The Upper Liard flood hazard mapping study was completed between May 2025 and March 2026. Learn more by visiting the Yukon Flood Hub. 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).
