Bozeman Fishing Reports

Winter has settled into the Bozeman area, and the colder nights are shaping how each river is fishing. Most mornings are pretty quiet with ice along the edges, but once the sun gets up and things warm around midday, there’s been a reliable fishing window across the valley. Water clarity remains good on all the major rivers, and angling pressure is light.
Gallatin River
The Gallatin is in full winter mode now. Ice shelves are forming in the canyon, and the best fishing is happening from late morning into the afternoon. Nymphing is the main approach with small stonefly patterns, zebra midges, and thin perdigons producing in the slower winter water. Streamers are a possibility during cloud cover, but nymphs are doing nearly all the work this time of year.
Lower Madison River
The Lower Madison remains one of the more dependable winter options. While the mornings are cold and slow, the river fishes well once the day warms up. Zirdles, crayfish patterns, worms, and small midges are all steady producers. Fish are holding tight to softer water and deeper slots. Streamers can still move a few trout on mild days, but the nymph rig is the go-to setup.
Upper Madison River
The Upper Madison is fishing as expected for December—best around midday with fish settled into the deeper, slower edges. Rubberlegs, stonefly nymphs, and small droppers like PTs, midges, or slim perdigons have been reliable. A few fish will still swipe at smaller streamers on warmer days, but conditions remain mostly nymph-focused.
Yellowstone River
The Yellowstone is showing typical early-winter conditions with ice building along the banks and some side channels starting to freeze. Nymphing with small stoneflies, attractor nymphs, zebra midges, and perdigons has been the most productive approach. Streamers are still an option during cloud cover, but it’s a slower game now. Dry-fly opportunities are rare.
Across the Bozeman area, winter fishing means aiming for the warmest part of the day and keeping things simple—deep nymphs, slower water, and short, controlled drifts. It’s quiet, predictable, and a good time to get out before the deeper freeze settles in.
