Chances are some of the trout you’ll see rising this spring will be feeding on emergers just below the surface–mayflies, caddis (at right), or midges that remain an inch or two underwater while beginning to emerge as adults. That’s where your emerger fly should be. To suspend your fly just below the surface, apply some floatant to your entire leader except for the last 3 or 4 inches of tippet. Most of the leader will float, keeping your fly just barely underwater and right where the trout expect to see it.
