Bighorn River Winter Trout Report: Steady Flows, Cooperating Trout, and Nymphing Tips
Published 4 months, 1 week ago
Description
Name’s Artificial Lure, checking in with your Bighorn country fishing report from down here around Fort Smith and up toward Hardin.
We don’t worry about tides on the Bighorn – she’s a tailwater, not salt – but we *do* care about that bottom‑release flow. The Bureau’s keeping things steady and cold, which is why this river fishes so well straight through winter. USGS gauges show clear, stable water and wade‑friendly flows most days right now.
Weather-wise, we’ve slipped into full winter mode. Mornings are starting out well below freezing with light wind, then warming just enough by late morning to make it comfortable if you’re layered up. Skies are mostly overcast with occasional sun breaks – classic winter bug weather. Sunrise is just after eight a.m., sunset a little before five; real fishing window is about 10 to 3 when fingers still work and the trout wake up.
According to the recent Bighorn River report from Montana Outdoor, it “isn’t pretty out there, but the trout are cooperating,” and that’s dead on. Fish are stacked in the softer winter water: deeper buckets, inside bends, and slow seams below riffles. Nymphing is king. Think small and sparse:
- Best flies: size 18–22 midge patterns (zebra midges, cream and black), tiny mayfly nymphs like thread baetis and pheasant tails, plus an occasional tan or brown sowbug or scud as your lead fly.
- Rigs: 9–10 foot leaders, 4X to 5X fluoro, enough split shot to tick bottom, and an indicator set just above twice the depth.
- Presentation: short drifts, high‑stick, mend early and let it ride.
Streamer bite is there in short bursts when the clouds roll in and temps bump up. Smaller sculpin and leech patterns in olive, black, or natural, swung slow off the bank, are moving some nicer browns. No need for giant meat; keep them compact, unweighted or lightly weighted, and use a sink‑tip or long leader to get down.
Dry‑fly game is limited but not dead. Watch for mid‑day midge clusters in the softer slicks below Afterbay and 3‑Mile. Griffith’s gnats, buzzballs, and tiny CDC midge emergers on 5X–6X will pick off picky risers if you’re patient.
Recent catch reports from local shops and guides around Fort Smith all sound similar: plenty of 14–18 inch rainbows with a sprinkling of 18–22 inch browns showing up for folks who grind the deeper runs. Numbers are strong if you stay in the winter water and don’t hop around too much.
Bait folks working downstream closer to Bighorn and Hardin on the lower river are finding some action with:
- Best bait: nightcrawlers drifted deep, salmon eggs, and the occasional minnow where legal.
- Hardware: small silver and gold spoons, Panther Martins, and marabou jigs slow‑rolled through the deeper bends.
Couple of local hot spots to circle:
- **Afterbay to 3‑Mile**: Classic winter float. Deep green runs and buckets are loaded with bows. Work every inside turn thoroughly.
- **Below Bighorn Access down toward Mallards**: Fewer people, good structure, and some bigger browns for those willing to cover water with streamers and nymphs.
If you’re bank fishing, focus on the soft edges just off the main current and any deeper slots tight to the bank. Don’t overlook that last hour of light – as the sun drops behind the canyon walls, fish often slide shallower and the bite can pulse one more time.
That’s the word from Bighorn country today. Thanks for tuning in, and don’t forget to subscribe so you don’t miss the next report.
