This assessment and related data examines water resources in the South Western Plateau region in 2009–10 and over recent decades. Seasonal variability and trends in modelled water flows, stores and levels are considered at the regional level. Details for selected rivers, wetlands, groundwater, urban areas and agriculture are not addressed. At the time of writing, suitable quality controlled and assured information were not identified in the Australian Water Resources Information System (Bureau of Meteorology 2011a). The chapter begins with an overview of key data and information on water flows in the region in recent times followed by a description of the region.
Key data and information
The assessment presents the 2009–10 annual landscape water flows in the South Western Plateau region (no information is available for major storages in the region). The region experienced a slight rainfall deficit for the year, with total evapotranspiration marginally higher than total rainfall, and this contributed to lower than average landscape water yield1 . The dryer conditions for 2009–10 were more dominant on the western side of the region.
