Condit Dam Breach Explained: National Geographic

See never-before-seen video of the dam’s lake draining, and find out how the end result is affecting habitat for salmon spawning. Further dam demolition is scheduled in 2012. The event was a significant milestone for river restoration and dam removal nationwide.
