Snake River Area of Critical Environmental Concern, Idaho

The South Fork River (included in this ACEC) is 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.

The U.S. Fish and Wildlife Service identifies this area as the highest-quality cottonwood riparian zone in the western U.S. The entire stretch - but the South Fork in particular - is a high-quality Yellowstone cutthroat trout fishery. Brown, lake and rainbow trout also inhabit these waters.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. Along the banks and on instream islands, bald eagle, elk, moose, mule and whitetail deer, and dozens of bird species find food and living space. Fly fishermen working the Henry's Fork will likely also see trumpeter swans, moose, blue heron and muskrat.
