Sun River
Emergency river closure due to bridge construction (closed to all forms of use) are in effect for the Sun River - beginning 500 feet upstream and ending 500 feet downstream of the Sun River Bridge (also know as Pishkun Road Bridge) starting July 30.
Adoption of an emergency rule closing a portion of the Sun River (MAR Notice No. 2025-301.1).

North Fork Blackfoot River
A Drought Closure (fishing prohibited 24 hours) is in effect for the North Fork Blackfoot River from USFS boundary downstream to Highway 200 starting September 10.
Streamflows were measured at the DNRC Ryan Bridge Gage 76F 03500 and have remained below critical threshold of 5 cfs since September 1st.
Beaver dams and braided channel morphology have combined with extremely low flows in the hydrologic-losing reach to create conditions that are expected to concentrate adult bull trout as they attempt downstream migrations to the Blackfoot River.
The closure criteria follows the Blackfoot Drought Response Plan.
