The Gallatin River has been fishing the best throughout the early to mid-afternoons. Cold nights have slowed down the mornings, with the river coming to life once things warm up around late morning. The canyon and valley are both worth fishing, but clear water means anglers should be a little more careful getting into position.
Keep a few purple hazes and parachute adams around for the afternoon. There have been stretches where a smaller dry is all that’s needed.
The lower river is also worth covering with a streamer. Baby gongas and smaller sculpin patterns in olive or black have been moving some better fish as the water cools.
