Autumn Bite on the Bighorn: Montana Trout Fishing Report
Published 6 months ago
Description
Fishing fans, it’s Artificial Lure reporting on a spectacular late-October morning here around Big Horn, Montana. The chill of fall is in the air, and today’s sunrise painted the valley at 7:43 AM, while sunset will slip below the horizon around 6:07 PM—plenty of prime fishing hours, especially with these crisp, calm conditions.
Weather this morning is downright autumnal: expect cool temps starting in the low 30s at dawn with a promise of sunshine by midday, highs pushing into the mid-50s. Dress in layers and stay nimble, since the Bighorn’s notorious for shifting breezes as afternoon clouds build. There’s no saltwater tide near here, but river flows are steady, clarity is up, and October water temps have dropped just enough to spark both trout and angler activity, according to the most recent Bighorn River Fishing Report from Montana Outdoor[Montana Outdoor].
Fish are fired up as the water cools—brown trout are getting into their pre-spawn mood and chasing streamers aggressively, especially in the deeper runs and riffles downstream from Afterbay. Rainbows are stacked up in the seams, feeding steadily. Nymphing remains reliable: locals are swinging firebead sowbugs, orange scuds, and a size 16–18 zebra midge under indicators around Three Mile and Bighorn Access. For streamer anglers, something flashy—think olive or white Sparkle Minnows and slim-profiled Peanut Envys—has turned good heads. Mid-morning and late afternoon have delivered the steadiest takes this week.
Reports from up and down the river say folks are bringing double-digit days, especially drifting the standard 2-fly rig. Numbers are strong, with most fish in the 14–18" slot, though a handful of thick browns over 20" have been pulled from deeper cuts and behind gravel bars. For fly-chuckers, two hot patterns stand out: the purple San Juan worm and thin mint buggers. Live bait isn’t permitted on most Bighorn stretches—be sure to check local regs—but for spin anglers, small silver Panther Martins and black/gold Rapalas are producing just below the dam. If you’re set on numbers, try the upper flats at dawn with micro-jigs.
If you’re bringing the family or hoping for dinner, rainbow trout are the most consistent keepers right now, with a smattering of brown trout showing up for those exploring the sloughs. Several anglers this week have netted smallmouth bass near the edges as the sun warms shallow water in the afternoons, and, rumor has it, a couple of chunky pike are lurking in the backwaters as weeds die back.
Top hotspots: the Afterbay-to-3-Mile section is stacked with active fish and less pressure than mid-river, while Bighorn Access to Soap Creek is lights out right now for browns on streamers. Don’t overlook the braided stretches around Mallard’s Rest in the morning, and if you want a little solitude, sneak off to the islands above Soap Creek to pick off risers on nymphs.
For gear, a 6-weight rod for streamers or a 4–5 weight for nymphs gets it done. Short 4x fluorocarbon is plenty—these fish have seen a lot this year, but a low-profile approach still pays dividends.
This week in Big Horn, with golden leaves dropping and river traffic thinning, the fish are hungry and aggressive—perhaps the best action of autumn. Get out before the next cold snap locks things up!
