Upper Murrumbidgee Catchment Boundary for Waterwatch, ACT Region

ACT Government Geospatial Data Catalogue provides the boundary of the Upper Murrumbidgee Catchment for Waterwatch. The feature layer maps the approximate boundary based on a 30-second DEM hydrology model in the GDA2020 coordinate system. The dataset was last updated on April 4, 2026.

Use Cases

• Define watershed boundaries for hydrological modeling based on the catchment boundary.
• Assess water quality monitoring program coverage based on the Waterwatch catchment area.
• Integrate catchment data with other geospatial layers for regional environmental planning.
• Validate local watershed flow direction models against the provided boundary.

Strengths

• Based on a 30-second DEM hydrology model, suggesting a specific resolution.
• Provides data in multiple geospatial formats including GeoJSON, GPKG, and ArcGIS REST API.
• Last updated on April 4, 2026, indicating recent maintenance.

Limitations

• The boundary is approximate, and local differences in watershed direction are expected.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
