Gallatin River Fishing Report
Current Gallatin River Fly Fishing Report
Updated 06/15/2026
Current Flow: ~ 1170 CFS @ Gallatin Gateway
The Gallatin is dropping pretty quickly right now and is running lower than we’d normally expect for this time of year. Most years we’d still be in pretty heavy runoff mode, but right now the river is shaping up really nicely. It still has that good greenish tint to it, which is honestly a great color for fishing the Gallatin, and it’s definitely looking very fishable.
Think larger rubber legs, girdle bugs, stonefly nymphs, worms, and smaller attractor nymphs underneath. Dry-dropper rigs have been a good way to cover water, and there are some caddis around if you find fish looking up. Streamers can also be worth throwing in the right spots, especially with a little bit of color still in the river.
Overall, the Gallatin is in great shape for fishing right now, so get out there and enjoy it while it’s looking this good. It probably won’t be long until we start seeing salmonflies get going, especially with warmer temps in the forecast next week. Keep an eye out for that report, because once those big bugs start showing up, the Gallatin can get really fun in a hurry.
