Bitterroot River Fishing Report: April 28, 2026
Western Montana is in classic late-April spring transition: high but generally fishable flows, water temps still cold (41–48F), and the dry-fly window opening up day-by-day on the Bitterroot, Clark Fork, and Rock Creek behind Skwalas, March Browns, and BWOs. The Blackfoot remains the coldest and pushiest of the four — nymphing and streamers are still the right call there. A warm-up early next week (highs into the 70s) is likely to bump flows again before a cold front and rain/snow Wednesday.
Conditions: High but fishable · Visibility 3–4 ft · Mid-day water temp ~48F · Flows: West Fork low, Darby ~1,700 cfs, Bell Crossing ~3,150, Near Missoula ~4,390 at 6.02 ft. Real push on the lower river — good from a boat, limited for wading.
Warning: HAZARDS — float cautiously. Lots of trees down again this year and a few places are dangerous (Grizzly Hackle). Log jams and debris from the early runoff remain a major hazard (Blackfoot River Outfitters). Posted warning at Poker Joe Fishing Access noting a river blockage between there and Florence FAS (46.593246, -114.058361): "Portage clear left. Please use caution." (Kingfisher) Scout from above when possible and be prepared to portage. Call your local shop for the latest before you put on.
The Bitterroot is the highest-rated of the four right now (Missoulian Angler 4/5). Bug life is picking up across the board, with solid BWO and midge activity throughout the day, consistent Nemoura and Skwala hatches on much of the river, and thick March Browns and Gray Drakes. Dry-fly opportunities are improving — best in the morning hours and again near sunset.
Best techniques
- Mornings subsurface: cold nights keep the bugs and fish quiet until midday. Stonefly nymphs paired with smaller mayfly droppers — Pat's Rubber Legs, Front St. Stone, Double Bead Stone, Jig PTs, Jig Princes, Spanish Bullet, Blow Torches. Riffles, buckets, slow inside-bends; nymph deep 4'–6'.
- Midday dries: Skwala patterns and various mayfly imitations. Best fish caught close to woody structure where nymphs can't reach.
- Streamers: big, dark, high-contrast — work structure and deeper buckets.
Hatches: Skwalas, BWOs, March Browns, Nemouras, Gray Drakes, Midges.

Outlook: Continued warm sunny stretch through the weekend, low-70s by Tuesday. Wednesday brings a sharp drop into the 50s with rain and snow. Forecast highs next week could rise flows enough to affect dry-fly fishing — get out and enjoy this dry-fly window while you can.
