Lagoa dos Patos

Lagoa dos Patos (Portuguese pronunciation: [laˈɡo.ɐ dus ˈpatus], [lɐˈɡow.wɐ], locally [laˈɡo.ɐ dos ˈpatʊs]; English: Ducks' Lake) is the largest lagoon in Brazil and the largest barrier-lagoon in South America.[1] It is located in the state of Rio Grande do Sul, southern Brazil. It covers an area of 10,000 km2 (3,900 sq mi),[1] is 174 miles (280 km) long and has a maximum width of 44 miles (60 km).

Lagoa dos Patos is separated from the Atlantic Ocean by a sandbar about 5 miles (8 kilometers) wide. The Jacuí-Guaíba and Camaquã Rivers empty into it, while the navigable São Gonçalo Channel, which enters Lagoa dos Patos near the town of Pelotas, connects Lagoa dos Patos to Lagoa Mirim to the south.[1] The Rio Grande, at the south end of Lagoa dos Patos, forms the outlet to the Atlantic.[1]

The most accepted etymology is that the name "Patos" comes from an indigenous tribe that used to live in the area when the Europeans arrived.

This lagoon is evidently the remains of an ancient depression in the coastline shut in by sand beaches built up by the combined action of wind and current. The shallow lagoon is located at sea level, but its waters are affected by the tides and are brackish only a short distance above the Rio Grande outlet.[1]

The lagoon's largest and most fertile island is the Ilha dos Marinheiros, which is located near the eastern shore. The island is geopolitically part of the municipality of Rio Grande.

The lagoon hosts a rich biodiversity, including fresh- and brackish water fish, and water birds such as black-necked swan, coscoroba swan and Chilean flamingo.[1] Top predators from ocean ecosystem, notably common bottlenose dolphins, can sometimes be seen at Lagoa dos Patos[2][3] and exceptionally southern right whales are found at the Rio Grande outlet.[4][5]
