Thanks for all of the replies
I've done more recon ( fishing) have caught a wide variety of bass from 2-6 lbs, put out bobber and worms couldn't keep the bluegill off my hook 3" to 7 inches. The former owner never stocked bluegill so I assume someone else put them in. Since the first trip every bass I have caught has looked very healthy so I am going to assume for now that the pond has a healthy balance of forage for the bass. I'll spend the winter reading and learning how to take care of my new toy.
