How to Report a Wildfire

A wildfire is any fire burning out of control in forests, grasslands,
or brush. All citizens are asked to report such fires immediately. If
you see a wildfire: CALL 1-800-777-FIRE (3473).

Be prepared to give the dispatcher:

Your name
Your telephone number
The specific location of the fire
Any other information that might be helpful.

When reporting any emergency, try to be calm and speak clearly.

Wildfires can also be reported to 911 if that service is available in
your county.
