Vänern drains into Göta älv towards Gothenburg and the Kattegat opening strait between the Atlantic Ocean’s North Sea and the Baltic Sea. It is the only one of the ten largest lakes in Sweden not to drain out to the eastern coastline. The Göta Canal built in the 19th century forms a waterway that runs to Vättern wholly rising when proceeding eastward, and then a navigable river linking the east coast with Vänern. The main inflow of water comes from Klarälven entering Vänern near Karlstad with its source in Trøndelag in Norway.
