The hatch situation is in transition: sulphurs are still producing but require evening commitment on sunny days, while Cahills, Isos, summer quills, caddis, size 16 Cornutas and scattered stoneflies fill out the summer hatch calendar. Cloudier days give anglers an earlier dry fly window, while bright days push the best action to last light.

Crucially, Costa signals that the greenie weenie hatch (inchworm fall) is officially underway, making this the moment to add inch worms, ants and beetles to the summer dry fly box. Shop news includes a topwater smallmouth tying class with Caleb Rebarchak at the State College location, the All Fins In tournament benefiting Clearwater Conservancy and a fly fishing festival at TCO's Boiling Springs shop in…
