Lake County Sheriff’s Office Conducting Test of Emergency Sirens on February 7th


The following is a press release issued by the Lake County Sheriff’s Office:

On Monday, February 7, 2022, at 11:00 am, the Lake County Sheriff’s Office will conduct a full-length test of the warning sirens in Middletown, Anderson Springs, Cobb, Loch Lomond, and Kelseyville Riviera (formerly known as the Clear Lake Riviera). The test will last three minutes. In the event of an actual emergency, the warning siren is one way the community may be alerted to danger from wildfire, earthquake, or other hazards.  

Ongoing monthly testing for the sirens will occur on the first Monday of each month at 11:00 am. The testing from March through January will be 30-second tests. The February test each year is the full three-minute activation. Just prior to each test, messaging will be sent out through LakeCoAlerts and Nixle notifying residents in the area of the sirens of the test. 

When the sirens are heard outside of a scheduled test, community members should take shelter, be vigilant, and look for further information and instructions from LakeCoAlerts and Nixle. The sirens may not be heard depending on topography, natural and manmade noise, if residents are indoors, or potentially too far aware from the sirens. 

The Middletown, Anderson Springs, Cobb, and Loch Lomond sirens have been in place since 2018. These sirens are owned and maintained by the South Lake Fire Protection District. Since these sirens have been installed, they have only undergone monthly 30 second tests to ensure their functionality. Over the past year, many residents expressed a desire to have a full three-minute test conducted to ensure residents know what the siren will sound like in the event of an emergency. 

In the summer of 2021, the Kelseyville Riviera Home Owners Association installed three warning sirens to provide another form of warning to their residents in the case of an emergency. As these are new sirens, their functionality has not been tested. This will be the first test of the warning sirens in the Kelseyville Riviera. Should there be any issues, please contact the Kelseyville Riviera Home Owners Association at

The Lake County Sheriff’s Office encourages all residents of Lake County to sign up for LakeCoAlerts at:
