| | Soo Locks, Sault Ste. Marie, Michigan |
 | | The Soo Locks consist of two canals and four locks: Davis Lock, Poe Lock, MacArthur Lock, and the Sabin Lock (closed), that allow vessels of many types and sizes to safely traverse the 21-foot drop in elevation of the St. Marys River between Lake Superior and Lakes Michigan and Huron. |
 | | The need to build a lock became apparent thus the world-famous Soo Locks were built to form a passage around the rapids in the river. |
 | | As proud stewards of the locks the Army Corps of Engineers, Detroit District operates and maintains the entire facility, at the St. Marys Falls Canal, with the Area Engineer at the Soo Area Office handling immediate supervision of the facilities. |
