In Auckland dams block the flow of water in rivers and streams. Water must pass over or through a barrier on the upstream side. Dams are built over a stream or a river or an estuary to retain the water. Many dams are for a reason. Dams are also used to prevent flooding. Water Care operates 14 supply reservoirs, five in the Waitakere Ranges, two in Helensville and 2 of the reservoirs located in Hunua Rangers
