Quebec Lake Bathymetry Data from Government and Partners

A 2026-updated geospatial base consolidates lake depth measurements produced by or shared with Quebec's Ministry of the Environment and Climate Change. It harmonizes data from multiple government units and external contributors like regional councils and universities. The dataset is available in multiple formats including GeoJSON, CSV, and GPKG.

Use Cases

• Model lake volume and water storage capacity using bathymetric depth measurements.
• Analyze spatial distribution of bathymetric data across Quebec's lakes for coverage assessment.
• Integrate bathymetry with other aquatic environmental datasets using GeoJSON or GPKG formats.

Strengths

• Includes data from multiple authoritative contributors like the Quebec government and the University of Montreal.
• Available in six interoperable formats including GeoJSON, CSV, and GPKG for flexible use.
• Actively maintained with a last update in March 2026 and a process for public data contribution.

Limitations

• Specific data volume metrics like row count, file size, and spatial resolution are unavailable.
• Column schema is unknown, complicating initial data exploration and analysis planning.
