Regional Surface Hydrology Polygons for Australia

Geoscience Australia aggregated the best available jurisdictional data to produce this geometric representation of major hydrographic polygon elements. It includes both natural and artificial features intended for defining hydrological attributes. The dataset was last updated in April 2026.

Use Cases

• Map and analyze the distribution of lakes and reservoirs using polygon geometry and feature class attributes.
• Model watershed boundaries and connectivity by joining hydrological polygon features based on shared attributes.
• Assess regional surface water coverage by analyzing the spatial extent and type of hydrographic polygon elements.

Strengths

• Data represents the best available information supplied by Australian jurisdictions.
• Provides a consistent basis for hydrological information production across regions.
• Includes both natural and artificial hydrographic features.

Limitations

• Specific row counts, column details, and sample data are unavailable for assessment.
• The dataset's internal accuracy, completeness, and recency relative to source updates are unknown.
• License terms are unspecified, which may restrict use cases.
