Spotting Fish

In some fly fishing scenarios, spotting fish is absolutely critical for success.  Fishing the saltwater flats for bonefish, redfish, tarpon, etc. or the freshwater mud flats for carp will provide little more than casting practice if you can’t see the fish.  In other scenarios, such as fishing a mountain trout stream, you can tell where fish should be by reading the water, and you can catch a lot of fish just by fishing likely spots.  But even when fishing trout streams, the ability to spot fish in the water can sometimes allow you to locate and target larger fish.  In the fall, this is particularly relevant in the Smokies as large brown trout begin moving into flatter, shallower water preparing to spawn.

Spotting fish can be difficult to learn and there is no substitute for years of experience and practice, but there are a few things that can help you get started.  The best place to start is with a pair of polarized sunglasses.  The next thing to understand is how trout see, because as you seek out vantage points from which to spot fish, you want to avoid spooking the fish in the process.  Here is an article on trout behavior that goes into a little more detail. Now we’re ready to go spot some fish.

Start by looking for fish in slower water.  The more broken the surface is, the more difficult it will be to see through it. If possible, try to find a higher vantage point from which to look.  This will greatly reduce the amount of light refraction from the water’s surface.  Just remember that the higher up you get, the easier it will be for fish to pick up your movement.  Avoid standing erect on a large boulder, as your silhouette will be far more pronounced.  A high bank with a wooded backdrop is ideal, but you’ll still want to keep your movements slow and minimal.  If you are on a large rock above a pool, get on your belly and peek over the edge. Remember the old westerns where the Indians were looking off the rocky bluffs about to attack the wagon train? That’s the idea.

Now that you’re in position, take your time.  It’s extremely rare that you’re going to step up to a pool and immediately see a 27” brown trout.  You have to methodically scan the pool.  Start by reading the water and looking for fish where they should be.  Look for obvious feeding areas in and around current lanes and foam lines.  Look for areas with obvious cover under and around big rocks and/or fallen trees.  They blend in REALLY well, so look long and hard and train your eye to look through the water rather than at it.

It’s hard.  You’ll spot plenty of fish that turn out to be rocks or pieces of wood.  I once spent 15 minutes casting to a plastic grocery bag hung on an underwater limb. It had the exact shape and movement of a trout!  I was in the water and my buddy was above me, watching from a bridge.  We were both certain it was a fish!

Movement and shape really are the best giveaways and that’s why it’s so important to take your time and give long looks to those likely spots.  You may not see anything at first, then you see a little movement and suddenly the fish is visible.  And once you spot one, you often begin to notice others around him.  Watching the actual stream bottom, especially on sunnier days, can be helpful too.  The movement that you often detect is the shadow of the fish.

Another thing to look for is a flash near the stream bottom.  The eyes of a trout are positioned in such a way that they look slightly upward.  When feeding on nymphs on the bottom, the trout has to angle his body to see below and will often “twist” his body when he eats the nymph.  When this occurs, his white belly reflects light and produces a flash.  This is always helpful when looking for fish, but especially in faster water.

All of this is easier the more familiar you are with the stream bottom.  If you have a favorite pool, maybe one where you spooked a big fish before, keep going back there and looking.  You will inevitably begin memorizing the stream bottom and will more quickly and easily be able to differentiate between rocks and fish. Again, it’s not easy and it takes time but like most things, the more you practice, the better you’ll get.

So, you’re starting to spot some fish… now what?  Don’t just jump in and start casting the second you see a nice one.  Keep watching.  What is the fish doing?  If you see a big fish just hugging the bottom, he’s not feeding and you’re wasting your time casting to him.  But good news… you found a big fish.  You might come back closer to dawn or dusk when he is more likely to be feeding.

If you spot a fish up in the water column, he’s likely feeding.  Keep watching him.  Is he looking up?  Does he consistently feed to his right?  Is he staying in one place or is he systematically rotating to different locations within the pool?  Pay attention to all of these things and then you can plan your attack.  Sometimes with big fish, you’re only going to get one shot and you want to make it count.

How much time you spend looking depends on you.  I know guys that do little more than target big brown trout, and they spend far more time watching water than they do fishing.  For me, it depends on where I’m fishing and the conditions.  If I’m fishing pocket water on a high country brook trout stream, I’m not going to spend much time, if any, looking for big fish. I’m going to cover a lot of water and hit the likely spots.  If I’m fishing a big pool on a brown trout river, I’m going to spend at least a few minutes looking before I jump in.  If I’m fishing that same big pool in late fall, I’m going to look a lot more thoroughly!

Legends of the Fall – Hunting Big Brown Trout

Brown Trout Smoky MountainsIt’s the time of year when certain folks seem to be whispering more at the fly shop. They huddle in corners and peek over their shoulders before saying too much. They’re talking about brown trout. Big ones. Somebody mentioned seeing a decent one around Metcalf Bottoms – about 18-inches. A younger guy innocently asked, “Since when did we start referring to 18-inch browns as just ‘decent’?” The older guy replied with a grin, “October.”

Many anglers purely think of the Smokies as a place where you catch wild trout in a pretty place. But as a whole, you don’t expect to catch particularly big trout. After all, rainbows rarely exceed 15-inches and brook trout rarely get any bigger than 10-inches in the Smokies. They’re both almost exclusively bug eaters, and after 3-5 years, they simply can’t support their weight with the bugs available, and they die. But when brown trout reach about 8 or 9-inches, they begin eating minnows, and crayfish, and mice, and birds, and small rainbows. They live 10-15 years and reach lengths of 30-inches in the Smokies!

Fish that size don’t get caught often. Brown trout only live in a handful of rivers in the Smokies to begin with. They’re extremely cagey and for much of the year, they do most of their feeding at night – it’s illegal to fish the park at night. So, outside of the occasional big brown caught at dusk, or dawn, or after a good rain, we don’t get a lot of good shots at these guys. Until late fall.

Brown trout tend to make their spawning runs after the fall foliage has turned colors but before the last leaves have fallen. In the Smokies, that’s usually late October or early November. They typically move to shallower, more visible areas of the stream and are spotted by far more fishermen then. When they’re actually on the nest (or redd), we leave them alone. Not only is it just bad ethics, but they have other things on their mind than food at that time. But in the weeks leading up to the spawn and in the weeks to follow, their appetites are enormous!

In the weeks leading up to the spawn, they’re on the move searching for suitable nesting areas, often. This is when many fishermen are hoping to get their shot at a trophy. A number of folks have booked me during this time, thinking a seasoned fly fishing guide will be their ticket to success. While I can certainly help locate the fish, there is a whole lot that has to go right to catch him. It’s not just having the right fly at some secret honey hole!

Most people aren’t willing to put in the time it takes to catch one of these fish. Unless you’re just going to depend on luck, you have to trade fishing time for looking time. You may not spot one at the first place, or second or third… And once you do spot one, you’re not done looking. You have to watch him for a while to figure out his pattern: how he’s feeding, where he’s feeding, when he’s feeding, IF he’s feeding. You then may have to spend a pain-staking amount of time sneaking into a position where you can cast to him without spooking him.

Assuming everything has gone your way up to this point, you may only have one shot at him. A bad cast will kill the deal. And if he does eat and you do hook him, you’re problems have just begun. Now you have to fight a 25-inch trout in the fast, rocky waters of the Smokies! But it’s all worth it when it does come together and you become one of the lucky few. It’s the stuff legends are made of.

How Stuff Works: Polarized Glasses

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. 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.

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. They may opt not to wear them at all on overcast days or in shade. Polarized sunglasses do protect your eyes and reduce eyestrain in bright conditions. But they have greater importance when it comes to tactical applications.

Light usually scatters in all directions. But when it’s reflected from flat surfaces, it becomes polarized. It travels 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.

Water has highly reflective properties and 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. The chemical filter on the lenses of polarized sunglasses absorbs 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 many anglers expect, this technology does not create “magic fish-seeing glasses!” Fish don’t suddenly appear when you put on polarized glasses. But seeing through the water will definitely help you spot fish. However, there are two other more consistent benefits you will receive from polarized glasses. They’ll help see your dry fly on the surface. And they’ll improve your 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. 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. Dark lenses in low light can offset 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. These are not good choices for sunny conditions on open water.

Do you plan to fish in a variety of different light conditions? You may want 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.

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 for prescription glasses.

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, fitover” sunglasses are worn right over your regular eyeglasses.
