Dam storage level

Melbourne's total dam storage level is a percentage of the combined capacity of all storage reservoirs. We include all of Melbourne's water storage areas that receive water from catchments and the desalination plant. 

Volumes are measured over a 24 hour period to 8am each day and are validated at the end of each week.
