Dry summer conditions bring no relief to storages

Similar to this time last year, the four major catchments received 0.0 mm of rain compared to the long-term average for the period of 21.2 mm.

The 1.5 billion litres of stream flow was 64.9% below the 30-year average for the period (4.2 billion litres).

Water storages are now 65.9% (1,193.5 billion litres) full, compared with 74.3% (1,347.2 billion litres) at the same time last year - a difference of 153.7 billion litres.
