PART VI FUTURE DEVELOPMENT e c. Homestake Expansion Present uses average about 28,000 acre-feet annually. Phase II of the expansion is expected to be on line by 1990 and yield an additional 20,000 acre-feet annually. Values were supplied by the Colorado Water Conservation Board. d. Independence Pass, Pueblo, and Colorado Springs Expansions and Englewood Present and projected values for these exports were sup- plied by the Colorado Water Conservation Board in a July 28, 1980, letter to Reclamation. e. Fryingpan-Arkansas Project e Diversions through Boustead Tunnel began in 1971. The average annual diversion during the 1971-83 period was 44,000 acre-feet. The diversion in 1983 was 90,800 acre-feet. The operating principles for the project state that diversions will not exceed 120,000 acre-feet in any 1 year and will not exceed a total aggregate of 2,352,800 acre- feet in any consecutive 34-year period. The latter requirement would mean a long-time average diversion of 69,200 acre-feet. Since the historical (1971-83) average diversion has been much less than this, it is likely that in the coming decade or so annual diversions will be much higher than 69,200 acre-feet (provided that water is available for diversion) to bring the historical average back up. f. Windy Gap Construction on the dam began in 1981 and is scheduled for completion in 1985. Facilities of the Colorado-Big Thompson Project will be used to divert up to 54,000 acre-feet per year for domestic use by the cities of Longmont, Loveland, Estes Park, Greeley, and the Platte River Power Authority. The Colorado Water Conservation Board estimates that the full depletions will be on line by 1990. g. Animas-La Plata Project e A Feasibility Report was prepared in 1962, and the project was authorized by Public Law 90-537, September 30, 1968. A Definite Plan Report was approved in August 1980. The plan provides for large amounts of water for irrigation and municipal and industrial use and totals a 154,800~acre-foot depletion--120,700 acre-feet in Colorado and 34,100 acre-feet in New Mexico. Construction will not likely start before fiscal year 1986. Depletions will not begin until the early part of the 1990's when Ridges Basin Reservoir is completed. Uses will build up rapidly as other project facilities are constructed. The ulti- mate depletion of l21,000 acre-feet would be possible by 2000. 40
