Eder Dam

Eder Dam

Like the Mohne, the Eder dam was a Gravity dam made from granite masonry blocks built between 1908 and 1914. It is located 60 miles south east of the Mohne. At 145 feet (44 meters) high it was 25 feet higher than the Mohne but at 430 yards (393 meters) in length it was not as long. The base was 119 feet (36.2 meters) thick and 20 feet (6 meters) thick at the top. The Eder dam held back 200 million tons of water - the largest reservoir in Germany.

Due to its location surrounded by large hills, the Germans believed the Eder dam would be almost impossible to attack and therefore it had little defence unlike the Mohne. There were no anti-torpedo nets or anti aircraft guns. There were only two guards on patrol on the dam with rifles.
