It should be accepted by all concerned, therefore, <br /> <br />that 14 million acre feet per year is the upper limit of the dependable <br /> <br />supply obtainable from the undep1eted or virgin flow of Colorado River <br /> <br />at Lee Ferry. <br /> <br />The upper limit of depletions of the natural or virgin flow of <br /> <br />Colorado River at Lee Ferry is thus no more than 4,000,000 acre feet <br /> <br />per year if California's existing uses are not to be curtailed under the <br /> <br />apportionment set forth in the decree recommended by the Special <br /> <br />Master to the United States Supreme Court. The resulting shortage in <br /> <br />the supply of water, required for development of the Upper Basin, is <br /> <br />almost one-half of the total supply envisioned by the Compact Commission <br /> <br />in 1922 as being available for use in that basin. <br /> <br />PROJECTS FORECLOSED <br /> <br />It is generally recognized that depletions caused by projects in <br /> <br />operation or authorized prior to 1949 for construction in the Upper <br /> <br />Basin will amount to 2,548,000 acre feet per year. This amount of <br /> <br />depletion is broken down among the States of the Upper Basin in <br /> <br />H. D. No. 364, 83rd Congress, 2nd Session, page 148, as follows: <br /> <br />Arizona <br />Colorado <br />New Mexico <br />Utah <br />Wyoming <br /> <br />11,000 acre feet per year <br />1, 591,000 acre feet per year <br />79,000 acre feet per year <br />628,000 acre feet per year <br />239,000 acre feet per year <br /> <br /> <br />There would thus remain available to the Upper Basin only about <br /> <br />1,450,000 acre feet per year for all other purposes, if California's <br /> <br />-6- <br />
