Rock Creek Fishing Report, May 5, 2026
Spring runoff is here. All four rivers are running high, off-color, and pushy with cold water in the mid-40s to low 50s. Subsurface fishing — bigger and darker — is the bread and butter, with dry-fly opportunities tied to afternoon hatches of March Browns, BWOs, late Skwalas, and the first Mother's Day Caddis on the Clark Fork and Bitterroot. The Bitterroot has officially entered peak runoff and is the toughest of the four; the Blackfoot and Rock Creek are the cleanest. Watch the gauges — forecast highs in the low 70s through Tuesday will push another snowmelt bump before Wednesday's cold front swings rain, snow, and 50s back through the system. Floaters: log jams and debris are still serious hazards, especially on the Bitterroot near Poker Joe.
Water: ~1,000+ cfs near Clinton, dropping · Visibility: 2–3 ft, improving · Temp: 45°F (low 40s away from town)
Rock Creek has come down and cleared from the recent cold spell. Pressure has noticeably picked up on the drive-in stretches, but tucking into less obvious water still feels like the Creek. Fish are holding in soft seams, inside bends, and slower buckets where they don't have to fight the current. Subsurface is still the bread and butter; dry-fly action is day-to-day, with the best shots in the warmer afternoons. Streamer fishing is excellent right now — baby trout and sculpin are scattered everywhere.
Hatches
Skwalas, March Browns, BWOs, Midges, plus the first caddis starting to flutter.
Best techniques:
- Heavy nymph rigs deep — Double Bead Stones, Pat's, or TJ Hookers paired with a smaller perdigon or worm dropper through deeper runs and pocket water.
- Skwala dry-dropper for prospecting; switch to a March Brown emerger or single dry when fish show up top.
- Streamers tight to structure — undercut banks, root wads, dark slots; flash works on bright days.

Outlook: Decent weekend with highs pushing into the 60s by Monday and Tuesday, but the warm daytime highs and rising overnight lows could push more snowmelt before Wednesday's cool-down and snow showers. Take advantage of the current window.
