(Fremont County, WY) – The Wyoming Bureau of Land Management has shared that, as of today, August 13, the Weiser Knoll Fire is 51% contained, with the total acreage remaining at 16,351 acres.
The 51% containment was reached yesterday following substantial progress and perimeter gains along the north side of the fire, according to the BLM’s latest update.
Multiple ground resources remain actively engaged on the line today and are continuing mop-up operations throughout the fire area to ensure established containment lines hold. (Mop-up operations involve firefighters systematically cooling hot spots and extinguishing smoldering debris along the perimeter to prevent spot fires outside the line.) A Type 1 helicopter remains on site to support ground personnel with targeted water drops on active heat as needed.
Today’s update also includes the following closure, safety, and weather information:
- Current Evacuation orders are still in effect – updates are available on the Fremont County – Wyoming – Emergency Management Agency Facebook page.
