The current streamflow amount is 0 GL
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 streamflow figure shown above is for all the dams that supply the Integrated Water Supply Scheme.
