When a group of South Fork outfitters and concerned citizens approached HFF to expand the science-based collaborative approach to the South Fork, HFF launched the South Fork Initiative (SFI) program. The South Fork Initiative provides HFF the opportunity to influence broad-scale water management for the benefit of the Henry’s Fork and the South Fork, as the two watersheds are highly interconnected. Current projects on the South Fork of the Snake River include: Macroinvertebrate and Water Quality Monitoring, Restoration and Access, and Outreach and Education.
