Have you been to Lake Oneida or Thorn Run near Butler? I had about an hour on Lake Oneida last weekend and looks promising. Saw some big fish jumping but couldn't land anything. I was there in the afternoon and pretty sure I should have been there at Dawn to have better luck. The WCO I ran into told me that the Carp have moved into the shallows at Thorn Run and thought they'd be pretty receptive to some nymphs thrown at them...
What time of day do you normally go? I live about 10-15 minutes from you so we should meet up some time. Not sure about this Sunday but it's still a maybe...
