The John C. Stennis Lock and Dam, formerly named Columbus Lock and Dam, is one of four lock and dam structures on the Tennessee-Tombigbee Waterway that generally lie along the original course of the Tombigbee River. It is located near Columbus, Mississippi, and impounds Columbus Lake. It is named for longtime U.S. Senator from Mississippi, John C. Stennis.{{cite web|url=http://www.tenntom.org/about/ttwkeycomponents.htm|title=About the Tenn-Tom Waterway: Waterway Description and Components|date=2009-11-26|work=Tennessee-Tombigbee Waterway Development Authority|access-date=2007-04-28|archive-url=https://web.archive.org/web/20090727231639/http://www.tenntom.org/about/ttwkeycomponents.htm|archive-date=2009-07-27|url-status=dead}}{{cite web | url={{Gnis3|690832}} | title=Columbus Lock and Dam | work=Geographic Names Information System | publisher=United States Geological Survey | accessdate=2006-05-02 }}
