Bighorn River Late Winter: Clear Water, Strong Browns, and Midges at Midday
from Big Horn Montana Fishing Report Today · host Inception Point AI
Name’s Artificial Lure, checking in with your Bighorn country fishing report out of the Fort Smith / Big Horn, Montana stretch of the Bighorn River. River’s running clear and cold, classic tailwater green, with steady mid‑level flows below Yellowtail keeping the seams well defined. Overnight temps have been below freezing, with a warmup pushing into the upper 40s to low 50s by afternoon and a light south breeze. According to the National Weather Service out of Billings, we’re looking at a mostly sunny day, minimal chance of precip, and enough warmth to wake the bugs up mid‑day. Local almanac data puts sunrise just after 6:45 a.m. and sunset a little before 6:15 p.m., giving you a tight but very fishable window. No tides to worry about here, of course—just tailwater releases and a bit of afternoon gust. Fish activity’s been classic late‑winter Bighorn. The last couple days, local guides coming out of Fort Smith shops are reporting strong **brown** and **rainbow** trout action from Afterbay down through Bighorn Access, with most fish running 14–18 inches and a few heavy 20‑plus browns showing up out of the deeper buckets. Boats working nymph rigs are seeing 20–30 fish to hand on good drifts; wade anglers are doing a little less but still plenty busy if they stick to the soft edges. Subsurface is still the main game. According to several Bighorn shops’ online reports, **orange and pink scuds**, **ray charles**, and **sowbugs** in size 14–18 remain the staple patterns, paired with tiny **black midges** and **baetis nymphs** when the sun gets higher. Fish are sitting in the slow insides and drop‑offs first thing, sliding up into gentle riffles and seams late morning as the midge hatch ramps. A standard Bighorn nymph rig—9 to 11 feet from indicator to split shot, with 5X–6X tippet—has been the money setup. If you’re a dry‑fly diehard, keep your powder dry until late morning. When the wind lays down, pods of rainbows have been up on midges in side channels and foam lines. A #18–20 Griffith’s Gnat, midge cluster, or small parachute BWO will do work if you can get a drag‑free drift. Streamer folks are picking off fewer fish but bigger ones: small **olive or black buggers**, thin zonkers, and articulated patterns in muted tones stripped slow along the inside bends have moved some thick pre‑spawn browns. Gear and bait wise, this is a **flies‑only** style fishery for most of the prime stretch, so plan on artificial flies and lures rather than bait. Spin anglers doing the catch‑and‑release thing are doing well on small **marabou jigs**, **Panther Martins**, and **Rapala‑style minnows** in brown trout or rainbow patterns, worked slow in the deeper runs. If you venture to nearby warm‑water sloughs and private ponds off the valley floor, locals have started picking up a few **pike** and **walleyes** on frozen smelt, herring, and bright spoons as the ice pulls back, but ice conditions are variable—treat every step like it’s your first.
