Why the South Fork of the Snake River?

Many of us, on our adventures in Henry’s Fork country, have also taken a trip south to explore the South Fork of the Snake River (SFSR). However, during your travels you might not have realized how interconnected flows and management of the Henry’s Fork are to the SFSR. The SFSR from Palisades Dam to the Henry’s Fork confluence is roughly 60 miles long, supports robust populations of Yellowstone Cutthroat Trout, Rainbow Trout, and Brown Trout, and flows through cottonwood stands, canyons, and a braided floodplain. Management of the SFSR system, especially in regards to water management, can directly affect streamflow in the Henry’s Fork.

So, when a group of SFSR outfitters and concerned citizens approached HFF and asked us to expand our brand of research and collaboration to the SFSR, we took note. After serious consideration, HFF has launched the South Fork Initiative (SFI) project. Not only will this new endeavor provide the opportunity to influence broad-scale water management for the benefit of the Henry’s Fork and the SFSR, maintaining a healthy SFSR fishery will help disperse fishing pressure and ensure great fishing opportunities for both rivers. Funding for SFI related projects comes directly from grants and donations designated for the SFI. Donations and funds for the Henry’s Fork are not, and will not, be used for SFI projects. If you’d like to support the SFI by making an additional donation for the SFI, please click here.
