If the Spotted Owl didn't trigger any action from the God Squad, then how can removing four dams with the annual output of 950MW and providing just slightly less transportation costs, be considered "great jeopardy"?
Add on the governments own RAND study which states the region would be better off economically if the dams were removed.
This whole issue is nothing more than a house of cards created by the politicians, bureaucrats and special interests.

For those interested in some facts here's the RAND Study and it's conclusions indicating dam removal as the best option for the region.
