Hatches Made Easy:

Sulphur (Ephemerella dorothea) - Nymphs and Emergers

03/30/08

Nymphs:
The crawler nymphs inhibit the riffles and runs of the moderate to slow currents.  
As I mentioned in the previous article, there is not a lot of water in the Great
Smoky Mountains National Park that falls under this category. This type of water
is found in the section of stream that falls on a slow to moderate decline in
elevation as opposed to a steep decent.

Nymph Presentation:
If you have found evidence that Sulphurs exist in a particular area of water, then
you can fish the nymph imitation prior to the hatch near the bottom using a strike
indicator or on the swing. You are better off, if the bottom terrain permits, fishing
a weighted nymph right on the bottom.

Emergers:
These nymphs usually emerge just under or in the surface skim. The water is
usually fairly smooth in the locations the hatch occurs.

Emerger Presentation:
The smooth, slow water areas that the sulphurs hatch in, may  require you to
fish for individual fish that are rising. This is best done using a down and across
presentation. Many anglers call this "technical" fishing. It requires the same type
of presentations sometimes necessary for fly fishing spring creeks or smooth
flowing tailwaters. You may not be able to get very close to trout feeding on
emerging sulphurs. This means a longer cast is necessary. In the slower moving,
smooth water this requires a well presented fly.
