Yikes! $70k! I better not push anywhere near half that. My guy told me at the beginning that, as an average/rule of thumb, an average pond will come in complete at $5k - 7k per acre, m/l. He is very familiar with the land in my area and felt confident at the low side of this range. My advantage: major clay at 3 - 5 feet below natural grade, surrounding well records (I pulled them fromt the DNR website b4 land purch) show 30 ft thick layer. My disadvantage: the site I chose is a very gradual bowl shape, the majority will be dug (removing 2 - 3 feet) to avg 7 feet deep (9-10 ft center of bowl), sloping to the dam at about 13 - 14 ft. The other concern is that I am only working with about 40-50 acres of drainage, mostly farm land filtering thru the timber surrounding the pond.
