Gallatin River Fishing Report
Current Gallatin River Fly Fishing Report
Updated 08/05/2026
Current Flow: ~ 476 CFS @ Gallatin Gateway
The Gallatin has cleared up really nicely, and for now, everything seems to have settled back into shape. The mud is gone, the river has leveled off, and fishing has been really good again, especially through the canyon. That canyon stretch is probably your best bet right now with cooler water, better clarity, and more consistent fishing.
Spruce moths are showing up in the canyon, and that has created some really fun dry fly opportunities. Hoppers, ants, beetles, caddis, and other terrestrials are also in play, especially in the mornings, evenings, and on windy afternoons. For dries, try Spruce Moths, Royal Chubbies, Tan Chubbies, Yellow Stimulators, Elk Hair Caddis, X-Caddis, Purple Haze, Ant Acids, small foam beetles, Morrish Hoppers, and Water Walkers. If fish are looking up, it’s a great time to cover water with a single dry or a dry-dropper rig.
Dry-dropper fishing has been one of the best ways to fish right now, and nymphing is still working well once the sun gets higher. A tan or royal Chubby with a dropper underneath is a great place to start. For nymphs, Rubberlegs, Girdle Bugs, Perdigons, Rainbow Spanish Bullets, Pheasant Tails, Purple Psycho Princes, Duracells, and Blowtorches, are all good options. If they’re not eating right away, try adding a little weight and focus on deeper pockets, faster runs, and shaded seams.
Streamer fishing has also been worth a look, especially early, late, or under cloud cover. Olive or black Woolly Buggers, Sparkle Minnows, Kreelex, Sculpzillas, Mini Dungeons, and smaller sculpin-style patterns are all good options. The lower river below Cameron Bridge is still under hoot owl restrictions, so don’t fish that stretch after 2 p.m. With temps in the upper 80s and lower 90s coming up, keep checking water temps if you’re down in the valley. For now, the canyon is clear, cool, and fishing well, so get out there and enjoy the Gallatin while it’s in shape.
