This minimum 3 <br />requirement ~or nonna1 diversion season is as follows: April - 100 ft Is, <br />May - 150 ft Is, June - 200 ft3/s, July - 100 ft3/s, and August- <br />75 ft3/s, or the natural flow, whichever is less. During water year <br />1982, the flow was less than the set rates on two occasions. When this <br />situation oc=s the diversions into the Fryingpan-Arkansas Project <br />system are decreased or in some cases shut down with only the Hunter <br />Creek system, which drains into the lbaring Fork River, allowed to <br />continue diverting water to Boustead Tunnel. <br /> <br />Exhibit 2 shows the flows at the Thornasville river gaging station and <br />the minimum flow requirements. <br /> <br />Project Diversions <br /> <br />The water year 1982 outlook used a project diversion of 67,900 acre- <br />feet, the historical average, for the rrost probable runoff condition. <br />The February 1, March 1, April 1 and May 1 forecasts, based on Soil <br />Conservation Service STl!:M course data, projected diversions of 121,200 <br />acre-feet, 82,700 acre-feet, 85,700 acre-feet, and 85,600 acre-feet, <br />respectively. The actual diversion was 75,210 acre-feet, as measured <br />at the outlet portal of3Charles H. Boustead Tunnel. The Il'aXimum mean <br />daily :import was 909 ft Is on June 29, 1982, with a maximum instantan- <br />eous peak of 960 ft Is on <J\IDe 28. A senior call was not made on the <br />Colorado River, therefore, no releases from Ruedi Reservoir were neces- <br />sary to replace project diversions.
