Would a kind content creator consider modelling a South African dam.

As children we used to swim in these dams, which were often found on old towns as well. They were used to irrigated the vegetable gardens.
Sadly to day most have disappeared.
The dam height from memory varied, but I think the height was 6 feet and width varied from 12 feet to perhaps 15 feet.
