The Großer Mittelberg (the short form Mittelberg is also common) is a ridge in the Harz Mountains of Germany that begins immediately northeast of Lonau in the district of Göttingen in Lower Saxony. It separates the valley of Kirchtal, through which the Große Lonau flows, from the Mariental and the Kleine Lonau. is Although it is the nearest subpeak to the village of Lonau, the Großer Mittelberg is, at 531 metres, not the highest point, but may be viewed as a main summit due to its prominent location. From here on, the ridge only climbs gently in a northeasterly direction and has several more subpeaks with small wind gaps. To the north the Großer Mittelberg transitions to the ridge of Auf dem Acker without any noticeable wind gap. The Großer Mittelberg is almost entirely covered in beech woods and lies within the Harz National Park.

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.
