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

Racecourse Creek is situated on the mid-north coast of New South Wales in the township of Old Bar. It is a small urban creek with an entrance intermittently open to the sea.

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 located between Taree and Wollongong every 3 years. The most recent sampling in Racecourse Creek was completed over the 2019–20 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.

Historical water quality grades

We have monitored water quality in Racecourse Creek (Old Bar) since 2013. This table shows the water quality grades for this estuary over that time.

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

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