The system seems to be in the same shape today as yesterday morning with a slight drop in water temperature. We had another cool night that really felt like Fall. There was some hatching during the day yesterday but it seemed scattered and light. Olives are still making up the bulk of the mayflies hatching but we have seen some oddball sulphurs still out there. The cooler weather should bring the fall isonychias and heptagenia flies. We have noticed an increase in caddis activity – definitely a sign of Fall!
