• Spring (March–May)

Spring is one of the most consistent and productive times on the Missouri. As water temperatures slowly rise, trout feed heavily on nymphs, scuds, and sow bugs, with afternoon Blue Winged Olive hatches providing excellent dry fly opportunities on cloudy days.

This is also one of the best times for streamer fishing and targeting larger brown trout.

• Summer (June–August)

Summer brings some of the most iconic dry fly fishing on the Missouri. PMDs, Caddis, and Trico hatches create steady surface action, while terrestrial fishing with hoppers, ants, and beetles becomes effective along the banks.

Early mornings and evenings are prime during the heat of summer, with technical nymphing and dry-dropper rigs producing all day.

• Fall (September–November)

Fall is a favorite among experienced anglers. Cooler temperatures bring aggressive feeding, hopper fishing, and excellent streamer opportunities for trophy brown trout as the spawn approaches. September and October are often considered some of the best months of the year on the Missouri.

• Winter (December–February)

Unlike many Montana rivers, the Missouri remains open and productive through the winter. Midges and small nymphs dominate, and trout feed steadily during midday hours. For anglers willing to brave the cold, winter offers solitude and surprisingly consistent fishing.

Consistent Tailwater Flows

The Missouri River below Holter Dam benefits from regulated releases from Holter Reservoir. This creates stable flows and cold, clear water throughout the year. Unlike freestone rivers that blow out during spring runoff, the Missouri often remains fishable when other Montana rivers are not—making it a reliable destination for guided trips.

High Trout Density & Trophy Potential

This stretch of the Missouri River is known for exceptional trout populations, with thousands of wild rainbow and brown trout per mile. Average fish range from 15 to 18 inches, with plenty of 20+ inch trout and true trophy brown trout available throughout the season. Craig Montana fly fishing is famous for both numbers and quality.

World-Class Insect Hatches

Missouri River fly fishing is driven by prolific insect hatches, including:

• Blue Winged Olives (BWO)

• Pale Morning Duns (PMD)

• Tricos

• Caddis

• Midges

These consistent hatches create incredible dry fly fishing, technical nymphing, and streamer opportunities.

Year-Round Fly Fishing Opportunities

Because of its tailwater nature, the Missouri River below Holter Dam fishes well all twelve months of the year. Winter midge fishing, spring Baetis hatches, summer dry flies, and fall streamer fishing make this one of the most versatile fisheries in Montana.

Craig — Small Town, Big Fishing Culture

The tiny town of Craig — sitting right on the river — exists because of the fly fishing that happens here. With only a handful of shops, restaurants, and bars clustered near the river, it’s a place where anglers share stories, compare hatch intel, and plan tomorrow’s strategy over dinner and a beer. Local fly shops like Crosscurrents, Headhunters, and Trout Montana are hubs for gear, flies that match the hatch, and the latest river reports.

Lodging Fills Up Fast — Here’s Why

Fly fishing here is hugely popular — so popular, in fact, that lodging books early. Options along the Missouri vary from classic cabins and vacation rentals to full-service lodges:

• Vacation Rentals & Cabins — vrbo-airbnb homes put anglers steps from the river or within a short drive.

• Additional Lodging — Places like Prewett Creek Inn and other rental homes between Craig and Cascade provide convenient staging points for float trips and access to great water.

Because the fishing season (especially June–August) draws anglers from across Montana and beyond, rooms and cabins sell out months in advance. If you’re planning a summer trip — particularly around peak hatches — book early and coordinate guides and lodging together if possible.
