Pond Boss Forums POND CONSTRUCTION Building a dam New pond seepage. Is this normal?

As long as the equipment will be there and the ground tore up anyway, I'd re-do the core too. I prefer to go the belt and suspenders route rather than have to re-do it again later.

If it was my pond, I'd feel better if there was an 18" thick to 24" thick clay liner all over the pond. from bottom to above the high water line. Plus making sure the dam core is good and tied into good soil at the ends of the dam.

If only the bottom of the pond is lined, what is stopping the water from escaping above where the bottom clay liner stops?
