It's nearly as large as Lake Huron, Lake Michigan, and Lake Ontario combined. It also contains approximately 20% of the world's surface freshwater.

The surface area is 12,248 square miles, which makes this lake a tall drink of water. It's hard to imagine how long it would take to walk such a distance. By comparison, the state of North Dakota is about 600 miles wide. Lake Baikal is about seven times as wide as North Dakota.
