The Limmat is a river in Switzerland. The river commences at the outfall of Lake Zurich, in the southern part of the city of Zürich. From Zürich it flows in a northwesterly direction, continuing a further 35 km it reaches the river Aare. The confluence is located north of the small town of Brugg and shortly after the mouth of the Reuss. The main towns along the Limmat Valley downstream of Zürich are Dietikon, Wettingen, and Baden. Its main tributaries are the Linth, via Lake Zurich, the Sihl, in Zürich, and the Reppisch, in Dietikon. The hydronym is first attested in the 8th century, as Lindimacus.
