Thanks for the welcome! My pond is literally on top of a mountain near a cliff. Last year the water was leaking in a spot my dad fixed years ago. I cleaned out the two holes of any lose debris, poured some ready mix in it, then mixed some bentonite and clay and put on top of it. I'm confident those two spots are fixed since the water stays up about a foot more than it use to, but it leaks down a foot in four or five days as the level rises. I think it's leaking near the patch. There are "bench rocks" in that area. Gonna try some more clay/bentonite where I think it's leaking. If that doesn't work, gonna have to get serious! Anyhow, I enjoy reading the forum and Pond Boss magazine.
