Lake Powell is a water storage facility for the Upper Basin states of the Colorado River Compact ( Colorado, Utah, Wyoming and New Mexico ). The Compact specifies that the Upper Basin states are to provide a minimum annual flow of 7,500,000 acre-feet (9.3 km 3) to the Lower Basin states (Arizona, Nevada, and California).
Glen Canyon Dam is a concrete arch-gravity dam in the southwestern United States, located on the Colorado River in northern Arizona, near the city of Page.The 710-foot-high (220 m) dam was built by the Bureau of Reclamation (USBR) from 1956 to 1966 and forms Lake Powell, one of the largest man-made reservoirs in the U.S. with a capacity of more than 25 million acre-feet (31 km 3).
Lake Powell, impounded by Glen Canyon Dam, is the second-largest reservoir in the U.S.. This is a list of largest reservoirs in the United States, including all artificial lakes with a capacity greater than or equal to 1,000,000 acre-feet (1.2 km 3).
The 'central bank for Western water' Lake Powell is one reservoir in a complex water system along the Colorado River, which supplies water to 40 million people and provides irrigation for 5.5 ...
Federal officials are confident water levels will rise in the coming months once snow melts in the Rockies. Lake Powell's fall to below 3,525 feet (1,075 meters) puts it at its lowest level since ...
Lake Mead can store more than 27 million acre-feet of water, and Lake Powell 25 million acre-feet. By contrast, Shasta Lake can hold about 4.6 million acre-feet, and Lake Oroville 3.5 million acre ...
Glen Canyon Dam, a concrete arch dam on the Colorado River in the American state of Arizona, is viewed as carrying a large amount of risk, most notably due to siltation. [citation needed] The Colorado and San Juan rivers deposit large volumes of silt into Lake Powell, slowly decreasing its capacity. The sediment will eventually build up against ...
If Lake Powell recedes much further, one of the nation’s largest reservoirs could be at risk of no longer generating hydropower for the region. The lake was just under 24 percent full as of last ...
