Murray-Darling Basin River Health Assessment Spatial Boundaries

23 valley and 68 zone spatial definitions from the Sustainable Rivers Audit 2 report map the Murray-Darling Basin. The Murray-Darling Basin Authority created these layers for a river health assessment based on fish, macroinvertebrates, vegetation, physical form, and hydrology observations.

Use Cases

• Analyze spatial relationships between the 68 zone definitions and observed hydrology data for catchment management.
• Map the distribution of fish or macroinvertebrate observation data across the 23 valley boundaries.
• Integrate valley and zone spatial layers with vegetation or physical form metrics for ecological health modeling.

Strengths

• Defines 23 distinct valley and 68 zone spatial units for structured basin analysis.
• Authoritative data from the Murray-Darling Basin Authority, the governing body for the region.
• Includes multiple standard geospatial formats (WFS, SHP, GEOJSON, WMS) for interoperability.

Limitations

• Dataset contains only boundary definitions; the actual assessment data (e.g., fish counts) is a separate join.
• Unknown row count and column structure for the underlying attribute tables of the spatial features.
