Lake Brunderee is located on the south coast of New South Wales. It is classed as a small lagoon with an intermittently closed entrance.
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. We sample a subset of the estuaries between Wollongong and the Victorian border every 3 years. The most recent sampling in Lake Brunderee was completed over the 2014–15 summer when 2 sites were sampled on a monthly basis.
This report card represents 2 water quality indicators that we routinely measure: the amount of algae present and water clarity. Low levels of these 2 indicators equate with good water quality.
Algae
Water clarity
Overall grade
The report card shows the condition of the estuary was very good with:
- algae abundance graded good (B)
- water clarity graded excellent (A)
- overall estuary health graded excellent (A).
Grades for algae, water clarity and overall are represented as:
- A – excellent
- B – good
- C – fair
- D – poor
- E – very poor.
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.

Land use
The catchment of Lake Brunderee is relatively undisturbed with over 90% remaining forested, most of which is protected within Eurobodalla National Park. Urban land use at Potato Point accounts for about 1% of the catchment.
National and marine parks
- Eurobodalla National Park is the largest conservation area in the Lake Brunderee catchment.
- This estuary flows into Batemans Marine Park.
Citizen science projects
- iNaturalist’s Plants of Eurobodalla is a citizen science project that monitors plants found in the Eurobodalla region.
Community involvement
- Eurobodalla Landcare is a volunteer network of 24 Landcare groups on the New South Wales south coast.
- The Coastwatchers Association is a community environmental and conservation group based on the south coast.

Local government management
Local councils manage estuaries within their area unless the estuary is attached to a marine park.
Eurobodalla Shire Council manage this estuary, which is located in Batemans Marine Park.
Threatened species
Estuaries provide important breeding, nursery and feeding grounds for many animals, such as fish and birds.
