Lake Zürich

Lake Zürich is a lake in Switzerland, extending southeast of the city of Zürich. Depending on the context, Lake Zürich or Zürichsee can be used to describe the lake as a whole, or just that part of the lake downstream of the Seedamm at Rapperswil, whilst the part upstream of Rapperswil may be called the Obersee or Upper Lake.

Lake Zürich is formed by the Linth river, which rises in the glaciers of the Glarus Alps and was diverted by the Escher canal into Lake Walen from where its waters are carried to the east end of Lake Zürich by means of the Linth canal . The waters of the Lake of Zürich flow out of the lake at its north-west end, passing through the city of Zürich; however, the outflow is then called the Limmat. The culminating point of the lake's drainage basin is the Tödi at 3,614 metres above sea level.
