surface hanging just below the surface skim. There they shed their nymphal shuck and
float in the surface skim. It doesn’t take them long to dry their wings and they usually drift
only a short distance before flying away. The hatches usually start occurring just before
darkness approaches and continues into the early part of the night. The hatch normally
last for just a few days in any one location but moves upstream to higher elevations as
the water warms, but this depends greatly on the particular stream.
Presentation:
When fishing the Perfect Fly brown drake nymph imitation just prior to a hatch, you
should try to imitate the erratic actions of the nymphs. You should weight the tippet down
just above the fly a few inches, and then slowly strip the line in small short darts across
the stream bottom.
At times other than just a few days before a hatch starts, you may find fishing the nymph
is not all that productive, that is unless you fish during the evenings. Fished in the
evenings, when the nymphs come out of their burrows to feed, It can produce some
large trout, especially large brown trout. Just don’t expect fast action. You probably want
catch a lot of trout using this approach; however, if you fish the nymph just prior to a
hatch, it can be very productive. The trout probably eat far more emerging nymphs than
they do duns and spinners combined.
