City Mills Dam
The 928th tallest dam in the world
City Mills Dam was a dam on the Chattahoochee River, between Downtown Columbus, Georgia, and Phenix City, Alabama. The dam was built in 1907 to power the City Mills grist mill. Previously, a wooden dam dating to 1828 had existed at the site. The dam impounded a 1.3-mile (2.1 km) run of the river reservoir of approximately 110 acres (0.45 km2). The City of Columbus, Georgia, breached the dam on March 12, 2013, to create an urban whitewater area on the river.
