Hoover Dam stretches from the Nevada shore of Lake Mead to the Arizona shore, trapping the waters of the Colorado River to provide energy to much of the surrounding area. When finished in 1936, it was the largest dam in the world, but that claim was passed to the Grand Coulee Dam, when it was opened in Washington. Hoover Dam now ranks 38th in hydroelectric energy in the world.
As of this writing, the Hoover Dam is still open to vehicular traffic, but a new bridge is underway within a few feet of the dam. Once opened, the dam will be open to tourist foot traffic only.
There are two tours that take you inside the dam. We took the shorter, lasting about 45 minutes. For pictures of the dam, lake and from the tour, click on the map.
