Gallatin River Fly Fishing Reports
Gallatin River Fishing Report 5/15/2021
The Gallatin River is on the rise and fishing will slow a bit as a result. The water still looks fishable at this point but that might not be the cases of tomorrow. Nymphing will be most consistent with worms, stonefly nymphs, Pheasant Tails and Lightning Bugs. In the right water, you may be able to find fishing rising to caddis adults. Try a Peacock Elk Hair Caddis to imitate adult caddis flies. A Parachute Adams or Purple Haze in sizes 12-18 should cover the mayflies. Small, olive streamers have also been getting it done.

The Gallatin should be fishing well this week with the warmer weather. Don't be surprised if it starts showing some color tomorrow or the next day. As the snow melts the river should get that nice Gallatin green going which almost always means good top fly fishing with rubberlegs and worms. A red copper john, or a zebra midge will be your better options for bottom flies. Streamer fishing with smaller dark streamers should also improve especially in the valley. As the temps increase keep a keen eye out for skwala and BWO adults as these will start to pop off over the next few weeks. Should be a decent amount of adult midges as well so be prepared for that.

Gallatin River Overview
The Gallatin River is one of the more scenic, blue-ribbon trout waters found in the Bozeman area. The river changes in character from a small mountain stream near its headwaters in Yellowstone National Park to a medium-sized, classic western river once it flows into the Gallatin Valley. The middle portion of the river flows through the Gallatin Canyon and is characterized by pocket water and swift currents. Once it leaves the canyon stretch, the river slows its pace with much of the trout water being found in a classic riffle, pool, and run water types. The Gallatin River is noted for having very clean, cold water throughout its course and served as the setting in which much of "A River Runs Through It" was filmed.
