context_page_description: The Great Lakes or the Great Lakes of North America, are a series of large interconnected freshwater lakes in the upper mid-east region of North America, that connect to the Atlantic Ocean through the Saint Lawrence River. In general, they are on or near the Canada–United States border. They are lakes Superior, Michigan, Huron, Erie, and Ontario. Hydrologically, there are only four lakes, because lakes Michigan and Huron join at the Straits of Mackinac. The lakes form the basis for Great Lakes Waterway.
  The Great Lakes are the largest group of freshwater lakes on Earth by total area, and second-largest by total volume, containing 21% of the world's surface fresh water by volume. The total surface is 94,250 square miles, and the total volume is 5,439 cubic miles, slightly less than the volume of Lake Baikal. Due to their sea-like characteristics the five Great Lakes have also long been referred to as inland seas. Lake Superior is the second-largest lake in the world by area, and the largest freshwater lake by surface area. Lake Michigan is the largest lake that is entirely within one country.
context_section_description: Dispersed throughout the Great Lakes are approximately 35,000 islands. The largest among them is Manitoulin Island in Lake Huron, the largest island in any inland body of water in the world. The second-largest island is Isle Royale in Lake Superior. Both of these islands are large enough to contain multiple lakes themselves—for instance, Manitoulin Island's Lake Manitou is the world's largest lake on a freshwater island. Some of these lakes even have their own islands, like Treasure Island in Lake Mindemoya in Manitoulin Island
