Nothing said here IS intended to imply <br />that the intense current concern m regional concepts IS precIpI- <br />tate. It is none too soon to do the advance planning. We should <br />remember that basic studies for the California Water Plan, of <br />which the present State Water Project IS the first development, <br />began three decades ago? <br /> <br />SOUTHEASTERN CALIFORNIA <br /> <br />The primary activity in southeastern California is agriculture and <br />is one of the state's most productive agricnltural areas. For example, <br />the Colorado Desert hydrographic area has an estimated 709,000 <br />irrigated acres. Imperial County, with total irrigable lands of 570,000 <br />acres, presently has 550,000 acres under irrigation. The value of all <br />farm products sold m Imperial County increased 64.8 percent be- <br />tween 1954 and 1959, more than double the state average and the total <br />value of crops in the county in 1959 was $169,324,300. <br />Under the Seven Party .Agreement for allocation of Colorado River <br />water within California, the first three priorities (comprising 3,850,- <br />000 acre-feet) are held by the agricultural areas of southeastern Cali- <br />fornia.
