Lake Mead, from the top of the dam. Although the lake looks low, it is not; the white rim is the high-water mark from a flood in the mid-1980's, when there was exceptionally heavy snow run-off in the Rockies. That flood is the only time that water has ever run over the spillways.

One of the four intake towers; this is the outer tower on the Arizona side. This is one of the more interesting adaptations of art deco and engineering. The towers are several hundred feet tall, and the water intake is 350 feet below the surface. The water depth is about 500 feet to the bottom of the lake, but the towers were built on higher ground.

Looking downstream at the river, outlets, and power station, as seen from the top of the dam. The outlets from the diversion tunnels used to divert the river during construction are near the top.
