C'-J ~ ~ c::. In beth ?lans a conve~cio~l po~erpl~nt w~uld be si Lu3ted at the bdse of thE" rl.1m. Those plnncs would have a max1~um ~apacity of 18 and 36 megn- .....atts respectively 3nd .~cI11d product! about 136,000,000 a~d 159.000,000 kUh ot energy annually respectively. The pumpback peak-demand powerplant ~nd reservoir (Rim Basin Reservoir) would be con- structed about 800 feet above Dominguez Reservoir and <!bollt 9 miles up$trea~J from Dominguez Dam. These facilities ~~uld ha~e a capacity of 500 megawatts. Rim 83sin Reservoir would be created Ri~ Basin Dam around a natural basin canyon riQ above the Cunnison River. ,"auld be a horseshoe-shaped structure emhankment of zoned earthfill. by building on the east The dam with an A J:lultile....el outlet ,,'orks would be built at Domin- guez D~m (either size) to permit control of do~~- streae water temperature. thus ~~intaining n~tive fish habitat. Some riparian lands ~ould be ac- quired and developed upstream from Dominguez Rese~vQir co Roubideau Creek and downstream from th~ dam to the Rcdlands Power Canal Diversion Dam. Ie either plan. b3ck~ater areas and nesting structu'l"CS would be developed for fish and wild- lif~. and wildlife zoning would be establish~d a- round portions of the reservoir for the protec- ti~n of c~rt3in s?ccies such as the bald eagle. Municip,:l! .Jnd industrial water from the project (ultimat~ capacity 74 cfs) would help meet the D('lr.tin~II~Z Rl>.o;~rv"": r :'r.' !"."C Jalluary-. iSd-2~- ragl" ~ llC :! needs of anticipated popul.'ltion inc'rea~es in the Grand Valley orea and would bl? prClvicl.:-c in eiC:'81' pIon. Attractive recreational and f'ishin; cpportllnities are expected since the 1'03xilJum T(>scr....oir fluctu'.!- tion would be limitEd to about 20 feet in the ?eaking Power Plan and 61 feet in the X&I Plan. Recreacional facilities would b~ provided at several sites on Dominguez Reservoir, while picnic and rafting facilities would be devel- oped on the river dowllstrea~. A visitor center/ museum would be constructed to explain chc ~roj- ect and iaterprec and display cultural resources of the area. Construction of the project would necessit3te re- location of the Denver and Rio Grande W~stern ~il- road to a new alignment roughly par~llel to U.S. Highway 50 between Whitewater and Delta in both plans. In addition a small portion of U.S. High- way 50 would be relocated araund the Kannah Cre~k arm of the larger Dominguez ReservQir. Transmisstion lines would be ~onstructed from Dominguez Dam Pumping/Po~crplant to th~ switch- yard and from Rim Basin Pumping/Cenerating Flant to the switchyard in the pe3kin; pow~r plen. Existing transmission sys:ecs ~~uld be us~d to transmit the po.er to Co3vrado Rivet Storage Project delivery points. The Department of Enerey W~stern Area Pow~r Aaministr~tion wou:d be responsible for tr~n~mis~lon and marketing of pO'der.
