Hoover Dam, Nevada

Monument of the Millennium
Seven Modern Wonders of the World, 1955

Hoover DamThe building of the Hoover Dam provided something positive for the United States to focus on during the years of the Great Depression. Completed in 1935, the 726-foot-high structure was the highest dam in the world, by 300 feet, at the time of construction. It is still the highest concrete dam in the Western Hemisphere. Today, it continues to regulate the flow of the Colorado River and provides a range of benefits, including electricity for more than 1.3 million people and irrigation for 1.5 million acres of land in the United States and Mexico. The Hoover Dam was designated an ASCE Historic Civil Engineering Landmark in 1984 and was named one of America's Seven Modern Civil Engineering Wonders in 1955. The National Park Service designated the Hoover Dam as a National Historic Landmark in 1984.
