VIDEO: Condit Dam Removal in Washington

The Condit Dam held back the White Salmon River in Washington for 98 years. Last week a hole was blasted in the base of the 125-foot high dam, freeing the reservoir behind it.
The lake took less than 2 hours to drain, carrying an incredible amount of sediment and debris downstream to the Columbia. Now, a more gradual process begins–the erosion of millions of cubic yards of trapped silt, the return of threatened salmon and ultimately the complete removal of Condit Dam.
