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

Kellys Lake is a small back-dune lagoon with an intermittently closed entrance located on the south coast of New South Wales.

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 Kellys Lake was completed over the 2014–15 summer when 2 sites were sampled on a monthly basis.

Kellys Lake 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 'good' and water clarity is rated 'fair' giving an overall rating of 'good' or 'B'.

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 fair (C)
  • water clarity graded excellent (A)
  • overall estuary health graded good (B).
