Don’t be alarmed if you hear an alarm, Tuesday.

Dominion Energy will conduct its annual test of the Lake Murray Dam alert Tuesday at noon.
The siren tests are part of Dominion’s plan to monitor and maintain the dam.

The sirens will sound for approximately three minutes. The siren system includes ten rotating sirens that are meant to be heeded in Richland and Lexington counties.

Should an actual emergency occur at Lake Murray Dam and its backup dam, the sirens would alert the public to tune in to local radio or television stations for information. The company also conducts a monthly, one-minute test of the Lake Murray Dam sirens. The tests are a component of Dominion Energy SC’s operation licensure by the Federal Energy Regulatory Commission.
