<br />002~60 <br /> <br />Annual depletions due to the High Savery Project are expected to average 7,724 AF. Of this <br />amount, approximately 869 AF is attributed to evaporation from the reservoir, and 6,855 AF is <br />attributed to irrigation. This project assumes that no additional acreage will be brought under <br />irrigation; it will provide supplemental late-season water to currently irrigated lands, If 6,855 AF <br />of annual irrigation depletions due to High Savery are added to 20,050 AF of estimated current <br />annual irrigation depletions, total annual depletions for irrigation would be 26,905 AF, essentially <br />] 00% of the CIR, High Savery depletions have been formally addressed in a biological opinion <br />issued by the FWS on July] 4, 1999; therefore, this project is included under current depletions even <br />though it has yet to be constructed. <br /> <br />The towns of Baggs and Dixon, with a combined population of only 375, account for 76 AF of <br />annual in-basin M&I annual depletions. However, trans-basin diversions to serve the City of <br />Cheyenne account for 14,400 AF of annual depletions, second only to irrigation in depletions from <br />the Little Snake River. Total average annual depletions from the Little Snake River subbasin in <br />Wyoming have been estimated to be 42,583,AF as of 1994 (Table] I). States West Water Resources <br />(2000) estimated that annual depletions from the Little Snake in Wyoming could grow by 23.428 AF <br />to an average annual depletion of 66,011 AF by 2045 (Table 12). <br /> <br />Table I I, Current estimated depletions from the Yampa Basin in Wyoming by sector <br /> <br /> Average annual <br />Sector depletions (AF) Hydrologic Basis <br />Agriculture (irrigation)' 26,905 Includes High Savery Project <br />Municipal and Industrial (M&I) 76 Consumption by towns of Baggs & Dixon <br />Exports (trans-basin diversions) 14,400 Cheyenne I & II (1995-1997 usage) <br />Evaporation' 1,202 Diked wetlands & small reservoirs <br />i TOTAL I 42,583 I I <br /> <br />'Portions of High Savery Project allocated to agriculture (6,855 AF) and evaporation (869 AF) <br /> <br />Table 12.
