Gallatin River Fishing Report

Date: 07/25/2026
Posted by: Toby Swank

Current Conditions

The Gallatin River is finally headed back in the right direction after a rough week. Most of the mud came out of Swan Creek, which pushed the river up and left it off-color for several days. That has started to change, and the canyon is beginning to clear with a green tint that's making the river fishable again.

It's not completely back yet, but every day should be better than the last if the weather stays settled. The upper river through the canyon is in the best shape and will continue to improve before the lower sections.

A dry-dropper is back on the menu. Fish a purple or royal chubby with a beadhead pat's rubberlegs or flashy perdigon underneath. If you're fishing some of the stretches that still have a little extra color, don't waste time changing flies. Add weight first and make sure you're getting down.

There have been a few fish looking up again, but the nymph has still been doing most of the work. As the river continues to clean up over the next several days, expect the dry fly fishing to improve right along with it.

The Gallatin is well on its way back. If you've been waiting for it to recover, this weekend should be the start of some good fishing, and conditions should only get better into next week.
