Thanks. We have two small streams/springs feed the pond and it has water flowing in all of the time. With a rain, it would fill in a day. Without it would probably take a few days to fill. I am not sure if a pump would work unless a bulldozer could drive through the muck right after pumping it out.

We were thinking about renting an excavator. Maybe a bulldozer would be a better idea but I have no experience with running one.
