The Missouri River between Holter Dam and Craig, Montana, has a reputation that precedes itself — and for good reason. It’s a tailwater fishery that produces rainbow and brown trout in numbers most anglers only dream about, running cold and clear year-round thanks to releases from Holter Dam. When Arizona-based YouTube channel Desert Fly Duo Productions made the trip up to fish it for three straight days this August, they were chasing exactly what thousands of out-of-state anglers chase every season: a legitimate shot at world-class trout on one of the most storied stretches of public water in the American West.
What makes the “Mo” special — and what visitors often underestimate — is how technical the fishing can get. Yes, the trout density is extraordinary, but these fish see pressure every single day of the season. August in particular brings heavy recreational boat traffic and educated fish that have been looking at dry flies since April. The prolific PMD and Trico hatches that define the Missouri’s summer calendar are tapering off by mid-August, giving way to hoppers and Pale Evening Duns. If you’re planning a trip, knowing what’s on the water matters as much as knowing how to cast. Montana Fish, Wildlife & Parks keeps the stretch from Holter to Cascade open to fishing year-round, but it’s worth checking current regulations — the Missouri has specific gear restrictions in certain sections that catch out-of-staters off guard.
There’s also something worth noting about the perspective Desert Fly Duo brings here. They fish desert Southwest rivers — the Salt, the Verde — where trout water is scarce and every outing is hard-won. Watching anglers with that background land on the Missouri for the first time gives you a fresh appreciation for what Montanans sometimes take for granted. The access is remarkable. The fishing is remarkable. The fact that you can float 30 miles of productive trout water on publicly accessible river without a single private-water fee is not the norm in this country, and it’s something Montana anglers should actively support and protect.
If you’ve been on the fence about making a run to Craig before the season turns, this video might be the nudge you need. September brings cooler temps, lighter crowds, and the beginning of the streamer bite that turns big browns aggressive ahead of fall. The Missouri River in early fall is about as good as Montana fly fishing gets — and that’s saying something.
