Millbrook Reservoir

Millbrook Reservoir

The construction of the Millbrook Reservoir spanned the years of the First World War, 1914 to 1918. It was built to control flows in the upper reaches of the River Torrens and gave us a reservoir in the Mount Lofty Ranges that is high enough to supply water using gravity feed to Adelaide's eastern suburbs.

Water can be released from Millbrook Reservoir back into the Torrens to supplement water into the Kangaroo Creek Reservoir.

Capacity: 15.7 gigalitres (one gigalitre is one billion litres), which would fill nearly 8,000 Olympic swimming pools

Public access: No
