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.
The Winter Sprinkler Switch-Off is now in place for scheme and bore water users in Perth, Mandurah and parts of the South West and Great Southern.
We have resolved the issue with our dam level and streamflow reporting and the data will now be regularly updated. See our Metro Weekly Water Update for more information.
We need steady, regular rain in order to soak our catchments and get water flowing into our dams. Slowly declining rainfall means Perth's dams receive much less streamflow than in past years. Streamflow is the amount of water entering our dams from our catchments and is measured by changing water storage levels.
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 how the drying climate continues to impact rainfall, the streams that flow into our dams and water use.
