Action by the State Engineer for a Declaratory Judgment construing an agreement entered into by the Piute Reservoir and Irrigation Company and the Sevier Bridge Reservoir owners October 18, 1938, with reference to the water of Sevier River. The State Engineer is virtually a nominal party, the real controversy being between Piute Reservoir and Irrigation Company, defendant and appellant, and Sevier Bridge Reservoir Owners, defendants and respondents. Hereinafter appellants will be referred to as Piute, and respondents as Sevier. Piute maintains a storage reservoir on Sevier River above Marysvale. Further down the river, approximately 82 miles as the water flows, Sevier maintains a storage reservoir. Both are maintained for storage of irrigation waters, and are subject to the direct flow primary rights on the river. This action is concerned only with these storage waters.
There had been considerable litigation over the waters of the river, and, on November 30, 1936, the District Court of Millard County in the case of Richlands Irrigation Company v. WestviewIrrigation Company et al., made a general adjudication of the waters of the river. This decree provided that beginning with October 1st of any year and ending with October 1st of the succeeding year of the water available for storage after satisfying primary rights, Sevier was to receive 89,280 acre feet of water as a first priority; Piute was then to receive 40,000 acre feet as the second priority. After satisfying these priorities and amounts then of the next 32,000 acre feet 75% was allocated to Sevier *Page 80 and 25% allocated to Piute; of the next 13,720 acre feet, Sevier should take all. The next 75,000 acre feet was allocated, Piute 25% and Sevier 75%. The Decree further provided that as far as practicable, storage in both reservoirs should be concurrent, but because Piute reservoir is located above Sevier reservoir, water should be held in Piute reservoir as long as possible in order that the make of the river below Piute dam, in excess of primary rights, may be given as long a time as possible to supply Sevier's priority. To clarify this provision the Decree provided that water need not be released from Piute reservoir for transmission to Sevier until after the 15th day of April of each year. Because while water could be released from Piute to Sevier, once the water had passed Piute dam, it could never be recovered by Piute and large quantities of water needed to fill Sevier's first priority was often stored in Piute reservoir until after April 15th in order that Piute would be certain to have in its reservoir all the water to which they were entitled.
So at times it developed that water which had been impounded in Piute reservoir must after April 15, be let down to Sevier to satisfy its first priority of 89,280 acre feet. Due to the fact that there was then a greater loss in seepage and evaporation than during the winter months, and by April 15 water for irrigation purposes was being diverted through numerous canals from the river between the dams, and it was difficult to keep such canal diversions from drawing off part of the waters let down for storage at Sevier, it was necessary in order to meet Sevier's priority to let down from Piute dam a much greater quantity of water than would reach Sevier. This difference as loss in transmission was estimated by the Commissioner at 30%. The net result was that both parties hereto were suffering a loss of water in their respective storage rights. In dry years when the flow available for storage was less than the first priorities of 89,280 acre feet to Sevier and then 40,000 acre feet to Piute, all losses in transit from Piute to Sevier would fall first and most heavily upon Piute, and may also *Page 81 directly affect Sevier. In years when those first priorities were filled, the same situations with respect to losses in transit may arise as to the next 32,000 acre feet which were allocated 75% to Sevier and 25% to Piute; and so on as to all subsequent allocations between these parties. Difference between the parties over such matters resulted in litigation in 1937. In 1938 Piute and Sevier, in an effort to prevent litigation and adjust the difficulties, entered into the agreement involved in this action.
This agreement was an endeavor to work out a plan of distribution whereby the water stored in Piute reservoir could be released to the Sevier reservoir at such times and in such quantities as to prevent loss of water. It provides that the River Commissioners operating under the direction of the State Engineer shall on and after January 1st of each year, release from Piute reservoir for transmission to Sevier reservoir so much of the water accumulated from the storage filings as was necessary to satisfy the priority of Sevier without jeopardizing the water allocated to Piute under the decree. The agreement provided that if more water reached Sevier than had been awarded it under the decree, Piute under certain conditions was to receive credit therefor the following year as against Sevier's first priority of 89,280 acre feet.
During the years of 1938-39-40 and 41 the River Commissioners operated and controlled the reservoirs under the Agreement without material controversy; they measured the water April 15th of each year, as provided by the decree, and gave Piute its credit if entitled to any the following year as was provided by the agreement.
In 1943 by March 30th, both Sevier and Piute had in their respective reservoirs more water than their respective first priorities. Such excess storage plus the make of the river after that date and available for storage, became part of the waters constituting the subsequent priority on the stream, allocated by the decree as 75% to Sevier and 25% to Piute. Of the water thus available under such allocations Sevier received 13,280 acre feet over its allocated 75%. In *Page 82 1944, Piute claimed a credit for this amount less reservoir deductions, against Sevier's first priority of 89,280 acre feet. Sevier resisted allowance of the credit, and the Engineer brought this action for a declaratory judgment construing the agreement between the parties as to when such credits were to be allowed Piute.
At the inception of this action Piute apparently took the broad view that under the agreement it was entitled to credit against Sevier's first priority of 89,280 acre feet for any and all waters available for storage which the previous year reached Sevier reservoir, in excess of Sevier's allocated quantities or proportions less reservoir deductions. As Sevier construed the agreement, Piute was only entitled to credit for waters which Sevier received in excess of its quotas due to error of the Commissioners in under-estimating the make of the river below Piute dam, and therefore allowed too much water to flow down to Sevier from Piute reservoir.
After hearings were had the district court filed a memorandum decision which indicated holdings favorable to Piute. Before formal findings and judgment were entered, Sevier requested leave, and over objections of Piute were permitted to reopen the case, file amended pleadings and offer further testimony. On April 23, 1945, the trial court entered its Findings of Fact, Conclusions of Law and Decree from which Piute appeals, and presents the following questions:
1. Was it error to permit Sevier to reopen the case and amend its pleadings after the court's memorandum decision?
2. Did the amended pleadings, filed after the case had been submitted and a memorandum decision filed by the court, set up a new and different theory of the case?
3. Under the agreement of October 18, 1938, to what waters, and to what extent may Piute claim a credit against Sevier the following year?
Questions 1 and 2 are so closely related that we answer them together. That the court may allow amendment to pleadings under circumstances as was done here if the *Page 83 amendments do not set up a new and independent cause of action is settled by prior decisions of this court. 1, 2Hartford Accident Indemnity Co. v. Clegg, 103 Utah 414,135 P.2d 919; Larson v. Gasberg, 43 Utah 203, 134 P. 885;Peterson v. Union Pacific R. Co. 79 Utah 213, 8 P.2d 627. The amendments allowed in the instant case did not change the questions or issues to be determined. If they made any changes at all except in verbiage, it was merely to expand and amplify what was alleged in the original pleading. The action was instituted by the State Engineer for a judgment construing section 2 of the agreement of October 18, 1938, as to the circumstances and conditions under which Piute was entitled to "credits" for water in Sevier reservoir. There was no change as to that issue nor as to the respective position of the parties with regard to their construction and meaning of the agreement on that question. Piute was given full opportunity to present further evidence and argument on the matters involved. Under the Peterson and the Hartford Accident cases cited supra, question 2 must be resolved against appellant.
3. Under the agreement of October 18, 1938, what are Piute's rights as to "credits" against Sevier? That is the heart of this lawsuit, and involves the construction of 3 Section 2 of the agreement. We set out the parts of the contract that may be helpful in the consideration of this question.
The Witnesseth Clause declares that the purposes of the agreement are: to lessen and decrease losses in the water in transmission from Piute reservoir to Sevier reservoir; and to facilitate the allocation of waters of Sevier River as between Sevier and Piute as provided in the decree.
Section 2 of the agreement reads:
"In order further to decrease or lessen losses in transmission of waters between Piute Reservoir and Sevier Bridge Reservoir, and to facilitate the allocation of the waters between said reservoirs year after year, the Sevier Bridge Reservoir Owners agree with Piute Company as follows: (a) — The RiverCommissioner or Commissioners, under the direction of the State Engineer of the State of Utah, shall, *Page 84 on and after January 1st of each year, release from PiuteReservoir for transmission to Sevier Bridge Reservoir so much ofthe water accumulated or accumulating from the storage filings set out on page 185 of the decree of November 30, 1936, in Piute Reservoir, as may be released without jeopardizing the receiptand use by the Piute Company of the water allocated to it under said decree and under the provisions of this agreement, notexceeding, however, such an amount as in the judgment of said officials will, with anticipated accretions from below saidreservoir, deliver into the Sevier Bridge Reservoir thewater to which Sevier Bridge Reservoir shall be entitled under said decree. (b) — If in any year the Sevier BridgeReservoir shall have received more than its proper proportion ofthe storage waters of the Sevier River allocated to it under said decree, whether from excessive release of water from PiuteReservoir, or from accretions to the river below Piute Reservoirexceeding the amount for which allowance had been made, or fromany holdover water belonging to the Piute Company by reason ofits being a stockholder of the Deseret Company, such excess water, whether held in Sevier Bridge Reservoir or used by the Sevier Bridge Reservoir Owners, shall be credited (less its proper proportion of loss as hereinafter provided) to PiuteCompany, and be accounted as a part and as satisfying to thatextent the first priority of the Sevier Bridge Reservoir forthe said following year, and the said Piute Company shall be, during said following year, entitled, by reason of such credit to withhold, store and use from waters accruing under said storage filings, an amount of water equal to the amount of water so received in the Sevier Bridge Reservoir, less said deduction, before the owners of the Sevier Bridge Reservoir shall be entitled to receive any waters accruing from said storage filings to satisfy the balance of its first priority of 89,280 acre feet for said year.
"3. Each of the parties hereto who may hold over any water in Sevier Bridge Reservoir, as herein provided, shall bear his or its proper proportion of the reservoir loss. The reservoir loss for the holdover period shall be properly computed by the River Commissioner or Commissioners under the supervision of the State Engineer, and shall be applied uniformly and proportionately against all water so stored." (Italics ours.)
The parties are agreed that Piute has no general storage rights in Sevier Reservoir; that is, it cannot of its own volition run its waters down to Sevier reservoir and store them there, and then at its pleasure in future years withhold from the flow of the river at Piute Reservoir water which should flow down to Sevier. They also agree that Piute is not to be held to have lost its right to all water which *Page 85 passes the Piute dam. The waters to which Piute is entitled under the general adjudication decree of 1936, reaching Sevier reservoir and which Piute may offset the following year by withholding waters to which Sevier would be entitled under its first priority, are set forth by three classes or sources in the first sentence of subdivision (b) of Section 2 of the Agreement. Such excess waters (waters belonging to Piute) received by Sevier at its reservoir may consist of: Source 1 — waters released from Piute Reservoir; Source 2 — accretions to the river below Piute Reservoir; Source 3 — such part of the waters of the Deseret Irrigation Company, which had storage rights in Sevier reservoir, as Piute by reason of being a stockholder in the Deseret Company, would have been entitled to draw from the Sevier reservoir and which it did not draw but held over to the following year may be used as a credit or offset against Sevier the spring following the nonuse; as to this right there is no dispute between the parties, and therefore no further reference to it will be made.
The first source which forms one of the bones of contention is "excessive release of water from Piute reservoir." Sevier contends that this "excessive release of water" applies only to a situation where the Commissioners estimated the make of the river below Piute dam as insufficient to supply Sevier's priorities, and then to make up the estimated deficiency in Sevier's supply released from Piute Reservoir more water than was necessary to make up the actual deficiency. That in effect means that the first two classes or sources mentioned above in this opinion are to be construed together as one, notwithstanding they are separated by the disjunctive or in the agreement. Piute argues that regardless of the cause for which the water which should belong to Piute is released at Piute dam, such amount thereof as reaches Sevier reservoir, less storage losses, shall stand as a credit for Piute against Sevier the following season. As shown by the factual statement supra, in 1943, the first priority, Sevier's 89,280 acre feet, had been satisfied: the second priority, Piute's 40,000 acre feet, was also satisfied; *Page 86 and the parties were receiving the subsequent or pro rata priorities. On April 12 the water in Piute reservoir reached the 76 foot contour and was not permitted to raise above that point. Realizing that the make of the river above Piute dam would be more than Piute Reservoir would impound at its 76 foot contour the Commissioners prior to April 12, allowed 9,900 acre feet to by-pass Piute dam, of which 3,847 acre feet reached Sevier reservoir in excess of its allocations and is part of the 13,226 acre feet involved in this dispute. The balance of the 13,226 acre feet, to wit 9,379 acre feet, is the proportion of the make of the river below Piute dam, which the writer thinks was allocated to Piute by the Decree. In 1944, Piute asserted a credit against Sevier for 3,847 acre feet as resulting from "an excessive release of water from Piute reservoir," and to 9,379 acre feet as belonging to Piute from accretions to the river below Piute dam.
As to the 3,847 acre feet, Sevier contends this was not the release of an excessive quantity of water from Piute reservoir, but the natural flow of the river over and above Piute storage capacity, That Piute is limited in its storage rights to the amount of its available storage capacity; that the reservoir was full and this water is to be considered, not as water released from Piute but as water going over the spillway. Piute counters that at the time this water was permitted to pass Piute dam the reservoir was not full, and that even if it subsequently filled, this 3,847 acre feet was released from Piute reservoir and therefore should stand as a credit for Piute. The agreement recognizes no credit rights in Piute for waters forming above Piute dam and which by-passes the dam when the reservoir is full. Piute would have the right to use the water or to store it but not in Sevier reservoir, so the claim on this ground must be disallowed. Piute also argues that its reservoir was not full. The reservoir had storage capacity to the 80 foot contour, and it is admitted that the water level was held at the 76 foot contour; had the Commissioners not released water above the dam until the 80 foot contour was reached *Page 87 this 3,847 acre feet would have been stored in the reserovir and therefore it constitutes an "excessive release" of water. Sevier answers, and the trial court so found, that the waters of Piute reservoir were held at the 76 foot contour at the express orders and direction of Piute, because waters impounded above the 76 foot countour would flood private lands over which Piute had no flood rights and subject the company to damage suits. This finding by the court is amply sustained by the evidence. While this 3,847 acre feet was water allocated to Piute by the decree, which Piute could use or store wherever it had capacity, it is not waters for which Piute can claim credit against Sevier as resulting from "excessive release of waters from Piute reservoir." As to waters forming above Piute dam, the agreement allows Piute credit against Sevier, only for such waters as are permitted to by-pass the Piute dam and reach Sevier, in years when Piute has available and usable storage capacity which it desires to use.
As to the 9,379 acre feet, Piute claims credit for this amount under that provision of the agreement designated as source 3 as Piute's share of the accretions to the river below Piute dam after all prior rights were satisfied, that is, accretions to the river below Piute reservoir, available for storage, exceeding the proportion of such waters to which Sevier was entitled under the decree. Prior to the making of the agreement of October 18, 1938, all the make of the river below Piute dam, and available under the storage filings went into Sevier reservoir, and such proportions thereof as the decree awarded to Piute was lost to it, because it had no way of getting such water up into its reservoir. To safeguard Piute in this regard as far as practicable, the decree provided that Piute could hold at its reservoir the entire flow of the river above its dam until April 15th. If on that date Sevier had not received its priorities and proportions, Piute must release from its reservoir enough water to deliver into Sevier reservoir the amount it was shy on its priorities on April 15th. Such released water suffered a loss of at least thirty per cent in *Page 88 transit, so Piute was compelled to release almost fifty per cent more water than reached Sevier. This often caused a loss of water to both parties sometimes on their first priorities, and sometimes on the later priorities and allocations. As a result disputes and difficulties arose as to quantities of water each received, as to who should stand the loss, and as to when and if Piute should let the water down to Sevier. When the agreement was made, the parties, mindful of these practical difficulties, provided that in order to save this transmission loss, if Piute would open the gates at its dam to insure Sevier getting its first priority without this big transmission loss, Sevier would for a one year period protect Piute in its rights in the make of the river below Piute dam. Thus instead of Piute holding at its reservoir over its quota enough water to offset such water as Piute might be entitled to receive from the make of the river below Piute dam and which flowed into Sevier reservoir, Sevier agreed to let Piute withhold such amount less reservoir losses the following year. This would tend to remove difficulties resulting from the uncertainties in the make of the river each year, by equalizing on a two year basis. The language of the agreement is that Piute should have credit for excess water received by Sevier from "accretions to the river below Piute Reservoir exceeding the amount for which allowance had been made." Sevier now contends that this means exceeding theestimated shortage of the make of the river below the dam to fillSevier's first priority; and to make up which shortage, watershad been released from Piute Reservoir. Such construction means that credit for such accretions would be the same as the credits for "excessive release of water from Piute Reservoir" although the two are separated in the agreement by the disjunctive or, signifying a separate or different thing or class. We have already held that the language "excessive release of waters from Piute Reservoir" dealt with such credits. We conclude both from the language of the instrument and from the oral testimony received by the court, that Piute is entitled to credit against Sevier for waters allocated to Piute by the decree from the make *Page 89 of the river below Piute dam, and which Sevier uses the year of its flow or which is available for use of Sevier the following season. The language "exceeding the amount for which allowance has been made," allows Piute credit for its proportion of the make of the river below the dam against which it had not been allowed to withhold waters forming above the dam either because the waters had been let down over the dam, or because there was no water forming above the dam that could be withheld in Piute. The 9,379 acre feet involved in this dispute flowed into Sevier Reservoir at a time when Piute Reservoir was full to the 76 foot contour. Therefore it was not water for which Piute was entitled to credit against Sevier. In the writer's opinion Piute should be given credit for such excess waters reaching Sevier reservoir only when Piute has unused storage capacity available in its reservoir where it could have stored such water had it been made above the dam. When Piute had no storage capacity available, the waters forming below the dam are in the same situation as the waters forming above the dam. Piute is not entitled to credit against Sevier for any excess waters received by Sevier at such time as Piute Reservoir is full.
During the trial the court received oral evidence from both sides as to circumstances under which the agreement was made, and the negotiations which culminated in the agreement. The receipt of this evidence is assigned as error. We think the written instrument is clear enough in its terms and purports, and lends itself reasonably only to the construction given above. If, however, the parol evidence is considered it impels the same interpretation and construction we have given the instrument. Since the result must be same with or without the parol evidence its receipt was in no way prejudicial.
The writer thinks the decree of the trial court was in error in the particulars indicated in this opinion. The majority of the court thinks the decree should be affirmed. It is therefore ordered that the decree be and same hereby is affirmed — each party to bear their own costs. *Page 90
