  • Fun Facts
  • Though the five lakes lie in separate basins, they form a single, naturally interconnected body of fresh water, within the Great Lakes Basin.
  • The lakes drain a large watershed via many rivers and contain approximately 35,000 islands.
  • There are also several thousand smaller lakes, often called "inland lakes", within the basin.
  • It is thought the Great Lakes formed through the actions of massive glaciers, and the valleys they carved filled with meltwater from the retreating ice sheets.
