The Crazy Creek Fire burns in the Ochoco National Forest on Wednesday.

Containment on the Crazy Creek Fire burning in Crook and Wheeler counties reached 5% as of Thursday, according to fire officials.

The 31,000-acre fire started July 22 in the Ochoco National Forest about 16 miles north of Paulina.

A red flag warning went into effect Thursday morning in Crook County due to hot, dry conditions. This means fires may begin spreading more rapidly and move into drier fuels.

New sparks have potential to become bigger fires, according to Crystal Bennese with the National Weather Service in Pendleton.

Firefighters in the area are working to get ahead of the red flag warning conditions. Crews are building containment lines on the north and northeast areas of the Crazy Creek Fire and are working to lay hose near Toggle Meadows to protect areas at risk.

Historic structures and other values on the eastern portion of the Crazy Creek Fire, including Salters Cabin and Wolf Creek Campground are being wrapped with reflective, aluminum materials.

This is to protect structures from damage by reducing impact of heat and block floating embers from igniting structures, according to Cliff Russell, public information officer for the fire.

Fuel and debris in these areas are being cleared to avoid further spread of the fire, said Russell.

The Kitty Creek Fire nearby was 94% contained Thursday at 73 acres, and is currently being monitored as the crews work on containing the Crazy Creek Fire.

Fire crews are holding containment lines and mopping up areas as needed in the southwest portion of the Crazy Creek Fire.

Crook and Wheeler Counties are currently under Level 2 and Level 3 evacuations, according to Russell. The fire team scheduled a meeting for 6 p.m. Thursday Crook County High School to update community members.

“Crews are trying their best to mitigate any more movement,” Russell said.

All public lands, including the Ochoco National Forest are under public use fire restrictions limiting use of fires.

In addition, Russell said there is a temporary flight restriction over the Crazy Creek Fire, meaning recreational drones and other drone operations are prohibited.

According to the National Interagency Fire Center, 32 large fires were burning in Oregon as of Thursday morning. The blazes had burned more than 944,000 acres.
