If you go to Yellow Creek put in and float down to the Kellog bridge that is a pretty good float. Other then that you could try putting in at Sawyers Rapids and paddling out in that area, there are probably salmon in there by now (summer steelhead for sure) and there should be bass everywhere you go. The colder weather we had this year didn't really seem to effect the rivers, if anything they are better overall, I would just take senkos, tubes, and rapalas and you should catch fish all day long.
