I was talking winter run steelhead Salmo, as that season is upon us. And you're right, most of the fish temps I've taken have been in the morning because I rarely fish all day. It also has a lot to do with fishing methods too. Summer steelhead move to the fly better when the water temps are well up into the 50's for sure. As for chinooks, I don't fish the big warmish Columbia for early fall nooks. In that situation 60 degrees looks real good compared to that recent season's 70 temps. I fish them in spring runoff and after cold coastal rain freshets in fall. I was a likely a little low with my estimates. If I included all seasons and all fishing methods for an average best temp, maybe closer to 50 for steelhead and 53 for chinooks. You're a fish bio so I believe what you say over what I say. What do you other guys that moniter the water temps think?
