<br />on3~ <br /> <br />. <br /> <br />Turquoise Lake <br /> <br />Inflow to the lake for water year 1971 will be from four sources: <br />Homestake project imports, Busk-Ivanhoe imports, Frying,pan- <br />Arkansas project imports, and native flow of Lake Fork Creek. <br />Estimates of this inflow from Busk-Ivanhoe imports and native Lake <br />'Fork Creek flow were made by use of historical records and probability <br />analysis. The 10, 50, and 90 percent chance values were obtained from <br />the probability curves shown on exhibits 1 and 2 and are considered <br />to represent the reasonable minimum, most probable, and reasonable <br />maximum inflows, respectively. Monthly distribution of these values <br />was made in accordance with historical records. However, the <br />imports by the Homestake project were determined from factors <br />other than runoff. Fryingpan-Arkansas project imports for the three <br />conditions are derived from exhibit 2, discussed above. <br /> <br />Minimum Required Reservoir Releases <br /> <br />Ruedi Reservoir <br /> <br />. <br /> <br />The fish bypass, not to exceed the stream inflow, is 39 c. f. s. for the <br />months of November through April, and 110 c. f. s. for May through <br />October. At the request of State and Federal fish and wildlife interests, <br />the fish bypass for the period October 1 through November 15 will be <br />100 c. f. s. to facilitate the brown trout hatch. At the request of <br />western slope interests, August bypass will be at a minimum of <br />150 c. f. s. <br /> <br />Turquoise Lake <br /> <br />When the project g'oes into full operation, or when Pueblo Reservoir is <br />able to store any upstream releases, fish releases are to be maintained <br />at 10 c. f. s. for October and 3 c. f. s. for November through April, or <br />natural inflow to the reservoir, whichever is lesser. Irrigation releases <br />are estimated to be sufficient for fish flow during the irrigation season. <br />During the construction period, this criteria will be followed insofar as <br />is practical without the loss of project water downstream. <br /> <br />. <br /> <br />9 <br />
