Flies: March Browns

So, I’m writing about March Browns not because they are necessarily of great significance to the Smoky Mountain fly fisherman, but mainly because they’re just really cool bugs! Like many aquatic insects in the Smokies, this mayfly does not usually hatch abundantly enough to really get the trout keyed in on them, but it is worth keeping a few in your fly box. In other words, you probably don’t need fifteen different March Brown patterns in subtly different colors. Having a few of a basic pattern should do the trick.

March Brown Dry Fly

March Browns are big, usually a #12 or #10 hook size, and they tend to be the first mayfly of the year with any color. Most of your early spring mayflies are some version of grey, but March Browns usually have a light, reddish brown body with handsomely mottled wings of brown, tan and even yellow hues. Contrary to what their name might imply, these mayflies don’t hatch in March. Rather, they tend to show up, at least in the Smokies, around the third week of April and hang around for the first half of May.

March Brown Nymph

The nymphs are probably the most important stage for Smoky Mountain fishermen. While they have flat clingy bodies with muscular legs, making them very strong crawlers, when they lose their footing, they are terrible swimmers and easy pickins for a waiting trout. The nymphs tend to inhabit moderate to fast riffles and vary in color from tan to reddish brown to dark brown. A Hare’s Ear Nymph or Pheasant Tail Nymph are good generic imitations. I’ve also included one of my favorite patterns designed to specifically imitate a March Brown nymph.

Nymphing these patterns should be fairly effective all day but particularly early in the morning. Expect to see the adults hatching from late morning to early afternoon with a spinner fall near dusk.

On the Fly: One Less Tangle

At the end of your fishing day, strip all of the loose coils of fly line from your reel and reel it back on tightly, using your fingers to apply pressure and guide the line evenly on the reel. This will ensure you begin your next fishing day tangle free!

Matching the Hatch

Probably 20 years ago, I was fishing the Clinch River with a buddy during the sulfur hatch. I won’t get into what has happened to that hatch, but back then, it was epic. Sulfurs would come off by the thousands for 4-6 hours a day for about 3 months. We would drive down from Kentucky to fish it and on most trips, we would both steadily catch fish, many topping 20”.

On this particular trip, the bugs were coming off as good as they ever had, the water was boiling with rises, but we were both getting blanked! We were both going through every type of sulfur dry, emerger, and nymph in the box, all with the same result. Frustration got the best of both of us and we headed to the bank for a smoke, a bad habit we both enjoyed back then. While staring at the river and scratching our heads, it hit us both at the same time as we simultaneously exclaimed, “They’re eating caddis!”

Caddisflies tend to emerge quickly and almost explode off the water. When a trout feeds on one, it will frequently chase it to the top to eat it before it gets away. Sometimes the momentum will cause the fish to come completely out of the water, but at the least, results in a very distinct, splashy rise – not like the delicate sipping rise to a mayfly. Once we stepped away from the river and watched, we both noticed it.

We went back to the water and began looking more closely. Sure enough, there were caddis hatching, too. There was probably one caddis hatching for every 100 sulfurs, but for whatever reason, the trout were keyed in on the caddis. It’s what is referred to as a “masking hatch.” We both switched to the appropriate caddis pattern and were immediately into fish!

That’s not the only time something like that has happened, and each occurrence has trained me to always pay attention and sometimes try to look past the obvious. Here are a few things I’ve learned along the way that may help you solve a hatch riddle sometime.

First, we have to address the basics. If you see fish rising and have a pretty good idea what they’re eating but you’re fly is being ignored, check to see that your fly is the same size as the naturals. Also be certain that your tippet is not too large and that you’re getting a good drift. Presentation is most often the culprit when your fly is being ignored. Next, make certain that the color is a close match to the natural. If you’re fishing a bushy pattern, you might try a more subtle pattern like a Comparadun. If that’s not working, try an emerger fished just under the surface or in the film.

Fish Rise

Still not catching them? Take a break and watch the water. You may be able to tell something from the rise rings as I described above. If you don’t learn anything from that, try to find a fish that is rising steadily and watch him. He’s probably feeding in rhythm, like every 10 seconds. Watch his spot and try to time his rises. When you have that down pretty close, try to see what he eats. You should be able to tell if it’s the same kind of bug you’re seeing in the air, or at the very least, whether he’s eating something on or just below the surface. It’s almost like detective work. You sometimes have to go through the process of eliminating suspects before you can zero in on your man!

If fish are actively rising but you don’t see any bugs in the air, check the water. Try to position yourself at the bottom of a feeding lane (downstream of where the fish are feeding) and watch the surface of the water (and just beneath) for drifting bugs. Holding a fine mesh net in the current is a great way to collect what’s coming down the channel, but if you don’t have one, your eyeballs will do just fine. If you see some insects, capture one and try to match it with a fly pattern.

Hatches are puzzles and that’s one of the things that makes them fun. Sometimes you solve it right away, sometimes it takes awhile. Just remember that while the fly pattern is a big part of the equation, it’s not the only one. As mentioned above, presentation is huge. In addition to your technique, a smaller tippet and/or a longer overall leader may be the solution. Also consider your approach.

While I typically like to cast upstream to fish so that I can stay behind them, they will sometimes shy away from your fly in slow runs if they see your line or leader. I will sometimes try to get above fish in slow runs and cast down to them so they are sure to see the fly first. You have to land your cast short of them with slack in the line, and feed slack to enable the fly to naturally drift to them. This is a challenging presentation and it is critical that you carefully position yourself out of the trout’s line of vision.
Again, it’s a puzzle and there’s not one universal solution to every challenge.

Pay attention to your technique and everything what you’re doing (or not doing). Most important, pay attention to the fish. They’ll usually tell you what to do!

Flies: Sulphurs

If you take East Tennessee as a whole, it’s pretty safe to say one of the most prolific hatches is the sulphur mayfly hatch. Southern tailwaters are generally not known for having significant hatches of mayflies, caddisflies, or stoneflies. When we think of most of these dam-controlled rivers, we typically think of crustaceans like scuds and sow bugs, and midges…. lots and lots of midges. However, one mayfly that hatches on all East Tennessee tailwaters, often in very big numbers, is the sulphur. And that means that your best opportunity to catch a really big fish on a dry fly around these parts is during the sulphur hatch.

On the South Holston, they hatch in huge numbers for nearly nine months of the year. They hatch on the Holston, Hiwassee, Watauga and Caney Fork, too. But when I think of the sulphur hatch, I think of the Clinch River, probably because it was the first really BIG hatch I ever fished as a fly fisherman.  And while it may not be quite as epic as it was 20-30 years ago, it is most definitely still a hatch worth making time for.

Parachute Sulphur

The hatch usually gets started in late April on the Clinch and often lasts well into July. May is the best time to fish it. In April, the bugs are usually just starting to trickle off fairly inconsistently.  By mid June, trout have been seeing these things come off by the thousands for 4-6 hours a day, for 6+ weeks. To say that they become selective is an understatement. But in May, bugs are coming off steadily and the trout haven’t yet learned to count the hackles on your fly before choosing to eat it. They don’t seem to care if it’s on the surface, in the film, or 2” below the surface. In July, that stuff matters! In May, pretty much any pale yellow, size #16 dry fly will do the trick if it’s presented on a dead drift.

Parachutes and Comparaduns tend to be the best choices for dry flies. And there are a host of more sophisticated emergers and cripples to fool the wary, late-hatch fish. Pheasant Tails in brown and olive are usually the best option for nymphs.

Beadhead Pheasant Tail

While exact time and duration varies, the sulphur hatch on the Clinch typically starts in late morning and lasts for 4-6 hours a day, taking you right up to happy hour. Drifting Pheasant Tails will pass the time in the morning while you’re waiting for the main event to start.

Sulphurs are a big deal in the mountains, too. While they won’t come off in the obscene numbers found on the tailwaters, they are still one of the better hatches of the year. In the mountains, the hatch usually lasts 3-4 weeks and tends to be more of an evening event. Many nights, the sulphur hatch will correspond with the Little Yellow Sallies’ return to the water to lay eggs, making for a fast and furious end to the day for those willing to fish through supper.

Flies: The Frenchie

In the last ten years or so, the term “Euro Nymphing” or “Czech Nymphing” has become more and more common, and is often billed as a revolutionary style of fishing. Basically, it is just nymph fishing without a strike indicator. It’s akin to what many for years have referred to as short-line or straight-line nymphing. Others refer to it as high-sticking. Or the old mountain fishermen around here just call it nymphing, because it’s how they’ve fished for decades and decades.

There is not a lot written about the history of fly fishing in the Southern Appalachians, and most of the techniques were just handed down generation to generation. I’ve had the pleasure and benefit of learning from many of these “old timers,” so when I first heard about this revolutionary style of fishing, I had to chuckle. There really is nothing new under the sun.

There are a few subtle differences in European nymphing techniques and what I learned to do. But what any trend will bring to the industry, no matter how long the method has been around, is the availability of new and better tools and equipment to perform the new trend. In this method of nymphing, you are really trying to keep your fly right on the stream bottom, which of course results in a lot more snags. Traditional jig hooks are great for this because they ride hook up, but until recently, haven’t been available in appropriate sizes and weights for fly fishermen.

Now there are a number of micro-jig hooks available that accommodate a special slotted tungsten bead. They are perfect for fly tying and I have begun tying a lot of my favorite nymph patterns on them. However, one of the first flies I tied on them, The Frenchie, is a pattern that did come from the “Euro-nymphing scene” and it has proven to be an effective trout pattern on a number of different waters.

It’s basically a Bead Head Pheasant Tail with a “hot spot” of bright dubbing at the head. The original pattern uses a bright pink dubbing for the hot spot, and that seems to work very well for stocked trout and even wild trout at times. In general though, I tend to have more success with wild trout using slightly more natural colors like yellow or green.

Again, it’s greatest value is that it has plenty of weight and rides hook up, so you can get it down deep with far fewer bottom snags. Pick some up and give them a try next time you’re out. And if you’re a fly tyer, I’d recommend trying some other favorite nymphs like Pheasant Tails and Hare’s Ears on these hooks.

Flies: The Hidden Terrestrials

We often hear about the importance of fishing terrestrials in the summer months. Out west, the conversation usually focuses on hoppers. Around here, we talk more about beetles, ants, and inchworms.   Regardless, there are a number of land-based insects from beetles, ants and hoppers to cicadas, bees and black flies that find their way into the water during the summer months.

Just the other day on a guide trip, a customer caught a brook trout that had a mouth full of small beetles. The fish had obviously been very recently gorging on them, but if you studied the surface of the water in that pool, you’d have a tough time finding a single beetle on the water. You would also be challenged to see ants, inchworms, or any other terrestrial. However, if you used a bug seine in that same pool, you would get an entirely different picture.

The fact is these land-based insects are not particularly good swimmers. Most of them, particularly ants, beetles and inchworms, briefly attempt to swim on the surface of the water but soon are caught by currents and swept below the surface.   But nearly every fisherman who fishes terrestrials, fishes them on the surface… and for good reason. Nearly every fly shop or fly manufacturer almost exclusively sells topwater terrestrial patterns. And most of these are constructed of foam or some other highly buoyant material to make the fly ride high on the water.

While you can certainly catch plenty of trout on these patterns and have a blast doing it, you are missing out on A LOT of fish. If you are a fly tier, try tying a few ants with a dubbed body and a hen feather rather than foam and hackle from a rooster neck. Tie some beetles without the high-vis sighter on the back and instead add a few wraps of lead wire. If you don’t tie flies, place a split shot above your favorite terrestrial pattern next time you go fishing.

A great way to fish them in pocket water is with a straight-line nymphing technique, allowing them to swing at the end of the drift. In pools, fish them a few feet under a strike indicator. Or tie on one of those big, buoyant foam hoppers and drop a submerged beetle or ant about 15” off the back. I probably use this method more than any other.

Flies: Wooly Bugger

Leech? Stonefly? Hellgrammite? Minnow?

Ask any fly fisherman with any experience at all to name his top ten, “must have” flies and I guarantee that 9 out of 10, at least, will include a Wooly Bugger. And the handful who don’t mention it are likely just contrarians. But why? Why is this such a popular fly that is a staple in nearly every angler’s fly box?

I suppose everyone might have their own answer to that question, but for me, the short answer is versatility. The Wooly Bugger was one of the first flies I ever learned about and with it, over my many years of fly fishing, I’ve caught rainbow trout, brown trout, brook trout, largemouth bass, smallmouth bass, white bass, rock bass, mooneye, carp, catfish, crappie, bluegill, striper, gar, walleye, and salmon. And I’ve caught fish with it in lakes, ponds, deep rivers, shallow mountain streams, and tailwaters. I suspect the only reason I’ve never caught fish on it in saltwater is that I’ve never tried.

This one could easily pass for a crayfish

What’s it supposed to be? That’s the beauty of it. Depending on how you tie it and how you fish it, it can represent a number of food items. For instance, tied in black and retrieved slowly, it probably represents a leech. Tied in lighter colors and stripped more quickly and erratically, it looks like a baitfish. Tied in a combination of olive and/or rusty colors, it resembles a crayfish. Tied in darker colors and fished on a dead drift, it could imitate a stonefly or hellgrammite nymph. Tie it in bright colors, maybe with an egg on the front, and you have a fly for salmon, steelhead, or many stocked trout.

Try this purple and pink Bugger for winter stockers

Because of its versatility, it could be mentioned as a recommended fly for any month of the year. I selected it for November for a couple of reasons. One, there are just not many hatches or any unusual flies to single out in November. Two, this is one of the big months to fish for large browns in the park. Post spawn brown trout are hungry and winter is coming soon. While you can certainly catch them on smaller flies, why not show them a little bigger meal? Wooly Buggers are big fish flies. At the end of the day, that’s probably the real reason it’s such a successful fly – because it looks like a big meal.

Next time you’re not sure what the fish are biting on, tie on a Bugger. Dead drift it in a riffle. Strip it through a deep flat. Play with it. You may be surprised what you find!

Flies: Little Yellow Sallies

Yellow Sally Adult

April is one of the busiest months of the year for hatches and provides a smorgasbord of bugs for our finned friends. It’s also when we begin to see the change in color schemes on adult aquatic insects.

Aquatic insect adults are not only great sources of food for fish but also for birds. As a matter of fact, when you begin to see large numbers of swallows gather above the water and swooping down to the surface, it’s a sign for you to get ready because the hatch is beginning. Once the bugs have safely made it off the water, nature helps take care of them with appropriate camouflage to blend in with streamside trees and vegetation.

In the winter and early spring, most of your aquatic insect adults are black, grey, or some other dark color to better blend in with the dark, bare branches around the water. As we get later into spring and things begin to bloom, you begin to see more light- colored insects, such as tan and yellow. By the time summer rolls around, almost all of the adult insects are brighter yellows and greens to blend in with the abundant vegetation. And in the fall, you see more bugs with reds and oranges. There are of course plenty of exceptions to this but it’s a good guideline to follow with fly selection if you don’t know exactly what’s hatching.

So, April is a transitional month for color. Early in the month, we’re seeing the tail end of some of the darker bugs like Quill Gordons and Blue Quills, and by the end of the month we’re starting to see yellow bugs like Sulphurs and Little Yellow Sallies.

Egg Laying Imitation

Most of the hatches in the early part of the month are sparse and can be covered with generic flies like a Parachute Adams. The first hatch of significance in April is the Little Yellow Sally stonefly. It is one of the most prolific hatches in the Southern Appalachian Mountains, beginning usually around the third week of April and lasting well into July.

Unlike mayflies and caddisflies, stoneflies do not hatch in the water. Rather, the nymph will crawl out of the water onto a rock before hatching. Pay attention when you are on the water, and you’ll probably notice empty stonefly cases on exposed stream rocks. This means that the adult stonefly is not nearly as important to the fly fisherman because the adults are not nearly as available to the trout. We focus more on imitating stonefly nymphs, and for dry flies, focus more on the adult when it returns to the stream to lay eggs. You’ll notice that many of the adult Little Yellow Sally imitations are tied with a red butt for that very reason – to imitate the egg layer.

Little Yellow Sally Nymph

Stoneflies are often large bugs but that isn’t the case with the Little Yellow Sally, as suggested by the name. These are commonly found in size #16 and are typically a very bright yellow, and sometimes chartreuse. They tend to hatch sporadically through the day and return to the water in the evening to lay eggs. Typically, the later in the hatch it is, the later in the day they will return to the water. So, in April, you may see them dive bombing the water to lay eggs in the early evening, while in late June, that’s probably not going to happen until almost dark.

Neversink Caddis

There are a number of good imitations for the adult Yellow Sally. A yellow Neversink Caddis is one of my favorite “searching patterns.” For the nymph, you’ll want something tan to yellow in color. A small Tellico nymph or even a Hare’s Ear nymph should do the trick. And again, if you’re fishing when they’re laying eggs, something with a red butt can be very effective. Just plan to stay out late!

What Trout Eat – A Quick Glance at Aquatic Insects

When many people think of fishing with flies, images of more familiar insects such as houseflies and mosquitoes are typically conjured. While some of these familiar terrestrial insects like ants, beetles, and hoppers are a source of food for trout, especially in the summer, it is aquatic insects that are most abundant to fish throughout the year and what most artificial flies are intended to resemble.

There are a number of aquatic insects in streams and rivers with mayflies, caddisflies, stoneflies, and midges being the most common. They are defined as aquatic because most of their life is spent in various stages in or on the water. The four groups listed above vary respectively in their life cycles, but are similar in that they begin in one form under the water, emerge and transform to another stage, and ultimately return to the water to lay eggs and start the process again. Let’s use a mayfly as an example.

Mayfly Adult

First of all, the term mayfly is as general as the term flower. Just as there are many different flowers such as roses, daisies, and tulips, there are also many different mayflies such as Blue Wing Olives, Quill Gordons, and Sulfurs. And just as certain flowers bloom at specific, somewhat predictable times of the year, certain mayflies hatch at specific, somewhat predictable times of the year. Around here for example, you’ll usually see Quill Gordons in mid March, Sulfurs in May, etc.

The mayfly hatch that you hear about is technically the second time they hatch. A mayfly will first hatch underwater from a tiny egg into a nymph. The nymph is the juvenile stage of a mayfly’s life and it takes place entirely underwater. As a nymph, the mayfly has a very flat, streamline profile and typically lives beneath rocks on the stream bottom where it feeds on algae and such.

Mayfly Nymph

A typical mayfly nymph will live for about a year in this stage until it reaches maturity. At that time, the nymph will emerge to the surface of the water, a shuck splits open, and an adult mayfly (often called a dun) crawls out. The adult will be on the surface anywhere from seconds to minutes while it dries its newly formed wings before flying off to nearby vegetation.

With no mouthparts in this stage, the adult will usually not live for much more than a day so its sole purpose is to mate. After this occurs, the females will return to the water to lay their eggs until they finally lay spent on the water. So a mayfly’s only role in nature seems to be to feed trout.

But it’s not just trout that eat aquatic insects.  Birds probably get the lion’s share and most aquatic insects are naturally camouflaged with this in mind.  Understanding this can give you a leg up when it comes to fly selection, even when you don’t know what’s hatching.

In the very early and very late seasons when there is no foliage on stream side trees, aquatic insects need to blend in with the actual branches.  Consequently, most everything that hatches during that timeframe will be dark in color (Gray, black, etc.).  In the late spring and summer when foliage is full and vegetation is thick, most everything that hatches will be lighter in color (yellows, greens, etc.).  And in the fall – you guessed it – most of the bugs that hatch will be drab, rusty colors.

Flies: Zebra Midge

Black Zebra Midge

This is one of those flies that when you show it to an inexperienced angler (and many experienced ones too), the reaction will often be, “What size fish can you catch on that?!?” Whatever size fish is feeding on it. While there is sometimes a little truth to the big fly, big fish theory, fish are going to feed most on the most available food source.

In nearly every tailwater in the world, and certainly in every East Tennessee tailwater, midges are by far the most available food source. They are available to fish nearly 24 hours a day, 365 days a year. And while they may be small, they are abundant and big fish will eat them because they’re such an easy and available meal. More often than not, the first fly I tie on when fishing any tailwater, is some sort of midge.

Big fish on a small fly

In freestone streams like you find in the Smokies, we don’t fish midges as much because they’re not as prolific and they are often outnumbered by a variety of mayflies, caddis flies, and stoneflies. So it’s one of those weird ironies that we go to the mountains and fish larger flies for smaller fish and in the tailwaters, we fish smaller flies for larger fish! But they do have seasonal importance in the mountains. They are far more abundant in the late fall and winter than any other time of year.

Midges do hatch into adults but the larval stage is of the most significance to the fly fisherman. You will regularly see trout in the Clinch River tailwater surface feeding on adult midges. However, my experience has been that for every one hit you can get on a topwater midge imitation, you can get about twenty on a nymph. And for me, the number one nymph imitation for a midge is the Zebra Midge.

They can be REALLY small

Midges are rarely bigger than a size #18 and can get a whole lot smaller. I usually fish a size #18 Zebra Midge but will and have gone as small as a #24. You can go as small as you’d like but for me, if catching trout necessitates fishing size #28 flies… It’s time to go to the bar! The smaller the fly, the smaller the tippet you need. And at 45 years of age, I’ve come to the conclusion that trying to thread a #28 hook with 9X tippet and then land a 20”+ fish on that tiny hook and 9X tippet ceases to be fun. Most of the time, a #18 hook on 6X tippet is adequate.

Midges come in a variety of colors and that can vary on a daily basis. I mostly tie Zebra Midges in red, brown, grey, olive, and black. I fish black more than any color and in the mountains, almost exclusively – maybe olive. I typically tie them with a tungsten bead to get them down quickly but like to have a few un-weighted ones on hand to fish in the film.

This fly is as simple as it gets – just a bead, thread, and wire, but is incredibly effective and a must have in any trout fly selection. Try it!
