Here you can check rainfall and dam levels and find out how declining rainfall is affecting the amount of water that flows into our dams.
You can also learn where we source your water from and how our water usage is tracking.
New dam and rainfall webpages coming soon
We are currently improving the rainfall, dam levels and water use webpages.
Take a sneak peak at what we are proposing and provide us with your feedback.
