Built from 1979 to 1982, the dam regulates the water table and ensures the supply of drinking water to the Mulhouse conurbation and its surroundings. It is a protected place, classified as an approved voluntary nature reserve. The Mulhouse water service and the joint syndicate of the Michelbach dam ensure the management and operation of the infrastructures. A 4km pedestrian circuit (about 1h30 walk) allows, thanks to educational panels, to discover and observe many species of birds that nest there or are passing through (cormorant, osprey, crow, etc.). On the horizon stand out the peaks of the Vosges such as the Rossberg, the Thannerhubel, the Markstein or the Grand Ballon. Guided tours are organized in summer by the Tourist Office of Thann-Cernay.
