Don't know about other ponds, but mine drops an inch a week. It's doen this since it was full enough that I could start measuring it. If it's really hot out, that number triples.
Since it's been consistant, I either have a leak that has been ongoing since day one, or it's normal evaporation, which I believe to be true.
If it's leaking from day one, why would it stop leaking on it's own?
