Summer storms soften storage slide
Substantial rain at the major catchments has slowed the rate of decline in water storages.
Storages declined by 0.2% - 3.8 billion litres – over the past week, which was well below the weekly average for summer (0.5%).
The good result came as the catchments received between 23.4 and 58.4mm of rain, with an average of 43.9mm. This was four times the long-term average for the period (10.8 mm).
Despite the wet week, the 4.6 billion litres of streamflow was 11.3% below the 30-year average for the period (5.1 billion litres).
The disparity between rainfall and streamflow is attributed to hot weather and minimal rainfall in preceding weeks. These conditions dry catchments, hampering their ability to generate streamflow.
Water storages are now 76.4% (1,384.0 billion litres) full, compared with 79.8% (1,446.7 billion litres) at the same time last year – a difference of 62.7 billion litres.
Melburnians used an average of 142 litres of water per person a day. This is 67 litres less than the previous week.
