Q.Freshwater Trout & Hatches
When is the sulphur hatch on Eastern trout streams?
A.
The sulphur hatch (Ephemerella mayflies) typically runs late May through June on Eastern trout streams, with peak emergence in the first two weeks of June. Sulphurs hatch in the late afternoon and evening, with spinner falls following at dusk. The hatch is one of the most predictable and productive of the year.
Use #14-18 sulphur dun patterns during emergence and rusty spinner patterns at dusk. Hatch calendar pages cover sulphur timing on specific rivers.
