The overflow slipways at the Hoover Dam are massive. This panorama was taken from one of the car parks on the Arizona side of the Hoover Dam and shows one of these tunnels. You could probably drive a car down it. The overflow system has rarely needed to be used, and currently the trend on Lake Mead is for it to be loosing height. The hill behind the spillway is covered in electricity pylons. To the right you can see 3 of the water intake towers that feed the dam's turbines.

Please see the Hoover Dam panorama form more information about the Hoover Dam itself. The dam has become a major tourist attraction, with about 14,000 vehicles crossing it each day, and about 10 million people visiting the dam each year.
The car park from which this image was taken is the only car park on the Arizona side of the dam that charges a parking fee. There is only one car park on the Nevada side of the dam, and that also charges.
