Gallatin River Fishing Report

Date: 05/11/2026
Posted by: Toby Swank

Current Conditions

The Gallatin River is high and blown out right now. Flows have been rising quickly with the warmer weather, and the river has picked up a lot of color throughout most sections.

Fishing conditions are tough. Most of the river is moving fast, and fish are pushed tight to the banks and into the slowest water they can find. Inside bends, soft edges, and flooded banks are really the only places worth spending time.

For anglers still looking to get out, heavier nymph rigs are going to be the only real option. Worm patterns, rubberlegs, and heavier attractor-style nymphs fished deep along the banks are the best bet. It’s not about covering water right now. Slow down and fish the softer water thoroughly.

Dry fly fishing is off the table with the current conditions, and streamer fishing has been inconsistent with the amount of water moving through the system.

The Gallatin is entering runoff conditions. Unless things cool down significantly, expect flows to keep rising.
