viewed as a whole, demonstrates that the conclusions
    reached by the [agency] are clearly erroneous.” Regester v. Ind. State Bd. of
    Nursing, 
    703 N.E.2d 147
    , 151 (Ind. 1998) (citation omitted). “A judgment is
    clearly erroneous when there is no evidence supporting the findings or the
    findings fail to support the judgment.” E.B.F. v. D.F., 
    93 N.E.3d 759
    , 762
    (Ind. 2018).
    The Dam Safety Act defines a high-hazard dam as “[a] structure the
    failure of which may cause the loss of life and serious damage to homes,
    industrial and commercial buildings, public utilities, major highways, or
    Indiana Supreme Court | Case No. 18S-PL-00296 | January 3, 2019   Page 10 of 17
    railroads.” I.C. 14-27-7.5-8(b)(1).4 The Act’s regulations instruct the
    DNR’s Division of Water to assign its hazard classifications “based on
    [the] best information available” and expressly allow it to “consider
    observations of the dam and the vicinity of the dam, including the risk
    posed to human life and property if the dam fails.” 312 Ind. Admin. Code
    10.5-3-1(a), (c) (2012),
    http://www.in.gov/legislative/iac/T03120/A00105.PDF?&iacv=iac2012. To
    support its high-hazard assessment, the DNR presented testimony of two
    of its employees as well as an inundation study conducted on the dam.
    On the other hand, the Moriaritys presented testimony casting doubt on
    the accuracy of the inundation study. Even ignoring the evidence from
    the inundation study, the DNR presented substantial evidence supporting
    the dam’s high-hazard classification. Kenneth Smith, the Assistant
    Director of DNR’s Division of Water, testified that the presence of a
    church, a home, and a road below the dam made it “visually obvious” that
    it would likely be a high-hazard dam. Appellants’ Corrected App. Vol. 2,
    pp. 128–29. George Crosby, the Manager of DNR’s Dam Safety Section,
    testified that, if the dam broke above the house situated below the dam, it
    would cause “serious damage.” Appellants’ Corrected App. Vol. 3, p. 45.
    He also testified that the dam would be classified as high-hazard even
    without the homes below because the road below the dam was heavily
    trafficked. Appellee’s App. Vol. III, p. 187–88. Thus, substantial evidence
    supports the DNR’s conclusion that the Moriaritys’ dam was a high-
    hazard structure. The Moriaritys’ argument to the contrary fails.
    4We note that the standards for classifying a dam as high-hazard are not the same in the

    damage to property). The parties do not ask us to resolve this apparent inconsistency.

    III. The Moriaritys may, in the course of complying
    with the trial court’s order, modify their dam to
    remove it from DNR’s jurisdiction.
    The Moriaritys insist that the DNR exceeded its jurisdiction by issuing
    its Final Order that did not expressly allow them to modify their dam to
    remove it from the DNR’s jurisdiction. They seek a modification of the
    trial court’s order enforcing the Final Order to include an express
    provision allowing them to change their dam so that it no longer falls
    within the DNR’s Dam Safety Act jurisdiction, or they ask us to remand
    with instructions that they may change their dam to remove it from the
    DNR’s jurisdiction. Regardless of any potential waiver of this argument
    due to the Moriaritys’ failure to raise it before their motion to correct
    error, we will address it. See Pierce v. State, 
    29 N.E.3d 1258
    , 1267 (Ind.
    2015) (citation omitted) (“[W]henever possible, ‘we prefer to resolve cases
    on the merits’ instead of on procedural grounds like waiver.”).
    The trial court’s order largely adopted the portions of the DNR’s Final
    Order regarding compliance with the Dam Safety Act going forward.
    Appellants’ Corrected App. Vol. 2, pp. 25–26. Modification of this order is
    not necessary, but the Moriaritys may choose to modify their dam in the
    course of complying with the trial court’s order in order to remove it from
    the DNR’s jurisdiction from that point forward. As noted above, the
    Moriaritys stipulated that their dam exceeded twenty feet in height and
    impounded a volume of more than one hundred acre-feet of water, both
    of which meant their dam did not qualify for the Dam Safety Act’s
    statutory exception. See I.C. § 14-27-7.5-1(1) (2004). If they modify it so
    that it no longer exceeds a height of twenty feet or impounds more than
    one hundred acre-feet of water (along with the other statutory
    requirements), the DNR will no longer have jurisdiction over the dam
    under the Dam Safety Act.5 The DNR acknowledged that this option was
    5Since the trial court’s order affirming the Final Order contemplated actions taken under the
    supervision or direction of a professional engineer, any modification would necessarily also
    involve a professional engineer’s oversight.

    available to the Moriaritys, Oral Argument at 20:58–22:50, and the
    Moriaritys acknowledged that they would accept this option, 
    id. at 17:05–
    17:20, 18:19–18:58. Whether the parties ultimately act on this apparent
    agreement is up to them.6
    Conclusion
    For the reasons stated herein, we affirm the trial court’s order enforcing
    the Final Order. We find, however, that the Moriaritys can, in the course
    of complying with the trial court’s order, modify their dam to remove it
    from the DNR’s jurisdiction under the Dam Safety Act. Given the parties’
    unsuccessful attempts at settlement despite their apparent agreement in
    principle, we anticipate disagreements may arise if the Moriaritys choose
    to modify their dam to remove it from the DNR’s jurisdiction. Because
    those disagreements have only been hinted at and not fully litigated to
    date, we cannot offer guidance on them but instead leave that to the trial
    court, should the need arise. See State ex rel. Brubaker v. Pritchard, 
    236 Ind. 222
    , 226, 
    138 N.E.2d 233
    , 235 (Ind. 1956) (“It is well established that once a
    court acquires jurisdiction over parties, the jurisdiction continues until the
    final disposition of the litigation including the enforcement of the
    judgment or decree.”). Therefore, we remand to the trial court for further
    proceedings consistent with this decision.
    6 With the appeal before us resolved, we pause now to comment on a broader issue implicated
    by this dispute. Although the DNR has largely won here, it likely could have avoided this
    protracted litigation in the first place by defining the word stream for purposes of the Dam
    Safety Act. It clearly knows how to define words for the Act, see 312 Ind. Admin. Code 1-1-
    21(a) (2018), http://www.in.gov/legislative/iac/T03120/A00010.PDF?&iacv=iac2018 (defining
    lake), and, as this case demonstrates, DNR employees have a shared understanding of the
    word stream. Defining the word would presumably reduce the complexity of enforcement
    actions and increase public confidence in the agency’s decisions.

    Slaughter, J., dissenting.
    I respectfully dissent from the Court’s decision for two reasons. First,
    on the standard of review, I would give no deference to the Department’s
    interpretation of “stream” within the Dam Safety Act. The prerogative to
    interpret the law authoritatively belongs to us. And we disserve
    separation-of-powers principles when we allow agencies within the
    executive branch to usurp a core judicial function. Second, on the merits,
    the Court’s conclusion that the Department properly exercised jurisdiction
    over the Moriaritys’ property follows from the Court’s deferential
    standard of review. Its application of the wrong standard has caused it to
    reach the wrong result.
    I’ll begin with the standard of review. Just this year, we held
    unanimously that we review agencies’ legal determinations “de novo”;
    that we accord such determinations “no deference”; that plenary review of
    agency decisions is “constitutionally preserved” for the judiciary; that our
    separation-of-powers doctrine does not contemplate a “tie-goes-to-the-
    agency” standard for reviewing agency decisions on questions of law; and
    that we decide the statutory interpretation that is “best” and “do not
    acquiesce in the interpretations of others.” NIPSCO Indus. Grp. v. Northern
    Indiana Pub. Serv. Co., 
    100 N.E.3d 234
    , 241 (Ind. 2018).
    In contrast, the Court today applies a very different standard. It opens
    by describing the standard as “de novo” but then says the interpretation
    of a statute by the agency charged with enforcing it is entitled to “great
    weight”; and that an agency’s interpretation need only be “reasonable”, at
    which point we will “stop our analysis” and not consider “any other
    proposed interpretation.”
    I had thought this discredited standard, which the Court resurrects
    today, had been laid to rest for good in NIPSCO. What we held in NIPSCO
    cannot be reconciled with the standard the Court applies today. It is no
    answer that NIPSCO involved the Utility Regulatory Commission and
    today’s decision concerns the Department of Natural Resources. There is
    no principled reason, consistent with separation of powers, for according
    fundamentally different treatment to the statutory interpretations of
    different agencies within the executive branch of state government. An
    Indiana Supreme Court | Case No. 18S-PL-00296 | January 3, 2019   Page 15 of 17
    agency interpretation that is “reasonable” but not the “best” is not good
    enough. Allowing an agency’s reasonable interpretation to prevail over
    our best interpretation ignores our unique “law-giving function”, A.A. v.
    Eskenazi Health/Midtown CHMC, 
    97 N.E.3d 606
    , 610 n.1 (Ind. 2018), which
    includes our inherent constitutional “duty to act as the final and ultimate
    authority” in pronouncing Indiana law, 
    id. (quoting Troue
    v. Marker, 
    253 Ind. 284
    , 288, 
    252 N.E.2d 800
    , 803 (1969)).
    These rival standards of review—“only the best” vs. “reasonable will
    do”—are not only irreconcilable but proceed from very different visions of
    the role of the judiciary within our constitutional scheme. NIPSCO regards
    the judiciary as a vital, co-equal branch within our tripartite system of
    government with ultimate responsibility for interpreting the law. Today’s
    decision, however, treats the judiciary as a bit player with a limited role
    vis-à-vis the other two branches. To be sure, judicial modesty has its place.
    But we should not confuse modesty with abdication. Our job is to
    interpret the law fully and faithfully—no more, no less. Today’s standard
    does much less. It is a standard where judicial review is plenary in theory,
    deferential in name, and a rubberstamp in fact.
    We do not give similar deference to other actors who wield executive
    power. For example, we afford zero deference to prosecuting attorneys,
    who exercise an essential aspect of the State’s executive power: the power
    “to enforce the criminal laws of the State of Indiana”. State ex rel. Egan v.
    Superior Ct. of Lake Cty., 
    211 Ind. 303
    , 309, 
    6 N.E.2d 945
    , 947 (1937).
    Prosecutors would seemingly have greater standing to insist on deference
    when interpreting the laws they enforce. Unlike executive-branch
    agencies, prosecutors are not creatures of statute but constitutional
    officers. Ind. Const. art. 7, § 16. As between them, one might think that if
    deference were ever appropriate on matters of legal interpretation, it
    would be constitutional officers who deserve the benefit of the doubt. But
    our caselaw holds otherwise. If a criminal statute is ambiguous, we do not
    give “great weight” to a prosecutor’s interpretation or require that the
    interpretation only be “reasonable” to withstand legal challenge. To the
    contrary, our rule of lenity holds that ambiguity in a statute defining a
    crime should be resolved in favor of the defendant. Day v. State, 
    57 N.E.3d 809
    , 813 (Ind. 2016). Make no mistake—that is how it should be. But given
    Indiana Supreme Court | Case No. 18S-PL-00296 | January 3, 2019    Page 16 of 17
    the standard of review the Court applies today, one might fairly ask
    whether the rule of lenity’s continued validity is now in doubt. I hope the
    answer is no, but I am not confident of that. At a minimum, today’s
    standard erodes the rule’s doctrinal underpinnings.
    Turning to the merits, the conclusion that the Department properly
    exercised jurisdiction under the Dam Safety Act is premised on the
    Court’s acquiescence in the Department’s determination that the disputed
    dam was located along a “stream”. As the Court acknowledges, its lax
    standard of review ensured the Department’s jurisdictional ruling would
    be upheld: “Like many cases involving judicial review of agency action,
    the outcome here turns on this standard of review.” On this point, I agree
    with the Court. A more robust standard would have led to a different
    outcome on the threshold question of the Department’s exercise of
    jurisdiction over the Moriaritys’ property. Because the Court applied the
    wrong standard, it reached the wrong result.
    I respectfully dissent.
