sunday drive: talsperre lütsche (10. 941)

On the way back from some window-shopping, we took a detour through the Geratal to Frankenhain for a stroll around the second biggest artificial lake in the region (previously). Dammed in 1935 by the Deutschen Reichsbahn in order to provide a source of water for stations in Erfurt and Arnstadt, by the time the reservoir (Stausee) was completed steam-powered locomotion was being superseded and it was converted to hydropower—and today the same supply-system to cool data centres in Neudietendorf and for brewery operations connected to the train stations that have repurposed the cisterns. The tributary rivers have their source near the winter sports destination Oberhof, whose ancient volcanic composition of quartz porphyry were also the quarry for the retaining walls. Used primarily for recreational activities currently, it was certainly a nice walk down to the beach and good to visit the area again.
