There are still Callibaetis around however the fish aren't keying into them like it was a month ago. Expect a little window each day to fish the Dries and to be using a lot more sub-surface stuff. Stripping in buggers, wind drifting callibaetis nymphs, and Chirnomid fishing are all good alternatives. East should pick up a little bit when weather gets a little cooler and fish move in closer to the shallows.
