Blackfoot River Fishing Report: May 3, 2026

The Missoula-area rivers are easing into late spring. Flows have been dropping and clearing this week thanks to a stretch of cooler weather, and the dry-fly window keeps widening — March Browns, BWOs, and Gray Drakes are the headliners, with Skwalas still in the mix on the Bitterroot River and Rock Creek and the first Mother's Day Caddis starting to pop on the lower Clark Fork River. Subsurface still pays the bills, but a real dry-fly bite is showing up midday and into the evening — especially on the Bitterroot River, which is the standout river right now. Watch the gauges early next week: forecast highs into the low 70s could push another snowmelt bump before Wednesday's cold front swings temperatures and precipitation back through the system.

Water: High but trending right, ~3,000–4,000 cfs at Bonner · Visibility: 2–3 ft, improving · Temp: 43–45°F

The Blackfoot is moving in the right direction. Flows have eased through the week and clarity is improving daily — best in the upper and mid sections. Cold water is still keeping the surface bite limited, but nymphing and streamers are paying off. Expect another bump if next week's warm-up melts more snow.

Hatches: Midges, BWOs, March Browns, Gray Drakes, straggler Skwalas, plus Nemoura and Capnia stoneflies on warmer afternoons.

Best techniques:

• Nymphing is the most consistent — heavy stonefly setups with a mayfly or worm dropper, fished deep (4–6 ft) on inside seams, slow drop-offs, and back eddies.
• Streamer fishing has been productive in the off-color water — bigger and darker now, lighter (white, gold) as clarity improves.
• Limited dry action; keep March Brown and BWO patterns ready for warmer afternoons. Drop a small mayfly emerger like a Jig PT, Duracell, or On-Point Mayfly off a foam dry to target the post-lunch March Brown hatch.

Featured flies:

• Dries: Galloup's Goober Midge, Griffith's Gnat, Bucky's Klinkhammer-Zebra, Carlson's Olive Haze, On Point Para Wulff – BWO, Chubby Chernobyl, Ms. Tickle, D&D Cripple, DL Cripple, Hairwing Drake.
• Nymphs: Rubberlegs, Solitude TJ Hooker, Double Bead Stones, MFC Trina's Squirm, Hot Bead Power Worm, San Juans, Tungsten Jig Pheasant Tail, Jig PT, Duracells, Hares Ears, On-Point Mayfly.
• Streamers: MFC Chicago Overcoat, Coffey's Conehead Sparkle Minnow, Kreelex, Lil' Kim, MFC Beadhead Woolly Bugger, Dungeon, Shake & Bake, Slick Willy, Sculpzilla Streamer.

Outlook: Highs climbing from the mid-50s Saturday into the 70s by Tuesday near Ovando, then a midweek cold front with rain, snow, and 50s on Wednesday. Watch the gauge — the warm-up could trigger another snowmelt push.
