Fly Fishing the Sulphur mayfly hatch

The sulphur mayflies are coming off well now and the trout are feeding on both the nymphs and the adult (dun and spinner). A very special friend the late John Snyder, one of the finest brown trout fly fishermen on the east coast, was so successful with the nymphs on this hatch that he would often continue fishing them a hour into the hatch, long after the rest of us had switched to the duns.
If you want to play John’s game use a Murray’s Professor Nymph 14 and fish it upstream dead drift in the deep runs and below the riffles and even dress it with a cream floatant and fish to rising brown trout. This latter ploy is very effective on heavily fished streams.
I actually enjoy flyfishing drys best on the Sulphur hatch and use both Ed Shenk’s Sulphur 16 & 18 and the Murray’s Sulphur Dry 16 & 18 and fish all of these on 6X.
I always watch for feeding trout and go one on one with these fish. However, if I don’t see risers I use the dry flies to cover the water. Remember, the streams are getting lower and the brown trout are wary so use a cautious approach.
My final tip on the sulphur hatch is to stay on the stream until dark in order to cash in on both the duns and spinners.
