Bighorn River's Winter Trout Bonanza: Top Lures, Spots, and Tips for Cold-Weather Fishing Success

As of January 18, 2025, the Bighorn River in Montana is offering some excellent fishing opportunities despite the chilly winter conditions. ### Weather and Water Conditions The weather is quite cold, with temperatures around 44 degrees Fahrenheit in the water and air temperatures expected to remain low. Arctic air is plunging across the region, bringing gusty winds and potentially reduced visibility due to snow squalls[2]. The river flows are currently at 2,000 cubic feet per second (cfs), which is relatively stable and favorable for fishing[1]. ### Fish Activity The fish are active, particularly in the deeper slots where the water is cooler. Brown trout are nearing the end of their spawning season, but there are still plenty of big, healthy rainbows and the occasional brown trout to be caught[1][3]. ### Sunrise and Sunset Sunrise today is around 7:45 AM, and sunset will be approximately 4:45 PM, giving you a good window for fishing. ### Best Lures and Bait For nymph fishing, scuds and sowbugs are the primary producers. Try using #14, #16 Orange Scud, #14, #16 Tailwater Sowbug, or #16 Carpet Bug Sowbug. S.J. Worms, especially in blood red or burgundy, are also working well. Other effective nymphs include #16 Frenchie (gold bead, orange color) and #14, #16 Ray Charles (grey or tan)[1][4]. Streamer fishing is solid, with recommendations to use a sinking line in the deeper water. The “Goldie” streamer (articulated white & gold) has been particularly effective. Other good streamer options include #6 Thin Mint Wooley Bugger, #4 Dirty Hippie (cream), and #4, #6 White Zonker[1]. ### Hot Spots Focus on the areas closer to the dam where the water is clearer and the fish are more concentrated. The upper sections of the river have some grass growth, but everything below remains clean and fishes very well[3]. ### Additional Tips Be cautious of the cooler night-time temperatures which are causing grass to break off, but this should clear up as you head downstream. Subsurface fishing has been stellar, with lots of big healthy fish throughout the entire Bighorn River system[3]. Overall, the Bighorn River is in good shape for winter fishing, with plenty of opportunities to catch some big rainbows and browns using the right lures and techniques.
