The Ruhr
is a river in western Germany
(North Rhine-Westphalia), a right tributary (east-side) of the Rhine. Description and history[edit]

The Ruhr
valley near Bochum
during a flood

The source of the Ruhr
is near the town of Winterberg
in the mountainous Sauerland
region, at an elevation of approximately 2,200 feet (670 m). It flows into the lower Rhine
at an elevation of only 56 feet (17 m) in the municipal area of Duisburg. Its total length is 219 km (136 mi), its average discharge is 79 m³/s (cubic metres per second) at Mülheim
near its mouth. Thus, its discharge is, for example, comparable to that of the river Ems in Northern Germany or the River
Thames in the United Kingdom. The Ruhr
first passes the towns of Meschede, Arnsberg, Wickede, Fröndenberg, Holzwickede, Iserlohn
and Schwerte. Then the river marks the southern limit of the Ruhr
area, passing Hagen, Dortmund, Herdecke, Wetter, Witten, Bochum, Hattingen, Essen, Mülheim
and Duisburg. The Ruhr area
Ruhr area
was Germany's primary industrial area during the early- to mid-20th century. Most factories were located there. The occupation of the Ruhr
from 1923-24 by French forces, due to the Weimar Republic's failure to continue paying reparations from World War I, provoked passive resistance, which saw production in the factories grind to a halt. As a result, the German hyperinflation crisis grew even worse. During World War II, two of the dams on the Ruhr, the Möhne Dam
Möhne Dam
and the Sorpe Dam
Sorpe Dam
were targets for Operation Chastise, in which special "bouncing bombs" were developed to take out the dams and flood the valley, with the hope of seriously affecting the German industries there. The story was told in a 1951 book and the popular 1955 film made from it, The Dam Busters.

The drainage basin of the Ruhr

Lakes[edit] There are five Ruhr
reservoirs on the river, often used for leisure activities.
