Calgary Water Bodies And Watercourses Map

Hydrological data for Calgary details land covered by intermittent and permanent water bodies, including major natural watercourses like the Bow River and Fish Creek. This generalized dataset is maintained by data.calgary.ca for cartographic purposes and faster rendering. The dataset was last updated in April 2026.

Use Cases

• Map water resource distribution using the FEATURE_TYPE and MULTIPOLYGON columns for spatial visualization.
• Calculate approximate shoreline lengths for environmental studies using the PERIMETER column of water bodies.
• Identify and catalog major natural watercourses like the Bow River by querying the LAKE_NAME column.
• Perform spatial joins with land parcel data using the MULTIPOLYGON geometry for urban planning analysis.

Strengths

• Includes both parcel-bounding and non-parcel-bounding hydrological features.
• Covers multiple major natural watercourses such as the Bow River and Fish Creek.
• Data is generalized for cartographic use, ensuring faster drawing times in GIS applications.

Limitations

• Sample size and total row count are unknown, limiting assessment of coverage.
• Data is generalized, which may reduce spatial precision for detailed analytical work.
• License and authoritative author information are not provided.
