                                          -ooOoo-
       Over 20 years ago, the first lawsuits were filed that ultimately evolved into this
proceeding known as the Antelope Valley Groundwater Cases (AVGC). The AVGC
proceeding litigated whether the water supply from natural and imported sources, which
replenishes an alluvial basin from which numerous parties pumped water, was inadequate
to meet the competing annual demands of those water producers, thereby creating an
“overdraft” condition. Numerous parties asserted that, without a comprehensive
adjudication of all competing parties’ rights to produce water from and a physical
solution for the aquifer, this continuing overdraft would negatively impact the health of
the aquifer. Phelan Piñon Hills Community Services District (Phelan) ultimately became
involved in the litigation as one of the thousands of entities and people who asserted they
were entitled to draw water from the aquifer.
       After the Judicial Council ordered all then-pending lawsuits consolidated into this
single adjudication proceeding, the trial court embarked on an 11-year process in which
it, seriatim, defined the geographical boundaries for the Antelope Valley Adjudication
Area (AVAA) to determine which parties would be necessary parties to any global
adjudication of water rights, and then determined that the aquifer encompassed within the
AVAA boundaries (the AVAA basin) had sufficient hydrologic interconnectivity and
conductivity to be defined as a single aquifer for purposes of adjudicating the competing
groundwater rights claims. Its next phase found the AVAA basin was in a state of
chronic overdraft because extractions exceeded the basin-wide annual “safe yield” of
110,000 acre-feet per year (afy) by a considerable margin. The next phase quantified
how much water was currently being pumped by each of the major competing water

                                             3.
rights claimants; these annual extractions (even without considering the amounts
extracted by a large class of overlying right holders known as the “Small Pumper Class”)
were in excess of the safe yield for the AVAA basin. The next phase, which
contemplated trial of the issues of federal reserved water rights and imported water return
flow rights, was interrupted by settlement discussions, which ultimately produced an
agreement among the vast majority of parties in which they settled their respective
groundwater rights claims and agreed to support the contours of a proposed plan (the
Physical Solution) designed to bring the AVAA basin into hydrological balance.
       Phelan was not among the settling parties. Accordingly, before considering
whether to approve the proposed global water allocations and Physical Solution for the
AVAA basin, the court first conducted separate trials at which Phelan’s claims were
litigated and resolved. Thereafter, the court held a trial on the rationale for and efficacy
of the proposed Physical Solution. After finding the proposed Physical Solution was
reasonable, fair and beneficial as to all parties, and served the public interest, the court
approved the Physical Solution.
       Phelan, which provides water to its customers who are located outside the AVAA
boundaries, became subject to the AVGC litigation because a significant source of its
water is pumping from a well (Well 14) located in the AVAA basin. The court’s
judgment and adopted Physical Solution concluded that, while Phelan held no water
rights in the AVAA basin (either as an appropriator of a surplus or by prescription),
Phelan could continue operating Well 14 to draw up to 1,200 afy to distribute to its
customers outside the AVAA, on condition that Phelan’s pumping causes no material
harm to the AVAA basin and that Phelan pays a “Replacement Water Assessment” for
any water it pumped for use outside the AVAA.
       Phelan challenges the judgment, raising four claims of error. First, Phelan asserts
there is no substantial evidence to support the trial court’s conclusion the Physical
Solution will bring the AVAA basin into hydrological balance. Second, it argues the trial

                                              4.
court erred when it rejected Phelan’s claim that, even assuming the AVAA basin was in
overdraft, Phelan was entitled to water rights in the AVAA basin as an “appropriator for
municipal public use” under Water Code sections 106 and 106.5. Third, Phelan asserts
that, assuming the existence of a “surplus” in the AVAA basin was a condition precedent
to Phelan’s acquisition of water rights as an appropriator, the phasing of the various trials
denied Phelan its due process rights to establish the AVAA basin did have a surplus at the
time Phelan began operating Well 14. Finally, Phelan contends the trial court erred when
it rejected its claim that it was entitled to credit for “return flows” and erred by imposing
a Replacement Assessment Fee based on the gross amount of water extracted by Well 14.
       We conclude substantial evidence supports the judgment as to Phelan, that the
court correctly rejected Phelan’s claim it had cognizable water rights as an appropriator
for municipal purposes, that Phelan was not deprived of its due process rights to present
its claims, and that the court did not err in rejecting Phelan’s claim to return flows from
native water it pumped from the AVAA basin. Accordingly, we will affirm the judgment
as to Phelan.
                     FACTUAL AND PROCEDURAL HISTORY
Factual Setting
       There is a single aquifer, consisting of several hydrologically interconnected
subbasins, underlying the AVAA. That aquifer was in a state of overdraft—meaning that
long-term extractions from the aquifer have exceeded the amount of water replenishing
that aquifer by “significant margins”—and had been in overdraft for decades before the
current litigation commenced in 1999. While localized conditions led to variable impacts
from this overdraft within specific subportions of the AVAA, the overall water levels
within the AVAA basin were declining, and the declining water levels have caused
significant long-term damage, including subsidence and lost aquifer storage capacity.
The estimated average annual safe yield from all sources of recharge (natural sources
such as precipitation, external sources such as imported water, and return flows) was

                                              5.
110,000 afy for the AVAA basin, but the numerous parties who pumped water from that
basin were annually extracting between 130,000 and 150,000 afy.
       Phelan owns a parcel within the boundaries of the AVAA on which it operates
Well 14. In late 2005, it started operating Well 14 and extracting water from the AVAA
basin, and it first delivered water from Well 14 to its customers in 2006. Phelan is a
public agency organized as a community services district supplying water to over 21,000
residents, nearly all of whom use it for domestic uses, and Phelan’s source for the water it
distributes is from groundwater pumped from its various wells. Phelan’s entire service
district is outside the AVAA, although a portion of its service district and some of its
customers overlay a portion of the alluvial basin defined by the California Department of
Water Resources’ Bulletin 118 as the “Antelope Valley Groundwater Basin” (AVGB).
The Litigation Commences
       Between late 1999 and early 2000, the first lawsuits (which ultimately evolved
into the AVGC) were filed by Diamond Farming Company and Wm. Bolthouse Farms,
Inc., concerning competing water rights in the aquifer. These actions, styled as quiet title
actions against various public water suppliers, sought a determination of the various
rights and priorities of overlying landowners and others claiming rights to extract water
from the AVAA basin. Over the next several years, additional complaints and cross-
complaints were filed, which evolved into the AVGC and which sought a comprehensive
determination of the water rights of thousands of persons, companies, public water
suppliers, and the federal government, as well as a physical solution to alleviate the
alleged overdraft conditions in the AVAA and to protect the AVAA basin.
Phase 1: Determining the Geographic Boundaries of the AVAA
       The trial court segmented the various issues raised by the actions and held trials on
these issues in phased proceedings. In October 2006, the court conducted trial to
establish the jurisdictional boundaries for the AVAA. Establishing the boundaries was
essential in order to determine what parties and entities with claims to the groundwater

                                             6.
would be necessary parties in the litigation, as either overlying owners with usufructuary
rights or as appropriators producing water from the aquifer, so that a comprehensive
adjudication of all claims could be made in later proceedings. After hearing expert
testimony, the court determined the boundaries of the alluvial basin as defined by the
California Department of Water Resources’ Bulletin 118 should be the “basic”
jurisdictional boundaries for the AVAA, although it set the easternmost boundary for the
AVAA at the jurisdictional line that had been previously established as the westernmost
boundary in the “Mojave litigation.” The court left open the possibility that areas
presently encompassed within the AVAA might be excluded (if shown to lack any real
connection to the AVAA aquifer), or other areas might be included, as might be
warranted by further evidence.
Phase 2: Determining Hydraulic Connectivity Within the AVAA Boundaries
       In the second phase, the court heard evidence to assess the hydrologic nature of
the aquifer within the geographical boundaries set for the AVAA. The court specifically
evaluated whether there were any distinct subbasins within the AVAA basin that lacked
any hydrologic connection such that they should be treated as separate, unconnected
basins for purposes of adjudication. The court concluded there was enough hydraulic
connectivity within the AVAA basin as a whole to obviate any claim that certain sections
should be treated as separate basins.
Phelan Intervenes
       In late 2008, Phelan filed its cross-complaint alleging seven causes of action.
Among its claims were (1) Phelan had an appropriative right to pump water from the
AVAA because there was surplus water in that the basin’s safe yield exceeds the volume
pumped from the basin; (2) Phelan had “municipal priority” rights under California law
“both as a result of the priority and extent of its appropriative and prescriptive rights, and
as a matter of law and public policy” under statutory law; (3) Phelan had the right to the
“recapture of return flows”; and (4) that some parties’ use of water was unreasonable and

                                              7.
constituted “waste, unreasonable use or an unreasonable method of diversion or use,” and
such parties’ water rights should be determined and limited to reasonable uses rather than
actual uses.
Phase 3: Determining Safe Yield and Overdraft
       In the Phase 3 trial, the parties litigated the safe yield for the AVAA basin and
whether the area encompassed within the AVAA was in overdraft.1 The Public Water
Suppliers2 (PWS), along with numerous other parties, contended the average annual
extractions from the AVAA basin exceeded the relevant safe yields and that it was in
overdraft. It proffered extensive testimony on average annual recharge, annual
extractions, and the deleterious impacts from the chronic overdraft of the AVAA basin.
       Phelan did not contest the contentions of the PWS in Phase 3 that the AVAA basin
was in overdraft. Instead, Phelan sought to proffer evidence from its expert, Thomas
Harder, concerning his study of the conditions in an area that encompassed both a
southeast corner of the AVAA basin as well as land outside the boundaries of the AVAA.

       1In   the context of an alluvial basin, “safe yield” is defined as “‘the maximum quantity of
water which can be withdrawn annually from a ground water supply under a given set of
conditions without causing an undesirable result.’ The phrase ‘undesirable result’ is understood
to refer to a gradual lowering of the ground water levels resulting eventually in depletion of the
supply.” (City of Los Angeles v. City of San Fernando (1975) 14 Cal.3d 199, 278, disapproved
on other grounds in City of Barstow v. Mojave Water Agency (2000) 23 Cal.4th 1224, 1248.) In
essence, “safe yield” examines the available groundwater recharge from replenishing sources
such as native precipitation and associated runoff, along with return flows from such sources,
less losses incurred through natural groundwater depletions such as subsurface outflow or
evaporative losses. (City of Los Angeles, supra, at pp. 278–279; see Tehachapi–Cummings
County Water Dist. v. Armstrong (1975) 49 Cal.App.3d 992, 996, fn. 3 [“Natural ‘safe yield’ is
the maximum quantity of ground water, not in excess of the long-term, average, natural
replenishment (e.g., rainfall and runoff), which may be extracted annually without eventual
depletion of the basin”].) “Overdraft” examines whether the average annual withdrawals or
diversions exceed the safe yield of a groundwater supply and would lead to ultimate depletion of
the available supply. (Jordan v. City of Santa Barbara (1996) 46 Cal.App.4th 1245, 1272.)

City of Palmdale, Littlerock Creek Irrigation District, Los Angeles County Waterworks District
No. 40, Palmdale Water District, Rosamond Community Services District, Palm Ranch Irrigation
District, and Quartz Hill Water District.

                                                8.
Phelan contended (consistent with the PWS position) Mr. Harder would confirm that the
area he studied showed pumping by Phelan and others has resulted in declining water
levels in the southeast portion of the AVAA, and that “overdraft exists in the Southeast
area of the [AVAA], or will exist in the near future, if groundwater pumping in this area
continues at current rates or increases.”3
       The court found the AVAA basin was in a state of overdraft, and that average
extractions had significantly exceeded average recharge for decades, causing a steady
lowering of water levels and accompanying subsidence since 1951. The court concluded
the average total safe yield from all sources4 was 110,000 afy for the AVAA as a whole,
while current actual extractions from the AVAA as a whole (ranging between 130,000
and 150,000 afy) exceeded average annual recharge. Accordingly, the court found (1) the
AVAA was in overdraft and (2) the annual safe yield was a total of 110,000 afy.
Phase 4: Determining Actual Groundwater Production by Claimants
       In the next phase, the court ultimately determined it would limit trial to
individualized determinations of how much water the various claimants actually pumped

       3The court ultimately ruled that, while Harder could testify about impacts of pumping
from Well 14 because it was sited within the AVAA jurisdictional boundaries, the bulk of
Harder’s proffered testimony would be excluded from the Phase 3 trial because Harder’s
testimony was principally focused on pumping and return flows in areas outside the boundaries
of the AVAA.
       4It appears the total annual safe yield ultimately set by the court as the appropriate
“quantity of pumping from the basin [that] will maintain equilibrium in the aquifer” was an
amalgamation of two different components: amounts attributable to “native” water and amounts
attributable to “imported” water. Various experts testified that native water additions (i.e., water
coming into the basin from precipitation and runoff) provided new water to the AVAA basin
ranging between 55,000 to 68,000 afy. When “return flows” from that new water were
calculated, the PWS contended the native safe yield should be set at approximately 82,300 afy
for the AVAA basin as a whole. However, various entities also imported additional water into
the AVAA, and when that imported water (along with its return flows) was added to the native
supply, the total safe yield for the AVAA basin was determined by the court to be 110,000 afy.

                                                 9.
from the AVAA basin during the years 2011 and 2012.5 Based on the stipulations and
evidence presented by numerous parties about the amounts pumped during the relevant
time frames, including Phelan’s evidence that it pumped 1,053.14 acre-feet in 2011 and
1,035.26 acre-feet in 2012 from the AVAA basin, the court determined how much water
the various major stakeholders actually pumped from the AVAA basin in the relevant
years. The amounts actually pumped during those sample years exceeded the previously
determined safe yield.6
Commencement of Phase 5: Federal Reserve Rights and Imported Water Return Flow
Rights
       The Phase 5 trial bifurcated two issues for the next trial phase: (1) federal
reserved water rights, and (2) any claimed rights to recapture and use any return flows
from water imported into the AVAA. However, during the evidentiary presentations on
the federal reserved water rights, the parties requested a recess of pending proceedings to

       5Initially, the case management order (CMO) for the Phase 4 trial contemplated it would
encompass a vast array of issues, including the issue ultimately tried (current groundwater
production for the two-year period which preceded the Phase 4 trial), but it also contemplated the
trial would litigate each pumper’s claimed reasonable and beneficial use of water the water
pumped, as well as claimed return flows from imported water and federal reserved rights.
However, that CMO subsequently evolved to narrow the issue tried in Phase 4 and provided that
“proof of claimed reasonable and beneficial use of the water for each parcel to be adjudicated”
would only encompass “the amount of water used by each party and the identification of the
beneficial use to which that amount was applied, but will not include any determination as to the
reasonableness of that type of use [or] of the manner in which the party applied water to that
use ….” The fifth amended CMO ultimately provided the “Phase [4] Trial is only for the
purpose of determining groundwater pumping during 2011 and 2012. The Phase [4] Trial shall
not result in any determination of any water right, or the reasonableness of any party’s water use
or manner of applying water to the use. The Phase [4] Trial will not preclude any party from
introducing in a later trial phase evidence to support its claimed water rights …. All parties
reserve their rights to produce any evidence to support their claimed water rights and make any
related legal arguments including, without limitation, arguments based on any applicable
constitutional, statutory, or decisional authority.”
       6The court found that, during the sampled years, the parties cumulatively pumped in
excess of 120,000 afy even before consideration of the amounts pumped by the “Wood Class,”
and apparently without consideration of the amount that would be subject to any federal reserved
right.

permit further settlement discussions. The parties then met and conducted settlement
discussions, and in April 2014, the parties informed the court that the vast majority of the
parties had reached a proposed global settlement of their respective groundwater claims.
The settlement included agreement on the contours of a basin-wide groundwater
management plan to implement a Physical Solution to the AVAA basin’s overdraft
conditions that accommodated the groundwater rights of the parties to the global
settlement.
       Although Phelan participated in the settlement negotiations, the parties were
unable to reach agreement settling Phelan’s claims to water from the AVAA basin.
Trial of Phelan’s Preserved Claims
       Because the parties were unable to reach a satisfactory agreement to accommodate
Phelan’s claims to pump water from the AVAA basin for use outside the AVAA, the
court set a series of trials in which to litigate and resolve Phelan’s claims for relief.
       “Stage One”: Trial on Phelan’s Preserved Claims for Appropriative and Return
       Flow Rights
       The court held hearings and conferences to delineate which of the claims raised by
Phelan’s cross-complaint should be tried next.7 The court opined the appropriate scope

       7In  its case management statements, Phelan indicated it had abandoned its claim of a
prescriptive water right, but had seven remaining causes of action. Phelan identified three key
issues that should be litigated in the next stage. First, Phelan asserted it had obtained an
appropriative water right to pump from Well 14 as an appropriator of surplus water; it asserted
there was a “local area” surplus in the portion of the AVAA where its Well 14 was sited because
groundwater levels in the Buttes and Pearland subbasins had not changed significantly since
1951, which it contended showed a lack of overdraft in those two subbasins. Phelan
alternatively asserted it was an appropriator for public use of nonsurplus water. Phelan also
asserted a form of return flow “rights,” arguing that the evidence would show that some of the
water drawn from the AVAA basin by Well 14 returned to the AVAA basin, and that
consideration of this return flow should be factored into “the overall water balance with [Phelan]
receiving an offset against potentially future assessments or liabilities, anti-export provisions, or
otherwise arising from the anticipated physical solution to be fashioned by the Court.” (Italics
omitted.) Finally, Phelan argued that although the jurisdictional boundaries established for the
AVAA excluded Phelan’s service area, the hydrogeologic reality was that the aquifer extended
eastward (crossing over the AVAA boundaries) to encompass part of Phelan’s service area, and

                                                 11.
of issues to be tried in the first stage should include (1) whether Phelan could show it had
acquired an appropriative water right by showing there was a surplus in the AVAA
basin,8 and (2) whether Phelan could establish a return flow right from native waters that
provided some support for Phelan’s claims.
       Trial on these aspects of Phelan’s preserved claims occurred in late 2014. The
parties agreed on a set of stipulated facts and exhibits. Phelan also introduced the
testimony of two witnesses, including its expert hydrogeologist, Mr. Harder. The court
then heard argument on and ultimately granted cross-defendants’ motions for judgment.
It issued a partial statement of decision on the stage one issues, which found Phelan had
no appropriative right to pump from the AVAA basin because Phelan had not satisfied its
burden of proof to show there was surplus water available for an appropriative use. The
court specifically found the Butte subbasin (where Phelan’s Well 14 is located) was
adjacent to and hydrologically connected with other parts of the AVAA basin and served
as a source of water recharge for the overall AVAA basin. It further found that localized

this fact should be accounted for in determining (1) whether Phelan’s use of Well 14 water
within its service area was subject to any anti-export prohibition and (2) whether Phelan could be
credited for recaptured return flows. Thus, it appears Phelan sought trial on its second cause of
action (appropriative rights to surplus water), its fourth cause of action (municipal priority to
water use as against all nonmunicipal users), its sixth cause of action (declaratory relief
regarding return flows from water extracted and distributed by Phelan in its service area), and
elements embedded in its eighth cause of action (declaratory relief on the boundaries of the
basin).
       8The parties  discussed the relevance of testimony concerning water levels in the Butte
subbasin. Specifically, the parties sought to determine whether, in light of the court’s decisions
in Phase 2 (that there was sufficient hydraulic connectivity within the AVAA aquifer as a whole
to obviate the claims that certain sections should be treated as separate basins) and Phase 3 (that
the AVAA basin as a whole was in overdraft), Phelan’s evidence concerning water levels in one
portion of the AVAA (the Butte subbasin where Well 14 is located) was germane to Phelan’s
attempt to show a surplus existed in the AVAA as whole when it brought Well 14 online. The
court observed that Phelan had not previously proffered evidence that the Butte subbasin was a
totally separate basin lacking hydrologic connectivity to the overall AVAA basin, and therefore
opined that demonstrating surplus for the AVAA as a whole (rather than in a particular section)
would be required, but recognized Phelan “may have other evidence [or] may be able to
demonstrate, as a matter of law, that it doesn’t matter.”

                                                12.
variations in groundwater levels within portions of the basin were insufficient to
demonstrate there was surplus water in the overall AVAA basin upon which Phelan could
acquire an appropriative right to water from the basin. The court also rejected Phelan’s
sixth cause of action, ruling Phelan had no cognizable right to pump return flows
attributable to native waters that recharged the AVAA basin.
       Stage Two: Trial of Phelan’s Remaining Preserved Claims
       The court then scheduled a trial for Phelan’s remaining claims for August 2015.9
Phelan delineated those remaining claims as seeking declarations (1) as to its alleged
appropriative rights as a municipal water provider (fourth cause of action), (2) as to its
“storage” rights for imported water (fifth cause of action), and (3) as to the alleged
unreasonable use of water by other cross-defendants (seventh cause of action). Phelan
also sought a determination, on its third cause of action for a Physical Solution, that any
Physical Solution should allow Phelan to pump up to 1,200 afy without payment of any
Replacement Assessment Fee.10 Prior to this Stage Two trial, Phelan “reserved” its right
to present evidence on its “unreasonable use of water” claim and indicated it would
present that evidence at the pending “prove-up” hearings on the proposed Physical
Solution. Accordingly, Phelan framed the issues for the Stage Two trial to be limited to
whether Phelan had appropriative rights as a municipal water provider and whether any
Physical Solution should allocate certain amounts of pumping to Phelan free of any
replacement assessment.

       9The court’s   scheduling order also set an evidentiary hearing on a proposed Physical
Solution for the fall of 2015.
       10Although    Phelan also indicated (prior to the Stage Two trial) that it intended to pursue
its eighth cause of action for a declaration of the boundaries of the AVGB, it later expressly
stated this cause of action did not seek to revise the AVAA boundaries established in Phase 1,
but was instead limited to seeking a determination that it was not an “exporter” of the water it
drew from Well 14.

                                                 13.
       At this Stage Two trial, Phelan made a brief evidentiary presentation from its
expert hydrologist on the claims set for hearing.11 At the close of Phelan’s evidence
phase, a PWS party moved for judgment under Code of Civil Procedure section 631.8,
but the court deferred ruling on the motion until it could hear further evidence scheduled
to be heard during the Phase 6 trial on the Physical Solution.
Phase 6: The Physical Solution
       In the spring of 2015, the settling parties presented a stipulation containing a
proposed plan, the Physical Solution, for the entire AVAA, which was agreed upon by
the vast majority of the parties to the consolidated actions. Phelan was not among the
parties to the stipulation. The proposed judgment contained an allocation of the projected
safe yield among the numerous parties. Although the proposed judgment did not allocate
any share of the available native safe yield to Phelan, it did specify Phelan could continue
to pump up to 1,200 afy from Well 14 for use outside the AVAA as long as such
pumping did not cause “material injury” to the AVAA and Phelan paid a replacement
water assessment for the amounts it extracted from Well 14 and distributed outside the
AVAA.
       In the fall of 2015, the court held hearings on the proposed Physical Solution.
After hearing evidence from a historian on the public notoriety of the overdraft
conditions in the area,12 the court heard evidence from four experts concerning the

       11Harder identified   six wells used by Phelan to pump water from the AVGB, although
only one of those wells (Well 14) was within the AVAA. He also described the amounts of
water Phelan distributed to the portion of their customers who, although outside the AVAA, were
atop a portion of the alluvial basin as defined by the Department of Water Resources’ Bulletin
118. He also testified Phelan’s pumping has had no measurable impact on the groundwater
levels within the Buttes subbasin, and that groundwater levels within the Buttes subbasin has
remained relatively stable. However, Harder conceded that water pumped from Phelan’s wells
intercepted water that would otherwise flow as recharge into the AVAA basin.
       12Dr.   Douglas Littlefield, a forensic historian, testified to a long history of published
articles and technical studies showing the overdraft of water and resulting diminishing water

                                                 14.
proposed Physical Solution. Dr. Dennis Williams, an expert with extensive experience
with groundwater hydrology, opined the proposed Physical Solution would bring the
AVAA basin back into balance because of its component parts: substantial reductions in
pumping by existing users, importation of supplemental water, and the management and
monitoring provisions. Charles Binder, a civil engineer who acted as a watermaster for
another watershed, similarly testified the provisions of the judgment and proposed
Physical Solution would bring the AVAA basin back into hydrologic balance. Two other
experts opined the parties who received production rights under the Physical Solution
were devoting the water they extracted to reasonable and beneficial uses.
       Phelan presented no affirmative evidence during the Phase 6 trial. Phelan’s Phase
6 trial brief did assert that, based on the evidentiary record, the court should make
numerous modifications to the proposed Physical Solution. Specifically, it argued it
should be allowed to pump up to 1,200 afy without the replenishment assessment
contemplated by the Physical Solution or, alternatively, to pump 700 afy without a
replenishment assessment, based on its historical pumping from all its wells (including its
wells outside the AVAA boundaries) within the Buttes subbasin and the impacts of its
pumping upon water levels within that subunit.13 It also asserted the judgment should
recognize appropriative pumping rights held by Phelan were entitled to be accorded
municipal priority under sections 106 and 106.5 of the California Water Code.14

levels in the areas encompassed by the AVAA (as well as attendant subsidence problems) were
well known for decades.
       13Phelan’s   Phase 6 trial brief also opposed certain language within the proposed Physical
Solution, including characterizing Phelan as an “exporter” of water, and to the ambiguity created
by certain “costs” language contained in paragraph 6.4.1.2 of the Physical Solution.
       14Phelan  apparently presented no evidence in support of its claim there was an
unreasonable use of water by other cross-defendants and, while Phelan interposed objections to
the proposed statement of decision, its objections contained no mention of this claim.

                                               15.
       The court’s Phase 6 proposed statement of decision concluded, as to Phelan’s
remaining claims, that Phelan lacked an appropriative right to draw water from the
AVAA because the longstanding overdraft conditions in the AVAA basin as a whole
meant there was no surplus water available for Phelan to acquire or enlarge an
appropriative water right. It further rejected Phelan’s return flow claims because such a
claim is limited to return flow from imported water, and Phelan never imported water
into the AVAA.
The Final Judgment and Adoption of the Physical Solution
       The court’s final judgment, which incorporated determinations from prior phases,
found the collective demands by those holding water rights in the AVAA basin exceeded
the available total safe yield of 110,000 afy (comprising a native safe yield of 82,300 afy
and the balance coming from imported supplemental water supplies) for the entire basin,
and that a comprehensive adjudication of all of the water rights within the AVAA basin
and a water resource management plan was required to prevent further depletion of and
damage to the AVAA basin. The court found (1) the United States had produced
substantial evidence establishing a federal reserved water right, (2) the PWS had
produced substantial evidence showing they had acquired a prescriptive right as against
certain parties who had not joined in the stipulated judgment, and (3) Phelan had not
shown it had acquired an appropriative water right (or any other right) in the AVAA
basin’s safe yield. Specifically, the court noted that, while Phelan was an overlying
landowner in the AVAA basin by virtue of its ownership of the parcel on which it
operated Well 14, the water it drew from that parcel was not used for that parcel but was
instead used to service its customers outside the AVAA. Its final judgment approved
Phelan’s ability, as granted by the approved Physical Solution, to pump up to 1,200 afy
subject to the payment of a replacement assessment, and found Phelan had no right to
pump water from the AVAA except under the terms of that Physical Solution.

                                            16.
       The court further found that the stipulating “Landowner Parties” and “Public
Overliers” had established they possessed overlying rights to the basin’s native safe
yields by producing evidence of the amounts of the basin groundwater they actually used,
that such amounts were reasonable and beneficial uses of such water, and that the total
amounts so used exceeded the total native safe yield.15 The court also granted final
approval to a settlement for the “Small Pumper Class,” which allocated certain
production rights to members of that class.
       The court found that, because the native safe yield was well below the amounts
used for reasonable and beneficial purposes by those with overlying, prescriptive, or
reserved rights, it was necessary to allocate the native safe yield among these rights
holders to protect the AVAA basin for existing and future users. The court concluded the
evidence presented during Phases 4 and 6 supported the conclusion that the Physical
Solution, which required these rights holders to severely reduce the amount of water they
used and created an overarching water management plan for the AVAA basin, fairly
allocated the available water supplies and made the maximum reasonable and beneficial
use of the native safe yield in a manner which would protect the AVAA basin for existing
and future users while preserving the ability of existing rights holders to continue using
the available water.

       15The court    made similar findings as to a group of nonstipulating landowner parties who
claimed overlying rights in the basin’s groundwater by proof of their land ownership or other
interest in the basin. While this group was not signatories to the original settlement, they
supported the proposed judgment and Physical Solution and agreed to reduce production under
paragraph 5.1.10 of the Physical Solution to certain specified amounts. The court found these
parties had shown they had an overlying right to basin water, that they had reasonably and
beneficially used basin water, and that the amounts they were allocated under the Physical
Solution was a severe reduction of their historical and current uses and represented amounts they
applied to reasonable and beneficial uses.

                                               17.
                                        DISCUSSION
I.     Substantial Evidence Supports the Conclusion the Physical Solution Will
       Bring the AVAA Basin Into Balance*
       A court may impose a physical solution to protect an aquifer from the deleterious
effects of overdrafting the aquifer. (City of Santa Maria v. Adam (2012) 211 Cal.App.4th
266, 288.) “A physical solution is an equitable remedy designed to alleviate overdrafts
and the consequential depletion of water resources in a particular area, consistent with the
constitutional mandate to prevent waste and unreasonable water use and to maximize the
beneficial use of this state’s limited resource.” (California American Water v. City of
Seaside (2010) 183 Cal.App.4th 471, 480.) A court’s physical solution can reasonably
regulate the use of the water by the respective rights-holders provided its provisions are
“adequate to protect the one having the paramount right in the substantial enjoyment
thereof and to prevent its ultimate destruction ….” (Peabody v. City of Vallejo (1935) 2
Cal.2d 351, 383 (Peabody).) A physical solution must consider the rights and priorities
of the vested rights holders in light of the constitutional principle requiring that available
water be put to beneficial use to the fullest extent possible. (City of Barstow v. Mojave
Water Agency (2000) 23 Cal.4th 1224, 1250 [“although it is clear that a trial court may
impose a physical solution to achieve a practical allocation of water to competing
interests, the solution’s general purpose cannot simply ignore the priority rights of the
parties asserting them. [Citation.] In ordering a physical solution, therefore, a court may
neither change priorities among the water rights holders nor eliminate vested rights in
applying the solution without first considering them in relation to the reasonable use
doctrine”].)
       Phelan argues on appeal there is no substantial evidence to support the trial court’s
finding that the adopted Physical Solution would bring the AVAA into hydrological

       *See footnote, ante,   page 1.

                                             18.
balance and thereby “prevent its ultimate destruction.” (Peabody, supra, 2 Cal.2d at p.
383.)

        “Where findings of fact are challenged on a civil appeal, we are bound by
        the ‘elementary, but often overlooked principle of law, that … the power of
        an appellate court begins and ends with a determination as to whether there
        is any substantial evidence, contradicted or uncontradicted,’ to support the
        findings below. (Crawford v. Southern Pacific Co. (1935) 3 Cal.2d 427,
        429.) We must therefore view the evidence in the light most favorable to
        the prevailing party, giving it the benefit of every reasonable inference and
        resolving all conflicts in its favor in accordance with the standard of review
        so long adhered to by this court.” (Jessup Farms v. Baldwin (1983) 33
        Cal.3d 639, 660.)
The testimony of a single witness, unless it is impossible or inherently improbable, will
be sufficient to support the challenged findings. (Sonic Manufacturing Technologies, Inc.
v. AAE Systems, Inc. (2011) 196 Cal.App.4th 456, 465–466.) When a party asserts on
appeal that a judgment lacks substantial evidentiary support, it is that party’s burden to
summarize the evidence on that point—both favorable and unfavorable—and then to
demonstrate how and why it is insufficient. (Huong Que, Inc. v. Luu (2007) 150
Cal.App.4th 400, 409.)
        Phelan’s insufficient evidence claim rests principally on the contention the
testimony of two experts, which was offered by the proponents of the Physical Solution
in Phase 6 of the underlying trial, does not provide sufficient evidence the Physical
Solution would bring the AVAA into balance. The first expert, Mr. Binder, had
extensive training and experience in water resource management and who (among other
qualifications) served as the watermaster and the watermaster engineer to administer and
enforce a similar physical solution for the Santa Margarita Watershed. Binder premised
his opinion on a review of the terms of the proposed Physical Solution, the technical
reports from a variety of agencies, and the court’s orders and decisions in the prior phases
of the AVGC litigation. Based on his review of all these materials, Mr. Binder opined (1)
the Physical Solution would result in reduced groundwater production to a level equal to

                                             19.
the amount of the safe yield resulting in the basin being stabilized into hydrologic
balance, (2) the native safe yield plus available supplemental water supplies would be
sufficient to meet total current water requirements under the allocations contemplated in
the Physical Solution, and (3) the proposed judgment and Physical Solution would create
a functional structure for administering the judgment and managing the groundwater
basin. Binder noted the management structure included a watermaster and watermaster
engineer to manage the groundwater basin, a financial plan to fund the management
structure, flexible management tools to manage the basin, and retention of court
jurisdiction to enforce or modify the judgment.
       Dr. Williams, an expert geologist, hydrogeologist and groundwater hydrologist,
and an expert on groundwater modeling and management, also concluded the proposed
Physical Solution would bring the AVAA basin into hydrologic balance. Dr. Williams
formed his opinion using a computer model created by the United States Geological
Survey, known as a “distributed parameters” model, which he used to assess the impacts
of pumping and recharging within the mapped area.16 Dr. Williams used the model to
project the impacts on the AVAA’s hydrologic balance over the next 50-year period
using multiple different scenarios. His first two scenarios (scenarios 1 and 1A) modeled
and evaluated the long-term impacts on the AVAA basin without reduced pumping by

       16Williams    explained that, before the “distributed parameters” computer model was
available, hydrologists used a “lumped parameter” model that treated the entire basin as a giant
bathtub in which total inflows and outflows were used to assess storage changes. In contrast, the
distributed parameters model creates a fine mesh (comprising over 60,000 individual micro-
parcels or “cells” measuring 1,000 by 1,000 meters per cell with each cell having several vertical
layers to reflect the depths of the relevant geological features), which was overlaid on the AVAA
basin to more finely evaluate the impacts of pumping and recharge and “solve” water balances
for each of the cells. The United States Geological Survey model covered a much greater area
than the AVAA, so only the cells relevant to evaluating the proposed Physical Solution
(primarily the cells covering the alluvial sediments in the AVAA) were activated for purposes of
running the computer modeling. The model allowed Williams to input the amount of pumping
for each individual pumper (whether reduced or unreduced) and assign it to a particular “cell” of
the map where that pumper was operating the specific pump.

                                               20.
current users as contemplated by the proposed Physical Solution: scenario 1 assumed
unreduced current pumping with aquifer recharge under drought conditions (where the
rain and imported water recharging the AVAA basin was constricted), while scenario 1A
again assumed unreduced current pumping but under average conditions where rain and
imported water recharged the aquifer with the 110,000 afy of safe yield. Based on the
model, he concluded either scenario would cause adverse impacts on the AVAA basin.
       Dr. Williams then used the computer model to calculate the projected long-term
impacts on the AVAA basin if the reduced pumping (and other measures) contemplated
by the proposed Physical Solution were adopted using two more scenarios (scenarios 2
and 2A), again using parallel aquifer recharge assumptions under drought conditions
(scenario 2) and under average recharge conditions (scenario 2A). Dr. Williams
concluded that implementing the terms of the Physical Solution, in which existing rights
holders reduced their pumping over a specified period, would stabilize the AVAA’s
hydrological balance under either scenario 2 or 2A.
       Dr. Williams subsequently ran a computer modeling (which he denominated as
scenario 2B) to simulate the impact on the AVAA of Phelan’s pumping from Well 14 of
1,200 afy under the average recharge conditions employed in scenario 2A. He concluded
such pumping from Phelan’s Well 14 would cause the AVAA to have a net loss to the
AVAA groundwater supplies of 700 afy.
       The testimony of Binder and Williams provides ample evidence to support the
finding the Physical Solution prevented the “ultimate destruction” of the AVAA basin
while providing protections for the parties with paramount rights to substantially enjoy
the available supplies in that basin. (Peabody, supra, 2 Cal.2d at p. 383.) However,
Phelan asserts Dr. Williams’s testimony must be disregarded in evaluating the evidentiary
support for that finding because the methodology employed in his computer modeling
was flawed. Specifically, Phelan asserts (1) not all of the cells in the United States
Geological Survey model within the AVAA were “activated,” (2) there were no

                                             21.
“calibration wells” in the area near Phelan’s Well 14, and (3) the modeling of the impact
of pumping from Well 14 was done by moving its location to the nearest “active” cell in
order to simulate such impacts. Accordingly, argues Phelan, Dr. Williams’s testimony
cannot provide substantial evidence for the findings the Physical Solution would stabilize
the AVAA basin and bring it into hydrologic balance because the model did not
“accurately depict the workings of the groundwater basin.” We reject Phelan’s claim that
Williams’s opinion must be disregarded in assessing whether substantial evidence
supports the trial court’s finding for two reasons. First, Phelan acknowledges its motion
to strike Williams’s testimony, which appears to have been based on essentially the same
alleged imperfections in the modeling, was denied by the trial court. Phelan makes no
effort on appeal to satisfy its burden of showing the denial of its motion to strike
Dr. Williams’s testimony was an abuse of discretion. (Sargon Enterprises, Inc. v.
University of Southern California (2012) 55 Cal.4th 747, 773 [“Except to the extent the
trial court bases its ruling on a conclusion of law (which we review de novo), we review
its ruling excluding or admitting expert testimony for abuse of discretion”].) Because we
may not interfere with the broad discretion accorded to trial courts in admitting expert
testimony absent a showing such discretion was clearly abused (People v. Bui (2001) 86
Cal.App.4th 1187, 1196), and Phelan has made no showing such discretion was clearly
abused here (cf. Shaw v. County of Santa Cruz (2008) 170 Cal.App.4th 229, 281), we
must presume the ruling on the motion to strike was properly denied and that the trial
court therefore properly admitted and considered his testimony. Second, while Phelan
makes multiple suggestions on appeal on how Williams’s computer modeling could have
been more precise or comprehensive, Phelan cites no evidence those suggested
improvements to the model (even if implemented) would have materially changed the
results reached by the model (or Dr. Williams’s opinion based thereon) that the Physical
Solution would stabilize the AVAA basin’s hydrological balance under either scenario 2

                                             22.
or 2A, or would have altered his opinion that pumping from Phelan’s Well 14 would
cause the AVAA to have a net loss to the AVAA groundwater supplies of 700 afy.
       Because Phelan has not demonstrated that admitting Dr. Williams’s testimony was
an abuse of discretion, nor does the record contain evidence that any imperfections in the
model so materially impacted his conclusions that his testimony (as admitted) should be
entirely disregarded on appeal, Dr. Williams’s opinion provides ample support for the
judgment. Other courts that have considered arguments attacking an expert’s testimony,
analogous to those mounted by Phelan here, have similarly rejected such arguments on
appeal. For example, in Corona Foothill Lemon Co. v. Lillibridge (1937) 8 Cal.2d 522,
the appellants challenged whether there was substantial evidence for the trial court’s
determinations of the boundaries of the aquifer, and supported that challenge by detailing
the evidence at trial supporting a contrary conclusion. The court, noting there was
“voluminous evidence of a highly conflicting nature [and] [w]ell qualified witnesses on
each side testified concerning the geology of the area, its hydrology, and the relative
permeability of soils in Temescal wash, on Norco mesa, and on the Corona slope” (id. at
p. 527), rejected the appellate claim. The Corona court observed the evidence created
“… substantial points of agreement and also decided points of material disagreement
[among the experts on] whether the entire Corona area constitutes a single underground
water basin or reservoir” (id. at p. 528) but rejected the appellants’ claim because, while
the appellants’ contrary claims had evidentiary support, “… there is in contradiction of
[the appellants’] evidence ample proof which, if believed by the trial court, supports its
conclusion that the underground reservoir embraces the entire Corona area.” (Ibid.;
accord, Allen v. California Water and Tel. Co. (1946) 29 Cal.2d 466, 481 [expert
testimony on absence of surplus for appropriation; court rejects substantial evidence
challenge because “the trial court’s findings have substantial evidentiary support in the
testimony of [expert] Lee and other witnesses for plaintiffs; [the appellate] attacks made
by defendant upon the testimony of Mr. Lee go only to its credibility and weight; and …

                                            23.
these are matters committed to the trier of the facts for determination in the case of an
expert as well as of lay testimony”].)
       Moreover, even assuming Phelan had adequately carried its appellate burden
demonstrating it was a clear abuse of discretion to admit Dr. Williams’s testimony, the
testimony of Mr. Binder would alone provide substantial evidentiary support for the
finding the panoply of provisions in the Physical Solution would bring the AVAA into
hydrological balance. Although Phelan attacks Binder’s opinions on appeal,17 Phelan did
not move to strike Binder’s testimony below, nor does it articulate (apart from a
peremptory allegation that his testimony must be deemed “irrelevant”) why his testimony
does not provide substantial evidence to support the trial court’s conclusion the Physical
Solution would protect the AVAA basin from further degradation. Because the
testimony of a single witness (unless it is impossible or inherently improbable) is
sufficient to support the challenged findings (Sonic Manufacturing Technologies, Inc. v.
AAE Systems, Inc., supra, 196 Cal.App.4th at pp. 465–466), and Phelan has not shown
Binder’s opinion was either impossible or inherently improbable, Binder’s opinion alone
provides substantial evidentiary support for the conclusion the Physical Solution would
bring the AVAA into hydrologic balance.
       Phelan appears to argue our ordinary assessment of whether there is any
substantial evidence to support the findings below (Crawford v. Southern Pacific Co.,
supra, 3 Cal.2d at p. 429), and which requires us to view the evidence in the light most
favorable to the judgment with every reasonable inference drawn in favor thereof (Jessup
Farms v. Baldwin, supra, 33 Cal.3d at p. 660), is inapplicable here because Phelan
contends the final statement of decision affirmatively shows the court’s determinations

       17Phelan  points out, for example, that certain numbers used in Binder’s analysis changed
between the time he gave his deposition and the time of his trial testimony, and also claims
Binder’s analysis considered nongroundwater sources in alleged contravention of a limiting
determination from the Phase 1 trial.

                                              24.
were not based on a weighing of the conflicting evidence. Specifically, Phelan argues the
final statement of decision does not catalogue each item of evidence accepted or rejected
by the court (and the rationale for each such acceptance or rejection) in reaching its final
determinations, and that this lacuna shows the court reached its determinations without
weighing the evidence. Based on this predicate—the claim the record affirmatively
shows the decision was not based on a weighing of the evidence—Phelan asserts we are
precluded from employing the deferential substantial evidence standard to review its
decision under Kemp Bros. Construction, Inc. v. Titan Electric Corp. (2007) 146
Cal.App.4th 1474 (Kemp) and Affan v. Portofino Cove Homeowners Assn. (2010) 189
Cal.App.4th 930 (Affan).
       However, Phelan’s contention that alleged deficiencies in the final statement of
decision requires application of some standard of review other than the deferential
substantial evidence standard is first raised in Phelan’s reply brief. Ordinarily, “‘[p]oints
raised for the first time in a reply brief will … not be considered, because such
consideration would deprive the respondent of an opportunity to counter the argument.’
[Citation.] … ‘“Obvious considerations of fairness in argument demand that the
appellant present all of his points in the opening brief. To withhold a point until the
closing brief would deprive the respondent of his opportunity to answer it or require the
effort and delay of an additional brief by permission. Hence the rule is that points raised
in the reply brief for the first time will not be considered, unless good reason is shown for
failure to present them before.”’ [Citation.]” (Reichardt v. Hoffman (1997) 52
Cal.App.4th 754, 764.)
       Even assuming Phelan had preserved this argument, it rests on a predicate that
misconceives what is required in a statement of decision. Phelan’s argument under Kemp
and Affan is predicated on its assertion that a statement of decision which does not
contain a detailed discussion of all of the evidence and a discussion of why the court
chose to credit some evidence while rejecting other evidence affirmatively shows the

                                             25.
court did not weigh the evidence in reaching its decision. However, a statement of
decision is required only to set out ultimate findings rather than evidentiary ones.
(Muzquiz v. City of Emeryville (2000) 79 Cal.App.4th 1106, 1125.) A trial court “‘is not
required to respond point by point to the issues posed in a request for statement of
decision. The court’s statement of decision is sufficient if it fairly discloses the court’s
determination as to the ultimate facts and material issues in the case.’ (Golden Eagle Ins.
Co. v. Foremost Ins. Co. (1993) 20 Cal.App.4th 1372, 1379–1380; [citation].) ‘When
this rule is applied, the term “ultimate fact” generally refers to a core fact, such as an
essential element of a claim.’ (Central Valley General Hospital v. Smith (2008) 162
Cal.App.4th 501, 513.) ‘Ultimate facts are distinguished from evidentiary facts and from
legal conclusions.’ (Ibid.) Thus, a court is not expected to make findings with regard to
‘detailed evidentiary facts or to make minute findings as to individual items of evidence.’
(Nunes Turfgrass, Inc. v. Vaughan-Jacklin Seed Co. (1988) 200 Cal.App.3d 1518,
1525.)” (Thompson v. Asimos (2016) 6 Cal.App.5th 970, 983.) Phelan’s argument
“would require the court to make detailed findings of evidentiary facts as to each
individual piece of evidence relied upon by the trial court. Under the law, [Phelan is] not
entitled to such a detailed analysis.” (People v. Dollar Rent-A-Car Systems, Inc. (1989)
211 Cal.App.3d 119, 128.) Here, the statement of decision fairly disclosed the court’s
determination as to the ultimate facts and material issues in dispute in each phase of the
proceedings. Accordingly, we reject Phelan’s claim the statement of decision was too
inadequate to warrant review under the substantial evidence standard.18

       18This  analysis renders moot Phelan’s reliance on Kemp and Affan. In both of those
cases, the record affirmatively showed the trial court’s judgment was based on reasons unrelated
to an assessment of the conflicting evidence. In Kemp, for example, a prime contractor sued a
subcontractor for breach of contract and sought a pretrial right to attach order against the
subcontractor’s accounts receivable, which required an affirmative showing by the prime
contractor of the “probable validity” of its breach of contract claim. The court granted the
attachment order, but the minute order and reporter’s transcripts showed the court granted the
order not because the plaintiff had affirmatively shown the probable validity of its claim, but
because it ruled the defendant was barred (by collateral estoppel principles) from contesting the

                                               26.
       Phelan’s final attack on the evidentiary support for adopting the Physical Solution
appears to argue the evidence was insufficient because there was no evidence Phelan’s
pumping “substantially harms the AVAA such that Phelan should be required to pay a
replacement assessment” for the amounts it pumps. However, there is substantial
evidence Phelan’s pumping harms the AVAA basin’s water balance. Dr. Williams
testified Phelan’s pumping diminished the AVAA water balances by 700 AF each year,
and Phelan’s own expert agreed Well 14 extracts more water from the AVAA basin than
was being returned to the AVAA basin from return flows from those extracted waters.
This final argument by Phelan appears to suggest that, as long as the negative impacts of
its pumping on the AVAA basin do not substantially harm the AVAA basin, there is no
evidence supporting the Physical Solution’s regulation of its pumping. However, Phelan
cites no authority that a court lacks evidentiary support for a Physical Solution merely
because any one party regulated thereunder can argue that exempting its pumping from
its terms would only minimally diminish the effectiveness of the Physical Solution.
(Contra, City of Lodi v. East Bay Mun. Utility Dist. (1936) 7 Cal.2d 316, 341 [trial court
has power and duty to admit evidence relating to possible physical solutions and “to
enforce such solution regardless of whether the parties agree”].) Indeed, we believe this

plaintiff’s breach of contract claim. (Kemp, supra, 146 Cal.App.4th at pp. 1476–1481.) The
appellate court, concluding the trial court erred by using collateral estoppel on the probable
validity issue, also rejected invoking substantial evidence review to affirm the determination on
the probable validity issue because it was clear the court never considered or weighed any
evidence once it determined (erroneously) collateral estoppel obviated examination of that issue.
(Id. at pp. 1477–1478.) Similarly, in Affan, supra, 189 Cal.App.4th 930, the trial court rejected
an owner’s claim of negligence against a homeowners association because it apparently
misconstrued a fact-based “judicial deference” defense (available to associations under Lamden
v. La Jolla Shores Clubdominium Homeowners Assn. (1999) 21 Cal.4th 249) as a blanket
immunity defense (Affan, supra, at pp. 938–940), and therefore never examined whether the
requisite facts had been established to invoke that judicial deference defense. (Id. at pp. 940–
944.) Unlike those cases, the statement of decision here does not show the approval of the
Physical Solution was based on matters dehors the evidence (as in Kemp) or on erroneous legal
standards (as in Affan), but was instead based on correct legal considerations and after
considering the evidence. Accordingly, neither Kemp or Affan is relevant here.

                                               27.
argument (if credited) would eviscerate the ability of a court to adopt any basin-wide
physical solution: if any single water rights holder could bar adoption of a proposed
physical solution unless it was exempted from it by asserting its specific unconstrained
pumping would have limited impact on the effectiveness of its remaining regulations, any
proposed physical solution could be exposed to a “death by a thousand cuts” because
each objecting water claimant could likewise claim exemption from its regulation under
the “individual de minimus impacts” argument.
       We conclude Phelan has not carried its appellate burden of showing there was
inadequate evidence to support the conclusion the Physical Solution adequately met the
twin goals of protecting the paramount rights of vested water rights holders while
preventing the ultimate destruction of the AVAA aquifer (Peabody, supra, 2 Cal.2d at p.
383), and we therefore reject Phelan’s first argument on appeal.
II.    The Trial Court Correctly Rejected Phelan’s Fourth Cause of Action
       Asserting It Had Acquired Water Rights as a “Public Use Appropriator”
       Phelan’s cross-complaint, in addition to asserting it had acquired protectable water
rights either as an appropriator (if surplus water existed) or by prescription (if there was
not surplus water), also asserted it had “rights to pump water from the Basin to meet its
municipal water demands … as a matter of law and public policy” under California
Water Code sections 106 and 106.5, which Phelan contended provided it with a “prior
and paramount right to Basin water as against all non-municipal uses.” The trial court’s
final statement of decision concluded Phelan had not acquired any right, whether
appropriative or otherwise, to AVAA basin groundwater. On appeal, Phelan appears to
assert the “public use” doctrine and policies embodied in Water Code sections 106 and
106.5 confer on Phelan a right—as a municipal appropriator for public use—to pump
water from the AVAA for municipal purposes regardless of whether a surplus existed
when it began pumping from Well 14.

                                             28.
       California’s “dual system of water rights”19 essentially provides two sources by
which water rights in surface waters can be acquired: by riparian rights holders who
have first priority to the available water for riparian uses, or by appropriation of water for
nonriparian uses when there is water in surplus beyond that used by first priority users.
(See generally Santa Barbara Channelkeeper v. City of San Buenaventura (2018) 19
Cal.App.5th 1176, 1183.)

       “Similar principles govern rights to water in an underground basin. First
       priority goes to the landowner whose property overlies the groundwater.
       These ‘overlying rights’ are analogous to riparian rights in that they are
       based on ownership of adjoining land, and they confer priority. [Citation.]
       Surplus groundwater also may be taken by an appropriator, and priority
       among ‘appropriative rights’ holders generally follows the familiar
       principle that ‘“the one first in time is the first in right.”’ (City of Barstow
       v. Mojave Water Agency, supra, 23 Cal.4th] at p. 1241.) With groundwater
       there is an exception, however, that gives rise to a third category of rights.
       Under certain circumstances, an appropriator may gain ‘prescriptive rights’
       by using groundwater to which it is not legally entitled in a manner that is
       ‘“actual, open and notorious, hostile and adverse to the original owner,
       continuous and uninterrupted for the statutory period of five years, and
       under claim of right.”’ (Ibid.)” (Santa Barbara Channelkeeper v. City of
       San Buenaventura, supra, at p. 1184.)
       Phelan does not assert its pumping from Well 14 is pursuant to the exercise of
rights it holds either as an overlying landowner or by prescription. Accordingly,
assuming the court correctly rejected Phelan’s claim there was surplus water upon which
Phelan could have acquired protectable rights in the final recognized category of water
rights (i.e., as an appropriator of surplus water), Phelan lacks any cognizable groundwater

       19Although courts generally refer to the “dual system” of water rights, the courts have
acknowledged that “California’s water rights system is not really dual but is instead tripartite,
because some pueblo rights superior to riparian or appropriative rights exist.” (Siskiyou County
Farm Bureau v. Department of Fish & Wildlife (2015) 237 Cal.App.4th 411, 423, fn. 3.)
Because the pueblo rights overlay is not implicated by Phelan’s appeal, we employ the “dual
system” nomenclature and principles in evaluating its appeal.

                                               29.
rights in the AVAA.20 Phelan’s “public use appropriator” argument instead posits there
is another possible source for acquiring protectable rights to groundwater: that even
without a surplus upon which Phelan could premise a claim as an appropriator, Water
Code sections 106 and 106.5 and a variety of cases have created a public-policy-based
alternative upon which Phelan could have acquired a protectible interest in the aquifer.
       We conclude neither Water Code sections 106 and 106.5 nor the cases cobbled
together by Phelan provides support for this novel theory that a pumper for municipal
purposes can tap into an overdrafted aquifer and in doing so acquire protectable water
rights in that aquifer. While the statutes cited by Phelan are declarative of general public
policy,21 Phelan has cited no case (nor have we located any) in which those sections were
employed to acquire a water right that would not otherwise have been acquired under the
laws governing acquisition of water rights by overlying, appropriative, or prescriptive
users. Instead, those sections appear to only be relevant to assigning and protecting
priorities among existing water rights holders. (See, e.g., Deetz v. Carter (1965) 232
Cal.App.2d 851 [dispute among riparian rights holders resolved with domestic user given
priority over irrigator].) Because those sections appear limited to assigning and
protecting priorities, and the same legislative enactment which created those includes the
express declaration that “[i]n the enactment of this code the Legislature does not intend
thereby to effect any change in the law relating to water rights” (Wat. Code, § 103), we
reject Phelan’s argument these sections create a special avenue by which municipal water
suppliers can acquire a correlative appropriative right in an overdrafted aquifer.

       20In the unpublished portions of this opinion, we conclude the trial court did not err when
it concluded there was no available surplus upon which Phelan could premise a claim as an
appropriator.
       21Water Code section    106 merely states that it is “the established policy of this State that
the use of water for domestic purposes is the highest use of water and that the next highest use is
for irrigation.” Section 106.5 states only that it is “the established policy of this State that the
right of a municipality to acquire and hold rights to the use of water should be protected to the
fullest extent necessary for existing and future uses.”

                                                 30.
       The cases cited by Phelan are equally inapposite to its argument. For example,
while Phelan relies heavily on Peabody, supra, 2 Cal.2d 351 for its “appropriat[ion] for
public use” argument, Peabody’s legal relevance is limited. There, the riparian owners
sued a public agency for impairing their rights to river water after the agency had
completed a dam and began impounding river water (for diversion to municipal uses),
thereby reducing the water available to the downstream riparian owners. The trial court
concluded the downstream owners were entitled to all of the waters from the stream and
enjoined the agency from impounding waters behind the dam. (Id. at pp. 358–363.) The
Peabody court merely concluded that, because the public use had commenced before the
plaintiffs commenced their action to establish their water rights, the plaintiffs could not
enjoin the agency from continuing to operate the dam, but were instead limited to other
remedies, such as recovering any appropriate damages or to a physical solution
minimizing or eliminating any damages otherwise recoverable. (Id. at pp. 377–380.) We
conclude Peabody does not hold a public agency can acquire an appropriative water right
merely by constructing and operating facilities diverting water for public use, but instead
merely delimits the remedies which might be available when such activity by the public
agency injures the rights held by paramount water rights holders.22
       The other cases relied on by Phelan are equally inapposite. (See, e.g., Tulare Dist.
v. Lindsay-Strathmore Dist. (1935) 3 Cal.2d 489, 535–538 [discussing availability of
injunctive relief against public use appropriator]; Hillside Water Co. v. City of Los
Angeles (1938) 10 Cal.2d 677, 688 [same]; Wright v. Goleta Water Dist. (1985) 174
Cal.App.3d 74, 90 [“Intervention of a public use does not bar suit by the owner of a water

       22Peabody is  also factually distinguishable. There, the agency had already completed a
dam and began impounding river water before the riparian owners filed suit to establish their
paramount water rights. (Peabody, supra, 2 Cal.2d at p. 377.) Here, while Phelan had acquired
the parcel on which it constructed Well 14 before commencement of the AVGC litigation, the
litigation commenced before it began operating its well. Thus, unlike Peabody, the public use
here did not commence until after the action to establish water rights in the AVAA was
underway.

                                              31.
right; it merely limits his remedy to damages in place of an injunction”].) Neither these
cases, nor Phelan’s remaining authorities, provides any additional support for its claim
that the municipal priority sections of the Water Code create an independent avenue for
acquiring water rights in an overdrafted aquifer.23
       We conclude neither the cited Water Code sections nor the case law supports
Phelan’s argument a public agency may acquire appropriative rights in water from an
aquifer absent a surplus in that aquifer to which appropriative rights can attach.

III.   The Phased Decisional Procedure Did Not Deprive Phelan of Due Process*
       Phelan appears to argue it was deprived of its due process rights because of the
order in which issues were resolved in the trial court’s phased proceedings. Phelan
specifically asserts the court erred when it determined (during the Phase 3 trial) the
AVAA basin was in overdraft while deferring the subsidiary determination of whether
the water use by all water users in the AVAA basin (whether overlying owners,
prescriptive rights holders, or prior appropriators) were for reasonable and beneficial
uses. This alleged error, asserts Phelan, deprived it of its due process right to show there
was surplus water upon which Phelan could premise its claim to an appropriative water
right. Phelan also appears to argue the court erroneously placed on Phelan the burden to
show there was unreasonable water uses by claimants with priority over Phelan that

       23For   example, Phelan states that “‘[p]ublic use of percolating water is a nonoverlying
use, whether the lands that receive such public service are overlying lands or whether they are
located outside of the ground-water area. Such public use is therefore an appropriative use of
the water.’” (Quoting Hutchins, The California Law of Water Rights (1956) p. 458, italics and
boldface supplied by Phelan.) While this accurately describes what is an “appropriative use,” it
is an excerpt taken from Hutchins’s overall discussion on the “Appropriation of Surplus
Percolating Waters,” which cautions that “[i]t is surplus or excess waters above the quantities to
which the paramount rights of the overlying owners attach that are subject to appropriation for
nonoverlying uses.” (Id. at p. 454.) Thus, Hutchins’s description of one type of appropriative
use (public use outside the groundwater area) does not obviate the predicate for acquiring
protectable appropriative user rights: the existence of surplus water above that water which is
subject to paramount rights holders.
       *See footnote, ante,   page 1.

                                               32.
might have (if eliminated) provided surplus water available for appropriation by Phelan.
Before we can evaluate Phelan’s claims of procedural error, we must outline the
substantive law the trial court was required to apply in the proceedings below.
       A.      General Principles: Overlying/Appropriative/Prescriptive Rights, the
               Significance of “Surplus” and the “Reasonable and Beneficial Use”
               Limitations on Water Use
       As previously discussed, California’s “dual system of water rights” in water
courses contemplates two sources by which water rights can be acquired: by riparian
rights (water rights held by virtue of owning land adjacent to or through which flowing
water passes to use the water for such owned lands) or by appropriative rights (water
rights held from diverting and using such water for the benefit of noncontiguous lands).
(Light v. State Water Resources Control Bd. (2014) 226 Cal.App.4th 1463, 1477–1478.)
As between riparian rights holders and appropriative rights holders, the former group has
paramount priority to the available water in times of shortages. (Id. at p. 1478.)
       Analogous principles apply to water from aquifers: rights can be held by an
overlying landowner (who has paramount priority to use the water to benefit the owned
land analogous to a riparian owner) or by an appropriator if there is surplus water above
the needs of paramount claimants. (See generally Santa Barbara Channelkeeper v. City
of San Buenaventura, supra, 19 Cal.App.5th at pp. 1183–1184.) In the case of aquifers,
however, there is an exception giving rise to a possible third category of rights: an
appropriator may (under certain circumstances) gain “prescriptive rights” by using
groundwater to which it was not legally entitled if the ordinary elements of prescription
are satisfied. (Ibid.)
       The key issue in deciding whether a party has acquired a protectable appropriative
right is the existence of a “surplus,” i.e., whether there was water beyond the amounts
needed by paramount rights holders. (City of Barstow v. Mojave Water Agency, supra,
23 Cal.4th at pp. 1240–1242 [“‘Any water not needed for the reasonable beneficial use of

                                            33.
those having prior rights is excess or surplus water and may rightly be appropriated on
privately owned land for non-overlying use, such as devotion to public use or exportation
beyond the basin or watershed’”].) The converse concept is overdraft: when the
withdrawals from the aquifer exceed the available recharge, there is no surplus but there
is instead overdraft. (City of Los Angeles v. City of San Fernando, supra, 14 Cal.3d at
pp. 277–278, disapproved on other grounds in City of Barstow, supra, at p. 1248
[“Overdraft commences whenever extractions increase, or the withdrawable maximum
decreases, or both, to the point where the surplus ends. Thus, on the commencement of
overdraft there is no surplus available for the acquisition or enlargement of appropriative
rights. Instead, appropriations of water in excess of surplus then invade senior basin
rights”].)
       An overlay to this dual system for defining water rights is a key limiting principle:
the rule of reasonableness. (Santa Barbara Channelkeeper v. City of San Buenaventura,
supra, 19 Cal.App.5th at p. 1184.) There is an “overriding constitutional limitation that
the water be used as reasonably required for the beneficial use to be served.” (United
States v. State Water Resources Control Bd. (1986) 182 Cal.App.3d 82, 105.) The rule of
reasonableness means that paramount rights holders, while entitled to priority for water
devoted to their reasonable and beneficial uses, may not be so profligate with their uses
of available water that they deprive others of water that would otherwise be “surplus” and
hence available for appropriation. As articulated by City of Pasadena v. City of
Alhambra (1949) 33 Cal.2d 908:

       “[I]t is now clear that an overlying owner or any other person having a legal
       right to surface or ground water may take only such amount as he
       reasonably needs for beneficial purposes. [Citations.] Public interest
       requires that there be the greatest number of beneficial uses which the
       supply can yield, and water may be appropriated for beneficial uses subject
       to the rights of those who have a lawful priority. [Citation.] Any water not
       needed for the reasonable beneficial uses of those having prior rights is
       excess or surplus water …, [which] water may rightfully be appropriated

                                            34.
       on privately owned land for nonoverlying uses, such as devotion to a public
       use or exportation beyond the basin or watershed.” (Id. at pp. 925–926,
       italics added.)
       B.     Analysis
       Phelan’s due process claim on appeal, while imprecise, appears to have two
embedded claims of prejudicial error. First, Phelan argues it was error to determine
during the Phase 3 proceedings that the AVAA basin was in overdraft based on a
comparison of current extractions against the average safe yield, while bifurcating and
deferring to later stages whether the current extractions by all other water users in the
AVAA basin qualified as reasonable and beneficial uses for such extracted water.
Second, Phelan appears to argue the trial court’s delimitation of the issues determined in
Phase 3 somehow foreclosed Phelan from proving its claim that there was (or could have
been) a surplus which Phelan could pump as an appropriator, and erroneously placed on
Phelan the burden of showing there was a surplus available for appropriation by Phelan.
       A trial court has discretion to determine the order in which claims or issues are
bifurcated and determined, and the selection and scheduling of those phased
determinations will not be disturbed absent an abuse of that discretion. (See generally
Orange County Water Dist. v. Alcoa Global Fasteners, Inc. (2017) 12 Cal.App.5th 252,
353; Hoopes v. Dolan (2008) 168 Cal.App.4th 146, 163.) The issue bifurcated and
resolved in Phase 3 was a core issue common to all of the various actions—whether the
AVAA basin was currently in a state of overdraft based on current extractions in light of
the safe yield of the aquifer such that judicial intervention was required to provide for
managing the aquifer and protecting it against further degradation. We cannot conclude
that selecting this core issue for resolution at this earlier stage—whether the AVAA basin
was in overdraft—was an abuse of discretion.
       Indeed, Phelan does not contend on appeal that selecting “overdraft” as the issue
to be examined in Phase 3 was an abuse of discretion. Instead, Phelan appears to assert
the court should have employed a different metric for the Phase 3 “overdraft”

                                             35.
determination. Rather than comparing safe yield to current actual extractions from the
AVAA basin, Phelan argues the court should instead also have made the separate
determination as part of the Phase 3 trial on whether these actual extractions exceeded
withdrawals devoted to reasonable and beneficial uses. Phelan contends on appeal that
only after the court decided whether “all pumpers [from the AVAA] were pumping for
reasonable and beneficial uses” could it then decide whether such pumped amounts were
above the safe yield (overdraft) or below the safe yield (surplus). Phelan therefore argues
it was an abuse of discretion to defer examining the separate issue of whether current
actual extractions exceeded the amounts reasonably and beneficially used by the
paramount rights holders.
       However, there is no indication Phelan timely objected to the issues as delimited
for the Phase 3 trial.24 Prior to the Phase 3 trial, the court (in connection with its order
consolidating all pending actions concerning water claims to the AVAA basin,) ordered a
case management conference to hear argument concerning the sequencing of common
issues to be heard at the next phase, and proposed the issues for the Phase 3 trial would
be limited to “safe yield” and “overdraft” while numerous other issues (including
“reasonable and beneficial use of water”) would be deferred for later determination.
Phelan apparently concurred with the proposal that Phase 3 be focused on “a
determination of Basin characteristics including its safe yield and overdraft (past or
present),” and there is no suggestion Phelan objected to deferring numerous other
questions—including questions about reasonable and beneficial use—to subsequent

       24Although    Phelan’s reply brief on appeal asserts it did lodge an objection, Phelan’s
citations to the record rely solely on its objections to the proposed statement of decision
following trial of Phelan’s second and sixth causes of action, which resolved Phelan’s claims for
appropriative and return flow rights long after Phase 3 had been concluded. Phelan interposed
no timely objection, prior to the Phase 3 trial, that the issues of safe yield and overdraft
necessarily required a concurrent determination during that phase of whether the water being
extracted was being devoted to reasonable and beneficial uses.

                                               36.
phases.25 Indeed, rather than objecting or contending there might be evidence showing
the AVAA was not in overdraft, Phelan’s trial brief for Phase 3 seemed affirmatively to
assert the subbasin most relevant to Phelan (i.e., the Butte subbasin in the southeast
portion of the AVAA where Well 14 was operating) was “in overdraft or trending toward
overdraft.”26 Finally, the record is devoid of any suggestion Phelan sought to proffer
evidence, during this (or any other) phase, that actual extractions exceeded reasonable
and beneficial uses.27 Because there is no indication Phelan timely objected to the issues
as delimited for the Phase 3 trial, it may not argue for the first time on appeal that the
discretionary determination on the scope of issues to be resolved in Phase 3 was an abuse
of the trial court’s discretion. (See generally In re Kevin S. (1996) 41 Cal.App.4th 882,
885–886; Consolidated World Investments, Inc. v. Lido Preferred Ltd. (1992) 9
Cal.App.4th 373, 382.)

       25The court,   after several case management hearings, eventually ordered the Phase 3 trial
would examine whether the basin was in overdraft and specified it “does [not] expect to hear
evidence of individual pumping of water by any party within the basin; rather, it expects to hear
evidence concerning total pumping and total recharge from all sources.” That same order
advised that “[a]ny party requiring further clarification of the issues in this third phase of trial is
invited to request such clarification.” Phelan cites nothing suggesting it objected, sought
clarification, or otherwise sought to inject the “reasonable and beneficial use” issue into Phase 3.
       26Phelan’s   Phase 3 trial brief stated it would “offer evidence that pumping from
[Phelan’s] six wells located within the Groundwater Basin intercepts groundwater that would
otherwise flow to the northwest and into a portion of the Adjudication Area where irrigation
pumping by others is occurring. The evidence indicates, among other things, that the
combination of [Phelan’s] pumping and downgradient pumping by others has resulted in
declining groundwater levels in the Southeast portion of the Adjudication Area, particularly over
the past ten years. Groundwater level trends indicate that overdraft exists in the Southeast area
of the Adjudication Area, or will exist in the near future, if groundwater pumping in this area
continues at current rates or increases.”
       27Although    Phelan did submit a case management statement seeking to clarify whether
the issues to be decided in Phase 3 would necessitate testimony from their expert (Harder), none
of the subjects on which Harder was proffered purported to address reasonable and beneficial
uses of water by other AVAA users.

                                                  37.
       Phelan also appears to complain it was prejudiced because the Phase 4 trial order
originally contemplated, but ultimately omitted, consideration of the “reasonable and
beneficial use” question.28 While Phelan correctly recites the evolution of the Phase 4
“trial issues” order, Phelan cites nothing to indicate it objected to this delimitation of the
Phase 4 issues, even though it participated in the lengthy hearing at which the proposed
modification was considered and ultimately approved. Accordingly, we must deem any
claim of error to be waived. (In re Kevin S., supra, 41 Cal.App.4th at pp. 885–886.)
       Moreover, even assuming Phelan could assert it was error to exclude “reasonable
and beneficial uses” from the Phase 4 trial, Phelan has not demonstrated such error would
constitute reversible error. While the Phase 4 trial ultimately was limited to quantifying
the amounts pumped during the relevant period by the numerous parties (other than the
Small Pumper Class and Granite Construction) who claimed pumping rights in the
AVAA aquifer, Phelan does not articulate on appeal how deferring the “reasonableness
of use” question foreclosed Phelan from subsequently demonstrating the existence of
waste (as alleged in its seventh cause of action) or the existence of a basin-wide surplus
necessary to its second cause of action. Phelan does complain on appeal that its seventh
cause of action for “waste, unreasonable use or an unreasonable method of diversion or
use” was “never heard,” but Phelan does not explain how the delineation of issues in
Phases 3 or 4 precluded Phelan from litigating its seventh cause of action. To the

       28The Phase 4   trial order originally described its scope to include determining the
“reasonable and beneficial use of water for each parcel to be adjudicated.” However, a
subsequent proposal was submitted by counsel for the Wood class, and joined by other parties, to
winnow the issues to be tried in Phase 4 and limit it to identifying the actual amounts extracted
by each claimant (for the relevant years) along with the actual use to which the water was put,
while excluding from Phase 4 any litigation over whether such actual use was reasonable as to
either the type or manner of use. After extensive discussion among the parties, the Phase 4 order
was amended to clarify that the trial would be limited to “the amount of water used by each party
and the identification of the beneficial use to which that amount was applied, but will not include
any determination as to the reasonableness of that type of use, of the manner in which the party
applied water to that use, or any determination of a water right.”

                                               38.
contrary, the record shows (after the Phase 3 and 4 proceedings had been concluded) the
court held a lengthy hearing to determine which of Phelan’s claims should next be
scheduled for trial, and ultimately set the Stage One trial to encompass litigation of
Phelan’s claimed “right to pump water as an appropriator of right, Number one; and
Number two, [to] brief and present evidence … concerning [Phelan’s] right … as a public
producer apart from whether there was a surplus.” (Some capitalization omitted.) Phelan
was provided adequate opportunity to litigate whether there was available surplus in the
AVAA aquifer to support its claim as an appropriator, which could have included the
subsidiary issue it now asserts it was foreclosed from litigating: whether elimination of
unreasonable or nonbeneficial water uses would have produced a surplus (from the native
safe yield) that Phelan could have claimed as an “appropriator.” However, Phelan did not
introduce any evidence the actual amounts pumped by other users exceeded the amounts
reasonably appropriate for the beneficial purposes of those users, much less that such
wasteful uses were (in the aggregate) so enormous that eliminating such waste would
have reduced reasonable and beneficial uses to below the native safe yield and created a
surplus available for appropriation by Phelan. We conclude Phelan was not deprived of
the due process opportunity to show unreasonable or nonbeneficial uses.29

       29It  also appears Phelan could have resurrected and litigated its seventh cause of action
on two other occasions. First, after the court ruled on Phelan’s causes of action alleging it held
water rights as an appropriator of a surplus or as a municipal-uses appropriator, the court held the
August 2015 Stage 2 trial for Phelan to present evidence on its “remaining causes of action.”
Phelan’s trial brief for that Stage 2 trial addressed only its third cause of action (for a physical
solution), its claim it should have municipal appropriator status, and its eighth cause of action
seeking declaratory relief as to the “Antelope Valley Groundwater Basin.” Additionally, its
evidentiary presentation at that hearing proffered no evidence of “waste.” Phelan’s trial brief for
the August 2015 Stage 2 trial did “reserve[] the right to present evidence on its Seventh Cause of
Action,” which it suggested would be presented during the “prove up hearings” on the Physical
Solution scheduled for later that year. While these “prove-up” hearings in Phase 6 provided yet
another opportunity for Phelan to introduce evidence supporting its claim of unreasonable use of
water, Phelan ultimately disclaimed any effort to present affirmative evidence at the final phase
examining the proposed Physical Solution.

                                                39.
       The final aspect of Phelan’s claim it was denied due process appears to assert the
court misallocated the burden of proof by placing the burden on Phelan to show a surplus
existed in the AVAA basin. Phelan sub silencio argues that, under Peabody, supra, 2
Cal.2d 351, the burden should instead have been on all parties to show the amounts
actually pumped by each of the competing priority pumpers was devoted solely to
reasonable and beneficial uses, and that the absence of such evidence left the issue of
surplus unresolved.30 Cross-defendants contend the trial court correctly ruled that
Phelan, as the party asserting there was a surplus available for appropriation (necessary to
its second cause of action) or there was “waste” (as asserted in Phelan’s seventh cause of
action), had the burden to show the amounts actually pumped exceeded the amounts
devoted to reasonable and beneficial uses by the paramount rights holders.
       We conclude the trial court correctly held Phelan had the burden of proof to show
surplus and, to the extent Phelan contended that eliminating wasteful uses would reveal a
surplus existed that would be available for appropriative uses by Phelan, to show the fact
and extent of such alleged unreasonable or nonbeneficial use. Several cases support

       30Phelan    also claims the statement of decision from the Stage One trial, which rejected
Phelan’s “surplus” claim, was “flawed” because it “does not explain” why (under Peabody) the
burden of proof was not placed on all parties to first establish their actual water use was also
“reasonable and beneficial.” Phelan did assert the statement of decision required such
explanation, but the court’s final statement of decision from Stage One addressing Phelan’s
claim for surplus did explain why it concluded Phelan had the burden of proof as to surplus.
Moreover, we reject Phelan’s claim that the issue of “reasonable and beneficial use” was never
resolved below. While the Stage One statement of decision stated the court had not yet made
(but would ultimately make) a determination whether other paramount rights holders devoted the
water to reasonable and beneficial uses, it ultimately did resolve that question. The trial on the
proposed Physical Solution contemplated that it would encompass evidence that the actual uses
by the various pumpers were reasonable and beneficial uses, and evidence on this issue was
introduced by proponents of the Physical Solution. Finally, the issue was addressed and resolved
in the final statement of decision following Phase 6, when the court stated that “[b]ased on their
credible and undisputed expert witness testimony, and substantial evidence in the fourth and
sixth phases of trial, the Court finds that each stipulating Landowner Party and each Public
Overlier has reasonably and beneficially used amounts of water which collectively exceeded the
total native safe yield.”

                                               40.
placing the burden of proof on Phelan, as the party asserting an appropriative right, to
prove a surplus existed upon which it could predicate its claimed appropriative right.
(Allen v. California Water & Tel. Co., supra, 29 Cal.2d at p. 481 [“It is true that the
burden of proving the existence of a surplus is on” the party asserting the appropriative
right against overlying owners]; cf. City of Lodi v. East Bay Mun. Utility Dist., supra, 7
Cal.2d at p. 339 [in dispute between later appropriator against prior appropriator, burden
on former to prove surplus]; Monolith Portland Cement Co. v. Mojave Public Utilities
Dist. (1957) 154 Cal.App.2d 487, 494 [dicta].) This allocation of the burden of proof is
consonant with the general rule that a plaintiff has the burden of production and
persuasion to support the allegations of its claims for relief. (See generally Roddenberry
v. Roddenberry (1996) 44 Cal.App.4th 634, 652.)
       Phelan’s reliance on Peabody does not alter our conclusion the trial court correctly
assigned to Phelan the burden of showing surplus and, as a predicate to establishing such
a surplus existed, that there was waste. In Peabody, the trial court had entered a
judgment in favor of the riparian owners and against the later appropriator on the theory
that riparian owners were entitled to “all of the waters of the stream as the same were
wont to flow in the course of nature, including the flood and freshet flows thereof,
regardless of any waste or surplus that might result from the exercise of such a right and
regardless of any rule of reasonable use.” (Peabody, supra, 2 Cal.2d at p. 363.) The trial
court in Peabody had not considered the impact of the then-recent amendment of the
California Constitution, which added section 3 to article XIV, declaring “[t]he right to
water or to the use or flow of water in or from any natural stream or watercourse in this
State is and shall be limited to such water as shall be reasonably required for the
beneficial use to be served, and such right does not and shall not extend to the waste or
unreasonable use or unreasonable method of use or unreasonable method of diversion of
water.” (Peabody, at p. 366.) The Peabody court reversed and remanded the judgment
for reconsideration in light of those limitations, noting the issue is whether “after

                                             41.
excluding all of the reasonable beneficial uses present and prospective (considering in
connection therewith reasonable methods of use and reasonable methods of diversion) to
which the waters of the stream are put, either under the riparian right or by prior
appropriation, is there then water wasted or unused or not put to any beneficial use? If
so, the supply or product of the stream may be said to be ample for all, a surplus or
excess exists, … and the appropriator may take the surplus or excess without
compensation.” (Id. at pp. 368–369.) However, Peabody specifically considered
whether the burden of proof should be on the riparian owner to show its riparian rights
were injured by the appropriator’s diversion, or should instead be on the appropriator to
show “‘that there is a surplus … upon the ground that such [appropriated] waters were
waste or lost waters’” as had been held in Miller v. Bay Cities Water Co. (1910) 157 Cal.
256, 272. (Peabody, supra, at p. 381.) Peabody concluded “[t]he general rule in this
state as to the burden of proof is laid down in [former] section 1981 of the Code of Civil
Procedure as follows: ‘The party holding the affirmative of the issue must produce the
evidence to prove it; therefore, the burden of proof lies on the party who would be
defeated if no evidence was given on either side.’ However, when one enters a field of
water supply and seeks by appropriation to take water from such supply on the claim that
there is more than sufficient for all reasonable beneficial uses by those who have the prior
and preferential right, it would seem to comport with the principles of fairness and justice
that the appropriator, in whatever way the issue may arise, should have the burden of
proving that such excess exists. We therefore reaffirm the rule to that effect in the Miller
case.” (Ibid.)
       Thus, while Peabody and its progeny make clear that determining surplus can
include consideration of whether the actual amounts used by paramount water rights
holders are being applied to reasonable and beneficial uses, Peabody also casts upon the
person claiming appropriative rights the burden of showing there is available surplus after
accounting for reasonably and beneficially applied water by paramount rights holders.

                                             42.
When a showing of available surplus necessarily encompasses showing actual uses by
paramount rights holders are unreasonable (as to either the type or manner of use), as
well as quantifying such unreasonable uses in an amount necessary to provide for the
surplus claimed by the appropriator, we conclude the burden of proof is upon the
appropriator under Peabody.
       We conclude Phelan was provided adequate opportunity to proffer evidence in
support of its claim to water rights in the AVAA basin, that the trial court correctly
placed on Phelan the burden of proving its claims, and that the phased proceedings did
not impair Phelan’s opportunity to present its case. We therefore reject Phelan’s claim it
was denied due process.
IV.    The Trial Court Correctly Concluded Phelan Had No Priority Claim to
       Return Flows from Native Safe Yield*
       Phelan finally asserts that, to the extent native water was extracted from the
AVAA basin by Well 14 and then used by Phelan’s customers on land overlying the
AVGB, Phelan was entitled to any return flows from such water, and therefore it was
error to require Phelan to pay a replenishment assessment without accounting for such
return flows. Phelan, relying on Montana v. Wyoming (2011) 563 U.S. 368 and various
other foreign authorities discussing water law concepts of recapture of waste and seepage
water, asserts the trial court erred in limiting claims for return flows to importers of
nonnative waters. Cross-defendants argue the trial court below correctly held state law is
dispositive and, under cases such as City of Los Angeles v. City of San Fernando, supra,
14 Cal.3d 199 (San Fernando), the interests recognized in return flows by California
courts is limited to return flows from water imported by the claimant. Cross-defendants

       *See footnote, ante,   page 1.

                                             43.
argue that, because Well 14 only draws native water from the AVAA aquifer, the trial
court correctly rejected Phelan’s claim to return flows for water drawn from Well 14.31
       California courts, when addressing the allocation of a limited supply of
groundwater among competing claimants, have distinguished at least three sources of
such water: (1) native groundwater (rainfall, infiltration from lakes and streams, and
other natural inflows that percolate into the aquifer), (2) imported water and the return
flows it generates (imported water that is used on the surface which then percolates into
the aquifer), and (3) salvaged water (water that would have wasted to the sea during the
rainy season but for the dams and reservoirs capturing and saving it from loss to the sea)
and the return flows generated by its capture and use. (See generally City of Santa Maria
v. Adam, supra, 211 Cal.App.4th at p. 280.) The courts have concluded that, when a
party imports water into a basin that would otherwise not be available to that basin (i.e.,
not attributable to native sources of recharge), that party (after applying the water in the
first instance) also has “the prior right to quantities of groundwater attributable to return
flows of imported water.” (Id. at p. 301.) This is a rule of priorities and “means that one
who brings water into a watershed may retain a prior right to it even after it is used.
[Citation.] The practical reason for the rule is that the importer should be credited with

       31Although    we will conclude the trial court correctly rejected Phelan’s claims to return
flows from native water, nothing in this opinion should be construed to foreclose Phelan from
seeking relief under the terms of the judgment to the extent Phelan has become a de facto
importer of water. Under paragraph 6.4.1.2 of the Physical Solution, Phelan must pay a
“Replacement Water Assessment pursuant to Paragraph 9.2” for water it pumps from Well 14.
This Replacement Water Assessment is apparently designed to cover the watermaster’s costs for
“replacement waters” and specifies it “shall be used [by the watermaster] to acquire Imported
Water.” (Physical Solution, ¶ 9.2, italics added.) Phelan was not party to the provisions of the
Physical Solution (which delimited which persons or entities would be entitled to claim the
benefits of “return flows”) nor was it party to any other agreement which might exclude water
purchased by the watermaster with replacement assessments from qualifying as “imported
water.” We express no views on whether Phelan has become, albeit involuntarily, a participant
in a consortium of parties paying the watermaster to import water into the AVAA or whether
such status entitles Phelan to claim return flow interests under the rationale of San Fernando.

                                               44.
the ‘fruits … of his endeavors in bringing into the basin water that would not otherwise
be there.’” (Ibid.)
       This “fruits-of-his-endeavors” rationale has an important corollary: priority is not
given to return flows from native waters. In San Fernando, our Supreme Court rejected
such a claim, explaining:

       “Defendants contend that if any party is given rights to a return flow
       derived from delivered imported water, it is ‘obvious’ and ‘axiomatic’ that
       the same rights should be given to the return flow from delivered water
       derived from all other sources, including native water extracted from local
       wells. This argument misconceives the reason for the prior right to return
       flow from imports. Even though all deliveries produce a return flow, only
       deliveries derived from imported water add to the ground supply. The
       purpose of giving the right to recapture returns from delivered imported
       water priority over overlying rights and rights based on appropriations of
       the native ground supply is to credit the importer with the fruits of his
       expenditures and endeavors in bringing into the basin water that would not
       otherwise be there. Returns from deliveries of extracted native water do
       not add to the ground supply but only lessen the diminution occasioned by
       the extractions.” (San Fernando, supra, 14 Cal.3d at p. 261, 2d & 3d italics
       added.)
       We agree with cross-defendants the trial court correctly ruled California does not
grant an appropriator of native water any priority interest in return flows. In addition, the
authorities relied on by Phelan do not convince us that San Fernando has been overruled
sub silencio. For example, in Montana v. Wyoming, supra, 563 U.S. 368, the United
States Supreme Court examined a narrow question: whether an interstate compact barred
an upstream appropriator of native water supplies from using more efficient irrigation
techniques because such efficiencies reduced the amounts returning to the watercourse
for use by downstream appropriators. The Montana court merely concluded the interstate
compact incorporated (and was not intended to alter) background appropriative water
rights concepts, including the right of an appropriator to recapture and reuse his own
waste and seepage before it escapes his possession and control, and that improving
irrigation efficiencies was merely a form of recapture permitted under existing water law.

                                             45.
(Id. at pp. 378–388.) The Montana court did not purport to examine whether an
appropriator is entitled to priority over return flows from native waters that have returned
to the aquifer and is therefore inapposite.32
       The California statutes cited by Phelan do not alter our conclusion. For example,
while Water Code section 71610 does permit a water district to “recycle, recapture, and
salvage any water … for the beneficial use or uses of the district” (id. at subd. (a)), that
section only describes powers of a water district and has never been applied to expand
rights held by a water district. Indeed, because that statute was in effect at the time the
court issued its decision in San Fernando (see Stats. 1963, ch. 156, § 1, p. 823), but the
court nevertheless held extractions of native waters are not accompanied by return flow
rights in such water, we decline to apply that section to undermine the San Fernando
holding.
                                          CONCLUSION
       We conclude substantial evidence supports the judgment as to Phelan and Phelan
was not deprived of its due process rights to present its claims. We also conclude the
court correctly rejected Phelan’s claim its status as a municipal purposes appropriator

       32The other cases      cited by Phelan are equally unpersuasive. For example, in Department
of Ecology v. United States Bureau of Reclamation (1992) 118 Wash.2d 761, the issue resolved
by the court was a narrow question: whether a state agency could grant a permit to a landowner
to appropriate water from a stream where such water was still subject to the appropriative rights
held by the federal government. The stream water in dispute was generated because a federal
reclamation project drew water from the Columbia River and distributed that water to users
within the project boundaries for irrigation and other purposes, but some portion of the water
(after its initial use) then fed a stream that was still within the boundaries of that project. (Id. at
pp. 763–765.) The Department of Ecology court merely concluded the water in the stream was
still subject to the federal government’s appropriation rights (which specifically reserved the
right to recapture and reuse waste and seepage waters generated by the reclamation project), and
because it remained appropriated water owned by the federal appropriator within the project
boundaries, it was not public water and could not be reappropriated by the landowner. (Id. at pp.
767–769.) It appears that the water considered by the Department of Ecology court was more
analogous to water “imported” into the reclamation project’s boundaries by the reclamation
project, and thus according superior rights to the federal importer is consonant with the rights
accorded to importers of water under California law.
