Bike Touring Highlight (Segment)
Built from 1963 to 1966, the Innerstetalsperre has no dam, but a dam, which is sealed on the outside with asphalt concrete. At 750 meters, the Innerstetal dam has the longest dam in the Harz and reliably protects against flooding. For water extraction from here from time to time significant amounts are pumped to the waterworks Granetalsperre. In addition, the Innerstetalsperre is a popular destination.

The innermost is a resin flow which was first mentioned as Indrista in 1013. The river is about 95 km long and a tributary of the leash. Its source has the innermost southeast of Clausthal-Zellerfeld, at an altitude of about 615 m above sea level. NN. But before it flows into the Innerstetalsperre below Lautenthal, she has already passed 5 barrages in the Upper Harz water shelf.
The Innerstetalsperre can be reached by turning in towards Langelsheim, away from the B 82. About 2 km from the outskirts, you can reach the dam dam, which was built between 1964 and 1966. The earth dam with its asphalt concrete sealing, with its 750 m is the longest in the Harz. In contrast, the dam with its 32 m height belongs to the dams with the lowest height and also their content of 20 million cbm is relatively small.At full dam you see a huge wreath on the water surface "swim" not far from the dam. It is the upper part of the overflow tower that can carry more than 125 cbm / s of water if required. That's enough to always be safe from flooding, even at high tide. And that is also the main purpose of this dam - flood protection. Because the Innerstetalsperre dams an approximately 95 sq km large drainage area and thereby dams a water surface of 139 ha.Source: ausflugsziele-harz.de/ausflugsziele-sehenswertes/baden/innerstetalsperre.htm
