While there is usually a really good bite right before inclimate weather, Steelhead bite well after a good rain and water levels are dropping back down.
Weekly Report: 09/08/25 - Its going to be a warm week. Probably not the best for bringing in more steel. I have seen some guys catching them from boats in the mouths of the tributaries though. I would expect that any brown trout fisheries would be doing well though if you need to scratch that itch. Just try to fish either early or closer to the evening, which is usually better for brown trout anyhow. Smallmouth are still being caught in good numbers as well so if you go scouting for steel you can pick up some bronze while you're at it. If you're like me you are just doing gear checks, picking up some new leaders and tippet, and tying up some flies. Peak fall fishing will be here before you know it!
