Autumn Angling on the Bighorn and Yellowstone

Welcome back, anglers. This is Artificial Lure, your local fishing and angling expert, with the latest hotline for the Big Horn area—October 11th, 2025. Let’s get right to the water. Sunrise today is at about 7:20, sunset right around 6:30. So you’ve got a little less than twelve hours of daylight—makes you want to get out early, especially with that chill in the air. Expect a mostly cloudy morning, maybe some sun by mid-afternoon—perfect for the fish, perfect for you. Water temps are cool, trout are showing their fall patterns, and that seasonal slowdown is just getting started. But hey, right now, it’s a great time to be on the water before the big push into late autumn. Tidal report? We’re not talking about tides here, folks—this is Montana, not the coast. We’re all about river flows, and right now the Yellowstone River, just a hop from Big Horn, is in prime shape. Water’s clear, flows are stable, and trout are feeding with abandon. Over on the Bighorn River, things are just as good—clear water, active fish, and plenty of room to pick your spot. In the last week, our guides and local chatter both say the Yellowstone has been hot. Bows, browns, and whitefish are all biting, and a good number of decent-sized trout are coming to the net—nothing record-breaking, but plenty to keep your rod bent. Down in Paradise Valley, streamer and nymph anglers are pulling in some real beauties, and even a few locals have turned up bigger browns than usual for this time of year. The go-to method right now is nymphing. Stonefly attractors and rubberlegs (the bigger, the better) as your lead fly, followed by smaller droppers like perdigons, princes, or zebra midges. Toss that rig into the deeper runs and along the seams, especially when the sun is high and the fish are hugging the bottom. If you want to swing flies, black and olive streamers on a 7-weight with a 250-grain sinking line are getting into fish in the deeper buckets and around structure—mornings and those cloudy days are prime time for aggression. Dry fly action? Not much yet—just a few BWOs and mayflies showing on calm, overcast afternoons, so keep some small parachutes or emergers in your box, but don’t pin your hopes on it. Bait’s another story. Live bait’s always good too—worms or grasshoppers work, especially early on. Try drifting a worm under a bobber in the slower water, or bouncing a little nightcrawler off the bottom. If you’re spin-casting, smaller spinners in gold or silver, or little crankbaits that mimic minnows, are a solid bet. Just remember, live bait means more local regulations—double-check your regs and keep things eco-friendly. As for hot spots? On the Bighorn, try the Afterbay area—always holds fish, and the water’s usually the right temperature. For the Yellowstone, you can’t lose between Livingston and Corwin Springs—both banks have great wade access, and the riffle-to-pool transitions are stacked up with trout.
