Of the total acreage, <br /> <br />5,102 acres receive water from irrigation districts, 7,153 acres <br /> <br />are served from pumps taking water directly from the Colorado <br /> <br />River, and 3,530 acres are served from wells. In addition, there <br /> <br />are 10,900 acres of private and State lands being irrigated without <br /> <br />benefit of contracts therefor with the Secretary of the Interior, <br /> <br />i.e., 6,740 acres served by pumps in the river, and 4,160 acres <br /> <br />irrigated from wells. A conservative average of water diversion is <br /> <br />six acre-feet of water pumped from the river or drawn from the <br /> <br />underground to irrigate each acre of land. The consumptive use of <br /> <br />water by the crops being raised would be less, probably slightly <br /> <br />more than four acre-feet per irrigated acre. Based on six acre-feet <br /> <br />measured at the pumps or wells, there would be more than 100,000 <br /> <br />acre-feet of water used on Federal lands of which only slightly over <br /> <br />21,000 acre-feet is pumped from wells. To irrigate private and <br /> <br />State lands over 38,000 acre-feet of water is pumped from the river <br /> <br />and nearly 25,000 acre-feet is taken from wells. <br /> <br />Combining these figures, it is apparent that over 160,000 acre-feet <br />
