Dataset Number 1027 Dataset Title Surface Water Basins Custodian Data Authority: Department for Environment and Water Data Provider: Department for Environment and Water

Description Description Polygon coverage of the state's Surfacewater basins as defined by the Australian Water Resource Council. Each state was approached to provide basin boundaries which were amalgamated to produce an Australia wide dataset. Usage To delineate each surface water catchment basin within South Australia. Each basin encompasses a number of catchments relating to the stream network they contain.

Data Quality Lineage Maintained by the Department for Water, Land and Biodiversity in 1998. Initially captured under an AWRC program covering Australia. Capture scales varied from 1:10,000 to 1:250,000 for South Australia and was dependent on availability of contoured maps. Completeness Dataset is complete. Positional Accuracy Accurate to the scale of capture. In built up areas the detail is very good. Generally the arid areas of the state were captured at scales of approximately 1:250,000 and boundaries needed interpretation due to the flatness of the areas.
