Rob’s Hellbender Nymph

Since we’re talking about big browns this month, I thought it only fitting to feature one of my favorite flies for big brown trout. While I have caught a number of big browns on small flies over the years, most of the big guys in the mountains have come on larger stonefly nymphs. This is a little bit misleading as most of the large browns I’ve caught in the Smokies I spotted before I fished for them. And when I spot a big brown trout, I almost always tie some sort of stonefly nymph imitation to my line. Who is to say I wouldn’t have caught those same fish on a #20 Zebra Midge had I chosen that fly?

I’ve always said that fly selection is 45% scientific, 45% experience, and 10% dumb luck. The scientific aspect comes in when you choose a fly to specifically imitate something that the fish are known to be feeding on. For example, if you see sulfur mayflies hatching, you see fish feeding on them, and you choose a sulfur mayfly imitation, you’ve more or less made a scientific decision. If you go to the stream and tie on a Royal Wulff for no other reason than you’ve always done pretty well on a Royal Wulff, you’ve made your decision based on experience. And of course, if you choose to fish the purple and green fly for no other reason than it looks neat, you’re pretty much depending on dumb luck!

All three methods have been successful over the years but the first two are usually more reliable because you have something at least somewhat logical and reliable to base the decision on. Even when your logic may be incorrect, such as choosing a sulfur to imitate a perceived sulfur hatch when the fish are actually eating caddis, you tend to have more success because you have confidence in your fly. When you have confidence in your fly pattern, you tend to fish it longer and better.

My tendency to select a stonefly nymph when I fish to a big brown trout comes from scientific reasoning and experience. I’ve studied the aquatic entomology of the Smokies and know that there are a lot of stonefly nymphs in the streams. I also reason that a larger morsel of food, like a stonefly nymph, would be more enticing to a larger fish. And I’m also relying on experience – I’ve caught a lot of big brown trout on stonefly nymphs over the years.

Golden Stonefly Nymph

Some of my favorite “go-to” stonefly patterns over the years have been old standards like a Tellico Nymph, a Bitch Creek Nymph, and a Girdle Bug. I always liked the coloring of the Tellico because I thought it best represented a golden stone, which seems to be the most prolific big stonefly in most Smoky Mountain streams. I liked the flat, two-tone profile of the Bitch Creek Nymph. It seems to produce a nice rocking motion on the drift. And while the Bitch Creek Nymph does incorporate rubber legs in the design, the additional rubber legs on a Girdle Bug always seemed to give it a much more lifelike appearance.

So what did I do? I took what I thought were the best features from each of my favorite stonefly nymph patterns and blended them into one fly. The result is Rob’s Hellbender Nymph. It has the flat, elongated, two-tone profile of a Bitch Creek, the multiple rubber legs of a Girdle Bug, and a color similar to the Tellico.

I weight these flies with lead wire that is flattened to provide that rocking motion in the water. I not only tie them in different sizes, usually #10 – #4, but I tie them in different weights. To get down fast in deep, fast runs, I like a lot of weight, but I prefer a lightly weighted one when casting to a brown trout in the shallows.

For whatever reason, offering flies in different weights tends to be too confusing to customers at a fly shop so commercially tied patterns like this one are typically made available in one uniform weight. So the ones you find in a shop like Little River Outfitters are going to be lightly weighted so the fly can be fished in slower, shallower water. To get them down quickly in deeper, faster runs, just add the appropriate amount of split shot.

While I may choose something like a large streamer when searching for big browns, this fly has become my “go-to” for a large brown that I have spotted first. Of course, every situation is different and there will be countless circumstances that suggest otherwise. But next time you’re in the Smokies with a big brown in your sights, see what he thinks about this bug!

Flies: Red Fox Squirrel Nymph

Even with all the newfangled fly patterns and fly tying materials available today, I usually find myself sticking more with the old staples, or at least pretty similar variations. And I stick with them for one main reason: They work! Created by fly tying guru, Dave Whitlock in the 1960’s, this fly definitely falls under the “old staple” category.

As disappointing as this may be to some, the fly was not named for Redd Foxx of Sanford and Son – you big dummy! Rather, it got its name for the simple reason that it is tied mostly from the fur and hair of a red fox squirrel. It is considered an impressionistic fly, meaning that it is designed more to look alive or “buggy” more than imitating a specific food source. We also lump these sorts of flies in the categories of “attractors” or “generals.” Or Orvis likes to call them “prospecting flies.”

So really, it’s a pretty good fly to fish anytime in the Smokies, but I think it is at it’s best in the early spring. I attribute that to the abundance of Quill Gordon nymphs in the water at that time, as this impressionistic fly imitates that nymph as well as any other I’ve fished. I’ve had a lot of success with the traditional, light red version of this fly, but tie them in a few other colors as well. Different colors might better imitate other food sources in the water, but may also better imitate the color of Quill Gordon nymphs found in a specific river, or even a specific stretch of river.

Quill Gordon Nymph

It’s hard to say just how selective these trout can get and how important it is to match the color of the nymph, but I’ve personally found Quill Gordon nymphs in Little River that range from a light reddish color, to tan, to grey, to dark reddish brown, to olive. You can see that the Quill Gordon nymph in the picture has more of a dark reddish brown color. Though it’s probably more of a confidence thing, it seems that some years a certain color just works better than another.  I like to fish double nymph rigs with two different colored nymphs until I zero in on their preference.

In any case, these Quill Gordon nymphs are pretty robust, and the beefy body on the Red Fox Squirrel Nymph seems to suggest that better than, say, the slender profile of a Pheasant Tail Nymph. And the picked-out fur body and soft hackle provide a lot of subtle, life-like movement.

Hare’s Ear Nymph

A close cousin to the RFSN, is the Gold Ribbed Hare’s Ear Nymph. This is another one of those staple flies that is really simple to tie and can be found in most any fly shop.   I will sometimes fish these in a tan or olive color as an alternative to the RFSN or even in tandem in a two nymph rig.

In all cases, I’m usually fishing these flies in fairly large sizes – typically in the #14 – #10 range. As the season progresses, I’m more likely to fish them in smaller sizes and lighter colors. They can be purchased or tied in beadhead or non beadhead versions. The non beadhead will typically have lead wire wrapped around the hook under the materials. I personally like the look and profile of the beadless version better. But that’s just one man’s opinion. Try them both and tell me what you think!

Below is Dave Whitlock’s original recipe for the nymph.  I fish the beadhead version most, and I tend to substitute commercial dubbing for the mixes he describes below.

Flies: Quill Gordon Hatch

March is the month when trout fishing in the Smokies officially kicks off. Days are getting a little longer, temperatures are getting a little warmer and water temperatures are on the rise. It’s also the month when we begin to see our first good hatches of the year.

Aquatic insects from Early Black Stones to Blue Wing Olives to a variety of midges will hatch all winter, but trout rarely pay much attention to them as water temperatures are typically too cold for active feeding (read Understanding Water Temeratures for more info). But in March, that begins to change. And if you pay attention to water temperature, you just might catch one of the best hatches of the year.

Quill Gordons are fairly large mayflies, between a #14-10 hook size, that begin to hatch when the water temperature reaches 50-degrees for a significant part of the day, for a few days in a row. In unusually warm years, they’ve hatched as early as mid February. In particularly cool years, they may not hatch until April. But most years on the lower elevation streams in the Smokies, this occurs about the third week of March.

In any case, it’s a tricky hatch to catch and really just a tricky month to fish if you don’t live here where you can pick your days. Weather can change in the blink of an eye in March and one major cold front or one big, river blowing rain can make all the difference in your success. I’ve had some of my absolute best days in March and I’ve had some of my worst.

So, why even fool with it? Why not just wait until April when things are more stable? Because some of those “best days” were really, really good! The Quill Gordon hatch is not just worthwhile because of the number of bugs or the size of the bugs. It tends to happen at the exact same time wild mountain trout begin actively feeding. Many of these trout, including the large browns, have had very little to eat in the last 2-3 months and they tend to be a little less cautious. And when a size #12 Quill Gordon comes drifting down the lane, well, it’s pretty hard to resist!

Brown trout exceeding 20” don’t get caught very often in the Smokies, period. Even fewer are caught on dry flies. I’ve been fortunate to catch a fair number of large browns on dry flies in the Smokies, and probably 99% of them have come during the Quill Gordon hatch. Though it’s certainly a gamble, THAT is why it’s worth coming in March!

The good thing about the hatch is once it starts, it usually doesn’t stop. So, if the hatch gets started on say, 3/21, they’ll keep hatching every day even if you get a significant cold front on 3/25. While such a cold front may not impact the hatch, it still might impact the way the trout feed, and they may be more reluctant to come to the surface. What many people forget, is that for all the bug activity on the surface during a hatch, there is just as much, if not more, activity under the surface with nymphs preparing to hatch. Drifting a greyish olive nymph below the surface can also be very productive during this hatch, especially in colder water

Most years the hatch lasts 2-3 weeks and it is usually at its best during the warmest part of the day. In March, that’s typically about 11am to 4pm so rearranging your lunch plans is not a bad idea.

The best place to be during the hatch is in a larger pool near the head and middle of the run. Unlike most other instances fishing the Smokies, this is a time when you may need a little more distance on your cast and your mending skills will be put to the test. The fish may be more aggressive but they still won’t tolerate a bad drift!

Skills: Fishing High Water

The Smoky Mountains are known for receiving large amounts of rain in a season and when it comes in bunches, the result can be swollen, rough, intimidating, and dangerous streams and rivers. Good and bad things occur when the water rises in mountain streams. On the down side, the streams become much more dangerous and sometimes impossible to wade. The faster current also makes it more difficult to control your drift. On the up side, a lot of food gets churned up in the stream, and that factor, combined with a level of comfort and security in stained water, often results in more reckless feeding by some of the bigger trout on the block. There are brown trout exceeding 20” in many mountain streams that don’t get caught often, but when they do, it’s usually when the water is up and off color.

The stream is going to look completely different under these conditions and it will help if you have intimate familiarity with the stream under normal flows. Regardless of how well you know the water, always use extreme caution under these conditions and don’t try any heroic stream crossings. One wrong step can quickly get you in big trouble! In fact, it’s not a bad idea to wear a life vest when fishing under these conditions. Better safe than sorry!

Forget about finesse. You’re not going to coax rainbows to #16 dry flies with delicate casts. Bring a long rod for a heavier line – maybe a 9’ 6 weight – and plan on chucking large, heavy nymphs with a rosary of split shot and no strike indicator. Casting is going to simply involve one flip behind you, wait for the tug on the rod tip, and chuck it forward with an open loop. Long casts are not necessary and will be less effective.

Instead, wade the edges and look for slower seams on the edge of fast currents and eddies behind rocks. Position yourself as close to the feeding zone as you safely can and use the length of the rod to reach and hold your flies in position. Keep the rod tip up and try to keep as much of the fly line off the water as possible, allowing for a much slower, more controlled drift. Follow the flies with the rod tip as they drift through the feeding lane and keep an eye on the fly line between the rod tip and water. You may feel a strike since you’re working with such a short line but most likely you’ll determine the strike when you see the fly line pull down or hesitate. If anything suspicious like this occurs, set the hook! With practice you’ll soon be able to differentiate between fish and rocks.

Don’t expect to catch large quantities of fish under these circumstances. It will be tough fishing to say the least. But if you stick with it, the rewards can be enormous!

Flies: Isonychias

The mayfly with the funny name is one worth knowing when it comes to fishing in the late summer and early fall. Actually, all mayflies have funny names, but most, over the years, have become known by some common name such as Light Cahill, Sulfur, March Brown, or Quill Gordon. But the Isonychia still proudly boasts its Latin name. Sure, there are those who might refer to them as Mahogany Duns, Slate Drakes, or even Leadwing Coachman, but none of those names ever stuck.

Isonychia Nymph

Probably the main reason is that those common names refer more to this insect in its adult stage, but to the trout (and trout fisherman), the nymph is by far the most important stage of this insect’s life. Isonychias, or Iso’s as some call them, don’t behave like most other mayflies when they hatch. Most mayflies will emerge to the surface and hatch in the water near the surface film. After hatching, they are often on the surface for a small amount of time, allowing their wings to dry before they fly off. This leaves most mayfly adults vulnerable to hungry trout and is the stage of the lifecycle that many dry flies represent.

But Iso’s behave more like a stonefly in that the nymphs swim to rocks or woody debris and hatch out of the water, with the trout never getting a shot at the adult until it later returns to lay eggs. Take a closer look at exposed rocks in or around the stream this time of year and you’ll likely see some of their empty shucks.

In the Smokies, they typically hatch from August through October with peak emergence in September. If you want to try your luck imitating them with dry flies, try a dark bodied parachute in size #14-12. The body color will typically be anything from a deep mahogany to dark grey or even black. A good ol’ Parachute Adams is probably as effective as anything. When they return to the water to lay eggs (known as the spinner stage), their body color is more orange or rusty.

George Nymph

However, as mentioned above, the nymph is what you should be most concerned with. Also in sizes #14-12, the nymph is slender with a dark brown to black body with a very distinct white stripe down the back. You will sometimes find specific Isonychia nymph patterns but they are also imitated well with such common patterns as Prince nymphs or Zug Bugs. The late Eddy George was a well-known and highly respected fisherman and fly tyer in this area. He is probably best known for the George Nymph, a fly that I regularly tie and fish in the Smokies. Many people speculated what this fly might represent but with its slender, dark body and white poly-yarn back, it’s incredibly effective during Isonychia time!

Dark soft-hackled wet flies are very productive, too, as Isonychias are active swimmers and tend to be most active in the mornings and evenings. Any time of day is a good time to drop one of the above fly patterns off a dry fly. Early and late in the day, try fishing with one or a pair of these nymphs and vary your typical dead-drift presentation to offer the occasional twitch or even swing. Check out the “Active Nymphing” article in this newsletter for more on that presentation.

Flies: Green Weenie

In June, hatches start to thin out. We still see a fair number of Yellow Sallies and a smattering of caddis and mayflies, but the heavier, attention getting hatches of spring have mostly come to an end. But when summer eases its way into the mountains, trout turn their attention to terrestrials, and so should you. We’ll talk about several varieties of terrestrials over the coming months but we’ll start with the granddaddy of all mountain terrestrials: the Green Weenie.

If you’ve spent much time around Smoky Mountain fly shops or researched recommended fly patterns for the area, you’ve no doubt run across this fly. Chances are you’ve fished one at some point. While incredibly simplistic, this is one of the most popular and most productive fly patterns in the Smoky Mountains. My good friend Brian Courtney ties this fly for Little River Outfitters in Townsend and to date, has tied them 25,000!

Inchworm
Caddis Larva

There is a little bit of debate about what the fly actually imitates. Many claim it imitates a caddis pupa. Most believe it imitates a green inchworm. Since I am including it in a conversation about terrestrials (land based insects), you can guess which side of the debate I fall. There a lot of those little green inchworms that end up in the water and trout love them! But the truth is, many caddis pupae look very similar to green inchworms, and the Green Weenie is a pretty effective imitation for both. However, one of the reasons I tend to put it more in the terrestrial family is that it works best in terrestrial season. While you can certainly catch fish on it other times of the year, it always seems to be at its best from mid May through early October.

The Green Weenie is different than most terrestrials like hoppers, beetles, and ants in that you typically fish it like a nymph rather than on the surface. There are other floating fly patterns intended to imitate inchworms but I don’t find them to be nearly as effective. Inchworms are poor swimmers and once they hit the water, it’s not long before they are submerged. So mostly I tie my Green Weenies to sink, and fish them on a dead drift. But I do tie a number of variations for different water types and situations.

Beadhead Green Weenie

When the stream is running fuller or when I’m fishing deeper pools and runs, I tend to fish more heavily weighted patterns. These are sometimes tied with a bead head or with several turns of lead wire under the body and fished under an indicator or with straight-line tactics. In these situations, I often fish the Green Weenie in tandem with a second fly. One of my favorite combinations is a Green Weenie for the top nymph and a smaller, more subdued nymph like a Pheasant Tail about 15” below it. Trout often take the Green Weenie but I believe just as often, its bright color gets attention and the trout take the more subdued fly. When nymphing shallower runs or pockets, I’ll often replaced the weighted trailer nymph with an un-weighted nymph or soft hackle pattern.

Another favorite technique for fishing shallow runs and pockets is to put the Green Weenie about 15” off the back of a dry fly. In these instances, I prefer an un-weighted Green Weenie. The weight of the hook is enough to get it down in this kind of water and the dry fly floats better and longer in choppy currents without the extra weight. I do sometimes like to add a glass bead to the fly for these occasions.

Barbie Bug

I most often fish this fly in a bright lime green to chartreuse color but also in more drab olive and insect green shades. Others have reported a lot of success with white, beige, and tan colors. And for whatever reason, pink seems to work well. You will sometimes see the pink version referred to as a Barbie Bug. Regardless of color, I tend to fish them in sizes #10 through #14. The smaller sizes, sometimes down to a #16, are reserved mostly late summer and early fall when the water is lower.
