Information on this page may not be current and can change. Our Dam Rangers collect dam rainfall readings and may not be able to do this daily. Please note the rainfall instruments located at Victoria Dam and Mundaring Weir are being serviced and are not currently recording rainfall. We are working to address this and resume measurement as soon as possible.
