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).

After decades of drought, the reservoir created by Glen Canyon Dam has dwindled to just a third full. Now, as the San Juan River flows toward Lake Powell, it rambles over a huge pancake of mud ...
Dams on tributaries are listed if they are taller than 250 ft (76 m), store more than 50,000 acre⋅ft (62,000 dam 3), or are otherwise historically notable. Tributary dams are organized into two lists; those in the Upper Basin, defined as the half of the Colorado River basin above Lee's Ferry , Arizona , and the Lower Basin.
The dam is named for Glen Canyon, a colorful series of gorges, most of which now are buried under the reservoir. Construction of Glen Canyon Dam began in 1956 and was finished in 1966. When the reservoir filled, the dam began to deliver a steady, regulated flow of water downstream and generate a cheap, plentiful supply of electricity.
The U.S. Bureau of Reclamation, which operates the major dams in the Colorado River system, is evaluating issues related to Glen Canyon Dam when Lake Plumbing problem at Glen Canyon Dam brings new ...
Newly discovered damage in Glen Canyon Dam would require releasing less water at low reservoir levels — a problem that increases water risks in the Southwest.
Golden Cathedral. Glen Canyon National Recreation Area (shortened to Glen Canyon NRA or GCNRA) is a national recreation area and conservation unit of the United States National Park Service that encompasses the area around Lake Powell and lower Cataract Canyon in Utah and Arizona, covering 1,254,429 acres (5,076.49 km 2) of mostly rugged high desert terrain.
The dam is responsible for generating hydropower and releasing water stored in Lake Powell downstream to California, Arizona, Nevada and eventually Mexico. The U.S. Bureau of Reclamation, which operates the major dams in the Colorado River system, is evaluating issues related to Glen Canyon Dam when Lake Powell reaches low levels.
