Dams are built across rivers, streams and estuaries to retain water.
Most dams have one purpose and that is to retain water (to prevent floods). Other dams can be used for fishing, generating hydro electric power, and they can also be used for the improvement of navigation.
Water Care operates fourteen supply reservoirs. Five of them are located in Waitakere Rangers, two are near Helensville and four are in the Hunua Ranges.
Dam supply about 80% of Auckland's water. Dams are built really high. After World War 2, dams were made out of earth and rock.
The Waitakere Ranges have five dams. Three of them are made out of concrete and two are made out of earth.
