The Innerstetalsperre dam is an earth dam with a multi-layered, external asphalt concrete seal. It has a control gallery along its entire length in the upstream foundation wall. In front of the upstream toe of the dam is a high-water overflow tower, into which the bottom outlet is also integrated. The water from the Innerstetalsperre can be pumped via a 4.6 km long pressure pipeline to the Granetalsperre located to the east, where it can be used for drinking water treatment. Source: Wikipedia
