Lower Nihotupu Reservoir

The Lower Nihotupu Reservoir (or Lower Nihotupu Dam) is one of five reservoirs in the Waitākere Ranges that supply water to Auckland. Built between 1945 and 1948,[2] the reservoir covers an area of 52.9 hectares and has a capacity of 4.6 million cubic metres.[1] The reservoir is managed by Water Care Services Limited, a council-owned company.
