Clark Fork River Fishing Report: May 10, 2026
Snowmelt v3 has the entire Missoula-area system high and off-color. Nymphing and streamers are the play across all four rivers; dry fly action is limited but improving on the Bitterroot, where fish are starting to look up in the evenings. Stay safe wading or floating — log jams and tree hazards remain a real concern, especially on the Bitterroot.
Conditions at-a-glance: Flows up to 6,400 cfs near Missoula · Water condition: high, muddy, off-color · Mid-day water temp: 51°F · Visibility: poor.
Poor visibility. Recent runoff push has dropped clarity sharply. Stick to the slowest holding water you can find and fish flies that move water and grab attention.
Hatches are continuing to build despite the dirty water — March Browns, BWOs, Mothers Day Caddis, and the start of the fluttering stone hatch are all in the mix, with Grey Drakes and fluttering Skwalas on top of that. Look for risers in soft eddies and back seams during the warmest hours and the last hour of light.
Best techniques
- Nymph the slow inside seams, drop-offs, and back eddies with heavy stonefly + mayfly tandem rigs.
- Dry-dropper rigs are best in size 10–12 once midday hatches start popping.
- Streamers in dark colors (black, purple, olive) — fish them slow and deep along structure; mix in white or gold flashy patterns where you find a window of cleaner water in side channels.

Outlook: Highs from 71°F today peaking near 84°F Wednesday with mostly sunny to partly cloudy skies; a 35% chance of light rain mid-week. Expect another flow bump as the warm-up accelerates melt; the Clark Fork's recovery to fishability will follow flow stabilization.
