Meringo Creek

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

Meringo Creek is a small back-dune lagoon with an intermittently closed entrance located on the south coast of New South Wales. This estuary is surrounded by the Eurobodalla National Park.

Estuary health and 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.

Meringo Creek water quality report card for algae and water clarity showing colour-coded ratings (red, orange, yellow, light green and dark green, which represent very poor, poor, fair, good and excellent, respectively). Algae is rated 'very poor' and water clarity is rated 'fair' giving an overall rating of 'poor' or 'D'. 

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).

We have monitored water quality in Meringo Creek since 2014. This table shows the water quality grades for this estuary over that time.

Meringo Creek historic water quality grades from 2014-15 for algae and water clarity. Colour-coded ratings (red, orange, yellow, light green and dark green represent very poor (E), poor (D), fair (C), good (B) and excellent (A), respectively).

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

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