This reservoir is situated a few kilometers away from Bad Harzburg. Its primary purpose is to…read moreprovide drinking water to the region, but it also produces electricity. The walk there is pleasant despite its name (Teufelsstieg - devil's climb). When we were there in August, the water level was quite low. You can taste the water from a little fountain situated on the Western side of the dam. The dam has a nice bit of history because the demarcation line between West and East Germany went right across it. Workers were originally only allowed to stay on their side of the dam which must have made for some weird interactions. The river is called the Ecker and ultimately flows in the Weser in direction of Bremen. The lake is called Eckerstausee and the dam Eckertalsperre. It was all a little bit confusing to us non-native speakers :)
