Insects and other foods the trout may be eating:
1.   Blue-winged Olives - mostly Little BWO - Isolated hatches
2.   Giant Black Stoneflies - hatching
3.   Cinnamon Caddis - Mostly Abrams Creek
4    Light Cahills - hatching
5.   Midges - hatching in isolated locations
6.   Little Short-horned Sedges - should hatch randomly for 2-3 months
7.   American March Browns - hatching but randomly in isolated locations
8.   Streamers - matching sculpin, baitfish and small crawfish
9.   Little Yellow Stoneflies - hatching
10. Green Sedges - hatching
11. Little Sister Caddisflies - Mostly Abrams Creek
12. Eastern Pale Evening Duns - starting any day (called Sulfurs by some)

Eastern Pale Evening Dun (Sulphur)

During the hatch, as a general rule, the Eastern Pale Evening Duns stay on the
surface only a very short time. Remember, these mayflies are not going to hatch in
the fast runs and riffles that are most common in the park. They hatch in
moderately flowing water. Usually this is where the decline in the elevation of the
stream is moderate and not very steep.

They usually hatch from early afternoon to the middle of the afternoon but
sometimes as late as 5;00 P.M. Unless it is overcast, the hatch normally only last
about an hour. On cloudy days the hatch seems to last longer.

Dun Presentation:
Upstream or up and across presentations are usually best. It depends on the water.
You cannot get quite as close to the trout in the moderately flowing water as you
can in the fast water. If the surface is not broken you may need to make longer cast
than you normally would. Often the water is smooth or slick. If you get the fly in the
right place with a good drift the trout usually take the dun imitations very
aggressively. The "Perfect Fly" Eastern Pale Evening Dun is an simi-realistic
imitation of the real duns.

You should approach trout feeding in smooth water conditions using a down and
across presentation. We suggest a light, long leader and tippet in this situation.
Leaders should range from ten to twelve feet in length. You may need to use a size
6X or 7X tippet if the water is very smooth. Most often it is not and you can get away
with a shorter, upstream presentation. However, in a few places we have found
these mayflies where the water was smooth. A few places they hatch in
Cataloochee Creek, Little River near Metcalf Bottoms and a few sections of Hazel
Creeks come to mind. There are many more but all in all, they are isolated. Most of
the water in the Smokies is too fast for them to survive in.
