LOCATION OF MAIN RIVER
The Main is a river in Germany,329 miles long, and it is one of the more significant tributaries of the Rhine.
The Main flows through the German states of Bavaria, Baden-Württemberg and Hesse. Its watershed competes with the Danube for water; as a result, many of its boundaries are identical with those of the European Watershed. The Main begins near Kulmbach at the joining of its two headstreams, the Red Main and the White Main. The Red Main rises in the Frankish Alb, 30 miles in length, and runs through Creussen and Bayreuth. The White Main rises in the mountains of the Fichtelgebirge; it is 25 miles long. Major tributaries of the Main are the Regnitz, the Fränkische Saale, the Tauber, and the Nidda.
The Main is navigable for shipping from its mouth at the Rhine close to Mainz for to Bamberg. Since 1992, the Main has been connected to the Danube via tha Rhine-Main-Danube Canal and the highly regulated Altmühl river. The river has been canalized with 34 large locksto allow vessels to navigate the total length of the river.
