The South Holston is starting to produce the beginnings of its famous sulpher hatch. Today the hatch is limited in both density and location but it's beginning and with the upcoming warm weather we're only going to see it improve. Morning nymphing can be very good to great by using a size 16 pheasant tail and a size 18 Master Sulpher Nymph below it. Don't forget the size 16 & 18 copper johns either. In the afternoon switch over to an emerger pattern or a soft hackle. By 2pm you should be able to fish dry flies consistently. Stick to dry fly patterns that have a narrow profile like a CDC Comparandum Sulpher. Size 16 is best, but the 18's will sometimes fool those larger and more wary trout. Have a great trip and don't forget to give us a call, even for a wade trip.
