Trout will eat nymphs in any part of the water column. They may focus their feeding just inches under the surface, or they may go low, picking cress bugs off the limestone bedrock. Trout do what they want, no matter what the books and experts say they should.
However . . .
The default location for finding hungry trout is near the bottom but not on it — anywhere from a few inches to a foot off the riverbed, depending on water type. That’s the strike zone. It’s the depth where trout station and hold most of the time, so that’s where they feed on nymphs. Wise trout don’t chase nymphs much, because they refuse to expend more energy than they gain. And if trout aren’t in a rising rhythm to eat dries, expect to find them with their bellies on the riverbed. That means a trout’s mouth is a few inches up. And remember, trout feed above them more than underneath. So by getting the nymphs about a half-foot off the bottom and in the strike zone, you’ll meet them on their own terms most often.
The beauty of contact nymphing (tight line or euro nymphing) is how the guesswork for the angler is gone. Instead of guessing how the nymph is fishing, all the information about the drift is available through contact and sight. With time and skill, we learn to read the water, make the cast and find contact. Then, with that contact, we read the sighter and trust what it’s telling us.
That’s where we are in this series of nine skills. We’ve found contact by seeing the sighter tighten and change. Now trust it. Believe what it’s telling you. The end of the sighter points directly to your flies, and if you are recovering slack — just staying in touch — then the sighter is traveling the same speed as the heaviest thing on your line.
Think about that a little harder. The tippet beyond the sighter slices past the surface currents, down through the mid currents and telegraphs the speed of the attached fly or split shot. You can trust it. And when that sighter slows down, your nymph has reached the strike zone and likely the level of the fish.
How do we know this?
At the (mostly) upstream angles we’re fishing , there’s only one thing that can slow down the sighter. The water in the strike zone is going slower than any other part of the flow. Unbeknownst to many anglers, the water near the bottom is often considerably slower than the water above it. The bottom flow is bumping into rocks and tree parts. It’s slowed down by friction of all kinds, and the difference in speed is often dramatic.
Of course we can’t see the speed of the water below. We can only see and judge the speed of the surface current. But wait! When the nymph falls into the strike zone and the sighter slows, we now know the speed of the strike zone. We also know how deep the rig is. By recognizing the angle of the sighter and how much tippet is in the water, we know exactly what it takes to get the nymph down to the trout’s level.
This. Is. Everything.
To find the strike zone, look for the sighter to downshift. Recognize the moment the sighter slows down. Sometimes the change in speed is undeniable. And sometimes it’s subtle. Either way, trust that you’ve found the strike zone.
This is big knowledge, because once you locate the strike zone for a given lie, locking it in over and over is repeatable.
Even if a group of fish are targeting emergers and feeding higher in the column, it’s a big advantage to find the strike zone first. Those inches off the riverbed are our baseline, and everything else branches off from there.
What Can You Do from the Strike Zone?
Find it, and you can drift through, efficiently presenting nymphs to trout as they most commonly see them. The real nymphs are gliding along with a neutral buoyancy and trying to find the next piece of bottom structure to grab hold of. Real nymphs do not swim and dart around through various parts of the water column very often. They live all their lives near the bottom, until it’s time to emerge. So find that strike zone, recognize its speed and maintain it. Then your nymphs will look as natural as their real counterparts.
However, riding the strike zone at the perfect speed is tough. We’ll dig deeper into how to guide the flies in the next part of this series, but in the meantime, understand that once you find the strike zone, you may choose to match that speed or bring the fly through a little faster while still keeping it in the zone. You may also allow the fly to drop and tick the riverbed for a moment, then lift it into the strike zone again.
We can rig a second, lighter nymph above the point fly too, using the lower offering to find the strike zone and allowing the tag fly (upper) to tease those hungry trout that have their eyes and attention upward.
Use the cushion of water near the bottom as a reference for everything else. Find the strike zone. Even knowing that the downshift hasn’t happened yet tells us about the fly’s position. We know the nymph isn’t riding low yet but it’s somewhere in the middle.
Locate the strike zone, and unlock the mysteries of what’s happening underneath. Know where your nymph is, and stop guessing
