One of the key skills in nymph fishing is getting your flies to the desired depth. The simple answer might seem to be: just use a heavy nymph. But that’s often a mistake. Heavy nymphs drift unnaturally, resembling a stone rather than something alive. While you can catch fish this way, you’ll catch far fewer than if you use smaller, lighter nymphs.
So, how do you get a small nymph down? It’s all about physics. A slim nymph is more hydrodynamic and sinks faster than bulkier nymphs of the same weight. Shape matters. This is why Spanish Perdigons have become so popular—they sink faster than any other nymph.
Tippet diameter also plays a role. The thinner the tippet, the less resistance it creates, allowing the nymph to sink faster. That’s why I use 7X Egor Fluorocarbon. Thin tippet not only improves sink rate but also allows for a better drift. In a current, thick tippet creates tension, which interferes with a natural drift. Thinner tippet reduces this effect, ensuring a more realistic presentation.
Detecting bites is critical in nymph fishing, but it isn’t always easy. If you’re a beginner, or if the trout are particularly active, or you’re fishing very fast water, 'feeling the bite' is the best method. Keep light tension on your leader, and when a fish takes the nymph, you’ll feel the “tap” in your rod tip or hand. At this moment, set the hook with a soft but quick reaction.
However, tensioning the leader to feel bites can interfere with the drift, and in pressured waters, trout may refuse your nymph. For the next level, focus on 'visual bite detection'. Use small nymphs, cast upstream, and follow the drift with a slight curve in your leader. This maintains contact with the nymph without pulling it. Watch the sighter carefully—any subtle movement (often upstream) could indicate a bite. React quickly but softly with a short, fast hook set. This technique requires focus and practice, but once mastered, it’s incredibly effective and rewarding.
