Laguna de Términos
Laguna de Términos is the largest and one of biologically the richest tidal lagoons located entirely on the Gulf Coast of Mexico, as measured by water volume. Exchanging water with several rivers and lagoons, the Laguna is part of the most important hydrographic river basin in Mexico. It is important commercially, as well as ecologically by serving as a refuge for an extensive number of flora and fauna; its mangroves provide an important role as a refuge for migratory birds.
The Boca de Terminos was discovered during Juan de Grijalva's expedition in 1518.
Laguna de Términos (Términos Lagoon) is made up of a series of rich, sediment-laden lagoons and tidal estuaries connected by two channels to the Bay of Campeche in the southern part of Gulf of Mexico, in Carmen Municipality in the southwestern part of the Mexican state of Campeche. Its shores are swampy and support mangroves. It is fed by several freshwater rivers, including the Mezcapala, Grijalva and Usumacinta Rivers, and includes several lagoons such as Pom, Atasta, Puerto Rico, Este and Panlau. It is 72 km (45 mi) long, 24 km (15 mi) wide, and covers an area of 1,550 km2 (600 sq mi). Every nine days, approximately 50% of the lagoon's water volume is renewed, primarily through the effect of ocean tides.
On the surrounding barrier islands, beach ridges, and mangrove coastline there are several Late Postclassic Maya sites. The city of Ciudad del Carmen is located on Isla del Carmen, between the lagoon and the Bay of Campeche.
