The Zillierbach Dam (
The Zillierbach was known as the Holtemme until the 16th century, then from 1558 as the Zilgerbach. Not until much later was it given its present name. Before the construction of the dam at Peterstein, it supplied the mills in Wernigerode and in the area around Halberstadt. Its variable water supply was evened out by an artificial ditch on the south side of the Hohneklippen, the Wormsgraben, built in the late 12th century.
Dam
The barrage is a concrete gravity dam. Initially it was intended to build an arch dam; but this was changed during construction. From 1998 to 2001 the dam was overhauled. In the middle of the wall is the valve house with its operating equipment.
Construction
The plan to build a dam first appeared in 1931. During the early phase of construction in 1934 cult artefacts from around the turn of the eras (AD 0) were found. The construction material was delivered from
Overhaul and modernisation
After 60 years of operation the stability of the dam against collapse could no longer be guaranteed. Likewise the technical equipment was outmoded. From November 1998 to May 2000 the dam and waterworks were overhauled at a financial cost of 7 million
Recreation
Swimming in the reservoir is forbidden in order to protect the fresh water. The reservoir is surrounded by a 4.5-km-long hiking trail. It can be reached from Drei Annen Hohne, Elbingerode or Wernigerode. A footpath leads to the nearby Peterstein mountain summit, from which there is a view over the reservoir. Trees that obscured the view were removed from the mountaintop during dam and reservoir renovation by the forestry commission.
