The St. Lawrence Seaway is a vital waterway that connects the Great Lakes to the Atlantic Ocean, facilitating trade and commerce between Canada and the United States. To navigate this complex system, it's essential to have access to accurate and up-to-date maps. In this article, we'll explore 10 St. Lawrence Seaway maps that can help make navigation easier for ships, boats, and other watercraft.
Introduction to St. Lawrence Seaway Maps
The St. Lawrence Seaway is a 2,340-mile-long waterway that stretches from the Great Lakes to the Gulf of St. Lawrence. It’s a critical transportation route for goods such as grain, coal, and iron ore, with over 200 million tons of cargo transported through the seaway each year. To ensure safe and efficient navigation, the U.S. and Canadian governments have developed a range of maps and charts that provide detailed information on the waterway’s depth, channels, and obstacles.
