Gallatin River Fishing Report

Current Conditions

Cold and snowy on the Gallatin River for the next few days but there is light at the end of the tunnel. Late this week and going into next week temps rise into the forties with sun in the forecast as well. Fishing might be tough for the next two or three days but by the weekend Montana’s Gallatin River should be fishing great.

Nymphing will be the most productive means of fishing. Once we get a handful of warm days there could be some Midge hatch activity as well. We are still running a basic fly selection, a red Worm or a small Pat’s Rubber Leg followed by a Zebra Midge or dark small Perdigon should do the trick. Make sure to focus your fishing on the deep slow moving water, inside bends usually create a great hole.

Hazardous obstructions in the river are constantly shifting, making floating here more challenging than other rivers near Bozeman.

Gallatin River Fishing

The Gallatin River starts small in YNP and becomes a medium-sized western river below Big Sky, Montana. It flows through Gallatin Canyon with swift pockets and fast runs. The river is known for its clean, cold water and offers over 75 miles of blue-ribbon trout water accessible at turnouts along HWY 191 and throughout the Gallatin Valley. The Gallatin River joins the Jefferson and Madison Rivers to form the Missouri River near Three Forks, Montana.
