is PIR under water as well?
I doubt it but I'm going by news coverage and heard of no problems there. I'd check their website if you'd planned on anything. Mt. Hood is adding a 600 inch snow depth to the snow melt so the river will stay high for a bit.
The destruction of Vanport was timely in the sense they knew it was on a floodplain and Vanport existed to build ships for the war.
