The Gallatin is a solid producer right now. The best fishing is up in the canyon. In the valley a very early start is advised. Spruce moths are on the water early in the morning in the canyon before the sun hits the water. Fishing slows down after lunch and then picks up again in the hour before dark. The lower river has less water due to irrigation and fishing in the middle and lower valley is closed after 2pm to protect fish from warmer afternoon water temperatures.
The Month Ahead:
The Gallatin will continue to fish well during the low light hours. As flows continue to drop and the river warms the peak fishing window will slowly move to earlier in the day and morning fishing will out produce afternoons.
Long Term Fishing Forecast:
The Gallatin will be a good option in late summer and fall. In the fall the valley fishing improves as temperature drops. Baetis hatches in late September and October can produce some dry fly action.
