Towradgi Creek

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

Towradgi Creek is a small saline coastal lagoon, it is classed as a creek with an entrance that is intermittently open and closed to the ocean, located in the Illawarra region 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 Towradgi Creek was completed over the 2022–23 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. The numerical scores for these 2 indicators are averaged to give the overall grade. 

C

Algae

D

Water clarity

D

Overall grade

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

  • algae abundance graded fair (C)
  • water clarity graded poor (D)
  • overall estuary health graded poor (D).

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. Where an estuary is attached to a marine park, marine park management teams are responsible for ensuring compliance with marine park zoning.

Threatened species

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