Cararma Creek

Our water quality monitoring program has shown Cararma Creek to have excellent water quality. Find out more about the estuary and its unique features.

Cararma Creek is located on the south coast of New South Wales and flows into the north east part of Jervis Bay. It is classed as a lake.

This estuary represents a relatively natural system because the catchment and waterway are protected by conservation areas.

Estuary health and features

Water quality

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 Cararma Creek was completed over the 2011–12 summer when 2 sites were sampled on a monthly basis.

Cararma Creek water quality report card for algae and water clarity showing colour-coded ratings (red, orange, yellow, light green and dark green, which represent very poor, poor, fair, good and excellent, respectively). Algae is rated 'good' and water clarity is rated 'good' giving an overall rating of 'good' or 'B'.

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.

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

  • algae abundance graded good (B)
  • water clarity graded excellent (A)
  • overall estuary health graded excellent (A).

Citizen science projects

  • The Budawang Coast Nature Map is an online data platform the community can use to record and identify biodiversity. Data collected is used to map the distribution of native plant and animal species from Moruya up almost to Kiama.

Local government management

Local councils manage estuaries within their area unless the estuary is attached to a marine park. Carama Creek estuary is managed by Jervis Bay Marine Park.
