The South Fork of the Snake River flows 66 miles across southeastern Idaho, through high mountain valleys, rugged canyons, and broad flood plains to its confluence with the Henry’s Fork near Menan Buttes. Since 1985, the river has been eligible for inclusion in the nation’s Wild and Scenic River System.

The South Fork supports the largest riparian cottonwood gallery forest in the West and is among the most unique and diverse ecosystems in Idaho. It is also home to 126 bird species, including 21 raptors, meriting a “National Important Bird Area” designation. The river also supports the largest native cutthroat fishery outside of Yellowstone National Park. The corridor is also home for an impressive array of other wildlife including moose, deer, elk, mountain goats, mountain lions, black bears, bobcats, coyotes, river otter, beaver, fox, and mink.
