Colorado described Upper Basin <br />consumption as of 1922 at 2,500,000 acre-:feet of water and <br />estimated that future water requirements in the Upper Basin, <br />including transmountaindiversions, would equalS, 000, 000 acre-feet <br />of water. See, Hoover Dam Documents, p. AS3.. On the basis of a <br />projection of 7,500,000 acre-feet of water to satisfy the Upper <br />Basin, the allocations in the Compact were negotiated. Of course, <br />water supply and Mexican treaty obligations. have reduced this <br />planned Upper Basin allocation. But, nevertheless, when Reservoir <br />evaporations are not taken into account, the Upper Basin has never <br />exceeded 3,700,000 acre-feet in actual depletions. That is, when <br />viewed from 1992, the projected 1922 Compact depletions for the <br />Upper Basin are off by 70% <br /> <br />III. Lower Basin Federal policies Have Secured Full 1922 Compact <br />Depletions. <br /> <br />As noted above, the principal motivation for the 1922 Colorado <br />Compact was to set aside the potentially divisive influence of the <br />doctrine of prior appropriation as it related .to equitable <br />apportionments in the Colorado River, and create a common ground so <br />that upper Basin and Lower Basin states could together lobby <br />Congress for a series of federal dams and irrigation projects on <br /> <br />5 <br /> <br />I <br />
