November Chill on the Bighorn - Trout Tactics for Montana's Famed River

Fishing community, this is Artificial Lure with the angler’s update for November 2nd, 2025, reporting from Big Horn, Montana, and the iconic Bighorn River. We woke to a crisp 29°F under overcast skies as daylight crept over the Pryor Mountains, with sunrise pegged at 7:00 AM and sunset wrapping it up at 5:51 PM. Montana is bracing for a wintry day: weather advisories are in effect, and forecasters warn of a wet snowstorm dropping up to four inches in the region. Winds are expected to gust up to 35 mph at times, adding a real bite to the chill. Bundle up and mind those snow squalls, especially along the riverbanks and open roads. Water flows on the Bighorn below Yellowtail Dam are moderately strong for November, with most Montana rivers averaging about 72 percent of their normal levels according to SnoFlo’s statewide streamflow report. That means the Bighorn should be running stable with a slight bump, perfect for targeting those deep, slow pools and inside bends. No tides to report for these inland rivers, but moon phase is waning gibbous, which often encourages afternoon activity, especially for browns with the spawn underway. Yesterday and into the early hours, guides and walk-in regulars reported solid numbers of rainbow trout in the 15–18 inch class, with browns caught pushing 20 inches, especially near the “Afterbay” and “3 Mile Access” stretches. Best productivity came early and again late afternoon, as the sun struggled to break through those thick November clouds. Hot lures and baits this week have leaned classic: - For spin fishermen, small silver and gold spoons like the Panther Martin or Mepps did the trick, as did soft plastic minnows in white or pearl. - Fly anglers landed most fish on nymph rigs: sowbugs, pink and orange scuds, and Ray Charles in size 16, trailed by smaller midge pupae. - Streamers—especially black or olive Woolly Buggers and sculpin imitations—moved the truly heavy browns, especially close to dusk. - For those bait fishing, fresh nightcrawlers on the bottom or a single salmon egg below a split shot saw some quality takes where regs allow. Hot spots this week? Don’t miss the classic “Afterbay to 3 Mile” float, targeting seams and tailouts. Wading anglers have done best in the soft water below the dam and at “Bighorn Access,” focusing on slower currents outside the main channel. If you’re hunting a trophy, the area near Soap Creek’s confluence is notorious late fall territory. Fish are hanging a little deeper with the cold and extra flow, so get your presentations down and don’t be afraid to dredge. Expect trout to hit soft—watch that line for gentle takes. Word is, the big browns are still active on the spawn, so remember to respect their redds and practice good river stewardship. Montana’s unpredictable November elements are in full swing, so dress for ice in your rod guides and keep an eye out for quick changes in both weather and water.
