Dominion Energy to test inundation siren system for Lake Murray Dam tomorrow

Cayce, SC 01/10/2022 - Dominion Energy South Carolina will conduct the annual test of its Lake Murray Dam inundation sirens Tuesday, Jan. 11, at noon. The sirens will sound for approximately three minutes.

Testing is conducted on the second Tuesday of January. The inundation siren system includes 10 rotating sirens across both 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.

“Siren tests are part of our year-round commitment to the public’s safety,” said Iris Griffin, Vice President, Power Generation for Dominion Energy South Carolina. “These tests help ensure we are prepared even for highly unlikely events as we monitor and maintain the dam.”

The company 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.
