COLUMBIA, S.C. — Dominion Energy will conduct its annual test of the inundation siren system at Lake Murray Dam at noon on Tuesday, Jan. 17, 2023.
The test should last about three minutes and includes 10 rotating sirens across Richland and Lexington counties.
The inundation siren system alerts surrounding and downstream areas of the dam if a leak or breach occurs at Lake Murray Dam or its backup dam. Should an actual emergency occur, the sirens would alert the public to tune in to local radio or television stations for information.
This longer test of the system is conducted every January. Dominion also conducts a monthly, one-minute test of the Lake Murray Dam inundation sirens. These tests are a component of Dominion Energy SC’s operation licensure by the Federal Energy Regulatory Commission.
