This reservoir will be built in <br />conjunction with the Mulberry D <br />interceptor lateral. receiving its surplus <br />water from the Vail Main Spill. <br /> <br />Other projects under this agreement <br />include various regulatory reservoirs, <br />lateral interceptors, canal lining, 12- <br />hour deliveries, non-leak gates, system <br />automation and on-farm irrigation <br />management. <br /> <br />Flow into 110 System <br /> <br />IlD is the largest irrigation district in <br />the nation. The 82-mile-Iong All- <br />American Canal delivers approximately <br />2.7 million acre-feet of Colorado River <br />water annually to the Imperial Valley. <br />Imperial County ranks among the top <br />ten agricultural counties in the nation. <br /> <br />Acre-feet <br />1994 .................................. 2,695,981 <br />1993 .........................,..;..... 2,434,988 <br />1992 .................................. 2,675,720. <br />1991 ................................:.. 2,985,177 <br />1990. .................................. 3,050.,0.0.8 <br />1989.................................. 3,0.04,888 <br />1988 .................................. 2,943,868 <br />1987.................................. 2,758,681 <br /> <br />Water <br /> <br />Imperial Irrigation District <br />Service Area <br /> <br />Area Served <br /> <br />.::_~ <br /> <br />Fano accounts ................................. <br /> <br />QwQ~r-QpenlteQ fArm Q~~Qunts Itlll,l <br />Tenant-operated farm accounts ........ <br />Average acreage offano accounts ... <br /> <br />6,300 <br />2,616 <br />3,684 <br />76.65 <br /> <br /> <br />COLOIltADO IllIVE" \~ <br /> <br />Water Customers <br /> <br />1I.~i.. <br />...",;; <br />
