About the Outer Harbour
The Outer Harbour is a well-mixed system open to coastal exchange.
It receives urban stormwater from Darwin’s northern suburbs and effluent from the Ludmilla Wastewater Treatment Plant is discharged to this part of the Harbour at the East Point outfall.
Seagrass beds occur off Casuarina Coastal Reserve where dugongs can be spotted regularly.
The distribution of the data for all parameters is shown here as box and whisker plots.
For report card grades the median of the data (solid line in the box) is compared to the Water Quality Objective (dotted line) for each parameter.
