The Edersee

After visiting the town of Bad Wildungen, we went onto the Edersee which was only 3 kms away. It was a lovely day and we were kept busy by walking along the dam wall, going into the museum, going for a boat ride and the kids playing at the Aqua centre.
The next time we go, will be in summer when the kids can swim and I would also like to go up to the Waldeck Castle and have a closer inspection. Apparently, there is a cable car up to the Castle.
Here is some info that I got off Wikipedia about the Edersee.
The Edersee is a large reservoir created by the construction, from 1908 to 1914, of a rock and concrete dam across the Eder river, near the small town of Waldeck, to generate hydropower and regulate water levels for shipping on the Weser river. It lies at the northern edge of the Kellerwald.
The dam was destroyed by special bouncing bombs dropped by British Lancaster bombers during the night of May 16/17, 1943, creating massive destruction and loss of life downstream, including the drowning death of 749 Ukrainian POWs in a labor camp just below the dam. Through the breach in the dam, 70 meters wide and 22 meters deep, some 8,000 m³ of water per second emptied in 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.
The dam was rebuilt within months by forced labor, and the lake today is a major summertime recreational facility. It's capacity of 199.3 million m³ makes it the third largest reservoir in Germany.
At low water, in late summers of dry years, the remnants of three villages (Asel, Bringhausen, and Berich), along with a bridge across the original river bed, that were submerged when the lake was filled in 1914, can be seen, and descendants of people buried in the now submerged cemeteries go to visit the graves of their ancestors.
The 1954 film, The Dam Busters chronicled the British attack on the dam
