Gallatin River Fishing Report

Posted by: Toby SwankCurrent Conditions
The Gallatin River is fishing well and continues to be one of the better options around Bozeman. The canyon has been the most consistent stretch, with plenty of fish looking up throughout the day. The lower river remains under hoot owl restrictions from Cameron Bridge to the Missouri River, so anglers fishing below the canyon need to be off the water by 2 p.m.
Dry fly fishing has been good. Chubby chernobyls, stimulators, and spruce moths are all producing fish, with the evening caddis hatch providing some of the best surface action of the day. If fish stop eating on top, a small olive or black perdigon below the dry has been enough to keep the action going.
The Gallatin is in great shape for August. If walk-and-wade fishing is the goal, it's hard to beat right now.
