Surface Water Sustainable Diversion Limit Resource Units for the Murray-Darling Basin

Murray-Darling Basin Authority defines the boundaries of 29 surface water Sustainable Diversion Limit (SDL) resource units for the Basin Plan 2012. SDLs set the maximum long-term average annual water consumption limits for each area. The dataset was last updated by the authority in April 2026.

Use Cases

• Map SDL area boundaries using the provided geospatial files (KMZ, GEOJSON, SHP) for regional water planning.
• Analyze the spatial distribution of the 29 SDL resource units to understand regional water entitlement frameworks.
• Calculate long-term average annual water extraction limits per SDL area as defined by the Basin Plan 2012.

Strengths

• Defines 29 distinct surface water SDL resource units for comprehensive basin management.
• Provides data in multiple geospatial formats (KMZ, GEOJSON, SHP, WFS) for interoperability.

Limitations

• Dataset size and row counts are unknown, limiting assessment of granularity.
• Specific column names and attribute data for each SDL unit are not detailed in the description.
