Baragoot Lake

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

Baragoot Lake is located on the far south coast of New South Wales. It is classed as a back-dune lagoon with an intermittently closed entrance. When the entrance is open, Baragoot Lake flows into Baragoot Beach. Mangans Creek is the major tributary for this waterway.

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

Baragoot 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 fair with:

  • algae abundance graded fair (C)
  • 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 Baragoot Lake since 2008. This table shows the water quality grades for this estuary over that time.

Baragoot Lake historic water quality grades from 2008 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.

Land use

The catchment of Baragoot Lake has relatively low disturbance with almost 70% forest, most of which falls within Bermaguee Nature Reserve and Biamanga National Park. Urban and grazing areas each occupy about 10% of the catchment.

National and marine parks

Citizen science projects

  • The Far South Coast Conservation Management Network supports the local community to better manage native biodiversity. The network organises citizen science projects, provides information for private landowners, manages a local plant database, and coordinates events.
