Gallatin River Fishing Report

Posted by: Toby SwankCurrent Conditions
The Gallatin River is a good choice right now. Conditions have stayed pretty similar the last few days, and the river still has that green tint through the canyon and into the valley.
Fish are holding in the buckets and deeper runs, they’re not moving a ton with the cooler nights, so it pays to slow down and work those spots instead of covering too much water.
Nymphing has been the best way to get into fish. pat’s rubberlegs paired with a size 16 pink lite brite or a purple blowtorch has been producing. Keep everything down and don’t rush your drifts. If you’re not occasionally ticking bottom, add weight before changing flies.
Streamer fishing has been worth mixing in, especially down in the valley stretches. Darker patterns like olive and black mini dungeons will move a few fish, but it’s still not as consistent as nymphing.
Dry fly activity has been limited with the colder nights. BWOs and caddis haven’t been showing like they were earlier, but that should pick back up once things warm again.
The Gallatin is still fishing, you just need to stay patient and keep your flies where the fish are.
