Our water quality monitoring program has shown Meringo Creek to have good water quality. Find out more about the estuary and its unique 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 Meringo Creek 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 fair with:
- algae abundance graded poor (D)
- water clarity graded excellent (A)
- overall estuary health graded good (B).
Find out more about our estuary report cards and what each grade means. Read our sampling, data analysis and reporting protocols and find out how we calculate these grades.
We have monitored water quality in Meringo Creek since 2014. 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.
