Again thanks everyone for all of your comments and help. The nice thing is that we will be draining my pond (3/4 of an acre) and will be able to start fresh. As mr Cody stated earlier, I can make the edges 6 to 8 feet deep as needed. I am going to be looking into aeration to add as soon as I get closer to putting water back in the pond. I am thinking about maybe a windmill type of aerator. I think this will be a good experiment to try. Especially if I have all of you guys in here to helpe through!
