In contrast to the 1950's black and white photo, here is the Dam in 2012, taken during our road trip (eventually) to Alaska.

One of the things to notice is the lens failure on the left side. This became more noticeable over time, and the lens I was using had to be thrown in the "don't use" box.

Also note the low water behind the dam. The water level continues to be a problem.

By the time we took this photo in 2012, there was a highway bridge downstream of the dam. In the 1950's you had to drive over the dam when passing between Arizona and Nevada. Now the road crosses the dam, and stops. You have to turn around. The architecture of the dam itself has been preserved and shows quite an art deco style to it, not visible from here.
