Water Management

With a breathtaking mix of weathered landscapes, vast plains, rivers, wetlands and coastal and marine environments, the Darwin Harbour Catchment holds significant social, economic, environmental and cultural importance within the Top End Community. Covering 3227sq km, the Catchment stretches from the cities of Darwin and Palmerston extending as far south as Darwin River Dam to the outskirts of Humpty Doo, the Cox Peninsula and the settlements of Belyeun and Wagait Beach.

The Mary River is located 90kms east of Darwin in the Northern Territory with a catchment that covers an area of 8100 km2 with predominately freshwater wetlands extending over approximately 1,300 km2. It is a highly productive area which supports multiple land uses as well as providing habitat for a large range of wildlife, including saltwater crocodile Crocodylus porosus, magpie goose Anseranas semipalmata and barramundi Lates calcarifer.

A wide range of management reforms for better use of water resources has already been completed by the NT and independently assessed by the National Competition Council and the National Water Commission. The National Water Initiative (NWI) has been endorsed by the Council of Australian Governments to drive more reforms for better water management and use to the year 2011.

The Weed Management Branch works to continually preserve and improve our natural resources, industries, life styles and environment from the introduction and spread of weeds. Weed Management Branch activities include exclusion, eradication where possible, survey & control, data management, education, and in cooperation with other agencies and states integrated management including biological control.

Protecting our precious water resources is essential to our natural Territory lifestyle. Water quality management goals, appropriate indicators of water quality and water quality objectives are developed to protect the required values and beneficial uses. Water quality monitoring can be undertaken using chemical or biological testing indicators. Information on relevant acts and regulations can be found through the links.
