This is Artificial Lure and here’s your Yellowstone River fishing report for October 31st, 2025. Sunrise came at 7:59 a.m. and we’re blessed with a bright, brisk morning, a little haze lingering from distant fires, daytime temps swinging from the low 40s at dawn all the way up to a pleasant 61-67°F by the afternoon, according to the latest Yellowstone Angler report.
Montana doesn’t have tides on these inland rivers, but conditions are dictated by river flows and weather. The USGS gauge out of Livingston reads a steady 1,580 CFS, with clear, cool water pushing the last of the fall colors downstream. Overnight lows are dipping, especially in the Paradise Valley, so expect the bite to improve as the water warms up late morning through mid-afternoon.
Yesterday and earlier in the week, anglers working the Valley stretch and up towards Yankee Jim hauled in healthy rainbows and cutthroat – nothing massive but plenty in the 14-18 inch range, with the occasional bruising brown reported by locals tossing bigger streamers. Ashby Bell landed a pristine valley rainbow and Sarah brought in a solid cutthroat, both on nymph-hopper rigs as shared by photos on Yellowstone Angler.
The hopper bite isn’t done yet, and local shops are still seeing success with peach and pink hoppers, sizes 8 to 14, especially when paired with a tungsten beaded nymph below. Floating ant patterns are quietly killing it, particularly above Yankee Jim or when things get extra glassy around Emigrant. For dries, Purple Bruces and Morrish or Grand Hoppers should stay in your box. They’re getting chased hard, especially with a beadhead prince or euro nymph dropper about 18 inches beneath.
On the nymph game, Black Rubber Legs, Duracell Bomb Browns, Blow Torch Blacks, and Little Spankers in the #12-18 range are working best, especially in faster edge water and seam runs. Streamer folks: the Sex Dungeon in black or olive, Coffee Sparkle Minnows, and Yellow Silk Kitty have turned a few notable browns and ‘bows midday on the deeper cuts. Mornings are for the patient – as the sun hits the water, be ready for the action to heat up fast.
The recent hatch has been all about lingering caddis and a sneaky Blue Winged Olive pop in the afternoons, so don’t leave those Elk Hair Caddis and Missing Link patterns at home. The Yellowstone’s browns are fired up by these overcast days, and streamer chasers are reporting more aggressive follows as we get later in the season.
Top baits have been tungsten bead nymphs, as well as small worms and eggs for those targeting the deep slots. The classic nightcrawler and PowerBait or spoons are putting up numbers for the spin crowd, especially near bridges and deeper holes.
The hot spots right now:
- Paradise Valley stretch between Carter’s Bridge and Emigrant, especially late morning once the sun warms things up.
- Above Yankee Jim Canyon – look for quieter water after the drop-offs, especially towards afternoon.
Keep in mind, it’s been getting busy out here with the last of the fall folks hunting those autumn trout, so mind your fellow anglers and give them space.
All in all, with hungry fish, jaw-dropping golden cottonwoods, and just enough chill in the air to make that thermos of coffee worth packing, it’s a picture-perfect autumn day on the Yellowstone. Thanks for tuning in – if this helped you out, don’t forget to subscribe to catch the next report.
