Lagoon

Barra Velha is a resort town and county seat of about 20,000 inhabitants in the Northern region of Santa Catarina, Brazil. Its nine beaches extend from the Rio Itapocu in the North to the resort town of Piçarras on its Southern border. Additionally, it is the only resort in the area to have a freshwater lake separated from the ocean by an old sand bar, from which it derives its name.
