As readers know, RS loves blowing up old, useless dams. And apparently so does the federal government. Look here at the Condit Dam recently breeched by the U.S. Fish and Wildlife Service to restore salmon waters in Washington State.
In North Carolina there is much gnashing of regulatory teeth and pulling of agency hair regarding the potential for a dam removal to make the water “turbid” (muddy) for some time during removal. As a result, and with some justification, RS dam removals have been managed with very little sediment released. We drain the bathtub slooooowly.
Out West this did not appear to be much of a problem. My educated guess is that the sediment release pictured here at the Condit Dam would be considered “catastrophic” in the Old North State (by the same federal government that pulled the plug on Condit).
Each dam removal has its own special constraints and trade-offs. And I do not begrudge the federal sponsors their ability to break a few eggs when making an omelet of the White Salmon River. But it is amazing how one procedure can be employed in one area — and considered horrific in another.
