A decision support system for water quality improvement in Myall, Smith and Wallis Lakes

In 2002, the Australian Government initiated a national programme (the Coastal Catchment Initiative [CCI]) which aimed to improve the management of coastal catchments. The Great Lakes region of New South Wales, Australia, was selected CCI projects.

The region includes the Myall Lakes, Smiths Lake and Wallis Lake catchments which support a large number of native plant and animal species, including several endangered and vulnerable species. The lakes support local tourism, oyster farming, prawning and fishing industries, and agricultural activities.

Maintaining good water quality in these lakes is vital to their long term ecological health and the sustainability of the economies they support. Threats to the health of the lake ecosystems are mainly nutrient and sediment inputs from urban, industrial and agricultural land uses in the catchments.

As part of the Great Lakes CCI, the ANU developed the CAPER decision support system (DSS) to explore how the health of the lakes might improve with better management of their catchments.

This project was majority funded by the Australian Government through the ‘Natural Heritage Trust’.


The Great Lakes CCI was managed by the Great Lakes Council and involved representatives from government, industry, landholder and research organisations as well as members of the community. Dr Tony Weber (WBM-BMT) (http://au.linkedin.com/in/tonyrweber)
