Dominion Energy South Carolina to test sirens at Lake Murray Dam

Lexington, SC - Dominion Energy South Carolina will conduct the annual test of its Lake Murray Dam inundation sirens Tuesday, Jan. 12, at noon. The sirens will sound for approximately three minutes.

The testing is conducted on the second Tuesday of each January. The inundation siren system includes 10 rotating sirens at locations 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.

“Part of our commitment to maintain and monitor the Lake Murray Dam includes taking every precaution to ensure the public’s safety,” said Jim Landreth, Dominion Energy South Carolina Power Generation. “Siren tests help ensure we are prepared for these highly unlikely events.”

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.
