<br />. <br /> <br />29 <br /> <br />.. <br /> <br />'g. .... .. <br /> <br />The most likely material for lining the Towaoc Canal would be medium <br /> <br />:extured material obtained from the canal excavation or from nearby barrow areas. <br />- 3 2 <br />rhis material is assumed to have a value of C=0.32 ft 1ft Iday. Depending on <br /> <br />:he availability of suitable material for compacted earth lining, it may be <br /> <br />~ssible to maintain the canal such that the 14-year average seepage rate <br /> <br />~ed here is not excessively exceeded. Conservative estimates of seepage rates <br /> <br />. <br />)ver the life of the 42-mile long Towaoc Canal ~an significantly affect the <br /> <br />irrigation project to be served. Evaporation losses are considered part <br /> <br />)f the seepage losses. <br /> <br />1.8.3 Operational Losses <br /> <br />Operational losses are assumed to be 5% of the gross diversion requirements. <br />'" <br />.... ~ <br /> <br />t.9 Diversion Requirements <br /> <br />Table 2.9 summarizes the diversion requirements to irrigate an acre of <br /> <br />lrrigable land on the Ute Mountain Ute Indian Reservation. An area totaling <br /> <br />. <br /> <br />r,SOO acres has been planned for service from the Dolores Project. Present <br /> <br />Istimates show that this area has-been selected from 10,003 acres of land that <br /> <br />:an potentially be irrigated. <br /> <br />" <br /> <br />.Netdiversion requirements were estimated for two alternative locations <br /> <br />~ere irrigation water can be measured. One is at the McPhee Reservoir Outlet <br /> <br />:Dolores Tunnel) and the other within the Indian Reservation boundary at <br /> <br />~waoc. The difference between these alternatives is seepage loss within <br /> <br /> <br />he 27-mile reach of the Towaoc Canal between the two locations. The Towaoc <br /> <br />anal extends another IS miles within the Indian Reservation from Towaoc. <br /> <br />etails of the computational procedure were in the preceding parts of this <br /> <br />1apter. <br /> <br />The weighted consumptive use, totaling 2.34 per acre per season involves <br /> <br /> <br />cropping pattern composed of alfalfa, small grain, beans, pasture, and corn <br /> <br />I...." ..,~.;...1..... _.c II!"n <br /> <br />..., <br /> <br />..^ <br /> <br />.^ <br /> <br />." <br />
