<br />..... <br />C',J <br />..... <br />.-; <br />c <br /> <br />Inasmuch as bank storage in Lake Pleasant was not con- <br /> <br />sidered'by the Geological Survey in computing the flow of the <br /> <br />Agua Fria River at Lake Pleasant Dam, consideration was not <br /> <br />given to changes in bank storage in Lake Pleasant. <br /> <br />Average annual changes in surface and bank storage in <br /> <br />reservoirs in the Lower Colorado River Basin for the 1946-1951 <br /> <br />period are listed in Table MS 11. <br /> <br />6. Transbasin Export Diversions <br />Export diversions of water from the Lower Colorado River <br /> <br />system for use outside of the natural drainage area of the <br /> <br />Lower Colorado River were continued by the same diversion systems <br /> <br />discussed in the report for the 1914-1945 period, except the <br /> <br />Alamo Canal. The Alamo Canal system has not been used for <br /> <br />deliveries to California since February 1942. <br /> <br />It ~ms estimated that average annual diversions of 1,500 <br /> <br />acre-feet for the 1946-1951 period were made from the headwaters <br /> <br />of the Virgin River system by the Newcastle Project in Utah. <br /> <br />Records of annual export diversions by the Colorado River Aqueduct <br /> <br />and the All-American Canal were obtained from Geological Survey <br /> <br />water-supply papers. Transbasin exports are summarized in the <br /> <br />following tabulation: <br /> <br />Diversion <br /> <br />Export <br />Stream <br />-- <br /> <br />1946-1951 Average <br />Annual Export in <br />state Acre-Feet <br /> <br />Ne\fcastle Project <br /> <br />Virgin <br /> <br />Utah 1,500 <br /> <br />Colorado River Aqueduct <br /> <br />Colorado <br /> <br />California 150,200 <br /> <br />All-American Canal <br /> <br />Colorado <br /> <br />California 3,137,800 <br /> <br />Total <br /> <br />3,289,500 <br />
