Water quality in the Middle Harbour was very good.
About Middle Harbour
The Middle Harbour zone receives urban and industrial stormwater runoff from the city of Darwin and development at Wickham Point.
The harbour’s main shipping channel transverses this zone and it receives dispersed discharge from the Ludmilla wastewater treatment plant at the East Point outfall.
Seagrass beds occur in Fannie Bay, where dugongs can often be seen. A shallow coral reef that is exposed at extreme low tides extends around East Point.
