Millbrook Reservoir

Millbrook Reservoir

The construction of the Millbrook Reservoir spanned the years of the First World War.

It was built to control flows in the upper reaches of the River Torrens and gave Adelaide 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

Open to the public: No
