Danielle Maltman and other members from the committee recently met with Port Macquarie-Hastings Council staff and other key local community stakeholders.

Mrs Maltman said the reversion of Lake Innes would create an emergency water source for the Port Macquarie-Hastings and the future-proofing of the lakes is urgent.

Revive Lake Cathie is partnering with council and all stakeholders for the implementation of a holistic approach in addressing the crisis.

"According to a new study compiled by council and NSW National Parks and Wildlife Service, the Lake Cathie estuarine system is at 'imminent risk of acidification if the drought continues'," Mrs Maltman said.

"This risk is of grave concern to Revive Lake Cathie members, who seek immediate action from all stakeholders to mitigate the impacts of drought and man-made intervention, as we lead into predictions of future drought conditions."

Mayor Peta Pinson said council takes the condition of the Lake Innes/Lake Cathie estuarine system extremely seriously.

"I as your Mayor, the general manager, senior and specialist staff are all committed to working hand in hand with the many agencies and stakeholders that have a role to play," she said.

Camden Haven Chamber of Commerce executive officer Marisha Woods said the organisation appreciates Revive Lake Cathie's tireless efforts toward future proofing the estuarine system.

"We are pleased to be working together with the key stakeholders toward sustainable solutions," she said.

President of the Lake Cathie Progress Association, Vern Warner said the association is very supportive of the work that Revive Lake Cathie are undertaking.

Mayor Pinson added that many lake systems up and down the coast are suffering at the moment.

"As a group we acknowledge there is no easy or quick solution, however we're extremely encouraged by the informative and positive nature of this stakeholder meeting," she said.

The council started a process in May in a bid to address the crisis facing the ailing waterway of Lake Cathie.

The council will review the Lake Cathie Opening Strategy in consultation with National Parks and Wildlife Service, Office of Environment and Heritage, NSW Fisheries and Department of Industry, and the community including Revive Lake Cathie.

An update report was due to come back to the September council meeting but it has been delayed to the October meeting.
