Millbrook Reservoir

Millbrook Reservoir, constructed between 1914 and 1918, is a 16,000-megalitre artificial water storage facility located in the Adelaide Hills, South Australia. Built to control water flows in the upper River Torrens, it supplies gravity-fed water to Adelaide's eastern suburbs. The reservoir spans 178 hectares behind a 288-meter clay-cored earth dam on Chain of Ponds Creek. In recent years, SA Water has undertaken significant revegetation projects, restoring 24 hectares into a thriving open grassy woodland habitat with 82 native plant species and over 2.2 million native grasses. This restoration has led to the re-emergence of woodland bird species such as the Buff-rumped Thornbill and Dusky Woodswallow.
