The Eder Dam was built over 100 years ago to ensure the water supply to the Weser and the Mittelland Canal in the summer months. The villages of Asel, Berich and Bringhausen had to be moved and rebuilt at higher locations. Even today, when the water level of the Edersee is low, you can marvel at the remains of the old villages and hike across the lake bed.
When the 4-arched Aseler Bridge gradually becomes visible again, it is very impressive, also because it is the best-preserved structure. You can even walk over them. It's hard to believe that it's been under water for months and it's somehow fascinating when you stand there and imagine that there would be almost 10 meters of water over you when it was completely full.
