Catchment areas and watersheds
Primary watersheds, also known as main European watersheds, are the boundaries between the catchment areas of rivers that flow into the seas around the Continent of Europe. Most of Switzerland (from the crest of the Alps to the north) drains into the Rhine (27,823 km²); the Rhone mainly collects water from the Canton of Valais, the Lake Geneva area and the Ajoie (7,691 km²); the Po collects water
