About the Colorado River Storage Project (CRSP)
The Colorado River Storage Project is one of the most complex and extensive river resource developments in the world.
The Colorado River Storage Project was authorized by the Colorado River Storage Project Act of April 11, 1956. It consists of four major storage units: Glen Canyon on the Colorado River in Arizona near the Utah border; Flaming Gorge on the Green River in Utah near the Wyoming border; Navajo on the San Juan River in northwestern New Mexico near the Colorado border; and the Wayne N. Aspinall unit (formerly Curecanti) on the Gunnison River in west-central Colorado.
CRSP has a combined storage capacity that exceeds 31.9 million acre-feet. The project provides water-use developments in the Upper Colorado River Basin while maintaining water deliveries to the lower Colorado River as required by the Colorado River Compact. Five federal powerplants are associated with the project: Glen Canyon, Flaming Gorge, Blue Mesa, Morrow Point, and Crystal. Operating capacity of CRSP’s 16 generating units is 1,763,000 kW. CRSP powerplants provide a portion of the electrical needs of more than five million people spread across Colorado, Utah, New Mexico, Arizona, Nebraska, Nevada and Wyoming. More than 2,319 circuit miles of high-voltage transmission lines deliver power to customers.
