Bullengella Lake is a small estuary located on the south coast of New South Wales near the township of Narooma. It is classed as a lake 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 Bullengella Lake was completed over the 2008–09 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 poor with:
- algae abundance graded very poor (E)
- water clarity graded good (B)
- overall estuary health graded poor (D).
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 tiny catchment of Bullengella Lake is moderately disturbed. About half of the catchment is used for grazing and about 20% is forested.
National and marine parks
- There are no conservation areas in this catchment.
- This estuary flows into the 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 NSW 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 manages this estuary, which is located in Batemans Marine Park.
Threatened species
Estuaries are important to our native animals as they provide food, shelter and breeding grounds.
