<br />'lGo3 <br /> <br />. <br /> <br />The mlnlmum release into lake Fork is '15 cubic feet per second, or <br />natural inflow, whichever is less. <br /> <br />Table 11 and exhibit 19 show the proposed operation of Turquoise lake in <br />water year 1986. <br /> <br />E. Federal Fish Hatehery and Halfmoon Creek Diversion <br /> <br />The Federal Fish Hatchery near ~eadville, Colorado, will be <br />suppl ied flow-throu9h Project water at a rate of up to 6.7 cubic feet <br />per second as has been done in pas t yeats. Thi s flow is released from <br />Turqueise lake through Mt. Elbert Conduit to the fish hatehery and then <br />into the Arkansas River. The flow is later stored, less appropriate <br />transit losses, in Pueblo Reservoir. <br /> <br />The planned operation of Halfmoon diversion is to divert all the flow in <br />Ha 1 fmoon Creek, to the max imum di vers i on capac i ty of 150 cubi c feet per <br />second, which is in exeess of the downstream eall on Halfmoon Creek or <br />the instream minimum flow. The diverted flow will pass through <br />Mt. Elbert Powerplant and will be released to the Arkansas River via <br />lake Creek. <br /> <br />F. Twin lakes/Mt. Elbert Forebay <br /> <br />Twin lakes/Mt. Elbert Forebay wi 11 be operated t,o maXlmlze power <br />generation. Twin lakes will, always: 1. maintain sufficient water in <br />storage to be pumped into Mt. Elbert Forebay to allow 1 day of genera- <br />tion or 2. provide sufficient space in: Twin lakes to allow the evac- <br />uation of the 1-day demand from Mt. Elbe~t Forebay. At no time will the <br />water surface elevation in Twin lakes be,less than 9168.7 feet while the <br />powerplant is in service. <br /> <br />. <br /> <br />Flow-through water at Mt. Elbert Forebay will be supplemented by pumping <br />from Twin lakes to allow full utilization of Mt. Elbert Pumped-Storage <br />Powerp 1 ant. Therefore, to reduce purripi ng costs, as much water as <br />possible will be released from Turquoise:lake and diverted from Halfmoon <br />Creek into Mt. Elbert Conduit for use atjthe powerplant. <br /> <br />The minimum release from Twin lakes is 15 cubic feet per second or <br />natural inflow, whichever is less. Table 12 and exhibit 20 show the <br />proposed operation in Twin lakes/Mt. Elbert Forebay Tor water year 1986. <br /> <br />G. Pueblo Reservoir <br /> <br />Water released from storage in Turq~oise lake and Twin lakes during <br />the year, that is not for demands above ~ueblo Reservoir, wi 11 be stored <br />in Pueblo Reservoir. Water in storage (Project, winter water, or water <br />stored under eontract with other ent i ties) wi 11 be re 1 eased on demand of <br />the contractor and administered in the Arkansas River by the Colorado <br />Division of Water Resources Division 2 Engineer. <br /> <br />. <br /> <br />20 <br />
