Sgt.! FRYINGPAN-ARKANSAS PROJECT, COLORADO 13 " 49. The seven power plants would have a tot.al installed capacity of 104,800 kilowatts and an annual average output of 505 million kilowatt-hours of which 400 million kilowatt-hours would be firm encrgy. Losses would reduce the salahle energy to approximately 467.2 million kilowatt-hours of which 370 million kilowatt-hours would be firm. Associated major pO'l,.Ter facilit,ies include seven switch- yards with It combined capacity of 116,440 kilovolt-ampercs and a transmission system consisting of about 400 miles of I1S-kilovolt lines with nine suhstations. The transmission system would serve customers of the United StMes and would interconnect. with other utilities and enable the interchitllge and wheeling of power from various sources. The Colorado Fuel & Iron Corp. intermittently produces waste-heat electric energy as a result of steel mill operations. If agrecments oould be reached, such energy might be fed into the project system on an exchange basis or under some other arrangement ,,,,.hereby more efficient project power operation would result.. Additional generation in the Elbert power plant might accrue from the exchange of Twin Lakes water involved in the maintenance of fish flows in t.he Roaring Fork River. 50. The Pueblo Reservoir would inundate some 500 acres of irri- gated land. All other lands in the Eastern Slope reservoir sites and for t.he canals are either low-value private lnnd or public land. The eastern slope reser"voil's would require the relocations of about 20 milcs of State highwny and 20 miles of railroad, but no unusually difficult construction problems have become apparent. The high altitude and short working season pose some problems for the Sugar Loaf and Twin Lakes enlargements and associated facilities, The dam and reservoir sites are situated over glacinl moraines \vhich may result in some seepage; however, tightness beyond stability is not necessarv. 51. M"unicipal water syslem.-The project could provide supple- mental municipal water for Colorado Sprinir' and Pueblo. Complete replacemcnt of existing municipal supplies has been rcquestcd by t.he valley to\ms of ~1anz;!1.nola, Rocky Foro, La ~Tunt(}" Lns Animas, La,mar, Crowley, 'Vile)', and Ends. Tentnt,i\'cly, 15,000 acre-feet of project water have bee,n rescrn'd annually for municipal use. Spe- cific municipai supply fnciiities out.linerl hereinafter in paragraphs 52 and 56 fire included in t.hc project plan as tL requested scn'icc. Such construction is propo-;cd only if const.ruction by t.he cOIlllnunities themselves proves to be infeasihle. This phasc of the project is flexible and susceptible of modificntioll or eliminution, in whole or in part, without rendering the remainder of the project economically infeasible. 52, ~upplemental municipal supply for Colorado Sprinirs would iJ1volve~i) exchange of irriglltion watcr by means of project facilities.

En route to the cit.y, the water would generate energy "two municipal power plants, the output of which would exceed '.. loss in the Sk"guay hvckoelectric power plant, on Middle Beaver .Greek, owned by ti,e Solffhcrn Colorado Power Co. Colorado Springs could reimhurse the cc;Inpany for the lost power value. Replacement. of t.he diverted water for irrigation use near Penro~e would be accomplished by divert.ing water from Oil Creek to tbe eXIstIng Brush Ballow Reservoir.
