Clark Fork River Fishing Report, July 9, 2026
2026-07-09 (July 9, 2026)
Regional summary
Not much has changed since the start of the week, and that is exactly the news you want to hear. The holiday rain bump has kept receding on schedule, every river is a notch clearer than it was two days ago, and the fish are still parked in comfortable summer water eating a deep, varied menu. Think of it as a slow tide going out: the extra volume that came with the storm is draining off a little each day, leaving trout spread through the seams and edges instead of pinned to the banks. The bug board is full summer variety, with Golden Stones anchoring the top and PMDs, Green Drakes, Yellow Sallies, and caddis rotating through the day, plus the first terrestrials and nocturnal stones nosing in. Salmonflies are behind us now. The one variable worth planning around is heat: after a slight shower chance today, the forecast marches into the upper 80s and low 90s, so the productive window keeps sliding toward morning. Fish early, carry a thermometer, and check FWP for restrictions before you launch, since nothing was posted when the shops filed but a hot Friday can change that.
At a glance: Elevated but dropping and improving, best clarity through and west of town | variable by section | 61°F midday | ~4,150 CFS above Missoula, ~7,840 below | GH rating: 3/5 (7/4) | Best window: 7:30 a.m. to 1:30 p.m.
Float hazard: tree down between Turah and Sha-Ron, about half a mile above the Clark Fork and Blackfoot confluence. The report is recent and the details are thin, so call Blackfoot River Outfitters (406.542.7411) before floating that stretch.
The Clark Fork wore the rain the hardest of the group and is a step behind its neighbors on the recovery clock, but the trend line is pointed the right way. Volume is still up and clarity still swings between sections, so give the muscular middle of the river a pass and hunt the margins where fish have settled: grassy banks, inside bends, foam lines, side channels, drop-offs, and the soft seams next to fast water. The upper river is going low and weedy, while the water through Missoula and west of town has been the strongest hand. First thing, look along the banks for nocturnal stones, which are starting to matter here before the sun gets on the water.
Best techniques
- Work the soft edges with a dry-dropper. Put a high-floating golden up top, a Chubby Chernobyl, Water Walker, Clark Fork Stone, Fools Gold, or Supa-Dupa Stone, with a Jigged Hare's Ear, Perdigon, or Psycho May running three to four feet under.
- Nymphing is the reliable play while color clears: lead with the stonefly crowd (Pat's RLs, Explosion Stones, Twenty Inchers, TJ Hookers, Zirdles) and follow with Blowtorches, Frenchies, Jig PTs, and Prince nymphs as the day matures.
- The dry day runs on a clock: PMDs and goldens midday, sallies and drakes behind them, caddis and PMD spinners in the evening (Elk Hair Caddis, X-Caddis, Corn Fed Caddis). And do not overlook streamers; tinted water is exactly when yellow, white, and olive shine, with the Kreelex, Barely Legal, and small sculpins worth a pass along shaded banks. Grizzly Hackle has the deepest cripple and spinner bins in town if the evening fish get technical.
Hatches
Golden Stones steady with nocturnal stones creeping in early, consistent PMDs, Green Drakes on gray days, Yellow Sallies, and loads of caddis with evening spinner falls.

Outlook. A storm chance today, then warm and increasingly hot into the weekend. If the drop holds, this is the week to hunt soft water while everyone else chases the prettier rivers; June and July are quietly the Clark Fork's best act.
