Visitors enjoy a multitude of recreational opportunities on the river such as rafting, fishing, and photography. The river is 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 trout (Oncorhynchus clarkii behnkei). The 2009 Snake River Headwaters Legacy Act designated the river above Jackson Lake as a Wild and Scenic River. The Lewis River is a tributary of the Snake River. The Snake River—a major tributary of the Columbia River—originates in Yellowstone National Park, and then turns south, passing through the John D. Rockefeller, Jr., Memorial Parkway into Grand Teton National Park. The river flows through Idaho and joins the Columbia River in Washington. The Snake River is 1,040 miles long (1,674 km); 42 miles (68 km) of it are in Yellowstone National Park. The river feeds Jackson Lake—a natural lake augmented by a dam, resulting in regulated downstream flows since 1907.
