The Teton River is a tributary of the Henrys Fork in southeastern Idaho. It is roughly 80 miles long and flows through the Teton Basin just north of Driggs. The lower section carves through canyons and access is challenging. In 1976, the Teton Dam collapsed destroying the lower part of the Teton River and damaging the stream ecology and the native cutthroat trout population. The Teton fishes well in the summer and can be a great option for anglers who want to avoid the nearby higher profile rivers in the area.
