Water temps remain very good up and down the river. The mornings are very cool around Big Sky and the fish aren’t moving until the late afternoon. In the valley things are starting up earlier. In the canyon smaller patterns have been better on light 5x flouro leaders (think baetis nympyhs). Down low don’t be afraid to dead drift or strip streamers for larger trout. Baetis on cloudy days are bringing lots of trout to the surface for some entertaining dry fly action.
The Month Ahead:
The Gallatin fishes well in the late fall and early winter. Don’t mess with the fast water as the fish will have moved into the slower and deeper runs by late November. Nymphing smaller patterns and eggs is the big producer.
Long Term Fishing Forecast:
The Gallatin is a great winter fishery, especially near Big Sky where it stays open year round from big ice shelves. It is mostly and afternoon game with smaller nymphs.
