Amper

The Amper River, called the Ammer River upstream of Lake Ammer, through which it runs, is the largest tributary of the Isar River in southern Bavaria, Germany. The Ammer and Amper flow in a generally north-eastward direction, reaching the Isar (as the “Amper”) in Moosburg, from the Ammer’s source in the Ammergau Alps, with a flow of 45 m³/s. Major tributaries are: the Glonn, near Augsburg; the Würm, which is the outflow of Lake Starnberg; and the Maisach.The Ammer starts just south of the Passion village of Oberammergau, or Upper Ammer Vale. Cities along the Amper include Fürstenfeldbruck, Dachau and Moosburg.
