The Great Lakes

from: https://en.wikipedia.org/wiki/Great_Lakes

The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes in the east-central interior of North America that connect to the Atlantic Ocean via the Saint Lawrence River. The five lakes are Superior, Michigan, Huron, Erie, and Ontario and they are in general on or near the Canada–United States border.

The Great Lakes are the largest group of freshwater lakes on Earth by total area and are second-largest by total volume, containing 21% of the world’s surface fresh water by volume.
