Usually you can, however even with a good clay I would still have it
tested for permeability........you may be surprised. I have what is
called blue merle clay which is a h eavy dark grey blue colored clay
which is about as good as it gets for a pond. I also have clay here
that is a yellow tan color, but it is not suitable for a pond unless
you treat it with bentonite, as its comprised of too much silt and
sand particles thorughout, whereas the blue merle is like a wad of
modeling clay......
