Northern Rockies Complex Incident Management Team 3

#DerbyFire Ops Update Monday morning, Aug. 26, 2025

Operations Section Chief, Philip Knaub, discusses firefighting tactics on the Derby Fire. Due to the weather last night, we were unable to fly an infrared flight to map the fire perimeter. As the rain cleared yesterday afternoon, firefighters were access the southwest and east sides of the fireline and found no significant fire growth. As weather allows today, scouting will continue on the west side of the fire to look for opportunities to build direct fireline from the southwest up. Structure protection efforts continue in the Sweetwater drainage. Structure assessment and protection work will be ongoing along Red Dirt Creek Road on the east side. Firefighters will continue to monitor and assess the fireline to ensure the fire is not progressing.
