SACRAMENTO, Calif. -- Gov. Arnold Schwarzenegger declared a state of emergency in Butte County on Wednesday due to the Ophir and Humboldt wildfires, officials said.

“We are aggressively battling the Ophir and Humboldt Fires, and I thank the hardworking firefighters for their efforts." Schwarzenegger said. "We are mobilizing and coordinating all of the resources necessary to fight these fires.”

The governor directed additional resources to Butte County earlier Wednesday to fight wildfires through Cal Fire and the Office of Emergency Services, including the authorization of DC-10 and DC-7 aircrafts.
