HIDDEN VALLEY LAKE, Calif. – The Hidden Valley Lake area will be part of an emergency notification siren system test planned for Saturday, Aug. 19.

The Lake County Sheriff’s Office reported that the Hidden Valley Lake Association has installed six large emergency sirens that are intended to notify residents of the need for evacuations due to a catastrophic event, whether manmade or natural.

The emergency sirens have been strategically located throughout the Hidden Valley Lake area.

The Hidden Valley Lake Association will be testing the siren system on Saturday at 2 p.m.

There will be two separate activations of the sirens during the test.

Residents are asked not to call 911 or the sheriff's office if they hear the sirens as this is only a test.

The Lake County Sheriff's Office and the Hidden Valley Lake Association are finalizing the procedures for when the sirens will be activated during actual emergencies.

During an actual emergency, Hidden Valley Lake Association will not activate the siren system until they have received permission from the sheriff's office, the California Highway Patrol or another authorized law enforcement agency, according to the sheriff’s office report.
