If you've ever spent a quiet morning trolling deep water without so much as a nudge, it might be time to start using cowbells for lake trout. For those who haven't seen them before, they look a bit like a mobile you'd hang over a baby's crib, except made of shiny metal and designed to be dragged through the dark, cold depths of a lake. They aren't actually lures that fish bite; they're attractors. They create a massive amount of flash and vibration that acts like a dinner bell for hungry Lakers, pulling them in from distances where a lone spoon or minnow might just go unnoticed.
I'll be the first to admit that trolling with cowbells isn't exactly "finesse" fishing. It's heavy, it's loud, and it feels a bit like you're dragging a boat anchor behind you. But when the bite is slow and the fish are scattered across deep basins, there's almost nothing more effective at waking them up. If you want to put meat on the table, you really can't ignore the power of a big string of blades.
What Exactly Are Cowbells?
In the world of lake trout fishing, cowbells are a type of "trolling flasher" or "lake troll." They consist of a long wire or cable—sometimes several feet long—with a series of metal blades attached to it. These blades spin as you move through the water. They don't have hooks on them. Instead, you attach a leader of monofilament or fluorocarbon to the end of the cowbell rig, and that's where your actual lure goes.
The name comes from the way they look and, to some extent, the amount of commotion they make. While they don't literally ring like a bell, the vibration they send through the water column is intense. Lake trout have a highly developed lateral line system, which allows them to "feel" movement and vibrations in the water. To a Laker, a set of cowbells for lake trout looks and feels like a panicked school of baitfish. They see the flash, feel the pulse, and come charging in to see what all the fuss is about. By the time they realize it's just some spinning metal, they've already spotted your trailing lure and—hopefully—inhaled it.
The Setup and Rigging
Rigging up cowbells for lake trout isn't complicated, but it does require some beefy gear. Because these rigs create so much drag, you can't really use a light spinning rod. You're going to want a dedicated trolling rod with some backbone and a reel that can handle a decent amount of lead core, copper line, or a downrigger setup.
The standard setup goes like this: your main line attaches to the front of the cowbell rig. Then, at the back of the rig, there's usually a swivel where you tie your leader. The length of this leader is one of those things fishermen love to argue about, but generally, 18 to 36 inches is the sweet spot. If the leader is too long, the fish might see the blades but miss the lure. If it's too short, the turbulence from the blades might actually spook the fish or make it hard for them to target the bait.
As for what to put at the end of that leader, small spoons, spin-and-glows, or even a simple piece of cut bait or a minnow works wonders. Since the cowbells are doing all the "calling," the lure itself doesn't always need to be huge. It just needs to look like a straggler from the school that's easy to pick off.
Choosing the Right Blades
When you start looking at cowbells for lake trout, you'll notice a ridiculous variety of blade shapes and colors. You've got your classic hammered silver, brass, copper, and even some wild painted patterns with "eye" stickers on them.
Hammered finishes are a personal favorite because they reflect light in dozens of different directions. In the deep, dark water where Lakers hang out, every bit of light helps. Silver is usually the go-to for bright, sunny days when there's a lot of light penetration. If it's overcast or you're fishing particularly deep, brass or copper can sometimes produce better results because they have a warmer, more subtle flash that doesn't overwhelm the fish.
The size of the blades matters, too. Larger blades create more vibration but also significantly more drag. If you're fishing in a smaller boat or using lighter downrigger weights, you might want to stick to a smaller series of blades. However, if you're hunting for a real trophy, don't be afraid to go big. Sometimes it takes a lot of noise to get a big, lazy trout to move off the bottom.
Speed and Depth Control
Trolling speed is probably the most critical factor when using cowbells for lake trout. If you go too fast, the blades will spin so violently that they start to tangle or even cause the whole rig to rise too high in the water column. If you go too slow, they just kind of hang there like dead weight.
Typically, you're looking at a speed between 1.0 and 2.0 miles per hour. A good way to tell if you're in the "zone" is to watch your rod tip. It should have a steady, rhythmic throb. That's the vibration of the blades doing their job. If the tip is vibrating erratically, you might have a tangle or some weeds caught on the line.
Depth is the other half of the equation. Lake trout love cold water, usually staying below the thermocline. In the heat of the summer, that might mean they're sitting 60, 80, or even 100 feet down. Using a downrigger is the easiest way to get cowbells to those depths, but lead core line can also get the job done if you're patient and have enough line out.
The "Love-Hate" Relationship with Cowbells
Talk to enough anglers and you'll find that cowbells are a bit controversial. Some people absolutely love them because, frankly, they catch fish when nothing else will. Others find them a bit tedious. The main complaint is that once a fish is hooked, the drag from the cowbells makes it hard to actually feel the fish fight. You're essentially winching in a piece of metal and a fish at the same time.
It's a valid point. If you're looking for the thrill of a light-tackle battle, cowbells probably aren't for you. But if you've been skunked three trips in a row and you just want to see a Laker on the floor of the boat, you'll be glad you have them. There's also a certain skill in managing the gear—preventing tangles and keeping everything running straight—that can be quite rewarding in its own way.
Why They Are Especially Good for Lakers
Lake trout are notorious for being somewhat sluggish compared to their cousins, the rainbow or brown trout. They spend a lot of time hovering near the bottom, conserving energy. They aren't always actively hunting; sometimes they're just waiting for an opportunity.
Cowbells for lake trout work so well because they trigger an instinctive predatory response. It's like a "frenzy" in a box. Even a trout that isn't particularly hungry might be annoyed or curious enough to come investigate the massive amount of vibration moving through its territory. Once it's in close, the sight of a fluttering spoon or a trailing minnow is often too much to pass up.
A Few Pro Tips for Success
If you're going to give this a shot, keep a few things in mind. First, always use high-quality ball-bearing swivels. Cowbells spin a lot, and if your swivels aren't top-notch, you are going to end up with a twisted mess of a line that you'll eventually have to cut and throw away.
Second, pay attention to your turns. When you turn the boat, the cowbells on the inside of the turn will slow down and sink, while the ones on the outside will speed up and rise. This is often when you'll get a strike, as the change in speed makes the "bait school" look like it's breaking up or weakening.
Finally, don't be afraid to experiment with the distance between your downrigger ball and the cowbells. Sometimes keeping them tight (maybe 10-15 feet back) works best, while other days the fish are spooked by the boat and you need to drop them back 50 feet or more.
At the end of the day, using cowbells for lake trout is a time-honored tradition for a reason. They might not be the fanciest or most modern piece of tech in your tackle box, but they have a track record that's hard to beat. Next time you're out on the big water and the fish seem to be giving you the cold shoulder, clip on a string of blades and start making some noise. You might just find that the "dinner bell" is exactly what those trout were waiting for.
