Gallatin River Fishing Report

Posted by: Toby SwankCurrent Conditions
This weekend is pretty cold on Montana’s Gallatin River with temps in the high twenties and snow in the forecast. Next week is looking much warmer with some days reaching the fifties. If you are thinking about braving the cold this weekend there is definitely still some fishing to be had. Nymphing will be the way to go but we could see a sporadic Midge hatch as well.
Anglers have been doing well fishing a Red Worm or a Pat’s Rubber Leg as the lead fly. Below that we are fishing Zebra Midges, small Perdigons, and Micro Mays. Anglers are still finding most of their nymph fish in the slow deep holes. Make sure to add some split shot about a foot above the lead fly to get those flies down fast.

Gallatin River Fishing Trips
Montana fly fishing trips on the Gallatin River with the team at Fins and Feathers Guide Service focus on the lower stretches. Floating the lower Gallatin River offers access to blue-ribbon trout waters that receive much less angling pressure than the upper river. Hazardous obstructions in the river are constantly shifting, making floating here more challenging than other rivers near Bozeman.
Trophy Rainbow and Brown Trout are here for the experienced angler willing to streamer fly fish during early summer days. Novice anglers quickly improve their skills as our guides patiently coach them through the intricacies of reading water and fishing near structures on this wild stretch of river.

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.
