Bighorn Wintertime Trout: Nymphs, Midges, and Streamer Tactics for Big Browns and Bows
Published 3 months, 3 weeks ago
Description
This is Artificial Lure coming to you from down on the Bighorn.
We don’t have tides out here in Big Horn, just the steady pull of Yellowtail Dam, and flows have been running on the low, clear side typical of mid‑winter, which keeps the river wadable but makes the fish a little spooky according to local fly shops in Fort Smith. Sunrise is right around 8 a.m. and sunset about 4:45 p.m., so you’ve got a tight window of real productivity centered late morning to mid‑afternoon when the water bumps a couple degrees.
Weather today around Big Horn is classic cold‑season tailwater stuff: teens to low 30s at night, climbing into the upper 30s to low 40s under mostly cloudy skies with light wind, based on National Weather Service point forecasts for the Bighorn River corridor. That faint bit of warmth is enough to slide a midge hatch into gear if the clouds hang in.
According to the latest Bighorn River fishing report from Montana Outdoor and regional outfitters, the river is fishing better than you’d expect for winter. Nymphing is “hot” by January standards, and fish counts remain very strong, with the typical Bighorn mix of **brown trout** and **rainbows** in the 14–18 inch class, plus an honest shot at fish over 20 inches on most floats. Anglers this past week have been putting double‑digit numbers in the net on good days, mostly on subsurface rigs.
Fish activity is concentrated in the softer seams and slower winter runs. You’ll want to forget about the fast riffles and instead work the walking‑pace water: inside bends, drops below shelves, and deep buckets at the tailouts. Trout are hugging the bottom, so add weight until you’re just ticking rocks every few drifts.
Best patterns right now:
- **Nymphs:** Zebra midges (black, red) in 18–20, Ray Charles in tan or grey 16–18, sowbug patterns, and small mayfly nymphs like Pheasant Tails in 18. A pink or orange scud as a lead fly has been a quiet producer too.
- **Dry flies:** When heads show, it’s mostly midges. Go with a Griffith’s Gnat or small cluster midge in 18–20, long leader, 5X or 6X, and keep the cast short.
- **Streamers:** On the slower, overcast stretches, a small articulated minnow like a sparkle minnow or thin-profile olive/black streamer swung low can draw a few big browns. Strip slow and keep it near the bottom.
Best “lures” if you’re spin‑fishing:
- Small **marabou jigs** in olive or black.
- Tiny **spinners** in silver or gold.
- 2–3 inch **minnow plugs** in natural trout or sculpin colors.
Tip with a bit of nightcrawler if regulations and ethics allow where you’re fishing; check the current Montana Fish, Wildlife & Parks rules for the specific reach.
Natural bait (where legal) is classic winter fare: **maggots, waxworms, or small pieces of worm** drifted under a float tight to the bottom. Keep everything small and subtle; these Bighorn fish see a lot of pressure.
A couple local hot spots to focus on:
- **Afterbay to 3‑Mile:** That upper tailwater reach has been consistent, with good numbers of both browns and bows on sowbugs and midges. The deep bends below the Afterbay access are prime winter holding water.
- **Bighorn Access to Mallards:** Longer float, but those mid‑river shelves and soft inside turns have been producing some of the better‑quality browns on nymphs and the odd streamer.
Fluorocarbon 4X–5X, long leaders, and a quiet approach are the difference between “decent” and “lights out” right now. Take your time, fish methodically, and you’ll find ’em.
