Remote operation of reservoir outlet structure to respond to any detection of <br />imminent dam failure and provide year-around operation capability. <br /> <br />. Correction of erosion problems currently associated with Puppy Dog Lake <br />drainage. <br /> <br />. Ability to store additional water and meet long-term future water demands for the <br />City and Mt. Werner. <br /> <br />. Augmentation of in-stream flows below the intake to the water filtration plant; <br />Fish Creek would remain a live, year-round stream to the confluence with the <br />Yampa River. <br /> <br />. Increase in high mountain lake aquatic habitat and reduction of stream habitat for <br />fish at the reservoir site. <br /> <br />. Maintenance of a 1,030 AF fisheries pool in the reservoir. <br /> <br />. Minor depletion of water for downstream endangered fish species habitat. <br /> <br />. Relocation and upgrading of Granite Campground with improved accessibility for <br />the physically disabled. <br /> <br />. Upgrading of service roads. <br /> <br />. Temporary impacts to road conditions and transponation safety along Buffalo Pass <br />Road and site access roads during construction. <br /> <br />. Temporary displacement of Fish Creek Reservoir visitors and other recreationim <br />in the area during construction; Granite Campground would be unavailable until <br />relocated and rebuilt. <br /> <br />. Temporary impacts to fishery during construction; reservoir would be drained and <br />no fishery would be sustained during the proposed two-year construction period. <br /> <br />. Debt obligation for the City and Mt. Werner for the $6,000,000 expansion; cost <br />would be shared between the City (25%) and Mt. Werner (75%). <br /> <br />A further examination of impaas is presented in Section 2.5, Comparison of Alternatives Analyzed <br />in Detail and in Chapter f, Environmental Consequences. <br /> <br />ALTERNATIVE C - SMALLER RESERVOIR EXPANSION <br /> <br />Under Alternative C, the Forest Service would issue a new Special Use Permit to the City to <br />enlarge, use, maintain and operate the Fish Creek Reservoir. The expansion would provide for an <br />additional 908 AF of water storage capacity. The size of the reservoir would be increased to 112 <br />surface acres, a change of about 22 acres from its present size. The main dam would be raised eight <br />(8) feet and the saddle dam would be raised 10 feet. A spillway channel would be constructed, <br />adjacent to the saddle dam. An early warning and remote operational control system would be <br />installed. The City and Mt. Werner would share in the financing of this smaller reservoir expansion. <br /> <br />:::":'?~~::::ii:::;:m:':.'::'::::;;::>>.$;:;.;:::;..;::::..::;;~:;;;:::~:::;,:;;:.;<:,:t3m.:;:::::;:;:3,::':::<:;::.:;;,:<<:::;t";x.;.,:.::::;>>::>::.:%~:>>::::;:;:.;:1<{.~:.;;;;;:.;~:&:;~r::f;.;:;;:';,:::;::S~of.:t.:t:<<::),-::-;.::;;;:;:;:;:;:::::;::K'l=:;.::::~:-:::::,,;,<'::'::'::::~:::*:;:;.::3~,':;:::i,:;;;;:::::..~:::.~:;:.x;";;:';;:::::.;>>~:;3i$;: <br /> <br />Page S.8 <br /> <br />September /993 <br />
