A good place to start is by getting some test holes dug to see if clay is available for a pond rebuild. Bentonite can work but the big problem with it is when the pond looses water to evaporation and is not kept full the bentonite seals crack and will then tend to leak. Thinner clay liners can also crack during droughts. The pond will probably have to be rebuilt and dug deeper if you want it to reliably hold water.
