Jerusalem Creek

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

Jerusalem Creek is a lagoon with an intermittently closed/open entrance. It is located within Bundjalung National Park on the north coast of New South Wales.

The estuary is an important shallow lagoon wetland system with largely undisturbed grasslands and riparian vegetation communities.

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 Jerusalem Creek was completed over the 2018–19 summer when 2 sites were sampled on a monthly basis.

Jerusalem 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 'excellent' and water clarity is rated 'excellent' giving an overall rating of 'excellent' or 'A'.

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 excellent with:

  • algae abundance graded excellent (A)
  • water clarity graded excellent (A)
  • overall estuary health graded excellent (A).

We have monitored water quality in Jerusalem Creek since 2009. This table shows the water quality grades for this estuary over that time.

Jerusalem Creek historic water quality grades from 2009-10 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 Jerusalem Creek falls within the protection of Bundjalung National Park and is barely disturbed today. Commercial sand mining occurred between 1932 and 1982 and a large pile of tailings remain west of the creek. There is also a small camping area and some unsealed roads near Jerusalem Creek.

National and marine parks

Local government management

Local councils manage estuaries within their area unless the estuary is attached to a marine park. Jerusalem Creek is managed by Richmond Valley Council.
