Currambene Creek

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

Currambene Creek is classed as a barrier river estuary with an intermittently closed entrance. It is located on the south coast of New South Wales.

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 Currambene Creek was completed over the 2017–18 summer when 2 sites were sampled on a monthly basis.

Currambene 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 'excellent' 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 good with:

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

We have monitored water quality in Currambene Creek since 2011. This table shows the water quality grades for this estuary over that time.

Currambene Creek historic water quality grades from 2011-12 for algae and water clarity. Colour-coded ratings (red, orange, yellow, light green and dark green represent very poor (E), poor (D), fair (C), good (B) and excellent (A), respectively).

Grades for algae, water clarity and overall are represented as:

  • A – excellent
  • B – good
  • C – fair
  • D – poor
  • E – very poor.

Land use

Currambene Creek receives runoff from a moderately disturbed catchment. Over half the catchment is forested and includes part of Parma Creek Nature Reserve. Grazing land at Currambene Creek and Parma account for 20% of land use. Urban areas make up about 10% of the catchment and include the townships of Woollamia and Falls Creek.

National and marine parks

  • Parma Creek Nature Reserve is the largest conservation area in the Currambene Creek catchment area.
  • The Currambene Creek estuary flows into the Jervis Bay Marine Park. The entrance of the estuary is included in the habitat protection zone for the bay.

Local government management

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

Currambene Creek estuary is managed by Shoalhaven City Council and the Jervis Bay Marine Park.
