What does this mean?
Our metro dams are currently holding
than this time last year.
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.
