The Hoover Dam is located on the Colorado River about 50km (30 miles) southeast of Las Vegas Nevada. When it was completed in 1935 it became the largest hydroelectric station in the world. Until then the Shannon Hydroelectric Scheme in Ireland was the largest. The Hoover dam was called the Boulder Dam at first. The name was changed to the Hoover Dam in 1947.
Construction on the Hoover Dam began on September 17th 1930. It was completed more than two years ahead of schedule. Both the Shannon Hydroelectric Scheme and the Hoover dam continue to supply electricity in their respective countries. The Shannon Hydroelectric Scheme supplies 2% of Ireland’s power. The Hoover Dam supplies electricity to California, Nevada and Arizona.
The Hoover Dam generators began to generate electricity from the Colorado River and transmit it 266 miles to Los Angeles for the first time in the year 1936 On This Day.
