Mid-June Fishing Report: Canyon Ferry, Hauser, and Holter Reservoirs
Fish on! The latest FWP report from Helena is in, and it’s looking like a “choose your own adventure” out on the water. From deep-dwelling kokanee to shore-side walleye, here is exactly where they’re biting and what they’re hitting on Canyon Ferry, Hauser, and Holter right now:
Canyon Ferry: Walleye fishing continues to be good at times between Pond 1 and Pond 3, around White Earth and north of White Earth along the west shore. Trolling bottom bouncers with worm harnesses has been the most productive with a few being caught on jigs. Rainbows are being caught on the north end and around White Earth while trolling crankbaits, spoons or cowbells. Rainbows and an occasional perch are being caught while fishing for walleye. Shore fishing has produced both rainbows and walleyes on worms or jigs with a worm around the Silos, Hellgate and Chinaman’s. The carp spawn is providing action for both bow fishing and hook and line. Troy Humphrey, FWP, Helena
Hauser: The walleye bite has been good inside the Causeway Arm, out from White Sandy and around Eldorado Bar while pitching jigs and crawlers or using slip bobbers and a leech. Fishing during the late evening has been productive for walleye. A few rainbow trout are being caught below Canyon Ferry Dam with worms or Power Bait, and while trolling flashers or crankbaits between Black Sandy and the Dam or near York Bridge. Chris Hurley, FWP, Helena
Holter: Walleye fishing has been good inside the Canyon, near Willow and Cottonwood Creek, and near the Clay Banks while jigging with crawlers or using slip bobbers and leeches. Fishing for walleye during the late evening hours has been productive. A few perch are being caught throughout the reservoir while searching for walleye. Good numbers of rainbow trout continue to be caught throughout the reservoir while trolling flashers and spinner combos around 15-20 feet deep. Fly fishing on the upper end of the reservoir with midge nymphs and using worm and marshmallows from shore at Departure Point and other public boat ramp areas has been producing a few trout as well. A few kokanee are being picked up near the Dam while trolling dodgers and hoochies or wedding rings tipped with corn at least 40 to 50 feet deep. Some kokanee anglers are doing well during the early morning hours. Chris Hurley, FWP, Helena
Why These Three Reservoirs Matter to Montana Anglers
Canyon Ferry, Hauser, and Holter form a chain of Missouri River reservoirs just east and north of Helena that collectively represent one of the most productive and accessible fisheries in the state. Fed by the same river system and managed in concert by Montana FWP, each reservoir has its own distinct character, depth profile, and fish community. Together, they offer something for nearly every style of angler — from the shore fisherman tossing worms at Canyon Ferry’s Silos to the kokanee troller running deep lines near Holter Dam.
Mid-June is a pivotal time on all three reservoirs. Water temperatures are climbing toward their summer range, post-spawn walleye are recovering and feeding aggressively, rainbow trout are active before the hottest weeks arrive, and species like kokanee are beginning to move deeper as the thermocline establishes. Knowing what’s happening on each body of water — and why — helps you make smart decisions about where to launch and what to rig.
Canyon Ferry Reservoir: Big Water, Big Opportunities
Canyon Ferry is the largest of the three, stretching roughly 25 miles long with a surface area that makes it feel almost like an inland sea on a windy afternoon. That size means anglers need to be strategic about location, and the current FWP report gives you a solid roadmap.
Walleye: Work the West Shore
The stretch between Pond 1 and Pond 3, and especially the White Earth area along the west shore, is where walleye action is concentrating right now. Bottom bouncers with worm harnesses are the go-to setup — a classic presentation that keeps your bait close to the bottom where walleye are hunting. The key with bottom bouncers on Canyon Ferry is boat speed: experiment between 1.0 and 1.8 mph until the fish tell you what they want. Jigs tipped with a half-crawler are a solid backup when the bite slows or wind makes controlled trolling difficult.
Shore anglers are finding walleye and rainbows around Silos, Hellgate, and Chinaman’s on worms or jigs tipped with worm. These areas offer decent structure and are accessible without a boat, making them excellent options for families or anglers who prefer to fish from land.
Rainbow Trout: Troll the North End
Trolling crankbaits, spoons, or cowbells around the north end and near White Earth is producing rainbows. Cowbell rigs — a string of spinner blades ahead of a baited hook — create flash and vibration that trout can’t resist, especially in slightly stained or choppy water. Vary your depth until you find the fish; canyon ferry rainbows often suspend, so don’t be afraid to run your gear shallower than you think necessary.
Bonus Action: The Carp Spawn
It’s worth highlighting the carp spawn separately because it offers a genuinely unique fishing experience. Bow fishing for carp during the spawn is exciting, fast-paced action — you’ll often see fish in extremely shallow water along weedy shorelines. Hook-and-line carp fishing with dough baits or corn can also be surprisingly fun and is a great way to keep kids engaged. Carp are underutilized by Montana anglers, but they fight hard and are plentiful right now.
Hauser Lake: The Hidden Gem Between Two Giants
Hauser sits between Canyon Ferry to the south and Holter to the north, and it sometimes gets overlooked — but the current report suggests that’s a mistake. At roughly 3,700 acres, Hauser is smaller and more intimate than its neighbors, which can actually make fish easier to locate.
Walleye: Evening Is Prime Time
The Causeway Arm, the area out from White Sandy, and Eldorado Bar are all producing walleye right now. The emphasis in the FWP report on late evening fishing is worth taking seriously. Walleye are notoriously light-sensitive and often feed most actively during low-light periods — dusk through dark can be the most productive window of the entire day, especially in clear-water conditions. Pitching jigs and crawlers along the edges of structure, or running slip bobbers with a leech over known walleye flats, are both effective approaches here.
Rainbow Trout: Below the Dam and Beyond
Below Canyon Ferry Dam — where the river enters Hauser — is a consistent trout producer, and right now worms and Power Bait are working for anglers fishing from the bank. Trollers are finding success running flashers or crankbaits between Black Sandy and the dam, and near York Bridge. These areas receive oxygenated, cooler water from the dam release, which concentrates trout, especially as surface temperatures begin to climb through summer.
Holter Reservoir: Depth, Variety, and Some of the Best Scenery in Montana
Holter may be the most scenic of the three, sitting at the northern end of the chain where the Missouri River cuts through dramatic canyon country before opening into the reservoir. It’s also arguably the most diverse fishery of the trio, with walleye, perch, rainbow trout, and kokanee salmon all in play right now.
Walleye: Canyon Structure and Creek Mouths
Inside the Canyon, near Willow and Cottonwood Creek, and along the Clay Banks — these are your walleye targets. Creek mouths are classic walleye magnets because they funnel baitfish and create subtle current breaks that walleye use to ambush prey. Jigging with crawlers or running slip bobbers with leeches are both working, and like Hauser, the late evening bite is where the action really heats up. If you’re not on the water at dusk, you may be missing the best window of the day.
Rainbow Trout: Multiple Methods Producing
The diversity of effective trout techniques on Holter right now is notable. Trolling flashers and spinner combos at 15–20 feet is producing good numbers throughout the reservoir — this depth range likely corresponds to where cooler, preferred water temperatures are holding. But the report also highlights fly fishing success on the upper end with midge nymphs, and shore fishing with worm-and-marshmallow combos at Departure Point and other public access areas. That range of productive methods suggests trout are distributed and actively feeding, which is great news regardless of how you prefer to fish.
Kokanee: Go Deep, Go Early
Kokanee are a special target at Holter, and their current location — 40 to 50 feet deep near the dam — reflects their preference for cold, oxygenated water. Dodgers and hoochies, or wedding rings tipped with corn, are the standard kokanee setup. The dodger provides the flash and erratic action that triggers kokanee, while the trailing lure imitates a small forage item. Early morning is the prime window, as kokanee often rise slightly shallower during low-light periods before retreating to depth as the sun climbs. If kokanee are on your list, plan for a pre-dawn launch.
General Tips for Fishing the Missouri River Reservoir Chain
- Check wind forecasts carefully. All three reservoirs — especially Canyon Ferry — can become dangerous quickly when afternoon winds pick up. Plan your trips around calmer morning windows and be prepared to head in early.
- Verify current regulations before you go. Species-specific limits, gear restrictions, and access rules can change. Always check the current Montana FWP fishing regulations before heading out.
- Match your presentation to the conditions. Stained water calls for brighter colors and more vibration; clear water often responds better to natural colors and subtle presentations.
- Public access is abundant. FWP and the Army Corps of Engineers maintain numerous boat ramps and fishing access sites on all three reservoirs. Most are well-maintained and free to use, though some require a fishing access site license — again, check current FWP guidelines.
- Keep an eye on the thermocline. As summer progresses, a distinct temperature layer will establish itself on all three reservoirs. Species like kokanee and trout will increasingly relate to that layer, so understanding water temperature and depth becomes more important week by week.
Bottom Line
The mid-June window on Canyon Ferry, Hauser, and Holter is genuinely one of the better periods of the year to be on the water. Walleye are feeding hard, rainbows are accessible by multiple methods, kokanee are responding to deep trolling at Holter, and the carp spawn at Canyon Ferry offers a bonus experience you won’t find at most Montana fisheries. Whether you’re chasing a single species or looking to mix it up across multiple reservoirs in a weekend, the Helena-area chain has you covered right now. Get out there.
