Avoca Lake

We collaborate with local government to monitor the condition of Avoca Lake. Find out more about the Avoca Lake estuary and its unique features.

Avoca Lake is situated on the Central Coast of New South Wales between the townships of Avoca Beach and North Avoca. It is classed as a back-dune lagoon with an intermittently open entrance to the sea.

Water quality report card

As part of our water quality monitoring program we assess the water quality and ecosystem health of an estuary using a range of relevant indicators. 

The most recent sampling was completed over the 2020–21 summer. The results of the monitoring program, including a detailed water quality report card for Avoca Lake, are available on the Central Coast Council website(link is external).  

Go to estuary report cards to find out what each grade means, read our sampling, data analysis and reporting protocols, and find out how we calculate these grades.
