Missouri River

The Crown Jewel of Montana Fly Fishing

The Missouri River near Craig, Montana is a broad tailwater river and is considered by many to be a true Montana trout fly fishing mecca. The Mo, as the locals call her, is our home water and arguably the most consistent fishery in the Rocky Mountain West and productive wild trout fishery in the lower 48. This river is best described as a gigantic spring creek where the rainbow trout grow fast and strong, the brown trout become husky and cunning, and the backdrops are just as gorgeous as the fish.

River Description

Often called "The Mo," this tailwater is best known for its wide, flat flows and enormous trout populations. The river fishes like a giant spring creek—requiring technical skills, light tippet, and long leaders, but the rewards are immense. It’s one of the few rivers where dry fly purists and nymphing addicts can both thrive.

Fish Species

Rainbow Trout
Brown Trout
Mountain Whitefish

Trout average 17-19 inches, with many larger fish regularly caught. Rainbows here are famous for their power and fight.

Fishing Seasons & Techniques

While the Missouri fishes well year-round, the action ramps up in early spring and stays hot through fall.

Best Times of Day is Mornings and evenings are best for dry flies and summer hatches. Nymphing can produce fish all day long in any season.

Techniques:

Nymphing: Most consistent method; great for beginners and pros alike
Dry Fly: The real draw—sight-fishing to rising fish during major hatches
Streamer Fishing: Especially productive in spring and fall for large browns

Insect Hatches

The Missouri River will amaze you with its aquatic insect hatches, average fish size, and an overall population of big rainbow trout and brown trout. Arguably, the Missouri River has no equal when it comes to consistently sight fishing dry flies for rising trout. The Missouri River is an insect factory, pumping out hatch after hatch throughout the seasons.

Midges and Blue-winged Olives will hatch from late March through May. Caddis will arrive in early May, leave in June and then come back in July and usually stay through the fall. There is rarely a day on the Missouri where we can’t get any trout to eat a caddis, even into late October.

The Pale Morning duns arrive in June and this hatch usually corresponds with the end of run-off. Tricos will appear sometime in early-July to mid-August, and this hatch is stunning in the millions and millions of bugs it produces – every day.

The terrestrial is usually in full swing by July 15, with grasshoppers, ants, and beetles getting gobbled up by big-eyed trout up and down the river. The fall Blue- winged Olive and October Caddis hatches round out the season, and usually send us into winter with a last blast. It is a true insect smorgasbord.

Best Areas of the River to Fish

Dam to Craig, Upper River: The highest concentration of fish and anglers to match.
Dearborn to Prewet, Canyon Section: The most picturesque with lots of fish.
Prewet to Cascade, Lower River: Heavy rapids to start, then wide and calm. This is where serious anglers go to get away.

Recommended Gear & Flies

Rod: 5–6 weight with long leaders (9-12 feet) for technical dry fly work
