Winter Fishing on Montana's Bighorn River - Nymphs, Streamers and Tactics for Cold Weather Trout
Published 4 months, 2 weeks ago
Description
Name’s Artificial Lure, checking in with your Bighorn Country fishing report out of the Big Horn, Montana neighborhood.
We don’t worry about tides here on the Bighorn; this is tailwater country below Yellowtail, so flows and temps out of the dam matter more than any ocean chart. The river’s running clear and cold, classic early‑winter conditions with a narrow window of prime action late morning through mid‑afternoon as the air warms a touch. Local shop chatter in Fort Smith says fishing has been steady for folks who slow down and fish deep.
Weather today around Big Horn is sitting on the cold side, single digits to low teens at daybreak, climbing into the 20s with light wind and high clouds. According to the National Weather Service, we’ve got mostly cloudy skies, just enough cover to keep the trout comfortable. Sunrise is right around 7:50 a.m., sunset near 4:25 p.m., so you don’t get many hours — plan to be on your best water from about 11 to 3.
Fish activity: it’s full-on winter mode. Recent reports from Montana Outdoor and local Bighorn guides say the nymph bite has been the main show, with midges and small mayfly nymphs doing most of the work. Browns have wrapped up spawning and are settling back into slower edges, while rainbows are parked in the softer guts of the runs. Expect subtle takes; if your indicator twitches, set.
What’s been caught lately: anglers are still putting decent numbers of 14–18 inch rainbows in the net, with a sprinkling of browns up to the low 20s. Boats running from Afterbay down through 3‑Mile have been seeing the best consistency, a dozen or more fish to the net on good days, fewer when the temps really clamp down. Wading anglers near the Afterbay outlet have reported solid half‑day sessions with mid-teens fish and the occasional thick brown.
Best winter rigs right now are:
- Nymphs: tiny stuff. Think size 18–22 zebra midges in black, red, and olive; thread midges; small sowbugs and scuds; black Beauty-style patterns; and slim baetis nymphs like Barr’s BWO or little Frenchies. Run a two‑fly rig under an indicator with plenty of weight — your flies should tick bottom.
- Streamers: if you’re hunting a bigger brown, swing or slowly strip small olive or black leeches, Thin Mints, and slim sculpin patterns on a sink tip. Keep the retrieve painfully slow.
- Bait: on the nearby Bighorn Lake and local ponds where bait is allowed, small fathead minnows, waxworms, and mealworms under a slip bobber are taking perch and the odd walleye through early ice. Always double‑check regs; the main Bighorn tailwater is artificial‑lure‑only, no bait.
Presentation is everything now. Short drifts, tight mends, and a sensitive indicator will out‑fish fancy patterns. Fluorocarbon 5X–6X tippet is standard; go lighter only if you must.
A couple of local hot spots to focus on:
- The classic stretch from **Afterbay to 3‑Mile**: work the inside seams, drop‑offs below riffles, and any slow, waist‑deep walking‑pace water. Don’t waste energy in fast stuff; fish are glued to softer lanes.
- The **Police Hole and surrounding runs below 3‑Mile**: deeper wintering water where fish stack up. Hit the heads and tails of the big buckets with nymphs, then swing a small leech across the middle.
Ice is forming along the edges and in back eddies, so wade carefully. Felt or studs and a wading staff aren’t optional right now.
That’s the word from the river. Thanks for tuning in, and don’t forget to subscribe so you don’t miss the next report.
