Yellowstone River October Fishing Report - Hot Trout Action Before Winter Chill
Published 6 months, 1 week ago
Description
Morning anglers, this is Artificial Lure coming to you with your fresh-off-the-bank Yellowstone River fishing report for October 20th, 2025.
It's a brisk and clear fall day in Yellowstone County, Montana, with temps starting off in the mid-30s and climbing to a high near 60 by noon. Sunrise hit at 7:36 AM, lighting up those cottonwood banks just as I got the thermos brewed. Sunset’s set for 6:21 PM, so you’ve got a solid window to wet a line. We’re far enough inland there’s no tidal influence, so nothing to worry about there.
Right now, every bend of the river is showing off autumn gold, and so are the trout. Water levels are slightly below average for this time of year, running clear in most stretches, with just a bit of leaf debris coming down from the wind late yesterday. The river’s holding steady at around 50°F—a sweet spot for those browns and rainbows to feed up before the hard chill settles in.
Fishing’s been hot the last few days, especially with the cooler nights. According to word from the fly shop in Livingston, anglers are seeing strong action in the riffles and deeper runs. Browns are definitely on the prowl, prepping for the tail end of spawning, while rainbows are starting to thicken up for winter. A few late-season cutthroat have also been reported—most of them were small, but still a thrill on light tackle.
The bite’s been best right after dawn up until about 11 AM, and then again from 4 PM through dusk. Folks drifting between Pine Creek Bridge and Carter’s Bridge reported steady hookups on streamer patterns—think olive or black woolly buggers, articulated sculpins, and smaller muddler minnows. Spin anglers are having luck with classic silver or gold Panther Martin spinners and Rapala countdowns, especially in the slower deep edges.
If you’re fishing bait, you can’t go wrong with nightcrawlers or fresh-cut sucker under a slip float, particularly around the undercut banks. For fly fishers, blue-winged olives have been coming off in good numbers mid-morning. Size 18-20 BWO dries and emergers have produced some exciting topwater eats during the hatch windows. Don’t forget small stonefly nymphs and pheasant tails in tandem with a little weight if you’re getting down deep—those bigger trout are foraging hard before winter.
The hottest spots right now? Give the stretch below Mallard’s Rest a try—there’s plenty of structure and pools, and the browns have been stacking up. Downstream, the islands near Yankee Jim Canyon are also fishing well, with quality fish pulled out of the deeper channels.
Montana Fish, Wildlife & Parks reports that recent surveys turned up healthy numbers, especially of browns in the 16–20 inch range and rainbows averaging 14–16 inches, with some pushing 20. A few lucky anglers even claimed chunky whitefish for a bonus fry-up.
A reminder: Respect the spawning redds—step lightly and fish the deeper water to avoid trampling the next generation.
That’s the word from the river today. Tie on something flashy, layer up, and enjoy this last burst of fall fishing. Thanks for tuning in, and don’t forget to subscribe for your daily updates. This has been a quiet please production, for more check out quiet please dot ai.
