...... -.1 00 t-- The total depletion by these five projects was estimated to be about 60,000 acre-feet annually of which 40,000 acre-feet would be depleted above Blue Mesa Dam. An additional 10,000 acre-feet would be depleted between Morrow Point and Blue Mesa Dams, and another 10,000 acre-feet would be depleted between Crystal and Morrow Point Dams. An increased upstream depletion.of 60,000 acre-feet was assumed in the operation studies for the Aspinall unit in the determination of the water supply available for power generation. In 1973, Reclamation issued a concluding report on its Upper Gunnison project investigations which included the East River, Ohio Creek, and Tomichi Creek units. Although it was concluded that there were limited potentialities for Federal water resource development under existing evaluation criteria and projected economic conditions, Reclamation still recognizes its commitment to allow beneficial development of waters of the Upper Gunnison River Basin up to an amount of about 60,000 acre-feet. Allowing for an existing 4,000-acre-foot depletion of the Bostwick Park Project and assuming the depletion of 21,000 acre-feet is realized on Fruitland Mesa project by 2040, there would be a remainder of 35,000 acre-feet available for depletion. Somewhat arbitrary levels of development were used for the period 1990 to 2010. o. West Divide Project A Feasibility Report was prepared in 1966, and the project was authorized by Public Law 90-537 on September 30, 1968, as a participating project of the Colorado River Storage Project. Advance planning studies have continued and various plans have been considered, but none is feasible based upon current policies and procedures for planning water and related land resources. plans include a mix of water for irrigation and municipal use. A Concluding Report has been drafted to summarize data available. A plan is presented which is not economically justified but totals a 38,200-acre-foot depletion. For planning purposes, an administrative decision was made by Reclamation to defer depletions until after 2030. p. Taylor Draw Reservoir Project Taylor Draw Dam filled in 1984.

Stagecoach Project The Stagecoach Project of the Upper Yampa Water Conservancy District involves construction of a dam on the Yampa River near Steamboat Springs and exchange agreements for water out of Yamcola Reservoir. The project would supply about 4,000 acre-feet of water for irrigation, 1,000 acre-feet for municipal uses, and 9,000 acre-feet for thermal powerplant uses. Depletion values for the irrigation and municipal components were supplied by Reclamation. Depletion values for thermal powerplant uses are discussed under Colorado Ute-Southwest Project on the following page. r. Ruedi Contracts Previous estimates of projected depletions from water contracts out of Ruedi Reservoir were provided by the Lower Missouri Regional Office of the Bureau of Reclamation. They were 0 in 1982, 16,000 acre-feet in 1990, and VI-15
