. . , . . ~ Western concluded from their studies that their assumed demand from Rangely Reservoir could be met during a repetition of the drought years 1977-1978 with a release of 200 cfs from Rangely Reservoir, e~uivalent to approximately 238 cfs flow into Utah. Western further concluded that their assumed demand could not be obtained for a period of approximately 9 months during a repetition of the drought years 1977-1978 with a release of 300 cfs from the reservoir, which would result in a flow somewhat greater than 300 cfs into Utah.

Bingham Engineering Co. of Salt Lake City, Utah, prepared a report in May, 1978, titled "White River Dam, Design Data." The subject of this report, is a proposed dam and reservoir to be located on the White River near Bonanza, Utah. This report is based on the assumption that inflow to the reservoir will be equivalent to the h' treamflow at the Watson Gage (702 cfs average) which is approximately equivalent to the historic stream flow from - Colorado to Utah. If the projected yieldS from the White River Reservoir ~ are to be realized, it appears that the releases from Rangely Reservoir would have to be considerably greater than 300 cfs. 0286 The various studies show that the yield from Rangely Reservoir and the White River Reservoir are interdependent, particularly in years of low stream flow. The yield from Rangely Reservoir is highly dependent on tbe required releases from Range1y Reservoir, The yield from the White River Reservoir will be determined by the inflow into t~e reservoir and the required down- stream releases from the reservoir. The yield cannot be determined for .\ '. \ i--~ . 5
