Current Conditions In The Smokies
I doubt I have to remind anyone living in the Southeast that weather is still in the hot
summertime mode. The recent break in hot daytime temperatures was great but
much more shorter lived than forecast. It will again be in the low nineties, even in
Gatlinburg at 1600-1800 feet elevation, for most of this week.. The water levels are
back to their normal low levels for this time of year, and if fact are probably lower
than average. While I enjoy fishing low water, many anglers don't. It's a little more
difficult to catch trout.

What is in the forecast this coming Labor Day weekend is anyone's guess
depending on what the newest tropical development ends up doing. I'm not referring
to Danielle or Earl. I am referring to one yet to develop that may not follow the same
course of the last few. Maybe that is what we need to break the hot cycle - heavy
rain from a hurricane but on second thought, that can be good or very bad. On third
thought, I will be happy with what Mother Nature has in store for us.

You should still be able to catch plenty of brook trout in the high elevations. You
also may do well in the mid-elevations as long as you are fishing early in the
mornings. Our "Perfect Fly" business is staying very busy but it is mostly coming
from the Western States or those planning trips to go there.

Mahogany Dun - Nymphs
The Mahogany Dun nymphs are crawler nymphs that prefer slow to moderate water
not fast water. They usually stay in the deeper pockets and pools in the streams of
the Smokies but when they get ready to hatch, they move into shallow water usually
near the banks or tail ends of pools. They can be found in very shallow water at this
time around the margins of runs and riffles in pocket water as well as small pockets
against the banks and shallow pockets behind rocks and boulders. You can catch
trout year-round on these nymphs because crawler nymphs can't hide near as well
as the clingers. However, the most effective time to use an imitation of them is just
prior to the hatch.

You can use a an upstream or an up and across presentation, with or without a
strike indicator depending upon the water conditions and your preference in most
situations. However, there are places you may want to use a downstream
presentation. The trout will spook easily when they are feeding on nymphs in
shallow water. Use lighter, longer leaders and tippet than you normally use.

You may want to use added weight to get the fly down near the bottom but most of
the time, the fly will work great without any added weight because the nymphs tend
to stay in shallow water. I will mention again, that you don't want to fish this nymph in
the fast water of the runs and riffles like you would a traditional generic nymph in
the Smokies. That isn't where the Mahogany Dun nymphs hatch. You want to fish
them in the areas described above.
