On June 23, a vegetation fire started on Pawnee Road and New Long Valley Road, northeast of Clearlake Oaks in Lake County.

According to the California Department of Forestry and Fire Protection, the Pawnee Fire burned 15,185 acres and destroyed 22 structures.

Governor Brown declared a state of emergency in Lake County on June 25. The cause of the fire is unknown.
