Station Creek

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

Station Creek estuary is classed as a lagoon and is located within the southern part of Yuraygir National Park on the north coast of New South Wales.

The entrance to this estuary is intermittently open/closed to the sea. Station Creek represents a near-pristine estuary.

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 located between the Queensland border and Taree every 3 years. The most recent sampling in Station Creek was completed over the 2018–19 summer when 2 sites were sampled on a monthly basis.

Station 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 '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 good (B)
  • water clarity graded fair (C)
  • 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 Station Creek since 2010. This table shows the water quality grades for this estuary over that time.

Station Creek historic water quality grades from 2010-11 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

Most of Station Creek catchment is protected within Yuraygir National Park. The remainder is managed by the Forestry Corporation of NSW as part of Barcoongere Forest. A small camping area is located near the lower estuary, which has access roads.

Citizen science projects

  • Caring for our Coastal Emus is a citizen science project coordinated by Clarence Valley Council that involves an online register for collecting data about coastal emus and where they’ve been seen.
