Clausthal-Zellerfeld has a rich history as a mining city. The Harz produced a variety of metals, including silver and lead. And because the underground mines needed a lot of water to drive it’s lifts and other machinery, the miners built a lot of artificial lakes. Sometimes even multiple of them in a row. And since the water needed to go somewhere, after it was being put to good use, they dug tunnels to lead it away from the mines. 

Due to that, and due to the fact that there where a lot of mining operations in the Upper Harz Area, there where over 250 lakes built between the 16th to 18th centuries. 


Some of those lakes are used to provide fresh drinking water to the area, while some are used for recreational purposes only. Read more about the so called Oberharzer Wasseregal (Upper Harz Water Regale) here
