Where are the Natural Nymphs?

Harry Murray relies strongly on his Murray's Nymph Leader with its Scientific Anglers Indicators to catch trout on nymphs in the spring.

Many natural nymphs move to the downstream side of the cobblestones in the lower sections of the riffles at this time of the season in preparation of hatching over the next several weeks. Any nymphs dislodged here are swept into the pool downstream where they are easy prey for the trout. A very effective tactic is to fish a nymph such as the Mr. Rapidan Dry size 14 upstream dead drift right below these riffles and into the runs on each side of the riffles. The Murray’s Nymph Leader with its built in Scientific Anglers Indicators is a great help in detecting these strikes.
