The Dos Patos (center of image) is a shallow tidal lagoon separated from the Atlantic Ocean by a wide sandbar or sandy peninsula. The peninsula has an average width of 15 miles (24 km). Barely discernible and entering the scene from the bottom center (southwest) is a canal or river that flows generally northward from the Mirin Lagoon (not on image) to the city of Pelotas (midway between the left center and bottom left) and empties into the southern portion of the Dos Patos Lagoon.
