delivered the opinion of the Court.
This original case, which is here for the fourth time, involves the construction and enforcement of the 1949 Compact

between New Mexico and Texas dividing the water of the Pecos River between the two States. Because of the irregular flow of the Pecos River, the Compact did not specify a particular amount of water to be delivered by New Mexico to Texas each year. Instead, Article 111(a) of the Compact provides that “New Mexico shall not deplete by man’s activities the flow of the Pecos River at the New Mexico-Texas state line below an amount which will give to Texas a quantity of water equivalent to that available to Texas under the 1947 condition.” Pecos River Compact, S. Doc. No. 109, 81st Congress, 1st Sess., Art. 111(a) (1949). The parties have had different views with respect to the “1947 condition” as well as other matters that could not be resolved through the Pecos River Commission, which Article V of the Compact established to carry out its provisions and which can effectively act only by mutual agreement of the two States.

After years of relatively fruitless negotiation, Texas filed this original action in June 1974. We granted leave to file the
In 1979, the Special Master filed a report defining “the 1947 condition” and proposed a river routing study and adoption of a new inflow-outflow manual to be used in determining how much water Texas should be expected to receive over any particular period for any particular level of precipitation under the consumption conditions prevailing in New Mexico in 1947. We adopted that report in its entirety.
Special Master Charles Meyers, Judge Breitenstein’s successor,
Both sides excepted to the Master’s report, and we have heard oral argument. We find no merit in and reject the exceptions filed by Texas and New Mexico with respect to the Master’s calculation of the shortfall that is chargeable to New Mexico. 5
New Mexico also excepts to the proposed remedy for the short deliveries in past years. We find no merit in its submission that we may order only prospective relief, that is, requiring future performance of compact obligations without a remedy for past breaches. If that were the case, New Mexico’s defaults could never be remedied. This was not our approach when the case was here in 1988. We then affirmed our authority to hear and decide Texas’ claim and remanded the case to the Master for a determination of the shortfall. As we said then, a compact when approved by Congress becomes a law of the United States,
New Mexico submits that in the event Texas is found to be entitled to a remedy for the past shortages now ascertained, it should be afforded the option of paying money damages rather than paying in kind. New Mexico’s Exceptions to the Report of the Special Master 40-41. This possibility was discussed to some extent in hearings before the Master, who
The Special Master was rightfully cautious, but the lack of specific provision for a remedy in case of breach does not, in our view, mandate repayment in water and preclude damages. Nor does our opinion in

v.
North Carolina,
As we understand the Master, he did not pursue the matter of monetary relief because he thought it foreclosed by the Compact, not because he thought it inadequate, unfair, or impractical. As we have said, the issue was raised in the hearings, but the record does not permit a confident judgment as to whether a remedy in money, rather than water, would be equitable or feasible. To order making up the shortfalls by delivering more water has all the earmarks of specific performance, an equitable remedy that requires some attention to the relative benefits and burdens that the parties may enjoy or suffer as compared with a legal remedy in damages. “[Sjpecific performance is never demandable as a matter of absolute right, but as one which rests entirely in judicial discretion, to be exercised, it is true, according to the settled principles of equity, but not arbitrarily and capriciously, and always with reference to the facts of the particular case.”

v.
Dobrinski,
It might be said that those users who have suffered the water shortages caused by New Mexico’s underdeliveries over the years, rather than the State, should be the recipients of damages, and that they would be difficult if not impos
We conclude that the matter of remedying past shortages should be returned to the Special Master for such further proceedings as he deems necessary and for his ensuing recommendation as to whether New Mexico should be allowed to elect a monetary remedy and, if so, to suggest the size of the payment and other terms that New Mexico must satisfy.

The attached decree enjoins New Mexico to comply with its Article 111(a) obligation under the Pecos River Compact and to determine the extent of its obligation in accordance with the formula approved by the decisions of this Court. That formula was fashioned in the course of this litigation, which was occasioned by the inability of the Pecos River Commission, on which Texas and New Mexico have the only votes, to agree on how river water should be divided. Neither this opinion nor the decree, however, displaces the authority of the Commission to perform what it has not been able to perform before, namely, an agreed upon and mutually satisfactory formula for division and utilization of Pecos River water. If history repeats itself, the Commission will not come forth with an apportionment different from that which the Court has now approved. If it does, the parties should petition the Court to terminate or appropriately modify its decree as the case may be. Even if the Commission takes no action, it may be that because of the unpredictability and peculiarities of the Pecos, the inflow-outflow methodology we have ordered implemented will not reflect the realities of the river. In that event, it would be appropriate to seek an amendment of the decree, as has been done in other original actions.
In exercising this power, we have taken a distinctly jaundiced view of appointing an agent or functionary to implement our decrees.
Vermont
v.
New York,
Provision for a River Master will occasion an amendment to the decree. On remand, the Special Master is requested to recommend an amendment to the decree, specifying as he deems necessary the duties of the River Master and the consequences of his determinations. Any other suggestions for amendments should also be called to our attention. The River Master’s compensation shall be borne equally by the parties. The parties, as well as the Special Master, are welcome to suggest candidates for appointment as River Master. 9
DECREE
It is Ordered, Adjudged, and Decreed that the State of New Mexico, its officers, attorneys, agents, and employees are hereby enjoined:
(A) To comply with the Article 111(a) obligation of the Pecos River Compact by delivering to Texas at state line each year an amount of water calculated in accordance with the inflow-outflow equation contained in Texas Exhibit 68, at page 2.
(B) To calculate the Index Inflow component of the inflow-outflow and channel-loss equations contained in Texas Exhibit 79, modified to reflect the Court’s decision of June 8, 1987, as to manmade depletions chargeable to New Mexico. “Index Inflow” shall mean the 3-year progressive average of “annual flood inflows” as those terms are defined in Texas Exhibit 79, Table 2, p. 5.
Notes
The Compact was signed by the States in 1948 and was approved by Congress in 1949. Article I, § 10, cl. 3, of the Constitution provides that “No State shall, without the Consent of Congress, . . . Compact with another State, or with a foreign Power . . . .”
The Commission is composed of a representative of each of the States and a third, but nonvoting, representative of the United States.
We also rejected the submission of Texas that “Double Mass Analysis” rather than “Inflow-Outflow” be adopted as the method for determining New Mexico’s delivery obligation under the Compact.
The Special Master recommended and we agreed that Figure 1 and Table 1 of Texas Exhibit 68, pp. 3, 4, properly described the method to be used.
New Mexico’s ongoing obligation under Article 111(a) of the Compact, as now construed and applied by this Court, will be on the average 10,000 acre-feet higher than New Mexico’s deliveries have been in the past.
The Inflow-Outflow Manual incorporated in the Compact proved to be so faulty as to be unusable.
Texas counsel suggested that a money judgment might find its way into the general coffers of the State, rather than benefit those who were hurt. But the basis on which Texas was permitted to bring this original action is that enforcement of the Compact was of such general public interest that the sovereign State was a proper plaintiff. See
Maryland
v.
Louisiana,
If the Special Master recommends and we approve a judgment for money damages, Texas will be entitled to postjudgment interest until the judgment is paid. If damages are not awarded or a damages judgment is not paid, it would appear it would be necessary to make up the shortfall by delivering more water over a period of years as the Master has recommended in his report. In that event, Texas would have a judgment against New Mexico for 340,100 acre-feet of water, plus any additional net shortfalls accruing to the date hereof, which, if not delivered as ordered by the Court, would entitle Texas to apply to this Court for enforcement, cf.
