Hydrological Map of South America

Our incredibly detailed map of South America shows the inherent beauty of the continent's system of waterways and lakes.  The width of the rivers and streams on the map are determined by their Strahler number which defines their size based on the hierarchy of tributaries. Therefore, the thickness of the lines on the map do not represent the actual size of the waterway.  The lakes on the map are representative of their actual shape and size in reference to the map.  Due to limitations of data and the dimensions of the map, it does not include Greenland, Hawaii, part of the Aleutian Islands, and the Caribbean Islands east of Puerto Rico.
