<br />5 . utah <br /> <br />J-4 <br />-.J <br />00 <br />W <br /> <br />a. Miscellaneous Additional Depletions <br /> <br />Values used for 1985 represent additional depletions that have <br />developed since the Comprehensive Framework study (1965 level) estimates were <br />prepared. These values and the projections to 2010 were provided by the Utah <br />Division of Water Resources. <br /> <br />b. Bonneville Unit, Central Utah project <br /> <br />Present depletions from the Bonneville Unit include reservoir <br />evaporation, storage accrual, and irrigation uses from Currant Creek, <br />strawberry, Soldier Creek, and Starvation Reservoirs. Project storage which <br />was accruing in Strawberry Reservoir was spilled into Soldier Creek Reservoir <br />in 1983 because of high runoff conditions and prior storage rights of the <br />Strawberry Valley Water Users in Strawberry Reservoir. Reservoir water <br />surface elevation limitations in Soldier Creek Reservoir further reduced the <br />capability of storing water for project purposes. Net depletions to the <br />Colorado River System in 1985 are estimated to be about 53,000 acre-feet. <br /> <br />Based upon the present construction schedule, the depletions to <br />the Colorado River are expected to rise to 136,000 acre-feet by 1990 and <br />166,000 acre-feet by 2000. The latter figure is correct if replacement of an <br />increased fishery bypass for maintenance of fishery flows for streams along <br />the Strawberry Aqueduct of up to 37,000 acre-feet is developed in the Uinta <br />Basin. If alternate supplies are developed in the Bonneville Basin, the <br />depletion from the Uinta Basin will ultimately be about 128,000 acre-feet <br />rather than 166,000 acre-feet. <br /> <br />c. Upalco Unit, Central Utah Project <br /> <br />The March 1980 Definite plan Report and the May 1981 Supplement <br />thereof estimated total depletion of 11,900 acre-feet. The control schedule <br />dated August 1983 indicates Taskeech Dam completion in 1990 and initial <br />filling to occur at that time; however, recent decisions have been made by <br />Reclamation to suspend activity on this unit indefinitely. Primary uses are <br />for municipal, industrial, and supplemental water for irrigation.

Jensen Unit, Central utah Project <br /> <br />The Definite plan Report was revised in 1976. The <br />plan provided irrigation water primarily for supplemental service and water <br />for municipal and industrial use. Evaporation and irrigation consumptive use <br />totaled 3,000 acre-feet in 1985. Total depletion is estimated at 15,000 <br />acre-feet. The project depletion would gradually increase to the full amount <br />by 1990. <br /> <br />e. Uintah unit, Central Utah Project <br /> <br />A report for certification of physical, economic, and financial <br />feasibility dated April 1975 was certified by the Acting Secretary of the <br />Interior on August 22, 1975; approved by the Office of Management and Budget <br />on March 25, 1976; and forwarded to Congress on April 6, 1976. Project water <br />supply uses are primarily for supplemental irrigation service to Indian and <br /> <br />VI-17 <br />
