Dam storage

Dam storage levels includes all of Melbourne's water storage areas that receive water from catchments and the desalination plant. Melbourne’s water storage levels are expressed as a percentage of the combined capacity of all storage reservoirs. This is more accurate than looking at individual reservoirs because of their vast differences in storage capacity.

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