0010~g . . 4. That,_Ln dccord W1th a 1951 determination qy the Secretary of Interior, releases to the Colorado River below Granby Reservoir and Willow Creek are made under the following schedule: Granby Reservoir May, June and July - 75 cfs release August - 40 cfs release All other months - 20 cfs release vIillo" Creek Reservoir Outflow equal to inflow up to a maximum release of 32 cfs for irrigation requirements during the months of July through October. All other months - 7 cfs release Daily flows. of the Colorado iQ.ver at Glemvood Springs (Shoshone Po",er Plant) Here corrected for a potential additional depletion of the river b.Y complete development of Denver's diversion system through Jones Pass and Moffat Tunnel. Colorado-Big Thompson was operated by combining the inflows of the Colorado River above Granby and Willo", Creek, then deducting irrigation and fish releases in accor- dance with schedule. The remaining quantity, or the net amount of water storable or divertible by the project, was then deducted from the flow of the Colorado at Glen",ood. Com~ined flows of the Blue River, Snake and ~en-Mlle,Creek at Dillon gives, on a daily basis, the total flow from ",hich Denver might divert up to its maximum decreed quantity of 788 cfs. On any day that the flo", of the Colorado River at Glenwood, corrected for Jones Pass, Moffat Tunnel and Colorado-Big Thompson diversions, exceeded 1450 cfs, it ",as assumed that Denver could take such flow as ",ould not decrease the stream below 1450 at Shoshone. Similarly, on days ",hen the Colorado River flow at Shoshone was less than 1450 cis, the analysis assumed cessation of Denver diversions. , -6-
