OK so there is a total collapse those in the know are heading for the hills. There is panic in the streets the government is no more the cops didn't come into work today. How long will Portland exist as a physical place? Cause looking up the river if no one is watching Bonneville, The Dalles, John Day, McNary, Priest Rapids, Dams as well as Grand Coulee Dam and the 8 others upstream And the 15 dams on the Snake and the 9 dams on the Pend Oreille-Clark ForkFlathead and the 8 dams on the Kootenai River All upstream from Portland. For a total of 45 dam on the Columbia River system My guess is the first spring would bring the whole mess down river and nothing will be left of Portland or Vancouver and out to the Ocean. Heck even Oregon City could go if it backs up the Willamette. Just a little food for thought.
