FWIW, I heard second/thirdhand reports (although they're quite reliable -- big name guides and stuff) that it was quite hot just outside in the ocean Tuesday.
My report would be from Wednesday in the Troutdale area -- even on a 2000 Bonneville fish count day, there wasn't too much in the way of nets coming out of their holders. Heck, a month ago, on days with counts about 800, I was getting takedowns. Yesterday... the final boat count for takedowns was... zero. But at least the weeds were tolerable. Don't see me and my buddy going out in the next few days, since we like to put in a full day, and it was hot Wednesday in an open boat, so I think the next few days are out (and the splash-and-giggle crowd sucks on weekends -- you'd think people who bought a boat that was designed to make as large a wake as possible for wakeboarding would be considerate of people on anchor... and you'd think wrong -- they'll do doughnuts right next to you).
Just about every run has been late the last couple of years (and we all panic), so I don't see why the Columbia Fall Boys should be any different.
