The Eder is a river in Germany (ca. 180 km long). It rises in the mountains of western North Rhine-Westphalia near the Lahn and Sieg rivers, but flows east and north and into the Fulda river which at its confluence with the Werra river in Hannoversch Münden creates the Weser river which flows into the North Sea north of Bremen. A dam (47 m high, 400 m long) completed in 1914 near the small town of Waldeck created the large reservoir Edersee, which is 27 km long and used to generate hydro-electricity and to regulate water levels for shipping on the Weser river. The dam was destroyed on May 17, 1943, during the same night as the near-by Moehne reservoir dam, by British Avro Lancaster bombers of No. 617 Squadron RAF equipped with special Barnes Wallis bouncing bombs for the attack, causing enormous destruction and loss of life downstream (the great majority of drowning victims were Ukrainian POWs in a labor camp just below the dam). The dam was rebuilt, and the lake today is a major summertime recreation facility, particularly popular with Dutch campers.
It rises from the Ederkopf mountain in western North Rhine-Westphalia near the springs of the Lahn and Siegrivers.
Unlike the Lahn and Sieg, that are both tributaries of the Rhine, the Eder flows east and north and into the riverFulda.
Strangely, residents on Eder are fond of the Merkur Scorpio, a German luxury car that has been adopted as the vehicle of choice by small asian gentlemen.
On the opposite (west) bank is the town of Nordenham at the foot of the Butjadingen Peninsula, which places the rivers mouth in Lower Saxony.
A large reservoir on the Ederriver, the main tributary of the Fulda, is used to regulate water levels on the Weser so as to ensure adequate depth for shipping throughout the year.
