Missouri River Fishing Report, July 7, 2026

2026-07-07 (July 7, 2026)

Summary

Nothing has moved since this morning, and that stillness is the story. No shop has posted since Headhunters Fly Shop's Sunday update out of Craig, flows have barely wiggled (3,550 cfs and 62.6°F below Holter as of 2:45 this afternoon, against 3,390 flat in Sunday's report), and the tailwater is running to a fixed timetable this week, arriving at each stop on schedule. Stability on a tailwater is not boring; it is the whole appeal. When a river keeps its own timetable, an angler can plan a day around it and trust the connections.

Reach: Holter Dam to Cascade, Land of the Giants below Flow: 3,550 cfs below Holter (USGS, 2:45 p.m. today); Headhunters called it flat at 3,390 on Sunday, so call it steady and low for the date Water temp: 62 to 63°F, cool nights holding the mornings in the safe zone Clarity: Clear, with weed growth building toward the midsummer bloom Traffic: Holiday guests draining home; weekdays pleasant, weekend afternoons still busy with the recreation crowd

The river is busy with feeding fish and the anglers exercising them, and the fish have earned their mid-season PhDs. Long leaders, accurate casts, and fly-first presentations separate the catching from the casting right now. Low flows for the date make wading easy and keep fish podded up in predictable water, which cuts both ways: easy to find, hard to fool.

Best techniques

The Missouri right now runs less on where than on when, and the timetable has not changed in a week.

Early morning is the worm and sow station. A Wire Worm or Zirdle (that connection has about run its course; fish it fast and shallow if you fish it at all) paired with a Tailwater Sowbug covers the pre-hatch shift over gravel.

Mid-morning the Tricos pull in, columns of them up and down the river. Clusters and spinners are the transfer: a Buzzball on the cluster days, a CDC Para Spinner or Profile Spinner when they spread out, with reach casts and slack line doing more of the work than fly choice. When the small stuff starts popping around 10 or 11, downsize the nymph rig to match: Micro May, Split Case PMD, Brown Perdigons, Frenchie.

Midday holds at nymph-and-swing. Short rigs are the shops' consensus: 2 to 4 feet to a caddis pupa trailed by a PMD-brown nymph per Headhunters Fly Shop, or Cross Currents Fly Shop's version, roughly 5 feet to the first fly over 4-to-6-foot gravel, short-leashed to 2 or 3 feet on the flats, banks, and through the pods. Whitefish tax applies. When fish swirl just under the surface without showing noses, swing a soft hackle through them (Partridge and Yellow, PMD Soft Hackle, Loop Wing Emerger, Captive Dun) and hold on.

Evening arrives on schedule with the caddis show, and it keeps improving. The best emergences have been up top around Holter and the Wolf Creek Bridge. Start with the CDC stable (Flambé, Double Duck, Corn Fed, Henry's Fork Caddis) and the Translucent Emerger and Translucent Pupa behind them; as the hatch wears on and the fish wise up, go smaller and lower-profile than feels reasonable (Sam's Hi-Vis Spent Caddis earned its keep in the last big blow-up). Skittering an adult through skinny water is the fun version. Last light can still put a few big heads up on brown drakes: Hi-Vis Brown Drake or the CDC Para Spinner in drake sizes.

Between all of it, blind-fish a visible mayfly or hang a dry-dropper in the skinny water: a Chubby over a Micro May or Frenchie remains the two-fly answer, and every so often a big brown eats the Chubby instead. Streamers stay an early-and-late proposition while the sun is off the water: small and dark first (Thin Mint, Peacock and Black Bugger, Mini Sculpin), flash second (Kreelex, Sparkle Minnow, Bam Bam), and a big white Dungeon if your heart can take it. Get the meat out while you can; the weeds are coming.

Hatches

Tricos every morning and thickening, caddis every evening and improving, PMDs grinding to a halt, ants and terrestrials worth carrying, and the sneaky sideshow of Yellow Sallies and nocturnal stones for anglers willing to fish dark bugs at odd hours. The Craig shops see a thousand drifts a day this time of year; ten minutes at either counter, Headhunters Fly Shop or The Trout Shop, will calibrate your caddis sizes better than any report, this one included.

Outlook. More of the same, which is the good news. Sun and 70s-to-low-80s ahead, cool nights protecting the morning water temperatures, Tricos building, caddis improving, and the PMD chapter closing for the season. The weed bloom is the one connection working against the schedule; the streamer and deep-nymph water gets harder to fish every week from here. Weekdays are the play while the holiday traffic drains out. Same river as this morning, in other words, and it is a good one.
