Last spring, we published a short piece titled Nymphing: Get More Hookups, which focused on increasing encounters with fish by knowing when to set the hook while nymphing. By leveraging the tip provided here, the hope is you can even further add to the number of hookups you're producing not by modifying the strategy but simply by changing what you do once your drift is done, or so you thought.
Traditional nymphing focuses on dead drifting. Casting, mending and so on to insure that your fly is floating downstream just as it would if it wasn't tied to your leader. The reason is simple: this is what real nymphs do, so that's what we want our nymph flies to do if we expect them to fool fish.
But nymphs do more than that. They swim. Some nymphs are good swimmers, while others are lousy at it. Some swim to seek shelter after becoming dislodged from rocks, while others may swim to burrow in sand or silt. The most common reason that nymphs swim, however, is to ascend to the surface for emergence.
