The nearly 1.15 million hectare catchment is geographically diverse with its western portion on the Swan Coastal Plain encompassing high quality coastal dune and lake environments, the largest estuarine system in the south west, and an extensive backplain and foothills area. The coastal plain portion of the catchment supports many relatively small sized farms and areas of irrigated horticulture. It also includes the rapidly growing City of Mandurah and southern parts of the Perth metropolitan region with the associated urban, peri-urban, and industrial land uses. Beyond the coastal plain, the central and eastern portions of the catchment within the Darling Plateau extend through a large expanse of State forest and conservation reserves centred around Dwellingup to the ‘broad-acre’ agricultural areas of the wheatbelt near Narrogin.
