Dawson City/Klondike Valley Flood Hazard Maps for Three Annual Exceedance Probabilities

The Dawson City/Klondike Valley flood hazard mapping study was completed by the Government of Yukon between May 2024 and March 2026. It includes GIS data files and flood maps modeling three flood scenarios: 0.5%, 1%, and 5% Annual Exceedance Probability (AEP) events. Resources include a project summary, technical report, and community feedback report.

Use Cases

• Model flood risk exposure for infrastructure based on Annual Exceedance Probability (AEP) scenarios.
• Plan land use and zoning regulations based on flood hazard maps.
• Assess insurance and emergency preparedness for areas defined by 1-in-20, 1-in-100, and 1-in-200 year flood probabilities.

Strengths

• Includes GIS data files (SHP, GDB) for spatial analysis.
• Models three specific flood scenarios (0.5%, 1%, and 5% AEP) with defined probabilities.
• Supported by a technical report and community feedback ('What We Heard') report.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
