Southern Lakes Flood Hazard Maps for Yukon with Annual Exceedance Probability

Completed between November 2022 and April 2024, this dataset contains flood hazard maps for the Southern Lakes region of Yukon, Canada. The maps model flood scenarios for 0.5%, 1%, and 5% Annual Exceedance Probability events. The dataset includes GIS data files, technical reports, and summaries from the Government of Yukon.

Use Cases

• Model flood inundation extents based on the 1-in-200, 1-in-100, and 1-in-20 year probability scenarios
• Plan infrastructure and land use based on GIS flood hazard maps
• Assess community risk by integrating flood maps with demographic or property data

Strengths

• Includes three defined flood probability scenarios (0.5%, 1%, 5% AEP)
• Provides multiple file formats including GIS-ready SHP and FGDB files
• Associated with 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
