<br />f}C"' " <br />... .. ~J:J <br /> <br />SUMMARY SHEETS <br /> <br />Narrows Unit, South Platte Division, Colorado <br />Missouri River Basin Project <br /> <br />August 1966 <br /> <br />LOCATION <br /> <br />Northeastern Colorado along the South Platte River. Irrigable lands <br />are in Morgan, Logan, Washington, and Sedgwick Counties. Narrows <br />Dam and. nearly all of the reservoir area are in Morgan County. A small <br />portion of the flood. control pool extends into Weld. County. <br /> <br />PLAN <br /> <br />New construction for the unit will consist only of the potential Narrows <br />Dam and. Reservoir to serve the functions of irrigation, flood control, <br />recreation, fish-wil~life enhancement, and. improvement of water quality. <br />Storage water would. be released. as necessary from the reservoir to <br />supplement irrigation within the service area, totaling 166,370 acres, <br />of the Lower South Platte Water Conservancy District. Supplemental <br />releases will be conveyed downstream in the river channel to the <br />diversion works of existing irrigation systems. No Federal construc- <br />tion of irrigation dictribution facilities would be involved. Specific <br />lands and facilities, including the existing Jackson Lake would be <br />required for recreation and fish and 1aldlife purposes. Minimum do,m- <br />stream flows for water quality control and fish requirements, would be <br />met by reservoir seepage, stream accretions, and. return flows. Future <br />control of Bijou Creek floods could be attained by the construction <br />of diversion facilities and revised reservoir operating criteria. <br /> <br />COSTS <br /> <br />Fcature <br /> <br />Cos ts <br /> <br />Narrows Dam and Reservoir <br />O&M housing. . . . . . . <br />Permanent operating fac:L1i ties. <br />Recreation development .... <br />Fish and wildlife d.eveJ.opment . <br />J'ackson Lake rehabilitation (duaJ. recreatj_on and. <br />fish-wildlife) <br /> <br />$56,300,000 <br />19,000 <br />91,000 <br />2,350,000 <br />2,935,000 <br />125,000 <br /> <br />Total construction cost. . . . . . . . . . . . $61,820,000 <br />
