I am looking for something to help with a dug pond. I am in South Texas and the pond was dug and lined with clay from our site whe nwe built a house right before Hurricane Harvey. The pond was coming up slowly and Harvey filled it completely in about 8 hours. This washed the clay fairly deeply. We have decent drainage to the pond and also have a 1 inch line for pumping when needed. Seems like you can get it to about 6 feet then it starts leaking. Maximum depth is probably around 10 feet.
