Winter Wonders on the Bighorn: Adapting to Chilly Conditions for Trout Fishing Success

As of December 6, 2024, the fishing scene on the Big Horn River in Montana is quite different from the warmer months, given the onset of winter. ### Weather and Conditions The weather in the Bighorn Mountains is chilly, with mostly cloudy skies and a chance of snow showers, especially after midnight. Lows are expected to be in the upper 20s, and southwest winds will be around 10 to 15 mph with gusts up to 25 mph[3]. ### Sunrise and Sunset For December 6, sunrise is at around 7:34 AM, and sunset is at approximately 4:43 PM[4]. ### Fish Activity Fish activity on the Big Horn River has shifted primarily to sub-surface fishing due to the colder temperatures. Most of the action is now with worms, sow bugs, perdigons, BWO nymphs, scuds, and midges. On overcast days, fish may still rise for BWO and midge dry flies[1]. ### Types and Amounts of Fish The Big Horn River is known for its healthy population of trout, including browns and rainbows. While specific catch numbers for yesterday are not available, the river typically holds a good number of fish, especially in areas with consistent structure and cover. ### Best Lures and Bait For this time of year, recommended flies include poxyback sow, yum-yum sow, Herford’s magic, various worm patterns, thin mints, midges, firebead sow, purple and pink lucent perdigons, black Spanish bullet, san juan worms, Sculpzilla, and Rusty Tombone. Streamers can also be effective for targeting aggressive browns[1]. ### Hot Spots - The upper sections of the Big Horn River, particularly around the 3-mile mark, can be productive for those targeting hatches, although this is less active in winter. - The lower sections of the river, which remain cleaner and less affected by grass growth, can be good spots for nymphing and streamer fishing[5]. Overall, the Big Horn River offers challenging yet rewarding winter fishing, especially for those willing to adapt to the colder conditions and focus on sub-surface techniques.
