. 0852 SU;'IT"JARY SREETS Bluestone project LOCA~'IOH: iJear the Colorado River and its tributary, Roan Creek, in the vicinity of the towns of Rifle and DeBeque in Garfield and (.lesa Counties of "est-centr~l Colorado. PLAN The project would utilize water fro~ the Ruedi Reservoir on the Fryingpan River, a feature of the authorized Fryingp~n-Arkansas project, and from Roan Creek for the irrigation of 8,176 acres of land, including 6,304 acres of full service land and 1,874 acres of supplemental service land. Natural flows of the Colorado River would be used for power generation. Project effects in other fields have not been evaluated. . 11ater for the SharrRrd Park area, consistin" of water released from Ruedi Reservoir, would be pumped from the Colorado River at a point about 6 miles d~<nstream fro~ Rifle, Colo. Three pumps in series would deliver water to successively higher sections of the Sharrard Park Pump Canal or its laterals from which the water would be dis- tributed to the land. R~servoir water for irrigation in the Roan Creek area and n2tural flows for power production would be diverted from the Colorado _ River at the Una Diversion De~ located about 4 miles downstream from Grand'Valley, Colo~-'rEe' Una !'ower canarvouhth,,~,l ~.L Lhe-------- dam and extend south 4.4 miles to the Una Powerplant. The river water would be released throul"h the po';erplant and '..rould return to the river. The reservoir water would flow from the terminus of the Una P~ler Canal to the Una Pump Canal. A lift of about 1,25 feet would be provided about 3.8 miles alonl" the course of the pump canal by the Una Pumping Plant. Farther alon~ the canal and near its terminus on Roan Creek the !.:t. Logan Reservoir would be COn- structed. Water would be pum~ed for irri~ation and for storape during hours of off-peak power de~p.nd. Irrif.ation needs during daily perioisof peak power demands would be met by releases from Mt. Logan Reservoir. Irrifetion water delivered to Roan Creek would be used on lower lands served from the creek and in exchanRe part of the Roan Creek water now used on the lower lands would be used on higher lands along the creek and its tributaries. . The Sharrard Park and Una Pumpin~ Plants would utilize part of the power venerated at the Una Pow~rplant. The remainiDf power would be delivered to transmission lines of the Colorado River Storafe project near Rifle for commercial sale. 5
