Gallatin River Fishing Report

Posted by: Toby SwankCurrent Conditions
The Gallatin River is still a good choice right now, but the recent cold and snow have slowed things down a bit. Flows haven’t changed much, but cooler nights have backed off some of the bug activity we were seeing earlier in the week.
Fish are holding in the buckets and deeper runs, and that’s still where most of the consistency is coming from. It’s not a day to move fast. Stay on those spots and work through them.
Nymphing has been the best way to get into fish. pat’s rubberlegs paired with a size 16 pink lite brite or a size 16 purple blowtorch has been producing. Keep everything down. If you’re not occasionally ticking bottom, add weight before changing flies.
Streamer fishing has been worth mixing in, especially down in the valley. Darker patterns like olive and black mini dungeons have been moving a few fish, but it hasn’t been as consistent as nymphing.
Dry fly fishing has backed off with the colder weather. BWOs and caddis haven’t been around as much the last couple days. That should pick back up once things warm again.
The Gallatin is still fishing, you just need to slow down and stay focused on the deeper water.
