Water Storage Levels
We do our utmost to keep our figures as accurate and up to date as we can, with Water Storage Levels data updated roughly every 1-2 business days. Icon Water’s Water Distribution Engineers do need to verify the data that comes directly from the dams and the Bureau of Meteorology to ensure accurate information before it is published to the website. Please contact us if you are experiencing any issues or have feedback.

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:
Corin 70.8GL
Bendora 11.4GL and
Googong 119.4GL
