Great Lakes of North America

The Great Lakes are five large freshwater lakes in North America—Superior, Michigan, Huron, Erie, and Ontario—that collectively form the largest group of freshwater lakes globally by surface area. They are interconnected by rivers and straits, forming a vital waterway for transportation, water supply, and ecological diversity. These lakes support diverse ecosystems, provide drinking water for millions, and sustain industries such as shipping, fishing, and recreation. Their size and interconnectedness influence regional climate patterns and economic activities. The lakes are shared by the United States and Canada, making international cooperation essential for their preservation and sustainable use.
