Clark Fork River Fishing Report, July 3, 2026
2026-07-03 (July 3, 2026)
Regional summary
Western Montana comes into the July 4th weekend on the back side of a cool, wet stretch. This week's rain bumped every river in the region (hardest on Rock Creek, gentlest on the Blackfoot), pushed the Clark Fork above its historical median, and softened clarity in spots, but everything remains fishable and the water is settling daily. Golden Stones are the headline bug on all four rivers now, with salmonflies reduced to stragglers on the upper Blackfoot canyon and high drainage water. PMDs, Green Drakes, Yellow Sallies, and caddis round out the "bug soup," and dry-dropper remains the dominant method everywhere. The forecast flips warm: a chance of afternoon thunderstorms Friday, then mostly sunny holiday weather Saturday and Sunday. The two things to plan around are post-rain clarity (check gauges before committing) and holiday crowds (fish early, expect busy accesses, and have a backup stretch in mind). One rule change to note: Rock Creek converted to wade fishing only on July 1.
At a glance: Bumped and above the median for the date, fishing well | slightly off color, variable clarity | ~64°F midday (6/26 reading) | ~3,170 CFS above Missoula, ~6,690 below (6/28 readings) | GH rating: 4.5/5 | Best window: 10:00 a.m. to 4:00 p.m.
Float hazard: tree down between Turah and Sha-Ron. Details remain limited; call Blackfoot River Outfitters (406.542.7411) for the latest before floating that stretch.
The Clark Fork bumped with the rain and is carrying noticeably more water around Missoula, with flows above the historical median for the date. Expect stronger current, more push along the banks, and slightly variable clarity, but the river is still very fishable and has been one of the region's quiet stars: the water through and west of town has been stellar, while the upper river is getting low and weedy. Hunt the soft-water margins: grassy banks, inside bends, foam lines, side channels, drop-offs, gravel-bar shelves, and slower seams next to heavier current. Golden Stones remain the main focus (with some attention on nocturnal stones), joined by PMDs, Green Drakes, Yellow Sallies, and lots of caddis. The dry-fly fishing has been picking up around lunchtime and continuing through the evening.
Best techniques
- Dry-dropper a golden stone up top: high-floating patterns like the Chubby Chernobyl, Water Walker, Clark Fork Stone, Fool's Gold, and Supa-Dupa Stone in #8-12 (tan and gold have been the colors), with a Hare's Ear, Perdigon, or Frenchie underneath. Start the dropper 3 to 5 feet deep and adjust as bugs move.
- Subsurface, lead with stonefly nymphs (Pat's RL, Explosion Stone, Twenty Incher, TJ Hooker, Zirdle), then Blow Torch, Shuck It, Jig PT, and Prince as the day goes on. Nymphing is the most reliable option when wind, sun, or color make the dry-fly game tough.
- Risers run on a schedule: PMDs and goldens first, Yellow Sallies and drakes midday, caddis and PMD spinners in the evening (On Point Para Wulff, PMD Flash Cripple, Hi-Vis PMD Spinner). Streamer fishing has been stellar and often overlooked: yellow, white, and olive, with the Rusty Trombone, Kreelex, and Lil' Kim performing well.
Hatches
Golden Stones steady with nocturnal stones in the mix, consistent PMDs, Green Drakes on cloudy windows, Yellow Sallies, and heavy evening caddis plus PMD spinner falls.

Outlook. Warm and mostly good for the holiday stretch: a thundershower chance Friday, mostly sunny on July 4th. As the rain bump settles the Clark Fork should keep improving. Holiday crowds: heavy recreation pressure around popular floats, ramps, and town stretches; start early and give yourself extra time at accesses. Don't overlook this river in early July.
