6/16/2026: Clark Fork River Fishing Report
Summary
Western Montana has shifted from runoff survival into real early-summer fishing. Flows are dropping across the region, clarity is improving by the day, and the Salmonfly hatch is the headline story, joined now by Golden Stones building everywhere, plus Green Drakes, PMDs, Yellow Sallies, and caddis filling in the dry-fly windows. Big-bug dry-dropper fishing is the dominant game on all four rivers. Rock Creek and the Blackfoot are the standout dry-fly options; the Bitterroot is the safest all-around bet; the Clark Fork is improving and rewards careful water selection. Warm afternoons are in the forecast, so fish the late-morning-through-early-afternoon window and watch water temperatures.
At a glance: Dropping, slightly off color, ~56°F midday. Upper ~4,490 CFS above Missoula, ~8,310 CFS below | GH 3/5 | Missoulian Angler 4/5
The Clark Fork has turned the corner from the recent flow bump and is starting to take shape, with the upper end clearing up nicely. There is still plenty of water moving, but the river is becoming more manageable and fish are spreading into typical early-summer lies. Golden Stones, PMDs, Green Drakes, and lots of caddis are hatching consistently, with Salmonflies still in the mix. Trout are looking up along grassy banks, inside bends, soft seams, foam lines, and side channels.
Best techniques
With the water still slightly off color, a nymph rig is the most consistent option: stonefly patterns like Pat's RLs, Explosion Stones, TJ Hookers, and Zirdles, plus Blowtorches, Shuck Its, Frenchies, Jig PTs, and Prince nymphs. Dry-dropper has been productive up top with Chernobyls, Golden Plan Bs, Dancin Rickys, and Blackout Stones in #8-12; look smaller with Ms. Tickle, Brindlechutes, and the Hi-Vis Micro Chubby when fish key on PMDs. Watch for Goldenstones on the lower river: a Golden Plan B, golden Juicy Stone, or Henry's Fork Goldenstone. Strip or swing Sparkle Minnows, Kreelex Minnows, and Woolly Buggers through slower water and structure.
Hatches
Golden Stones, PMDs, Green Drakes, caddis, and Salmonflies.

Outlook. Warmer temperatures into the 80s next week with a mix of sun and clouds will help bug activity build; midweek showers or thunderstorms could even improve the dry-fly bite. June and July on the Clark Fork are special and often overlooked. If flows keep dropping and clarity holds, expect steadily improving fishing with excellent dry-fly windows whenever a hatch peaks.
