Clark Fork 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 and pushy, ~6,000–6,300 cfs above Missoula · Visibility: off-color, slowly improving · Temp: 42–46°F

The Clark Fork is the dirtiest of the four rivers right now. Clarity is fishable but not optimal, and the river is fishing best from late morning through afternoon — especially under cloud cover. Subsurface tactics still rule. Worth keeping a dry box handy for opportunistic risers in back eddies and softer seams.

Hatches: Skwalas, March Browns (with Fluttering Skwalas midday), BWOs, a few Gray Drakes, early Mother's Day Caddis, plus Nemoura and Capnia stoneflies.

Best techniques:

• Dry-dropper with a Chubby, Water Walker, or Dancin' Ricky up top and a TJ Hooker, Prince, or Jig PT underneath is the go-to rig.
• Heavier indicator nymph rigs in slower buckets and transition water — Zirdles, Frenchies, dark perdigons all producing.
• Streamer fishing is very effective in the off-color water — dark and high-contrast, worked slow and deep along structure.

Featured flies:

• Dries: Carlson's Purple Haze, Stranahan's Brindle Chute, On Point Para Wulff – BWO, CDC Midge Adult, Bucky's Klinkhammer-Zebra, Chubby Chernobyl, Hi-Vis Micro Chubby, True Skwala, Blackout Stone, Dancin' Ricky, D&D Cripple, Ms. Tickle, Hairwing Drake, Last Chance Cripple, Parachute Adams, BWO Comparadun.
• Nymphs: MFC Speckled Double Bead Stone, MFC Tungsten 20 Incher, Solitude TJ Hooker, Rio's Sili-Leg Stone, MFC Jig Wonky Worm, MFC Jake's Depth Charge Jig Worm, Frenchies, Princes, Jig PT, Duracells, San Juans.
• Streamers: MFC Chicago Overcoat, Coffey's Conehead Sparkle Minnow, Lil' Kim, Kreelex, Rio Thin Mint Bugger, black/purple/olive Dungeons, Gongas, Woolly Buggers, Sir Sticks-A-Lot, Masked Avenger.

Outlook: Saturday into Tuesday warming to a peak around 73°F under partly sunny skies, then a midweek system drops temps back into the 50s with rain and snow on Wednesday. Watch for another flow bump as warmer nights move snowpack.
