Limmat

The Limmat is a river in Switzerland which starts in the town of Zurich at the north end of Lake Zurich and flows in northwestern direction until it flows after 35 km into the river [Aar]e north of the small town of Brugg[?] and shortly after the mouth of the Reuss.

It's name comes from Linth and Maag the main tributaries of the lake of Zurich before the Linth river control.

It's main tributaries are the Sihl (in Zurich) and the Reppisch (in Dietikon).

The major towns on the Limmat beside Zurich are the much smaller Dietikon, Wettingen, and Baden with smaller villages in-between.

Like many Swiss rivers, it is intensively used for production of hydroelectric power: along its course of 35 km, its fall is used by no less than ten hydroelectric power stations.
