This is Artificial Lure reporting from the legendary Yellowstone River, Montana, where late summer is offering up a classic mix of hot afternoons and cooling rains. Today, Wednesday, September 3, 2025, we saw sunrise at 6:44 AM and sunset will hit at 7:52 PM. Weather’s been mostly hot, with highs around 90 and intermittent east winds shifting west — plus a patch of clouds rolling in by late afternoon. River flow near Miles City’s about 8,930 cfs; a slight bump up from yesterday, keeping things lively after those late August rains helped recharge soil moisture and cool down the water just enough to open more fishing stretches after a tough summer of restrictions according to Snoflo and Montana Outdoor.
Fishing pressure is easing most mornings, but “hoot-owl” restrictions remain for the Madison and the stretches in Yellowstone National Park. That means no fishing from 2 p.m. to midnight, all to reduce stress on trout during peak heat — and the same logic applies here on the Yellowstone: get out before lunch, handle fish quick, and keep ‘em wet for a strong release, per Montana Fish, Wildlife & Parks.
Now, for fish activity: Recent days brought solid reports of chunky rainbow trout and native cutthroat, especially near Livingston and Paradise Valley, where water temps flirted with 60°F early but rise sharply by midafternoon. Even browns are getting active, tucking into the deeper seams and cut banks where the flow stays cool. The area around Pine Creek and Emigrant remains prime for both numbers and size. The best bite has come at first light or after dinner; midafternoon action tapers sharply.
As for techniques, this week’s best lures have been:
- Chubby Chernobyls in purple or peacock on mid-sized dry-dropper rigs.
- Pat’s Rubberlegs in black or brown for deeper nymphing.
- Copper Johns and Lightning Bugs trailed behind for picky fish staring down small mayfly nymphs.
- Streamers like the Circus Peanut or classic Woolly Bugger—especially in olive or black—are drawing bigger browns at dusk and dawn.
If you’re fishing conventional tackle, small spinners—Panther Martins in silver or gold—have turned up surprises, especially with brighter sun. For bait, it’s hard to beat locally sourced nightcrawlers in the muddy slower sections, but remember, artificial only in the park!
Hopper season’s winding down, but there’s still enough warmth that hot afternoons bring fish up for a good grasshopper dry — especially in the open meadows near Mallard’s Rest and the far flats west of Pine Creek.
Recent catches have included steady limits of rainbows and a handful of browns pushing 19 inches near Emigrant. The water’s up enough that boats are getting down as far as Big Timber, with solid streamer action and even a rumor of a 22-inch cutthroat pulled near Springdale just yesterday.
Hot spots for the next couple days:
- Paradise Valley at Pine Creek — for early morning trout feeding on terrestrials and nymphs.
- Emigrant Flats — deeper runs and seams are stacked with feeding browns and rainbows as flows hold steady and temps stay cooler.
One last note: be on the lookout for smoky haze drifting over from regional fires. Air’s clear right now but could shift, so keep an eye on visibility and pack some extra water. The river’s fishing strong, restrictions are easing, and with careful handling, these native fish will still be here next season.
