Facts about Lay Dam

Lay Dam was named after Alabama Power Company's first president, Capt. William Patrick Lay. Originally known as the Lock 12 Dam, the facility was later renamed in recognition of Captain Lay's servie to the company and to the public.

Located on the Coosa River, the dam straddles the Chilton and Coosa County line.

Lay Dam was redeveloped during the 1960s as part of the Coosa River project. The project also included the construction of H. Neely Henry, Weiss, Logan Martin and Bouldin dams.
