o.J ~. . . "9 (; ,... '.'1 '-,l t... ,. '.f - 2 - The Bureau of Reclamation brought the data on the Fort Morgan dam site up to a basis comparable to the studies made on the Narrows site. These detailed studies indicated that the Narrows Reservoir would inundate only about 1,000 acres more of irrigated land than ~.'ould be in- undated by the Fort Morgan site. The studies indicated that the seepage proglems resulting from the Fort Morgan site would be more critical than those resulting from the Narrows site and that the Ilar"'",."!s would cost .about $2,000,000 less than the Fort Morgan darn and reservoir. The plan n017 proposed by the Bureau of ;reclamation for the Narrovls is the construction of a dam and dil,es across the South Platte and across Bij0u Creek having a total crest ler.gtt of 34,000 ft. and a ma,cLmam height above fOQ,dation of 147 ft. The river outlets and spillYTay would be con- structed on the north side of the river, the river outlets having a capacity of about 4,000 c..f.s. arcd '~he capacity of the spillvla" being about 19,300 c.f.s. A sep&rate out~et canduit TIould be provided for the existing Fort 1l0rgnn .canal. The d3~; """-lId be located about 7-1/2 miles west of Fort I.!organ. The total star&Go capacity of the Narror;s Reser70ir TIould be 1,518,::100 acre-feet, 818,000 acre-feet of which v:o;;.ld be surcharge capacity used to fully capture and control the theoretical spillTIay design flood; 250,000 acre-feet of the ,--emaining 700,0::10 acre-feet ':rould be dedicated to the control of floods and, in addition, 75,000 acre-feet would be llsed jointly for irrigation and flood control; the remaining 375.000 acre-feet would be for regulatory purposes for the purpose of making some flood flows which now cross the state line useable for irrigation, and the making available for use in the s tate of 64,000 acre-feet of Colorado-Big Thompson water which the Bureau of Reclamation estirrates will otherwise annually pass out of the state as unused return flow principally during winter time. It provide is asserted that the Narro1'1s Reservoir project, if built, would the following benefits: 1. Some flood control benefit to the Missouri River Basin. 2. Flood control benefit to the South Platte Basin in Colorado situated below the reservoir. 3. The provision of e!1Clugh "new" ,vater to irrigate 30,000 acres of new lands, a~G th6 prJvision of supplemental water for a substantial irr.i.c" tee, area below the reservoir. 4.
