<br /> <br />-10- <br />The average annual virgin flow at Cameo (1931-40) was <br />2,843,500 plus 384,000 . 3,227,500 acre-feet. Subtracting the con- <br />sumptive use of 1,280,000 from the virgin flow, there was left an <br />excess of 1,947,500 acre-feet on an average to pass down the j'ain <br />Stem of the River and o~t of the State each year of this long, dry <br />period if the river basin had been fully developed. <br />C. .~ River Water SUPPJ~. <br />A study of the yield of the Blue River at Dillon, Colorado, <br />oovering the years 1931-53, together with Snake River and Ten-Ilile <br />Creek, presents some interesting results. Taking into account the <br />demands at Shoshone and at Cameo, there would have been available <br />for 'diversion at Dillon 162,000 acre-feet if storage had been <br />provided. In addition, ,there would have been sufficient yield to <br />permit storage of 100,000 acre-feet in Green f~ountain Reservoir <br />each season, and 147,000 acre-feet in this reservoir after years <br />of low runoff to refill the replacement capacity for Colorado-Big <br />Thompson Project. The City of Denver and the Federal Government <br />are presently engaged in a law suit over the rights to some of <br />this water. <br />O. Effect of Frvinqpan-Arkansas Project Depletions <br />In January of 1955, a study by'the Colorado Water <br />Conservation Board of the effect of depletions by the Fryingpan- <br />Arkansas Project on the flow of the Colorado River showed that <br />under the conditions existing in 1931-40, the driest ten years <br />on record, with Colorado's average yearly share set at <br />4It 2,3~0,000 acre-feet, there would have been 648,000 acre- <br />. <br />feet of uncommitted Colorado water.
