Henrys Fork fishing guide

This Idaho river system offers limited public bank access for anglers seeking Brook Trout. Several named access points—Fall River, Ora Bridge, Vernon Bridge, Chester Wetland, and Fun Farm Bridge—provide entry to the Henrys Fork. Plan ahead, as public fishing opportunities are restricted in most sections.

Current conditions

As of September 1, 2026, Henrys Fork is running around 173 cfs. The nearest streamgage reports flow but not water temperature, so no temp is shown. Conditions look good for fishing right now.
