My wife and I own 75 acres of forest land in western North Carolina, and some years ago we dammed up a creek and created a body of water which has a surface area of about 1 1/2 acres, 18 feet deep at the deepest part. It is fed by the creek and by several year-round springs, and it stays full all year round. We have tried to figure out whether we should call this a pond or a lake. It is the second largest body of water in the county. It is deep enough that vegetation does not grow on the bottom in the deep parts. It is man-made. We intend for it to be permanent. We have found various opinions regarding the differences between a pond and a lake. I would like to know whether people reading this forum can help us to decide whether we have a pond or a lake, and what their reasons are. Many thanks for your help.
