The St. Marys River is a waterway in North America that connects Lake Superior to Lake Huron. It forms part of the border between the United States (Michigan) and Canada (Ontario). The river is approximately 74 miles (119 kilometers) long and is a critical link in the Great Lakes-St. Lawrence Seaway system.
The St. Marys River flows in a southeasterly direction, starting from the eastern end of Lake Superior near the city of Sault Ste. Marie, Michigan, and ending at the northern tip of Lake Huron. It is formed by the confluence of the North Channel and the West Channel, which are both part of Lake Superior.
One of the most significant features of the St. Marys River is the Soo Locks, located in Sault Ste. Marie, Michigan. The locks allow ships to bypass the rapids of the river and navigate between Lake Superior and the lower Great Lakes. The Soo Locks consist of four parallel locks, including the MacArthur Lock, Poe Lock, Davis Lock, and Sabin Lock.
The St. Marys River is a vital shipping route, handling a significant amount of commercial traffic. Freighters and cargo vessels transport various goods, including iron ore, coal, grain, and other bulk commodities, between the upper and lower Great Lakes. The river also supports recreational boating and fishing activities, with anglers targeting species such as walleye, salmon, and trout.
The river and its surrounding area are known for their natural beauty and diverse wildlife. The St. Marys River is home to several islands, including Sugar Island, Neebish Island, and St. Joseph Island, which provide habitats for a variety of plant and animal species. The region is popular among outdoor enthusiasts for activities like boating, kayaking, fishing, hiking, and birdwatching.
Overall, the St. Marys River plays a crucial role in connecting Lake Superior and Lake Huron, facilitating commerce, providing recreational opportunities, and supporting diverse ecosystems. It is an important waterway within the Great Lakes region and contributes to the economic and environmental well-being of the surrounding communities.
