What Happens Next at Condit Dam?

Pete Springer/OPB

Two weeks ago, the base of the Condit Dam was blown up, and the White Salmon River flowed free for the first time in a century. Scientists watched as the reservoir behind the dam drained in just an hour and a half, the White Salmon River taking huge chunks of the shoreline with it as it charged downstream.

Now scientists will be watching the movement of sediment, as the river carries it from the muddy, empty reservoir down to the Columbia and out to the ocean. As the sediment disperses more evenly, it provides more breeding ground for salmon now returning to the river.

Do you live near the White Salmon River? How does the removal of the Condit Dam affect you? What questions do you have about the restoration process?
