Facts about Mitchell Dam

Mitchell Dam is the second oldest of 14 Alabama Power Company hydroelectric generating plants. The dam was named for James Mitchell, Alabama Power president from 1912 to 1920.

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

A unique feature of the new powerhouse, which was completed in 1985, is a 1,140-foot floating trash boom that deflects trash from the powerhouse intakes.

A fishing facility located below the dam is open year-round to the public. Parking, restrooms, picnic tables and an overlook are also available for public use.
