River

Main is a mapped river in the YearMaps hydrographic index. River courses organise settlement, agriculture and frontier-making more durably than any political boundary, and this reach is indexed against the dams, lakes and cities within its catchment.

About Main

The Main (German pronunciation: [ˈmaɪn] ) is a river in central Germany. It is the longest tributary of the Rhine, one of the major European rivers. It rises as the White Main in the Fichtel Mountains of northeastern Bavaria and flows west for 525 kilometres (326 mi) to meet the Rhine below Rüsselsheim, Hesse. The cities of Mainz and Wiesbaden are close to the confluence.

The largest cities on the Main are Frankfurt am Main, Offenbach am Main and Würzburg. If the Weser-Werra are considered separate, it is the longest river lying entirely in Germany.

Main in Depth

Geography

The Main flows through the north and north-west of the state of Bavaria and then across southern Hesse; against the latter it demarcates a third state, Baden-Württemberg, east and west of Wertheim am Main, the northernmost town of that state.

The upper end of its basin opposes that of the Danube where the watershed is recognised by natural biologists, sea salinity studies (and hydrology science more broadly) as the European Watershed.

The Main begins near Kulmbach in Franconia at the joining of its two headstreams, the Red Main (Roter Main) and the White Main (Weißer Main). The Red Main originates in the Franconian Jura mountain range, 50 km (31 mi) in length, and runs through Creussen and Bayreuth. The White Main originates in the Fichtel Mountains; it is 41 km (25 mi) long.
