Editing Geography of Württemberg (section)

==Hydrography==

About 70% of Württemberg belongs to the basin of the [[Rhine]], and about 30% to that of the [[Danube]]. The main river, the [[Neckar]], flows northward for {{convert|186|mi|km}} through the area to join the Rhine, draining with its tributaries (notably the rivers Rems, Kocher and Jagst) 57% of the former state of Württemberg. The Danube flows from east to west across southern Württemberg, a distance of {{convert|65|mi|km}}, a small section of which crosses through former [[Hohenzollern]] territory. Just above [[Ulm]] the river [[Iller]], which forms the boundary between Bavaria and Württemberg for about {{convert|35|mi|km}}, joins the Danube. The [[Tauber]] in the north-east joins the [[Main (river)|Main]]; the Argen and Schussen in the south flow into Lake Constance.{{sfn|Chisholm|1911|p=856}}

The lakes of Württemberg, except those in the [[Black Forest]], all lie south of the Danube. The largest is the [[Federsee]] (2.6&nbsp;km<sup>2</sup>), near [[Bad Buchau]]. About one-fifth of [[Lake Constance]] forms Württemberg territory.{{sfn|Chisholm|1911|p=856}}

[[Mineral spring]]s abound; most famously at the spa of [[Wildbad]], in the Black Forest.{{sfn|Chisholm|1911|p=856}}
