<br />. <br /> <br />. <br /> <br />. <br /> <br />3686-a/6 <br /> <br />Evaporation from upstream reservoirs was assumed to remain <br />at the existing 30,000 ac-ft for Scenario I. But for <br />Scenarios II and III, evaporation was considered to be <br />i ncreas i ng because of reservoir projects being planned or <br />under construction to meet water demands for both the Front <br />Range and the Western Slope. Since there are many factors <br />affectin,! the development of large reservoirs, it is <br />difficult, if not impossible, to predict which will be <br />developed. In Scenario II, reservoir evaporation was <br />assumed to increase by 50%, and in Scenario II!, it was <br />assumed to increase by 100%. <br /> <br />Transmountain diversions are predicted to increase even in <br />Scenario I because of projects now under construction to <br />meet the water demands of the Front Range. Current levels <br />of diversion to the Eastern Slope average 538,000 ac-ft/yr. <br />It is expected that virtually all of Denver's, and most of <br />the Front Range's, future increases in water supp ly wi 11 <br />come from the Western Slope. Based on the Colorado Water <br />Conservation Board's Una Reservoir study, future transbasin <br />diversions are predicted to increase by 141,000, 205,000, <br />and 278,000 ac-ft for Scenarios I, I!, and I! I, <br />respectively. <br /> <br />b. <br /> <br />Future Downstream Demands <br />Future downstream demands that will affect the operation of <br />the Webster Hill Reservoir are for agriculture, municipal <br />and industrial uses, hydropower, and the oil-shale <br />industry. Demands for water from the Colorado River <br />Compact were not cons i dered. However, future state-l ine <br />calls could increase the value of the water from the <br />Webster Hill Reservoir, since stored water could be <br />released in dry years to meet Compact calls. <br /> <br />II-9 <br />
