<br />0037' <br /> <br />2.9 <br /> <br />~.. f <br /> <br />Alternative 6/9. Municipal/Industrial Water Sales Minimizing <br /> <br />Risk to Fish, Wildlife and Recreation <br /> <br /> <br />This alternative provided for M&I water sales which minimize risk to <br /> <br /> <br />instream and recreation values. The level of r+sk to instream and recreation <br /> <br /> <br />uses was in accordance with the hydrology of th~ Fryingpan River basin. The <br /> <br />full supply delivery schedule was used to achieve the objectives under this <br /> <br />alternative. The maximum level of water sales which could be achieved under <br /> <br /> <br />this alternative waS 45,000 acre-feet per year. Alternative 9 simply added <br /> <br /> <br />the consideration of a run-of-the-reservoir hydropower plant at Ruedi Dam. <br /> <br />The "best" condition was assumed to be the high"!st level of discharge which <br /> <br /> <br />could be sustained by the reservoir over the entire year, which was <br /> <br />Alternative 6. <br /> <br />The environmental impacts of Alternative 6/9 were moderate. Stream flows <br /> <br />were altered more than 10 percent for only five months of an average year. <br /> <br /> <br />Water volume in Ruedi Reservoir was only 3,000 acre-feet less than the c~rrent <br /> <br /> <br />condition on September 1 of the year, and drawdown averaged only six feet. <br /> <br /> <br />The reservoir had a 15 percent chance of being pelo~ 85,000 acre-feet on <br /> <br />September 1 of each year. <br /> <br /> <br />This, alternative was eliminated essentially because the constant release <br />.~ . <br /> <br />of water under a full demand schedule fails to adequately meet the demand of <br /> <br /> <br />water users, as indicated in their requests to the Bureau of Reclamation. <br /> <br />Alternative 7. <br />Minimizing Risk <br /> <br />Modified Municipal/Industrial Water Sales <br />to Wildlife and Recreation Partial Supp12 <br /> <br /> <br />This alternative encouraged the winter distribution of Ruedi Reservoir <br /> <br /> <br />water based on augmented water sales to junior water rights. Eighty percent <br /> <br />of the water shortage in the Colorado River will; occUr in the months of <br /> <br /> <br />August, September and October with the assumed f~ture demand of 433,000 acre- <br /> <br /> <br />feet. This alternative decreased the overall leyel of augmented sales by 44 <br /> <br />percent from the Alternative 2 level of sales and then imposed a 25 percent <br /> <br /> <br />reduction in the maximum water sales in the month of April through August. <br /> <br /> <br />The result was a maximum water sale of 36,700 acre-feet per year or a net <br /> <br /> <br />reduction of 48 percent in the maximum augmented sale from the sales level in <br /> <br /> <br />Alternative 2, The level of augmented sales in an average year is 16,000 <br /> <br />acre-feet. <br />
