Hydatid disease is a serious human health concern, caused by cysts of the tapeworm parasite Echinococcus granulosus.

The health and nutrition of the pregnant ewe largely determines how successful lambing is in any given year.

By following this guide, you can estimate the amount of water stored in a dam, and how evaporation and water for livestock, spraying and other uses will affect water reserves. This guide suits farm dams up to about 10 000 cubic metres. This page does not cover large gully-wall dams.
