The requirement of minimum flows and the actual flows are <br />both represented on the exhibit. <br /> <br />C. Turquoise lake <br /> <br />On September 30, 1982, 122,410 acre-feet of water was in storage in <br />Turquoise lake. Homestake Project filled their contracted storage space to <br />30,000 acre-feet by importing approximately 22,740 acre-feet of water <br />through the Homestake Tunnel. In addition to the Homestake imports, <br />Busk-Ivanhoe imported approximately 9,390 acre-feet of water through the <br />Carlton Tunnel throughout the year, of which 4,580 was stored for the High <br />Line Canal Company. The project imported 87,670 acre-feet of water through <br />the Charles H. Boustead Tunnel during May through September. <br /> <br />Re 1 eases through Sugar Loaf Dam were made as outl i ned in 1 ast year 's <br />Annual Operating Plan except from June 20 through August 14 when addi- <br />tional releases had to be made into Lake Fork Creek. <br /> <br />,d---/ <br />~ <br /> <br />The Mt. Elbert Powerplant was out of service for repairs and maintenance <br />from March 27 through August 25. During this period, water was released <br />from Turquoise Lake to continue the requirement for the Leadville Fish <br />Hatchery and to fill the Mt. Elbert Forebay. With the powerplant out of <br />service, all the native inflow and import water that could not be stored was <br />released into lake Fork Creek. Reservoir storage exceeded the top of <br />active conservation capacity from July 7 through July 17 and remained <br />at or above 98 percent of capacity through August 10. After a minor <br />draw down and refill in August the reservoir was operated at a <br />relatively constant elevation throughout September. Exhibits 5 and 6 <br />show the prec i pitat i on and pan evaporat i on at Turquoi se Lake. The <br />water year ended with a content of 126,790 acre-feet in storage. <br /> <br />. <br /> <br />9 <br />
