Tachensee

The Tachensee is a lake in the district of Weilimdorf in the state capital Stuttgart of Baden-Württemberg and the only natural lake within the city limits.

The Tachensee is located on the western edge of the Greutterwald nature reserve at the foot of the Lemberg ridge between Weilimdorf and Korntal at an altitude of 311.4 m above sea level. From a natural landscape perspective, the lake and its surroundings belong to the sub-region of the southern Strohgäu edge of the Neckar basin. The underlying rock is the clay-rich gypsum keuper, through which a fault line runs from east to west, passing right through the lake. The natural drainage leads approximately along its course westward over the adjacent area of Reisachmulde, part of the Reisachmulde-Lemberg landscape protection area, to the Weilimdorfer Lindenbach, a tributary of the Glems, which drains into the Neckar via the Enz. Less than half a kilometer east of the lake runs its watershed to the catchment area of the Feuerbach, a left tributary of the Neckar above the much larger Enz.
