The River Weaver is a river, navigable in its lower reaches, running in a curving route anti-clockwise across west Cheshire, northern England. Improvements to the river to make it navigable were authorised in 1720 and the work, which included eleven locks, was completed in 1732. An unusual clause in the enabling Act of Parliament stipulated that profits should be given to the County of Cheshire for the improvement of roads and bridges, but the navigation was not initially profitable, and it was 1775 before the first payments were made. Trade continued to rise, and by 1845, over £500,000 had been given to the county.
The Soo Locks are a set of parallel locks, operated and maintained by the United States Army Corps of Engineers, Detroit District, that enable ships to travel between Lake Superior and the lower Great Lakes. They are located on the St. Marys River between Lake Superior and Lake Huron, between the Upper Peninsula of the U.S. state of Michigan and the Canadian province of Ontario. They bypass the rapids of the river, where the water falls 21 ft (6.4 m). The locks pass an average of 10,000 ships per year, despite being closed during the winter from January through March, when ice shuts down shipping on the Great Lakes. The winter closure period is used to inspect and maintain the locks.

To the southwest, across the river, is the United States and the Michigan city of the same name. The two cities are joined by the Sault Ste. Marie International Bridge, which connects Interstate 75 on the Michigan side and Huron Street on the Ontario side. Shipping traffic in the Great Lakes system bypasses the Saint Mary's Rapids via the American Soo Locks, the world's busiest canal in terms of tonnage that passes through it, while smaller recreational and tour boats use the Canadian Sault Ste. Marie Canal.
The Sault Canal Emergency Swing Dam is an all-metal structure built by the Dominion Bridge Company in 1896. It sits along the Canadian Sault Ste. Marie Canal, to protect against the rush of water that would occur if something ever damaged the Sault locks. It operates by swinging over the canal and dropping wicket gates into the water. The Emergency Dam was put to the ultimate test on June 9, 1909, when the freighter Perry G. Walker crashed into the upstream lock sending a torrent of water crashing into the downstream lock. The Perry G. Walker and another ship the "Assiniboia" were sent back into the St. Marys River and another ship that was heading upstream out of the locks the "Crescent City" hit the channel wall. The swing dam proved its worth by slowing down the torrent of water.
The Chicora incident was an incident in May 1870 between the American government and an expeditionary force consisting of British and Canadian militia under the command of Colonel Garnet Wolseley in Sault Sainte Marie. US authorities blocked passage of the Chicora for several weeks, delaying Wolseley's response to the Red River Rebellion. The incident ultimately led to the construction of the Sault Ste. Marie Canal on the Canadian side of the river, allowing unfettered access to the Lake Superior.
