The largest bodies of water include oceans, seas, gulfs, bays, and lakes. The charts show the largest bodies of water, including Lake Chad’s significant size reduction. The first graph shows the largest saltwater bodies, including the Southern Ocean. Lake Superior is the largest freshwater lake, and most of the largest lakes are in North America.
The largest bodies of water in the world include oceans, seas, gulfs, bays and lakes. While there is no agreement on the precise size, as the boundaries of the water bodies are unclear, the charts below include some of the largest. Also noteworthy are the dimensional variations due to natural and unnatural causes. Lake Chad is worth mentioning in this regard. With an area of over 9,653 square miles (25,000 square km) in the 1960s – about the size of Lake Erie – Lake Chad was Africa’s fourth largest lake. In the late 1990s, this lake had an area of just 521 square miles (1350 square km), about 1/3 the size of the Great Salt Lake in Utah.
The first graph is limited to saltwater bodies. It includes the Southern Ocean, recognized in 2000 by the International Hydrographic Organization as the fifth largest ocean in the world, joining the Pacific, Atlantic, Indian and Arctic oceans. As the graph shows, it is the fourth largest of these five oceans.

Lake Superior, one of the Great Lakes, is the largest freshwater lake. The other Great Lakes are also among the largest freshwater lakes in the world. The Caspian Sea, although technically a lake, contains salt water. Interestingly, most of these lakes are in the Northern Hemisphere and most of them are in North America.
