Big Horn Montana Fishing Update: Trout Feeding Frenzy and Hatches Galore
Published 5 months, 3 weeks ago
Description
Artificial Lure here with your boots-on-the-bank Big Horn Montana fishing report for Saturday, November 8, 2025.
First light rolled in this morning at 6:59 AM and sunset will cap us off at 4:47 PM, giving anglers a brief but productive window for fall action. The Bighorn Valley’s been waking to frosty mornings—temps kicking off in the low 20s, climbing to highs around 46 by the afternoon, with mostly sunny skies and a steady breeze typical for early November according to Don Day’s Wyoming Weather Forecast. Water clarity’s prime, and flows are holding steady thanks to recent rain and a flush of colder air. According to the latest Montana Flow Report, the Bighorn River is running clear and near seasonal averages, with no flow drought issues currently complicating the bite.
Tides aren’t a factor out here—Big Horn’s a freshwater trout tailwater through and through—but water level steadiness keeps the fish settled in their fall patterns. With no drastic shifts, you can trust those trout are doing what trout do this time of year: bulking up before the chill takes full hold.
The activity’s been steady all week. Word from the bank is solid numbers of brown and rainbow trout, with a handful of anglers connecting on fish in the 16-20 inch range and some truly thumping browns pushing 22 inches. Recent days saw the fishiest runs outside of the Afterbay, down around Soap Creek, and stretches between 3-Mile Access and Bighorn Access. These classic spots are holding pods of trout in slow seams and gravel drop-offs. Local chatter backs up what I saw yesterday morning: persistent nymphers and patient streamer swingers are putting up steady tallies, with some reports of 20-trout days if you grind the holes.
This week, midges and baetis (blue-winged olives) are the main hatch, especially on those crisp overcast afternoons. Top subsurface producers? It’s tough to beat a two-fly rig—small red or black zebra midges (sz 18-20) trailed by a sow bug or firebead Ray Charles in tan or grey. If you like your bugs bigger, Czech nymphs and scuds (#14-16) have been popping some nicer rainbows. Bighorn regulars also report late-morning baetis nymphs in olive and grey (#18-20) are money just before a hatch.
Streamer junkies, this is your glory time: browns are hugging the structure, smashing gold and olive sparkle minnows, black woolly buggers, and peanut envy patterns, especially with a slow, steady retrieve and a little pause to trigger the take. Anglers casting near drop-offs and undercut banks have watched some true slabs shark after their fly. Don’t overlook flashy patterns, especially on those cloudier afternoons.
If you’re tipping toward bait, though most folks swing flies here, small leeches, nightcrawlers, and eggs are all classic fall producers below the Afterbay. Just remember to check regulations before baiting up, as special rules apply along several stretches.
Hot spots you’ll want to target this weekend? Swing by the usuals:
- Afterbay access: consistent with both nymphs and streamers in the deep runs by the dam;
- 3-Mile Access: strong numbers all week in the shallows and riffles;
- Soap Creek confluence: always a late-fall magnet for staging browns and opportunistic rainbows.
Surface activity is sporadic, but keep a dry fly handy if you see heads up—tiny parachute BWOs and Griffith's Gnats (sz 20-22) can fool the risers when the midday calm sets in.
No matter your style, afternoons are the sweet spot as water temps peak and trout get bolder, so plan your best hours between 10 AM and 3 PM. The banks will be quiet this time of year—perfect for taking in those Bighorn golds and reds.
