Conditions

Steelhead numbers are thin on this reach in October, and angling pressure is light. As of October 18, flows were stable around 13,400 cfs near Anatone. With cooler water, sink-tips and weighted flies become essential. Traditional patterns may take a few fish early, but you'll shift to dredging as conditions settle into fall rhythm.
