On October 26th, a hole was blasted in the base of 125′ tall Condit Dam on the White Salmon River in Washington. In less than 2 hours, the reservoir behind the dam drained completely and the White Salmon flowed unimpeded by a dam for the first time in 100 years.

I was able to watch the explosion live the other day, well live on the internet that is. But the time-lapse at the end of the movie is amazing, showing how draining of the reservoir.
