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.
We need steady, regular rain in order to soak our catchments and get the streams flowing into our dams. Slowly declining rainfall means Perth's dams receive much less streamflow than in years past.
*In order to provide an accurate historical comparison streamflow from Stirling and Samson Brook Dams are not included in this data as these dams only came online in 2001. Inflow is therefore modelled on Perth dams pre-2001.
