    JUSTICE PETERSEN, opinion of the Court:
    INTRODUCTION
    ¶1 Roger B. and Kimberly L. Arave, Janet Southwick, and
    the owners of the Snowberry Inn bed-and-breakfast (collectively,
    Plaintiffs) each have decades-old water rights that allow them to
    meet their own water needs. They divert their water through the
    use of two wells. Pineview West Water Company has a much
    larger, junior water right that allows it to supply water to seventy
    single-family homes and irrigate over twenty acres of land.
    ARAVE V. PINEVIEW
    Opinion of the Court
    Pineview operates five wells that are much deeper and stronger
    than those of the Plaintiffs. The Plaintiffs claim that Pineview has
    interfered with their water rights because when one of Pineview’s
    wells operates (Well 4), it lowers the water table and puts the
    available water beyond the reach of their pumps. After a bench
    trial, the district court found in favor of the Plaintiffs on their
    claims of interference and negligence.
    ¶2 Pineview appeals, raising the following issues. With
    regard to the Plaintiffs’ interference claims, Pineview asserts the
    Plaintiffs did not establish interference because they did not prove
    that they were unable to obtain some amount of their respective
    water rights and that their means and methods of diversion were
    reasonable. Pineview asserts that the Plaintiffs’ negligence claim
    should fail because they did not bring it against the proper
    parties. And finally, Pineview argues that even if the Plaintiffs
    properly prevailed on their interference and negligence claims,
    the district court incorrectly calculated damages.
    ¶3 We reverse the district court’s determination that
    Pineview interfered with the Plaintiffs’ wells. We do not disturb
    the court’s ruling on negligence. However, we remand that claim
    to permit the district court to consider whether it survives the
    dismissal of the Plaintiffs’ interference claims and to make
    additional findings, if necessary. We vacate a portion of the
    Plaintiffs’ damages award. And we remand the district court’s
    calculation of the remaining damages and imposition of forward-
    looking remedies for the court to determine if and how they are
    impacted by the dismissal of the Plaintiffs’ interference claims.
    BACKGROUND1
    The Parties
    ¶4 Roger B. and Kimberly L. Arave are joint owners and
    residents of a single-family residential property. They own a
    water right with a priority date of 1963. The Araves’ water right
    allows them to divert 0.45 acre-feet2 of water annually at a flow

    2The acre-foot is “the standard unit of measurement of the
    volume of water,” which is “the amount of water upon an acre

    rate of 6.7 gallons per minute to supply water for single-family
    domestic use3 and two livestock units.
    ¶5 Janet Southwick, as trustee, is the sole owner and resident
    of a single-family residential property. She owns a water right
    with a priority date of 1978. Southwick’s water right allows her to
    divert one acre-foot of water annually to irrigate 0.25 acres of land
    and supply water for single-family domestic use.
    ¶6 The Araves and Southwick share the Arave Well as the
    sole diversion point for their year-round water rights. The Arave
    Well was drilled in 1963 to a depth of 187 feet with perforations
    from 140 to 170 feet. The perforations are entirely in an aquifer
    called the Norwood Tuff.4
    ¶7 Venture Development Group, a limited liability
    company, is the sole owner of a residential property that operates
    a commercial bed-and-breakfast known as the Snowberry Inn. It
    includes nine bedrooms, nine bathrooms, two kitchens, and serves
    as the year-round residence of the Inn’s operator. Venture owns
    two water rights with priority dates of 1960 and 2017. Venture’s
    original water right allows it to divert 0.45 acre-feet of water
    annually at a flow rate of 6.7 gallons per minute to supply water
    for single-family domestic use. However, Venture had been using
    more water than it had lawfully appropriated, and it was using
    the water in ways that were not permitted under its original water
    right. So in 2017, it applied to appropriate additional water. Its
    new water right, acquired pursuant to a change application,
    covered one foot deep, equivalent to 43,560 cubic feet.” UTAH
    CODE § 73-1-2.
    3 One domestic unit permits a water right holder to divert 0.45
    acre-feet of water to meet the indoor supply needs of five people.
    4  There are two local aquifers relevant to this case: the
    Norwood Tuff and an area of unconsolidated material that lies on
    top of it. While the Norwood Tuff is a consolidated bedrock
    aquifer, the unconsolidated material consists predominantly of
    sand, gravel, and cobble. The unconsolidated material generally
    has greater permeability than the Norwood Tuff, meaning that
    fluid is able to pass through it more easily. But the area of the
    Norwood Tuff surrounding the three wells is likely fractured,
    which increases its permeability. The intensity and extent of the
    fracturing are unknown.
    3
    ARAVE V. PINEVIEW
    Opinion of the Court
    allows Venture to divert an additional 3.25 acre-feet of water for
    irrigation and commercial use at the Snowberry Inn.
    ¶8 Venture diverts water year-round from the Snowberry
    Well, which was drilled in 2001 to a depth of 133 feet. Its
    perforations are from 105 to 125 feet and span both the Norwood
    Tuff and the unconsolidated material on top of it. The well likely
    gets the majority of its water from the more permeable
    unconsolidated material, but it is hydrologically connected to the
    Norwood Tuff. The Snowberry Well is equipped with a pump
    that has the capacity to pump twenty-five gallons per minute. The
    pump transfers water into a cistern, which then pumps water into
    the Snowberry Inn. The cistern is equipped with sensors that turn
    the pump on when the water level inside the cistern drops below
    a certain point and then signal the pump to turn off when the
    cistern is full.
    ¶9 While the Plaintiffs use their water rights to meet their
    own domestic and business needs, Pineview is a small water
    company that owns and operates five wells, including the one at
    issue here—Well 4. Pineview’s water rights are almost thirty-three
    times larger than the Plaintiffs’ rights combined,5 and it supplies
    water to seventy single-family homes and irrigates over twenty
    acres of land. But its rights are junior to all of the Plaintiffs’ rights
    except the latest one that Venture acquired. Its earliest right,
    modified by a change application, has a 2003 priority date. The
    state engineer’s approval stated that modification was “subject to
    prior rights.” In 2013, the state engineer approved a new change
    application, allowing Pineview to divert additional water.
    Pineview may divert its water from any combination of the five
    wells.
    ¶10 Well 4 is located approximately 700 feet from the Arave
    Well and approximately 460 feet from the Snowberry Well. It was
    drilled in 2004 to a depth of 738 feet with four perforated zones
    from 58 to 98 feet, 208 to 228 feet, 408 to 448 feet, and 648 to 738
    feet. Well 4 draws water from both aquifers, but most of its water
    __________________________________________________________
    5  Pineview’s 2003 water right allows it to divert 90 acre-feet of
    water annually to irrigate 21.66 acres of land and supply water to
    fifty-five single-family domestic units. Its 2013 water right allows
    it to appropriate an additional 78 acre-feet of water annually.
    4
    Cite as: 
    2020 UT 67
    Opinion of the Court
    likely comes from the Norwood Tuff. Well 4 is equipped with a
    pump that has the capacity to pump 100 gallons per minute.
    The Dispute
    ¶11 When Well 4 was tested for the first time in 2004, it
    affected the Arave Well almost immediately. Within hours, the
    Arave Well was unable to pump any water and began sucking air,
    resulting in silt damage to the Araves’ and Southwick’s property.
    So the test was cut short. The Arave Well recovered within a day
    or two following that initial test. But a subsequent test produced
    the same result.
    ¶12 Nevertheless, Pineview later began regularly pumping
    Well 4 during irrigation season, from early July until September.
    When Well 4 was operating, the Arave Well was once again
    unable to produce water. Eventually, the Snowberry Well had
    trouble as well. It had traditionally been able to fill its cistern
    within fifteen minutes. But with Well 4 operating, the Snowberry
    Well struggled for hours to complete the same task.
    ¶13 In the beginning, the parties resolved this problem
    amongst themselves. Pineview agreed to connect the Plaintiffs to
    its water supply and provide them with culinary water for a flat
    rate of $20 per month. Once the Araves and Southwick began
    using Pineview’s water, the Araves removed the pump from the
    Arave Well and no longer used it to obtain water. Instead, they
    used it as a monitoring well to gather data regarding the impact of
    Well 4 on the water level.
    ¶14 Several years later, Pineview sought to increase the
    Plaintiffs’ fees to match those paid by its other water users. The
    parties tried to reach an agreement regarding new fees, but those
    negotiations broke down and this suit followed.
    ¶15 The Plaintiffs sued Pineview, asserting causes of action
    for interference with water rights, negligence, and nuisance.6 In
    their complaint, they sought injunctive relief, damages, and
    attorney fees.
    __________________________________________________________
    6During the final day of trial, the district court asked whether
    nuisance was actually a claim in this case. Although the Plaintiffs
    argued that it was, the court’s findings of fact and conclusions of
    law do not address this claim. And it is not before us on appeal.
    5
    ARAVE V. PINEVIEW
    Opinion of the Court
    The Final Amended Judgment
    ¶16 Following a four-day bench trial during which the district
    court heard expert testimony from both sides, the court ruled in
    favor of the Plaintiffs on their interference and negligence claims.
    In support of the verdict, the district court entered findings of fact
    and conclusions of law.
    ¶17 The district court found that neither the Arave Well nor
    the Snowberry Well had ever experienced difficulty diverting
    water before Well 4 began pumping. But when Well 4 was in
    operation, the court found that it created a cone of depression that
    encompassed both the Arave and Snowberry Wells. The district
    court explained that a cone of depression is an “underground area
    of reduced soil saturation [that] is in the shape of an inverted
    cone, with the point of the cone extending downward toward the
    point at which the water is extracted. . . . [T]he depth of the water
    table will be most significantly impacted at the point of extraction
    . . . .” (Quoting Bingham v. Roosevelt City Corp., 
    2010 UT 37
    , ¶ 3, 
    235 P.3d 730
    .) The actual shape of a cone of depression varies
    depending on the nature, depth, and permeability of the
    surrounding aquifer.
    ¶18 The district court noted that the Arave Well is a “very
    good surrogate” for Well 4 because it reacts “quickly and
    accurately” when Well 4 is operating. But the impact on the
    Snowberry Well is more complex. The district court found that the
    Arave Well is hydrologically connected to the Snowberry Well.
    When Well 4 operates, it immediately draws down the water level
    of the Arave Well. When the elevation of the Arave Well head
    falls below that of the Snowberry Well, water is drawn away from
    the Snowberry Well. As a result, the Snowberry Well “struggles to
    produce even a minimal yield.” Recovery time for both wells
    varies based on several factors.
    ¶19 The district court concluded that Pineview was liable for
    interference with the Plaintiffs’ water rights and negligence. The
    court acknowledged that an aquifer’s water level is influenced by
    various factors, including seasonal fluctuations and the amount of
    water withdrawn by pumping wells. And it found that there had
    not been a general decline in the groundwater levels where the
    wells are located.
    ¶20 But the district court ultimately concluded that pumping
    Well 4 dewatered the aquifer to such a degree that it temporarily
    reduced the level of water available to the Plaintiffs’ wells. In
    particular, when Well 4 was pumping, it deprived the Arave Well
    6
    Cite as: 
    2020 UT 67
    Opinion of the Court
    of “virtually all water” and obstructed the Snowberry Well’s
    ability to produce water. After determining that the Plaintiffs’
    means and methods of diverting water were reasonable, the court
    concluded that Pineview should bear the costs associated with
    rectifying the interference.
    ¶21 The district court also found that before expanding its
    water right in 2017, Venture had used more than its allotted share
    of water, thereby violating the terms and limitations of its original
    water right. But the court rejected Pineview’s argument that this
    should bar Venture’s ability to prevail on an interference claim.
    Instead, the district court noted that the state engineer may
    remedy any such violations by commencing an action under the
    relevant statutory provision.
    ¶22 As to negligence, the district court ruled that Pineview
    was negligent in locating, drilling, and using Well 4 in a manner
    that interfered with the Arave and Snowberry Wells. According to
    the court, harm to the Plaintiffs was foreseeable because Well 4 is
    located near the Plaintiffs’ wells, it draws water from the same
    aquifers that the Plaintiffs use, and it operates at a much larger
    capacity.
    ¶23 As a forward-looking remedy, the district court ordered
    Pineview to stop pumping Well 4 unless and until it could
    demonstrate that Well 4 could operate without interfering with
    the Arave and Snowberry Wells. The court retained jurisdiction to
    determine whether the wells could coexist and to fashion an
    appropriate remedy based on the outcome of that determination.
    In the event that interference proved unavoidable, the district
    court stated that it may order Pineview to provide replacement
    water to the Plaintiffs at Pineview’s sole expense.
    ¶24 The court also awarded compensatory damages. It
    ordered Pineview to refund all of the fees that the Plaintiffs had
    previously paid for water service. It also included the cost of a
    new pump and associated accessories for the Arave Well as well
    as costs that Southwick and Venture had incurred due to hard
    water damage to their property. In sum, the district court
    awarded $11,503 to the Araves; $5,782 to Southwick; and $28,238
    to Venture, along with post-judgment interest at the statutory
    rate. The Plaintiffs, as prevailing parties, were also entitled to
    $2,059.96 in costs.
    ¶25 Pineview appealed. We have jurisdiction pursuant to
    Utah Code section 78A-3-102(3)(j).
    7
    ARAVE V. PINEVIEW
    Opinion of the Court
    STANDARD OF REVIEW
    ¶26 A determination of interference with a water right is a
    mixed question of law and fact. See Wayment v. Howard, 
    2006 UT 56
    , ¶ 9, 
    144 P.3d 1147
    . When reviewing mixed questions, “we
    typically grant some level of deference to the district court’s
    application of law to the facts.” 
    Id.
     The level of deference afforded
    varies based on the issue being reviewed. Searle v. Milburn Irr. Co.,
    
    2006 UT 16
    , ¶ 16, 
    133 P.3d 382
    . Here, “because the issue of
    interference is extremely fact dependent, we grant broad
    deference to the district court.” Wayment, 
    2006 UT 56
    , ¶ 9. The
    same is true of a determination of negligence. “[A] negligence
    finding is a classic finding that, while mixed, calls for deference to
    the lower court.” In re Adoption of Baby B., 
    2012 UT 35
    , ¶ 43, 
    308 P.3d 382
    .
    ANALYSIS
    ¶27 Water has been characterized as the “very life blood” of
    Utah. Fairfield Irr. Co. v. White, 
    416 P.2d 641
    , 644 (Utah 1966).
    Recognizing water’s importance as a vital resource in our arid
    state, Utah statutory and case law have been crafted to maintain
    the flexibility necessary to meet changing circumstances and
    promote optimal beneficial use of our water supply. See 
    id.
     at 644–
    45; see also Wayman v. Murray City Corp., 
    458 P.2d 861
    , 863–65
    (Utah 1969). But our statutory law also protects appropriators of
    water in order of seniority. See UTAH CODE § 73-3-1(5)(a). The
    balance between protecting senior appropriators and maximizing
    the beneficial use of water has led to several rules of water law
    that can sometimes seem to be in tension with one another.
    ¶28 We begin by identifying those rules. We then explain
    how they combine to establish the elements of a prima facie case
    for interference with a water right. Finally, we determine whether
    the district court’s findings sufficiently support its determination
    of interference.
    I. INTERFERENCE
    ¶29 “All waters in this state, whether above or under the
    ground, are . . . the property of the public, subject to all existing
    rights to the use thereof.” UTAH CODE § 73-1-1(1). A person
    seeking to acquire the right to use the state’s unappropriated
    waters must apply for and receive approval from the state
    engineer. See id. § 73-3-2(1)(a).
    ¶30 Appropriators are prioritized according to the dates of
    their respective water rights. See id. § 73-3-21.1(2)(a). In practice,
    8
    Cite as: 
    2020 UT 67
    Opinion of the Court
    this means that except in times of a temporary water shortage
    emergency, “each appropriator is entitled to receive the
    appropriator’s whole supply before any subsequent appropriator
    has any right.” 
    Id.
     § 73-3-21.1(2)(a); see also id. § 73-3-1(5)(a)
    (“Between appropriators, the one first in time is first in rights.”);
    id. § 73-3-8(1)(a)(ii) (stating that the state engineer must consider
    whether the proposed use will impair existing rights when
    approving an application to appropriate). Generally, a cause of
    action for interference lies where a junior appropriator’s use of
    water diminishes the quantity or quality of the senior
    appropriator’s existing water right. Bingham v. Roosevelt City Corp.,
    
    2010 UT 37
    , ¶ 48, 
    235 P.3d 730
    .
    ¶31 If a junior appropriator interferes with a senior
    appropriator’s water right, the junior appropriator has the right—
    at his or her own expense—to replace the senior appropriator’s
    water. Id. ¶ 63; see also Fairfield Irr. Co. v. White, 
    416 P.2d 641
    , 645–
    46 (Utah 1966) (upholding the district court’s order requiring
    defendant to supply replacement water as being supported by the
    evidence). This protection also extends to a senior appropriator’s
    “right to continue use of his [or her] existing and historical
    method of diverting the water.” Wayment v. Howard, 
    2006 UT 56
    ,
    ¶ 13, 
    144 P.3d 1147
    .
    ¶32 When rights clash, however, seniority of rights is not the
    sole consideration. We have previously recognized that ordering a
    junior appropriator to supply replacement water in perpetuity is a
    “sweeping and pervasive responsibility” that “could prove to be
    highly inequitable and inconsistent with the objectives of our
    water law.” Wayman v. Murray City Corp., 
    458 P.2d 861
    , 864 (Utah
    1969). The primary objective is ensuring that “the greatest amount
    of available water is put to beneficial use.” Id. at 865; see also Utah
    Code § 73-1-3 (“Beneficial use shall be the basis, the measure and
    the limit of all rights to the use of water in this state.”). This
    objective becomes an important consideration when a junior
    appropriator’s diversion interferes with a senior appropriator’s
    water right. See Wayman, 458 P.2d at 864–67.
    ¶33 In Wayman, we adopted the “rule of reasonableness,”
    which allows courts to balance competing rights in a manner that
    best achieves the goal of putting the greatest amount of water to
    beneficial use. Id. at 865–67. Under the rule of reasonableness,
    “[a]ll users are required where necessary to employ reasonable
    and efficient means in taking their own waters in relation to
    others to the end that wastage of water is avoided and that the
    9
    ARAVE V. PINEVIEW
    Opinion of the Court
    greatest amount of available water is put to beneficial use.” Id. at
    865. This rule tempers the prior appropriation doctrine, which
    could otherwise allow a senior appropriator to hold
    unappropriated water hostage due to outdated and inefficient
    methods of diversion. Id. at 865–66. In assessing reasonableness,
    courts should consider the total situation, including “the quantity
    of water available, the average annual recharge in the basin, the
    existing rights and their priorities.” Id. at 865.
    ¶34 Protecting senior water rights and maximizing the
    beneficial use of available water both have a place in our law. But
    these concepts do not always easily coexist. We take this
    opportunity to clarify the specific elements of a claim of
    interference with a water right. In doing so, we do not depart
    from prior case law; instead, we seek to synthesize it by
    explaining how the governing concepts should come together to
    establish a prima facie case of interference.
    ¶35 To prevail on an interference claim, we clarify that
    plaintiffs must establish that: (1) they have an enforceable water
    right,7 (2) their water right is senior to the defendant’s water
    right,8 (3) their methods and means of diversion are reasonable,9
    (4) despite their reasonable efforts, they are unable to obtain the
    quantity or quality of water to which they are entitled,10 and
    (5) the defendant’s conduct obstructed or hindered their ability to
    obtain that water (causation).11
    ¶36 The district court found that Pineview interfered with
    both the Arave and Snowberry Wells when it operated Well 4.
    Pineview argues that the district court erred in multiple ways.

    .
    8   See UTAH CODE §§ 73-3-1(5)(a), -21.1(2)(a).
    9 This element is based upon the rule of reasonableness, which

    reasonable and consistent with the state of development of water
    in the area.” Wayman v. Murray City Corp.,

    Opinion of the Court
    First, it argues that none of the Plaintiffs established interference
    because they offered no evidence showing they were unable to get
    some quantity of their respective water rights. Second, Pineview
    argues that the district court erred in concluding the Plaintiffs’
    means of obtaining their water was reasonable. And finally,
    Pineview argues that the district court’s damages assessment was
    wrong. We address the Arave Well and then the Snowberry Well,
    applying the prima facie case outlined above.
    A. Arave Well
    ¶37 The district court correctly found that the Araves and
    Southwick12 satisfied the first, second, and fifth elements of an
    interference claim: specifically, that the Plaintiffs possess
    enforceable water rights, those rights are senior to Pineview’s
    water rights, and Pineview’s pumping of Well 4 hindered the
    Plaintiffs’ ability to get their water because it dropped the water
    table below the level of the Arave Well’s pump. However, the
    court made insufficient findings to establish that the Plaintiffs’
    method and means of diversion were reasonable (the third
    element). Consequently, the court could not properly conclude
    that despite reasonable efforts, the Plaintiffs were unable to obtain
    some quantity of their water rights (the fourth element). For these
    reasons, we reverse the district court’s interference determination.
    ¶38 With regard to the first element of an interference claim,
    Pineview does not dispute that the Araves and Southwick possess
    lawfully appropriated water rights. However, Pineview contends
    that the district court essentially granted the Plaintiffs a right to a
    certain level of the water table, to which they have no enforceable
    right. Pineview correctly characterizes the district court’s
    conclusions. The court ruled that:
    [Pineview’s] interference consists of dewatering the
    aquifers that are the source of supply for the Arave
    and [Snowberry] wells, thus obstructing and
    hindering the quantity of water available to the
    Arave and [Snowberry] wells, first by depriving the
    Arave well of virtually all water, and by obstructing
    the [Snowberry] well’s ability to produce water.

    Well, when we refer to the “Plaintiffs,” we mean Arave and
    Southwick.

    ARAVE V. PINEVIEW
    Opinion of the Court
    ¶39 Pineview relies on our decision in Bingham v. Roosevelt
    City Corporation, for its contention that the Plaintiffs have no
    enforceable right to the level of the water table. See 
    2010 UT 37
    ,
    ¶ 12. In Bingham, the plaintiffs sued the city, alleging that its
    manner of diverting water had reduced the level of soil saturation
    beneath the plaintiffs’ properties, thereby impairing their ability
    to raise crops and livestock. Id. ¶¶ 1, 5–6. Significantly, the
    plaintiffs had not appropriated the water in the soil. Id. ¶¶ 29, 36.
    Nevertheless, they argued that the level of soil saturation was a
    component of the water rights that they had appropriated because
    it allowed them to use the appropriated water more beneficially.
    Id. ¶¶ 20, 25. In other words, the plaintiffs required less water to
    irrigate their land before the city’s diversion had lowered the
    water table. Id. ¶ 20. We affirmed the district court’s grant of
    summary judgment in favor of the city, reasoning that beneficial
    use of water does not substitute for appropriation. Id. ¶¶ 29–30.
    Thus, because the plaintiffs had not appropriated the water in
    their soil, they did not have an enforceable right to its continued
    presence. Id. We also explained that the plaintiffs had sustained
    no compensable injury because they were still able to access all of
    the water to which they were entitled under their water rights. Id.
    ¶¶ 49–50.
    ¶40 The circumstances here are different than those in
    Bingham. Here, the Plaintiffs each have lawfully appropriated
    water rights, allowing them to divert water from their respective
    wells. They are not claiming an enforceable right to use additional
    unappropriated water simply because it is present in their soil. Cf.
    id. ¶ 24. Instead, they seek to enforce their existing senior water
    rights. And although we held in Bingham that the plaintiffs had no
    enforceable right to the water in their soil, we recognized that “a
    claim of interference can be sustained where a junior appropriator
    lowers the water table in a manner that hinders the diversion of
    water by a senior appropriator.” Id. ¶ 51.
    ¶41 We conclude that the Plaintiffs have satisfied this element
    of an interference claim because they have lawfully appropriated
    water rights. But we clarify that the Plaintiffs have an enforceable
    right only in these lawfully appropriated water rights—not in a
    particular level of the water table. The Plaintiffs’ claim that
    Pineview’s dewatering of the aquifer constitutes actionable
    interference cannot be divorced from the requirement that the
    Plaintiffs make reasonable efforts to obtain their water.
    Fundamentally, the Plaintiffs must show that because of the
    actions of Pineview, they can no longer access the water to which
    12
    Cite as: 
    2020 UT 67
    Opinion of the Court
    they are entitled even though they have made reasonable efforts
    to do so. If they cannot make such a showing, they have
    demonstrated only that Pineview has lowered the water table, not
    that it has prevented them from obtaining some quantifiable
    portion of their water right.
    ¶42 With regard to the second element, it is undisputed that
    the Araves’ and Southwick’s water rights are senior to Pineview’s.
    ¶43 However, with regard to the third element, we conclude
    that the district court did not find sufficient facts to establish that
    the Plaintiffs’ method and means of diversion were reasonable.
    This element is based upon the rule of reasonableness, which
    requires that each appropriator’s “means of diversion must be
    reasonable and consistent with the state of development of water
    in the area.” Wayman, 458 P.2d at 866. The rule of reasonableness
    permits the factfinder a measure of flexibility in considering the
    totality of relevant facts—such as the quantity of water available,
    the average annual recharge, the existing rights that are in
    conflict, and their relative priorities—with the objective of putting
    the greatest amount of water to beneficial use. Id. at 865. As we
    explained in Wayman, all water users are required to “employ
    reasonable and efficient means in taking their own waters in
    relation to others to the end that wastage of water is avoided and
    that the greatest amount of available water is put to beneficial
    use.” Id.
    ¶44 Here, the district court concluded, the “Plaintiffs‘ means
    and method of diverting their water are reasonable. Their wells
    are the only possible method for diverting the water under their
    rights. Those wells functioned without problem until [Well 4] was
    drilled.”
    ¶45 These findings are not sufficient to establish that the
    operation of the Arave Well was reasonable during the relevant
    time period. The district court appears to have based its
    conclusion on two findings: first that the Araves can divert their
    water only through the use of the well based on the terms of their
    water right, and second that the well functioned without issue
    until Well 4 began to operate. Those facts are certainly relevant to
    the reasonableness question, but they do not complete the
    analysis. It is also necessary to consider whether the Araves were
    operating the well efficiently and consistent with the current state
    of development in the area, and to identify and consider any other
    factors relevant to maximizing the beneficial use of water.
    13
    ARAVE V. PINEVIEW
    Opinion of the Court
    ¶46 Here, the record evidence established that although the
    water table dropped when Well 4 pumped, “there ha[d] not been
    a general decline in groundwater levels in the regional basin in
    which [the] aquifers are located,” although it fluctuated
    seasonally. Under these circumstances, it was necessary to
    determine whether the Plaintiffs made reasonable efforts to obtain
    the available water but were unable to do so. However, the court
    did not make findings related to whether the Plaintiffs could have
    lowered their pump or otherwise modified the well to reach the
    available water, or conversely, explain why this would have been
    futile or otherwise not possible.13 Without this, there are not
    adequate findings to establish that the Plaintiffs made reasonable
    efforts to obtain their water.
    ¶47 While the Plaintiffs’ failure to meet the requirements of
    the third element is dispositive, we note that the third and fourth
    elements are closely related. If the Plaintiffs cannot demonstrate
    that their means and method of diversion are reasonable, it is
    impossible to satisfy the fourth element of the prima facie case—
    that despite reasonable efforts, the Plaintiffs could not obtain the
    quantity of water to which they were entitled.
    ¶48 We note an additional problem with the Plaintiffs’ proof
    on the fourth element. The district court did not make findings
    about the specific amount of their respective water rights that the
    Araves and Southwick were unable to obtain. Rather, the court
    found that Pineview’s operation of Well 4 interfered with the
    Plaintiffs’ well. But this does not necessarily establish that the
    Plaintiffs were unable to obtain some quantity of their water right.
    ¶49 The Plaintiffs did not offer evidence of how much water
    they used or how much of their appropriated water they were not
    able to obtain. This is because the Araves did not have a metering
    device in their well. We do not mean to suggest that it was
    __________________________________________________________
    13 Rather, the court found that the Araves removed the pump
    and used the well as a monitoring well to document the impact of
    pumping Well 4. The court accepted the Plaintiffs’ explanation
    that if they had pumped the well at the same time, it would have
    been more difficult to interpret the data. While this may be the
    case, it does not excuse the Araves from showing that at some
    point after the alleged interference, they made reasonable efforts
    to reach available water but were unable to do so.
    14
    Cite as: 
    2020 UT 67
    Opinion of the Court
    impossible for Plaintiffs to show interference by proving that
    Pineview interfered with the year-round nature of their water
    rights. But it is difficult for them to establish that Pineview
    prevented them from obtaining some quantifiable amount of the
    water to which they were entitled with no measurements of the
    amount of water they could obtain at the time of the alleged
    interference.
    ¶50 In sum, we conclude there are insufficient findings to
    establish that the Plaintiffs’ means of diversion was reasonable
    and that despite their reasonable efforts the Plaintiffs were unable
    to obtain some quantity of their water rights. Accordingly, we
    reverse the district court’s ruling that Pineview interfered with the
    Arave Well.
    B. Snowberry Well
    ¶51 With regard to the Snowberry Well, Pineview argues that
    because Venture exceeded the terms and limits of its senior water
    right,14 it cannot make a viable interference claim. In other words,
    Pineview asserts that Venture’s water use was illegal, and any
    alleged interference with an illegal use is not actionable. Pineview
    further argues that Venture did not prove it was unable to obtain
    the water to which it was entitled under its original, senior water
    right. We reject the first argument, but we agree that the district
    court did not make sufficient findings to establish that Pineview
    could not obtain some portion of its senior water right.
    ¶52 Pineview argues that Venture’s excessive water use is
    fatal to its interference claim. This relates to the first element of
    the prima facie case. Pineview essentially argues that Venture’s
    violation of its water right renders it unenforceable. We reject this
    argument. While excessive use may make it more difficult for
    Venture to prove that it could not obtain the water allotted to it
    under its 1960 right and that its diversion was reasonable, Venture
    has not lost its water right. Certainly, it risked an enforcement
    action by the state engineer. See UTAH CODE § 73-2-25(2)(a). But if
    Venture can make out a claim for interference, its excessive use
    would not bar such an action or shield Pineview from liability.
    __________________________________________________________
    14Venture not only used more water than it was allotted, but
    used it to support a commercial bed-and-breakfast and to irrigate
    when it was entitled to use its water only for domestic purposes.
    15
    ARAVE V. PINEVIEW
    Opinion of the Court
    ¶53 However, we agree with Pineview that Venture has not
    proven interference. With regard to the first element, it is
    undisputed that Venture has an enforceable 1960 water right that
    allows it to divert 0.45 acre-feet of water at a flow rate of 6.7
    gallons per minute from the Snowberry Well for single-family
    domestic use.
    ¶54 Second, this water right is senior to both of Pineview’s
    water rights. Because Venture exceeded the limits and terms of
    this senior water right, it obtained an additional water right from
    the state engineer. The new 2017 water right is junior to
    Pineview’s rights and is not part of Venture’s interference claim.
    ¶55 Third, with regard to reasonableness, the district court
    made the same finding for both wells. As described above, the
    court concluded that the “Plaintiffs’ means and method of
    diverting their water are reasonable. Their wells are the only
    possible method for diverting the water under their rights. Those
    wells functioned without problem until [Well 4] was drilled.” For
    the reasons we explained above, this is insufficient to establish
    that the Snowberry Well was a reasonable means of diversion in
    the manner in which Venture operated it. See supra ¶¶ 43–45.
    ¶56 This impacts Venture’s ability to satisfy the fourth
    element. As we have explained, without a sufficient finding of
    reasonableness, Venture cannot show that despite reasonable
    efforts it was unable to obtain its water. See supra ¶¶ 46–48.
    ¶57 And while this is determinative, we also note that the
    district court’s findings regarding Venture’s inability to obtain
    some measure of its water right were insufficient. While the
    district court found that Well 4 hindered the Snowberry Well’s
    ability to produce water, it did not specifically find that Venture
    was unable to obtain the quantity of water to which it was entitled
    under its senior water right. The findings state only that the
    Snowberry Well “struggles” when Well 4 operates. So we do not
    know whether Venture was ultimately unable to obtain some
    portion of the 0.45 acre-feet of water allotted to it under its 1960
    right. This is especially problematic where Venture used more
    than its allotted right.
    ¶58 Accordingly, we reverse the district court’s determination
    that Pineview interfered with the Snowberry Well.
    II. NEGLIGENCE
    ¶59 Pineview next contends that the district court erred in
    concluding it was negligent in locating, drilling, and using Well 4.
    16
    Cite as: 
    2020 UT 67
    Opinion of the Court
    The district court concluded Well 4 operates in a manner that
    interferes with the Arave and Snowberry Wells and that such
    harm was foreseeable due to Well 4’s close proximity to the
    Plaintiffs’ wells, its use of the Plaintiffs’ water source, and its
    larger capacity.
    ¶60 First, Pineview argues that this ruling is erroneous
    because it was not Pineview but other developers who sited,
    drilled, and tested Well 4 and the Plaintiffs did not join those
    developers in this case. But even assuming Pineview did not site
    or drill Well 4, it does currently own and operate the well. And
    Pineview provides no argument or authority as to why the
    current operator of a well should be insulated from liability for
    negligence because it did not originally site and drill the well.
    Likewise, Pineview does not provide any legal argument or
    authority as to why not joining the prior developers is fatal to the
    Plaintiffs’ negligence claim against Pineview.
    ¶61 Pineview also asserts that the Plaintiffs’ negligence claim
    fails because they did not offer expert testimony establishing the
    relevant standard of care and causation. But Pineview has not
    explained why the Plaintiffs were obligated to present expert
    testimony to establish causation or the standard of care in this
    case. Pineview cites Ladd v. Bowers Trucking, Inc. to assert that
    “Utah courts generally require expert testimony to prove
    causation in tort cases in all but the ‘most obvious cases.’” 
    2011 UT App 355
    , ¶ 10, 
    264 P.3d 752
     (citation omitted). While that
    language was accurate in context—proving causation of medical
    injuries—we have also explained that “[q]uestions of ordinary
    negligence are properly determined by the lay juror without the
    need for expert testimony.” Graves v. N. E. Servs., Inc., 
    2015 UT 28
    ,
    ¶ 40, 
    345 P.3d 619
    . Expert testimony is necessary only for “issues
    that do not fall within the common knowledge and experience of
    lay jurors.” Callister v. Snowbird Corp., 
    2014 UT App 243
    , ¶ 19, 
    337 P.3d 1044
    . Yet Pineview has failed to specify which matters are
    beyond the capacity of the factfinder in this case.
    ¶62 By failing to adequately analyze or argue either point,
    Pineview has failed to meet its burden of persuasion and has
    shifted the burden of research and argument to this court. See
    Smith v. Four Corners Mental Health Ctr., Inc., 
    2003 UT 23
    , ¶ 46, 
    70 P.3d 904
    . Under rule 24(a)(8) of the Utah Rules of Appellate
    Procedure, an appellant’s argument “must explain, with reasoned
    analysis supported by citations to legal authority and the record,
    why the party should prevail on appeal.” This briefing
    17
    ARAVE V. PINEVIEW
    Opinion of the Court
    requirement is “a natural extension of an appellant’s burden of
    persuasion.” Living Rivers v. Exec. Dir. of the Utah Dep’t of Env’t.
    Quality, 
    2017 UT 64
    , ¶ 33, 
    417 P.3d 57
     (citation omitted). Thus,
    “[a]n appellant who fails to adequately brief an issue will almost
    certainly fail to carry its burden of persuasion on appeal.” 
    Id.
    (citation omitted) (internal quotation marks omitted).
    ¶63 Accordingly, we decline to reverse the district court’s
    negligence ruling. However, in light of our reversal of the district
    court’s interference determinations, we remand this claim for
    reconsideration and further factfinding, if necessary. This is
    because the district court’s negligence determination flows from
    its finding of interference. The district court concluded that
    Pineview had breached a duty of care to the Plaintiffs when it
    “located, drilled, and used [Well 4] in a manner that interferes with
    plaintiffs’ wells.” (Emphasis added.) It is not clear how our reversal
    of the Plaintiffs’ interference claims impacts the district court’s
    negligence ruling. Accordingly, we remand for the district court
    to consider that question and make any additional findings of fact
    that it deems necessary.
    III. DAMAGES
    ¶64 We also remand to the district court its calculation of
    damages and imposition of prospective remedies. The court
    should determine whether these are altered by the reversal of its
    interference determinations. Any damages now stem only from
    the Plaintiffs’ negligence claim.
    ¶65 Additionally, we vacate a portion of the court’s
    compensatory damages award. Pineview argues the damages
    award is excessive to the extent the district court required
    Pineview to refund water service fees paid by the Plaintiffs for
    periods when Well 4 was inactive and therefore did not impact
    the Plaintiffs’ ability to obtain water. We agree. The evidence
    presented at trial established that Well 4 pumped only seasonally
    and the Plaintiffs’ wells recovered within a day or two after Well 4
    ceased pumping. In assessing the damages caused by Pineview’s
    negligence, the court should award damages only for fees paid
    during the period of the year that Well 4 injured the Plaintiffs’ use
    of their wells. Accordingly, we vacate the portion of the damages
    award that compensates the Plaintiffs for fees paid during periods
    in which their wells would have been unimpeded by Well 4 if
    they had attempted to use them.

    Opinion of the Court
    IV. ATTORNEY FEES
    ¶66 Pineview requests attorney fees under Utah Code
    sections 73-2-28(4) and 78B-5-825. Because we affirm the district
    court’s judgment that Pineview was negligent, we conclude that
    Pineview is not entitled to attorney fees on appeal.
    CONCLUSION
    ¶67 We reverse the district court’s determination of
    interference regarding the Arave and Snowberry Wells. In light of
    this, we remand the court’s determination of negligence for
    reconsideration and further factfinding, as the court deems
    necessary. We vacate the damages award to the extent that it
    compensates the Plaintiffs for fees paid during periods of the year
    when Pineview did not utilize Well 4. And finally, we remand to
    the district court to determine whether to revisit its damages
    award and imposition of remedies in light of the reversal of its
    interference determinations.
