Nathan,
Any time the Sky drops below 7000fps at Sultan it will be fishable at Reiter. Saturday it dropped from 7000 to 5000fps and it was good both sides. Still runnin' at 13,400fps as of 8:30pm tonight, but it will drop fast if there is a break in the rain or it gets colder up there, and snows.
I'm pretty sure this won't be anybody's zipper lip, so I will share this info with you, there is a good bit of river bank almost neglected at Reiter, down river on the south side, up on both sides, don't be afraid to get away from the crowd, you might be pleasantly suprised.
Good fishin'
cool
