What is "zillierbach"

The Zillierbach (until 1558 called the Zilgerbach) is a stream in the Harz mountains of central Germany ( Harz district in the state of Saxony-Anhalt. It is about long. The stream rises on the western side of the Hohneklippen crags and runs initially southwards, then swings northeast at Drei Annen Hohne. South of Drei Annen Hohne it picks up the waters of the Wormsgraben, its main tributary. The Zillierbach supplies the Zillierbach Dam near Elbingerode. In front of the settlement of Voigtstieg it is joined by another two smaller brooks. In the Middle Ages the Zillierbach powered the mills between Voigtstieg and Wernigerode. This section of the valley is still called Mühlental (Mill Valley) today. In its lower reaches before its mouth the stream is known as the Flutrenne. The stream discharges into the Holtemme at Wernigerode northwest of the West Gate (Westerntor). It drops through a vertical height of almost from source to mouth.
