It is part of the Diemeltalsperre hydropower system (DiT)[3] comprising the Diemel Dam, the equalizing basin, the power plant and the reservoir itself, owned by the Federal Waterway and Navigation Authority and managed by its Hann.

LocationEdit

The Diemelsee is located a few kilometres northeast of the Upland in the northeastern foothills of the Rothaar Mountains that lie in the northeast of the Rhenish Massif. It lies mainly within the county of Waldeck-Frankenberg, its smaller northern section and its dam belonog to the county of Hochsauerlandkreis. In is also within the Diemelsee Nature Park between Willingen and Marsberg on the territory of Diemelsee and the borough of Marsberg on the River Diemel and its tributary, the Itter. Its dam stands about 500 metres south of the village of Helminghausen (southwest of Marsberg). The only shoreline village is Heringhausen.

The Diemelsee lies in a forested Central Upland countryside, whose highest point in the vicinity of the reservoir is the Köpfchen (ca. 610 m above sea level (NHN); west of the Itterarm in the west). Immediately east-southeast of the dam rises the Eisenberg (594.6 m) and a few kilometres to the south of the dam is the mountain of Koppen (715.1 m).
