Pond leaks are extremely vexing. The only way that I know to find them is to pump it dry and take a good look. The crawdads could be a problem but are more likely to be a symptom of a problem. You might not have enough clay walked in on the bottom. If you are seeing water funneling into their holes, they need to be eliminated. If they are naturally occuring, that could be easier said than done.

Contact Otto (Mike Otto) and set up an appointment for a phone call. For a consultant in your area, contact the Pond Boss office. Lusk ought to know somebody in your area.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
