Spectacular Time-Lapse Video of Historic Dam Removal

28 November 2011

For 98 years, the 125-foot high Condit Dam in south-eastern Washington State held back the White Salmon River, creating a serene lake, but choking off the waterway to salmon. On the 11th of October 2011, in a historic effort, the dam was dramatically breached, and ecologists hope the increased flow of water will restore the waterway to fish and other aquatic organisms, as well as the birds and mammals that rely on them.

Before the dam was demolished, biologists relocated salmon that were spawning below the structure, so that their reds wouldn’t be covered with silt. The rest of the dam is going to be taken down in the ensuing months.
