No matter the size of pond I would recommend looking into your city and state policies before starting on any pond project. I know in my state you need a permit and what not cause something to do with it possibly leaking underground into the water sources or something like that. My Inlaws wanted to put a fishing pond on there 80 acre property and they needed permits to do it. Its a hefty fine if you don't so yah I would look into before hand.
LOL just noticed something, This is a really old post put towards the top so i assumed it was newer
