Sulphur Dun Spinner

Sulphur Dun Spinner:

Sulphur spinner falls are consistent with the hatch, a large hatch will produce a large spinner fall. Depending on the water temperature, the Sulphur Duns mate in the late afternoon. On bright, clear days the spinner fall will occur very late in the day just before dark. If it is especially hot day, the spinner fall may not occur until after dark when the water has cooled somewhat. However, it is usually not productive to fish with the spinner after dark.

The females while flying high over slow moving waters like riffles, slow runs or eddies, where they hatch from, will drop their eggs. The females, unlike the males, will drop dead in the water and they tend to collect at the ends of riffle, or the heads of pools or the eddies.

Spinner Presentation:

A down or down and across presentation of the "Perfect Fly" Sulphur Spinner pattern is the presentation of choice. This will allow you to present the fly over the target slow moving water. As a result, the feeding trout will see and attack the fly prior to seeing you or the leader or tippet.

In the situation of smooth flowing, clear water; use a long leader up to 12 feet in length in combination with a 6X or 7X tippet.

How can you be certain that there is a spinner fall? The answer is that you may not see them so it is advisable to use a net to skim the surface of the water. However, if you do not have a net, fish as if the spinners are there because they probably are if a big hatch has taken place that day.
