Hi all,

Having said that digging the pond would have been a lot easier if there hadn't been rock really near the surface. I would have gone deeper, but it was only a shallow "rubble" layer <"before I hit the bedrock">.

It definitely works, the other advantage is that the liner isn't exposed as the water level drops.making the wall with loads of caves and nooks and crannies below the water surface.
I was lucky there, I just put the stone I'd dug out making the pond, back into the pond <"to create the rock terraces">.but yet could not source the material for it. All I can find in my region offering garden design materials are way to expensive for that.
