TWIN BRIDGES – A full fishing closure is in effect for a portion of the lower Ruby River due to low flows.  The closure extends for about 14 miles, from the confluence with the Beaverhead River to Duncan District Road crossing.

Flows on the Ruby River at a U.S. Geological Survey gauge near Twin Bridges fell below the 5th percentile of daily flow values on May 12, meeting established criteria for the closure.  

The river will remain closed to fishing until daily mean flows exceed 20 cubic feet per second for seven consecutive days, or until Sept. 15, 2021. 

Closures and restrictions of this nature are designed to protect fish that become more susceptible to disease and mortality when conditions such as low flows combine with additional stressors.
