#DerbyFire Ops Update Monday morning, Aug. 25, 2025
Operations Section Chief, Philip Knaub, discusses firefighting tactics on the Derby Fire. With the wet weather yesterday, we do not expect to see growth in fire acreage from Sunday afternoon August 24 moving into Monday morning August 25, 2025. The weather did not allow for an overnight infrared flight, which maps the fire’s perimeter and informs changes in fire acreage. However, prior to the rain, firefighters were able to continue to work on the west, southwest, south, southeast and eastern edges of the fire. Hotshot crews continue to build direct line on the west/southwest fire edge near the Hack Creek drainage. Firefighters will be assessing opportunites to build direct line along the fire edge east of where burnout operations were conducted earlier this week near the Horse Creek drainage. Where the previous fire growth has been on the southeastern side of the fire, firefighters progressed in constructing handline and dozer line along the fire edge, supported by aerial retardant drops. Fire behavior on the east side of the fire was moderate and crews will continue to build indirect fireline, assessing opportunities to go direct.
