per year. A portion of the diversions of Colorado River water through the Metropolitan Water District Aqueduct has been used to recharge depleted ground-water storage in basins along the coastal area of southern California. The Metropolitan Water District of Southern California, which serves most of the cities of southern California, foresaw that water supplies available from the Colorado River and other local sources would not be adequate for future demands. Accordingly, it signed a contract with the State of California in 1960 for the future delivery of up to 1,500,000 acre-feet of water per year. This water would be delivered through the facilities of the California Water Plan, estimated at that time to meet the needs of southern California until about 1990. This estimate was based on the premise that the present rate of diversion from the Colorado River would continue. The California State Water Plan is a comprehensive development to efficiently utilize the surplus water resources of northern California to the benefit of the entire State. Two legislative acts late in 1960 made possible the implementation of this plan: the congressional authorization of the San Luis Project and a California State referendum, which authorized State issuance of a $1.75 billion bond issue to finance the State's proposed project works. The California State water plan anticipates delivering surplus water from northern California through an aqueduct along the west side of the San Joaquin Valley southward to the vicinity of Bakersfield where it would be pumped across the Tehachapi Mountains and delivered to areas in southern California. The State of California and the Bureau of Reclamation are fully cooperating in the operational and financial aspects of joint-use facilities which will benefit both the State project and the Federal project water consumers. These facilities are anticipated to be constructed and in operation by the year 1971. The City of Los Angeles is also currently planning a new addition to its Owens Valley aqueduct system which will increase the existing capacity of the aqueduct. Its plan is to have the first section of the new aqueduct in operation by 1965, and the balance by 1968. At the present time limited quantities of sewage effluent are being utilized for ground-water recharge in the coastal areas of southern California. This water source also is being used to combat salt-water intrusion that is occurring in fresh-water aquifers along the coast. II-8Epson Perfection 4870 Photo, 400 dpi, 8 bit, 14,131,200 byte
