Allatoona Dam impounds run-off water from 1,110 square miles into the Lake. For an unequalled view of the dam, we recommend a visit to the Operations Project Management Office and Visitor Center which is open Monday through Friday, 8:00 AM to 4:30 PM except holidays. The Visitor Center features video exhibits and displays about the area's history, ranging from the time of early Indians to the gold mining and iron making days, from the Civil War up to the present. Also, to learn how the lake is harnessed for power, be sure to see the animated cutaway drawing of the dam in the Visitor Center at the Operations Project Management Office.
