Gallatin River Fishing Report

Date: 05/01/2026
Posted by: Toby Swank

Current Conditions

The Gallatin River has continued to fish well this week. The river has that green tint and clarity is solid, with fish feeding consistently.

Fish are still holding in the buckets and deeper runs, but there’s more movement during the afternoons as bugs start to show. You’ll find fish sliding into softer edges and transition water when conditions line up, so it’s worth paying attention to where you’re seeing activity.

Nymphing has been the most reliable approach. pat’s rubberlegs paired with a lightning bug, rainbow warrior perdigon, or spanish bullet has been getting eaten. Keep everything down and on pace with the current. If you’re not occasionally ticking bottom, add weight before changing flies.

There are some BWOs and a few caddis starting to show, with the better activity in the warmer parts of the day. It’s not a full dry fly game yet, but there are short windows where fish will look up.

The Gallatin is trending in the right direction. Stay on the deeper water early, watch for bugs in the afternoon, and be ready to adjust when fish start to move.
