Permafrost thaw is expected to cause catastrophic lake drainage and potential debris flow in 2015.
A rapid flow of water and debris is expected in a small creek valley west of Husky Lake, which lies in the Gwich' in Settlement Area (GSA). The growth of a permafrost thaw slump will likely cause a small lake to drain catastrophically during 2015, resulting in a flash flood and possibly a debris flow. A flash flood could happen at any time during the summer or fall of 2015.
The area of potential impact is outlined in red on the map and three hazardous areas include:
Hazard Area 1: Traveler's Cabin at north end of Husky Lake
Hazard Area 2: Lake north of Husky Lake
Hazard Area 3: Permafrost thaw slump next to small lake
Be aware of the potential risk of a flash flood. Avoid camping or traveling in this area. There is no warning system in place. The lake and slump will be monitored as part of a NTGS permafrost research project.
