New Lock at the Soo

This image is an Artist Rendition that illustrates what it might look like if a Second Poe-Sized Lock replaced two of the older locks (left portion of the photo). The Poe Lock, opened in 1969, was the last lock built in the Soo Locks system, the only passage between Lake Superior and the lower lakes.

The Soo Locks facility, operated and maintained by the U.S. Army Corps of Engineers, Detroit District, is the District’s largest project and is located on the St. Marys River at Sault Ste. Marie, Mich. on the international border with Canada. Approximately 80 million tons of commercial commodities pass through the Soo Locks annually.


Soo Locks Hydro Plant Tail Race Closures

The Soo Locks Hydro Plant Tail Race is currently open until a date to be determined in Spring 2024. The tail is expected to be closed Spring-early winter of 2023 and 2024.

The closure is necessary as New Lock at the Soo construction will have many large marine-based construction barges and equipment in the area, causing an unsafe area for recreational boaters. 

To be added to the Tail Race alert notification system, contact 906-259-2841.
