Grand Canyon beaches eroding

FLAGSTAFF, Ariz., Sept. 11 (UPI) -- U.S. researchers said some of the Grand Canyon sandbars and beaches built up by a manmade flood earlier this year are already eroding.

U.S. Geological Survey researchers said photos show erosion is occurring as water releases from Glen

Canyon Dam vary to meet peak power demands and interstate water-sharing agreements, the Arizona Daily Sun reported Wednesday.

Sand in the Colorado River is believed to be linked to the creation of backwaters that could help

promote the survival of some fish species, the newspaper said. Boaters use beaches for camping. Grand

Canyon Superintendent Steve Martin has proposed more regular floods to improve the canyon's ecosystem
