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.
Winter rains sometimes linger into spring – so keep your sprinklers off while your garden receives a free drink from the sky! Now is also the time to consider more climate tolerant plants for your garden – they look great and need less water. Find waterwise plants to suit the conditions where you live in WA, by using our Waterwise plant search.
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 impact of climate change continues to affect rainfall, the streams that flow into our dams and water use.
