The Copperfield Fire burning 5 miles southeast of Chiloquin in Klamath County has reached more than 3,600 acres and damaged several structures, including seven primary residences, officials said in a Tuesday morning update.

The fire, which began at about 3 p.m. Sunday, remains 0% contained and has cost more than $500,000, according to data listed in a joint news release from the Oregon State Fire Marshal and Oregon Department of Forestry, the two agencies in unified command of the incident.

“Additionally, representatives of the Klamath Tribe are working with fire officials to ensure protection of cultural sites and assess if any sites were impacted during the first night of firefighting,” the release said.

The release lists the affected residences and structures as “destroyed.” However, it also says Klamath County Emergency Management and OSFM are still assessing the damage.

The cause of the fire, last estimated at about 3,656 acres, is still under investigation, the release said.

A drop in temperatures and a rise in relative humidity allowed fire crews to “make significant progress” on Monday night and Tuesday morning, the release said.

“Today temperatures will begin to warm up, but the high winds firefighters contended with yesterday will significantly calm down. This will allow fire crews to strengthen lines around the fire to try and hold within the present footprint,” the release said. “Structural task forces from Lane, Deschutes, Polk/Marion, Linn, Clatsop and Washington counties will be focused on protecting homes near the fire, mopping up around structures and fortifying critical infrastructure protection measures.”

The agencies reminded people not to fly drones in the vicinity of the fire — doing so could interfere with the helicopters and other air resources working to suppress the blaze. “If you fly, we can’t,” the release said.

As of Tuesday morning, about 286 personnel were working the fire, including people on three hand crews, 36 engines, eight water tenders, seven dozers and four helicopters.

Road closures are still in place from mile marker 5 to 15 on Sprague River Highway.
