A fire in Crook County, the Wiley Flat Fire, was first reported on Sept. 2, and began moving quickly, due to wind. The fire was at 100 acres at 3pm and grew to 1,200 acres by 5pm. At that point, fire teams began scooping water from the Ochoco Reservoir in efforts to slow the spread. At 8pm, the fire was up to 5,000 acres.
On Sept. 3, the Central Oregon Type 3 Incident Management Team assumed command of the fire, which was 14,000 acres around 4:30pm, focusing their efforts on structure protection, working to safeguard homes and critical infrastructure in the area.
The cause of the fire is considered to be lightning, according to Central Oregon Fire Info. A temporary evacuation shelter was established on Sept, 2 at the Carey Foster Hall in Prineville.
