Upper Harz rivers and reservoirs (Innerste, Söse, Grane, Eschenbach pond)
Lower Saxony, Upper Harz (Bad Grund, Lautenthal, Clausthal), Germany
Rivers and surface water
- Type
- River or surface water
Former Pb-Zn, fluorite and barite district of the Upper Harz: the flooded shafts of Bad Grund (Achenbach), Clausthal (Knesebeck) and Lautenthal (Lautenthals Glück) drain into the 32 km long Ernst-August drainage adit, which also receives surface water from mining ponds and ditches and discharges into the Markau at Gittelde. Sampled in February and June 2024 and September 2025 (Kaufmann et al., 2026, preprint). Low dissolved Sb (0.03 to 1.15 µg/L): waters close to the geochemical background. Coordinates not published. Surface waters outside the adit: Innerste River and its reservoir (Innerstetalsperre), Grane reservoir near Astfeld (Granestausee), Söse and lower Eschenbach pond (mining water system).
