Hatches Made Easy:

Little Yellow Stoneflies (Perlodidae and Peltoperlidae Family) -
Presenting Imitations of the Nymph

04/04/08









All of the species of these two families of stoneflies live in fast water. They must
have fast flowing, clean water to survive. Prior to the hatch, the Little Yellow
Stoneflies will move along the bottom from their fast water habitat to the banks to
hatch. Some of them crawl up on stones that protrude out of the water to hatch
but the majority use the banks. Just as soon as they get out of water, they shed
their shucks and fly away. The best chance the trout have to eat them is during
this migration prior to the hatch.  
Often, the trout will actually intercept them
along the banks.
These different species of Little Yellow Stoneflies hatch at different times of the
day depending on which species. Most of the Yellow Sallies, or species of the
isoperia genus, hatch in the afternoons. The warmer the weather, the later the
hatch. However, the nymphs will crawl to the banks throughout the day. The later
in the day, the better the fishing usually is, but you can take trout imitating the
migrating nymph anytime during the day.  
If you walk up to the bank and cast or if you walk up to the bank and wade into
the water,
you may have spooked the trout you are trying to catch. Where
the trees and bushes allow, you should first cast to the banks from a short
distance away from the banks. Bring the nymph on the bottom all the way back
to the bank. Remember, the trout do not have to see you to spook. If you are not
careful, they can hear you walking on the bank close to the water through their
lateral line. Ease up to the stream as quietly as possible without kicking rocks,
etc. When you do get in the water, wade away from the bank about a rods length
and fish the nymph down and across allowing the nymph to swing back to the
bank. This will work much better than a up stream cast. Continue to move
downstream a foot or two each cast covering all of water along the bank. If you
cast out a few feet, say ten or fifteen feet using a reach cast that ends with your
rod pointing towards mid-stream, you can slowly swing the rod back in the
opposite direction pointing it towards the bank.
This will swing the fly from
several feet out in the stream all the way to the bank
. In other words you
can cover approximately twenty to thirty feet of water each cast. Of course, this
changes with the particular stream and stream composition. If there is a run near
the bank, you may only need to swing the fly a few feet.
You will need to make longer cast than you are probably used to making in the
Smokies. You need to keep the fly twenty feet or more away from you depending
on the water. In shallow water you may need to keep the fly thirty feet or more
from you to keep from spooking the trout. Remember, the trout will be facing you
when you fish downstream.
Make sure you keep the fly on the bottom. If it is swinging up off the bottom
mid depth or near the surface, you are not going to catch many fish. Weight it
down and keep it right on the bottom. When you pick it up slightly off the bottom,
the fly will swing towards the bank a few inches. Let it get back on the bottom
before you lift the rod again.
