If you’ve ever dreamed of targeting big trout in a stretch of river that lives up to its name, the Land of Giants below Hauser Dam should be on your radar.
This legendary stretch is a highly productive tailwater that flows through a breathtaking canyon before emptying into Holter Reservoir near the the Gates of the Mountains Wilderness. It’s home to some of the largest trout in the entire Missouri River system. As a result, the Land of Giants has earned a reputation as a world-class fly fishing destination for anglers in search of trophy trout.
Accessing the Land of the Giants Section
The most effective way to fish the Land of Giants is by jet boat, often called a power drifter. These nimble boats allow us to quickly and safely cross Upper Holter Lake and make our way toward Hauser Dam. Once we reach the river, guides switch to oars, rowing the boat like a traditional drift boat. This transition gives anglers a quiet, controlled approach perfect for targeting these large trout.
While the current in this section is moderate, the deeper runs, pockets, and riffles require mobility and precision. That’s where the jet boat really shines. Unlike a conventional drift boat, which often requires shuttles, a jet boat can motor up or down stream efficiently. This flexibility allows guides and anglers to access prime spots in a single day, maximizing fishing time.

Best Times to Fish the Land of the Giants
One of the best times to fly fish the Land of Giants is during the Pale Morning Dun , and Caddis hatches. These prolific hatches typically begin in late June and continue through August. During this period, the river comes alive with trout feeding on the surface, creating prime conditions for dry fly anglers. Pods of fish can be seen sipping in the slicks along the riverbanks all the way down to Holter Lake.

Land of the Giants Fishing Seasons
The Land of Giants offers incredible fishing opportunities from April through November. This unique stretch of the Missouri where lake and river meet, fishes differently than any other piece of water in Montana. Each season brings its own rhythm, shaped by trout behavior, water temperatures, and insect activity. Not to mention the bonus species like Northern Pike, Kokanee Salmon and Walleye.
Spring: kicks things off as the ice melts and the river wakes up. Rainbow trout begin their annual migration out of Holter Lake, pushing upriver to spawn below Hauser Dam. During this time, you’ll often find fish in classic tailouts and deeper runs, where nymphing can be exceptionally productive.
Summer, the spawn wraps up and trout slide back into feeding mode. They spread out between Holter Reservoir and the upper river system, following the buffet of emerging insects. Caddis, PMDs, and Callibaetis dominate the menu, and sight fishing opportunities increase.

Fall :The character of L.O.G. shifts once again. Cooler days and crisp mornings trigger trout to feed hard before winter sets in. This is a favorite season for many anglers, especially those who love to streamer fish. Big browns and rainbows turn aggressive, chasing down streamers. The colors of autumn, both in the landscape and the fish, make this time of year truly special.

Winter: Though quiet, still holds opportunity for those willing to brave the elements. Mild days can be magic swinging small streamers with a two handed spey rod or deep nymphing. The crowds are gone, the river is peaceful, and the solitude alone is worth the trip.

Wildlife and Geology
In addition to fly fishing, the Land of Giants area is also known for its abundant Montana wildlife. It’s not uncommon to see bald eagles, bighorn sheep,osprey, beavers, otters, and other wildlife along the river. The Land of Giants section of the Missouri River is a must visit destination for any flyfisher. With breathtaking scenery, crystal-clear waters, and massive trout, this stretch of river is truly a fly-fishing paradise.
