The Mandelholztalsperre (also: Hochwasserschutzbecken Kalte Bode ) is a flood retention basin and is located between the towns of Elend and Königshütte in the town of Oberharz am Brocken in the Harz Mountains . It dams the Kalte Bode at high tide.
The dam was built between 1952 and 1957 and consists of an earth dam with an integrated inspection corridor made of concrete. In order to protect the dam crest from flooding, an overflow was installed to the south of it as a flood relief. The last time the dam overflowed was during the floods in 1994.
The height of the dam is given inconsistently with 26 m (probably above the valley floor) or 28.4 m (probably above the foundation floor).
At Almondwood an der Wormke (in the rear area of the Almondwood Dam) there are also the remains of an older dam, the Almond Woods Pond , which supplied the Mandelholzer Hütte with water from 1612. The flood disaster of 1855 destroyed the dam and it was never rebuilt.
