The River Itapocu flows eastward from the planalto or highlands of Northeastern Santa Catarina, Brazil, to the Atlantic Ocean. Passing through the industrial city of Jaraguá do Sul, it feeds a lake in Barra Velha before reaching the sea. At its terminus, it forms the boundary between the municipalities of Barra Velha and Araquarí.
