<br />. <br /> <br />31 <br /> <br /> <br />. <br /> <br />thOl storage of the increased Fort Collins return flOl-TS <br />under the plains storage rights. This increase was <br />determined as the difference between the historic diver~ <br />sion to storage of 76,500 acre-feet per year (Col 1, <br />Ta.ble 6) and the total diversion to storage under the <br />anticipated combined operation of 81,000 acre-feet per . <br />year (Col 9, Table 6) 7--~------~------------------~ 4,500 AF!.Yr <br /> <br />3--Eva,pora.tion savings. The abandonment and diminished <br />use of some plains reservoirs due to the consolidation <br />vill reduce the evaporation and seepage losses by an <br />estimated 2,400 acre-feet a year. This rough estiL1flte <br />of saving was assumed to occur each year and has not <br />been sufficiently defined to include in any operation <br />studies ---~---------------------------------------- 2,400 AF/Yr <br /> <br />Tota11fater developed by the consolidation, capacity <br />replacement, and transfer of plains storage <br />rights -------------------------------------------13,000 AF/Yr <br /> <br />. <br /> <br />The estiLated historic operation of the storage decrees in <br />the plains reservoirs is summarized in Table 6. The anticipated <br />combined operation of the storage decrees in the consolidated <br />storage ~n the unit reservoirs and in the remaining plains reservoirs <br />is also sUllmarized in Table 6. <br /> <br />The average annual release of the water stored under the trans- <br />ferred decrees from Grey Mountain Reservoir is 33,100 acre-feet and <br />the averl1ge annual release from the remaining plains reservoirs is <br />37,100 acre-feet, giving a combined annual release of 70,200 acre- <br />feet. The increased average annual release over the historic <br />release of 59,600 acre-feet is 10,600 acre-feet. The water savings <br />realized by the evaporation and seepage reduction of 2,400 acre- <br />feet per year vouJ.d be in addition to this increased release, giving <br />a total ,nater developed by the consolidation of 13,000 acre-feet <br />per year as indicated in Table 6. <br /> <br />The Carriage Lo~ <br /> <br />It was assumed in these hydrologic studies that the irrigation <br />releases from storage at Grey MOUJ1tain Reservoir vould be reduced by <br />a carriage loss estiL1flted at 10 percent of the release. This loss <br />applies to the releases from the plains reservoir consolidation at <br />Grey Mountain Reservoir of 33,100 acre-feet per year(Co1. 5, <br />Table 6) and to the 6,100 acre-feet per year of stored surplus <br />
