Kellys Lake is a small back-dune lagoon with an intermittently closed entrance located on the south coast of New South Wales.
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 Kellys Lake 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 good with:
- algae abundance graded fair (C)
- water clarity graded excellent (A)
- overall estuary health graded good (B).
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 Kellys Lake is highly disturbed. Urban development and grazing make up about 85% of land use within the catchment. Forested areas within Eurobodalla National Park form 15% of the catchment.
National and marine parks
- Eurobodalla National Park is the largest conservation area in the Kellys Lake 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 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
Eurobodalla is home to many migratory and shorebirds, which rely on estuaries for food, shelter and breeding grounds.
