Western Australia Surface Water Management Areas

Western Australia's surface water resources are divided into management areas for licensing and administrative control. The Department of Water and Environmental Regulation defines these areas based on hydrographic subcatchments and regional management requirements. Data is provided in multiple geospatial formats including GeoPackage, GeoJSON, and Shapefile.

Use Cases

• Delineate hydrographic subcatchment boundaries for environmental water requirement modeling.
• Analyze surface water management area geometries for regional licensing and extraction oversight.
• Integrate surface water area polygons with other hydrological datasets using provided geospatial formats.

Strengths

• Data is provided in 8 distinct geospatial and service formats, including GeoPackage, WFS, and GeoJSON.
• Managed and published by the authoritative state Department of Water and Environmental Regulation.
• Boundaries were derived in consultation with regional offices to reflect local management needs.

Limitations

• The dataset lacks explicit row or feature count metrics, limiting assessment of its scale.
• Sample data and specific attribute columns are unavailable for preview.
• The custom_active_acceptance license requires explicit review and acceptance before use.
