The main area known as the south fork of the Snake River flows out of Palisades Dam before meeting up with Henry's Fork. The river hosts only wild fish including rainbows, cutthroat, and browns with fish typically ranging from 15-25 inches. It is known for its superb dry fly fishing and considered to be one of the finest in the world. The fishing picks up in early June and goes strong through the summer months. Many anglers enjoy the fall months for the hard fighting fish and the smaller crowds.
