Fly Fishing Yellowstone - Gray Drake Spinner
The Gray Drake spinners are the most important part of the hatch and as far as
dry fly fishing is concerned, it is the only important part of the game. The duns
do not get into the water unless they accidentally fall in or get blown in the
water. The nymphs crawl out of the water to hatch.
The gray drake hatch and spinner fall occur at different times depending on the
particular stream. On the Firehole River, for example, it normally occurs towards
the end of June to the first week or two in July. The spinners fall can occur
anytime from about the middle of the afternoon until dark. It doesn't last a long
time but is usually fairly heavy, depending on the stream, of course. There is a
good hatch on the Madison River, Gibbon River, Yellowstone River, Slough
Creek, Lamar River, and the Lewis and lower Snake Rivers in the park. The
Madison River hatch occurs about the last week of June.
When the female spinner lays her eggs, she usually flutters over the surface of
the water. Once the egg laying is complete, the female falls spent into the water
and dies. The water is normally smooth where the gray drake spinner fall
occurs. This means you may need to use a longer, lighter tippets and make
some very good presentations to the trout feeding on them.
Most of the time we make a down or down and across stream presentation.
However, the important thing is to get the fly where you see the egg laying
activity occurring. It is very difficult to see the spinner fly in the low light. Watch
your line and leader very carefully to detect takes. The trout just sip the fly. You
want see a splashy rise.
