Of tectonic origin and with an area of 8,264 km², it is the largest fresh water lake in Central America, the 19th largest lake in the world and the tenth largest in the Americas, slightly smaller than Lake Titicaca. With an elevation of 32.7 metres above sea level, the lake reaches a depth of 26 metres. The intermittent Tipitapa River feeds Lake Nicaragua when Lake Managua has high water. Lake Cocibolca is between two other bodies of water, on top is Lake Xolotlán and below is the San Juan River. These body of waters complete the largest International Drainage Basin in Central America.
