<br />. <br /> <br />diversions and returns must be measured. Under the present state of the <br /> <br /> <br />art, we are limited basically to measurement of surface flows. While <br /> <br /> <br />preliminary studies to date have been based largely on measured diversions <br /> <br />and measured returns, rather than on theoretical consumptive use <br /> <br />computations, some adjustments relating to consumptive use and return <br /> <br />flow credits have been made, as described in later parll4!1'aphs. Certain <br /> <br /> <br />assumptions also were made concernins timing and buildup in vater use <br /> <br /> <br />fro. present levels to ultimate full development, and potential additional <br /> <br />savings of vater through conservation measures. The studies are based on <br /> <br />demands associated with annual consumptive use of the 7,500,000 acre-feet <br /> <br /> <br />. of water allocated to the three States (4.4 maf to California, 2.8 maf to <br /> <br /> <br />Arizona, and .3 maf to Nevada) and the delivery of 1,500,000 acre-feet to <br /> <br /> <br />Mexico pursuant to the Febru.ary 3. 1944, Treaty. <br /> <br />Whether the computations hereinafter described are logical, Justifiable, <br /> <br /> <br />supportable, or in the final analysis, acceptable, is open for discussion. <br /> <br /> <br />Perhaps different or additional adJustments in return flow credits may <br /> <br /> <br />be worked out and agreed upon. The principal point to be brought out <br /> <br /> <br />here is that there is a significant gap between total consumptive use <br /> <br />&8 determined on a purely measured diversions less measured returns basis, <br /> <br />and total consumptive use as may be determined on a purely theoretical <br /> <br />. <br /> <br />2 <br />
