Actually, yes, but it's all catch and release and no bait, flies and lures only. Upstream from, I think that new Linn County Park Campground past Camp Attitude is called Riverbend? Anyway, go upstream past Riverbend a few miles to where Canyon Creek flows into(you can't miss it there's a bridge Hwy. 20 crosses over called Canyon Creek, which is CLOSED to all fishing) the South Santiam. Start fishing the South just below where Canyon Creek flows in and work your way downstream. Lots of big cutthroat in there, but it's all catch and release. Rainbows too. The Winter Steelhead should have already spawned and moved back downstream or are still in the river up there. Steelhead will die after spawning IF they are too old, swim back downstream or stay in the river for a long time, according to ODFW.
