Lake Cathie closes to the ocean; recreational activities still encouraged

LAKE CATHIE has closed to the ocean, however Port Macquarie-Hastings Council says conditions remain “ripe for recreation”.

Excessive sand movement and dry conditions have caused the sand berm to close the entrance to the ocean, after more than 15 months of favourable weather conditions allowing it to remain open, according to Council.

This is a naturally occurring process and a regular phenomenon for Intermittently Closed and Open Lakes and Lagoons (ICOLLs).

An opening will typically occur when water levels rise due to rainfall, while closures happen as sand accumulates – creating a berm which acts as a natural seal between the lake and ocean.

Mayor Adam Roberts said the closure is a normal part of the lake’s natural cycle and should not deter people from enjoying the lake’s recreational offerings.

“Lake Cathie has been open to the ocean for an extended period, and it’s been wonderful to see so many people out enjoying the pristine conditions we have been blessed with for more than 15 months,” Mayor Roberts said.

“The recent closure is part of the normal opening and closing process of ICOLLs, and conditions for swimming, fishing and other recreational activities are still suitable.”

As part of the Lake Cathie Standard Operating Procedure, Council is only authorised to conduct an artificial opening during emergency scenarios when water levels threaten critical infrastructure and surrounding properties.

“I understand and appreciate that many locals and visitors do prefer the environment more when it’s open, however it’s important to remind our community that Council only has a license to conduct an artificial opening during emergencies, and not to improve the lake’s recreational amenity,” Mayor Roberts said.

“Council last conducted a scrape of the lake’s berm in May 2024 when water levels reached the required emergency trigger point after a sustained period of rainfall.

“This opening was conducted to proactively protect nearby infrastructure and properties at increased risk of flooding.”

Council staff will continue to monitor water levels and quality.

“Separate works will also progress with foreshore maintenance and protection to the embankment at Lake Cathie, caused by recent erosion, during November,” Mayor Roberts said.
