Winter has officially taken the wheel on the Madison, according to Madison River Fishing Reports as of November 11, 2026, and the river is behaving like three different rivers wearing one name. Up top, the park season closed October 31, but the year-round water from the state line to the West Entrance never shut its doors — it’s sitting at 303 cfs and roughly 50.7°F, suspiciously mild for mid-November because the Firehole keeps feeding it warm water, and Barns Pools and Cable Car Run are holding late fall-run fish with barely a soul around. The Upper is in full early-winter posture: steady at 727 cfs and 49.1°F, the fifty-mile riffle settling into its cold-season rhythm while run fish stack up between the lakes. The Lower has gone the furthest — 1,170 cfs and 43°F at McAllister, summer weeds dead and gone, with Bear Trap Canyon offering the best nymphing and the least company on the entire system.
The strategy this week is simple: sleep in, wade, and fish slow. Give the Upper the 10:30-to-3:30 slot and the Lower a tighter 11-to-3, work the deep, unhurried water, and leave the boat trailer at home — wading will out-fish floating until things change. Flies are a winter lineup now: Pat’s Rubberlegs (#6-8) doing the heavy lifting below, a Zebra Midge (#18-20) for tailwater fish that won’t move, and a Parachute Adams (#14-20) for any fall BWO trickle. The Chubby Chernobyls and Morrish Hopper can stay in the box until June — nobody’s looking. Reports refresh every 12 hours off three USGS gauges (West Yellowstone 06037500, Kirby 06038800, McAllister 06041000) blended with local weather and historical hatch timing, and that matters, because a single cold front or dam release can rewrite the whole plan overnight. Check the numbers the morning you go, not the night before!
