I spent the morning finessing the shape of the pond and checking the levels of sides. I built the back shelf up a bit with mud and everything else is good enough. I continued being bugged by miner bees, with one pursuing its own hole (which I then sealed with clay).

The bottom of the pond was about 18″, and I managed to scrap another couple of inches of yellow clay out to account for the paddlestone that will go at the bottom.

Afer lunch Mum and I used laminate flooring underlay as the pond underlay. It took longer than the sand, as it was less malleable, but we pinned and cut it to fit fairly tightly. So I’m hopeful that the liner will sit fairly smoothly over it. I’ve put the underlay over the tile I couldn’t shift and the rock that goes there should hide any rise in the liner.
