Artificial Lure here with your Yellowstone River fishing report for Monday, October 27, 2025.
October’s rolled in strong and the Yellowstone’s full of what makes Montana fall special—cold mornings, gold on the cottonwoods, and rainbows that can’t seem to leave a streamer alone. According to Montana Outdoor’s most recent update, we’ve got clear water and aggressive fish activity from Livingston right on down the valley. Flows are steady but lean, typical for late season, making it easy to read the seams and chase those deeper runs where the browns are staging up for the fall spawn. Recent rains spurred a Blue Wing Olive (BWO) hatch, so there’s life on top and under the surface. Air temps this morning are crisp—expect low 30s at sunrise, warming toward 50 by afternoon. Winds have been light in the early hours, though keep an eye out for breezes out of the west around lunch. Visibility’s outstanding after the rains cleared silt, and with sunrise at 7:48 AM and sunset near 6:19 PM, you’ve got a solid window for chasing trout. Tides aren’t a factor on the Yellowstone, but major fish activity today, according to FishingReminder, peaks in the late morning and again around 4:30 PM, so plan your outings for those slots if you can.
The bite has come alive after a quiet stretch—Montana Fly and Lake Fishing Reports note hungry rainbows and the first push of brown trout moving up from deeper holes. Most days have seen solid numbers—anglers pulling in a mix of 12–18” rainbows and a decent showing of browns over 20”, especially on the stretch between Pine Creek and Carter’s Bridge. Nymphs and streamers are king right now: try a black or olive Woolly Bugger, a white sculpin pattern, or if you’re nymphing, a trusty Pheasant Tail or Prince. The BWO hatch means you might get a chance to fish dries if there’s some cloud cover, so keep a few size 18–20 BWO patterns in the box. For those not chucking flies, a gold or copper Panther Martin or a Mepps Spinner has accounted for some surprise cutthroat near the slower runs below Livingston.
If you’re bait fishing (where permitted), nightcrawlers drifted deep through the seams have picked up chunky rainbows. Egg patterns are a must with browns on the move; drop them off a heavier nymph for tandem action.
Hot spots to focus on today? I’d zero in on the DePuy’s Spring Creek confluence—just outside Livingston—which has been producing big fish from both the creek and main river channel. Pine Creek Bridge is also a local’s favorite for both wade and drift fishing, especially with less pressure this late in the month. If you’re willing to make the hike, the stretch below Emigrant has quiet pockets and braided channels loaded with fish that haven’t seen much traffic.
Other notes: Wildlife is active—keep bear spray handy, especially if you’re off the main accesses or fishing early and late. Local news from KLTZ reminds folks about blue tongue outbreaks along the Yellowstone corridor affecting some prairie wildlife, but trout and river action remain prime.
