Dam breached, reservoir drained NOV 04 2011
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.
The time lapse at the end of the reservoir draining is awesome. (★interesting)
