Snake River

The Snake River originates in the Teton Wilderness, flows north into Yellowstone National Park, and then turns south, passing through the John D. Rockefeller, Jr., Parkway into Grand Teton National Park. The river feeds Jackson Lake—a natural lake augmented by a dam, resulting in regulated downstream flows since 1907. Visitors enjoy a multitude of recreational opportunities on the river such as rafting, fishing and photography. The river is also home to a wide variety of riparian and aquatic species, including the native Yellowstone cutthroat trout and an endemic variety, the Snake River fine-spotted cutthroat. The 2009 Craig Thomas Snake River Headwaters Act designated the river above Jackson Lake as a Wild River. The Act further designated the river from a mile below Jackson Lake Dam to a mile below Moose, WY, as well the tributaries Pacific Creek and the Buffalo Fork as Scenic Rivers, indicating the high value these waters provide the nation.
