Ontario Watershed Boundaries and Land Cover Information

Ontario Watershed Information Tool (OWIT) provides geospatial data for calculating information about watersheds in Ontario. The tool, created by the Government of Ontario, enables mapping, watershed characterization, and land cover extraction. It was last updated in February 2026.

Use Cases

• Map watershed boundaries using geospatial polygon data.
• Characterize watersheds by calculating metrics like area and flow accumulation.
• Extract land cover information for analysis of vegetation and urban development.
• Analyze surface water convergence points for hydrological modeling.

Strengths

• Data covers the entire province of Ontario.
• Includes multiple analysis functions: mapping, characterization, and land cover extraction.

Limitations

• Specific row counts, column names, and dataset size are unknown.
• Data is delivered via an HTML tool interface, not a direct data download.
