Chasing Steelhead on the Niagara: Swinging Intruder Flies When the Creeks Run Low

A Long Shot on the Niagara: Two Steelhead on the Swing

Some fishing trips are built on careful research, scouted runs, and methodical planning. And then there are the other kind ?" the ones where you show up half-expecting failure, armed with little more than a homemade fly and a stubborn refusal to stay home. For South Mend, a recent session on the Niagara River turned out to be exactly the latter kind, and it delivered one of those rare days that reminds even seasoned anglers why they keep coming back to the water.

The setup wasn't exactly promising. Local creeks were running super low and clear, draining any real possibility of a productive swing. Without meaningful current, swinging flies becomes an exercise in futility ?" a fly needs to breathe, to arc across the water column with purpose. So rather than bang away at dead water, South Mend made a calculated gamble and headed for the Niagara River, where at least the current had something to say for itself.

"This might be either the dumbest or the smartest idea I've had," he admitted before wading in. "Probably the dumbest."

He was wrong about that. But only just.

Why the Niagara?

The Niagara River is not your typical steelhead destination ?" at least not in the way that Pacific Northwest rivers or well-known Great Lakes tributaries tend to dominate the conversation. Running between Lake Erie and Lake Ontario along the border of New York and Ontario, the Niagara is massive, powerful, and often overlooked by fly anglers in favor of smaller, more manageable tributaries. Its sheer size can be intimidating, and finding the right current seams for a proper swing demands both local knowledge and a willingness to experiment.

On this particular day, that willingness was the whole plan. With the tributaries written off, the Niagara at least offered current ?" the essential ingredient for swinging flies. The goal, realistically, was smallmouth bass. Steelhead weren't even on the radar. Late in the season, after spawning runs have largely wound down, the idea of intercepting a steelie on a swung fly in the big river felt like a stretch at best.

The Fly: An Emerald Shiner Imitation

Before hitting the water, South Mend had tied up something special for the occasion ?" a single-station intruder-style fly designed to mimic an emerald shiner, one of the Niagara's most abundant and important forage fish. Emerald shiners are a staple in the diets of virtually every predatory species in the river, from smallmouth bass to walleye to, as it would turn out, post-spawn steelhead looking for an easy meal.

The fly itself was built around movement and profile rather than strict imitation. A 4mm tungsten cone gave it weight and ensured it would get down into the water column where fish were holding, while the intruder-style construction ?" even at just one station ?" allowed the materials to breathe and pulse with the current. It was paired with a Scientific Anglers Sync 7 integrated Skagit head and a TC tip, a setup well-suited to cutting through heavy current and presenting a fly at depth.

"It's kind of hard to see when it's wet like that," he noted, holding the fly up after the fact, "but it's like an emerald shiner imitation. And he just absolutely smacked that thing."

The choice to match local forage rather than default to conventional steelhead patterns proved to be the kind of small decision that makes a very large difference.

Finding the Current ?" and the Fish

The first spot South Mend tried was slack, the current too soft to give the fly any real life. A few passes confirmed what the water was telling him, and he moved on, searching for the kind of seam where current accelerates around structure or transitions from deep to shallow ?" exactly the type of lies where steelhead tend to park after the rigors of spawning.

When he found it, the difference was immediate. The fly swung with purpose, arcing through the current in that hypnotic, suspended way that makes swinging flies one of fly fishing's most addictive disciplines. And then, without warning, the line came tight.

"I was not expecting to actually hook up," he said, the surprise evident in his voice. "That was an aggressive take."

His first instinct was smallmouth ?" a reasonable assumption given his expectations for the day. But as the fish revealed itself, the truth hit him like a freight train.

"Oh my god. It's a steelhead, dude. No way. Oh my god. Sorry, I'm freaking out."

The First Fish: A Tired Warrior

The steelhead that came to hand was a drop-back ?" a fish that had already completed its spawning run and was making its way back toward Lake Ontario. Post-spawn steelhead, often called drop-backs, can be notoriously lethargic. The metabolic toll of the spawn, combined with weeks of fasting and fighting current, leaves them running on reserve. This fish was no exception, offering little resistance and coming to net with the quiet dignity of a fish that had already done the hard work of the season.

It wasn't a trophy fight, but the fish itself was a trophy moment. Standing on the Niagara's edge, holding a steelhead he had never once anticipated catching when he left the house that morning, South Mend found himself genuinely lost for words.

"I am at a loss for words here. I was expecting only smallmouth at the most today, but lo and behold, there's some steelhead just chilling in that quicker current."

He photographed the fish, took a moment to absorb what had just happened, and slipped it back into the current. Then, because any sane angler would do the same, he picked up his rod and kept fishing.

The Second Fish: A Different Story

If the first steelhead was a pleasant shock, the second was something else entirely. After wading back out and resuming his swing through the same current seam, South Mend hooked up again ?" and this fish had more left in the tank.

A big, dark buck, well into the post-spawn color change that turns steelhead from chrome bullets into deep, burnished creatures of a different character entirely, this fish used the current with authority. Where the first fish had surrendered quickly, this one ran, tested the drag, and had South Mend working upstream and applying side pressure to steer it to the net.

"That's the fired-up steelhead I was looking for," he said, laughing through the chaos. "He is definitely all spawned out ?" but it is a pretty big buck."

After a proper battle, the fish was netted, the fly was removed, and the moment was documented. South Mend had already filmed what he thought would be his outro after the first fish. Now he needed a new one.

"I just filmed the outro, so I'm going to have to film another outro. Bro, what? This is insane."

What This Session Reveals About Swing Fishing

Beyond the raw excitement of an unexpected double, South Mend's session on the Niagara offers a few worthwhile lessons for fly anglers willing to think outside the box.

First, current is everything when it comes to swinging flies. The decision to abandon the low, slack creeks in favor of the big river's moving water wasn't just logical ?" it was the reason the whole day worked. Steelhead and other predatory fish orient to current, and a swung fly without meaningful flow is simply a fly going nowhere.

Second, matching local forage matters, even when you're not targeting a specific species. The emerald shiner imitation wasn't tied with steelhead in mind, but it didn't need to be. It looked like food, it moved like food, and the fish responded accordingly. In waters where baitfish are abundant, a well-tied baitfish pattern will often outperform species-specific approaches.

Third ?" and perhaps most importantly ?" the unexpected is always possible when you put the fly in the water. Post-spawn steelhead lingering in a big river's faster current aren't the quarry most anglers are thinking about in late spring. But they're there, and they eat.

Gear and Setup

For anglers looking to replicate this approach on the Niagara or similar big-water environments, South Mend's setup is worth noting in detail. He fished a switch rod paired with a Scientific Anglers Sync 7 integrated Skagit head ?" a compact, versatile shooting head format that loads quickly and handles heavy tips without demanding the long back-casting stroke of a full Spey line. The running line was matched with a Scientific Anglers TC (tungsten carbide) tip, which gets the fly down efficiently in deeper, faster currents without sacrificing the natural swing angle.

The fly itself featured a 4mm tungsten cone at the head ?" heavy enough to ensure the pattern fished at the right depth through the swing, but not so heavy that it killed the movement of the materials. For anyone tying a similar emerald shiner imitation, the key is keeping the profile slim and the materials lively: craft fur, marabou, or similar synthetics that undulate with minimal current input.

A Day Worth Remembering

By any objective measure, South Mend's session on the Niagara River was improbable. He went looking for current when the creeks ran out of it, tied on a smallmouth fly, and ended up landing two steelhead on the swing in a river he had never swung flies in before. The whole thing unfolded in the span of a short afternoon, with just enough time left to film two separate outros and still make it home at a reasonable hour.

"Man, I really thought I was not going to be able to hear the drag of this reel until the fall when steelhead season starts again," he reflected. "Two steelhead. First time swinging the Niagara. That is crazy to me."

He's right that conditions aligned in a way that may be difficult to reproduce ?" low water in the tributaries pushing fish to hold in the main river, just enough post-spawn fish still lingering to intercept a well-presented fly. But that's the nature of fishing. You can't manufacture the perfect day. You can only show up, make your best decisions, and let the river do the rest.

On this afternoon, the Niagara delivered. And somewhere out there, a pair of dark, spawned-out steelhead slipped back into the current and kept swimming toward the lake ?" completely unaware of how thoroughly they had made someone's day.
