A trout eats about twenty percent of his diet from the river�s surface, and eighty percent from beneath its surface. As anglers in pursuit of trout, more often than not, this means that we need to get down and dirty to find our quarry. Bead head nymphs are the most popular as well as the most effective way to do this. Utilizing an incredibly fast sink rate for such a tiny fly it gets near the bottom where trout would expect to find it. These nymphs are most often tied with counter bored brass or tungsten beads. Just as our friends across the pond discovered long ago, these flies are fished effectively in tandem, with some techniques utilizing more than two flies, like Czech nymphing. Be sure to have a box full of these weighted flies for your next day on the water to insure success.
