(. ~'.. ~1 '1: <br /> <br />reservation both along the river bottoms and on benches north of the river for <br /> <br /> <br />about 12 miles above the confluence of the Green and White Rivers. (See figure 16.) <br /> <br />Bingham Engineers of Salt Lake City, Utah, under contract conducted field <br /> <br /> <br />explorations and designed a distribution system to serve the area. Their work is <br /> <br /> <br />found in the report "White River Indian Irrigation Project" with Appendices A <br /> <br />and B dated April 1978. <br /> <br />If the Ute Indian Tribe were to develop its White River irrigation <br /> <br /> <br />potential without an upstream reservoir, and if it were able to create a dry <br /> <br /> <br />diversion dam, and if no further Colorado water resource developments occurred <br /> <br /> <br />on White River in the future these lands would still suffer shortages. In 1934, <br /> <br /> <br />1963, 1966 and 1977 significant July shortages would occur. In 15 other years of <br /> <br /> <br />the 48 year study period (1931-1978) minor shortages would be experienced for <br /> <br /> <br />short periods within the month of July when the flow of the river drops below <br /> <br />220 cis. <br /> <br />A diversion dam (yet to be designed) will be constructed on White River <br /> <br /> <br />in Section 18, T9S, R22E, SLM by the Ute -Indian Tribe possibly in conjunction <br /> <br /> <br />with Tosco Corporation as mentioned earlier. <br /> <br />Assuming a 4.0 acre-feet per acre duty the diversion requirement will be <br /> <br />51,000 acre-feet annually. Approximately one-half of the land will be flood <br /> <br /> <br />irrigated and one-half will be sprinkle irrigated. Alfalfa, corn and small grains <br /> <br /> <br />will be the principal crops grown. The soils are genera~ly in excess of 5 feet <br /> <br /> <br />deep and are mostly of a sandy loam type. Drainage may be required in some <br /> <br /> <br />areas to prevent undesirable accumulations of salt. Allowing 50 cfs for fish <br /> <br /> <br />bypass beyond the diversion dam a July flow of 270 cfs will be required to meet <br /> <br /> <br />demands. Power releases consisting of part storage and part direct flows at <br /> <br />White River Dam ranging from a minimum of 250 cfs to a maximum of 600 cfs will <br /> <br /> <br />insure that peak irrigation demands will be met with the project. <br /> <br />Irrigation water will be pumped from the diversion canal at thirteen <br /> <br /> <br />locations to serve the higher bench lands. The two larger pumping plants will <br /> <br /> <br />have 60 and 80 cfs capacities. With exception of an 18 cfs plant on the White <br /> <br /> <br />River, the remaining plants will be considerably smaller in the 1 to 5 cfs range. <br /> <br />Two storage reservoirs of 3,000 acre-feet and 570 acre-feet capacity will <br /> <br /> <br />be constructed above the bench areas. The growing season averages 160 days. <br /> <br /> <br />The water quality is adequate for irrigation use, however, under present direct <br /> <br />- 29 - <br /> <br />
