City Mills Dam

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 mi run of the river reservoir of approximately 110 acre.

The City of Columbus, Georgia, breached the dam on March 12, 2013, to create an urban whitewater area on the river.
