I've recently scooped out an old silted up pond in my garden which filled
up
and overflowed every winter but dried out in the summer. It's a fairly
large triangle of about 20 yards each side. It takes four days to fill
with
a hose and then two days to drain. The clay base (of unknown thickness)
seems watertight, but I reckon it's leeching out where the clay meets the
topsoil sides.

What are my options? It's a bit big for a liner snip

It isnt too big for a liner, just expensive :-)
