At 287 giga litres Cardinia Reservoir is Melbourne Water’s
second largest reservoir. Constructed in the early 1970’s
it has no direct catchment, instead water is fed via Silvan
Reservoir and more recently the Victorian Desalination
Plant.
With recent improvements in dam safety and design
standards Cardinia Dam has slipped below best practice
guidelines in dam safety.
The upgrade to Cardinia dam will bring the fifty-year-old
structure back into compliance with the guidelines issued
by the Australian National Committee on Large Dams.

Melbourne Water has a duty of care to comply under the
Water Act 1989 for all dams within its portfolio.
The upgrade works are due to start in 2024/25 and
expected completion is mid 2025
