<br />.... ODOllSS' <br /> <br />- 4 - <br /> <br />The above computations of consumptive use are based on the <br />principle of sharing of shortages among the New Mexico uses. <br />If the Navajo Project is a preferential use, there would be no <br />water for other New Mexico project demands in two years of a <br /> <br />water supply period such as 1928-1956. <br />Condition B. The assumption for this analysis was that the <br />full Pine River project of 69,000 acres, as authorized, be <br />developed, together with the authorized Weminuche Pass diversion. <br />Studies by the Water Conservation Board indicate that this <br />diversion would average 16,300 acre feet annually, and that addi- <br />tional depletions on the Pine River in Colorado qould average <br />60,800 acre feet annually. The natural flow of the San Juan <br />River near Blanco was reconstructed so that a simulated reservoir <br /> <br />operation at Vallecito reservoir for the total project would be <br /> <br />imposed. <br /> <br />Under this assumption shortages for the New Mexico uses <br />were indicated for the years 1951, 1954, 1955 and 1956 of the <br />study period, as shown in Column 11 of the study. When these <br />shortages are modified for evaporation loss and Citizens Ditch <br />diversions on the same basis as for Condition A, the shortages <br />for these four years of the study period would be 179,000, 291,000, <br />373,000 and 396,000 acre feet respectively, as shown in Column 13. <br />Resulting diversions from Navajo Reservoir would be 76, 61, 51 and <br />48 percent of the ideal diversion demand of 755,000 acre feet. <br /> <br />,t <br />,C <br />'. <br /> <br />. <br />
