The Butte County Sheriff's Office has partnered with Avtex Incorporated for their Community Notification System.
The CityWatch system is online and can be accessed by the Sheriff's Department during an emergency for the protection of the public.
The portal below can be used by the public to add Cellular phone numbers and email addresses to the system to be used during emergency notifications. The system already has listed and unlisted hard line phone numbers for all of Butte County
