Bighorn River Fishing Report: Excellent Fall Conditions Await Anglers on Montana's Premier Trout Stream

As of October 11, 2024, the Bighorn River in Montana is offering some excellent fishing opportunities despite the transitioning fall season. ### Conditions The water flow is currently around 2500 cubic feet per second, which is ideal for both wading and floating. The river is clear, though there is some grass growth, particularly in the upper sections, which can make nymphing a bit challenging. However, the cool nighttime temperatures are helping to break up this grass, making it more manageable. ### Weather The weather is cooling down, with nighttime temperatures dropping significantly, which has put the fish in a better mood. Expect clear skies with some cloud cover, especially in the afternoons, and temperatures ranging from the mid-50s to low 60s. ### Sunrise and Sunset Sunrise is around 7:30 AM, and sunset is approximately 6:30 PM, providing a good window for fishing. ### Fish Activity Fish are actively feeding, especially subsurface. Tricos are still present, but the fish are more inclined to feed on subsurface flies. Streamer fishing is picking up, with larger fish starting to move into the system as the fall season progresses. ### Types and Amounts of Fish Brown trout are the primary target, with many healthy fish throughout the entire Bighorn River system. Anglers have been catching a good number of browns, particularly on streamers and nymphs. ### Best Lures and Bait For subsurface fishing, worms, Dorsey’s Scud, Carpet Bugs, and Tailwater sows are working well. Streamers like Jig Thin Mints, Pete’s Buggers, Goldies, and Rusty Trombones are also effective. On the surface, Tricos and Black Caddis are still attracting some fish, but the action is more sporadic. Black Micro Mayfly, Pearl/Olive Jiggy Perdigon, and Black Zebra Midge are also recommended. ### Hot Spots The upper three miles of the Bighorn River have consistent hatch activity, especially around 11:00 AM till dark. Below 3 Mile, the river offers good streamer fishing and subsurface action. The shallow riffles and deeper runs are both productive, depending on the time of day and the type of fishing you prefer. Overall, the Bighorn River is in great shape for fall fishing, with plenty of opportunities to catch some big and healthy brown trout. Just be sure to keep your flies clean due to the occasional grass break-off. This content was created in partnership and with the help of Artificial Intelligence AI.
