Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. It was referred to as Hoover Dam after President Herbert Hoover in bills passed by Congress during its construction; it was named Boulder Dam by the Roosevelt administration. The Hoover Dam name was restored by Congress in 1947.

Since about 1900, the Black Canyon and nearby Boulder Canyon had been investigated for their potential to support a dam that would control floods, provide irrigation water and produce hydroelectric power. In 1928, Congress authorized the project. The winning bid to build the dam was submitted by a consortium named Six Companies, Inc., which began construction of the dam in early 1931. Such a large concrete structure had never been built before, and some of the techniques were unproven. The torrid summer weather and lack of facilities near the site also presented difficulties. Nevertheless, Six Companies turned the dam over to the federal government on March 1, 1936, more than two years ahead of schedule.

Hoover Dam impounds Lake Mead, the largest reservoir in the United States by volume when full. The dam is located near Boulder City, Nevada, a municipality originally constructed for workers on the construction project, about 30 mi (48 km) southeast of Las Vegas, Nevada. The dam's generators provide power for public and private utilities in Nevada, Arizona, and California. Hoover Dam is a major tourist attraction, with 7 million tourists a year. The heavily traveled U.S. Route 93 (US 93) ran along the dam's crest until October 2010, when the Hoover Dam Bypass opened.

  • Take a short time needed to visit and walk across. Park on the Arizona side for free and take a few minutes to observe this man-made wonder.

  • Hoover Dam was fantastic! The tours were limited due to maintenance and Christmas, so we just drove to the dam and walked up to it. It was incredible to see. I hope to take a tour of the inside...

  • Great detour while in Vegas. The visuals in the area are fabulous. Several areas to view from a handful perspectives. The dam itself is impressive. Even more so when you really dig into the engineering. Super cool experience.
  • A must see! The tour is great! We loved it and the guide was very knowledgeable. We thoroughly enjoyed the whole experience. Even in the dead of summer, it was hot but manageable. We all like the heat though so it doesn't bother us. Not for the claustrophobic.
