Ontario Aquatic Resource Areas with Fish Species Data

Aquatic resource area polygon segments represent portions or entire water bodies like lakes, rivers, and streams across Ontario. The dataset is the authoritative source for generic spatial data on fish species in the province, maintained by the Government of Ontario. It was last updated in March 2026.

Use Cases

• Analyze water temperature and depth attributes for habitat suitability modeling of specific fish species.
• Map fish species observations across lakes and rivers to support municipal and natural heritage planning.
• Use polygon segment locations for issuing work permits under the Public Lands Act.
• Identify water body segments for issuing licenses under the Fish and Wildlife Conservation Act.

Strengths

• Authoritative source for fish species spatial data in Ontario.
• Includes attributes for physical characteristics like water temperature and depth.

Limitations

• Sensitive data for provincially tracked species and species at risk is excluded.
• Specific row counts and spatial extents are not provided in the description.
