Gallatin River Fly Fishing Reports
Gallatin River Fishing Report 4/28/2021
The Gallatin is running clear and we have seen some good BWO and March Brown hatches the last few days. If you watch the slower moving slicks expect to see a few fish rising. We have been tricking these trout with small olive or grey parachute patterns. The best fishing is still being had with nymphs. Run a Pat's Rubberlegs or a worm as a top fly with a Prince Nymph, Copper John, Midge, or Pheasant Tail off the back. Fish the slow and deep stretches consistently. Most of the fish will be hanging out in these areas so if you aren't catching fish in a good looking spot, mess around with your leader length and weight on your nymphing rig. Streamer fishing has been hit or miss but with the overcast in the forecast, this should pick up. Fish a small black or olive pattern that has some weight to it and see what happens. Given this week's forecast we expect to see caddis and color in the river by the end of the week.

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.
