Pond Boss Forums INTRO Questions & Observations How does a sandy pond seal itself?

I just love the technical stuff. Thinking about it, Brettski, we haven't had a normal month's rainfall in 31 months. Last summer was extreme, this year, only slightly wetter. So, yeah, the underground springs and water table could be a factor. My spring only flows after rains in this drought, but neighbor up the slope says it generally flows year round. And the watershed is undersized. My hydralic ram and solar pumps will take care of that when we get just a little more rain, enough to keep the micro ponds down in the draw with water. I'm holding out for some wet stuff and hope the pond will eventually seal. Ewest, are you saying that sorted sand, silt, and a little clay would work as well as rich clayey soil? And BTW thanks for the expert contribution!
