The following minimum bypass requirements at the various diversion points were used during the 1990 operation: Diversion Doint Minimum bypass reauirement (ft'/s) 12 6 3 o o 2 1 1 o 2 12 5 4 2 1 o Fryingpan River South Fork Chapman Gulch Sawyer Lake Creek Li ly Pad Creek Ivanhoe Creek Middle Cunningham Creek North Cunningham Creek South Cunningham Creek Mormon Creek Hunter Creek Midway Creek No Name Creek Carter Creek North Fork Creek Granite Creek In addition to the minimum bypass requirements at each of these sites, a minimum flow requirement must be met on the Fryingpan River at Thomasville River gaging station as specified in the Operating Principles. This minimum requirement is as follows: April - 100 ft3/s, May - 150 ft3/s, June - 200 ft3/s, July - 100 ft3/s, August - 75 ft3/s, and September - 70 ft3/s or the natural flow, whichever is less. When it appears that these flows will not be met, the diversions into the Project system are decreased or stopped, whichever is necessary to meet the bypass requirements. The Hunter Creek System, which drains into the Roaring Fork River, can continue diverting water into Boustead Tunnel during these times. Exhibit 4 shows the daily flows at the Thomasville River gaging station and the average daily minimum flow requirements during the period of diversions from the Fryingpan River. C. Proiect Diversions The water year 1990 outlook (table 14, AOP, WY 1989-1990) used a projected Project diversion of 36,200 acre-feet for the reasonable minimum runoff condition. The March 1, April 1, and May 1 forecasts, based on Soil Conservation Service snow course data, projected available most probable diversions of 38,660 acre-feet, 32,400 acre-feet, and 41,600 acre-feet, respectively. 15
