Fins and Feathers-Bozeman's Tip of the Week

The Gallatin is still fishing well into the fall. dry fly fishing is is less productive than it was. that being said a nice warm sunny day could still produce some decent hopper fishing. But for the most part nymphing will produce the most fishing. Using dark colored rubber legs size 10-14 or a worm down to some good attractor nymphs like perdigons, prince nymphs, and red copper johns. streamer fishing could also be productive with some smaller sized streamers like sparkle minnows and sculpzillas.

The weather is fairly nice for the next few days but we have some colder days with some rain later this week. fishing will go from dry dropper rigs to nymphing and some good streamer days.

Techniques & Tips as of 11/10/22

Dry dropper rigs should be good on nicer days. on the colder days nymphing and streamer will be the best. It's also possible to run into some rising fish on these colder days to BWOs or midges.

Description: About Gallatin River

The Gallatin River is a classic western freestone river. It begins its journey in the northwest corner of Yellowstone National Park, flows through the scenic Gallatin Canyon passing the town of Big Sky, and eventually into the Gallatin Valley where it meets the Madison and Jefferson Rivers to form the Missouri. The Gallatin is characterized by its beautiful surroundings, easy access for wade fishing and abundance of rainbow trout, brown trout, and Yellowstone cutthroat trout. The Gallatin offers year-round fishing opportunities and anglers can be successful with dries, nymphs, or streamers.
