Watch the dam counts. The Wenaha gets a shot of wild fish that will show up in late Sept. and you can pick em' off above the Troy bridge.
November it will get reeeaal good but the pressure will increase.
Some fish will shoot up in the Fall, others will wait it out down below until the Spring runoff and it will be a lure/bait game from then until spawning in April.
Toss in your shotgun because there will be a ton of grouse nearby.
