. . ~ of WaCer from Rangely Reservoir, and chat che holder of such senior right would be entitled co use all of the water granted under his right even if such use reduced or completely depleted the water available from Rangely Reservoir. As a part of the assessment of the reliability of Rangely Reservoir as a water supply, the David E. Fleming Company (Fleming), a consulting engineering company with offices in Denver, Colorado, was engaged to perform simulation studies of the White River Basin in Colorado. An existing computer model, called CORSI}!, was used by Fleming for the studies. ------ For the CORSI}! analysis, Fleming made assumptions as to which of the conditional water rights senior to Rangely Reservoir would be developed in the future and whether they would be developed at less than or up to the full decreed amounts. These assumptions were made based on Fleming's knowledge of stream flow characteristics of the White River Basin and the then known planned and projected industrial, irrigation and municipal water projects for the area. A description ~ of ~he assumptions used for the CORSIM analysis was prepared by Fleming in January, 1975, A copy of this description titled "Base Problem File, ~~ite River Basin" is attached. Table II of the Base Problem File lists the condi- tional water rights which were used in the CORSl}l analysis. The CaRS 1M studies indicated that, if future development and use of water from the White River proceeded in accordance with the assumptions used, Rangely Reservoir would produce an average yield of approximately 92,000 acre-feet per year. The average flow into Utah would be approximately 0288 3 , ,
