Dam is located 30 miles southeast of Las Vegas in Black Canyon. The dam's
purpose is to help control the rushing Colorado
River and create a large water reservoir.
Construction began on the dam in 1931 at a cost
of $48.8 million. It was originally named Boulder Dam, but the name was
changed to honor President Herbert Hoover. Standing more than 726 feet
high, and weighing more than 6.6 million tons, Hoover Dam is an engineering
History of the dam
During the 1930s, the United States was suffering from the Great Depression.
Across the nation, many people were out of work and were forced to seek
employment in other parts of the country. The construction of Hoover Dam
created jobs and brought people to Southern Nevada.
Dam was completed March 23, 1935. The dam caused Colorado River water
to pool behind it, creating Lake Mead. The lake serves as a giant water
reservoir, and we get 88 percent of our water supply from the lake.
Serving the Southwest:
- The dam is important for flood control. The dam helps hold back water
during wet years to prevent flooding.
- Farmers receive a dependable water supply to irrigate crops.
- The Colorado River carried tons of sediment which damaged canals and
irrigation ditches, costing millions of dollars to repair. Hoover Dam
traps the sediment allowing the water to flow smoothly.
- The dam produces pollution-free, low cost hydroelectric power for
the southwest. The dependable water supply and the low-cost electricity
helped areas of Southern Nevada to grow and flourish.
