About South Fork of The Snake
The South Fork of the Snake River flows for 66 miles across southeastern Idaho, through high mountain valleys, rugged canyons, and broad flood plains to its confluence with the Henrys Fork of the Snake near the Menan Buttes. It flows northwest from Palisades Dam in Swan Valley. For the first nine miles, the river runs through a narrow channel, then widens and flows around several island complexes. A waterfall can be seen just upstream from the Swan Valley Bridge where Fall Creek cascades into the river. Downstream of Conant launch the river leaves Highway 26 and enters a scenic canyon. The impressive canyon scenery continues downstream until near Heise Hot Springs, where the cliffs give way to a level, but extremely dynamic, flood plain. 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 South Fork is also located near some of the world's best known recreation areas including Yellowstone and Grand Teton National Parks, Island Park, Targhee National Forest, Teton River, Henrys Lake State Park and the Henry's Fork of the Snake River. Among recreationists throughout the country, the South Fork is known as a premier blue ribbon trout fishery, and was selected as the host site for the 1997 World Fly-Fishing Championship.
