Warmer waters mean that several rivers in southwest Montana will close to fishing during the afternoon.
“Hoot-owl” restrictions prohibit fishing during the hottest times of the day — from 2 p.m. to midnight each day. The restrictions apply to the following rivers:
• The lower Gallatin River from the Highway 84 bridge near Four Corners to the Missouri River.
• The lower Ruby River from Duncan District Road to the Beaverhead River.
• The Big Hole River from the North Fork of the Big Hole River to Dickie Bridge west of Wise River, and from Maidenrock fishing access site to the Beaverhead River.
• The lower Beaverhead River from Anderson Lane to the Jefferson River.
• The entire Jefferson River.
Each of these areas have seen water temperatures exceeding 73 degrees for at least three consecutive days.
These restrictions are designed to protect fish such as Arctic grayling and trout, which become more susceptible to disease and mortality when conditions such as high temperatures combine with additional stressors.
The restrictions for each river will be lifted when peak water temperatures stay below 70 degrees for three consecutive days, but no later than Sept. 15.
