I think there are other factors/alternatives that we should be employing NOW!
How about further restricting the Columbia River salmon "stolen" by other Washington residents who are trollers in Alaska and then get to sell endangered listed fish back here? What about getting rid of Columbia gillnets and transferring the catch to selective fisheries to increase natural spawners? How about reducing the unnatural population of sea birds who devour smolts by the millions? How about eliminating a large portion of the sea lions that devour the adult returning fish? How about reducing the commercial catch of baitfish?

All the above mentioned are easier political solutions than the removal of the dams. Difficult, yes. But do able.
