.onorable Harold Iokes (2) power plants (two drops-110 ft. and 500 ft.) Reservoir Capacity 60,000 A. Ft. Dead water 10,000 " " Svaporation loss 9,000 " " Leaving for annual diversion 41,000 " n There is an alternative project (much more expensive) that would permit the use within Utah of an additional 10,000 acre feet. 2nd. The building of a reservoir on Santa Clara Creek of a capacity of 20,000 acre feet will safeguard present use, provide supplemental water for 2,000 aores now cultivated and a full water supply for an additional 2,000 acres of new land.

The evaporation loss will be 3,000 acre feet-making the additional consumptive use on Santa Clara Creek 12,000 acre feet. 3rd. Development on Kanab Creek will require the consumptive use of an additional 5,000 acre feet. RECAPITULATION: Present use of water in Utah within the Lower Basin: 69,000 A. Ft.
