Wild and Scenic River Values Report

The South Fork Snake River, the Teton River, and select tributaries managed by the Bureau of Land Management’s Upper Snake Field
Office represent some of eastern Idaho’s most significant remaining free-flowing river resources. Building upon the BLM’s 2009 Eligibility Report and incorporating updated scientific data, restoration outcomes, economic analysis, and public opinion research, this report concludes that these river segments warrant a determination of suitability for inclusion in the National Wild and Scenic Rivers System.

Together, the nearly 100 miles of river evaluated here possess Outstandingly Remarkable Values (ORVs) that are regionally—and in some cases nationally—significant. These rivers sustain imperiled native Yellowstone cutthroat trout populations, provide essential winter range and migration corridors for mule deer and elk, support exceptional bird diversity, and protect extensive cottonwood gallery forests and rare plant species. They also offer premier recreational opportunities—particularly angling and boating—that contribute meaningfully to the regional economy and define eastern Idaho’s outdoor identity.
