Lagoa dos Patos
Lake Brazil's largest lagoon, brackish coastal waterbody
A vast coastal lagoon in Rio Grande do Sul, Lagoa dos Patos is Brazil’s largest lagoon; visitors and locals use it for fishing, boat travel and wildlife observation along sandy barrier shores.
Lagoa dos Patos is a large coastal lagoon in the state of Rio Grande do Sul, Brazil, and is the country’s largest lagoon. The body of water forms an extensive estuarine system important for fisheries, wildlife and regional navigation.
The lagoon has brackish water influenced by freshwater inflows and tidal exchange with the Atlantic Ocean through a channel near the city of Rio Grande. Its shores support coastal settlements, marshes and areas used for fishing and aquaculture.
The lagoon has long been used by local communities for fishing and transport; over time port infrastructure developed at its outlets to serve regional commerce. It remains a significant ecological and economic feature of southern Rio Grande do Sul.
Lagoa dos Patos stretches along the coast of Rio Grande do Sul in southern Brazil, with the state capital Porto Alegre and other coastal towns located on or near its northern reaches. The lagoon is separated from the open Atlantic by a sandy barrier along much of its eastern side.
