You Know?
Glen Canyon Dam, a concrete structure rising 710 feet above
the Colorado River, was completed in 1963. The dam provides
essential water storage and power for much of the southwestern
United States.
Lake Powell was formed by Glen Canyon Dam and named in honor
of Civil War veteran and one-armed explorer John Wesley Powell,
who led a scientific expedition in wooden boats down the Colorado
River through the Grand Canyon in 1869.
Lake Powell took 17 years to fill, reaching "full pool"
in 1980. The lake has a storage capacity of 27,000,000 acre-feet,
making it the second largest man-made reservoirs in the country.
