<br />3~1.) <br /> <br />FRYINGPAN-ARKAc'lSAS PROJECT, COLORADO <br /> <br />a ] 5-mile supply ennuI would be neeessary. Through fl series of ex- <br />chnnges and ~oonlinl1t,cd operat.ion of the :Mollnt Pi!"gah Reservoir <br />on Oil Creek llIld the Skngllf1Y Reservoir, snt.isfnctofY replacement <br />of irrigation water in the Arkansas Valley could be achieved. <br />5:3. Four thousand ltere-feet of project water nnnually have been <br />allotted to Colom<lo Springs for its immediate requirements. .Of this <br />4,000 acre-fcet., 2,700 nere-feet could be pumped into the city's <br />system from BeaYer Creek. Replacement of this 2,700 acre-feet for <br />irrigation would require 3,200 acre-feet of project water due to <br />t.ra.nsit flnd ot.her losses. The remaining 800 acre-feet of project <br />wate.f represent.s reserve for replacement of possible diversions to the <br />city from other tributaries of the Arkansas River. <br />54. Pueblo requires 3,000 acre-feet of ,Jrojeet water annually. <br />Project facilities would also enable the conservation of 2,000 acre-feet <br />of 'Vurt.z djtch t,ransmollnLain wo.ter for municipal use and treatment <br />of Pueblo's present supply of 21,000 acre-feet. Delivery of water t<> <br />Pueblo would be accomplished from the Pueblo Reservoir through a <br />central svstem for all valley to\VllS. <br />. 55. The valley t<>wns require 8,000 acre-feet of project water <br />annuaUy, of whieh 450 acre-feet. represent.s a reserve for those com- <br />munities and others. The water would entirely replace existing <br />unsati~fflctory supplies. <br />,55, Specific facilities for'suppl}~ng Pueblo and the valley t<>wns <br />wit,h municipal water include a pumping plant at the Pueblo Reservoir, <br />a water treatment plant, a dual pipeline to Pueblo and a small regulat- <br />ing reservoir, a trunk pipeline about 130 miles in length to Lamar, <br />and about 35 miles of branch pipelines t<> Crowley, Wiley, and Eads. <br />. 57. The munieipal water supply system would involve no unusua.l <br />eonstruct.ion problems or difficulties in securing rights-of-way. <br />58. Construction sched1l1e.-About 10 years would be required to <br />construct the initial development. Early concurrent construction <br />of the Aspen, Twin Lakes, and Pueblo Reservoirs, the Fryingpan- <br />Arkansas tunnel, and several cl1stern slopc canals is planned to facili- <br />tate filling the reservoirs. The west.ern slope collection system would <br />he expanded gradually frolll the tmnslllountain tunnel. All hydro- <br />plants except Pueblo have been scheduled for simultaneous comple- <br />tion so their operation can be integrated as a unit. <br />59.
