This data reflects the reservoir levels as of 8am ACST and is uploaded to this page at approximately 12pm ACST each weekday.

Our reservoirs are our primary water storage areas. They supply homes and businesses across South Australia. The reservoirs don't just fill with rain, we can also use them as storage for River Murray water to help meet customer demand.

At full capacity, our reservoirs can hold almost 200,000 megalitres (ML) of water. This equates to just under a year's supply for metropolitan Adelaide.

How full are they?
