Canberra water levels
Four dams across two water catchments service Canberra and Queanbeyan.
The ACT region uses about 50 Gigalitres (GL) of water each year. Every household and business can help to save water by making small changes, such as shorter showers, choosing water efficient appliances and fixing leaks.
Canberra and Queanbeyan have had Permanent Water Conservation Measures in place since 2010. These are common-sense rules that are similar to Level 1 restrictions in other areas. We all have a responsibility to follow the Measures.

ACT and Queanbeyan Dam Storage Levels

GL=Gigalitres. The Murrumbidgee to Googong transfer supplements Googong dam levels.
Historical storage levels
Introducing the enlarged Cotter Dam into our total dam storage capacity means that our total volume has increased from 207GL to 278GL. Previous total storage capacity was around 65% of our new maximum level. For consistency our calculation method is now aligned to that used by the Bureau of Meteorology which counts the volume above the minimum intake level. The enlarged Cotter Dam gives us 76.2GL of usable volume, however in extreme situations it is possible to access the remaining 3.2GL of storage when necessary. Icon Water's other dams have revised total capacities of:
Bendora 11.4GL and
* Previous capacity refers to total combined storage levels before the completion of the new Cotter Dam. The new Dam was built downstream of the old and increased the total water storage capacity by approximately 35%.
