Data The gravity dam was built from 1934 to 1936.[1] It is approximately 38 m[1] above the valley floor and 45 m[1] above the foundation level. The crest of the dam is located at 473.8 m above sea level, is 186.5 m[1] long and 3.50 m[1] wide. The volume of the dam contains approximately 54,400 m³ of concrete.[1] History Planning, Construction Phase, and World War II The plan to build a dam on the Zillierbach stream originated in 1931. When construction began in 1934, cult objects from the turn of the century were excavated. Initially, an arch dam was planned; however, the plan was changed during construction. The building materials were delivered via a feeder railway from Drei Annen Hohne. The aggregates could be mined locally. A dedicated sawmill was built at the dam inlet for the formwork. The cost estimate was 3.31 million Reichsmarks. The main work was completed in June 1936. During excavation work for the dam in 1935, workers unearthed a votive offering[5] from the Bronze Age around 1000 BC below the Peterstein, which is on display in the Harz Museum in Wernigerode. In the final days of World War II (1939–1945), the SS planned to destroy the dam, but the Allies were able to prevent this after a tip-off from the dam master.[1] Source: https://de.wikipedia.org/wiki/Talsperre_Zillierbach

The Zillierbach Dam is located in the Harz/Saxony-Anhalt Nature Park. It stretches between Drei Annen Hohne in the southwest and Nöschenrode in the north-northeast, both of which lie on the Zillierbach stream and belong to the town of Wernigerode, and Elbingerode in the southeast, which, away from the reservoir and stream, belongs to the town of Oberharz am Brocken.
