Firefighters continue building containment across all fires, ODF CIMT 3 to demobilize on Friday, August 21

KIMBERLY, Ore. (Aug. 19, 2026) – Firefighters continue to make steady progress mopping up and building containment on the Bologna, Cottonwood, Little Bear and Rosenbaum fires. Mop-up operations are the methodical and systematic process of identifying and cooling hot spots along the fire’s edge to ensure that heat doesn’t reignite dry vegetation and loft embers outside the fire’s perimeter. Crews also provide suppression repair work to prevent erosion.

Once fires are considered contained, firefighters provide vigilant patrols throughout the summer months to monitor and respond quickly if needed. Local communities can expect to see some smoke in the interior of the fires as unburnt vegetation may ignite. 

The Oregon Department of Forestry Complex Incident Management Team 3 will demobilize Friday, August 21 and return command of the fires to a local type-4 management team and local resources. This will be the last incident update for the Bologna, Cottonwood, Little Bear and Rosenbaum fires.

“We would like to thank the communities for their support and hospitality while we’ve been guests here,” said Incident Commander Tyler McCarty. “We still have half the fire season ahead of us. We have these fires in a place where we can hand them back to local resources, and our folks will go home and be ready for the next time the bell rings.”

This week, incident personnel expect more critical fire weather conditions, such as hot, dry and gusty conditions. This weather, paired with critically dry vegetation, creates conditions where any new fire starts can spread rapidly and likely result in extreme fire behavior. Incident personnel have identified initial attack resources to be prepared to assist local firefighting resources to quickly knock down any news starts. Incident officials urge public caution and ask everyone to follow local fire restrictions to help keep wildfires off the landscape.

Fire restrictions: Officials want to remind everyone that during fire season multiple agencies have restrictions in place to reduce human caused fires, including public use restrictions and limits on equipment use. Check with your local fire service organization before you start the next wildfire.

The Umatilla National Forest issued a temporary closure order for the Bologna Fire on August 11, 2026, which includes portions of Forest Service Roads (FSR) 24, as well as Tamarack Cabin and Lookout. For more information about the closure, visit https://www.fs.usda.gov/r06/umatilla/alerts
