Bighorn River Fishing in Montana's Chilly January: Tips for Nymphs, Streamers, and Staying Warm

If you're planning to hit the Bighorn River in Montana today, here’s what you need to know: First off, the weather is quite chilly, but that's typical for January. There's no tidal report to worry about since the Bighorn River is a freshwater destination, far from any oceanic influences. As of today, January 19th, the river flows are at 2,000 cubic feet per second, which is a good level for fishing. The water temperature is around 44 degrees, so make sure to bundle up. Sunrise today is around 7:50 AM, and sunset will be at about 4:45 PM, giving you a decent window to get some fishing in. Fish activity has been good, especially with nymphs and streamers. Brown trout are wrapping up their spawning season, but you can still catch some big rainbows and the occasional brown. Nymphs like #14 and #16 Orange Scud, Tailwater Sowbug, and #10 Squirmy Worm (in blood red or burgundy) have been producing well. For streamers, the “Goldie” (articulated white & gold), Thin Mint Wooley Bugger, and Dirty Hippie have been effective. If you're looking for some hot spots, consider the areas around the Afterbay and the upper stretches of the river. These spots tend to have deeper water where those big rainbows and browns like to hang out. Given the cold weather, it's best to use a sinking line in the deeper water to increase your chances of catching some larger fish. Midges are the only significant hatch right now, but they're not causing a lot of surface activity, so nymphing and streamer fishing remain your best bets. Overall, it's a great time to be on the Bighorn River, just make sure to dress warmly and be prepared for the cold.
