Mark - Tim here - you have seen my pond so you can get an idea of value - previous owner built it in 1992 - 8 acres, 40 feet deep, huge dam built with clay taken from about 200 yards away, damn leaks not a drop, nice spillway, boat ramp and runoff rocked in, etc. His cost was near $100,000 ten years ago - worth that much to build??? probably not. Value to me?? priceless! Hard to put a price on value of a recreational lake - anyway, FYI on cost of building a larger pond.
