Western Australia Surface Water Allocation Subareas

WRIMS subareas define hydrographic catchments for water management in Western Australia. Department of Water and Environmental Regulation officers delineated boundaries based on similar management requirements and future concerns. The data supports sustainable yield calculations and includes native vegetation clearing values for the South-West region.

Use Cases

• Calculate sustainable yields and flow rates for water allocation decisions using subarea boundaries.
• Integrate native vegetation clearing values from the South-West region into water allocation planning.
• Analyze management subareas derived from hydrographic catchments to identify regions with notable water concerns.
• Support natural resource management decisions with geometry-based allocation subareas.

Strengths

• Data developed in consultation with regional Department of Water and Environmental Regulation officers.
• Includes native vegetation clearing values calculated for subareas within the South-West region.
• Available in multiple geospatial formats including GeoJSON, SHP, and Geopackage.

Limitations

• Specific row count, column details, and total spatial extent are unknown.
• Data scope is limited to Western Australia, specifically the South-West region for vegetation metrics.
