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 - (called Sulfurs by some)
13. Sulphurs - hatching in isolated areas
14. Golden Stonefly - hatching
15. Little Green Stonefly - hatching

Golden Stoneflies - Nymph:
The Golden Stonefly lives a long time for an aquatic insect. The nymphs take from
two to three years to mature. As I said in yesterday's article, there are several
different species and genera in Great Smoky Mountains National Park. These are
the ones known to exist in the park and I don't doubt that there are more.

Acroneuria abnormis  
Acroneuria arida
Acroneuria carolinensis
Acroneuria filicis
Acroneuria frisoni
Acroneuria perplexa
Acroneuria petersi
Agnetina capitata
Attaneuria ruralis

Like most all stonefly nymphs, the Golden Stoneflies crawl out of the water to hatch.
They move from their normal fast water habitat to slower moving water before they
proceed to crawl out of the water. Usually they crawl out on the banks but it can be
a large rock protruding out of the water or even a limb or log. The trout are very
aware of this movement. They have a perfect opportunity to eat them when they are
migrating to the banks. They tend to feed on them along the banks when the hatch
starts. That is the easiest way for the trout to intercept them.  

You can fish Golden Stonefly nymph imitations any time during the year when they
are not hatching but your odds of catching trout are not near as good as they are
just prior to the stonefly hatch.

Nymph Presentation:
The best way to fish a stonefly nymph imitation during times when they are not
hatching is to fish the runs and riffles using the "high stickin" method. Fish the
stonefly nymph just like you would a generic or attractor type nymph when you are
searching for trout in a "no hatch to match" situation.

The Golden Stonefly hatch occurs very late in the day and into the evening. You
should start fishing the nymph imitation about an hour before dark. You want to
simulate the migrating behavior with you nymph imitation. That means you want to
bring the fly out of the fast water runs and riffles all the way to the bank.

You should stay away from the banks when it is possible to do so to prevent
spooking shallow feeding trout along the banks. If the trees prevent this, and you
are wading, I suggest you use a down and across presentation allowing the fly to
swing from the runs and riffles all the way to the bank. This is best done using a
reach cast, reaching out towards the center of the stream, and then slowly swinging
the fly across to the opposite side all the way to the bank.

You will need to add a lot more weight to the fly to keep in on the bottom than you
normally would. If your fly stays in the very fast water and there is no moderate to
slow moving water near the banks, then you are fishing in the wrong type of place.
You want to select areas where there is at least a small area of moderate to slow
moving water along the bank and fast moving runs and riffles out in the stream. The
fly should stay on the bottom, not mid-depth or near the surface.
