How Stuff Works: Strike Indicators

There seems to be few things in the fly fishing world that provoke as much debate as strike indicators. The mere existence of strike indicators in the sport of fly fishing can inspire rants from fly fishing purists that rival any political rant of that friend you just hid from your Facebook feed. But even among the firmly pro indicator crowd, nymphers will argue fiercely about the superiority of one type of indicator over another.

For newbies to the sport, a strike indicator is something that is often used while fishing with nymphs (sub surface flies). It is a brightly colored, floating object that is affixed to the leader intended to give the fisherman a visual indication when the fish hits his submerged fly, or nymph. Since the nymph usually can’t be seen under the water, and since it is usually fished with a slack line to achieve a dead drift, the strike can be difficult to detect without the visual aid of a strike indicator. Strike indicators can also be helpful in making sure the nymph is drifting properly (without drag) and at the desired depth.

The obvious question usually arises when hearing this description, “Isn’t that just a bobber?” Pardon the bobber pun, but that opens a whole other can of worms. There are a number of fly fishermen who will stop just short of taking a swing at you if you call a strike indicator a bobber. I assume this animosity stems from the association of bobbers with bait fishermen and fishing live bait; and fly fishermen don’t like to think anything they do might resemble bait fishing. So they call them strike indicators. The truth is that while strike indicators are typically smaller, lighter, and made from different materials than bobbers, they pretty much accomplish the same thing.

I use the term strike indicator because I think there is enough of a difference to specify, kind of like I don’t refer to a hamburger as a sandwich. It’s just different enough. But I won’t be offended if you call a hamburger a sandwich and it won’t offend me if you call a strike indicator a bobber!

Getting re-focused specifically on strike indicators, there are a lot of different kinds, and that’s what I want to focus on here. As mentioned before, most fly fishermen have their favorites, and a lot about selecting strike indicators will boil down to

personal preference. I personally don’t think there is such a thing as the perfect strike indicator. They all have pros and cons and I use different ones for different situations. Often I don’t use one at all, but that’s a topic for another article. Below is a list of some of the more common or popular strike indicators with a description of how they work and some of their strengths and weaknesses.

Hard Toothpick Indicators: These are usually made of cork, or balsa, or something similar. They are typically round or oval with a hole drilled in the center. The leader/tippet is inserted through the hole and the indicator may be moved to any position on the leader. Once the desired position is determined, the provided “toothpick” is inserted into the hole to hold the indicator in place.

These are great because they are buoyant, highly visible, reusable, and can easily be adjusted up and down the line to set the nymph at different depths. However, they tend to make more disturbance when they land on the water and can spook more skittish fish. Additionally, their mass makes them difficult to cast when placed on the tippet portion of the leader for shallow nymphing, though smaller ones can be purchased. They are best for deep to mid-depth nymphing and for quick and easy depth adjustment.

Hard Rubber Band Indicators: These are typically oval in shape and made from the same materials as the hard toothpick type indicators. Instead of having a hole and a toothpick, they have a slit that contains athick rubber band. The leader is inserted into the slit and the indicator is then rotated, allowing the rubber band to twist around the leader to hold the indicator in place.

They have pretty much the same pros and cons as the toothpick indicators. One additional advantage is they can be added or removed while the fly is still attached. However, they have a tendency to kink the leader when twisted on, and they come off the line more easily than other indicators when casting.

Thingamabobber

Balloon Style Indicators: The best known versions of these are the Thingamabobber and Air Lock. These are basically small, plastic balloons. They float great, are highly visible, and can be easily adjusted. They are particularly good if you need an indicator that will suspend larger, heavier flies. The Thingamaboober attaches by looping the leader through a hole and around the indicator. The Air Lock has a slot in the base where the leader is inserted and a separate piece that screws on to hold the indicator in place.

 

Air Lock

Much like the other hard indicators, when this indicator is set in the tippet section of the leader for shallow nymphing, it is difficult to cast and can create more tangles. It also lands hard on the water. It is more durable and floats better than the other hard indicators.

 

 

Stick-On Indicators: These are small round or oval pieces of foam that peel off and stick on to the leader. Their greatest value is that they cast easily, even when placed on the tippet and they make very little commotion on the water. So they are a great indicator for shallow nymphing. They float great and multiple indicators can be added to the line to support more weight.

The biggest downside to these is they are not reusable and they are not easily adjusted. When moved they lose a lot of their stick and then have a tendency to slide down the leader. They can usually be moved a few times before you have to trash them. Some complain that they also leave a sticky residue on the leader but I haven’t found that to be a problem.

Yarn Indicators: These are made from a buoyant yarn that is often pre-treated with a waterproofing agent, but floatant may also be added. There are a number of different versions of yarn indicators, but most attach by using some sort of slip knot or loop knot. Like the stick-ons, yarn can be attached to the tippet end of the leader without the worry of a hard landing or a lot of tangles. So this is another good choice for shallow nymphing. Yarn indicators are also very sensitive, so they are great for detecting subtle strikes.

On the downside, I find them difficult to add and remove from the line and when removed, they regularly leave kinks in the line. Larger yarn indicators can be wind resistant and difficult to cast in tight places and they require a little more maintenance to keep them floating.

Putty Indicators: Strike putty comes in a small tub and resembles Play-Doh. You pull out a small gob or big gob depending on how big you want your indicator to be, and you smoosh and roll it on your leader. One of the benefits it that you can smoosh more on if you need more flotation for bigger, heavier flies, or you can pick some off for smaller flies and spookier fish.

I’m trying to be impartial here but I don’t like this stuff. It always comes off, especially in warm weather. It leaves a permanent indicator-colored smudge on your line when you remove it. Finally, every bit of dirt in the vicinity attaches to it, so what starts as orange strike putty soon becomes and greyish, brownish, greenish, orange strike putty.

Dry Fly: In the right situations, a dry fly can serve as an edible strike indicator by adding a nymph “dropper” to it. For many, this is the go-to method because you’re essentially doubling your chances… or so it might seem. Just like any other strike indicator, a dry fly has its pros and cons.

Obviously, one of the big perks is that you have the potential to catch a fish on the nymph or the indicator, since the indicator is a fly. However, most dry flies don’t have near the buoyancy as an actual strike indicator, so if you’re needing to get heavier nymphs near the bottom of a deeper run, the dry fly will routinely get dragged under. In such a scenario, you’re not fishing the dry fly or the nymph very well, and hardly doubling your chances.

The best scenario for fishing a dry fly with a dropper is when you don’t need to get your nymph very deep, and you can fish a dry fly buoyant enough to support the nymph’s weight. I immediately think of pocket water. Another scenario might be in flatter water during a hatch, where you could put a nymph with little to no weight behind a dry fly to suggest an emerger.

The takeaway from all of this should be that there is not one strike indicator that is going to be perfect for every situation. You will likely need a variety to meet a variety of conditions. As with most things, much of it will boil down to personal preference and you should play around with a few different types to find what best meets your needs.

How Stuff Works: Reels

Classic Fly Reel

Compared to most spin and bait casting reels, fly reels are pretty simple. Yes, there are always exceptions, but the typical fly reel has a single, direct drive, where one rotation of your hand equals one rotation of the reel. There have, over the years, been multipliers and automatic reels, but all of the extra gears required for them add a significant amount of weight (more on the importance of reel weight later), just to perform a task that usually isn’t necessary.

The drag on a fly reel is also fairly simple. Drag, as it pertains to reels, just refers to the amount pressure the reel puts on the spool as it rotates. In other words, if you’re playing a fish on the reel, when he runs, the reel will apply a preset amount of pressure on him that is determined by your drag setting. Most fly reels will have some version of either a disc drag or a spring and pawl drag.

Common Drag Systems

Disc drags are quieter, apply smoother pressure and allow for significantly more variations in resistance. They are often the choice for fish that may be larger or that make long, strong runs. Spring and pawl drags are lighter in weight and provide a classic “clicking” sound desired by many fishermen. They are often the choice for smaller, lighter rods and when fishing for smaller fish.

More expensive reels, particularly those used in saltwater, tend to have fairly sophisticated drag systems. Orvis had a reel a few years ago that touted a drag system modeled after the brakes used on fighter jets! That’s not a bad thing to have if you’re playing a 150 lb. tarpon, but may be a bit over the top for an 8” Smoky Mountain brook trout! The other thing that significantly impacts the price of a reel is how it is constructed and the material from which it is made.

In addition to possibly plastic components in the drag system, less expensive reels will often be made of a lower grade, softer aluminum that is cast from a mold. This will result in a reel that is a little heavier and a little more prone to denting or bending. In addition to non-corrosive, stainless steel (or similar) drag components, often in a sealed housing, higher end reels will be machined from a high grade, bar stock aluminum. This will result in a reel that is lighter, more resistant to the damages of saltwater, and much more durable.

Large Arbor Reel

Another fly reel feature that is becoming more and more common is a larger arbor. Traditionally, fly reels had a very small spindle to which the line attached. A significant amount of backing was put on the reel before attaching the fly line to fill space on the reel. Otherwise, the fly line would come off in smaller, tighter coils and be difficult to keep straight. Mid and large arbor reels are a little wider than traditional reels and have a much larger “spindle.” This not only allows you to retrieve more line in one turn of the reel, but it doesn’t require as much backing. You still want some backing as an “insurance policy” if you hook a bigger fish, but you don’t need 100 yards of it like you did on traditional reels.

If you’re going to be fly fishing in saltwater, the reel is probably THE most important piece of equipment you’ll purchase. However, for most freshwater fly fishing situations, the reel is one of your least important pieces of equipment. Certainly it still has an important function, to store all of your line, but that’s about it. Most of the time when fishing for trout, or bass, or bluegill, you’re going to be playing the fish by hand, stripping the line under the finger on your rod hand to bring the fish in.

So if you’re looking for an outfit for saltwater or even something like salmon or steelhead, and you have a set budget, put as much money in the reel as you can and skimp on the rod. If you’re looking for a freshwater outfit for say, trout or bass, put far less in the reel and more in the rod and line.

Reel Art

However, for many fly fishermen, reels are almost like jewelry. I know guys that fish for nothing but mountain trout and have $600 reels. They think they’re “neat.” Some reels even have elaborate artwork on them to appeal to the “jewelry crowd.” Sometimes we make choices because they’re practical, and sometimes we make choices because they make us happy. If you have the disposable income and want to buy a $600 reel with a drag system that stops fighter jets to put on your 8’ 3-weight trout rod, have at it! But you don’t need to.

Regardless of your budget, there are a couple of things that you’ll want to make sure that you get in a reel. One, make sure it has enough of drag resistance to prevent the reel from ‘free-spooling” when you strip line from it. Second, make sure that the reel is an appropriate size for your line and rod.

Most reel models will come in different sizes for this reason. Heavier fly line weights will take up more space on the reel so you need a bigger reel to accommodate them and the appropriate amount of backing. On a similar note, rods that cast heavier lines weigh more and need bigger, heavier reels to balance them out. Regardless of how heavy or light your fly rod is, if you don’t have a reel that balances it out, it’s going to feel awkward in your hand. It’s much like carrying two buckets of water rather than one. Two buckets might be heavier overall, but will be more comfortable to carry because they balance each other out. You can view the specs on any reel and see what its weight and line capacity is.

How Stuff Works: Polarized Sunglasses

I once heard a highly regarded fly fisherman say that he considered polarized sunglasses to be his most important piece of gear. These sort of statements always amuse me because I can’t help to wonder how important those sunglasses would be if he didn’t have a rod or a line or a fly! But I definitely get what he meant. While polarized sunglasses may not be THE most important piece of gear, they are often the most underestimated by many fishermen.

Polarized Sunglasses

Many fishermen, particularly those new to the sport, probably underestimate them because they don’t understand the difference in sunglasses and polarized sunglasses. They see sunglasses as merely a means of protecting your eyes from bright light and may opt not to wear them at all on overcast days or when fishing in shadier locations like the mountains. While polarized sunglasses do protect your eyes and reduce eyestrain in bright conditions, they have far greater importance when it comes to tactical applications.

Light usually scatters in all directions, but when it’s reflected from flat surfaces, it typically becomes polarized, travelling in a more uniform (usually horizontal) direction. This creates a serious intensity of reflected light that causes glare and reduces visibility. The more reflective that flat surface is, the more intense the glare will be – consider how a signaling mirror works.

Looking Through Polarized Lens

Water has highly reflective properties and basically acts like a mirror that intensifies those reflected rays even more. I’m sure everyone can think of instances when driving where significant glare was encountered. More than likely, the worst glare you ever encountered when driving was during or right after a rain. Pavement is a flat surface that can reflect light and cause glare. Wet pavement intensifies that reflection and creates more intense glare. With that in mind, it stands to reason that you will get even more intense glare when light reflects off the surface of lakes, rivers, streams, etc.

So, “regular” sunglasses will help in these situations by essentially darkening this reflected light, making it less stressful to your eye, but the glare will still be there and will prohibit you from seeing anything on, or in the case of water, under that surface. But the chemical filter on the lenses of polarized sunglasses is designed to absorb horizontal light waves, while still allowing vertical waves to pass through. Because light only travels in one direction through polarized lenses, glare is eliminated, or at least reduced.

Contrary to what I believe many anglers expect, this technology does not create “magic fish-seeing glasses!” Fish will not suddenly be visible when you put on your polarized glasses, but with better ability to see through the water, you will be much better equipped to spot fish. However, the most consistent benefits you will receive from polarized glasses are the ability to better see your dry fly on the surface, and the ability to read water by better recognizing slower seams and deeper troughs and pockets. Additionally, being able to better see the stream bottom will allow for easier, safer wading.

Just how well your polarized glasses eliminate glare often depends on the angle the light hits and reflects off the water. There will be times on bright sunny days when the light reflects at such a severe angle that even the polarized lenses don’t seem to help. During these times, your best bet is to change the angle the light is hitting your eye by repositioning. For example, you may be on the left side of the stream facing and fishing toward the right and encounter an insurmountable amount of glare. Often by fishing from the other side of the stream and facing/fishing the other direction, you can totally eliminate the glare.

Even on overcast days or in shady areas, you can encounter significant glare, so I almost always wear polarized glasses when fishing. This is where lens color becomes important. Darker lens colors, like gray, will block more light, making them more ideal for bright conditions. They also work well on deep blue water and better maintain true color. But they block a little too much light in low light conditions like overcast, heavy shade, or dawn and dusk, which offsets the benefits of polarization.

Lighter lens colors, like yellow or rose, allow more light in and are perfect for fishing in low light conditions. They often even make things appear brighter. But in bright conditions, you want something that will filter light, not magnify it, so these are not good choices for sunny conditions on open water.

If you plan to fish a lot and expect to fish in a variety of different light conditions, you may find it beneficial to have multiple pairs of polarized glasses in different lens colors. But if you’re looking for one, multi-purpose lens color, an amber, copper or brown color sort of fits right in the middle. And these lens colors work particularly well in shallow water where most fly fishermen operate.

Fitover Glasses

The shape of the frames can also be a factor in how well the glasses work. Frames that “wrap” more will help prevent direct and/or reflected light from entering on the sides. “Straight” frames, like an aviator style, allow more light in from side and rear angles. While prescription polarized sunglasses are available they can be problematic in a wrap style frame. Essentially, you’re dealing with a bent lens on a wrap style frame. The stronger the prescription and the more severe the bend in the lens, the more distortion you’ll get when looking side to side. Straight frames are better suited for prescription sunglasses.

If you wear corrective lenses and prefer the benefits of a wrap style frame or if you simply don’t want to fork over the money for prescription sunglasses, there are a number “fitover” sunglasses that are designed to be worn right over your regular eyeglasses.

How Stuff Works: Leaders & Tippet

It’s nearly impossible to talk about leaders without talking about tippet, and vice versa. However, we could go into an enormous amount of detail on either of them – so much so that it would defeat the intended purpose of a brief monthly article that attempts to provide a simple definition of how particular pieces of fly fishing gear “work.” So, consider this a broad introduction of how the two things work together as part of the overall fly fishing “system.” We’ll talk about each individually in more detail in future articles.

Typical Leader and Package

The leader is the monofilament (usually) connection between the weighted fly line and the fly. Most commonly 7’ to 12’ in length, the leader is typically tapered and consists of three parts: the butt, the taper, and the tippet. These parts can be completely separate and easily distinguished in formulated leaders that are created by knotting different diameters of monofilament together. However, most commercially produced leaders are created with an acid process that results in a knotless, seamless taper from top to bottom.

In either case, the butt is the thickest section that attaches to the fly line. Its purpose is to “turn the leader over” with the cast. A leader with no butt, or too thin of a butt, has a tendency to collapse rather than extend and straighten. The tippet is the thinnest part of the leader that attaches to the fly. It is intended to allow the energy of the cast to dissipate, resulting in a cast that doesn’t crash on the water. The tippet also allows for a less visible connection to the fly. The taper is the section between the butt and tippet that provides a smooth, progressive transfer of energy. A leader with a thick butt tied directly to thin tippet has a tendency to “hinge.”

Leaders are primarily sized by their length and tippet size. So, if you purchase a 9’ 5x leader, it has a tippet size of 5X and its overall length is 9’. As a general rule, longer leaders are advantageous for not only creating more distance between fly line and fly, but for achieving better drifts in “technical” currents. However, they are more difficult to cast and more prone to find overhanging limbs! A shorter leader can allow for more accuracy in tighter areas.

The tippet is sized by its diameter and is indicated by a number followed by an “x.” The bigger the number, the smaller the tippet, so a 6X tippet is considerably smaller than a 2X tippet. Without getting too deep into the history of what now seems a rather antiquated system, it all works off the number 11. If you subtract the tippet size from 11, you get the actual diameter measured in thousandths of an inch. For instance, 6X tippet is .005”. It works in reverse too. If the actual diameter of the monofilament is .007”, the tippet size is 4X: 11-7=4. Pretty weird, huh?

Tippet Spool

You don’t need to know all of that, though. Just know that the tippet size should typically be chosen based on the fly size. Small flies should have small tippets and big flies should have big tippets. Some leader packages will have cross-reference charts on the back indicating which tippet sizes match which fly sizes. Another neat trick is to divide the fly size by 3. So a size #12 fly would best match a size 4X tippet. Could you use a 5X tippet on a #12 fly? Absolutely. This is just a guideline. But the farther you stray from the guideline the more problems you’ll encounter.

In addition to being part of the leader, tippet can be purchased by itself on spools. Tippet material can be pulled from the spool and spliced to the leader with a knot to rebuild or alter the leader. For instance, if you start the day with a 9’ 5X leader and you change flies a few times or break off in a tree, your tippet gets shorter and shorter. You can add tippet from a spool when this happens to build the leader back to its original size.

How Stuff Works: Landing Nets

Variety of Landing Nets

Landing nets are designed to enable anglers to land a fish more easily and safely. They are most beneficial when dealing with larger fish that have a tendency to make one last dart or head shake when you try to grab them, often resulting in the tippet breaking. While in the Smokies, I rarely carry a net because the fish are typically not very large and can be landed by hand with very little trouble, and a net is just one more thing to carry. But I use a net regularly when fishing tailwaters and delayed harvest streams.

Long Handle Carbon Net

Traditionally, nets have been made with a wood frame and cotton netting and that style is still common today. However, wooden frames are more and more frequently being replaced by lighter, carbon frames and rubber is replacing cotton for the netting. The rubber netting has a number of advantages over cotton – the most notable being that it is better on the fish. Cotton netting has a tendency to get caught and tangled in the fins, gills and teeth of the fish and with trout, absorbs and removes some of their protective “slime.” Fly hooks also catch and easily tangle in cotton netting. Rubber netting eliminates all of these problems and holds far less odor than cotton.

Other things to consider when looking for a net are the size and shape. Obviously, if you’re expecting to catch bigger fish you’re going to want a bigger net. A 20-pound striper just won’t fit in a 16 ½” trout net. Landing nets are typically sized by the overall length, including handle, as well as the size of the head (the part that holds the netting). The size of the head should be chosen based on the size of fish you’re pursuing while the overall length (or the handle size) should be chosen based on how you will be pursuing them. For instance, if fishing from a boat, a longer handle may be desirable since it’s more difficult to get the fish close to you. If wading, a long handled net might be too cumbersome to carry all day.

Magnetic Net Holder

If you plan to carry a net with you when wading, there are a number of options that will help keep the net out of the way, yet easy to access when needed. Most every fishing vest or jacket has a D-Ring on the back. The sole purpose of that ring is to clip your net on it. To make it even easier, there are magnetic connectors that include a section of plastic, “pig tail” type cord that allow you to utilize the net while it remains tethered to you. There are also oversized retractors that accomplish the same thing.

Net Holster

Folks who choose to use sling packs or hip packs tend to have trouble finding a suitable location for attaching their net. Attaching it to the pack with a traditional retractor or magnetic connector often leaves it hanging too low or in a location that impedes the casting stroke. I know many who have remedied this by using a type of net “holster” placed on a belt. The net is stored handle down and drawn from the holster when needed.

Like most things in fly fishing, there doesn’t seem to be a “one size fits all” solution to the type of net you use or the method you use to carry it. It’s a matter of finding something that best fits most of your needs and carrying it in the least obtrusive way possible.

How Stuff Works: Fly Lines

For those with more of a spin fishing or bait fishing background, you may be used to casting a weighted lure or live bait with sinkers. You have a reel of monofilament line and when you cast, you propel the weighted lure forward and it carries all of the monofilament line with it.

In fly fishing, we’re using virtually weightless flies, many designed to float on the surface of the water. Even weighted flies that are designed to sink don’t have enough weight to carry themselves any sort of distance. We use the fly line for that. In essence, the fly line replaces the weight of a lure. When spin fishing, a weighted lure carries a weightless line when cast. In fly fishing, a weighted line carries a weightless lure.

Most fly lines will have a core of come sort and a plastic coating. Saltwater lines usually have a more rigid monofilament core, while freshwater lines usually have a softer, suppler Dacron core. When the plastic coating is applied, it is usually done in such a way to achieve a particular taper. The taper is how and where the weight is placed on the line and how it is designed to behave.

A weight forward taper is the most common. If the fly line is 90’ long, which is typical, the first 50’ or so that attaches to the backing and the reel will be thinner and level. Approximately the front 40’ of line will be thicker except for the last few feet where it attaches to the leader. The intention is for the weight to be in the front part of your line to maximize casting efficiency at your most common distances. For longer casts, the thicker, weighted portion “pulls” the thinner, un-weighted portion behind it with a technique called shooting line.

There are variations on this weight forward design for specialty situations. For instance, a bass line may have a shorter but more dramatic taper, where more weight is placed in a smaller area. The purpose of this is to aide in turning over the heavier, more wind resistant flies commonly used in bass fishing. Some of these variations are referred to as ‘shooting heads.”

Fly Line Tapers

A double taper line is becoming less and less popular but is one I still really like for fishing smaller streams like in the Smokies. It has a more gradual taper and it tapers equally from the middle of the line out to each end. This design allows for more delicate, accurate presentations at distances of 40’ and closer, and it roll casts extremely well. It’s also nice because you when you wear out one end of the line, you can turn it around and use the other. It is a disadvantage for distance casting because when you get beyond 40’, you get into the “reverse taper.”

You may also run across level lines, especially at discount type stores. There is no taper to level lines. They can be attractive to the beginner because they are so inexpensive but they cast horribly. Unless you are getting into some specialty techniques, I would avoid level lines altogether.

Most fly lines float. Even when fishing weighted flies in streams, a floating line is most often used because the fly and leader can usually sink enough to get the fly where it needs to be. However, there are sink tip lines available in different weights, where the front part of the fly line will sink to get a fly down deeper and faster. These are more commonly used for streamer fishing in lakes or deep, swift rivers. Full sinking lines are also available but not used very frequently. They allow the entire line to sink but are extremely difficult to cast.

Common Fly Line Weights

Fly lines are sized by a line weight that is designated by a single number like a 4-weight or 9-weight. This is intended to match the same designation on a fly rod, so you would use a 5-weight line on a 5-weight rod. It takes the amount of weight in a 5-weight line to properly flex or “load” a 5-weight rod and make it cast its best. If you used a 2-weight line on a 5-weight rod, there wouldn’t be enough weight to load it and you’d throw your arm out trying to get the line out. If you used an 8-weight line on a 5-weight rod, it would overload it, resulting in a hard, clunky cast that was hard to control. There may be some specialized situations where you may want to over-line or under-line a rod, but 99% of the time, you want to match the line weight to the rod.

You choose what line weight (and rod weight) you need based on what you’re fishing for. For trout, you’re typically casting smaller flies to fish in clear water and trying to achieve delicate presentations. Lighter lines in the 3 to 5-weight range are common. For largemouth bass, you’re probably fishing more stained water and commonly casting bigger, more wind resistant flies. You’ll be able to better accomplish this with 7 to 9-weight lines/rods.  In saltwater, you probably want heavier lines not only for heavier flies, but also to contend with heavier winds.

Early Spring Fishing – Locating Feeding Trout

If you’ve ever fished with me or have read more than two articles in this newsletter, you undoubtedly know how much I emphasize the importance of water temperature when fishing for wild trout. Often in the summer, it can be too warm in many places, causing trout to be lethargic or even migrate to cooler water. In winter, it can be too cold, causing changes in metabolism and a shut down in feeding. In early spring, you’re often fishing right on the edge of good water temperatures. Throughout the day, you may encounter totally different feeding behaviors – from hour to hour and from pool to pool.

Though it’s not quite this exact, 50-degrees is kind of the magic number we’re looking for. When we see water temperatures at or above 50-degrees for the better part of the day, we typically start to see actively feeding fish. This is due to not only the change in metabolism, but also the increase in bug activity. It can be deceiving, though, when we start to have these warmer days but the overnight temperatures are still getting pretty cold. It may be late morning or early afternoon before the water has had time to warm to a “stimulating” temperature.

So forget what your granddad told you about getting to the water at dawn. That’s great advice during the heat of summer, but in early spring, it will usually only give you a lot of casting practice until things heat up later in the day. While there are, of course, variables based mostly on weather, your best fishing this time of year will probably be between 11:00 a.m. and 5:00 p.m. Sleep in, eat a late breakfast, get to the water around 10 so you have some time to gear up, and enjoy your afternoon.

This is also not the best time of year for making that 7-mile hike to a high elevation brook trout stream. With very rare exceptions, your water temperatures are going to be considerably cooler at high elevations. This is the time to focus on lower and mid elevation streams.

The heads of large pools can be great locations for feeding trout

Now that you’re at the right place at the right time, there are other things you want to look for. While slower pools often fish poorly later in the year, they can be great places to fish in early spring, mostly because of the abundance of food. The best hatches, at least in the Smokies, occur in the spring and you can target a lot of feeding fish in these pools. Dry fly fishing can be at its best on early spring afternoons and it’s a great opportunity to find a larger brown trout feeding on the surface. Even if there is not an active hatch, there are plenty of bugs preparing to hatch. Drifting nymphs along the bottom, particularly near the heads of these pools can be very productive.

The other advantage to larger pools this time of year is they typically have less tree canopy and the water gets more direct sunlight. Seeking direct sunlight is counterintuitive to many fishermen, but in the early season, it often means warmer water. And even if the sunlight isn’t significantly warming the water, it is likely stimulating more bug activity, which will in turn, stimulate fish. Still, bright sunlight can have a negative impact on fish and their willingness to feed, so I try to seek out and pay particular attention to the “sweet spots” – good holding water that has a nice mix of sun and shadows.

Finally, when choosing days to fish this time of year, really try to pay attention to the overnight lows more than the daytime highs. Warmer overnights will better maintain those water temperatures we’re looking for. And don’t be afraid to get wet. A warm rain can raise water temperatures and turn fish on quicker than anything this time of year!

 

 

 

 

 

 

 

 

 

Trout Behavior (Part 2)

Understanding How Trout Feed and the Importance of Presentation….

 It has been claimed by many, beginner and expert alike, that Smoky Mountain trout are among the most difficult to catch. Talk to a few Smoky Mountain anglers for any length of time and at some point the statement, “If you can catch them here, you can catch them anywhere!” will certainly be heard. That’s not entirely true. Simply driving a little north to the Clinch will teach you that. Employing Smoky Mountain fishing tactics on that big tailwater may reap rewards in a few areas, but the long, slick waters of the Clinch will require different skills to be consistently successful. Almost every fishery has certain characteristics and little quirks that make it uniquely challenging.

But this much is true… If you are catching fish in the Smokies on a consistent basis and understand why and how you’re catching them, applying those skills to other freestone rivers, such as those in the American West, will put you a step ahead of many anglers. But why? What is it about these little mountain streams that is so challenging?

The first thing is simply the fact that you typically have a significant volume of water in a small space. Rather than water flowing through a broad basin, where current speeds are somewhat consistent and concentrated in long, broad channels; in these small streams, the flow breaks and changes speed dramatically with every boulder it hits. So in many situations, in one fishy run, there may be fifteen different current speeds with which to contend. That may not be a big deal if you understand how that phenomenon can impede drift and you can approach those runs properly, but failure to understand this can convince many an angler that there are no fish in these streams!

I’ve seen a number of VERY good fly fishermen come to the Smokies and get skunked. In most cases it is because they are big river fishermen and they approach these streams in the same way they approach the big rivers they normally fish. That usually entails standing erect at the bottom of a run and making a 40-60 foot, up and across cast to the top of the run. The result is 40-60 feet of line being grabbed by fifteen different current speeds, and an attached fly dragging like RuPaul! All but the smallest and dumbest fish in the Smokies will not tolerate a poor drift, and with the exception of the rare slow pools, there is no way you’re going to be able to cast that much line and be able to control your drift. Executing a good drift in the Smokies is going to require getting closer to the fish.

First, it is important to understand where the fish will be and why. You can find fish in the slow pools but these are among the most difficult to target. Without a defined channel to concentrate food, fish in these pools will be very spread out and often cruising, feeding opportunistically. Unless there is a significant hatch coming off to motivate consistent feeding and reveal fish when they break the surface for a meal, catching them in these environments is going to require a lot of patience, a lot of trial and error, and a lot of plain dumb luck. This is certainly not to say you can’t catch fish in slow pools in “hatchless” situations, but the odds are not with you.

For heavier concentrations of actively feeding fish, you’ll want to be in the riffles and runs where there are clearly defined channels. The stream funnels insects and other food items into these channels, and where you find food, you find fish. And in these food abundant areas, fish are typically “holding,” waiting for the meal to come to them. But because there is so much “stuff” coming through these chutes, from aquatic insects to stream debris, the fish instinctively ignore passing items that don’t look like food. Your imitation dragging through the feeding zone faster than the current because another current is pulling on your fly line, qualifies as something fish will ignore. To control the fly you have to control the line. To control the line in a run with multiple currents, you have to get closer.

To get closer, you’ll want to employ the strategies discussed in Part 1 of this article: dress accordingly, stay low, and be stealthy. The idea is to get into a position where you can use the length of your rod to keep the fly line out of any currents other than the one where your fly is. So you’re keeping the rod high, keeping most, if not all, of the line off the water so that there is very little to impede the drift. By following the fly with your rod tip, you can extend your drift through the run. There are going to be a number of these little feeding zones within a run, so you try to hit one, reposition yourself, hit the next, reposition yourself, and so on.

Check out the photo above – a typical stretch of water in the Smokies. You can easily see the numerous changes in current speed and direction in just this small area. Rather than standing at the bottom right of the photo and casting 40-50 feet to the top left of the photo, our angler is intelligently breaking this stretch into defined sections. He has likely already fished the water below, to his left, and right in front of him. Notice he has his rod high, keeping the line off the current directly in front of him, and allowing the fly to drift nicely in the current breaking around the right of the boulder. Next, he will likely step up to the boulder and fish that large pocket above it. Well done!

The angler in this photo is also doing a good job with a little more line out. Notice he is concealing himself behind a boulder and his rod is help upward, keeping the current lip in front of him from grabbing the line. The line that is on the water is all in the same current speed. Again, well done!

He likely fished the current below that boulder before stepping into that position. It’s all about planning your attack. Determine your targets and carefully place yourself in the proper position before casting to them.

Setting the Hook

Fishermen in the Smokies also miss A LOT of strikes. Some of the misses can be attributed to the fact that trout in the Smokies hit and spit a fly with amazing speed. You can just go on and plan on missing some strikes when you fish here – just like you can plan on getting hung in a few trees – it’s all part of it!

But you can greatly increase your number of hook-ups by implementing the above strategies. While many strikes are missed due to the angler just not being ready or reacting to slowly, just as many are the result of too much line on the water. The more line you have out, the more line you have to move and tighten to set the hook. And when that line has a lot of slack in it, there will be even more delay.

It’s a delicate balance. In most cases, you have to have a little bit of slack in your line to allow your nymph or dry fly to drift without drag. Keeping that slack to an absolute minimum will allow the rod tip to lift and tighten the line on the fish much more quickly and will certainly result in more fish to hand.

Trout Behavior (Part 1)

Understanding a Trout’s Vision and Instincts for a Better Approach…. On numerous occasions guiding clients in the Smoky Mountains, I have been met with a suspicious and doubting eye when I provide certain instruction regarding approaching and presenting the fly to wild mountain trout. The reply is often something like, “Are they really that smart?” No, trout aren’t that smart. They have the brain the size of a pea. But the fact that they aren’t that smart is what allows them to be so good at what they do. Unlike us more “intelligent” humans, trout aren’t distracted by health care reform, college football, paying the mortgage, or who got voted off American Idol last night. Their entire existence is ruled by instinct, and their only real concerns are receiving enough oxygen, eating, and not being eaten! When your life is that simple, it allows you to remain pretty focused.

Think about a simple housefly for a moment. Trying to catch one is difficult. A housefly isn’t smart. It’s not planning out evasive maneuvers in the event of a human attempting to catch it. First I’ll cut right, then I’ll go up, then I’ll get behind the blinds at the window…. It’s pure instinct. Survival. Something we humans have to go through rigorous, repetitive training to achieve.

One of the biggest mistakes anglers make when approaching fish is doing so from upstream. To a trout, a stream is a conveyor belt of food, constantly delivering hatched aquatic insects and terrestrials on the surface and juvenile aquatic insects (nymphs) between the surface and the bottom. Trout aren’t looking down the conveyor belt to see what they’ve missed, they’re looking up the conveyor belt to see what meal is coming next. If the trout see something suspicious at the top of the conveyor belt, like you, they’re going to likely quit feeding until they feel safe again. They may even go hide!

So the trout knows I’m trying to catch him? No! But he’s spooked. Think about a situation you’ve been in where your senses were heightened. Maybe you’re walking alone late at night on a dark street and you hear a strange noise up ahead. Is it the wind? A stray cat? Another person? A serial killer? You don’t know, so what do you do? Do you race up ahead to check it out? Do you ignore it and keep on as if nothing happened? You would probably stop doing what you’re doing and assess the situation. You might even turn around and go the other way. It’s the same thing if something disrupts a trout’s comfort zone while they’re feeding.

Another interesting way to look at it is if you take the dark street scenario described above and insert a thirteen year old rather than an adult. Due to limited life experiences and a feeling of invincibility, the thirteen year old may proceed with less caution, if any at all. Now you know why big (old) fish are harder to catch than small ones!

You’ll be far more successful if you approach the fish from downstream and cast upstream. This puts you behind the feeding fish where you are less likely to be detected. Notice I said less likely. You can still alert fish to your presence by making a lot of commotion through careless wading. When possible, stay out of the water or right on the edge. When you do enter and move through the water, do so quietly and deliberately. Stomping along the stream bottom and/or splashing through the water will produce excessive vibrations, again alerting the fish to possible danger.

You also want to keep a low profile to remain unseen by the fish. So trout have eyes in the back of their heads? No, but they can still see things behind them – to an extent. Trout are predators and prey, and they are blessed with vision that benefits them in both roles. Like humans, they have binocular vision that allows them to see straight ahead underwater. Because of the placement of their eyes, they also have an extended range of peripheral vision, allowing them to see things on either side of them. Since this vision is used to look straight ahead and to each side, there is little distortion and it’s very clear – much like we would see under water.

The cone

But trout also have a cone-shaped field of vision above them that allows them to detect predators from above. Because of the distortion caused by light refracting as it hits the surface of the water, trout are unable to clearly make out objects, so this is used to visually detect movement more than anything else, such as a Kingfisher swooping down to get them. It’s the same as if you were to lie down on the bottom of a swimming pool and look up. You would be able to see objects but they would be so distorted it would be difficult to differentiate between a person and a tree – until that person started to move. However, something that is right on the surface, like a mayfly dun, will be clearer to the trout than something above the surface, like a bird – at least the silhouette will be much more distinct – making this ability effective for feeding on adult insects and terrestrials.

As you’ll notice in the poorly illustrated drawing above, that field of vision does extend a little behind the trout – upward and outward. Everything that makes its way into that cone can be detected by the fish. So, when approaching a trout from behind, how close you are determines whether or not you’re in that cone of vision. Notice however, that a short object can be directly behind the trout and unseen while a tall object would be in the field of vision. This is why many successful Smoky Mountain anglers can be seen crouching or squatting when closely approaching fish. The lower profile keeps them out of the fish’s “window.”

The other thing that should be considered is the type of water you’re fishing. The faster and more broken the water is, the more difficult it will be for the trout to detect you, making it easier for you to get closer to the prey. On the other hand, trout in the slower, flatter runs and pools are going to be able to detect you much more easily and may require you to stay back a little more and put a little more distance on that cast.

In any situation, the more you can conceal yourself, the more successful you will be. Stay low. Wade slowly and quietly. Hide behind rocks and boulders when you can. And for God’s sake, leave the bright orange, hot pink, neon yellow clothing at home. You don’t have to be dressed in full camo with twigs and branches in your hat to catch fish here, but simply dressing in earth tones – browns, olives, khakis, and greys – will go a long way toward not scaring every fish before you even make a cast!

Check back soon to see Part 2 of this series about how trout feed and how to effectively present your fly.

A Matter of Degrees – Understanding Water Temperature

One of the most significant factors that determines how, when, or even IF a trout feeds, is water temperature – at least with wild trout. Stocked trout are raised in hatcheries and fed every day, so they are used to eating every day. Water temperature can impact the way they feed but not nearly to the extent it does a wild trout.

Fishing for stocked trout can still be productive in excessively cold water temperatures

An ideal water temperature for a trout is in the upper 50’s to low 60’s. If you show up at the river, dunk your thermometer in the water, and get a reading of 60-degrees, chances are you’re going to have a pretty good day – assuming you do everything else right. On the other hand, if you do everything exactly right but the water temperature is 38-degrees, you may not even get a strike.

On a broader scale, I think of anything between 50 and 68-degrees to be reasonable. But there are variables. 52-degrees and falling due to a cold front may result in tough fishing. 48-degrees and rising due to a warm front may produce excellent fishing. Fish will probably be sluggish if it’s 68-degrees and rising in a summer drought. But 68-degrees and falling because of a summer rain may really turn them on.

With warmer temperatures, it’s more about the oxygen than anything. Trout need oxygenated water and typically, the warmer the water, the less oxygen. If water temperatures hit 75-degrees for more than a few days in a row, trout can’t survive. They’ll either search out more suitable conditions or die.

A stream thermometer can be a valuable tool when searching for active trout

With excessively cold water, it’s more about metabolism. As a survival mechanism, their metabolism changes when water temperatures get extremely cold and they don’t require as much food. It’s similar to a bear during hibernation. So if you’ve ever tried to get me to take you fishing in the Smokies in January and I talked you out of it, that’s why. I have great gear and am not afraid of getting out in the cold, but the fish just wouldn’t be feeding.

On some extremely fertile rivers, this may not be the case. There may be enough food through the winter to keep the fish feeding. I know I’ve fished some excellent winter hatches in Montana. But the streams of the Smokies are the opposite of fertile. They’re some of the oldest mountains in the world and consequently very acidic and nutrient poor, which means there is just not a lot of food, especially in the winter.

There are a number of things that can influence water temperature, with air temperature being one of the most obvious. In the mountains, air temperature and consequently, water temperature can vary significantly by elevation. For instance, a river at 2000’ elevation may see an air temperature of 85-degrees in July with a water temperature of 68-degrees. But if you go to a stream at 3800’ elevation on that same July day, you may find an air temperature of 75-degrees and a water temperature of 61-degrees. That’s why I typically like to focus on high elevation streams in the middle of the summer.

Of course, the opposite is true early in the season. The high elevation streams may be too cold while the low elevation streams are starting to turn on. I once guided a local gentleman on a high elevation stream in July and we had a very productive day. He called me, frustrated, the following March. He said he’d just been to the same stream I took him to, did everything the same way, but didn’t even get a strike. In July, the water temperature had been 60-degrees on that stream. When he went back in early March, it had been closer to 40-degrees. It matters.

Tree canopy can also have a big impact on water temperature. A bigger, more open river may not be very productive on a late June afternoon. But a smaller, more heavily canopied stream at the exact same elevation might be very productive. It seems pretty obvious when you think about it, but the more direct sunlight that reaches a stream, the warmer the water is going to get.

Time of day is another big factor. A lot of people think you have to be on the water at the crack of dawn to catch fish, which is only sometimes true when you’re talking about stream trout. In the heat of the summer, very early and very late in the day are probably the times when you’ll find the most active fish, because you’re getting slightly cooler water temperatures. However, if you’re fishing in early March or late November, you’ll likely find more active fish in the middle of the day, when water temperatures are slightly warmer. That’s one of the reasons why our peak fishing seasons are in months like May or October. The temperatures are mild pretty much all day, and the fish are active pretty much all day.

This is all very specific to free flowing streams. Tailwaters are totally different animals all together. When a river is dammed to form a lake, they release water from the dam every day to control flooding and to generate electricity. The river that is formed below the dam from these releases is referred to as a tailwater.

Many rivers below large dams maintain nearly constant water temperature all year

The water that they pull from the lake to form the tailwater comes from near the bottom of the lake. Because that water is so deep, it receives no sunlight and is basically insulated by all the water above it. So, the water that comes out of the dam is approximately 50-degrees, regardless of time of day, time of year, or air temperature, which is why that big, wide-open river can support trout. Spring Creeks are very similar because the water source is deep underground, insulated by earth.

How deep the lake is determines how much cold water “storage” it has. That and the volume and frequency of water releases determine how far down river the water stays cold. Your typical East Tennessee tailwater will maintain these temperatures, and support trout, for about 25 miles. So when it comes to tailwaters, you’re always going to have about the same water temperature, making them year round fisheries. With tailwaters, it’s mostly the timing and duration of the water releases that determine when, or even if you can go and how much success you’ll have.

Back to the mountains, water temperature is one of the things that I pay the most attention to when deciding when and where to fish. I’ve been doing this a long time so I just kind of know based on all of the conditions. Until you “just know,” a stream thermometer can be one the most valuable pieces of gear in your bag.
