Surface Water Sustainable Diversion Limit Areas for Basin Plan

29 surface water Sustainable Diversion Limit (SDL) resource units define the boundaries for water take limits under the Basin Plan 2012. The dataset, created by the Murray-Darling Basin Authority, specifies the long-term average annual consumption limits for water diversions within these areas. It was last updated in April 2026.

Use Cases

• Map SDL area boundaries and their associated long-term average annual water take limits using the geospatial polygon data.
• Analyze which geographic regions are excluded from Basin water resources by regulation, as indicated in the dataset metadata.
• Calculate total permissible water diversion volumes by aggregating the SDL values across the 29 defined resource units.

Strengths

• Defines 29 distinct surface water SDL resource units.
• Provides data in 7 formats including SHP and GEOJSON for interoperability.
• Maintained by the authoritative Murray-Darling Basin Authority and updated in 2026.

Limitations

• Unknown row count for attribute tables within the geospatial files.
• Sample data and specific column schemas are unavailable for review.
• Potential for geographic bias as it only covers the Murray-Darling Basin Plan area.
