Gallatin River Fishing Report

Posted by: Toby SwankCurrent Conditions
The Gallatin River has dropped back into shape with this recent cold snap, and the river is fishing well again. Cooler temperatures slowed runoff down quite a bit, and clarity has improved throughout much of the river.
Fish are back in more normal holding water instead of being pushed tight to the banks. Buckets, deeper runs, and softer seams have all been producing, especially during the warmer parts of the afternoon once water temperatures come up a bit.
Nymphing has been the most consistent approach. pat’s rubberlegs paired with smaller attractors like lightning bugs, rainbow warrior perdigons, spanish bullets, or blowtorches have been getting eaten. Keeping flies down and fishing slower through the deeper water has been the difference.
Streamer fishing has improved with the better clarity. Olive, white, and black patterns fished tight to structure and along the banks have been moving fish, especially on cloud cover.
There have also been a few BWOs and caddis around during the afternoons, although most of the consistency is still below the surface.
The Gallatin is in much better shape than it was during the initial runoff push and is back to being a good option around Bozeman right now.
