Terrigal Beach finally achieves a Good rating

After three years of rating as Poor, Terrigal Beach has finally achieved a Good rating in the 2023/2024 State of the Beaches report.

The recently released report rated all Central Coast beaches as Good or Very Good – an improvement on the 2022/2023 report.

The annual report gives a grading for each designated swim site from Very Good to Poor and is an indicator of suitability for swimming.

It is linked to the statewide Beachwatch Program, which monitors beaches and other swimming sites to ensure that they are safe for recreational swimming.

Water quality can sometimes be affected by microbes and other pollution, especially after periods of heavy rainfall.

Pollution from stormwater and sewage overflows can cause higher levels of bacterial contamination that makes water quality unsuitable for swimming.

Beachwatch data, along with other variables such as rainfall, is used in predictive models to forecast beach water quality on a daily basis.

This enables the community to be able to make an informed decision on whether to swim on any given day.

Central Coast Council monitors 32 recreational sites across the coast – 15 ocean beaches, three ocean baths, four coastal lagoons and 10 estuary sites.

Council Director Environment and Planning Jamie Loader said the 2023/2024 ratings for the Coast’s beaches was pleasing.

“It is really a great result that Terrigal Beach has improved to Good after three years of a Poor rating,” he said.

“Council has done a significant amount of work in the Terrigal Catchment since 2019 including the relining and upgrading of over 32km of sewer pipes and smoke and dye testing to identify illegal connections.

“Lakes Beach, Soldiers Beach and North Entrance have all been graded Very Good – an improvement for Lakes and Soldiers beaches from the previous year’s Good rating.”

Broken Bay beaches were all graded as Good, but the report noted that the water quality at these beaches was often impacted by Hawksbury River floodwater bringing with it contaminants and flood debris.

As in previous years, most estuary and lagoon sites were graded as Poor, the exception being Woy Woy Baths which this year improved to a Good grading.

Loader said that while the estuary and lagoon site gradings were largely Poor, most did show an improvement in the actual microbial assessment with some close to the Good rating.

“These results are indicative of the nature of estuary waterways which flush very slowly and are more susceptible to impacts of stormwater networks,” he said.

“Council is undertaking ongoing studies to determine the causes of these poorer results and remedial work when infrastructure failure is detected.”

Canton Beach Baths, which has been graded poorly for a number of years, also showed an improvement this year.

“Given that it has been another relatively wet year, this improving trend is extremely positive,” Loader said.

“Council is continuing to undertake investigations to understand the contributors to the poor results in this area.”

Loader said a contributing issue with many sites is the ‘dog poo’ factor, which has been detected through microbial source tracking.

“Recent DNA studies on microbial sources identified human, canine and avian sources to microbial contamination highlighting that both Council and the community have a role in improving our estuarine water quality,” he said.

Actions for the community include picking up after dogs, reducing sewer network blockages by only putting the three Ps – poo, (toilet) paper and pee – down the toilet and keeping litter and other pollutants out of stormwater drains.

Mayor Lawrie McKinna said the report was a timely reminder that all swimming sites could be affected by stormwater pollution.

“The numerous beautiful beaches of the Central Coast are at the heart of what makes this region special, and it is vital that we take care of these precious waterways,” he said.

“While our State of the Beaches report card for 2023/2024 saw significant improvement, we will continue to roll out a number of measures designed to further improve water quality across the Coast.”

Avoid swimming at ocean beaches for 24 hours and at estuary sites for 72 hours following heavy rain.
