Lake Okeechobee (US: / oʊ k i ˈ tʃ oʊ b i / oh-kee-CHOH-bee) [1] is the largest freshwater lake in the U.S. state of Florida. [2] It is the eighth-largest natural freshwater lake among the 50 states of the United States and the second-largest natural freshwater lake contained entirely within the contiguous 48 states, after Lake Michigan.
The largest lake by surface area is Caspian Sea, which is despite its name considered as a lake from the point of view of geography. [79] Its surface area is 143,000 sq. mi./371,000 km 2. The second largest lake by surface area, and the largest freshwater lake by surface area, is Lake Michigan-Huron, which is
Freshwater lakes contain about 87% of this fresh surface water, including 29% in the African Great Lakes, 22% in Lake Baikal in Russia, 21% in the North American Great Lakes, and 14% in other lakes. Swamps have most of the balance with only a small amount in rivers, most notably the Amazon River.
