Warragamba Dam Spill Update

Warragamba Dam spill rate has significantly reduced from its peak, with small releases likely to continue over the coming days as inflows to the dam reduce.

At 11 am on Monday, April 8, the spill rate from Warragamba Dam was 19 Gigalitres (GL)/day, and continues to decrease, down from a peak of around 225 GL/day late Saturday morning.

The total volume of the spill from Warragamba Dam has been 260 GL, as at 7 am Monday, April 8, which is equivalent to approximately half the volume of Sydney Harbour.

Other Sydney dams spilling as at 11 am were Tallowa, Nepean and Woronora dams and the Blue Mountain storages, except Upper and Middle Cascades.

• Woronora Dam spilling at a rate of 0.2 GL/day.
• Nepean Dam spilling at 1.5 GL/day and decreasing.
• Tallowa Dam spilling at 22 GL/day and decreasing.

Warragamba Dam Visitor Centre and grounds reopened to the public on Monday, following a public safety review.
