SISTERS, Ore. (August 30, 2025) — The Flat Fire, approximately two miles northeast of Sisters, Oregon, is estimated at 23,380 acres and is now 32% contained. After several days of challenging weather, established control lines have been tested and held strong during recent critical fire weather. Containment continues to increase steadily, a direct reflection of firefighters’ hard work, dedication, and commitment to protecting local communities and the landscape.
Overnight, wildland and structural resources identified, flagged, and addressed hot spots to aid day shift crews with mop-up operations. This coordinated approach ensures each shift is set up for success as hot, dry, and breezy conditions continue this weekend.
Today, wildland resources will continue detailed mop-up operations, while structural crews ensure fire-impacted areas around homes remain secure. Aerial resources will support firefighters by locating any visible smoke, identifying areas that may have lingering heat. On the north and northwestern part of the fire, resources have shifted to suppression repair activities. Repair work includes strategies to reduce the potential for soil erosion.
As the threat to nearby homes and other structures continues to decrease, Oregon State Fire Marshal (OSFM) will gradually transition resources back to their home agencies over the next several days. Although many resources are being released, structural protection is not ending. Firefighters continue to monitor neighborhoods and communities, watching closely for any new hot spots or flare-ups. These crews are ready to respond quickly if conditions change, ensuring that the work already done to protect homes continues to hold.
Firefighter Safety: As holiday weekend traffic increases, and more residents return to affected communities, we ask everyone to remain mindful that fire crews are still working in the area. Please drive carefully, watch for firefighting equipment on the roads, and allow crews space to do their jobs safely.
Wildfire Prevention: If your weekend plans take you outside, please be aware of the fire risks and recreate safely.
