Western Australian Surface Water Areas and Irrigation Districts

Boundaries for proclaimed Surface Water Areas and Irrigation Districts under the Rights in Water and Irrigation Act 1914 in Western Australia. This dataset consolidates three former datasets for systematic water use management. It is maintained by the Department of Water and Environmental Regulation.

Use Cases

• Analyze spatial boundaries of Irrigation Districts to assess water supply infrastructure planning.
• Map proclaimed Surface Water Areas to regulate watercourse and wetland extraction licensing.
• Integrate boundary data with land ownership records to evaluate irrigation service provision.
• Use the combined dataset to replace legacy RIWI Areas, Irrigation Districts, and Surface Water Area datasets for unified management.

Strengths

• Consolidates three authoritative datasets (RIWI Areas, RIWI Irrigation Districts, RIWI Surface Water Areas) into a single source.
• Provides boundaries defined under specific legislation (Rights in Water and Irrigation Act 1914).
• Offers data in multiple geospatial formats (GEOPACKAGE, WFS, GEOJSON, SHP) for interoperability.

Limitations

• No quantitative data on water usage, licensing, or irrigation activity is included.
• The dataset scope is limited to Western Australia, not applicable to other jurisdictions.
• Sample data and structural details like column names are unavailable for preview.
