Canyon Caddis

by | Apr 25, 2021 | 12 comments

The flow of the river followed the curve of the valley wall. A huge, flat, vertical sheet of rock provided a bumper, as the streamflow deflected against the limestone karst. Then it dramatically changed directions. While the river we’d been fishing had been flowing west, it now flowed south. And that changed a few things.

Sunny days like these are never my favorite. My wife asserts that I’m a constant contrarian, but really I’m just a die hard fisherman. To me, good weather isn’t sunny. Instead, I like grey clouds more than blue skies, and I hope for rain while everyone around me seems to lament every drizzle — until they start complaining about a drought.

So I was glad that Smith and I had grabbed an early start. Just after dawn, the clear skies signaled a tough day ahead, and we both made mention of the budding but leafless trees on the walk in. That complicated the matter, as trout lacking shade wouldn’t have much chance to escape the direct sunlight.

These bright, early spring days can be some of the toughest of the year. With all sun and no shade, the wild brown trout here hold tight to the meager shadows of instream rocks and woody banks. Fish can be fooled with persistence and refinement, but I’m constantly thinking about where I can keep the sun out of the trout’s eyes. And I knew the rock wall was one of those places.

So around noon, I’d gathered Smith from the downstream end of some pocket water, where he was clearly setting up to fish each likely seem with precision. But I knew the river better than my friend, as I’d spent twenty-some years fishing here, and Smith was a transplant to the area. So I waved him over, explained about the rock wall and led us upstream, over dead logs and along a meager deer path for a few hundred yards.

As we approached, Smith saw why I’d pulled him out of the prime water to move upstream. Here, against the shade of the limestone wall, thousands of fast wings flickered in the slanting light. Along a diagonal line, sunlight poured into the canyon. It was shaded for a stretch beyond the flat and wet wall, with sunlight expanding over the upstream half of the small canyon. A cloud of midges could easily be mistaken for fog if the hour wasn’t so far past morning. But a closer look showed thick clusters of midges swarming in a ball. They blended and merged with the neighboring airborne midge clusters. Watching it all could cause a disorienting loss of depth perception if you stared at it too long.

But the Grannom caddis stood out the most. Unlimited tent-winged insects flew and fluttered in and out of the sunlit air. Somehow, they never banged into each other while diving and dapping on the water’s surface, over and over. Most of these caddis were surely holdovers from the previous days. And now, warmed by the sun and having shed the morning dew collected on grey wings, they returned to the water to grab a drink by diving to the surface repeatedly. Many of the females were also dapping to lay eggs, dislodging their payloads by forcefully slamming their bodies onto the surface again and again. Some of these caddis were then swamped by the current or damaged by their acrobatic and reckless tumbling. And the broken ones didn’t last long. Large slurps from underneath signaled the feeding of the biggest trout, keying in on the opportunity for an easy meal.

Smith and I shared a smile at the sheer number of good chances. Trout often ignore top-water caddis, because the emerging insects spend very little time on the surface, and trout don’t like to chase too often. But with a blanket hatch like this, the odds stack up, and trout were taking notice.

The slurps happened about every twenty seconds, spaced out along the span of the shaded rock wall. The water there was flat but alive, rocking and settling in waves as the new water from upstream merged with the water returning from the wall. Then it all mixed and redirected to follow gravity, south into the next heavy run. Those slurps stood out to us because our eyes had been trained to pick out the biggest rise forms, but the splashes of smaller trout were there too, in numbers tenfold. These were aggressive fish, willing to take a shot at the moving prey of dapping caddis. And they would also be fun targets for our flies.

Smith and I spent the afternoon fishing and re-fishing the same fifty yards of water. In the next three hours, there was rarely a time when at least one of our fly rods wasn’t bent over with the weight of a trout.

We were joined by dozens of birds that more often picked off the occasional Hendrickson mayfly, which neither Smith nor I noticed until the very end, when a particularly stubborn trout turned down both the X-Caddis and the CDC and Elk that we’d had in rotation. Smith stopped casting long enough to study the riser for a few minutes, and he saw the trout eat one of the few Hendricksons on the water. A quick change to a classic Adams fooled that fish too.

The fishing and the friendship that day was unforgettable.

Fish hard, friends.

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.

Saltbitten: Thoughts and Lessons from the Summer Surf

I’ve lost good friends in the last year whom I know had plans that remain eternally unfilled. I used to think time was the enemy. I was wrong. The end is the enemy. And time is all I have to work with.

. . . I love the details of saltwater fishing. I love the sunrise and the sunset. I love the never-ending wash of good waves. I love having my bare feet in the ocean for hours at a time with nothing in front of me but the endless ocean until it meets the soft line of the horizon. I love the walk back, watching beachgoers enjoy their own moments, seeing their friendships and laughter. I love being by myself, and I love sharing the sand with my boys . . .

Fishing Tempo

Fishing Tempo

Much like a musician might play the same song Largo or Allegro, an angler can fish methodically, even and calm, or he can fish the same meandering series of undercuts with earnest intensity, cutting through water at twice the pace and delivering the fly with acute precision.

Both have their beauty. Elegance is found in either approach, if an angler is on their mark.

Shirt Pocket Fishing

Get the cast perfect the first time, or the trout will pull themselves out of position to check your fly, then turn as it drags away. In these conditions you never get a second chance.

It’s technical, but fair. It’s unforgiving, but fun. It’s a new lesson at every undercut, and the whole thing’s over by 10:30 a.m

Can You Create Your Own Hatch?

Can You Create Your Own Hatch?

The truth is, I do not think you can create a hatch. But I’ve had enough fun through the years, testing the concept in key spots at specific times, that I keep doing it. Because every once in a while, those extra drifts have seemed to make a difference.

. . .But creating an ant hatch makes me feel like Brad Pitt (maybe like a dollar-store version). And it seems to spark the curiosity of a trout once in a while, just as it satisfies some odd curiosity in me. o.

What’s the Most Fun Thing About Fishing?

What’s the Most Fun Thing About Fishing?

Our objective while fishing is to catch a fish. That’s the point. And as catch-and-release anglers, we don’t fish to put food on the table. We fish . . . because it’s fun.

We can all list a hundred other reasons why we enjoy fishing. It’s the environments where trout live, the problem solving, the daily mystery, the beauty of the woods and the water, the therapy of being immersed in a river and a chance to interact with one of nature’s swimming creations.

But none of that means much without a win once in a while. Catching fish is the motivation. And without that reward, without the feedback that we’re doing something right and improving, all those other intangibles fade away fast.

Fish the Edges?

Fish the Edges?

More water means more food and more opportunity for a trout to use the whole river, from bank to bank, for feeding in the drift and for ambushing bigger food forms.

. . . So, fish the edges when big flows are recent. Fish the edges too when water clarity is at its worst, because slow seams near the bank often have the best chance to clear up, as sediment falls out of the current.

. . . However, given high water with decent clarity, I do not fish the edges any more than normal. And during the last few months here, I’ve caught more trout in the main flow than in the bank water.

  1. So on Truckee fish just don’t surface feed very often,regardless of hatches,so 90% is nymphs. Have started to notice those big caddis bombing the surface,and since my mayfly style nymphs have slowed way down wondering what caddis nymphs have worked for you?

  2. Once in awhile we get blessed,had a late afternoon on the Green river WY.
    watched in amazement, so many fish.

  4. Great article!
    Love those days.
    Just curious, what Caddis is the one called the Mothers Day Caddis? Just trying to be best prepared size wise and color wise/pattern wise for it.
    Then I can confidently tie up a mess of them for when the time comes.

  5. Question Dom,
    I’ve only come across 1 problem with my mono rig setup. When fishing in the rain or when my rod gets wet(I’m using an Aventik Escape 10’3″ 2/3wt rod),I have problems with the mono sticking the rod. I’ve cleaned and coated the rod,I’ve tried waxing and buffing,I’ve clean and treated the mono line like regular fly line and I just can’t seem to find a solution, other than using a different rod which isn’t always practical, any ideas??

    • Hi Dean,

      What you describe is an acknowledged downside with a Mono Rig. It can happen in the rain.

      Some anglers spiral-wrap 3X tippet all the way down their rod, from tip to butt section to prevent the material from sticking. It’s a clever solution. I’ve done this a couple times, and it certainly works. However, I find it much easier to tackle the problem another way:

      Cast with speed. Do not lob but CAST these rigs, and that will mostly solve your issue. I recommend casting this way all the time, not just when it’s raining outside.

      Make sense?

      • even with speed / hauls it will still become an issue with microthin leaders, usually below 10lb chameleon, at least in mu experience. i spiral wrap 1x mono tippet from the tip guide to near the cork and stick / hold that end in in place with self bonding silicon tape (underwater tape). i keep a small precut piece of that tape in my vest in case i need to wrap my rod in the rain (if i know the forecast is calling for significant rain i’ll wrap my rod the night before to save time)
