Small Pond, there are flatheads in PA. They are native to the western part of the state(Mississippi drainage) and have been introduce into the Delaware River drainage and possibly Susquehanna drainage as well.
For a number of years my dad's friend raised both CC and trout in the same pond. The CC survived, but their growth rates were hampered. He built a couple new ponds and has since began raising CC in a different pond. The trout now have their own home. There are still a couple of overgrown and insanely smart CC left in his trout pond. They somehow avoid hooks, arrows, nets, bullets, bird shot and every other attempt to kill them. HAHA
