Having lived in the area, and being both a fish hugger and economic conservative, all I can say is that demolition will start local shootouts. To say that emotions run high is an understatement. This is all or nothing to most locals.
These C-suckers have no idea how many potato farmers are there south of K Falls OR.
All of them rely on the water from that system to irrigate.
Rice farmers also.
Would take just one incident and the farmers there could put the entire west coast into a blackout for a long time.
I lived in Kfalls from 2000-2002 when they shut the water to the farmers/ranchers in the basin. The emotions were certainly high at that time.
