Many people would not think of dams as being heritage assets, but there a number of historic but still operational dams in the Auckland region. Ref: JTD-07B-03192, Huia Dam, 1941, West Auckland Research Centre The Waitakere Ranges Water Supply System draws water from the ranges in West Auckland including the Huia, Nihotupu and Waitakere streams. During the 20th century, five large dams were constructed. These created the a series of reservoirs and associated tramways, piping, tunnels and filter stations. The main dams which are still in use include: the Waitakere Dam (1910), Upper Nihotupu Dam (1923), Upper Huia Dam (1929), Lower Nihotupu Dam (1948) and the Lower Huia Dam (1971).
