Eder Dam

In Call of Duty
The dam is rebuilt and the player, a British Special Forces agent, must sabotage AA guns on the dam during the summer of 1943, when in fact the mission is happening on Sept. 2nd, 1944 a year after the actual date of "Operation Chastise".

In World War II
The dam was a part of Operation Chastise, it was destroyed by special bouncing bombs dropped by British Lancaster bombers of No. 617 Squadron RAF in the early morning of May 17, 1943, creating massive destruction and loss of life downstream. Through the breach in the dam, 70 meters wide and 22 meters deep, water emptied at the rate of 8,000 m³ per second into the narrow valley below, a total of about 160 million m³. A flood wave of 6-8 meters in height roared through the river valley as far as 30 km downstream, before it diminished in the widening floodplains of the lower Eder, the Fulda and the Weser. About 70 people perished[1] (some non-German sources erroneously cite[2] an early total of 749 for all foreigners perished in all POW and labour camps downriver of the Möhne dam as the casualty at supposed POW or labour camp just below the Eder Dam.)

Trivia
The mission to sabotage Eder Dam in the game Call of Duty is set one year after the actual date of "Operation Chastise".

Did you know that, even though the Germans repaired the dams quickly, the impact of the raid on German industry in the Ruhr valley and indeed on the civil population was significant? In the Möhne and Ruhr valleys 11 factories were totally destroyed, 114 seriously damaged, 25 road and rail bridges were destroyed and throughout the region power, water and gas supplies were seriously disrupted. The breaching of the Eder dam caused severe disruption to road and canal communications and destroyed over 50 hectares of valuable agricultural land. In the flooding below the Möhne there were 1,294 casualties including 593 foreign workers. The flooding below the Eder resulted in a further 47 deaths. For the remainder of the War the Germans had to divert an additional 10,000 troops to guard the Dams.
