" 001893 Congress of the united States to future authorization of any additional stage of the project. The authorized initial stage project purposes contemplate an average annual project require- ment of 110,000 acre-feet; however, hydrologic studies based on streamflow records for the period 1928 through 1951 show that the initial stage as authorized and constructed is physically capable of diverting an annual average of only about 109,000 acre-feet. There are no current proposals for the authorization of additional stages of the San Juan-Chama Project that would increase its diversion capability. The principal diversion and storage works of the San Juan- Chama Project were completed and first operated in 1971.

In addition, various entities have expressed interest in contracting for about 100,000 acre-feet of project water for municipal, irrigation and other purposes. Approximately 36,000 acre-feet of the water required to fill the Cochiti Reservoir recreation pool has been released and the balance of 14,000 acre-feet will be released later this year. The annual requirement to maintain this pool against evaporation is estimated at 5000 acre-feet.
