Your pond looks very familiar!!! Is it located just outside of Smithville??? It's late, and I'm probably hallucinating, but the little jetty on the east side reminds me of a pond that is (was??) owned by a former colleague of mine who is a biologist with the Cons. Dept. I know he was thinking of selling it. If it is, then I think you have inherited a trophy bluegill fishery. Maybe it is a small world, afterall. Or maybe I've seen too many ponds and need a new hobby.
Anyway, there are a couple of good foresters with the state that can help you with your tree selection for this area. In fact, one of them has a pretty good plan for pond-type applications. His name is Phil Sneed and he works out of the Chillicothe office. I don't know if you're in his assigned counties, but I'm sure he would give you the information you need. I can't remember the phone number to that office, but I am 100% certain that he works out of the Chillicothe office. He has a really good Powerpoint presentation on trees and ponds (types to choose, distances, etc).
Welcome to Pond Boss and congrats on your new pond.
