Yellowstone River Fly Fishing Report
Current Yellowstone River Fishing Report
Updated 09/03/2026
Current Flow: ~ 2000 CFS at Livingston & 1720 CFS @ Corwin Springs
The Yellowstone River has been fishing well when you can find the clean water. We’ve still had some random pushes of color coming through from recent rainstorms, especially depending on what happens up in Yellowstone National Park and around tributaries like the Lamar. Some stretches can look pretty dirty while another section farther upstream or downstream might be completely fishable, so it’s definitely worth checking conditions before committing to a section. If we get a stretch of drier weather, the river should continue to clear and become more consistent going into September.
Terrestrials are still very much in play right now. Hoppers, ants, and beetles have all been getting looks, and smaller hopper patterns or attractor dries with a dropper underneath are still a great way to cover water. There have also been some Tricos around, especially farther downriver, and we’re starting to get into that time of year where Blue-Winged Olives and Baetis should become a bigger part of the program as the weather cools. Underneath, rubber legs, Pheasant Tails, Princes, Perdigons, caddis nymphs, and smaller Baetis-style patterns are all good options. If the river has a little bit of color, don’t be afraid to fish a slightly larger stonefly, rubber leg, or sculpin-style pattern with a smaller dropper behind it.
Streamer fishing has also started to become a really good option, especially when there is some color in the water, cloud cover, or during the lower-light parts of the day. Small to medium sculpin and baitfish patterns have been working well, and this is a great time of year to start looking for some of those better brown trout. Olive, black, white, and natural-colored streamers are all worth having in the box, and you can experiment with everything from a quicker strip to a slower swing or lightly stripped retrieve. Overall, the Yellowstone is heading in a good direction for September. The biggest thing right now is staying flexible, watching the weather, and finding the stretch of river with the best clarity on any given day.
Learn More About Fly Fishing the Yellowstone River
The Yellowstone River is one of the most iconic and productive trout fisheries in Montana. As the longest undammed river in the lower 48, the Yellowstone provides constantly changing conditions shaped by weather, flows, and seasonal runoff, creating a dynamic fishery that rewards anglers who adapt day to day.
Flowing through Paradise Valley near Livingston, the river supports healthy populations of wild rainbow trout, brown trout, and native Yellowstone cutthroat trout. From large riffles and deep runs to side channels and cutbanks, the Yellowstone offers diverse water types that fish well with a variety of techniques—from nymphing and dry flies to streamer fishing.
Where to Fish the Yellowstone River
The most productive stretches of the Yellowstone River run from Gardiner through Paradise Valley and down past Livingston. Sections like Yankee Jim Canyon offer rugged, technical water with strong fish, while the valley stretches provide broader runs, gravel bars, and classic bank structure that hold trout throughout the season. As you move downstream, the river transitions from higher numbers of cutthroat trout to a mix of larger rainbow and brown trout, offering different opportunities depending on where and when you fish.
