Here is the link to a small pond like that I did with billboard tarps. No issues at all since install. I have a larger one I still pump to but will be adding the liner later. I don't like the idea of bentonite around here because of burrowing crawdads. One burrow and my bentonite layer is worthless. They cant get through the liner though. Good luck.
