Fly Fishing Yellowstone - Brown Drake Dun

For the most part, the Brown Drake duns hatch during the evenings. They may
start earlier on days when the skies are covered with dark clouds, but if it is a
clear, bright blue-bird sky, don't count on it. Until I actually observed a dun, I
would continue to fish an imitation of the nymph. If I did spot a dun or fish rising
to the emerging nymphs, I would fish an imitation of the emerger. If I saw quite a
few duns on the water, I would give an imitation of the large dun a try. One
reason to try the dun is the fact that you can see it much better than the
emerger. The emerger floats flush with the surface by its CDC wing. Our Perfect
Fly imitation of the dun floats high in the water.

Presentation:
A presentation that puts your fly in the area of the stream where you can best
see it in the low light conditions may be the best way to go about it.  That is not
difficult to determine out on the water. Some nights when there is a full or nearly
full moon, you can see the dun very well. If it is a very dark night, you may find it
difficult. You may have to rely more on hearing the sound of the strike than
actually seeing a trout take the fly.

We do not suggest wading. I certainly wouldn't suggest it in the Yellowstone
River below the lake unless your were wading only shallow shoals. In the
meadows of the Gibbon and Madison Rivers, I would fish from the banks.
Wading could be very dangerous at nigh. You could step in deeper water very
easily. Heck, I do it during the daytime.
Our "Perfect Fly" Brown Drake Dun. If you wade, don't stick these flies on the fly
patch of your vest. A big brown trout may come up and attack you, trying to get
the fly off your vest.
