Storages gain from previous rain
Melbourne’s water storages continued to rise this week, increasing by 0.2% of capacity.
The 3-billion litre gain was due largely to the legacy of high rainfall in the previous week.
The four major catchments received between 3.0 and 23.2 mm of rain, the average being 10.3 mm. This was about half of the long-term average for the period (20.2 mm).
The key to the weekly rise was the high rate of streamflow - essentially last week’s rainfall continuing to make its way through the catchments.
The 9.6 billion litres of stream flow was almost double the 30-year average for the period (5.0 billion litres).
The weekly result also accounts for the release of 2.3 billion litres of environmental flows into the Yarra River.
Storages are now 69.6% (1,261.3 billion litres) full, compared with 71.4% (1,294.3 billion litres) at the same time last year – a difference of 33 billion litres.
Residential water use increased slightly, partly due to lower rainfall. Melburnians used an average of 147 litres of water per person per day. This is 5 litres a day more than the previous week.
