I am Planning a float trip there from Paxson Lake down to Sourdough over the Labor day weekend. I got a caribou permit to fill and I thought what better way to do it than to plan a float hunting/fishing combo trip with two of my sons. I am anticipating the rainbow fishing should be fairly good since the red salmon will more than likely be spread throughout the river with plenty of spawn and carcasses in the river. I have a fairly good selection of beads and flesh fly patterns. I was wondering if anyone on here has done this float in late August/early September, and if so, what tips do you have on flies I should bring for rainbows, lakers and grayling.
