If you’ve ever dreamed of targeting big trout in Montana, 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. If you’ve never fished from one, think of it as the best of both worlds: the quiet presentation of a drift boat combined with the power and flexibility of a motor.
These specialized boats feature a shallow-draft jet system that allows us to navigate both Upper Holter Lake and the flowing river sections efficiently. We begin each trip by quickly crossing the lake to reach Hauser Dam, maximizing your time on the water rather than traveling.
Once we reach prime fishing water, your guide switches from motor to oars, rowing the boat just like a traditional drift boat. This gives you the stealthy, controlled approach essential for targeting trophy trout while maintaining positioning for perfect presentations.
What sets the jet boat apart is its versatility. Unlike a conventional drift boat that requires a shuttle and limits you to a one-way float, a jet boat can move upstream or downstream throughout the day. If we find actively feeding fish, we can work that area thoroughly. If conditions change, we can quickly relocate. This flexibility allows us to adapt to the fishing and maximize your opportunities to connect with trophy trout this section is known for.
The Land of Giants’ moderate current, deeper runs, and complex structure make the jet boat not just advantageous, but essential. Its shallow draft allows access to water other boats can’t reach.

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 trophy trout 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. This movement concentrates fish and creates some of the most consistent fishing of the year. During this time, you’ll often find fish in classic tailouts and deeper runs, where nymphing can be exceptionally productive.
Summer: As summer settles in and the spawn wraps up, trout slide back into a steady feeding mode. Fish spread out between Holter Reservoir and the upper river system, no longer locked into spawning water and instead following the seasonal buffet of emerging insects. Caddis, Pale Morning Duns, and Callibaetis dominate the menu, offering more surface activity and longer feeding windows. With fish positioned in softer seams, flats, and along weed edges, sight-fishing opportunities increase.
Fall :The character of L.O.G. shifts once again as cooler days and crisp mornings settle in. These changes trigger trout to feed with urgency, packing on calories before winter takes hold. For many anglers, this is a favorite time of year, especially for those who love swinging or stripping streamers. Big browns and rainbows grow noticeably more aggressive, willing to chase down well-presented flies with conviction. Add in the rich autumn colors along the riverbanks and the deepening hues of the fish themselves, and it’s hard to argue there’s a more visually striking or exciting season on the water.
Winter: Though quiet, this season still holds real opportunity for those willing to brave the elements. On mild days, the fishing can be downright magical. Swinging small streamers with a two-handed spey rod or probing the deeper runs with nymphs. With the crowds long gone, the river settles into a slower rhythm. There’s a sense of peace out there, and often the solitude alone is reason enough to make 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.
