    Teton River

    river in Idaho

    The Teton River starts in the Teton Mountain Range and flows northwest, offering a mix of gentle meadow sections and more rugged canyon stretches. It's a true freestone river, relying on snowmelt for its flows. Anglers target its abundant cutthroat trout, which readily take dry flies, particularly during the prolific caddis and mayfly hatches. Floating is a popular method to cover water.
