But crews are making progress in key areas. Firefighters conducted burnout operations over the weekend and built containment lines along the northeast edge of the fire near Trapper Ridge and a line to further protect the area near Bear Creek, fire managers said.
As of Monday evening, the acreage estimate had not changed and the fire was listed as 40 percent contained. Nearly 1,800 people are fighting the fire, which is expected to be fully contained around the end of September.
Now crews are focusing on cleanup along Highway 21 and on burnout operations down to the South Fork of the Payette River.
Highway 17, aka the Banks-Lowman Road, remains closed between Danskin and Lowman because of fire activity.
The Rough Fire, burning about 14 miles northeast of Lowman, was mapped at 2,332 acres Monday. About 230 people are working on the fire, and the perimeter is about 15 percent contained, according to fire managers.
The smoke from burnout operations and other wildfires in the area is still pushing into the Treasure Valley. The air quality in the Boise area is at a Yellow Alert, meaning sensitive populations like the very young, the very old and people with respiratory conditions, should take precautions and spend less time outdoors, according to the Idaho Department of Environmental Quality.
