Lower Nihotupu Reservoir
The Lower Nihotupu Reservoir is one of five reservoirs in the Waitākere Ranges that supply water to Auckland. Built between 1945 and 1948, the reservoir covers an area of 52.9 hectares and has a capacity of 4.6 million cubic metres. The reservoir is managed by Water Care Services Limited, a council-owned company.
The dam is credited as one of the first applied examples of the soil mechanics science in New Zealand, and was soon followed by the creating of engineering geology as a major subject at the University of Auckland Faculty of Engineering.
