  • A dam is a barrier designed and constructed to contain the flow of water. It is often built in conjunction with a hydroelectric power station to provide electricity.

  • Different types of dams include masonry dams, embankment dams and arch-gravity dams.

  • Beavers create their own dams from sticks and mud as protection from predators and also to help provide easy access to food.
