I want to know the answer to the following question:
Which river in Thuringia is the most important?
All the background I'm provided with is that "There are no large natural lakes in Thuringia, but it does have some of Germany's biggest dams including the Bleiloch Dam and the Hohenwarte Dam at Saale river same as the Leibis-Lichte Dam and the Goldisthal Pumped Storage Station within the Highland.". Is that enough to answer the question?
