Saar (river)

The Saar (/sɑːr/, also US: /zɑːr/, German: [zaːɐ̯] (listen); French: Sarre [saʁ]) is a river in northeastern France and western Germany, and a right tributary of the Moselle. It rises in the Vosges mountains on the border of Alsace and Lorraine and flows northwards into the Moselle near Trier. It has two headstreams (the Sarre Rouge and Sarre Blanche, which join in Lorquin), that both start near Mont Donon, the highest peak of the northern Vosges. After 246 kilometres (153 mi) (129 kilometres in France and on the French-German border,[1] and 117 kilometres in Germany) the Saar flows into the Moselle at Konz (Rhineland-Palatinate) between Trier and the Luxembourg border. It has a catchment area of 7,431 square kilometres (2,869 sq mi).

The Saar flows through the following departments of France, states of Germany and towns:

On the banks of the Saar is the UNESCO-World Heritage Site Völklinger Hütte. At Mettlach the Saar passes the well-known Saar loop. The lower Saar in Rhineland-Palatinate is a winegrowing region of some importance, producing mostly Riesling. Until the early 20th century, much more wine was grown on the banks of the Saar, reaching much further up from the mouth of the river, up to Saarbrücken. Only in the early 21st century have some enterprising farmers from the Saarland area started experimenting with winegrowing again.

The name Saar stems from the Celtic word sara (streaming water), and the Roman name of the river, saravus.

  • Length: 246 kilometres (153 mi), (129 kilometres in France and on the French-German border, 117 kilometres in Germany)
  • Catchment area: 7,431 square kilometres (2,869 sq mi)

The Saar was very important for the Saarland coal, iron and steel industries. Raw materials and finished products were shipped on it by water via the Canal des houillères de la Sarre, the Marne-Rhine Canal and the Rhine, for instance, to the Ruhr area or the port of Rotterdam.

The lowermost 87.2 km (54.2 mi) section from the confluence of Saar and Moselle at Konz up to the city of Saarbrücken have been upgraded for navigation with Class Vb ships. The 17.5 km (10.9 mi) section between Saarbrücken and Sarreguemines is navigable for smaller Class I ships.[2] At Sarreguemines the 64 km (40 mi) Canal de la Sarre (also navigable for Class I ships) connects the Saar with the Marne–Rhine Canal at Gondrexange.[3]
