<br />i: <br /> <br />, . <br />002000 <br /> <br />occur in several years. <br /> <br />Water operation studies using the demand of Criteria No.2 <br />indicate shortages in reservoir supply in 4 years of the 29-year <br />period. The following table shows such shortages with no new use <br />in Colorado and indicates the range of shortages with assumed 20,000, <br />50,000 and 100,000 acre feet of new depletion in Colorado. <br /> <br />CRITERIA NO.2 <br /> <br />Shortaqes in New Mexico Normal Demand on ,Navaio Reservoir ' <br /> <br />" Authorized <br />Proje'cts <br />in Colorado <br />Shortaqe Percent <br />1000 AF <br /> <br />New Colorado Uses <br /> <br />Year <br /> <br />20.000 <br />Shortaqe <br />1000 AF <br /> <br />Ac ;Ft. 50,; 000 Ac.Ft. <br />Percent Shortaqe Percent <br />1000 AF <br /> <br />100.000 Ac.Ft. <br />Shortaqe Percent <br />1000 AF <br /> <br />1947 8 1 158 20 354 45 <br />1950 121 15 <br />1951 308 40 453 57 573 72 652 82 <br />1953 57 7 157 20 <br />1954 366 46 382 48 416 52 466 59 <br />1955 445 56 465 59 495 62 545 69 <br />1956 425 54 445 56 475 60 525 66 <br /> <br />Considering only existing uses in Colorado, the demand <br />schedule of Criteria No. 2 would result in shortages in reservoir sup- <br />ply, in the years 1955 and 1956. These would each be in the amount of <br />375,000 acre feet or 47 percent. <br />It should be recognized that the water demand figures for <br />New Mexico used in the above analyses were taken either from esti- <br /> <br />r <br />h <br /> <br />f <br /> <br />mates in reports of Federal agencies or from estimates in letters <br /> <br />of New Mexico State Engineer Reynolds. It is probable that the actual <br />demands after development may exceed these estimates. In the case <br />of the Navajo Project in particular, the diversion demand figure of <br />508',000 acre feet was estimated as the irrigation diversion requirement: <br /> <br />-10- <br /> <br />.i.. ~ <br /> <br />t,,;: <br />, <:, ,:_~':~,'~:L~~i.;, ,~~, ,'. <br /> <br />,,'>'.. :,., <br />
