Catch Fish by Not Fishing
Don't be in a rush to start casting.
by Eric Peper

Several years ago, while watching an ambitious young executive animatedly oversell an idea in a business meeting, a friend of mine smilingly whispered to me, "Enthusiasm is often the last refuge of the ignorant." I've used that line at least 100 times since, generally in a facetious or cynical vein. Yet, it has important implications when applied to fly fishing.

Most of us don't get nearly enough time to fish. (It would probably be safe to say, "None of us.") When we do go fishing, we typically plan for several days and drive for several hours to get to a favorite place. When we get wherever we're going, we nervously rig the rod, rush to the water, take a quick look around, and begin casting. Our success would, in most cases, be greater if we spent the first half hour to an hour not fishing, and often our enthusiasm to begin fishing may be cause for failure.

Example 1: Mid-August, 4 p.m., The Madison River about four miles below Quake Lake, at the upper end of what has been called "the 50-mile riffle." I arrived with rod already rigged, got on waders, and went to the north bank of the river. Several caddis were in the air, and I quickly saw a rise behind a boulder in midstream. I waded into position about 25 feet from the bank. One cast with a number 16 Elk Hair Caddis took the 13-inch rainbow. For a half hour thereafter I experienced an excellent hatch, but no hits, no hookups, and naturally no errors.

It was a hot afternoon, and I went back to the car for some ice water. As I sat on the bank and quenched my thirst, I let my eyes scan over the river to see if I could determine what the fish might be doing. After I'd been there about 20 minutes, I saw a large brown trout slide into a six-foot-long, eight-inch-deep trough less than a foot from the bank and less than six feet from my feet. I watched him quietly sip caddis for about 15 minutes, then I took him by "dapping" an Elk Hair Caddis while holding my nine-foot rod at a point midway in the first section so it wouldn't stick out too far from the bank.

When I stood to play the fish, I spooked two other "good" fish that were feeding in the same close-to-the-bank types of lies within 20 feet of where I'd been sitting. The rest of the evening was a major success. I took several good fish within a 200-foot stretch of river, and I never even entered the river except to play a hooked trout. Twenty minutes of observation had serendipitously led to a discovery of where the fish fed.

Example 2: For a couple of summers I had a wonderful natural laboratory in eastcentral Wisconsin in which to study the Tricorythodes spinner fall and how wild trout fed on it. The location was within a 45-minute drive of my office, and I tried to fish for an hour or so each day that the weather permitted. I located the spot coincidentally while exploring the stream one weekend morning. It was about a half mile below an island where the river formed an estuary below a 100-foot-long riffle as it entered a slow, deep pond-like stretch.

The first morning I fished it, I got there just as the trikes had started to fall to the water. I saw no rises as I reached the pool, but shortly after I got there a good fish rose. I immediately put a cast over it, and the trout never rose again, although I saw both that fish and a couple of others moving through the pool.

The next morning, in similar weather conditions, I arrived a bit earlier. This day I had time to sit on the bank and wait for the spinners to begin falling on the water. As I watched I saw a slight bulge on the water near the far bank. A bit later there was a rise near the same spot. I waited until three good fish were feeding avidly on the spinners before even standing up. Even then, I waited to move until I was sure the fish were continuing to feed. Then I entered the pool, going only far enough into it to cast to the fish I'd selected.


Don't overdo it.

What I discovered, beginning this day and on several days afterward, was that waiting until the fish were feeding hungrily virtually guaranteed success; entering the river and casting before feeding was well underway almost certainly guaranteed failure.

The length of time you need to spend studying the water and its inhabitants, as well as the value you obtain from that time, will likely be inversely related to the amount of time you've spent fishing that location. This past May I spent my first day fishing in Arizona, which was also the first time I'd fished stillwater in several years.

I arrived at a very popular spot on the Mogollon Rim about 8:30 a.m. along with about 100 others, principally bait fisherman. Most people were nervously running about, getting rods rigged, climbing into boats, or casting night crawlers or salmon eggs from the shore. I had a belly boat with me, but a quick check of water temperature (49 degrees) made me less than enthusiastic to use it. I spent a good hour wandering around the shore, watching insects, spotting a few fish, turning over rocks near shore, and digging around in some of the near-shore muck. I hadn't taken a rod from the car, and, in fact, was kind of enjoying my third cup of coffee.

Most folks had gone some distance from the parking area to begin their fishing. At about 10 I spotted a nice location about 75 feet from where I'd parked that would allow a good back cast, so I rigged a rod and wandered over there. I'd found a lot of damselfly nymphs and a few caddis in my earlier meanderings, so I selected a number 10 Peacock-Bodied Nymph with sparse grizzly hackle.

To make a long day's fishing a short story, suffice it to say I aggravated the bait boys to no end. When I quit at about 3 p.m. to have a beer, I'd taken and released over 30 fish. Most had been taken on the nymph, but at least a dozen fell for the little Elk Hair Caddis fished both dry and in the film. The most I'd seen anyone else land was four, though I did share one of my beers with another fly fisherman who'd been out in a belly boat who said he'd taken a dozen on damselfly nymphs. The hour-plus I'd spent in observing the lake and studying its inhabitants had paid far greater dividends than that same amount of time would have if I'd been casting blindly.

On the other hand, I can usually derive enough information about the fishing status on waters with which I am familiar by looking around for 10 or 15 minutes and bouncing the derived data against the information on my mental "hard disk."

What should you look for when you're observing? Key is observing though you're tempted to begin fishing, so watch from the shore, without a rod if that's convenient. Look for places where fish are holding; not where they're passing through, but where they stay. Look for food forms in and on the water. Look for the way the light is hitting the water, and see if fish behave differently when the light changes. Watch for fish to start to feed, watch how they feed, and note what makes them stop feeding. Look in places you wouldn't ordinarily expect to find fish. You're likely to be surprised.

Let me offer one final experience. There's a spot on the Beaverkill, a section at the upper end of the Wagon Tracks pool, that virtually every one of the thousands of anglers who fishes that pool from the south bank each year walks through on his way to the "best" spots. Wagon Tracks is a deep run though most of its length and holds a large number of good fish, yet the spot I'm referring to is only about a foot deep and within 15 feet of the bank. While wet wading one June day I found it has a spring seep, however, and the spring cools a section about as large as a bathtub. Several dozen times, when I've had the very rare luxury of having that stretch to myself, I've watched a good fish move into the "bathtub."

By allowing the fish to get comfortable in the lie, at least a dozen times I've caught it. Were it not for spending time watching the river rather than fishing, I never would have located that tiny, yet consistently productive piece of water!

Note What They're Eating

When you're looking for food forms, be sure you're looking for available food. It only helps a little to locate food on the bottoms of rocks and in streambed mud. Fish will generally be feeding on food that's "in the drift," that is, food that's floating in or on the water. If you do locate mayfly nymphs, a good way to tell if they're ready to hatch is by looking at the color of the wingcase. Typically, nymphs within an hour or so of hatching will have dark, almost black, wingcases.

Try to capture food in the drift with a pocket aquarium net or a small seine made from a section of window-screen material attached to a couple of dowels. Be sure to take your samplings at a couple of different depths.

When you see rising fish, watch carefully to determine whether they are truly feeding on the surface or just below it. A surface-feeding fish, one taking floating insects, will almost always leave a bubble on the surface following a rise. A fish taking below the surface will bulge, but no bubble will remain after the rise.

Match the Easy Meal

Often you'll encounter situations where you'll observe several available surface food forms. As a rule of thumb, a fish will generally feed on the food that is easiest to capture, because, for obvious reasons, the fish needs to take in more energy from feeding than it expends in the act of feeding.

The "easiest" food may be a function of numbers or of size, but it may just as surely be a function of the ease with which the food can be captured. For example, if there are an equal number of mayfly duns and spinners available to the fish, the fish will almost certainly feed on spinners because a spent (dead) spinner cannot escape the rise, while a dun may fly off.

Similarly, a strong wind or a rain condition may thwart the emergence of mayflies or caddis, and the fish may elect to feed on only those insects that have been damaged in emergence. Careful observation during a hatch will show some insects that have emerged with one wing unfolded or with the nymphal shuck still clinging to the emerged body. You can imitate this "stillborn" condition by clipping the wings down on your dry fly and fishing it in the film or by tying dry patterns with a stubby marabou or fur "tail" the color of the nymph body.
