Canyon Ferry doesn’t get enough credit. Most anglers outside of the Helena Valley think of it as a walleye lake and leave it at that — but the reservoir sitting just 20 miles east of Helena has been quietly growing some serious rainbow trout alongside those walleye slabs, and when both species cooperate on the same trip, you’ve got yourself a day worth filming. That’s exactly what the crew from Water Less Traveled put together in their latest episode, and it’s worth your time whether you’re planning a trip out there this summer or just want to see what’s swimming around in one of Montana’s most underrated fisheries.
Canyon Ferry Reservoir covers roughly 35,000 acres when full and is managed jointly by Montana FWP and the Bureau of Reclamation — making it fully accessible public water with multiple boat ramps, including the popular Hellgate and White Earth access sites. FWP has stocked rainbow trout in Canyon Ferry for decades, but the fish showing up in recent seasons have been something different. The combination of abundant forage — primarily yellow perch and cisco — and the reservoir’s depth has been producing trout that look more like something you’d pull out of Flathead Lake than a plains reservoir. The walleye fishery, meanwhile, has been self-sustaining and strong since the 1990s, with consistent year classes producing fish in the 14–20 inch range and occasional genuine trophy-class walleye pushing well past that.
From a regulations standpoint, Canyon Ferry falls under FWP’s Region 4 rules. The current walleye daily limit is 10 fish, of which only 1 may be over 15 inches, though keeping the biggest ones is a personal call you’ll have to make. Rainbow trout carry a 5-fish daily limit. If you’re heading out this summer, mornings and evenings have been the sweet spots — walleye push shallow in low light, and the rainbows have been holding along the main basin drop-offs and near the dam face. A lot of local anglers have been running crawler harnesses and jigging with plastics for the walleye while switching to Rapalas and spoons for the trout. The Water Less Traveled crew shows their approach in detail, which makes this video genuinely useful as a scouting tool, not just entertainment.
Canyon Ferry is the kind of place that rewards the angler willing to experiment. It’s close to Helena, the camping is solid at the state-managed campgrounds along the east shore, and the scenery — with the Big Belt Mountains rising up to the east — isn’t bad either. If you haven’t been out there lately, this video might be the push you needed. Give it a watch and then go check the conditions yourself.
Editor’s note: Corrected the Canyon Ferry walleye limit: the daily limit is 10 walleye but only 1 may be over 15 inches, per 2026 Montana regulations.
