B-IO Hogback Expansion Minor increases in depletions are expected to occur between now and 1990. Studies are underway by the Bureau of Indian Affairs and the Navajo Tribe to determine additional water requirements in this area. Utah International, Inc. ~ Approximately 22,000 acre-feet were used for the five units of the Four Corners Powerplant in 1980. Uses varied between 18-22,000 acre-feet during the period 1976-80 with an average of 20,400 acre-feet. As indicated below under discussion of the San Juan Powerplant-New Mexico Public Service, additional water would be obtained from Utah International for Unit No.4. . This, together with increased use of the five units at Four Corners, will require the bulk of the remaining water under this right. Farmington Municipal and Industrial The city of Farmington, New Mexico, is expected to develop additional water for municipal and industrial use of 1990 under rights held by the city. Navajo Indian Irrigation Project Various estimates for projected agricultural use depletions have been prepared, including the studies for the all-sprinkler irrigation system for the Navajo Indian Irrigation Project prepared by the Southwest Region of the Bureau of Reclamation. This study estimated agricultural consump- tive use of 226,000 acre-feet. Several other estimates have been made, and a 5-year field study to determine actual consumptive use on the project was begun in 1978 and will continue through 1982. Recent technical estimates reported in a Secretary, Department of the Interior Report, Economic Study, May 1980, are 254,000 acre-feet for agricultural depletions. In November 1981 it was concluded and agreed by Interior's Assistant Secretary - Land and Water Resources and Assistant Secretary - Indian Affairs that the project's productive acreage should be 110,630 acres, rather than the 105,000 acres which had been assumed in the past. Correspondingly, the annual depletion estimate has been revised froo 254,000 acre-feet to 267,000 acre-feet. The first block of land (about 9,300 acres) was irrigated in 1976. Blocks l through 3 and part of Block 4 were served in 1980 with an estimated depletion of lOO,OOO acre-feet. Water is expected to be delivered to the remainder of Block 4 in 1981. Water is expected to be delivered to Block 5 through 9 by 1990 and the remainder (Blocks 10 and Il) during the 1990's. Jicarilla Apache Indian Uses This depletion is based upon preliminary results of planning studies. Results, to date, indicate that about 3,000 acre-feet could be depleted under present proposals. Studies are continuing to develop plans for additional depletions, but no more feasible uses have developed. In a letter of July 9, 1976, to Mr. S. E. Reynolds, Secretary, New Mexico
