This is the same controversy over water rights in the Jacaguas river in Porto Rico which was before this court, under the name Veitia v. Fortuna Estates, 240 Fed. 256, 153 C. C. A. 182, decided December 29, 1916. The present appellees, hereinafter referred to as plaintiffs, are a partnership and are the successors in title of the original plaintiff, the Fortuna Estates.
Both the Fortuna Estates and the original defendants had entered into contracts with the people of Porto Rico pursuant to its irrigation laws. The Fortuna Estates had the earlier contract, and in the District Court sought and obtained a preliminary injunction against the exercise by the defendants of certain rights claimed under their contract, but asserted by Fortuna Estates to cover water already contracted to it. The defendants appealed to this court, which held that it was then unnecessary to determine the true construction of the Fortuna Estates’ contract with Porto Rico; that all questions of interpretation should be left unprejudiced until passed upon by the District Court at a hearing wherein Porto Rico had an opportunity to be heard; and remanded the case with directions to afford Porto Rico an opportunity to intervene. Porto Rico intervened, waiving its- immunity as sovereign. Porto Rico v. Rosaly, 227 U. S. 270, 273, 33 Sup. Ct. 352, 57 L. Ed. 507, Russell & Co., having become the successors in title to the Fortuna Estates, were allowed to intervene and file a supplemental complaint, and the original defendants and the people of Porto Rico respectively filed answers thereto, after which the case proceeded to trial.
Under an order of August 24, 1917, pendente lite, the plaintiffs and original defendants, by agreement, divided the water in controversy, each paying one-half the amount claimed by Porto Rico as rent or otherwise, without prejudice and subject to the result of this litigation.
On July 16, 1918, the District Court filed an opinion in favor of the plaintiffs on all issues, entered a decree affirming the validity of all the old water rights or cessions claimed by the plaintiffs, adopted *725the plaintiffs’ construction of their contract with Porto Rico, enjoined both the original defendants and the intervener from diverting or obstrucing the flow of the water claimed by the plaintiffs, and ordered the money deposited by the plaintiff and defendants, pendente lite, paid over to the plaintiffs. As the original defendants did not desire to appeal from this decree, on motion of Porto Rico the suit was severed, and Porto Rico appealed to this court, specifying 31 assignments of error.
The Jacaguas river rises in a mountainous ridge paralleling the southern coast of Porto Rico and runs some 10 miles southerly into the sea. In the rainy season it carries a considerable volume of water. In dry times it entirely disappears from the surface for 2 or 3 miles; but lower down, in what is known as the Maturi Pool, water reappears in substantial quantities, coming down by filtration- through the sandy, porous bed of the stream.
The successful cultivation of sugar cane requires an annual water supply of about 96 inches, delivered as regularly as possible. The rainfall on the south side of the ridge is about one-half that amount. Plence for many years attempts have been made to supplement the rainfall by irrigation from the streams and also from wells. Water rights based on prescription, concessions, and royal decrees of the king of Spain were the actual or alleged appurtenances of most of the estates along the Jacaguas Valley. These concessions and claimed rights exceeded, in the aggregate, the amount of water ordinarily available during parts of the season. Consequently it was necessary to provide for the order in which water takings should be suspended as between the various competing estates. For the efficient and profitable development of sugar raising, a general public irrigation system became necessary. Such a system was provided for by the statute of February 29, 1908, amended by the act of March 9, 1911, and also of August 8, 1913. Acts Sp. Sess. 1913, p. 23. In brief these acts constituted an irrigation commission, provided for irrigation districts, to consist of lands which could be profitably and successfully irrigated, and authorized the construction of dams, reservoirs, canals, etc. These statutes provide various ways for disposing of outstanding actual or claimed water rights; one of which is condemnation, another voluntary relinquishment or agreed compensation in new water rights, and another — the one now pertinent— authorized by section 13 of the act of August 8, 1913, as follows:
“In the case of any land carrying a water right or concession of which me source of supply is destroyed or impaired by the construction or operation of the irrigation system, which shall not have been relinquished or surrendered to the people of Porto Rico, such land shall be entitled to receive from the irrigation system an amount of water which is the reasonable equivalent in value of the said water right or concession.
“The commissioner of the interior is hereby authorized to negotiate with the owner or owners of such water rights or concessions, and with the owner or owners of any water rights or concessions heretofore relinquished or surrendered on condition that the lands to which they are appurtenant should form part of the irrigation district, and which lands have not been included by the irrigation commission, and the said commissioner of the interior shall be empowered to enter into agreements with such owner or owners as to the *726amount of water and the time, place and conditions of delivery thereof, which shall he delivered to the lands to which the said water rights or concessions are appurtenant as the fair equivalent in value thereof, with the power on behalf of the irrigation service to enter into agreement with such owner or owners for the relinquishment to the people of Porto Rico of such water rights or concessions, and for the delivery to the lands to which the said water rights or concessions are appurtenant of such fair equivalent. Before entering into any such agreement the commissioner of the interior shall consult, the Attorney General of Porto Rico as to the validity and legal status of the water rights or .concessions involved.”
The power of the government officials to contract with the owners of water rights was, under this section of the statute, limited to giving in exchange for the old water rights water which would be a fair equivalent in value.
The irrigation development of the Jacaguas river involved damming the river by the Guayabal Dam, about six miles from Maturi Pool, and also bringing into its reservoir the waters of the Toro Negro river from the north side of the watershed, where the normal rainfall appears to be about 100 inches a year, double the rainfall on the south side of the watershed. How much Toro Negro water was thus brought into the Guayabal Reservoir this record does not show.
The Guayabal Dam and other irrigation appurtenances were substantially completed in. March, 1914. Under date of August 26, 1914, a contract was entered into between the plaintiffs’ predecessor in title and Porto Rico, upon the construction of which,- under all surrounding circumstances, the rights of the parties depend. The contract is lengthy, consisting of 16 paragraphs, but for present purposes may be much abbreviated. It recites that Fortuna Estates owns 4 tracts, called Fortuna, Cristina, Euciana, and Serrano, which claim to have appurtenant thereto old water rights aggregating 11,032.79 acre feet of water per year, beside an unlimited right to take torrential waters; that Porto Rico has undertaken the construction of a public irrigation system and erected the Guayabal Dam for the purpose of storing the waters of the Jacaguas and Toro Negro, “a stream arising on the north side of the main watershed,” by which construction the use of the rights claimed “may be interrupted and impaired.” The old rights are stated not to have been relinquished and surrendered; and further, verbatim:
“Whereas, the amount of water taken by the Fortuna Estates and its predecessors in title for the irrigation of said four tracts of land under its said claims of water rights varies from month to month in accordance with' the rainfall in the watershed of the said Jacaguas river, so that it; is impossible to determine in advance the exact amount of water to which the Fortuna Estates is entitled under the said claimed water rights for any fixed period of time, and the people of Porto Rico (notwithstanding the construction and operation of said Guayabal Dam) is ready to deliver from the said Jacaguas river to the said Fortuna Estates the amount of water to which the latter may be entitled under its said concessions, but, in order to facilitate and make more certain the operation of the said dam and the irrigation system of which it is a part, desires to determine and agree upon an amount of water which, delivered regularly, may, under all attending circumstances, be considered to be the fair equivalent in value for irrigation purposes of the amount of *727water which tlie Fortuna Estates would under ordinary circumstances take and use under tlie said water rights and concessions; and”
It is then recited that the commissioner has authority, after consulting with the Attorney General, to agree—
“upon an amount of water equivalent to tlie water taken and used under said water rights and concessions and as to the time, place and conditions of delivery thereof to the lands to which the said water rights or concessions are appurtenant.”
The parties, therefore, agree:
“First, 'ihe parties hereto hereby agree that the quantities of water specified in this paragraph, delivered uniformly through the year, subject to tlie terms and conditions specified in this agreement, together with tlie additional water the right to lake which is provided for or reserved in paragraphs third and fourth hereof, are the fair equivalent in value of the water which the said Fortuna Estates.takes under and pursuant to the concessions and water rights claimed by it, and the people of Porto Rico will, subject to the conditions and limitations hereinafter specified and at the times, places and subject to the conditions of delivery hereinafter provided for, make delivery to the Fortuna Estates for the irrigation of ihe said tracts of land hereinabove referred to, of the said amounts of water to wit” (summarizing) :
For Fortuna, 8,806.45 acre feet per year, which is about 92 per cent, of ihe old claim of 8,572.91 acre feet per year.
For Cristina, 1,812.48 acre feet per year, which is about 48 per cent, of the old claim for 2,728.969.
For Luciana, 1,260.22 acre feet per year, which is about 59 per cent, of the old claim for 2,111.42.
For Serrano, 2,879.63 acre foot per year, which is about 90 per cent, of the old claim for 2,619.769.
The reduction in the amounts allowed from an aggregate of 11,032.78 to 8,258.98 (about 75 per cent.) is grounded on the principle of equivalence, and the variation in the percentage to the different estates obviously rests on the order 'of suspension in times of shortage.
The contract then provides lor the details of regular daily deliveries and of points of delivery' — not now pertinent, except that Cristina is Lo receive 571.27 acre feet or .79 second feet per year of the amount above assigned to it at the Aruz pumping station. This water seems to have been regularly received. The Aruz pumping station is in the Maturi Pool, 774 feet below the Maturi intake, where, by a later contract, the original defendants were authorized to take alleged excess water, the subject-matter of this controversy, for the Boca-Chica estate.
The case turns largely upon the interpretation and application of the third paragraph of the contract, the material part of which is as follows:
“Third. Fortuna Estates is hereby granted the right while this agreement remains in force to lake in addition to all amounts of water above specified, from the Jacaguas river by pump at the said -Aruz pumping station, water which may be available there for irrigation of any of its said lands, to the extent that such taking shall not deprive any owners or users of subsisting water rights or concessions upon the Jacaguas river of the water to which such owners or users may he entitled, either by virtue of such water rights or concessions or by virtue of any agreement or agreements in regard thereto entered into or to be entered into by them with the people of Porto Rico: Provided, however, that should the people of Porto Rico at any time under*728take the development and utilization of tlie surplus waters of this part of the Jaeaguas river, this right shall be understood to be limited to a maximum usage of 3.86 second feet.”
The fourth paragraph, referred to in the first paragraph, deals only with torrential waters, not in controversy, and is not now material.
The contract also contains elaborate recitals by the plaintiffs’ predecessor in title o'f the validity of its old water rights and a provision for a yearly brief use of those rights, in order that the same may not be claimed to have lapsed.
As above stated, the Guayabal Dam was completed in March, 1914, and the contract between the plaintiffs’ predecessor in title and the people of Porto Rico was entered into on the 26th of August, 1914. On December 14, 1915, the people of Porto Rico entered into a contract with the original defendants, owners of the Boca-Chica estate, “to sell or lease excess water” to them for $6 per day, or, if less than 3 acre feet per day, at the rate of $2 per acre foot, delivered at the Maturi intake. This contract was ratified by the Executive Council on February 15,1916.
Prior to August, 1915, the people of Porto Rico constructed a dam across the Maturi Pool at the Maturi intake, 774 feet above the Aruz pump, and about the 15th of August, 1915, began to divert the water through the Maturi intake to the Boca-Chica estate, and continued to do so from that time down to the granting of the preliminary injunction May 18, 1916. In the dam thus constructed at the Maturi intake means was provided for letting down to the Aruz pump the .79 second feet, or 571.27 acre feet, per year, which the people of Porto Rico had contracted with the plaintiffs’ predecessor to deliver there regularly, so that the diversion complained of by the plaintiffs was not of all the water from the Aruz pump, but only of that which they claim the right to take in excess of .79 second feet. That the defendants diverted by means of the Maturi Dam all the water from Aruz pump in excess of .79 second feet is conceded by counsel for the people of Porto Rico in their brief, and the evidence in the case fully substantiates this concession, for the witness Plan-son testified as follows:
“Since that intake was opened, and when the dam was placed in the river, I did not get any water at the Aruz pump over an excess of .79 second feet to which we are entitled, but before the dam was placed there we did receive more water than the .79 second feet that the irrigation service delivered to us regularly. * * * While this dam was in existence we were not obtaining at the Aruz pump any more than the .79 second feet of water which was delivered to us by the daily service. The effect of the construction of that dam was to prevent us from getting any water from the Aruz above the daily amount, and while that dam was in existence water passed through the Maturi Canal going to’ the hacienda Boca-Chica, owned by the defendants Henna and Cabrera in this case.”
He further testified:
“I remember that subsequent to the time when the dam was destroyed an injunction was granted by Judge Hamilton restraining the defendants from taking water at that Maturi Canal, and after that injunction was granted, the old Maturi concession intake was sealed by the marshal of the United *729States court, so that water could not pass in the canal. After that injunction was granted and that canal had been sealed up, we again received at the Aruz pump more than the .79 second feet of, water to which we are entitled as a regular daily delivery, and, although I don’t remember the figures, I think that we got three or four times the amount of water that wo were getting, three or four times the .79 second feet. After the Circuit Court of Appeals had reversed the order granting an injunction, the old intake was not re-opened; but they constructed a dam across the river to raise the water high enough to divert it into the Maturi Canal. The canal which they were using as a result of that dam was a canal which had been opened for the purpose of taking torrential waters. This canal was not an ordinary canal. It was at some distance above the ordinary flow of the river. The dam which was built was from 3% to 4 feet high above the bed of the river, and in order to throw the water into the Maturi torrential intake they raised the water in the Maturi Pool at one time about 4 feet high. The water in the Maturi Pool was about 4 feet deep. While the dam was in operation, -and the water running into the Maturi torrential intake, we did not get at the Aruz pump more than .79 second feet daily.”
It thus appears that by the construction of the Maturi Dam the defendants took and diverted through the Maturi intake all the water otherwise available at the Aruz pump in excess of the .79 second feet which, under its contract, the people of Porto Rico was required to deliver there regularly, and the questions are: What is the right which the plaintiffs acquired by paragraph third of the contract permitting them to take at Aruz pump in Maturi Pool additional waters to those specifically contracted for in paragraphs 1 and 2? and whether that right has been violated by the diversion which took place at the Maturi Dam.
[ 1 ] The plaintiffs take two positions with reference to their claimed right to the surplus water above .79 second feet ‘at the Aruz pump in Maturi Pool: First, that they are entitled to this water by virtue of their old Spanish concessions, which they claim are not suspended by the contract of August 26, 1914; and, second, that they are entitled to it as additional water under paragraph third of the contract. But we think it is apparent from a reading of the contract that their old concessions are suspended while the contract remains in force, and that, as it is still in force, their right to the water in question depends upon the contract. There is, therefore, no occasion for considering the concessions or determining their validity. This was the view entertained by this court when the case was here before. In Judge Dodge’s opinion, referring to the excess water, he said:
“If the plaintiff had any such prior right, it was superseded while the contract was in force, and could be asserted only to the extent that the terms of the contract permitted the taking of such water.” 240 Fed. 201, 153 C. C. A. 182.
The claims of the parties as to the validity, nature, and extent of the old concessions and of prescriptive rights are material only so far as they assist in the interpretation to be put upon the contract. The contract — made under a statute which limited the powers of Porto Rico to contract to grant water rights, described as “the fair equivalent in value” of the old rights or concessions — is the basis upon which the rights of the parties must rest.
*730Under the contract the Fortuna Estates contracted to take, and Porto Rico contracted to furnish, 8,258.98 acre feet per year, delivered regularly as above set forth,' and in addition thereto “water which may be available” at the said Aruz pumping station for the irrigation of any of its said lands under the provisions of paragraph third of the contract, as “the fair equivalent in value” of its. old rights thereby suspended.
[2] Much discussion has been indulged in, both in brief and argument, as to whether the contract and particularly paragraph third should be construed as a grant or as a contract; the contention being that, if it was a grant, it should be construed more strictly as respects the grantee than it otherwise would. We do not regard it material whether this provision of the' contract be regarded as a grant or as a simple contract, as in either event we are called upon to ascertain, if we can, what the parties intended by the language used, viewed in the light of the circumstances surrounding them at the time the contract was made. The evidence shows that, prior to the construction of the Guayabal Earn, there was excess water at the Maturi Pool during the dry season, or a portion thereof, when the bed of the stream from the Pool to the Ursula intake, some 3 miles above, was dry. It also 'appears that, after the Guayabal Dam was built; the amount of water in the Maturi Pool at such times was somewhat increased, and that this was probably due to seepage caused by pressure of the water stored behind the dam. It further appears that the plaintiffs’ predecessor in title obtained more water at Aruz pump prior to the construction of the Guayabal Dam than it obtained there after its construction and the diversion of the water by the Maturi Dam to the Boca-Chica estate, when it received no surplus water, and that the parties, before and at the time of making the contract, August 26, 1914, knew that the amount of water in Maturi Pool in the dry season was somewhat greater by reason of the storage of water in Guayabal Dam than it had been at a like season of the year prior to the construction of that dam.
[3] In view of the circumstances here narrated as existing at the time the contract was made, we think that the people of Porto Rico, by stipulating in the third paragraph of the contract that Fortuna Estates should have the right to “take in addition to all amounts of water above specified, from the Jacaguas river by pump at the said Aruz pumping station, water which may be available there for irrigation of any of its said lands,” intended to give, in addition to the quantities specified in paragraphs first and second, the right to take all the surplus water available at the Aruz pumping station under the physical conditions then existing on this part of the stream for conserving and handling the water, provided such taking should not interfere with water rights or concessions then subsisting on the river or with contracts made or to be made in regard to such subsisting concessions, and that this right should continue down to the time the people of Porto Rico should undertake the development and utilization of the surplus waters of Jacaguas river, when it should be limited to a maximum usage of 3.86 second feet.
*731It was conceded at the trial and found by the court-below that the people of Porto Rico have not undertaken the development and utilization of the waters on this part of the river, so that the latter proviso is now of no consequence.
The additional or surplus waters stipulated for in paragraph third of the contract are not waters that Porto Rico is required to deliver at Maturi Pool in regular daily deliveries, but are waters that are there because of rainfall or seepage and the physical conditions existing on that part of the river. The amount available may be great or little. In dry seasons it is practically certain to be small. But whether great or small, and whether of no particular value when plentiful, and of much value when scarce, it is nevertheless a part of the additional waters stipulated for in the contract going to make up the consideration (the fair equivalent in value) for the old concessions which the contract suspended.
If the people of Porto Rico could maintain a dam near the head of the Maturi Pool, and divert all the water in excess of the .79 second feet which it is required to deliver there regularly, it would be taking away from the plaintiffs the additional or surplus waters which constitute a part of the consideration for the suspension of the plaintiffs’ concessions. We think it is not entitled to do this and that, by erecting the Maturi Dam and diverting all the water in excess of .79 second feet, it has invaded the plaintiffs’ rights.
[4] We are also of the opinion that the court below was right in directing that the affirmative defense set up in the answer should be stricken out. The South Porto Rico Sugar Company is not a party to the action, so that the issue sought to be raised could not be properly determined; and, if it were a party to the suit, it would then be very doubtful whether the issue could be raised except in a direct proceeding instituted for the purpose.
[5] If at the trial evidence was received relating to the construction of the contract which should not have been, we do not find it necessary to consider the defendants’, exceptions to it in detail, for, in the conclusion we have reached, we have not found it necessary to make use of any evidence, the introduction of which could be in any way questioned.
We are also of the' opinion that the decree entered in the court below is too broad and should be modified to read:
“It is hereby ordered, adjudged, and decreed as follows:
“1. That the plaintiffs are the owners of four tracts of land situated in the municipal district of Juana Diaz, island of Porto Eico, known as ‘Fortuna,’ ‘Cristina,’ ‘Luciana’ and ‘Serrano.’
“2. That by virtue of a certain contract entered into by the plaintiffs’ predecessor in title with the acting commissioner of the interior and with the commissioner of the interior of Porto Eico, dated August 26, 1914, and June 8, 1915, set out in the bill, the plaintiffs are entitled to take at Aruz pumping station for the irrigation of their said estates, the surplus water in the .iacaguas river at that point; that is, all the waters in Maturi Pool not necessary for supplying any owners or users of water rights or concessions on the river subsisting August 26, 1914, to which such owners or users may be entitled either by virtue of such' water rights or concessions or by virtue of any agreement or agreements in regard thereto entered, into or to be entered into by them with the people of l’orto Eico.
*732“3. That by virtue of said contract the plaintiffs are entitled to have the surplus waters in the Jaeaguas river as above defined flow down the bed of said river from below the Guayabal Dam to the said Aruz pumping station without diversion or interference by the defendants or the intervener.
“4. That the defendants have obstructed and diverted the flow of the surplus waters of the Jaeaguas river to which the plaintiffs are entitled by virtue of the said contract and to their damage.
“5. That a permanent injunction issue directed to the defendants Emilia V. Henna, viuda de Cabrera, Gustavo M. Cabrera y Henna, William Joseph Cabrera y Henna, Mary Cabrera y Henna, Maud Cabrera y Henna, Rafaela Castillo Veitia, viuda de Cabrera, Maria Cabrera, Enrique Cabrera, and Manuel Leon Parra, and to the intervener, the people of Porto Rico, restraining and enjoining each of them, their servants, agents and employés, from diverting or obstructing the surplus waters of Jaeaguas river as above defined.
“6. That the plaintiffs are entitled, to recover from the intervener, the people of Porto Rico, and the people of Porto Rico is ordered to pay to the plaintiffs, the sum of $441.82 deposited with the clerk of the court by the defendants pursuant to the order of this court dated August 24, 1917, and the sum of $442.01 deposited with the clerk of the court by the plaintiff pursuant to the said order, said sums having been withdrawn by the said intervener, the people of Porto Rico.
“7. That the plaintiffs recover of the defendants their costs in this action, to be taxed by the clerk of the court.”
The decree of the District Court of the United States for Porto Rico, modified as above stated, is affirmed, with costs in this court.
