Colorado River storage project,

a multipurpose plan, undertaken by the U.S. Bureau of Reclamation in 1956, to control the flow of the upper Colorado and its tributaries and to aid in the development of the rugged, remote upper Colorado River basin; includes parts of Wyo., Utah, Colo., Ariz., and N.Mex. The Colorado River Compact of 1922 established the division between the upper and lower basins and stipulated that the upper basin's water consumption be contingent on the delivery of a set amount of water to the lower basin. Since the flow of the Colorado is erratic, a storage project was needed to maintain an even flow of water to the lower basin in dry years (the estimate of the average flow of the river, however, was based on what historically was a relatively wet period, and was 10% to 25% more than long-term estimates now indicate). A series of dams regulates stream flow, provides storage reservoirs, creates hydroelectric power, and irrigates both new and previously developed acreage. The four major units of the project are Glen Canyon DamGlen Canyon Dam,
710 ft (216 m) high, 1,560 ft (475 m) long, NE Ariz., on the Colorado River. The key unit of the U.S. Bureau of Reclamation's Colorado River storage project, it is one of the world's largest concrete dams (larger in bulk, though not in height, than Hoover Dam).
