Bighorn River's Autumn Allure: Steady Flows, Eager Trout, and Layered Fishing

This is Artificial Lure with your November 3rd fishing report for Big Horn, Montana. It’s a bluebird morning out here – sunrise hit at 7:58 AM and we’ll lose that last cast around 6:07 PM. Daylight’s short and the cool weather’s here to stay, but if you layered up and made it to the river, you’re in for a treat. According to Montana Outdoor, fall fishing on the Bighorn River is in prime shape: steady flows, crystal clear water, and trout that flat-out refuse to let go of that autumn appetite. Weather’s classic Big Horn November: low 40s at dawn, topping out near 56 degrees by late afternoon, wind out of the west around 10-15 mph, and a slight chance of light rain mid-morning, but nothing that should send you home early. The barometer’s steady – fish are on a reliable bite, especially late morning through the afternoon. No tidal swings to worry about here, just steady river flow – perfect for presenting those flies slow and deep. Fish activity’s been hot since Halloween. The nymph bite is king with blue-winged olive (BWO) patterns producing steady action. Rig up scuds (orange and tan) or a sowbug dropper below a small indicator – fish are holding deep and slow, especially in those classic Big Horn runs and tailouts. Rainbow and brown trout are both active – most fish coming to hand have been solid 14-18 inchers, with a few pushing past 20 inches for lucky anglers working streamers or larger nymphs. Recent reports from locals say streamer junkies are scoring well with olive sculpin patterns and small black leeches, especially when worked right along the slower banks and undercut edges in the afternoons. Surface activity is subtle but present. If you’re a dry-fly diehard, watch for BWO hatches mid-afternoon, particularly on overcast days. Trout are sipping but can be picky—size down to 18 or 20, and drift carefully through slower water. Best baits right now? Stick with nymphs—BWO nymphs, scuds, sowbugs, and the occasional midge if you see heavy hatch activity. If tossing hardware, small silver and gold spinners or spoons are pulling in some aggressive browns along the deeper runs. Folks after numbers should dead drift those nymphs, but if you want that one big grab, swing a smaller articulated streamer right along the ledges after noon. Hotspots for the week: - The Afterbay section below the Yellowtail Dam: fish are podded up and eager in the first few miles, especially where side channels rejoin the main flow. - Second spot: the “Wheat Field” runs downstream, just above the Bighorn access site—less pressure, more willing trout, especially behind midstream boulders and weed beds. Overall, the Bighorn’s giving up numbers and some real quality. If you’re heading out on foot, focus on slower seams and inside corners; drift boaters can cover all the right water, but low flows mean you’ll want to move slow and fish every shelf thoroughly.
