The Inner Harbor Navigation Canal Lock—commonly known as Industrial Canal Lock or simply Industrial Lock[1]—is a navigation lock in New Orleans. It connects the Lower Mississippi River to the Industrial Canal and other sea-level waterways. Because it is shorter and narrower than most modern locks on the Mississippi River System, the 1920s vintage lock has become a bottleneck between the nation's two highest-tonnage waterways—the Mississippi and the Gulf Intracoastal Waterway.[2]
The lock is located at Lower Mississippi River mile 92.6 AHP. Owing to the confluence of multiple waterways at the Industrial Canal and Lock, the lock chamber is also considered mile 6 EHL (east of Harvey Lock) on the Intracoastal and mile 63 on the Mississippi River-Gulf Outlet Canal.
Although the depth over the sill is 9.6 meters (31 feet), most of the traffic through the lock consists of shallower-draft barge tows transiting the Intracoastal.[3]
