Lake Zurich is a lake in Switzerland, extending southeast of the town of Zurich. It is also known as Lake Zürich and Lake of Zürich. Zürichsee is strictly the name of the part of the lake downstream of the dam at Rapperswil, mostly located within the canton of Zurich. The part upstream of the Rapperswil dam is called Obersee, and is shared between the cantons of St. Gallen and Schwyz. Geographically, Lake Zurich is located in the southwestern part of the canton of Zurich. To the east are – separated by Zürichberg-
Lake Zurich is formed by the river Linth, which, rising in the glaciers of the Tödi Range in Glarus, which was diverted by the Escher canal (completed in 1811) into the Lake Walen, there by means of the Linth canal (completed in 1816), its waters are carried to the east end of the Lake of Zurich. The waters of the Lake of Zurich outflow from the lake at its north-west end, passing through the city of Zurich, however the outflow is then called the Limmat. The three population and transportation centres are Zurich, Pfäffikon SZ and Rapperswil. Besides Bürkliplatz in Zurich and the Seedamm, there are no bridges across the lake.
