Tortuguero Lagoon


Laguna Tortuguero Nature Reserve is a protected area located between the municipalities of Vega Baja and Manatí in Puerto Rico, containing Laguna Tortuguero, the largest freshwater lagoon in the island.
The lagoon is one of only two natural freshwater lakes in the island of Puerto Rico, and is home to an ample variety of species.

General information

Tortuguero Lagoon contains about 708 million gallons of water. The reserve was designated in 1979 through a program of Coastal Zone Management of Puerto Rico. It is located between the municipalities of Vega Baja and Manatí and covers approximately.
It is divided into two main parts: in the east and northeast, the Laguna Grande, and in the south, the Laguna Rica. A swamp located northeast of the pond, Cabo Caribe, includes one of the most important areas of the reserve as a source of nesting and feeding waterflow ecosystem.
Generally, Tortuguero is made up of swamps, marshes, soils of silica sand and hills. Although not a forest, its variety of rare endemic plants and flowers has earned it a place amongst the most important reserves in Puerto Rico, just after El Yunque, Toro Negro State Forest and the Forest of Maricao.
