The one I have with crappie is about and acre and had no cover other then weeds when I got it. I have added some cedar trees and need more. The pond the crappie didn't spawn in was about 2/3 acre and had a lot of woody cover and had nice bass and big bluegill.

The pond I am building below the crappie pond is 10 acres and I don't even want to attempt to manage crappie. Hopefully I wont get any from upstream it is fed by a wet weather creek and gets some strong flows with no telling how many farm ponds that run into it.
