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.
We capture daily information about each of our reservoirs in the Mount Lofty Ranges catchment area. Click on individual reservoirs on the map below to learn more about their current volume, history and visiting times.

At certain times, some of our reservoirs are able to record more than 100%. You can find out how a reservoir can be more than 100%.
Keeping our reservoirs clean is an important part of protecting our water supply. Some of our reservoirs are open to the public to visit but access to the water is restricted. You can see when you can access the sites by clicking on the individual reservoirs on the interactive map or links above.
All reservoirs are closed on Total Fire Ban Days. They are also closed on Christmas Day and Good Friday.
