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 the Queensland border and Taree every 3 years. The most recent sampling in Corindi River was completed over the 2021–22 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 report card shows the condition of the estuary was good with:
- algae abundance graded good (B)
- water clarity graded good (B)
- overall estuary health graded good (B).
Coffs Harbour City Council, in collaboration with the University of New England’s EcoHealth Program, have carried out detailed ecosystem health monitoring in Corindi River. The results of the monitoring program, including a detailed water quality report card, are available on the Coffs Harbour City Council website.

We have monitored water quality in the Corindi River since 2009. 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.
