Rainfall, dam levels & water use

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.

Perth's recent rainfall is welcome but it has made little difference to our dam levels. While it may look like dam levels are increasing slightly at this time of year, this may not be the result of increased streamflow. The water in our dams is no longer just made up of inflows from rain. Groundwater and desalinated water are stored in these dams during periods of low demand so it is available when it is most needed in the hotter months.

Learn more about our drying catchments and how much rain we need to get our streams flowing again.
