Lerbach, Osterode am Harz

The Söse Dam is a dam in the Lower Saxon part of the Harz mountains near Osterode in the German state of Lower Saxony. It was the first modern dam and reservoir complex (German: Talsperre) to be built in the Harz and was constructed by the Harzwasserwerke between 1928 and 1931. It is used for flood prevention, electricity generation, supplying drinking water and for raising water levels during times of low water. The construction of the dam cost 14.7 million Reichsmarks at the time. The Harzwasserwerke still operate the dam today. In 1933 construction began on a long-distance water pipe from the Söse reservoir, whose northern branch goes as far as Bremen. Today it mainly supplies towns and communities in the Hildesheim and Hanover areas. Since 1980 the town of Göttingen has also been supplied with drinking water from the reservoir.

The Bärenbrucher Teich ("Bärenbruch Pond") is an historic reservoir in the Harz Mountains of central Germany. It lies east of Buntenbock near Clausthal-Zellerfeld. It belongs to the Upper Harz Ponds, that were originally laid out to supply water power for the Upper Harz mines. Its retaining capacity is 186,000 m³ and its barrage is around 7 metres high. The history of the Bärenbrucher Teich goes back to 1634. The water of the Bärenbrucher Teich can be channelled along the Bärenbruch Ditch (Bärenbrucher Wasserlauf), laid in 1948, through a sequence of six water tunnels and intermediate ditches to the Rosenhof, where it was used to supply power to the Rosenhof Pit and, later, the Ottiliae Shaft Power Station. Another drainage outlet is the normal bottom outlet, which discharges water into the Ziegenberger Teich located immediately below it. Today the Bärenbrucher Teich is normally operated as a spillway basin, that is, the bottom outlets are closed and water simply flows over the spillway into the Ziegenberger Teich. There is a Harzer Wandernadel hiking checkpoint (no. 137) in the refuge hut at the eastern end of the dam.
