eGil... -, ,. ,IfI~. . ""!'R..-..:t, Fryingpan-ArkansllS Project Ruedi Dam and Reservoir The North and Sonth Side Collection Systems on the western slope are being built to collect the melting snows and runoff from the high mountains. The diverted waters of the Fryingpan and Roaring Fork River Basins flow into the inlet portal of the Charles H. Boustead Tunnel. This tunnel conveys all the water from the North and South Collection Systems through the Continental Divide to Turquoise Lake. The Eastern Slope Turquoise Lake and Sugar Loaf Dam are located just east of the Continental Divide, approximately 5 miles west of Leadville, Colo. The lake provides storage capacity for the regulation of project water flowing from the Charles H. Boustead Tunnel. Mt. Elbert Conduit, a 1O.7-mile-Iong, 90-inch-diameter pipe, will convey water from Turquoise Lake to Mt. Elbert Forebay. The Halfmoon Diversion Dam will in- tercept the excess flows of Halfmoon Creek for diversion to Mt. Elbert Conduit. Water delivered to the forebay will be used for generation of power in the Mt. Elbert Pumped-Storage Powerplant. The powerplant is at the northwest corner of the lower lake of Twin Lakes. After going through the powerplant, the water will flow into Twin Lakes. The plan provides for a new dam approximately 2,500 feet downstream from the present Twin Lakes. From Twin Lakes, the water will be conveyed through the Otero Canal to the Otero Powerplant at Clear Creek Reservoir. Power generated at the Mt. Elbert Pumped- Storage Powerplant and the Otero Powerplant will be delivered to existing power transmission systems in the area. From Clear Creek Reservoir, the water will flow down the Arkansas River to Pueblo Dam where some of the 3 project water will be diverted to the Fountain Valley and Arkansas Valley Conduits for delivery to municipal and industrial water users. The Pueblo Reservoir is the ter- minal storage feature for the project. The Arkansas Valley Conduit transports water for municipal and industrial uses from Pueblo Reservoir to towns in the Arkansas Valley as far east as Lamar, Colo. When completed, the project will provide an average annual diversion of 69,200 acre-feet of water from the western slope to the eastern slope. Ruedi Dam and Reservoir Ruedi Dam is on the Fryingpan River about 15 miles east of Basalt, Colo. The dam creates a reservoir with a total capacity of 102,369 acre-feet. Ruedi Dam is a rock and earthfill structure that stands about 285 feet high above streambed, has a crest length of 1,042 feet, and contains approximately 3,745,200 cubic yards of material. The concrete spillway structure has an uncontrolled ogee- type crest, a chute section, a stilling basin, and a bridge over the spillway. The spillway has a capacity of 5,540 cubic feet per second. The outlet works, located under the right abutment of the dam, consists of a hexagonal intake structure with trashracks and a bulkhead gate, a IO-foot-diameter concrete-lined circular tunnel to a gate chamber housing a 5- by 6-foot high-pressure gate, an II-foot-diameter concrete-lined horseshoe tunnel to a gate chamber housing a 5- by 6-foot high-pressure gate, an II-foot-diameter concrete-lined horseshoe tunnel with a 76-inch-diameter steel pipe, a control house with two sets of 3.5- by 4-foot tandem gates and wye to a 76-inch- diameter steel pipe stub with a bulkhead just ahead of the control house. This bulkhead is to provide service to a future pipeline which will supply water to the potential Basalt Project. A shaft house and adit give access to the gate chamber of the outlet works and auxiliary works. The capacity of the outlet works is 1,810 cubic feet per second. The auxiliary outlet works consists of an intake structure with trashracks, a 6-foot-diameter concrete-lined circular tunnel to a gate chamber housing a set of 2.5- by 3-foot tandem gates, and a concrete-lined 5- by 6-foot flat- bottom tunnel. The capacity is 600 cubic feet per second. A concrete bypass, consisting of a concrete chute and stilling basin, bypasses flows of Rocky Fork Creek past the discharge of the spillway and auxiliary outlet. Sugar Loaf Dam and Turquoise Lake Sugar Loaf Dam and Turquoise Lake are east of the Continental Divide on the Lake Fork of the Arkansas River in Lake County, approximately 5 miles west of
