This is a good place to stop along the drive from Las Vegas to Grand Canyon. It's only about a half-hour from Las Vegas. This engineering marvel is located in Black Canyon, 30 miles west of Las Vegas at the Nevada-Arizona border. It's run by The Bureau of Reclamation, and they started running tours of it in 1937. Its height is 726.4 feet, and it weighs more than 6,600,000 tons. On the other side of the dam is Lake Meade.
Hoover Dam was built from 1931 to 1936 (it took 5 years to complete) to divert the waters of the Colorado River and allow Las Vegas and most of the Southwest to be inhabitable! The dam is named for Herbert Hoover, the 31st president, who strongly supported construction of this dam. The course of the Colorado Rover is 1,400 miles and runs from the Colorado Rocky Mountains to the Gulf of Mexico. The main problems prior to the construction of the dam came from the fact that the river often flooded low-lying areas such as farmland in the spring and early summer as snow from the mountains caps melted. The dam was created to control this flow and ensure a year-round stable water supply. Even today the Hoover Dam provides the hydroelectric power that is used in most parts of Nevada, Arizona, and California.
There is a $10 per person fee to go down to the visitor center and see the "bowels" of the dam and hear the informational talks and see exhibits, and it's well worth it if you make the trip to the dam! One of my favorite parts was seeing the power plant generators: we were able to walk through the 250-foot-long tunnel drilled out of rock and view the 650-foot-long Nevada wing of the power plant and its eight huge generators. There are also murals, maps, photos, and other displays that provide an introduction to Hoover Dam history. Talks by guides are presented every 15 minutes from 9:30am to 4:45pm. Prior to the tour, they take a picture of you in front of a Hoover Dam backdrop, and we thought it would be tacky, but it was actually very cute and we bought it! It also costs $5 to park here, and some people skip the tour of the inside of the dam and simply walk across it to enjoy the views. It's a very informative and historical place to visit!
