History of the Soo Locks

History of the Soo Locks

     The Federal Government took control of the property and the lock system in the 1870's.  Their stewardship continues today, administered by the U.S. Army Corps of Engineers.  The Soo Locks are the busiest locks in the world, and include the largest lock in the Western Hemisphere, completed in 1968.

Throughout the colorful history and on into the future, the roots of our heritage go back to  the native residents of the area.                              

                    
The St. Marys River is the only water connection between Lake Superior and the other Great Lakes. There is a section of the river known as the St. Marys Rapids where the water falls about 21 feet from the level of Lake Superior to the level of the lower lakes. This natural barrier through navigation made necessary the construction of the locks project known as the St. Marys Falls Canal.

The world-famous Soo Locks form a passage for deep-draft ships around the rapids in the St. Marys River. Before white men came to the area, the Ojibway Indians who lived nearby portaged their canoes around the "Bawating" (rapids) to reach Lake Superior from the St. Marys River.

Early pioneers arriving in the territory were forced to carry their canoes around the rapids. When settlement of the Northwest Territory brought increased trade and large boats, it became necessary to unload the boats, haul the cargoes around the rapids in wagons, and reload in other boats.

In 1797, the Northwest Fur Company constructed a navigation lock 38 feet long on the Canadian side of the river for small boats. This lock remained in use until destroyed in the War of 1812. Freight and boats were again portaged around the rapids.

Congress passed an act in 1852 granting 750,000 acres of public land to the State of Michigan as compensation to the company that would build a lock permitting waterborne commerce between Lake Superior and the other Great Lakes. The Fairbanks Scale Company, which had extensive mining interests, in the upper peninsula, undertook this challenging construction project in 1853.

In spite of adverse conditions, Fairbanks' aggressive accountant, Charles T. Harvey, completed a system of two locks, in tandem, each 350 feet long, within the 2 year deadline set by the State of Michigan. On May 31, 1855, the locks were turned over to the state and designated as the State Lock.

Boats which passed through the State Lock were required to pay a toll of four cents per ton, until 1877, when the toll was reduced to three cents.

Within a few years, commerce through the canal had grown to national importance, and the need for new locks became clear. The funds required exceeded the state's capabilities, and thus, in 1881 the locks were transferred to the United States government, and were placed under the jurisdiction of the U.S. Army Corps of Engineers. The Corps has operated the locks, toll free, since that time.
