Lake Superior and Lake Michigan are indeed connected through a series of rivers, canals, and the Great Lakes Seaway Navigation System. This connection plays a crucial role in the regional economy, enabling the transportation of cargo and goods between the lakes and the Atlantic Ocean.
The Direct Connection
The connection between Lake Superior and Lake Michigan is a direct one. Lake Superior drains into Lake Huron via the St. Mary’s River, and Lake Huron is directly connected to Lake Michigan through the Straits of Mackinac. This hydrological connection allows water to flow from one lake to another, with Lake Superior being at a higher elevation than Lake Michigan.
The Great Lakes Seaway Navigation System
The Great Lakes Seaway Navigation System is a network of locks, channels, and canals that facilitate navigation between the Great Lakes and the Atlantic Ocean. This system includes the Soo Locks, which connect Lake Superior to Lake Huron, and the St. Lawrence Seaway, which connects Lake Ontario to the Atlantic Ocean.
The Soo Locks
The Soo Locks, located on the St. Mary’s River, are a crucial component of the Great Lakes Seaway Navigation System. These locks allow ships to bypass the rapids on the St. Mary’s River, enabling safe passage between Lake Superior and Lake Huron.
The St. Lawrence Seaway
The St. Lawrence Seaway is another essential part of the Great Lakes Seaway Navigation System. This system of locks, canals, and channels connects Lake Ontario to the Atlantic Ocean, providing a vital shipping route for cargo and goods.
Water Level and Elevation
The connection between Lake Superior and Lake Michigan is not only physical but also hydrological. Lake Superior is at a higher elevation than Lake Michigan, with a drop of approximately 21 feet between the two lakes. This difference in elevation is managed through the system of locks and dams that make up the Great Lakes Seaway Navigation System.
Navigational Routes
The primary navigational route between Lake Superior and Lake Michigan is through the St. Mary’s River and the Soo Locks. This route allows ships to bypass the rapids on the St. Mary’s River and navigate safely between the two lakes. Additionally, there are other navigational routes, such as the Detroit River and the St. Clair River, which connect Lake Huron to Lake Erie and Lake Michigan, respectively.
Economic Importance
The connection between Lake Superior and Lake Michigan is crucial for the regional economy. The Great Lakes Seaway Navigation System enables the transportation of cargo and goods, including iron ore, coal, grain, and other commodities, between the lakes and the Atlantic Ocean. This transportation network supports a significant portion of the regional economy, contributing to the prosperity of the surrounding communities.
Conclusion
In conclusion, Lake Superior and Lake Michigan are indeed connected through a series of rivers, canals, and the Great Lakes Seaway Navigation System. This connection is vital for the regional economy, enabling the transportation of cargo and goods between the lakes and the Atlantic Ocean. The system of locks, channels, and dams that make up the Great Lakes Seaway Navigation System play a crucial role in managing the water levels and elevations between the lakes, ensuring safe and efficient navigation.
