<br />2000 <br /> <br />5.430 <br /> <br />6.180 <br /> <br /> <br />~ <br />00 <br />-J <br />'-.n <br /> <br />o[ the water deliveries to Mexico, or 750,000 acre-,feet annually, <br /> <br />the amount ,ol'vailable for consumptive use annually in the Upper <br /> <br />Basin would be 5.8 m.a.f. <br /> <br />In connection with the Colorado River Basin Project, the <br /> <br />Bureau of Reclamation h3S previ.ously projected that con-stJlUptive <br /> <br />use of Colorado River Bosin water by the Upper Basin States would <br /> <br />reach 5.8 m. a. f. in the year 2030. Tile Bureau recognized that <br /> <br />the potential [or use of water by the Upper Basin States is much <br /> <br />greater and could occur at a muel} earlier date. Tile projections <br /> <br />made were judgment values based on a limited water supply. With <br /> <br />augmentation of the Colorado River and consequent assurance that <br /> <br />the Upper Basin would not be required to contribute to Mexican <br /> <br />water deliveries, it could be expected that expansion of Upper <br /> <br />Basin depletions would be faster and to a higher ceiling. To <br /> <br />rc~lect tilis, new projections were made of Upper Basin depletions <br /> <br />for this report which are compared with the projections of the <br /> <br />1967 Summary Report in the following tabulation: <br /> <br />Year <br /> <br />Annual Upper Basin Depletions (M.A.F.) <br />1967 Summary Report This Report <br /> <br />19)5 <br /> <br />4.220 <br /> <br />4.220 <br /> <br />1990 <br /> <br />5.100 <br /> <br />5.475 <br /> <br />2030 <br /> <br />5.800 <br /> <br />6.550 <br /> <br />Should :Upper Basin depletions occur at a faster ratc tItan projected, <br /> <br />it would be necessary to bring the ini.tial units of the Dugmenting <br /> <br />9 <br />
