<br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />C..qf"' ,~ <br />... ;)($ <br /> <br />Storage in Turquoise Lake was limited to below elevation 9815.8 (46,427 acre- <br />feet) during the fall and early winter months to keep from encroaching on the <br />aggregate pile owned by the Boustead Tunnel contractor. <br /> <br />It was recognized at the time of publication of the 1971 outlook that the operation <br />of Turquoise Lake was effected by the actions of too many different entities to <br />accurately predict an exact operation. An exchange with Pueblo Water Board of <br />Clear Creek water was in progress during the early part of the water year, <br />October and November. These were considered in the outlook and in reality at <br />a rate that would not inundate the contractor's aggregate pile. It was assumed, <br />however, that this pile would no longer be a factor after the end of November. <br />Actually, the aggregate pile interferred with storage for another two months and <br />Homestake imports were curtailed until the end of January. In an effort to off- <br />set the effects of curtailment, Homestake imports were increased above those <br />planned during February, March, and April. <br /> <br />Spring inflow was less than anticipated because the outlook assumed importation <br />of project water from the western slope in May, June, and July. <br /> <br />Work under a painting contract for the metal work in the outlet works of Sugar <br />Loaf Dam causeda reduction in outflow and consequent increase in storage during <br />May. The painting contract covered the period from May 17 through June 6. The <br />increase in storage during the contract period and subsequent release of this <br />water during June 27 through July was accomplished by exchange with Twin Lakes <br />Reservoir water. <br /> <br />By July 2, Turquoise Lake storage had reached its maximum for the year at <br />63,756 acre-feet. Of that amount, 15,925 acre-feet was owned by the CF&I Steel <br />Corporation; 15,710 acre-feet by the Homestake project; 4,763 acre-feet by the <br />High Line Canal Company; 8,109 acre-feet by the Pueblo Water Board; 1,738 <br />acre-feet by the Catlin Canal Company; and 17,511 acre-feet by the Fryingpan- <br />Arkansas project. <br /> <br />In the 1971 outlook it was anticipated that Homestake project imports would not <br />be possible in May and June because of restrictions on use of Lake Fork channel. <br />However, Homestake imported 8, 900 acre-feet of water in May and ,Tune of 1971, <br /> <br />On September 30, 1971, the storage in Turquoise Lake was 56,895 acre-feet. <br />Of that amount, 13,801 acre-feet was owned by CF&I Steel Corporation; 19,276 <br />acre-feet by the Homestake project; 2,115 acre-feet by the High Line Canal Com- <br />pany; 7,397 acre-feet by the Pueblo Water Board; 804 acrc-feet by the Catlin <br />Canal Company; and 13,502 acre-feet by the Fryingpan-Arkansas project. <br /> <br />9 <br /> <br />
