St Mary's River

St. Mary's River is a vital waterway connecting Lake Superior and Lake Huron, serving as a natural border between the United States and Canada. Flowing approximately 74 miles (119 kilometers), the river is home to the famous Soo Locks, a system of locks and canals that enable ships to navigate the 21-foot (6.4 meters) elevation difference between the two lakes. This engineering marvel plays a crucial role in facilitating maritime trade between the Great Lakes and beyond. The St. Mary's River is not only an essential transportation route but also offers picturesque views and recreational opportunities for boaters, anglers, and nature enthusiasts who appreciate its beauty and significance.
