About Elizabeth River estuary

The Elizabeth River estuary contains seagrass beds that provide feeding grounds for dugong and turtles.

Large parts of the estuary are still lined with mangroves but industrial development along the foreshore has reduced mangrove cover in recent years.

The estuary receives urban stormwater runoff from the city of Palmerston during the wet season and dispersed discharge from the Palmerston wastewater treatment plant that enters the harbour in Myrmidon Creek.
