<br />. . <br /> <br />loading of the Colorado River. Using operational data from 1974, <br /> <br /> <br />Bookman-Edmonston made an independent analysis of irrigation and <br /> <br /> <br />drainage in the District. It was concluded that the river water <br /> <br />diverted by the District contained 945,000 tons of salt, and that <br /> <br /> <br />measured return flows to the river plus net subsurface outflow to <br /> <br />the river contained 1,097,000 tons of salt. The difference of 152,000 <br /> <br /> <br />tons constituted the net salt discharge from the district. <br /> <br />Bookman-Edmonston divided the irrigated flood plain land of the <br /> <br /> <br />District into 7 subareas and made water and salt budget analyses <br /> <br /> <br />for each. The effect of irrigation on the Palo Verde Mesa was also <br /> <br /> <br />considered. The subareas are shown on Map 1224-300-164, PVID hydrologic <br /> <br /> <br />subareas. The net salt discharge from each was estimated to be: <br /> <br />Palo Verde 144,000 <br />Rannell s 43,000 <br />South End 35,000 <br />Lower Borrow Pit 22,000 <br />West side 13 , 000 <br />Central -22,000 <br />East si de -57,000 <br />Subtotal for flood plain 178,000 <br />Pa 10 Verde Mesa -26,000 <br />Total for District 152,000 <br /> 0029 9 <br /> <br />12 <br />
