Nerrindillah Creek

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

Nerrindillah Creek, also known as Nerrindillah Lagoon, is classed as an estuarine creek with an intermittently closed entrance. It is 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 Nerrindillah Creek 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.

C

Algae

B

Water clarity

Overall grade

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

  • algae abundance graded fair (C)
  • water clarity graded good (B)
  • 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.

Local government management

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