Fly Selection and Presentation
(This is a re-run from a previous article)
Last week I received a call from a gentlemen from Ohio who was planning a week's fishing
trip to the Smokies for himself and some of his friends. He was requesting information on
where to fish and what to use, etc. During the discussion he revealed that he and his friends
didn't mind long hikes but wouldn't be camping. He had reviewed and was highly
complimentary of this website along with our Perfect Fly site.

When the subject got around to flies, he said he was a little confused because he was
finding lots of information indicating that all he really needed was Parachute Adams and
Hare's Ear Nymphs. The guy obviously had fished for trout before. In response to looking at
our Perfect Fly pages, he asked, "isn't a nymph a nymph" and "Do I really need the
specialized nymphs for the Smokies" you show on your recommended fly list, he asked.
Before I could answer, another phone started ringing and he had to excuse himself for a
couple of minutes.

When he returned, he apologised and explained he was at the hospital working. When I
asked what he did, he replied that he was a brain surgeon, except he said it using the
correct name. That told me he wasn't exactly unfamiliar with biology or bugs, even though
they were not the aquatic type. With that in mind, I answered his question by asking him a
question. I asked, "Which do you think a trout can see the best, a nymph under the water or
a dun floating on the surface of the water"? He quickly replied that the trout could see the
nymph the best because the only thing it could see about a fly on the surface would be the
parts that protruded below the surface.

It surprised me that he knew the correct answer. Now I don't want to get technical, at least
not for now, but basically, if the fly isn't very close to and directly above the trout, the only
thing the trout could see would be the body parts of the dun that extended below the surface
of the water. The doctor was correct. A trout can see a nymph under the water far better
than a dun on the surface of the water. This is true even if the dun is within the trout's
window of vision. Remember, the diameter of the window of vision the trout views the world
outside of the water is only 2.26 times the depth of water the trout is in.

A trout can see a nymph underwater at a far greater distance than a dun on the surface of
the water. Again, the dun must be almost directly overhead for it to see any part of the dun
that is above the surface. In addition, the water's surface must be smooth within that small
window. I'll get into exactly how the trout views both in the near future but for now, I think
anyone with common sense and a very basic understanding of how fish see objects out of
the water would agree that a trout can see a nymph far better than a dun floating on the
surface. That isn't speculation. That's a fact,
