Welcome to OR and to the Forum! As far as salmon near corvallis-they cruise right up the willamette here but you don't hear about too many guys catching them-not good holding water I suppose. Aside from the Willamette, there's the N and S Santiam, Alsea and Siletz which are all within an hours drive from Corvallis.
You're gonna spend mucho dinero on gas tryin to get to all the different systems that hold fish that are around you. You're pretty much within an hour's drive from some great fishing.....no matter what direction you go.
Thank you very much guys!!! I will not be down there til the first week of July. When I get there, I look foward to hookin up with whoever wants to go. I'm always willing to share info and knowledge as well as receive it. I look foward to fishin with yall soon.
