The Bostalsee is a reservoir in the municipality of Nohfelden in the northern Saarland. It was created in 1979. The dam has a length of 500 metres. The lake is almost exclusively used for recreation. The hydropower from the stored water has been used since the end of 2013 to a small extent to generate electricity, especially to light the circular walk around the lake in winter.[1] The southwestern part of the lake has been designated as a nature reserve.[2]
