Alabama Power & SCG Hydro Services will conduct an annual test of the Automated Downstream Notification System tomorrow, November 15, 2022 at around 11:00 AM CDT. The system is used to notify residents immediately downstream of Harris, Lay, Mitchell, Jordan, and Bouldin Dams in the event of an emergency.
The language we use during the test is very clear to convey that it is only a test, and no actual emergency is taking place.
