Project <br />water stored in the Narrows Reservoir would be released either into the <br />South Platte River through a river outlet for delivery to existing <br />downstream diversion works and through a canal outlet w~rks directly <br />into the Fort Morgan canal. Minimum downstream flows for fishery <br />requirements would be met by stream accretions. return flows. flows f~r <br />Operating the fish hatchery, and minor releases from reservoir storage. <br /> <br />Major recreational facilities would be constructed as a part of <br />the project. It is estimated that approxunately 1,225,000 visitor <br />days could be anticipated at the reservoir area within the first year <br />of operation, with a rapid increase thereafter. <br /> <br />Pro;ect Statistics <br /> <br />Estimated Allocation costs: <br /> <br />Flood Control <br />Irrigation <br />Recreation <br />Fish and Wildlife <br />Highway Improvement <br />Cultural Resource Activities <br />(P.L. 93-291) <br /> <br />$ 20,430,000 <br />92.M4.000 <br />27.328.000 <br />14,581,000 <br />6.380,000 <br />1.490,000 <br /> <br />Total cost (January 1977 Pr1cesl <br /> <br />$162,253,000 <br /> <br />NarrOWS Reservoir capacity (acre-feet): <br /> <br />Dead and inactive <br />Irr igation <br />Joint use <br />(irrigation. flood control <br />and sediment) <br />FlOOd <!ontI:ol <br />SUI:charge <br /> <br />50,000 <br />37:3.000 <br />75,000 <br /> <br />Total capacity <br /> <br />475.000 <br />636.000 <br /> <br />1. 609, 000 a. f. <br /> <br />119. 000 a. f. <br /> <br />2.5 to 1 <br /> <br />Estimated annual irrigation yield <br /> <br />Benefit-cost ratio <br /> <br />Envirenmental Impact <br /> <br />The principal environmental impact of the NarrOWS project will be <br />the inundation of several miles of stream channel by the reservoir.
