Quebec Lake and River Morphology Database

Quebec's Lakes and Rivers Database (LCE) provides detailed information on lakes and waterways across the province. The data includes lake centroids, stream junctions, and lake morphology descriptors such as length, width, depth, volume, elevation, and watershed area. It is intended for applications in environmental science, hydrology, and hydraulics.

Use Cases

• Model hydrological connectivity using lake centroids and stream junctions.
• Analyze lake morphology by correlating depth, volume, and elevation data.
• Estimate watershed-scale water storage capacity from lake volume and watershed area.
• Classify water bodies based on morphological features like length, width, and depth.

Strengths

• Contains detailed lake morphology descriptors including length, width, depth, volume, and elevation.
• Data is sourced from the authoritative Lakes and Rivers (LCE) database maintained by Quebec government entities.
• Includes both point features (centroids, junctions) and area features (watersheds) for hydrological analysis.

Limitations

• Specific row count, column count, and dataset size are unknown.
• Data format includes FGDB/GDB and SQLITE, which may require specialized GIS software to use.
• The description is an automated translation, which may introduce ambiguity in metadata.
