Gallatin River Fishing Report

Posted by: Toby SwankCurrent Conditions
The Gallatin River continues to fish well with steady flows and clear water throughout both the canyon and valley. A mix of clouds and sun is expected through the week, which should keep conditions stable into the weekend.
Nymphing remains the most consistent option. Rubberlegs, wire worms, and squirmy worms are effective lead flies, followed by smaller patterns like perdigons, zebra midges, lightning bugs, or copper johns. Focus on deeper runs and slower seams.
Streamer fishing has been productive in the lower valley sections. Mini dungeons, baby gongas, and sparkle minnows in black, olive, or purple are reliable choices. Retrieve speed can make a difference — slower swings have been best in cooler water.
Blue-winged olives are becoming more active, especially during calm, overcast afternoons. Small emergers or parachutes are good to keep in the box if conditions line up.
Overall, the Gallatin River is in good shape and is fishing well. Nymphing is the most dependable approach, with streamers producing well and light BWO activity beginning to build across the system.
