I live in central Florida and want to build a rather small pond approx 15 yards wide and 60 yards long. Depth to be about 6 ft. I don't care about fish, etc as this will be used for training Labrador Retrievers. The current water table is at 4-5 ft. There is no spring or stream to supply water. It will all be from the water table and rain run off.Is there anyone out there that has any experience in this type of pond?
