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.
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.
Effective 12:01 a.m. May 14, 2020
Per authority delegated by the F&W Commission during their April 26, 2007 meeting, and based on discussions with Fisheries Division staff, a full fishing closure will soon be in effect for portions of the Ruby River from the confluence with the Beaverhead River to Duncan District Road crossing.
Flows on the Ruby River at the USGS gauge 06023000 Ruby River near Twin Bridges MT fell below 5th percentile daily flow values on May 12, meeting fishing closure criteria (ARM 12.5.507).
The river will remain closed to fishing until lifted by FWP administrative action when daily mean flows exceed 20 cfs for 7 consecutive days or until September 15, 2021, at which time the restrictions will no longer remain in effect.
