Clark Fork River Fishing Report, July 14, 2026

2026-07-14 (July 14, 2026)

Regional summary

Conditions have held their line since last week, but the calendar has quietly turned a corner. The rivers kept dropping and clearing right through the weekend, and the real change is in the bug board: the big stoneflies that carried June are packing up, and the fish are settling into a smaller, steadier summer diet of PMDs, Yellow Sallies, caddis, and the first terrestrials. Salmonflies are gone and Golden Stones are on their way out, still worth a big searching dry but no longer the main event. Every gauge in the valley now reads lower than it did a week ago, so trout are tucked into defined summer lies, seams, riffle edges, shaded banks, and soft inside water, rather than pinned to the flooded margins. The one thing that runs the whole show this week is heat. Morning water is still cool and friendly, but afternoons are climbing into the upper 80s and 90s, so the productive window has slid firmly toward early and late. Carry a thermometer, start at first light, handle fish fast in the warm afternoons, and check Montana FWP for restrictions before every trip, since nothing was posted when the shops filed but a hot stretch can change that overnight.

At a glance: Dropped into great summer shape, best clarity through and west of town | slightly off color, improving | 64°F morning | ~2,670 CFS above Missoula, ~4,510 below (live USGS, down from ~4,150/7,840 a week ago) | GH rating: 3/5 (7/10) | Best window: early and late

Float hazard: new tree down between Turah and Sha-Ron. about half a mile above the Clark Fork and Blackfoot confluence. The report is recent and details are thin, so call Blackfoot River Outfitters (406.542.7411) before floating that stretch.

The Clark Fork has cleaned out fast after last week's rain and dropped into genuinely good summer shape, with clarity much improved and the fishing running consistent. The upper river above town is going low and weedy, but the water through Missoula and west of town has been the strongest hand in the valley, an overlooked river this time of year that quietly rewards anglers who work it. Fish are stacked in the soft, defined water: grassy banks, inside bends, foam lines, side channels, drop-offs, and the seams beside the heavier current. First thing in the morning, look tight to the banks for nocturnal stones before the sun gets on the water.

Best techniques

• Search the soft edges with a dry-dropper. Put a high-floating golden up top, a Chubby Chernobyl, Water Walker, Clark Fork Stone, Supa-Dupa Stone, or Fools Gold in #8-12 tan, gold, or purple, and run a Jigged Hare's Ear, Perdigon, Psycho May, or PMD nymph three to five feet below.
• Nymphing is the reliable midday play while the last 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. Focus the eddies, riffles, and buckets.
• The dry day runs on a clock: PMDs and goldens midday, sallies and drakes behind them, then caddis and PMD spinners in the evening (Elk Hair Caddis, X-Caddis, Corn Fed Caddis, Sparkle Duns). Do not overlook streamers here; the CF has been fishing yellow, white, and olive well, with the Rusty Trombone, Kreelex, Lil' Kim, and Barely Legal worth a pass along shaded banks. Grizzly Hackle keeps the deepest cripple and spinner bins in town if the evening fish turn 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.

The Fly Box

Nymphs: Pat's Rubber Legs, Explosion Stones, Twenty Inchers, TJ Hookers, Zirdles, Blowtorches, Frenchies, Jig PTs, Prince Nymphs, Split Case PMDs, Psycho May, Jigged Hare's Ear, Perdigons

Outlook. Warm and a little unstable, with a brief shower chance early in the week, a cooler Tuesday, then more afternoon storm potential Thursday and Friday. If the drop holds, this is the week to hunt the Clark Fork's soft water while everyone else chases the prettier rivers; June and July are quietly its best act.
