Bighorn River Fly Fishing Forecast: Abundant Trout, Ideal Conditions for Anglers This Fall

As of October 17, 2024, the Bighorn River in Montana is offering some excellent fly fishing opportunities, despite the transitioning seasons. ### Weather and Time The sunrise today is at about 7:45 AM, and the sunset will be around 6:15 PM. The weather is expected to be cool, especially in the mornings and evenings, with daytime temperatures in the mid-50s to low 60s. ### Water Conditions The Bighorn River is a tailwater fishery, and its flow is currently stable at around 2,500 cubic feet per second (CFS). The water temperature is around 59 degrees, which is ideal for trout activity. However, aquatic grass is still present in some areas, particularly in the upper sections, so it's crucial to look for clean lanes to fish. ### Fish Activity Fish activity has been good, especially subsurface. Trout are actively feeding on worms, scuds, and other nymphs. The dry fly action has slowed down, but there is some caddis activity in the evenings, and a few tricos can still be seen. ### Types and Amounts of Fish The Bighorn River is home to large and healthy populations of Rainbow and Brown Trout. Yesterday, anglers reported catching several nice-sized trout using subsurface patterns. The fish are spread throughout the river, but the section from the dam to the Bighorn Access is particularly productive. ### Best Lures and Bait For nymphing, San Juan Worms in wine or blood red colors are highly effective. Other recommended patterns include Tailwater Sowbugs, Carpet Bug Sowbugs, and Ray Charles in grey or tan. For streamer fishing, articulated patterns like the Jig Thin Mint, Pete’s Buggers, and Rusty Trombones are working well. If you're looking to try dry flies, Black Micro Mayflies, Pearl/Olive Jiggy Perdigons, and small peacock elk hair caddis can trick the fish. ### Hot Spots One of the best spots to fish is the section between Afterbay and 3-Mile Island. This area offers a mix of fast and slow water, making it ideal for both nymphing and streamer fishing. Another hot spot is the Bighorn Access area, where the river widens and slows down, providing ample opportunities for catching trout. Overall, the Bighorn River is in great shape for fall fishing, with plenty of fish to target and a variety of effective fly patterns to use. Just be sure to keep your flies clean due to the breaking aquatic grass. This content was created in partnership and with the help of Artificial Intelligence AI.
