No increase in storages after below average rainfall


Melbourne's water storages remained steady at 72.6% of capacity this week.

The four major catchments received between 0.8 to 3.4 mm of rain, the average being 1.2 mm. This was 93.5% below the long-term average for the period of 18.5 mm.

The 8.3 billion litres of stream flow was 1.3% below the 30-year average for the period (8.4 billion litres).
 
Water storages are now 72.6% (1,315.5 billion litres) full, compared with 71.4% (1,294.6 billion litres) at the same time last year.

This represents a difference of 20.9 billion litres.

Melburnians used an average of 150 litres of water per person per day.

This is 18 litres less than the previous week.

Permanent water use rules are currently in place and Target 155 has been launched to encourage Melburnians to reduce water consumption.

Information on Target 155 is available on the Department of Environment, Land, Water and Planning’s website or by contacting your local water retailer.
