The eastern part of NSW has been experiencing record rains for days and now with rivers overflowing, many areas are set to flood.
An evacuation order was issued for Picton, about 40km away from the dam, just over an hour after it started overflowing. Other areas are set to be evacuated soon.
A spokesperson from WaterNSW said other dams near Sydney were also set to overflow, including Nepean, Cataract, Cordeaux and Avon dams.
“WaterNSW has established a dedicated 24-hour incident management team that is working closely with the Bureau and the NSW State Emergency Service to monitor weather and inflows to dams,” they said.
“WaterNSW will continue to work closely with Sydney Water and NSW Health throughout the rain event, to watch for potential water quality impacts on untreated supply.”
“It’s a very dynamic and evolving flood situation and we could see some very deep and rapid responding rivers with very high levels,” the State Emergency Service said.
