As we end March on the Gunpowder march browns and hendricksons are hatching. However what is most unusual is the fact that sulphurs size 14-16 are hatching alongside them, mainly in the upper sections of the river. The mayflies are being picked off by trout of all sizes from the nymphs in the morning, emergers to the duns by the afternoon. The low flows mean that long leaders and 6-7x tippet are required for presenting a dry fly. Don’t wait until June to fly fish sulphurs this year!
