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.
ATLANTA (AP) — Plumbing problems at the dam holding back the second-largest reservoir in the U.S. are spurring concerns about future water delivery issues to Southwestern states supplied by the Colorado River. Federal officials recently reported damage to four tubes known as “river outlet works” at Glen Canyon Dam on the Utah-Arizona border.
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.
And 35 feet below that threshold, the Glen Canyon Dam, which created Lake Powell, is at increased risk of damage and being unable to produce electricity for the 5 million people it serves.
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).
