Cuttagee Lake

Our water quality monitoring program has shown Cuttagee Lake to have good water quality. Find out more about the estuary and its unique features.

Cuttagee Lake is a small lagoon located on the far south of New South Wales, south of Bermagui. It is classed as a lagoon, with an intermittently closed entrance.

Cuttagee Creek and Buggy Creek are the main tributaries for this estuary.

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 Cuttagee Lake was completed over the 2017–18 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.

Overall grade

The report card shows the condition of the estuary was good with:

  • algae abundance graded good (B)
  • 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 Cuttagee Lake has relatively low disturbance, with over 90% forest in Biamanga National Park. Urban, rural residence and grazing constitute almost 5% of the land use.

Get involved

National and marine parks

  • Biamanga National Park is the largest conservation area for Cuttagee Lake.
  • This estuary does not flow into a marine park.

Citizen science projects

  • The Far South Coast Conservation Management Network supports the local community to better manage native biodiversity. The network organises citizen science projects, provides information for private landowners, manages a local plant database, and coordinates events.

Local government management

Local councils manage estuaries within their area unless the estuary is attached to a marine park.

Bega Valley Shire Council manages this estuary.

Threatened species

Estuaries provide important breeding, nursery and feeding grounds for many fish and birds.
