Most pond liners are made from polyethylene, which is pretty inert in the 
realm of plastics- no BPA.  Bentonite is also great, though both have their 
embodied energy.  

Another method is to use pigs.  Once you dig out your pond, put the pigs in, 
spreading their feed up the walls that have been moistened.  They will root 
out the feed mashing the mud.  Pigs supposedly have an enzyme in their saliva 
that makes clay coagulate.  Joel Salatin calls it the "squealer sealer". 

Whatever you do, dig your catchment deep and try to shade it, as evaporation 
is a concern.  Look into Keyline design for ideas of how to harvest rainwater 
from runoff.  A good book is "Water for Every Farm" by P.A. Yeomans.
