I've seen a product that you can buy to do this. It comes as smallish
plastic grids which are fixed just below the water level. Plants can still
grow thru it, it's quite difficult to see, and can easily take the weight
of
a full grown adult. Not sure what it was called tho. It was on one of
those
garden makeover programs in the last month or so.

I saw it too and it looks excellent if it can be installed into a new pond.

However, I was concerned that the weight of a foot standing on it would not
be sufficiently dissipated to stop piercing a liner.

I think (unfortunately) the only solution to the "young children plus ponds"
dilemma is a metal grill over the top or VERY high walls around the sides.

:-)

Which gets me thinking more seriously, what are the chances of fencing off
the area with the pond/s in and fitting a self-closing childproof lock to
the one and only gate entrance?
