Blackfoot River Fishing Report, July 30, 2026

2026-07-30 (July 30, 2026)

Regional summary

On July 29 the restrictions caught up with the whole valley. FWP's new orders put the Blackfoot on hoot owl from Cedar Meadow down to the Clark Fork confluence, stretched the Clark Fork's hoot owl to the entire river (from its birth at Warm Springs and Silver Bow creeks all the way to the Flathead confluence), and added Upper Rock Creek from the forks down to Stoney Creek. Monture Creek and Upper Lolo Creek joined the list the same day, and three Clark Fork tributary mouths (Fish Creek, Rattlesnake Creek, and the St. Regis) are now closed to all fishing within 100 yards, because bull trout and their neighbors are stacked in those cold seams for thermal refuge. Leave them alone. The Bitterroot, restricted since July 22, is no longer the exception; it is the template. Add wildfire smoke hanging over the valley, highs in the 90s all week, and another step down in flows, and the shape of the fishing is not in dispute: this is a dawn fishery now, everywhere, with a 2:00 p.m. legal curfew on most of it. The good news is that the mornings are excellent. Tricos and PMD spinners own the glass at first light, spruce moths are producing real fish mid-morning on the timbered water, hoppers, ants, and beetles headline everywhere, and the trout, packed into the oxygen, are easy to find if you are willing to set an alarm.

At a glance: ~987–1,020 CFS at Bonner and stepping down | 70°F midday | clear, dropping, full summer character | GH rating: 3/5 | Best window: 6:00–10:30 a.m. | Now on hoot owl from Cedar Meadow FAS to the Clark Fork confluence (no fishing 2 p.m. to midnight) | Floating still closed Weigh Station to I-90 through October 31

Float hazard: North Fork obstruction below Harry Morgan. The blockage that has already wrecked several boats is still there. Walk your boat around it or launch at River Junction. Storms moved through this week, so assume new wood anywhere on the river until you have seen the line yourself.

The river that dodged restrictions last week did not dodge them this week. The lower Blackfoot's 2:00 p.m. cutoff formalizes what the thermometer had already decided, since the water is touching 70 by midday anyway. Under the new rules the playbook barely changes: the Blackfoot at 987 CFS is a morning terrestrial river, technical but generous. The fish live where the water works for a living, in plunge pools, boulder gardens, and the quick inside seams under grassy banks where the current serves breakfast. Bonus development worth planning around: the spruce moth bite Grizzly Hackle called epic-in-the-making is arriving on schedule, with fish eating moth patterns from mid-morning.

Best techniques

• Search the banks with foam and a trailer: #8-12 Chubby Chernobyl, Sweetgrass Hopper, Henneberry Hopper, Juicy Hopper, or Water Walker up top, with a Prince Nymph, Jigged Hare's Ear, Duracell, Frenchie, Shuck It, or Jig PT two to three feet down. Start the dropper deep and shorten as the morning warms.
• Give the moths their shift: Billy's Butterfly, Potter's Fat Head, and the Snowshoe Moth from mid-morning, then rotate to the small stuff for picky fish, CFO Ants, Glitter Ants, Heifer Hoppers, Morrish Hoppers, and Plan Bs against the cutbanks.
• First light belongs to the little dries: PMD spinners and Tricos on the slicks and tailouts, a single ant or beetle in the foam, Elk Hair Caddis or X-Caddis for early risers.
• If the foam gets refused, go small and flashy underneath the surface: Sir Sticks-A-Lot, Space Invader, Sparkle Minnow, or Goldie through the deep plunge pools. The shops handling this river daily have the freshest word on where the new wood landed, and a five-minute stop for flies doubles as a float briefing.

Hatches

Terrestrials run the show: hoppers, ants, and beetles along every grassy edge, with spruce moths building in the timber. Late PMD spinners and Tricos work the morning glass, Yellow Sallies and caddis linger, nocturnal stones produce early, and the last of the drakes are a memory more than a hatch.

Outlook. 90s and sun near Ovando through the weekend and into next week, with smoke in the air. Expect the hoot owl boundary to hold or grow, the spruce moth fishing to keep improving, and the morning window to stay the whole game. When the water cools even a few degrees overnight, the first two hours repay the alarm clock.
