Bighorn River Fishing: Adapt and Conquer the Changing Conditions for Rewarding Trout Action

As of December 1st, the Bighorn River in Montana is offering some challenging yet rewarding fishing conditions. Here’s what you need to know: ### Weather and Water Conditions The weather remains surprisingly pleasant for this time of year, with highs expected to reach into the mid-50s. However, the water clarity is still a bit off due to aquatic grass breaking off and floating downriver, though the river is slowly cleaning up[2][4]. ### Sunrise and Sunset Sunrise today is at around 7:30 AM, and sunset will be at approximately 4:30 PM. ### Fish Activity Fish activity is varied, with nymphing being the most reliable method. The fish are more inclined to feed subsurface, especially on scuds, sowbugs, and worms like the San Juan Worm in wine or blood red colors. Streamer fishing is also picking up, with patterns like Thin Mint Wooley Bugger, Articulated Goldy, and Rusty Trombone working well[2][4]. ### Types and Amounts of Fish There are plenty of big, healthy fish throughout the entire Bighorn River system. While the numbers might not be as high as in clearer water conditions, you can still catch some sizable trout. Brown trout and rainbow trout are the primary species being targeted[1][2]. ### Best Lures and Bait For nymphing, use flies like Orange Scud, Tailwater Sowbug, Carpet Bug Sowbug, and Squirmy Worms. Streamers such as Thin Mint Wooley Bugger, Articulated Goldy, and Rusty Trombone are effective for targeting larger predatory fish. Dry fly action is limited, but some Blue Winged Olives (BWOs) and midges are hatching, though not many fish are looking up[2][4]. ### Hot Spots The upper 3 miles of the Bighorn River has consistent hatch activity, although it has some grass growth. Below this section, the river remains clean and fishes well. Focus on areas below the Afterbay, where the water is clearer, and around the 3 Mile mark, where you can find good subsurface action[1][4]. Overall, while the fishing might be a bit tougher due to reduced water clarity, the Bighorn River still offers great opportunities for those willing to adapt their tactics.
