I usually fish below Cotter. They have an access point at Cotter below the old bridge. I also follow the train tracks farther down to some spots downstream. Catch some nice Browns and an occasional Cutthroat along with tons of good size Rainbows. As far as flies go cracklebacks, scuds, sow bugs, and zebra midges all work well for me down there. As far as wading goes, it can be dangerous there at times when they generate water fast, but if you're careful you'll be fine. Good luck on the water.
