The house I just bought has a pond that was dug a couple of years ago. The soil is mainly clay and some shale. It is dug around 10-12 feet deep. It won't hold water past 12-15 inches. The pond is probably around 1/3 of an acre big. Does anyone have any ideas on how I can get it to hold water? I have called the county extension office and searched the internet with no luck. I really want to fix this so I could stock it and be able to enjoy it instead of looking off my back deck to a deep hole with a puddle in it.
