Central Coast Council is currently monitoring record-breaking dam levels across the region, advising impacted communities and optimising treatment processes.
Council is looking to maintain water security as water storage increases to full capacity at Upper Mooney Dam and Mangrove Creek Dam, due to high levels of continued rain.
Although storm flow has increased the turbidity and colour of water supply sources, Council has said its two treatment plants are performing well.
Council is selecting best quality water sources to use and is currently drawing water from Mardi Dam and the Upper Mooney Dam.
Central Coast Council Director Water and Sewer, Jamie Loader, said this is the first time Mangrove Creek Dam has reached full capacity since construction was completed in 1982.
“This storage increase places the Central Coast water supply in a secure position for years to come,” Cr Loader said.
“Although rising water levels are unpredictable during a natural disaster, Council crews are on ground monitoring the situation and providing daily advice to impacted communities as required.
“While the overflow from the Mangrove Creek Dam will contribute to the level of the already flooded rivers, it is a relatively low rate and small in comparison to existing catchment flows.
“For comparison the current flow over the spillway is less than 2GL per day, with the Warragamba Dam spilling at 515GL per day at its peak.
“The dam level remains significantly below any levels that require activation of the Dam Emergency Plan.”
The Dubbo Gully Area downstream of Mangrove Creek Dam remains closed due to flooding.
Whilst the Mangrove Creek Dam Picnic Area remains open, the Mangrove Creek Dam spillway is not visible from this area.
