Fifty Fly Fishing Tips: #39 — Look Upstream to Find the Seams

by | Apr 22, 2018 | 3 comments

The river is in motion. It carves a path that erodes its rocky bottom and gnaws at its bordering banks. It cuts lanes and moves channels, constantly shaping the valley into something new. And within the river’s path is structure — all the things that give a river character: logs, tree parts, rocks, boulders, gravel bars and rootsy banks. That structure forms seams where trout live. (Find the seams and you’ll find fish.) And the best way to see them . . . is to look way upstream.

One of my favorite things about guiding is how much I learn from others. Sure, it’s rewarding to share my knowledge and experience with other anglers and see those friends catch fish as a result. But trout fishing is the kind of thing where every angler does something unique. No matter the level of experience, every fisherman has something different and valuable to bring to the game. It may be the way a guy stores his split shot or his different take on casting into the wind. But everyone I fish with has something to add. You don’t have to be an expert to have great ideas.

Likewise, good teachers understand that the process of communicating our own ideas strengthens what we already know. It forces us to reconsider and reevaluate our own beliefs. On the stream, it’s educational for me to see through another’s eyes. Without the rod in my own hand, my perspective changes. I see what my friend sees. And sometimes, I notice what he doesn’t see.

Short Sighted

I got my driver’s license at sixteen. And since I’d been driving lawn mowers, tractors and bicycles for most of my young life, I figured a car was, ya know, about the same thing. I was wrong about that. And it took some close calls and sketchy errors for me to learn a few things.

My Dad was a patient and perceptive teacher, and one relevant moment stands out. It happened just a few days after I got my license . . .

With Dad in the passenger seat, we traveled a local two lane road with my two hands on the wheel. Things were going fine until another car pulled onto the road about a hundred yards ahead of us.

I never saw it.

Dad waited a few tense moments and then said firmly, “Brakes!” We slowed quickly, without incident. But as we traveled on, I felt Dad staring at me for a while.

“Where are you looking?” He asked.

I glanced at Dad, and then back to the road. “I guess I’m looking at the road in front of me, Dad.”

“Yeah, but how far?” He asked. “How far ahead are you watching the road?”

Only then did I realize that I’d been scanning the road just a hundred feet ahead — about the same distance you might look ahead while steering a lawn mower, tractor or bicycle. My focus required some adjustment.

I think you can see the river analogy coming . . .

Reading the Seams

The structure in your favorite large river or small brookie stream creates seams extending well beyond what is obvious. The two distinct lanes running along each side of a midstream boulder create a third zone, a stall, right in the middle. It’s easy to see those three water features up close to the rock, but the further downstream the water travels, the more those features fade and blend into each other. And such is the beauty of a trout stream.

But the effect of those seams lasts further downstream than the untrained eye might see. The seams are still there, downstream of the structure, even when they aren’t so obvious. And those lanes, those seams, are a reliable target, well beyond what may be evident. Eventually, the seams blend into a new feature, affected by the next log, rock or gravel bar. And once again, the effects of that structure are found well downstream of what is easily seen.

So as you wade upstream, as you float downstream in a drift boat, or as you stand on the bank waiting for rise forms to signal the evening spinner fall, look upstream. See what’s ahead — further ahead — and consider the effects rendered on the water in front of you.

All rivers are a procession of lanes, dividing and merging to infinity.


Enjoy the day.

Central Pennsylvania

Hi. I’m a father of two young boys, a husband, author, fly fishing guide and a musician. I fish for wild brown trout in the cool limestone waters of Central Pennsylvania year round. This is my home, and I love it. Friends. Family. And the river.

Nobody Home | Nobody Hungry

Nobody home means there’s no trout in the slot you were fishing. And sometimes that’s true. Nobody hungry suggests that a trout might be in the slot but he either isn’t eating, isn’t buying what you’re selling, or he doesn’t like the way you are selling it.

Does it matter? It sure does!

New Structure | Old Structure

New Structure | Old Structure

One of my favorite places in the world is a deeply shaded valley that runs north and south between two towering mountains of mixed hardwoods. The forest floor has enough conifers mixed in to block much of the sunlight, even in the winter. The ferns of spring grow tall, and thick moss is spread throughout. The ground remains soft enough here that all large trees eventually surrender to the valley. When they can no longer support their weight in the soft spongy ground, they fall over, leaving a broken forest of deep greens and the dark-chocolate browns of wet, dead bark. It’s gorgeous.

Fallen timber also dictates the course of this cold water stream. The fresh tree falls force the creek to bend away from the hillside. Rolling water carves away the earth and lays bare the rocks — these stones of time, as Maclean puts it. And when water cuts into a neighboring channel, previously dry for centuries, new river banks are undercut and fresh roots exposed . . .

What Lies Beneath

What Lies Beneath

There’s a world unseen below the surface. The riverbed weaves a course and directs the currents, giving shape to its valley. Water swirls behind rocks. It moves north and south against submerged logs. The stream blends and separates, merges and divides again as vertical columns rise and fall — and all of this in three dimensions. . . . Eventually, knowing and admiring what lies beneath is as easy as seeing what flows above.

The Water Column — And the All-Important Strike Zone

The Water Column — And the All-Important Strike Zone

Seeing into the river is a learned skill. It takes a lot of time on the water to judge the three dimensional flow of a river. Reading the surface is easy. Even without bubbles on the top, most anglers quickly learn to gauge the speed of the top current in relation to their fly or indicator. But what lies beneath can be unpredictable and deceiving. Eventually, with the help of polarized lenses and some serious thought, experienced anglers become proficient (enough) in reading the currents below.

But where does it begin?

Understanding a little about the water column and the correlating habits of trout goes a long way toward better fishing. So let’s do it . . .

Fly Fishing Tips: #54 — Don’t let a good bite teach bad habits

Fly Fishing Tips: #54 — Don’t let a good bite teach bad habits

Fly fishing provides so much variety in presenting flies to a trout that a good and well-rounded fly angler can make something happen, even on the slowest days — usually. And so, we spend our time on the water learning and refining these various techniques with dry flies, nymphs, streamers and wets, waiting for the trout to turn on, but fishing always with persistence and hope flung into each cast.

I’ve been around enough long-term fishermen to understand one primary character trait — we all approach the water with an effort to learn. That’s what keeps things fresh year after year. That’s what keeps a man fishing from childhood to the grave. It’s not the trout, but the process of discovery, the perfection of tactics that will never be good enough to make a sure thing out of a day on the river.

Every angler finds moments when the fishing is easy, when seemingly any decent presentation of the fly brings a fish to hand. Even the most difficult rivers give up a good bite once in a while. And the easiest rivers, with eager trout, produce great bite windows that last for hours or even days. But what should we learn from that? . . .

Fly Fishing Tips: #53 — Nymphing: Set On Anything Unusual

On a first drift through the lane, you may very well set on anything. But maybe that line hesitation was just the flies ticking the top of a rock. Good. Now you know.

Don’t set on anything. And don’t wait for a sixth sense to kick in and grant you the superpower of sensing trout takes. Instead, pick a lane and learn it. Use the nymph as a probe to draw a mental map of a specific lane. Refine the drift. And all the while, set on anything unusual.Let’s break it down real quick . . .

  1. “No matter the level of experience, every fisherman has something different and valuable to bring to the game”….so true….the best thing about fishing with friends.

  2. Wow. This is an insight I’m glad I came across. When the seam ends I always thought that was the end of the story but evidently not. Makes complete sense when you think about it, something I don’t do enough of when I’m on the stream.
