If Colorado has to curtail uses to comply with <br />the Lee Ferry delivery obligations of the Colorado River <br />Compact, "the diversion for the benefit of the eastern <br />slope shall be discontinued in advance of any western <br />slope appropriations." <br /> <br />Senate Document 80 states that the present irrigated <br />acreage along the Colorado River between Palisades and the <br />Utah line is 70,600 acres, and that there is an additional <br />arable acreage of 32,800. The critical points are Shoshone <br />where 1250 c.f.s. is required, and at the head of the Grand <br />Valley where an estimated 1800 c.f.s. is required. The <br />document fu~her states that in detel~ining the effect of <br />the Colorado-Big Thompson transmountain diversion on the <br />west slope, the following developments were recognized: <br /> <br />1. Full irrigation of 276,000 acres along the Colorado <br />River and tributaries above Palisades. <br /> <br />2., Full development of Moffat Tunnel diversion from <br />Fraser River and tributaries, Jones Pass diversion from <br />Williams River, and Independence Pass diversion from Roaring <br />Fork. <br /> <br />It should be noted that the proposed Blue River- <br />South Platte diversion, either by the City of Denver alone <br />or as being studied by the Bureau of Reclamation was not <br />taken into consideration. <br /> <br />In the descriptive portion of the document it is stated <br />that Green Mountain will have an irrigation outlet capacity <br />of 1,000 c.f.s. and a power outlet capacity of 1,500 c.f.s. <br />The following quotation is taken directly from Senate Docu- <br />ment 80: <br /> <br />"From the water-supply studies it was found, <br />assuming that full development had taken place <br />in the Colorado River Basin and that the Big <br />Thompson project had been in operation the last <br />35 years, that in the year 1931, the lowest year <br />of dependable run-off record, the Colorado Basin <br />users above Glenwood Springs would have been shorted <br />37,000 acre-feet for irrigation use and the Public <br />Service Co. would have been shorted 16,000 acre- <br /> <br />"" <br /> <br />~s"} <br />,< <br />
