Mesoamerica [SEP] Bodies of water
Additionally, no lakes exist in the northern peninsula. The main source of water in this area is aquifers that are accessed through natural surface openings called cenotes. With an area of 8,264 km (3,191 sq mi), Lake Nicaragua is the largest lake in Mesoamerica. Lake Chapala is Mexico's largest freshwater lake, but Lake Texcoco is perhaps most well known as the location upon which Tenochtitlan, capital of the Aztec Empire, was founded. Lake Petén Itzá, in northern Guatemala, is notable as where the last independent Maya city, Tayasal (or Noh Petén), held out against the Spanish until 1697. Other large lakes include Lake Atitlán, Lake Izabal, Lake Güija, Lemoa, and Lake Managua.
