Lock Closures / Locking Through

As the operator and maintainer of locks on several major waterways in the southeast, the U.S. Army Corps of Engineers, Mobile District, is the primary point of contact when requesting to “lock through”.

Please follow the directions of the lock operator when using the locks or operating in the vicinity of the locks. Lock operator has final authority on the suitability of a craft for lockage.

Neither passengers nor freight may be loaded or unloaded at locks. The order of passage through the lock is at the discretion of the lock operator. The boat arriving first usually will be locked through first, but there are exceptions.

Always check our Lock Maintenance and Closure schedule before planning your trip on any of the Mobile District’s waterways. We routinely close locks for maintenance and post an updated schedule regularly to alert the public.
