Southern Lakes flood hazard maps

The Southern Lakes flood hazard mapping study was completed between November 2022 and April 2024. Learn more by visiting the Yukon Flood Atlas. In the Resources section below, you can find the project summary, technical report, “What We Heard” report, GIS data files, and flood maps for specific areas. “AEP” in the flood map filenames below refers to “Annual Exceedance Probability”, the annual likelihood of a flood occurring, expressed as a percentage. The flood scenarios used for mapping in the Yukon are the following: 0.5% event (1-in-200 chance of occurring in any year), 1% event (1-in-100 chance of occurring in any year), and 5% event (1-in-20 chance of occurring in any year).
