Ammer (Neckar)


The is a small river in Baden-Württemberg, Germany, a tributary of the Neckar.
It has its source southwest of Herrenberg. Along the southern edge of the Schönbuch, it flows through Herrenberg, Ammerbuch, Unterjesingen and Tübingen, before it discharges into the Neckar at Tübingen-Lustnau after.

Geography

Course

Origin of the Ammer are Ammer springs in the upper valley five spring pots southwest of Herrenberg in the district of Böblingen. From there the Ammer flows through the valley named after it at the southern edge of the Schönbuch nature park as well as the communities Gültstein and Ammerbuch, uniting in Tübingen with the Goldersbach and flows a little later in the Tübingen district Lustnau from the left into the upper Neckar. On its way of 22,5 km the Ammer falls about 94 meters.
The Ammer river crosses the villages Gültstein, Altingen, Reusten, Poltringen, Pfäffingen, Unterjesingen, the hamlet Ammern and Tübingen.

Hydrological spring branch

Just 260 m after the Ammer leaves its main spring, the year-round Aischbach flows to it from the left, which has already flowed for more than four kilometres and usually carries more water than the Ammer. Hydrologically speaking, it is therefore the main source arm of the Ammer.
The Aischbach is water-bearing all year round from the time it passes under the dam of the Gäubahn near Herrenberg railway station. Above the railway embankment the water flow is unstable. Several ditches converge there, draining in particular the northern and western area around Herrenberg and still beginning in the community areas of Jettingen and Mötzingen in the west. Their stream valleys were formed very early in geological history; today, however, these ditches only carry water temporarily after heavy rainfall.

Ammer Channel

Since 1493 the Ammer Canal branches off to the right at the Ammerhof, at here called Neue Ammer, which at first flows parallel to the river towards Tübingen. While the Ammer itself only touches the medieval city limits of Tübingen on its northern side, the Ammer Canal, also popularly called Stadtammer, flows through the Old Town, before it divides again at the Nonnenhaus and flows in two underground canals, one on the southern edge of the Old Botanical Garden back into the Ammer, the other under Mühlstraße into the Neckar. The Ammer canal was formerly used to drive various mills and for the copper hammer.
