<br />~ ;'") <br />l"X) <br />...~ <br /> <br />.VATER SUPPLY <br /> <br />Water Requirement <br /> <br />The water requirement of project lands has been determined from <br /> <br />analysis of consumptive use of water based on temperature records at <br /> <br /> <br />Rifle, and from information on water used on a number of Bureau of <br /> <br />Reclamation projects of similar soils and climatic conditions on which <br /> <br />a full supply of water is now used. Consumptive use calculations, <br /> <br />taking into account expected deep percolation losses and canal losses <br /> <br />in conveyance of the water from natural stream diversion to place of <br /> <br />use, show that 3.40 acre-feet per acre annually will be required for <br /> <br />full irriga.tion. This compares favorably with the water used on other <br /> <br />Bureau of Reclamation projects under similar circurnstances. <br /> <br />Present Water Supply <br />Records of annual diversion by the Grass Valley Carull show that <br /> <br />in heavy run-off years on Rifle Creek the lands presently cropped, <br /> <br />amounting to approxil!l"lte1y 4,090 acres on Harvey Mesa below the Harvey <br /> <br />Gap Reservoir and 1,130 acres in DI"'J Elk Valley above the Harvey Gap <br /> <br />Reservoir, have a good supply of water. In dry years, however, very <br /> <br />little water is available for such lands after July 1 except that stored <br /> <br />in the Harvey Gap Reservoir. In the 7 year period 1937-19h3 inclusive <br /> <br />shortages within ideal demand are estimated to have occurred as follows: <br /> <br />Year Shortage Year Shortage <br />1937 48% 1941 11% <br />1938 8% 1942 ~ <br />1939 51% 1943 48% <br />1940 48% Average 31% <br /> <br />_. u <br />
