Gallatin River Fishing Reports
Updated May 24, 24

Flow Data: Gallatin River near Gallatin Gateway, MT

The Gallatin has shaped up nicely. It is green to slightly dirty with nearly 2 feet of visibility. It should remain fishable unless this precipitation pushes a mud plug through. The river is still moving so wading can be tough, but if you find a nice slow moving seam next to the bank you can find fish. Nymphs or streamers have been the best options recently. During these higher flows a big dark stonefly nymph and a worm will produce the best results. In the event that you do find rising fish a #14 attractor pattern such as a Chubby or a Parawulff will likely get the job done. This is the time to use articulated streamers on the Gallatin. While the smaller stuff still works, fish are will to grab something large in nearly any current break you can find. The ebony or Baby Dragon in black are my favorites. When the water clears a bit more with the cold weather this week, an olive or white streamer will gain productivity. Wet and cold today, nice tomorrow, wet again through the weekend.

Montana fishing licenses are available for purchase online at Montana Fish, Wildlife & Parks and at Yellow Dog Flyfishing - Fly Shop (some exceptions may apply). If you are planning to fish in the headwaters of the Gallatin River area above Taylor's Fork (approx. 1 mile upstream); be aware that most of this is in Yellowstone National Park which requires a separate fishing license and is seasonally open to fishing according to YNP regulations.

Fishing from a boat is not allowed on the Gallatin River from the headwaters downstream to the confluence of the West (main-stem) and East Gallatin River, however it is permissible to use a boat/craft for access for wade-fishing in this stretch of the river. Fishing from a boat is allowed downstream of this point to the rivers mouth. Bob's Shuttle provides shuttle service (seasonal) between Manhattan and Three Forks on the Gallatin River and can be reached at 406-595-0587 via voice or text. In general, shuttles should be arrange the day prior or before 9 am the morning of your departure.
