<br />2.GS8 <br /> <br />are anticipated to be around 49,200 acre-feet under most probable conditions <br />during this water year. <br /> <br />D. Turouoise Lake <br /> <br />Inflow to Turquoise Lake for WY 199~ will be from four sources: Busk- <br />Ivanhoe imports; Fryingpan-Arkansas Prpject imports; Homestake Project <br />imports; and native flow of Lake Fork. : Estimates of inflow from Busk- <br />Ivanhoe and native Lake Fork were made using historical records and <br />probability analysis. Project water imports are estimated to be <br />49,200 acre-feet. Homestake Project does not pl an to import any water <br />stored in Homestake Reservoir during wa~er year 1991. <br /> <br />The planned operation of Turquoise Lake for water year 1991 will be to <br />maintain the reservoir as near capaci~Y as possible by the storage of <br />Project imports and Busk-Ivanhoe imports. <br /> <br />The Pueblo Board of Water Works and the iCity of Aurora each own one-half <br />of the Busk-Ivanhoe imports. The Board's water will either be bypassed <br />through Turquoise Lake for storage in Clear Creek Reservoir (by exchange <br />with native water) or for direct flow usage at Pueblo or be stored in their <br />long-term storage space in Turquoise Lake. The City of Aurora water will <br />be stored in their long-term storage sp~ce. <br /> <br />The city of Colorado Springs can store all of the native inflow to Turquoise <br />Lake when they are in priority (maximum! of 17,416 acre-feet). <br /> <br />Water rel eased from Turquoi se Lake i nexcess of either i nstream minimum <br />flow or flow to meet downstream senior rights along Lake Fork will be <br />diverted into the Mt. Elbert Conduit. The water will flow through Mt. <br />Elbert Powerplant and then be released to the Arkansas River from Twin Lakes <br />via Lake Creek. <br /> <br />The minimum release into Lake Fork is IS!ft3/s, or natural inflow, whichever <br />is less. . <br /> <br />Table 16 and exhibit 22 show the proposed operation of Turquoise Lake in <br />WY 1991. <br /> <br />E. Federal Fish Hatcherv and Hal~moon Creek Diversion <br /> <br />The Federal Fish Hatchery near Leadville, Colorado, will be supplied <br />flow-through Project water at a rate oflup to 6.7 ft3/s as has been done in <br />past years. This flow is released from Turquoise Lake through Mt. Elbert <br />Conduit to the fish hatchery and then into the Arkansas River. The flow is <br />later stored, less appropriate transit losses, in Pueblo Reservoir. <br /> <br />The planned operation of Halfmoon diversion is to divert all the flow in <br />Halfmoon Creek, to the maximum diversion capacity of 150 ft3/s, which is in <br />excess of the downstream call on Halfmoon Creek or the instream minimum <br />flow. At times, this diversion flow m~y be restricted due to operational <br />releases from Turquoise Lake into Mt. !Elbert conduit. The diverted flow <br />plus the release will pass through Mt. iElbert Powerplant and will then be <br />released to the Arkansas River via Lake Creek. <br /> <br />32 <br /> <br />I <br />I <br />t <br />t <br />t <br />t <br />I <br />I <br />t <br />t <br />t <br />I <br />I <br />t <br />, <br />t <br />I <br />I <br />, <br />
