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. Originally known as Boulder Dam from 1933, it was officially renamed Hoover Dam for President Herbert Hoover by a joint resolution of 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 called 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 it is 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; nearly a million people tour the dam each 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.

  • We loved visiting the Hoover Dam. We stopped off while traveling through and spent a few hours there, touring the site and took many photos.  more »
  • Visited with spouse. After security checkpoint, you are allowed to drive on the dam. Plenty of free parking on Arizona side if you can walk a small distance. Great free stop on our trip.  more »
  • It’s good place to visit. Nice open area. East parking. Wasn’t that busy during the week. They said it’s very busy weekends. We were luck to visit easy. Must visit during Vegas trip !
  • Super cool experience! Actually a lot more fun than I thought it would be. The views were breathtaking. The gift shop there isn't too bad either. I got a cute shirt that wasn't too expensive. Not a place I'd thought would be cool, but I really liked it 👍
