The Olivehurst Public Utility District has a warning siren that it will be testing on January 6, 2026, at noon that will last between 1 to 3 minutes. The purpose of this siren is to be used in the event of a natural disaster to indicate an evacuation warning and will be used in cooperation and conjunction with other emergency agencies in the area. This warning siren is used to augment other means of warnings to include NOAA All Hazards Weather Radio, law enforcement text notification network, social media, Yuba County Code Red, other broadcast media. Testing will typically take place once per quarter of the year on the first Tuesday in the months of March, June, September, and December at 12:00 p.m. (noon). However, December 2025 will not have a test as the testing will be in January 2026.

The main natural disaster threats to the Olivehurst and Plumas lake areas are flooding from the Feather and Yuba Rivers. However, there are other kinds of natural disasters that can plague our areas like earthquakes, fires, and other unforeseen weather. During the previous natural disaster events that impacted the Olivehurst and Plumas Lake areas, the most recent being in 2017 during the ‘Oroville Dam Crisis’, Yuba County residents experienced a disruption in cellular phone services as there was an overload to the networks. To aid residents in notification of an impending natural disaster that will affect them, OPUD, with the support of Yuba County OES and the Yuba County Sheriff’s Department, has implemented the utilization of a warning siren. This siren will be activated when authorized by local emergency authorities and in coordination with the OPUD Fire Chief indicating that the public should immediately refer to local broadcast media (radio, television, etc.), law enforcement, and/or social media for further information and direction.

Testing of the siren will take place on the first Tuesday in the months of March, June, September, and December at 12:00 pm (noon).
