The St. Mary’s River is a 120 km-long river that drains Lake Superior into Lake Huron. To allow the safe passage of shipping vessels from Superior to Huron, the Sault locks were built to enable ships to navigate the 21-foot drop between water bodies. Its entire length serves as an international border separating Ontario and Michigan. Aside from its association with international trade and shipping, the river is also widely known as a world-class fishery. It contains resident populations of walleye, bass, perch, whitefish and pike, as well as seasonal populations of steelhead and coho, Atlantic, pink and king salmon.


    The largest freshwater body of water in the world – Lake Superior. The lake and its basin are home to hundreds of species of fish and wildlife, and attracts thousands of visitors each year from across the globe. The largest of the 5 Great Lakes, Lake Superior could contain the volume of the other four Great Lakes within its boundaries.
