My man....we need to talk!......you say you are in north GA, and want to back up 100 acres of water??? Please let me ask a couple of questions, if I may. First, how long have you studied pond and lake construction? How good are you at looking at land topagraphy and topo maps? I get a lot of people in this area who ask me for help in their lake or pond project, and I would love to talk with you and help you in any way that I can if you want.
