<br />C) <br />o <br />(""' <br />(.T.l <br />....:1 <br />CJl <br /> <br />o <br /> <br />The Shoshone Hydroelectric Power Plant demand measured at Dotsero is equal to <br /> <br /> <br />1250 cfs all year long. (The additional 158 cts right with a priority date ot 1929 was <br /> <br /> <br />not incorporated because the effect on the monthly tlows of the Study would be <br /> <br /> <br />Insignificant). <br /> <br />Green Mountain Reservoir Ooeration <br />o The 52,000 af replacement pool of Green Mountain Reservoir has first priority tor <br />filling and is reserved to provide replacement water for out-ot-priority CST project <br />diversions. <br /> <br />o Releases from the 100,000 af power pool of Green Mountain Reservoir are used to <br /> <br />make up natural water shortages for those irrigation and domestic water rights <br /> <br /> <br />perfected by use prior to October 16, 1977. For the purpose of thi.s Study, an annual <br /> <br /> <br />release of up to 66,000 af was utilized during the irrigation season (assumed to be <br /> <br />April through October) to satisfy the Grand Valley demand and to relieve shortages to <br /> <br /> <br />other diversions senior to October 16, 1977 that are caused by the Shoshone or <br /> <br />Cameo call. <br /> <br />o The remaining water available from the 100,000 af power pool in Green Mountain <br /> <br />Reservoir is used to meet the demands for water sales at a maximum level of 22,800 <br /> <br /> <br />af/yr as projected in the Draft Water Marketing Program Environmental Statement <br /> <br />(RCI,1985). <br /> <br />o During the non-irrigation season (assumed to be November through April) releases <br /> <br /> <br />from Green Mountain Reservoir are made for power production and replacement ot . <br /> <br />CST out-ot-priority diversions. Winter releases are used to drawdown the reservoir to <br /> <br />a level between 40,000 and 60,000 af by April depending on the-anticipated infiows <br /> <br />during the snowmelt season. <br /> <br />4-4 <br />
