As inflow was still <br />small, outflow was reduced to near 50 c.f.s. <br /> <br />Minimum storage, 53,468 acre-feet, was reached on April lO. <br /> <br />Based on the May 1 snow forecast of the May-June inflow, the uniform <br />outflow from Ruedi Reservoir should have averaged about 300 c.f.s. <br />On May 1, Ruedi Reservoir had a content of 54,l83 acre-feet. At <br />that time the inflow was averaging about l30 c.f.s. In order not <br />to draw the reservoir water surface below the elevation of the <br />bottom of the boat ramps, the outflow in May was started at l88 <br />c.f.s. By the end of May the outflow was 437 c.f.s. During June <br />the outflow was held near the forecast 300 c.f.s. <br /> <br />. <br /> <br />On July 1, 1973, Ruedi Reservoir storage was 99,68l acre-feet. On <br />July 16 the maximum storage of 103,934 acre-feet was reached. The <br />water surface elevatIon at this time was 7767.56 or l.56 feet above <br />the spillway crest. The reservoir was then drawn down to a point <br />two feet below the spillway crest and held at this stage. <br /> <br />August releases were to be no less than l50 c.f.s. In August 1973, <br />inflow to Ruedi Reservoir dropped considerably below 150 c.f.s., <br />resul tine in a further drawdown of the reservoir. <br /> <br />On October 1, 1973, there was 96,260 acre-feet of storage in Ruedi <br />Reservoir. <br /> <br />Table 1 and Exhibit 3 show the 1973 operation of Ruedi Reservoir. <br /> <br />Colle:c!_ion SY!'tem <br /> <br />Project diversions began on May 11 and concluded on August 18 when <br />fish bypass requirements forced discontinuance. During this period, <br />36,825 acre-feet was imported and stored. A breakdown of the <br />source of this imported water is as follows: from Sawyer Gulch, <br />6 percent; from Chapman Gulch, l8 percent; from South Fork, 31 <br />percent, and from the main stem of the Fryingpan River, 45 percent. <br />The fish bypass requirements as used in the 1973 operation were as <br />follows: <br /> <br />7 <br />
