Insects and other foods the trout may be eating:
1. Blue-winged Olives - mostly Little BWO - Isolated hatches
2. Giant Black Stoneflies - starting any day, nymphs active
3. Hendricksons - may have ended
4. Cinnamon Caddis - Mostly Abrams Creek
5 Light Cahills - hatching
6. Midges - hatching in isolated locations
7. Little Short-horned Sedges - should hatch randomly for 2-3 months
8. American March Browns - hatching but randomly in isolated locations
9. Streamers - matching sculpin, baitfish and small crawfish
10. Little Yellow Stoneflies - hatching
11. Eastern Green Drakes - should be starting in Abrams Creek
12. Green Sedges - hatching
Light Cahill - Emergers and Duns
The Light Cahill nymphs emerge in the more moderate to slow moving water that is
very near the fast water they live in during their one year life cycle. They emerge in
the surface skim.
They can begin hatching in the early afternoon but the warmer it gets, the later in
the day they hatch. On clear, very warm days the hatch occurs very late, near
sunset. The emerger stage of the hatch is a very short one. These nymphs change
into a dun in a relatively short time.
Emerger imitations work best if they are presented in the current seams at the
edges of the fast water using short up and across presentations. They should float
in the surface skim.
The Light Cahill duns don't spend much time on the surface of the water. The
warmer the weather, the less time they spend. Their wings dry fast and they depart
the water within seconds from the time they hatch. Theses mayflies hatch when the
trout's metabolism is near its peak and the trout don't waste any time eating them.
The trout usually take the Light Cahill dun imitations readily.
You should present your dun imitation in the current seams that concentrate
the surface flow near the ends of the fast water current seams. Short upstream or
slightly up and across cast work well for this. Keep your rod high and most of you fly
line off the water to prevent drag. The idea is to make short cast and cover a lot of
water fast as you move upstream. Hit the most likely seams and keep moving. You
will rarely find a heavy concentration of these mayflies.
