No fish will be saved by this. Quite the opposite. It will also kill birds, small mammals, and people.
And, once they've gotten the Snake dams, they'll start coming after the Columbia ones.
At no time will they discuss the way the Columbia is essentially blocked by nets at The Dalles, or the countless barriers, diversions, and culverts that block the small tributary streams (where salmon actually want to spawn) throughout western WA and OR, or the billions of gallons of water pulled from the Snake so that alfalfa and potatoes can grow in the southern Idaho desert. They'll also forget about international commercial fishing in the north Atlantic, the decline of salmon even in the rivers without dams, and the fact that the salmon population in the Columbia watershed was decimated by commercial canning to the point that many of the canneries were no longer economically viable...a full two decades before the first major dam on the river was built.
None of that matters, because Jay wants a car that doesn't make noise, and he wants windmills on every ridgeline in Eastern Washington. Doesn't matter that those windmills are so inefficient and economically questionable that nobody would even build them if there weren't government subsidies. Doesn't matter that tremendous amounts of carbon go into producing every one of them...and into transporting them...and into erecting them. Also doesn't matter that they never reach their rated capacity, because the wind doesn't blow the right speed all the time...and doesn't blow when the power is needed. And, most of the electrical utilities won't point any of this out, because with the dams gone they'll be able to raise rates...and if they're relying on unreliable power from windmills, they can probably raise them even more. Except when there are brownouts...and there will be.
Not that I have a position on this issue.
