Washoe Project

The Washoe Project originally planned for facilities in both the Carson and Truckee River basins. The basic plan for the Project was to provide supplemental irrigation water for existing projects, flood control, municipal, and industrial water supplies for Reno and Sparks, fish and wildlife benefits, and recreation. The features of the Washoe Project which have been constructed include: Stampede Dam, Reservoir and Power plant; Prosser Creek Dam and Reservoir; and Marble Bluff Dam and Pyramid Lake Fishway.

Facility:  Stampede Dam and Reservoir - Completed in 1969 this rolled earth and rock-filled structure is 239 feet high and 1,511 feet long. The water storage capacity is 226,500 acre-feet which is reserved by court decree for fishery enhancement, primarily for the spawning of the endangered cui-ui, along the Truckee River downstream from Derby Dam and facilities operation of the Pyramid Lake Fishway. The reservoir also provides flood control, recreation, a reservoir fishery, and other fishery improvements on the main Truckee River, Little Truckee River, and Boca Reservoir.

Prosser Creek Dam and Reservoir Facility:  Prosser Creek Dam and Reservoir - Prosser Creek Reservoir was the initial feature of the Washoe Project. The dam is an earthen structure 163 feet high and 1,830 feet long. It is capable of storing 29,800 acre-feet of water for flood control, recreation, and improvement of fishery flows in the Truckee River. Storage began in January 1963.
Facility: The Marble Bluff Dam and Pyramid Lake Fishway, Washoe Project, was constructed between 1973 and 1975. Marble Bluff Dam is located on the Truckee River approximately 50 miles downstream of Reno, Nevada and approximately 3 miles upstream of Pyramid Lake. It is a zoned earthfill structure with a height of 22 feet and crest length of 1,622 feet, and it has a capacity of 19,700 cubic feet per second through the spillway.
