We only had 2-3 inches of top soil when we dug the pond and the rest was clay and the deeper they dug the more moist it got.
I'm hoping saturation because there is a water stain about 3 foot up the damn sides and all around the pond above the water level. The ground is really wet all around the pond.
We started filling the pond on March 7th. and it only took two weeks to fill to capacity.
