Mike,
The closet place that comes to mind, is Suttle Lake. It's out Hwy. 34/20, well past Foster/Green Peter. It's about 1.5 hours one way from Corvallis. But, if you're gonna go that far...might as well go another, 10-20 minutes to the Metolius!
WORD: Link Creek, a trib of Suttle Lake, is Closed to all fishing. The lake is open all year. I'd try casting and retrieving any plug, that resembles a small kokanee.
