This assessment and related data examines water resources in the Lake Eyre Basin 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 was not identified in the Australian Water Resources Information System (Bureau of Meteorology 2011a). It 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 Lake Eyre Basin region (no information is available for major storages in the region). The region experienced very much higher than average rainfall in 2009–10 and this high level of water availability also resulted in very much above average levels of evapotranspiration and landscape water yield1.
