The Hoover Dam, located on the border of the US states Nevada and Arizona, is one of the most impressive hydroelectric power plants in the world. Built during the Great Depression, the dam provides energy to millions of people and regulates the Colorado River.
1. The Hoover Dam was built in the 1930s
Construction of the dam began in 1931 and was completed in 1936, two years ahead of schedule. The project provided work for thousands of people during the Great Depression, a period of extreme economic crisis in the United States.
2. The dam was originally called the Boulder Dam
The Hoover Dam was initially named the Boulder Dam, after the nearby Boulder Canyon. In 1947, the name was officially changed to honor President Herbert Hoover, who played a significant role in the project’s realization.
3. It is one of the largest dams in the world
With a height of 221 meters (726 feet), a length of 379 meters (1,244 feet), and a thickness of 201 meters (660 feet) at its base, the Hoover Dam was for many years one of the largest concrete structures in the world.
4. The Hoover Dam sustains the enormous Lake Mead
The dam created Lake Mead, the largest artificial lake (reservoir) in the United States by volume when full. This lake is a crucial water source for Las Vegas, Los Angeles, and Phoenix, supplying drinking water to millions.
5. Construction was extremely dangerous
Over 100 workers died during the construction of the Hoover Dam. The extreme heat, explosions, and harsh working conditions made it one of the most dangerous construction projects of its time.
6. Enough concrete was used to build a highway
Approximately 3.3 million cubic meters (4.36 million cubic yards) of concrete were used to build the Hoover Dam. This is enough concrete to build a two-lane highway from New York to San Francisco!
7. The dam generates vast amounts of electricity
The Hoover Dam is a hydroelectric power plant that generates enough electricity annually to power 1.3 million households. The turbines in the dam generate a capacity of 2,080 megawatts.
8. It was the largest power generation project of its time
Upon its completion in 1936, the Hoover Dam was the largest hydroelectric power plant in the world. Although it has since been surpassed by other dams, it remains an important source of renewable energy.
9. The Hoover Dam attracts millions of tourists annually
With impressive views and a rich history, the Hoover Dam attracts nearly 7 million visitors each year. Tourists can take tours inside the dam and cross the nearby Mike O’Callaghan–Pat Tillman Memorial Bridge for panoramic views.
10. Without the dam, Las Vegas would look very different
The Hoover Dam plays a crucial role in the growth and development of Las Vegas. Without the energy and water supply from the dam, the city would never have grown into the entertainment capital it is today.
11. The dam can withstand severe earthquakes
The Hoover Dam was designed to withstand severe earthquakes. Thanks to its massive concrete structure and clever engineering techniques, the dam would remain intact during a major tremor.
12. There is less and less water to hold back
Due to climate change and prolonged drought in the southwestern US, the water level in Lake Mead has dropped dramatically in recent decades. This impacts power generation and water supply in the region.
The Hoover Dam is one of the most impressive engineering achievements of the 20th century. Besides regulating the Colorado River and supplying millions with electricity and water, the dam remains a major tourist attraction and a symbol of human innovation and perseverance.
