Western Montana is officially in its late-fall fishing program, but this week’s unusually mild weather should make for comfortable fishing, according to Lightweight Fly Shop in Stevensville, MT. Flows have settled and cleared across the region — the middle Bitterroot sits around 425 CFS near Victor, the lower Bitterroot at 849 CFS, the Blackfoot near 627 CFS, Rock Creek around 270 CFS, and the Clark Fork at roughly 1,555–2,399 CFS. Trout are concentrating in deeper, slower winter holding water, with Blue-Winged Olives and midges the main surface insects. The report’s overall strategy is simple: “Sleep in, fish the deeper winter water, and let the river tell you when to switch to dries.” The best fishing window runs roughly 11:30 a.m. to 4:00 p.m., and no emergency restrictions are in effect — though Rock Creek remains closed to fishing from boats through November 30, and anglers are reminded to give spawning redds plenty of room.
Each river has its own program this week. The middle and lower Bitterroot are the report’s “best overall local choice,” combining forgiving winter holding water with afternoon BWO chances, steady nymphing, and streamer fishing. The Blackfoot is the “best dedicated streamer option” — deep buckets and slow boulder seams are the program, and the report advises anglers to “concentrate on productive buckets rather than covering every bank.” The Clark Fork is the pick for big-water anglers hunting short afternoon dry-fly windows, Rock Creek is the best wade-fishing alternative, and the tiny West Fork Bitterroot (57 CFS) is highly technical water best left to experienced anglers. On hatches, the report is blunt: “BWOs and midges now own most of the dry-fly box. The days of building a November fishing plan around October Caddis are essentially over.”
The daily forecast favors cloud cover for dry-fly work and warmth for subsurface fishing: Sunday and Monday are cloudy with highs in the low 50s — the better BWO setups — while Wednesday through Friday warm into the upper 50s and low 60s, stretching the nymphing and streamer windows even if brighter skies make rising fish more selective. Gear picks lean practical: a warm layering system, 5X–6X tippet for selective surface feeders in clear water, and weighted nymph and streamer setups to reach trout sitting near the bottom. As for whether November is still worth the effort, the report says yes — fewer anglers, shorter feeding windows, and more subsurface fishing, but “mild November days can produce excellent fishing if you concentrate on the right water during the right part of the day.”
