As for the dams I disagree. The dams will come down. Probably not in my lifetime, but they will not last forever. Many many dams are coming down in the midwest and east coasts because their dams have become so old they have to be removed for safety.

Age grand coulee a couple of hundred years and/or add a 8.0+ earthquakes and it too will be gone.

Human daming of the columbia is nowhere near the worst catastrophe salmon have endured over geologic time on the columbia river. There have been cataclysmic floods, ice dams, volcanic eruptions, glacial intrusions, etc.
They will come back as soon as there is habitat to support them. It would be nice if we could help speed up the process. Unfortunately an energy alternative will be necessary to remove the big power generating dams (ie grand coulee).

The snake dams don't make any sense on the national level. We subsidize farming via lirrigation dams in the deserts of washington and idaho while we pay farmers in the midwest not to farm where no irrigation is needed at all. Why not tear down the snake dams, make up for the lost acreage by bringing the fallow acres in the midwest back online and save a ton of federal $. Oh, and we get to help endangered salmon. What's not to like about this plan?

Aunty, I am not terribly familiar with the habits of the CR gillnetters, but I won't defend them. I don't doubt they are greedy. This is the nature of extractive industries, especially those that extract public resources. Always looking for the quick $.
