On the Fly – Double Surgeon’s Knot

One thing that you will certainly do plenty of when fly fishing is add tippet. As you change flies through the day, you shorten your tippet. When you hang up in trees and have to break the line, you shorten your tippet. There are a few knots that you can use for this but the Surgeon’s Knot is one of the easiest and strongest. Here’s how to do it:

“On the Fly” is a feature in my monthly newsletter offering quick fly fishing tips to make your life on the water a little easier…

Adjusting Weight When Nymphing

Split Shot

Warning! This article contains terrible illustrations!

Several years ago, I was fishing a stream in the Smokies that I probably know better than any other. It was an early spring day and the water temperature was marginal at around 50-degrees, and the water level was a little high because of recent rainfall. I’d been fishing for two hours and hadn’t even had a strike. I knew it wasn’t a dry fly kind of day. Therefore, I continued to switch nymph patterns, trying to find something that would fool one trout.

Eventually, I decided to stick with one fly pattern, a Pick Pocket, that I had a lot of faith in and to begin altering the way I fished it. Since it was an un-weighted wet fly, I already had one split shot about 8” above it. I began swinging the fly a little more, but the result was the same. Next, I added a second split shot and fished with a mix of swing and dead drift techniques. Nothing. Finally, I added a third split shot and hooked a fish on my second cast. I proceeded to catch another 30 fish or so over the next couple of hours.

I should have known better but we all seem to get too caught up in fly patterns and lose sight of other important factors like drift and depth. Well, I had been fishing good drifts all day, but these fish were hugging the bottom. My fly was not getting, or at least staying, down in their feeding zone.

Do you use split shot when you’re nymphing? There are definitely times when you need to. One of the best nymph fishermen I have ever fished with is Joe Humphreys. It is excruciating to watch him fish because every time he moves to a different spot, he adjusts the amount of weight on his line! But he often catches fish that others don’t because of those adjustments!

Being willing to add or remove split shot to your line is the first step. Knowing where and how to place those weights is the next. For instance, if you put three split shot right next to an already heavily weighted fly, you may have a hard time keeping it off the bottom. So, you have to figure a lot of things, like how heavy your fly is, how deep the water is and how fast the water is. Just the weight of the fly may be all you need to get the nymph near the bottom in slow water, but faster currents may move that fly all over the place. Extra weight can be used not only to get the fly deeper, but also to slow the drift and keep things where they should be.

Shot placement is tricky in places like the Smokies where depth and current speed can vary significantly, even in the same run or pocket. Short casts and good line control can significantly help combat this. Strategic split shot placement can also make a big difference.

Split Shot Placement
Split shot placed at the fly

The closer you put the additional weight to the fly, the more you’re going to put the fly on the bottom. As a result, you’ll probably hang up more. But if you put a concentrated amount of weight on a section of leader above the fly, that portion of leader will be what drifts deepest, and the fly will ride above it. The farther the split shot is above the fly, the farther off the bottom the fly will drift.

Of course, there are variables like how heavy the fly is and how much split shot you use. Sometimes you just have to play with it a little bit. When you get as good as Joe Humphreys, you can make those calculations in your head and adjust perfectly for each new spot you fish. Here are a few examples of how you might want to adjust your setup. 

Split Shot Placement
Split shot placed above the fly

The Clinch River often has long, slow slicks that maintain fairly consistent depths. Consequently, the weight of the fly alone should be sufficient to get and keep the fly where I want it. In a 6’ deep plunge pool in the Smokies, I’m going to need a lot of weight to get my fly deep and keep it there because of the water depth and turbulence. I’ll likely use a heavily weighted fly plus a few pieces of split shot placed near the fly. But fishing pocket water in the Smokies, the depth in one pocket probably varies from 12-24”, with a lot of fast currents. Here, I would probably use a lightly weighted (or un-weighted) nymph with one or two split shot placed 6-8” above the fly. This will keep everything down but allow the fly to drift just off the bottom where it won’t hang up as much.

Split Shot Placement
Split shot placed below the fly

There is another method that some anglers use where a separate piece of tippet is added to the leader or to the back of the fly. The desired number of split shot are then added to that piece of tippet, allowing the fly to remain above the weight. It works, but I find that split shot hanging on a loose, vertical line like that have a greater tendency to get hung up and pulled off on rocks. As with most things, you sometimes have to play with a few methods and figure out what works best for you.

There are, of course, different sizes of split shot and what size you use can certainly determine how many you need to use. I typically use small to medium size shot because it gives me more flexibility and versatility to add or remove as needed.

In any case, if you are only nymphing with a weighted fly under a strike indicator, you are just scratching the surface of nymphing. I encourage you to experiment with different amounts of weight and different weight placements. You’ll probably start catching a few more fish… and maybe a few bigger ones, too!

How Stuff Works: Fly Categories

Box of Wet Flies

If you’re new to the sport, sometimes it is difficult to navigate all of the terminology. There is probably no facet of fly fishing where that is more complicated than in the world of flies. I’m not even talking about specific names of flies. That water can definitely get over your head in a hurry. Before you can even begin to make sense of those fly pattern names, you have to get a handle on the more general categories under which they fall. And that’s what we’re going to tackle here.

Let’s start with the term flies. I frequently hear it misused as its own separate category. For instance, someone might ask me if we’re going to be using flies or nymphs. That’s kind of like asking if you have a poodle or a dog. Of course, a poodle is a type of dog. And a nymph is a type of fly. Regardless of what it is supposed to imitate, any lure that we fish with a fly rod is generically referred to as a fly. Flies are then broken into more specific categories.

Dry Flies

Popping Bug
Popping Bug

While it can certainly be broken down to more specific sub-categories, the main category of Dry Flies refers to any fly that is designed to float and be fished on the surface. This would include something like a Parachute Adams that might represent some sort of adult mayfly. It would include a Dave’s Hopper that imitates a land-based grasshopper that has ended up in the water. Or it could even be a large, hard-bodied popping bug used for bass fishing.

One might fall under the sub-category of Trout Flies, another under Terrestrials, and another under Bass Bugs.  But they are all flies because they are fished on a fly rod and they are all dry flies because they float on the surface.

Nymphs

Hare's Ear Nymph
Hare’s Ear Nymph

Nymphs are a category of flies that you typically fish under the surface and more specifically; they imitate the juvenile stage of an aquatic insect. A Tellico Nymph, for instance, represents the juvenile stage of a stonefly. A Pheasant Tail Nymph imitates, most often, the juvenile stage of a mayfly. Most nymphs drift helplessly in the current and we use tactics that allow our imitations to do the same.

To confuse things a little, some flies that don’t imitate juvenile stages of aquatic insects get lumped into the nymph category because they are fished like nymphs. For instance, a Green Weenie is a representation of an inchworm that has fallen into the water. Though an inchworm is obviously not a juvenile stage of an aquatic insect, when it falls in the water, it sinks and drifts helplessly with the current. So, you fish its imitation like a nymph. Sowbugs and scuds are other good examples of this. They are actually crustaceans that will never hatch into an adult that flies from the water. But their imitations are most often fished like other nymphs, so they fall into the nymph category.

Wet Flies

Early Wet Fly
Typical Wet Fly

The category of Wet Flies is a little confusing and could probably be more of a sub-category of Nymphs – or vice versa. Wet flies are usually not tied with materials that allow them to float. They are also not really designed to sink. Rather, they often have a soft hackle that provides a lot of motion and you commonly fish them on a swing rather than a drift. So, you mostly fish them in, or just under, the surface film. A wet fly could imitate a variety of things. Mostly they are suggesting a mayfly or caddisfly as it is emerging to hatch.

Streamers

Clouser Minnow
Streamer: Clouser Minnow

Streamers are also flies that sink but more specifically, imitate things that swim. Again, anything you fish on a fly rod is generically referred to as a fly, but these flies represent things like minnows, crayfish and leeches. So unlike nymphs that you usually fish on a dead drift, or wet flies that you usually fish on a swing, you typically strip and actively retrieve streamers through the water.

Naturals and Attractors

So you can take all of the flies that are out there and lump them into four categories: Dry Flies, Nymphs, Wet Flies and Streamers. Now, you can take all of those and split them into another two broad categories: Naturals and Attractors.

A Natural is a fly that specifically imitates something that exists in nature. A Blue Wing Olive dry fly specifically imitates a Blue Wing Olive mayfly adult. The Hot Flash Minnow Shad is a streamer that specifically imitates a threadfin shad. A Green Weenie imitates an inchworm. They’re all fly patterns intended to represent something specific.

Hot Flash Minnow Shad
Hot Flash Minnow Shad

You most often fish naturals when fish are keyed in on a specific food source and you know what it is. If there is a big hatch of Blue Wing Olives, trout may not eat anything that doesn’t look like a Blue Wing Olive. Or because stripers are working a school of threadfin shad, they may not consider anything that doesn’t look like a threadfin shad.

Attractors are flies that don’t look like anything in particular. They are also sometimes called Generals or Prospecting Flies. They might just be something very generic that looks like a lot of things. Or they might be something that doesn’t look like anything at all. They may just have a certain color or other trigger that generates a feeding response from a fish.

Most of the time, you are fishing with attractors, especially in places like the Smokies where fish are more opportunistic. There are rarely big enough hatches in the Smokies to allow a fish to efficiently key on one particular bug. You fish things like a Parachute Adams because it resembles a lot of things fish might see on the surface. Or you fish a Prince Nymph because it has characteristics that trigger a feeding response from a fish.

Wooly Bugger
Wooly Bugger

If you’re fishing for smallmouth and you’re not sure what they’re feeding on, you might tie on a Wooly Bugger. Depending on its color scheme and how you fish it, it could pass for a minnow, leech or even a crayfish. Essentially, it just looks like something to eat.

Yes, flies and the vocabulary that describes them can be confusing. Hopefully this article has helped a little. Don’t get frustrated. Embrace and enjoy the chaos. It’s all part of the fun!

February Fishing Forecast 2019

Tennessee Winter Rainbow Trout
Winter Rainbow

Smoky Mountains

Winter fishing in the Smokies is not usually productive, at least not consistently. And I don’t expect this February to be an exception. We’re off to a very cold start with water temperatures right at the freezing mark. Hopefully we can at least get a break from all of the recent rain and keep water levels respectable.

If water levels are cooperative, one of the best things about fishing the park in the winter is the solitude. You will likely only see a handful of other people and probably no other fishermen. Embrace the solitude and significantly lower your expectations on activity and you can have a pretty enjoyable day!

And keep an eye on the weather. In recent years, we have had some brief warm stretches in late February a few warm days in a row can turn these fish on and showcase some fairly good hatches. Little Black Stoneflies, Little Black Caddis and Blue Wing Olives are all common during the late winter months.

Clinch River

The Clinch can fish well in the winter because it’s a tailwater and its water temperatures remain pretty constant. The water temperature in February is nearly the same as it is in August. However, we are still paying for a VERY wet 2018.

The Clinch is not only releasing water all day every day, they are sluicing approximately 6500 cfs. That’s a lot of water. You definitely can’t wade it under those conditions and it’s really too much water for decent fishing from a boat.

If they relax that water release schedule, this will be a good option. But it looks like this is what we’re stuck with for a while.

Delayed Harvest

The delayed harvest streams in the Cherokee National Forest are the best things going right now. Stocked fish continue feeding more regularly in winter than wild ones do. They’re not as good as they were in the fall, mainly because of poaching, and the later in the DH season we get, the fewer fish there are. But there are still some fish, particularly in the Tellico, and they should remain active through February. Assuming roads remain clear and safe to drive on, this is probably your best bet right now.

Flies: Prince Nymph

Prince Nymph Fly Pattern
Prince Nymph

Whether describing a nymph, dry fly or streamer, an “attractor pattern” refers to a fly that doesn’t really imitate anything in particular. It could be that the fly is relatively generic and looks like a lot of different things. An Adams dry fly, a Pheasant Tail Nymph or a Wooly Bugger would all match that description. An attractor could also be a fly pattern that really doesn’t look like anything at all.

I think the Prince Nymph definitely matches that second description. Its body, hackle and general color scheme might suggest some sort of mayfly nymph or caddis larva. Though it’s thick, split tail is more reminiscent of a stonefly nymph. But those white “horns” on the back? While I don’t know of any aquatic insect that has anything like that, perhaps it is suggestive of the white back on an Isonychia nymph. But there certainly don’t need to be Isonychia nymphs present for this fly to work.

That’s because this fly works well nearly all of the time and in most any environment. In mountain streams and tailwaters, this fly catches trout. In spring, summer, fall and winter, this fly catches trout. It’s no wonder this is one of the most popular nymphs of all time and why it would be on nearly every trout fisherman’s must-have list. Nobody seems to care what it imitates or if it makes sense. Because it makes sense to the trout and that’s all that matters.

Apparently, it also made sense to Doug Prince, the originator of the pattern. Doug was an innovative fly tyer who didn’t get a lot of recognition because he mostly tied for himself, rather than producing fly patterns for shops and catalogs. It is believed that he created the Prince Nymph sometime in the early 1940’s. He called it a Brown Forked Tail Nymph and fished it primarily on the King’s River in California.

One of Doug’s fishing buddies was Buz Buszek, a fly shop owner in California. Apparently Buz was in a rush one year to put out a catalog and wanted to include a peacock body nymph pattern. He decided to use Doug’s pattern but couldn’t remember that it was called a Brown Fork Tailed Nymph. He did, however, remember that it was Doug Prince’s pattern, so he put it in the catalog as the Prince Nymph. The name stuck.

Beadhead Prince Nymph Fly Pattern
Beadhead Prince Nymph

Because of its popularity, there have been countless variations of this fly over the years. Everyone seems to think they can take a great fly and make it better. While some are made with wire bodies and some have rubber legs, others use a flashy dubbed body or have a flashy, reflective material on top, in place of the traditional white goose biots. One of the earliest and probably most popular variations was the addition of a bead head.

Over the years, I’ve had success on most all of the variations. But in my opinion, nothing beats the old standard for catching fish in the Smokies. I tie and fish them in sizes #16 – #8, but most often use a #14. And I have success with them all year, but seem to do best with them in the “fringe months,” when the water temperature is a little colder than ideal. In fact, the Prince Nymph is one of my most productive winter patterns, fished deep and slow.

So, if you’ve done much fly fishing, you likely know this pattern already. If not, definitely add some to your fly arsenal. The pattern for the traditional version is included below.

Prince Nymph

  • Hook: 2XL nymph hook, sizes 16-8
  • Thread: 8/0 claret
  • Weight: Non-lead wire to match hook size (typically .015 or .020)
  • Rib: Small to medium gold oval tinsel
  • Tail: Two brown goose biots, divided
  • Body: 2-4 strands of peacock herl (more on larger hook sizes)
  • Hackle: Brown hen feather
  • Wing: Two white goose biots, divided

How Stuff Works – Tenkara

Tenkara Fishing Smoky Mountains
Fishing with tenkara

Many of you have already entered the world of tenkara. Others have probably at least heard a little bit about of it. Many fly fishers think its the greatest thing that’s ever happened, and just as many more think it’s just plain stupid. Regardless of what you may think, what many thought was a passing trend appears to be here to stay. So let’s learn a little something about it.

The Big Picture

By definition, tenkara is an old, simplistic form of fly fishing that comes from Japan. The reason many think of it as simplistic is that there are very few moving parts. There is no reel and no extra line. There is just a single length of line that is attached to the tip of the rod.

The rods are on the longer side, typically 10 – 12′, but there are shorter and longer versions. This method of fishing often involves a single cast and the length of the rod is used to reach and keep much of the line off the water. So, it’s a long rod with a single length of line attached to the end? Isn’t that just cane pole fishing? Yes.

Anyone who tries to tell you differently is lying to you or themselves. It has been marketed as this revolutionary style of fly fishing, but it really is no different than fishing with a cane pole. But there’s nothing wrong with that. Old timers in the Smokies fished this way for decades and caught A LOT of fish.

Tenkara USA Rod
Typical tenkara set-up

The only thing that makes it different is the use of more modern materials. Rods used for tenkara are made from carbon fiber and are very light weight. They are also telescopic, so that 12′ rod travels at about 18″. The tips are very fine so they have an incredible amount of feel. Old cane poles were long and heavy.

The lightweight and packability is a big reason they are so popular. They are just really easy to throw in a backpack. But many seem to think their simplicity equates to less stuff to carry, and I just haven’t found that to be true. You may not need to have a reel, but you still need wading gear, flies, tippet, snips, water, etc. Sure you can just take the rod and some flies, but you could do that with a conventional fly rod. You’ll just have a reel on the end. The simplicity is more with the technique.

The Technique

We have a tendency to complicate things. I can use a conventional fly rod and use the same techniques as you would with tenkara. I’ve done it for years. But when you add a reel full of line, many people want to cast farther than they need to, and consequently end up with too much line on too many currents, resulting in a poor presentation. When you remove the extra line from the equation – when you can only use a fixed amount – you are forced to read water and properly position yourself. And the longer rod allows more reach to do those things.

There are times when you need to make longer casts. In long, slow pools, you often can’t get close to the fish without spooking them. Tenkara can put you at a significant disadvantage in these situations. I can’t think of too many places on the Clinch River, with its long slicks, where tenkara would be very practical. But in the Smokies, where we have a lot of pocket water and riffles, it’s deadly.

The Gear

Tenkara Lillian

Again, a tenkara rod is just a long, telescopic rod with no place for a reel. Since there is no extra moving line, there are no guides on the rod. At the tip of the rod is a permanently affixed piece of cord, called the lillian. You attach your line here.

There are a few types of line used for tenkara. Some prefer a braided line with a length of tippet on the end. Others use a long, single piece of heavy, often colored, piece of mono with a length of tippet on the end. I build a specific line when I fish tenkara. I build a taper with different diameters of colored mono and attach the appropriate size tippet to the end.

Tenkara Line Tender
Wheel style line tender

There are also a number of different line tenders you can use when you want to break down the rod but keep the line and fly attached. Some of these devices are actually on the butt of the rod and you wrap the line around them. Others are a separate wheel that you wrap the line around and slide the wheel on the rod. The more popular this becomes, the more gadgets appear.

You can also find specific tenkara flies. They always seem to be tied with an unusual inverted hackle. I’m sure they catch fish but I never bought into this. I choose flies based on fish, stream, season and conditions – not what type of rod I’m fishing.

Learn More

This is very much an overview. A quick Google search of tenkara will provide a lot more details. Tenkara USA is one of the better companies selling this gear and they have a number of instructional videos on their website to help with everything from rigging to technique. Of course, I am always happy to help with any of this on a guide trip, as well. Bring your own rod or use mine if you’re just wanting to get a taste.

Squirmy Worm

Pink Squirmy Worm Fly Pattern

Many fly fishing purists cringe at the idea of fishing a worm pattern. I’m not sure why since a major part of fly fishing is matching the food source of the fish. And worms are a major food source for fish everywhere.

I think it’s the same hangup that many traditionalists have with strike indicators. They just don’t want to participate in any sort of activity that resembles bait fishing. I suppose that fishing a worm pattern under a strike indicator is about as close to bait fishing as you can get. However, when you really think about it, it’s no closer to bait fishing than using a Prince or a Pheasant Tail. It’s not as if the worm is real, or even scented. In either situation, you’re using an artificial imitation of a food source to fool a fish.

The San Juan Worm has been the main target of ridicule for many years. It gets its name from the San Juan River in New Mexico, where it imitated the many aquatic worms in this river. But worms are not isolated to the San Juan River. They are abundant in nearly every body of water, even more so where softer, muddy banks exist.

Red San Juan Worm Fly Pattern
Traditional San Juan Worm

Worms tend to burrow in muddy banks and when water rises, it floods worms out of those burrows. We see the same thing at our homes. After a good rain, you see an abundance of worms found on the pavement. They were flooded out of their homes. Worms that live in a river bank don’t end up on the driveway when their burrows are flooded. They end up in the river and fish seek them out.

Worm patterns can be intermittently effective anytime. But the best time to fish them is during, or just after, a good rain when the water level rises. In essence, you’re matching the hatch in these situations. Again, isn’t that the idea? So, in freestone streams like the Smokies, these changes in water levels are periodic. But on tailwaters like the San Juan, changes in water levels are daily.

The Squirmy Worm is not exactly a ground breaking fly pattern. You use the exact same technique as a San Juan Worm with a different material. Traditional SJW’s used vernille or micro chenille for the body. The Squirmy Worm uses a rubbery material which makes it more lifelike.

Rubber Squeeze Toy Fly Tying Material
Old school squirmy material

I’ve tied them for years, long before Squirmy Worm was in the fly fishing vocabulary. Many fly tyers have. But what is now mass marketed as Squirmy Worm material didn’t exist. We used things like rubber tentacles off of children’s toys. They worked great, but the new material is made for fly tying and allows for longer, more uniform bodies.

Spirit River Squirmy Worm Material
New squirmy material

The Squirmy Worm is available in a number of different colors. Pink and red are my two favorites. And you can get them with or without beads. In either case, note that the rubbery material of this pattern can give it sort of a neutral buoyancy when using minimal weight. If you really want to get it down, you may have to use a little more weight than normal.

For you fly tyers, it’s not a complicated pattern to tie. However, the Squirmy Worm material can be a little awkward to work with, as it rolls on the hook. It’s also easy to cut through the material with fly tying thread. There are a few ways to deal with that. My preferred method is to apply a small amount of dubbing to the thread before wrapping around the rubber material.

It’s ugly and it’s trashy, and it very well may be one step away from bait fishing. But it sure does catch fish!

January Fishing Forecast

West Prong Little River Snow

Smoky Mountains

Winter fishing in the Smokies is not usually productive, at least not consistently. And I don’t expect this January to be an exception. In addition to the cold water temperatures that keep these wild trout fairly inactive, it looks like our wet weather will continue. Water levels will probably remain pretty high most of the month.

If water levels are cooperative, one of the best things about fishing the park in the winter is the solitude. You will likely only see a handful of other people and probably no other fishermen. Embrace the solitude and significantly lower your expectations on activity and you can have a pretty enjoyable day!

Clinch River

The Clinch can fish well in the winter because it’s a tailwater and its water temperatures remain pretty constant. The water temperature in January is nearly the same as it is in August. However, we are still paying for a VERY wet 2018.

The Clinch is not only releasing water all day every day, they are sluicing approximately 5900 cfs. That’s a lot of water. You definitely can’t wade it under those conditions and it’s really too much water for decent fishing from a boat.

If they relax that water release schedule, this will be a good option. But it looks like this is what we’re stuck with for a while.

Delayed Harvest

The delayed harvest streams in the Cherokee National Forest are the best things going right now. Stocked fish continue feeding more regularly in winter than wild ones do. They’re not as good as they were in the fall, mainly because of poaching. But there are still plenty of fish and they should remain active through January. Assuming roads remain clear and safe to drive on, this is probably your best bet right now.

On the Fly – Unwinding a New Leader

I get to see a lot of things as a fly fishing guide and instructor. Few things make me cringe more than watching someone pull out a new leader and start yanking at either end. The result is inevitably a rat’s nest and nobody wants to start their day that way. It’s an easy thing to avoid and this quick tip will help you get start the day on the right foot!

How Stuff Works: Sink Tip Fly Lines

Rio Sink Tip Fly Line
Sink tip fly line

Floating fly lines are by far the most common, and for most trout fishing situations, they are all you need. When nymphing below the surface, weight in the fly or on the leader (split shot) is enough to get the fly and leader down where it needs to be. Doing this while the fly line is still floating can be advantageous as it allows the line to be mended when necessary and provides for quicker pick up when setting the hook on a dead drift.  Even when fishing with streamers, a floating line is often adequate when stripping a weighted streamer through shallow trout streams.

But what if you want to get a streamer down and keep it down when retrieving it through deeper, swifter water? Such scenarios might include a mountain trout stream that’s running high from recent rain, or a tailwater fishery during generation. Both of these scenarios have produced some of the largest trout I’ve ever caught. Or what if you’re wanting to fish a streamer 12’ deep in a lake for stripers?

Performing the above tasks with a floating fly line would require a very heavy fly with a long leader. And the result would be extremely difficult casting and very limited “contact” with the fly. When fishing streamers, shorter leaders allow you to better control the motion of the fly when retrieving it, and give you much quicker feedback when the fish takes it.  Additionally, because of the floating fly line, the fly would rise with every strip of the line rather than staying deep in the target area.

Breakdown of a Typical Sink Tip Line
Breakdown of a typical sink tip line

A sink tip fly line solves these problems by allowing the front portion of the fly line to sink. Weightless flies that are easier to cast and sometimes have better “action” can be used and so can shorter leaders. And with the fly line submerged, the fly will stay down and retrieve more in a straight line rather than upward toward the surface. Full sinking lines can also be used for this task but can be clumsy to cast and nearly impossible to mend. A sink tip line more or less gives you the best of both worlds.

Sink tip fly lines have a number of variations. First, they will often have different lengths of sinking heads. In other words, the entire fly line will float except for the front 6’ or 15’ or whatever the case may be. In general, a shorter head will be easier to cast. A longer head will keep more of the line, and consequently the fly, down deeper. They will also come in different sink rates. Some manufacturers may provide a measurement in grains but most will be designated in a class – like a class 5. A Class 5, for instance, will typically sink at a rate of approximately 5” per second. A Class 2 will sink at approximately 2” per second. They commonly range from Class 1 (often described as an intermediate line) to Class 6.

Sink Tip Fly Line Sink Rates

Very often, the weight classes will correspond specifically with the actual line size. For instance, you may find a 10-weight sink tip line that is a Class 5, or a 6-weight sink tip line that is a Class 3, but there may not be an option for a Class 5 6-weight.

Sinking Poly Leaders
Sinking “leaders”

You can also find separate add-on sink tips to convert any floating line into a sink tip. This is convenient if you don’t want to carry an extra spool or if you don’t plan to fish sink tip lines frequently and don’t want the expense of an extra spool and line. However, my experience with these is that they hinge at the connection with the floating line and cast terribly.

As with nearly everything in fly fishing, you need to figure out what’s best for your task at hand. Where are you going to be fishing? What are you trying to do? What size rod will you be using?

Hopefully, this sheds a little bit of light on sink tip lines. They can be terribly confusing, mainly because every manufacturer seems to have their own way of describing them. You really need to read through the fine print in the description of the lines to figure out what’s what. Your best bet is to talk to someone at a local fly shop. They can really break down the differences for you.
