Well, it nearly killed me, but I now have a raised pond.
(apart from the disaster with the liner when the rocks holding the liner
fell in and holed it doh !)

It's rectangular, made from sleepers which are lined them 'cos they were
full of creosote.
However, we're about to top it off with some wood, but I'm at a loss at how
to treat it.
Can't use creosote as we want fish, don't know about cuprinol ?

The top wood would never touch the water, but I'm worried about run off from
rain, pond overflow etc
