<br />The Colorado River Aqueduct was completed in 1940. It has the capacity to deliver about <br />1.212 million acre feet per year from the Colorado River to the Southern California Coastal Plain. <br /> <br />Construction of the All American Canal and Imperial Irrigation District Diversion Dam <br />began in 1934. Water was first delivered in February 1942. Construction on the Coachella Canal <br />which serves about 85,000 acres just north of the Salton Sea began in 1938. The canal was <br />completed in 1943. <br /> <br />Davis Dam was authorized by Congress in 1943. It was not constructed until after World II. <br />The dam, which was completed in 1952, is about 67 miles south of Hoover Dam and 70 miles north <br />of Parker Dam. It impounds Lake Mohave. The primary purposes of Davis Dam are to serve as an <br />afterbay to allow the Hoover Dam hydroelectric capacity to be used as a load following or "peaking" <br />resource and to allow the United States to better manage deliveries to Mexico. Lake Mohave has a <br />capacity of about 1.7 maf, but an active capacity of only 300,000 af. <br /> <br />California Water Contracts and the Seven Party Agreement <br /> <br />In 1931, at the urging of Rec1amation, the California parties contracting for Colorado River <br />water entered into the seven party agreement.
