If you’ve done much fishing in the Smoky Mountains, you have
likely fished with this fly at one time or another. It is definitely a staple
in my fly collection. The main reason is that it provides the three quantities
that you want in a Smoky Mountain dry fly: It floats well, it’s easy to see,
and it catches fish!
Many like to point out that this fly will sink. Of course it will! I don’t know of a dry fly that won’t! But it does float extremely well, and the name “Neversink” doesn’t refer to its buoyancy anyway. Instead, it refers to the Neversink River in New York. Beyond that, the origin and history of this fly are cloudy at best.
The segmented pattern to the far left, captioned (perhaps inaccurately) “Original Neversink,” is claimed to be the original version of this fly, though I didn’t find much evidence to back that up. Additionally, I couldn’t find any information on who originated that pattern. The one next to it is a Neversink Caddis pattern originated by fly tyer, Jason Yeager. However, I couldn’t find anything that led me to believe it is the original. If there are any fly historians reading this, please let me know.
In any case, the pattern pictured at the top of the page is the version that I tie and fish, and it’s the one you’re likely to find in most fly shops. While I tie them in a variety of colors, yellow, tan, orange and chartreuse are among my favorites. I especially like the yellow version as it does a great job passing for the prolific Little Yellow Stonefly in the Smokies. As a matter of fact, there are a lot of yellow bugs that hatch in the Smokies from mid April through early October. Fishing with a yellow dry fly pattern of any kind is a pretty good bet during that timeframe.
While it is an effective representation for a caddis and some stoneflies, I tend to think of it as just a good, generic attractor pattern. And because of its better than average buoyancy and visibility, it makes a great top fly in a dry/dropper rig.
Hook: TMC 100 or equivalent, #16-#12 Thread: 8/0 yellow (or to match foam color) Body: 2mm yellow foam (or other color of your choice) Wing: Natural or bleached elk hair (bleached offers a little better visibility) Hackle: One brown and one grizzly rooster
Hendricksons have long been a favorite springtime hatch for Eastern fly fishermen. In the Smokies, they typically follow the Quill Gordon and Blue Quill hatches by two or three weeks. Most years, that means we don’t see Hendricksons until mid to late April. Because a warm stretch of weather in February triggered an early Quill Gordon hatch, things are a little out of whack and we are beginning to see Hendricksons now. I expect them to be around until about mid April.
Like many hatches in the Smokies, Hendricksons rarely come
off in enormous, widespread numbers. But in the right place at the right time,
you can find enough of these bugs to inspire some steady rises from trout. And
while generic, attractor fly patterns will get you through most situations,
having a fly that more closely matches what the fish are seeing never hurts!
Hendricksons hatch sporadically throughout the day in the
Smokies but tend to be most active in sunny areas during the warmest part of
the day. Most days this time of year, that means in the 2pm – 5pm range. They
inhabit all types of water but I tend to see emergence occurring most in slow
to medium currents.
The nymphs are not particularly good swimmers and they have an unusually robust profile. This combination of traits makes them very popular with the trout. Their color varies from reddish tan to dark, reddish brown. Tan and olive Hare’s Ear Nymphs work well for imitations. Whitlock’s Red Fox Squirrel Nymph is another great pattern during this hatch. Pheasant Tail Nymphs provide a nice color match but are pretty slender compared to the beefy naturals. In any case, they range in hook size from #14-12.
The adults also vary a bit in color. Much of that depends on the gender of the bug. The males tend to be darker, varying from grayish olive to grayish brown. However, the females are often a little lighter, sometimes taking on a tan or even pinkish hue.
While there are certainly numerous fly patterns specifically designed to imitate all of the variations of a Hendrickson, you can do pretty well with generic patterns as well. A Parachute Hare’s Ear works well, particularly when you’re seeing more of the lighter colored adults. And there’s always the Parachute Adams, especially when you’re seeing the darker variations. Like the nymphs, you’ll best match the naturals in sizes #14 – 12.
Finally, trout love taking the emerging insects during this hatch, so a wet fly can be an excellent choice. One of my favorites is the Early Season Wet Fly. I often fish it in tandem with another fly. Try it as the top fly of a nymphing rig with a Hare’s Ear or Red Fox Squirrel nymph down below. Or tie it as a dropper off the back of your dry fly of choice.
One of the worst things you can do to a dry fly is catch a fish on it! They slime it and submerge it and swim it around… Just in general, keeping a dry fly floating better and longer seems to be an ongoing quest for many fly tyers and fishers.
There are a number of factors that can go into how well and how long a dry fly continues to float high. Certainly the materials from which the fly is tied will play a big role, as will the skill of the angler. The more you allow your fly to drag across currents, rather than drift on them, the more waterlogged your fly will become. Where you are fishing will make a difference, too. It’s easier to keep a fly floating high in big, open rivers where false casting is an option than it is in a small, tight mountain stream. In any case, an endless number of products exist for this task. We lump them all into the category of “floatants.”
As with many products in the fly fishing world, if you ask ten different anglers which one is the best, it’s entirely possible that you will get ten different answers. Sometimes those answers will come in the form of a specific brand of floatant. Others will come in the form of a specific style. When it comes to brand, I believe that is a matter of personal preference and you’ll just have to try a few different ones to see if one in particular earns your loyalty. But when it comes to different styles of floatant, the specific task at hand may determine which will be best. In fact, you may want to have more than one style of floatant to perform different tasks. Listed below are a few different common styles of floatant and a description of how and when they might best be applied.
While many anglers use them in different ways, liquid floatants are probably most useful before you ever get to the stream. Whether dry flies that you tie yourself or buy from a shop, you can use a liquid style floatant to “pre-treat” new flies in much the same way as you might “Scotchgard” your sofa. Exact application may vary. Read the recommendations for the specific brand you purchase. You typically soak the flies in the liquid for five minutes or so and dry them overnight. In theory, after application of the product, water will better bead and roll of the fly material rather than absorb into it.
Gel floatants are probably the most common and popular style of floatant. They come in a small, very portable bottle and, like the liquid floatants, are designed to be a pre-treatment to an already dry fly. The big difference is gel floatants are designed to be used streamside, immediately before fishing the fly.
It is important that you don’t “over apply” the gel. Rub a small amount into the fly and any remove any excess. Gels are also frequently mis-applied – after a fly has already become waterlogged. If a fly is already saturated, applying a gel floatant will essentially trap moisture into the fly and make it worse.
Also normally applied while the fly is still dry, spray floatants are basically just a variation on a gel floatant. Spray floatants come in a bottle with a pump top and apply much like you would spray an eyeglass cleaner. They are not as messy as the gel but are sometimes more challenging to completey coat the fly.
These are basically just a thicker version of a gel floatant. They really create a mess on smaller dry flies. Use paste for larger dries like hoppers and stoneflies. A lot of people prefer a paste floatant to apply to yarn strike indicators or even on a leader to keep it floating better.
Use these less as a pre-treatment and more as a means to revive a saturated fly. As mentioned above, when a dry fly becomes oversaturated and begins to sink, applying a gel or spray can often make it worse by trapping moisture in. Powder floatants absorb and remove that moisture from a fly.
Typically they will come in a bottle with a wide, flip-top lid. Keep the fly, on the tippet, put it in the bottle and close the lid. Shake the bottle a few times to remove moisture from the fly.
At this point, there is a lot of debate on whether to re-apply a gel or spray type floatant. You’ll just have to find what works best for you. I usually don’t re-apply another floatant unless I’m using a synthetic (like foam) dry fly.
Brush floatants are essentially another version of a powder floatant. Rather than shaking the fly inside the bottle, use a small brush to apply the powder to the fly. Again, it’s personal preference but with brush floatants, expect a little frustration on windy days!
There are countless styles and floatants on the market today and all have their place. And unlike the homemade lighter fluid and paraffin concoctions of days gone by, they are typically odorless and environmentally friendly. You just need to find a system that suits your needs.
Personally, I carry a gel floatant for pre-treating dry flies and a “shake style” powder for reviving them and get by just fine. But I offer the disclaimer that I often offer in these newsletter articles… This is just one man’s opinion!
I was shocked when I realized that I had never included an article about the Parachute Adams in this newsletter. Not only is it one of the best dry flies in the Smoky Mountains, it is arguably the best dry fly for trout in the world. It doesn’t imitate anything in particular but just has a buggy look. Therefore, it serves as a great “generic” mayfly imitation. In a pinch, it could also pass for a number of caddis and midges.
It is derived from the original Adams dry fly. A parachute pattern is merely a method of tying a dry fly. While traditional mayfly patterns had two upright and divided wings, with a hackle wound around the hook vertically; a parachute pattern has a single post with the hackle wound horizontally around that post. Because the post is typically white or some other bright color like pink or orange, the angler can better see the fly on the water. Additionally, with a hackle wound horizontally around the post, the fly rides flatter on the water with a more realistic profile.
The original fly has been around for nearly 100 years. In 1922, Leonard Halladay, a Michigan fly tyer conceived the Adams as a general mayfly imitation. It was first fished by an Ohio attorney and friend of Halladay, Charles F. Adams on the Boardman River near Traverse City, Michigan. Charles Adams reported his success with the fly to Halladay who decided to name the fly after his friend. While it is unclear exactly when the Adams got the “parachute treatment,” parachute style flies began gaining popularity in the U.S. in 1971 when Swisher and Richards published the book, Selective Trout, and advocated the advantage of dry flies that rode flush on the water. One would assume that the parachute version of the Adams was born somewhere in that timeframe.
Since then, it has seen numerous variations in the body color, post material, post color and more. While many of these variations have been highly successful, it’s still tough to beat the traditional pattern. Below is the recipe for the traditional version.
Hook: TMC 100 (or equivalent) sizes #10 – #26
Thread: 8/0 black
Tail: Even mix of brown and grizzly hackle fibers
Body: Natural muskrat fur (or and modern dry fly dubbing in Adams Grey)
Post: White calf hair (synthetics such as floating poly yarn also work well)
Hackle: One grizzly and one brown rooster hackle, sized to match hook
Most people like fishing dry flies because they can see the fish take it. But fishing dry flies in the Smokies can be a challenge, especially in pocket water. Besides being difficult to keep afloat, they can be difficult to see in fast water. But the good thing is trout aren’t often selective in this kind of water. Therefore, you’re choice of dry flies usually doesn’t have to be so “precise.”
When it comes to fishing dry flies in the Smokies, I am typically looking for two primary things in a pattern. It needs to be visible and it needs to be buoyant. Beyond that I can begin focusing on a few more details like color and size.
In general, trout in the Smokies don’t see heavy hatches of individual insects. Sure, there are exceptions. But they mostly see small quantities of a lot of different insects. So, if you can present the fly naturally and without spooking fish, most any all-purpose, “prospecting” fly pattern will do the trick. As mentioned above, if you can get a little more precise with size and color, your pattern will be that much more effective.
Matching size will require more observation of bugs on the water or simply having general knowledge of what should be hatching. The same two things can help with matching color. Having a broad knowledge of how seasons impact color will also help. With some exceptions, aquatic insects tend to blend in with their surroundings. So, in winter months when trees are bare, most of what hatches is dark because the bugs need to blend in with the darker branches. As foliage comes in, most of what hatches is brighter. Because the bugs need to blend in with the leaves. It’s nature taking care of itself.
The Stimulator is a long time favorite fly pattern of Smoky Mountain anglers for all of the above reasons. Its buoyancy and light colored wing not only make it easy to see, but make it a perfect “indicator fly” when fishing a dropper. And if you mix and match sizes and colors, you could nearly fish a Stimulator 12 months out of the year!
The Stimulator was long thought to be the invention of well-known West Coast angler and fly shop owner, Randall Kaufmann. While Kaufmann is responsible for the modifications that made the fly most of us know today, the fly’s true originator is thought to be Paul Slattery, who tied a stonefly pattern called the Fluttering Stonefly to fish on the Musconetcong River in central New Jersey. This was in the early 1980’s and he soon renamed the fly after a New York City punk-rock band called The Stimulators.
In any case, the fly seems to have been created to imitate an adult stonefly, but it is also a good suggestion of a caddis and sometimes even a hopper. I most often fish it in yellow and in sizes #16 – 8. I think the smaller size makes a great imitation for the prolific Little Yellow Sally Stoneflies. The larger sizes are good representations of the larger golden stones. They tend to hatch on summer evenings in the mountains. In the fall, I often fish a #10 Stimulator in orange to imitate the large ginger caddis.
Whether it imitates anything or not, it catches fish and it floats well in heavier pocket water found throughout the mountains. As one of the most popular dry flies of all time, it is available in most every fly shop in the country.
Hatches can sometimes be maddening. Fish feed aggressively and routinely on the surface. But sometimes, every single one of them ignores your fly. There are a number of reasons this can happen. It may be because of the style of fly you’re using.
In the Smokies, we are mainly fishing faster, choppier water and often choose bushier, more heavily hackled dry fly patterns because they float well. In that kind of water, trout don’t get much time to study the fly and their view tends to be distorted by those choppy currents, so the bushier flies tend to do the trick. Even when fishing pools in the Smokies, you usually have a defined feeding channel that will have at least a little chop to it. In those situations, a parachute style fly pattern is usally adequate to provide a slightly more realistic profile.
But in flatter water like you commonly see on tailwaters like the Clinch, particularly weeks into a heavy hatch, an even more realistic profile is necessary. Trout routinely refuse parachute style flies and probably wouldn’t even consider a vertically hackled Catskill style dry fly.
This problem isn’t new to fly fishers. In the 1930’s, Fran Betters developed the Haystack to fool trout in slow moving spring creeks. It consisted of a deer hair wing and tail and no hackle, allowing for a lower riding fly with a much more realistic profile. Al Caucci and Ed Natasi introduced the Comparadun, a variation of the Haystack, in their 1972 book, Comparahatch. The pattern is essentially the same but they were able to use more modern microfibbets. They provide a longer, slimmer, more durable split tail that aids in floatation.
In the mid 1980’s, Craig Matthews and John Juracek took the Comparadun a step further and replaced the split microfibbet tails with a piece of antron or zelon. It essentially turned the fly into an emerger with the antron or zelon “tail” suggesting the trailing shuck of an emerging mayfly. Of course, in any of the patterns described above, the body, wing, and tail/shuck colors can be altered to imitate different insects.
I routinely fish the split tail and the trailing shuck versions, usually during a sulphur or BWO hatch. And again, I am usually fishing them on the Clinch or possibly in a slow pool in the mountains. They just don’t float well enough to fish them in faster riffles and pocket water. But on a slow glide on the Clinch, they can be deadly!
Hook: TMC 100 (or equivalent) #16-18
Thread: 8/0 pale yellow
Tail: Light dun microfibbets ( or replace microfibbets with small tuft of brown antron for trailing shuck version)
Body: Pale yellow dry fly dubbing
Wing: Coasatal deer hair
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, but having a few of a basic pattern isn’t a bad idea.
Because March Browns are big, they tend to get a little more attention from trout. They are 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, because they need to blend in with the bare trees and vegetation. But March Browns usually have a light, reddish brown body with handsomely mottled wings of brown, tan and even yellow hues. Despite 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.
The nymphs are probably the most important stage for Smoky Mountain fishermen. Because they have flat clingy bodies with muscular legs, they are very strong crawlers. But 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. So, a Hare’s Ear Nymph or Pheasant Tail Nymph are both 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.

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. This is probably because it was the first really BIG hatch I ever fished. It’s not quite as epic as it was 20-30 years ago. I won’t get into the reasons why. But it is most definitely still a hatch worth making time for.
The hatch usually starts 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.
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. This makes for a fast and furious end to the day for those willing to fish through supper.

With thousands of patterns available, choosing the perfect fly can prove to be a daunting task for any angler, particularly the beginner. However, unless you’re in a situation where trout are selectively feeding on a specific insect that is abundantly hatching, an assortment of well presented attractor patterns will be all you need to catch fish. Every fisherman has a list of favorite flies and over time you will find particular ones with which you are very confident. And that’s really the bottom line. If you have confidence in a fly, you will fish it better and ultimately have more success.
Below is a compilation of flies that seem to work everywhere and are on most fly angler’s list of favorites – a perfect place start your fly selection! Whether you call a fly shop in Tennessee, Montana, or New Zealand and ask for recommended flies for the area, somewhere on that list you will likely find most if not all of these patterns. These flies are also available as a packaged selection in the Fightmaster Fly Fishing online store.
1) Parachute Adams: This is an absolute favorite trout fly. It doesn’t look exactly like anything but looks a lot like a lot of things! Carry them in sizes #12-#18 with the smaller versions being ideal for slow water and more finicky trout and the larger being best suited for choppier water where visibility is more important. The traditional grey body is preferred, but a yellow body also does well in the Smokies.
2) Elk Caddis: Another great dry fly, carry this one in sizes #12-#18 and with body colors of olive, tan, and yellow. The down wing on this pattern gives it a little different profile than the Adams and the combination of elk hair and hackle make this fly float like a cork.
3) Griffith’s Gnat: This is a great general purpose small fly. Fished most often in sizes #16-#20, it is a great imitation for adult midges, small mayflies or caddis, and even ants. Many of the most finicky, rising trout I catch are on a Griffith’s Gnat.
4) Pheasant Tail: An incredibly universal pattern that looks like almost every nymph you’ll find under a submerged rock. You’ll probably fish the bead head version the most. But, the traditional version provides a more realistic pattern that can more easily be fished in different levels of the water column. Carry both varieties in sizes #12-#18.
5) Hare’s Ear: For the same reasons as the Pheasant Tail, carry bead head and traditional versions of this fly, and in the same sizes. The big difference in the two nymphs is the Hare’s Ear provides an option for a lighter colored nymph and it is a little “buggier” than the Pheasant Tail, providing more movement. Most tend to favor the traditional tan body color but an olive body is also very effective and versatile.
6) Prince Nymph: This fly gives you that all important peacock herl factor which trout seem to dig. The white colored goose biots on the back also seems to grab the attention of fish. I’m not sure if anyone knows exactly what it’s supposed to imitate but the bottom line is it works! A Zug Bug is a close cousin to the Prince and would likely make many anglers’ favorite fly list. The two are similar and you can’t go wrong with either. Carry them in sizes #8-#16.
7) Zebra Midge: This fly will cover most of your small nymph needs. It is a simple pattern but extremely effective. Best fished in tailwaters and slow pools in mountain streams, carry it in sizes #18-#22. Most tend to prefer the tungsten bead head versions with black, red, or olive bodies.
8) Wooly Bugger: While there are numerous great streamers out there, only one made this list as a must have, probably because of its incredible versatility. The Wooly Bugger, carried in a variety of colors, can facilitate almost any streamer need. Carry them in black, olive, tan, and white in sizes #4-#10 and you have an effective imitation for small baitfish, leeches, and crayfish. In a pinch, you can even dead drift a Wooly Bugger as a pretty effective imitation for a stonefly nymph or hellgramite. Whether you choose bead or no bead, flash or no flash, you have a fly capable of catching most any kind of fish in any kind of water.

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, get ready. 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. They can 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.
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. The adults aren’t as available to the trout. You should focus more on imitating stonefly nymphs. For dry flies, focus more on the stage when it returns to the stream to lay eggs. You’ll notice that many of the adult Sally imitations are tied with a red butt for that very reason. It imitates the egg laying stage.
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. In April, you may see them dive bombing the water to lay eggs in the early evening. In late June, that’s probably not going to happen until almost dark.
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!
