Hatches Made Easy:

Eastern Green Drakes (Ephemera guttulata) - Emergers and Duns

04/08/08

Emergers:
When the nymphs swim to the surface where they shed their shuck to emerge,
trout sometimes become selective to the hatch, depending on what other insects
are available at the time. This emergence is an off and on occurrence that last
throughout the day and therefore, is not usually concentrated.

Emerger Presentation:
Imitations of the emergers can be fished with a swimming action from the bottom
to the surface during the period of a hatch. This is usually done with a slightly
weighted fly or in slow moving water using an un-weighted wet fly. Fish the
imitation down and across on the swing. I recommend at least an eight-foot
leader with a two, foot long size 4X tippet.

Duns:
Trout readily take the duns during the time they are drying their wings to depart
the water. They leave the water fairly slowly and fly to nearby trees where they
usually hang around for about three days before molting. The idea time to catch
the hatch is the first day or two after it starts. Sometimes the trout get full of the
big mayflies and become hard to catch even though the hatch is in peak
progress. I do not know that this happens in Abrams. I do not know the extent of
the Green Drakes in the stream. We have taken samples and have found the
nymphs, but it is difficult to measure the amount of burrowing nymphs present
without an extensive undertaking.   

Dun Presentation:
In most cases the upstream approach should be used. In the faster moving
water of Abrams you should concentrate on presenting the imitations in areas of
slower moving water such as eddies, pockets and the head of pools as opposed
to fishing the fast water of the ripples and runs. In the slower moving water of the
spring creek section of Abrams, a down and across stream presentation may be
required. In this case longer leaders of eight to ten feet long with two or three,
foot long tippets, size 5x or 6x, may be required. It is in other spring creeks we
have fished that are similar to the spring creek section of Abrams. I am referring
to the spring creek water as the water above the bridge at the Abrams Falls
parking lot.
