Fish are sporactically rising to midges and small mayflies throughout the day, but especially in the mornings and evenings or wherever there is sufficient cover/shade. Griffith's Gnats or tiny mayfly dries (Sparkle Duns, sz 18-20), should be on your mind, but also consider attractors such as Orange Stimulators or even smaller Elk Hair Caddis (sz 16-18).
Fishing conditions remain fantastic for this time of year. Water levels are up slightly but still clear. Water temperatures will likely rise over the course of the week as air temperatures increase, though it should still remain in the mid-60s.
