Should be good to go. I have heard that they are as far up as Challis so any day. I never really fish that far up. I fish the Salmon in the fall, and the Clearwater the rest of the season. However, the upper Salmons a good place to learn with a fly rod. Try the area just below The old Sunbeam dam known as Mormon bend, or further down near Clayton. Good luck.
