<br />" u4~1 <br />1 c. Project Diversions <br /> <br />The water year 1985 outlook used a Project diversion of <br />71,300 aere-feet for the most probable'runoff eondition. The March I, <br />April I, and May 1 forecasts, based on Soil Conservation Service snow <br />course data, projected diversions of 60,200 acre-feet, 69,000 acre-feet, <br />and 75,700 acre-feet, respeetively. ' ' <br /> <br />The actual diversion from May through September was 71,090 acre-feet as <br />measured at the outlet portal of Bous~ead Tunnel. The maximum mean <br />daily import through Boustead Tunnel waS 942 cubie feet per seeond on <br />June 8, 1985, with a maximum instantaneous peak of 963 cubic feet per <br />seeond. A senior call was not made on the Colorado River during 1985; <br />therefore, no re 1 eases from Rued i Reservoi r were necessary to rep 1 ace <br />Project diversions. ' <br /> <br />The yearly total imports, the water used for Twin Lakes Reservoir and <br />Cana 1 Company exchange, and the aecumu 1 ated imperts to the Ark ansas <br />River are shown on table 3. The 14 years of accumulated imports total <br />712,300 acre-feet for an average of 50,860 acre-feet per year. A plot <br />of the Boustead Tunnel imports is shown on exhibit 5. <br /> <br />The discharge records for all diversions in water year 1985 are shown in <br />appendix A. <br /> <br />D. Twin Lakes Exchange <br /> <br />On October I, the Twin Lakes Reservoir and Cana'l Company (Company) <br />began bypassing water into the Roaring Fork River drainage in exchange <br />for water in Twin Lakes. The exchange followed the operating criteria <br />as shown in appendix B. The total amount of the exchange at Twin Lakes <br />was 1,714.95 acre-feet. The Company' 5 account in Twi n Lakes was at <br />maximum storage during part of the run;off season and few demands the <br />rest of the runoff season allowed gre~ter than required flows to be <br />bypassed at Linco ln Gu 1 ch and Roaring Work. When these cond it ions of <br />additional bypass exist, the Company does not receive credit for water <br />being bypassed into the Roaring Fork System. The monthly summary of the <br />exchange is also shown in appendix B along with plots of the daily <br />flows. <br /> <br />. <br /> <br />. <br /> <br />E. Turquoise Lake <br /> <br />On September 3D, 1984, 127,740 acre-feet of water were in storage <br />in Turquoise Lake. Homestake projec~ maintained their storage at <br />approximately 29,000 acre-feet by impor:ting approximately 10,260 aere- <br />feet of water through the Homestake, Tunnel. In addition to the <br />Homestake imports, Busk-Ivanhoe imported approximately 2,700 aere-feet <br />of water through the Carlton Tunnel throughout the year and 1,040 aere- <br />feet of water through Bous tead Tunnel duri ng June, Ju ly, and Aug~s t. <br />Of the tota 1 3,740 acre-feet, 2,320 acre-feet was stored for the <br /> <br />. <br /> <br />6 <br />
