COEUR D’ALENE, ID – The Sunset Fire, burning on the western slope of Lake Pend Oreille about 25 miles north of Coeur d’Alene, has reached 3,230 acres and is 42 percent contained, according to the latest update from fire officials.

The fire, which started on August 13, remains under investigation. Northern Rockies Team 5, under Incident Commander Joe Sampson, reported 643 personnel assigned to suppression efforts.

The Bonner County Sheriff’s Office has lifted all “GO” evacuation levels for the Sunset Fire. Some roads in Talache and access to Talache remain in “SET” status. Details are available on InciWeb. Maiden Rock Campground on the western shore of Lake Pend Oreille is closed until further notice.

Crews reported progress Monday. A type 2 hand crew and a hotshot crew completed fireline construction on the southeastern edge near the lake and worked to secure and mop up hot spots. On the southern and western flanks, firefighters used pumps, hoselays, and sprinklers to address residual heat. Hotshot crews also completed fireline work on the northern edge of the perimeter, where a small one-tenth acre slop-over was quickly contained and extinguished.

Helicopters supported suppression with water drops and supply deliveries. Watercraft on the lake shuttled crews and provided logistical support and lookouts. An unmanned aircraft system equipped with infrared sensors identified hotspots and areas of residual heat for firefighters.

Weather conditions remain challenging. Temperatures reached the low 90s with relative humidity in the teens on Monday. Winds ranged from 5 to 10 mph along the lakeshore and ridgetops, with gusts up to 15 mph, decreasing in the afternoon. Poor overnight humidity recovery is expected to continue through mid-week, leading to longer burn windows into the evening.

Officials said fire behavior may include flanking, torching, flare-ups, and short-range spotting, primarily within the existing perimeter where unburned fuels continue to smolder.
