The Cranzahl dam is a dam in the Free State of Saxony . It was built in 1949–1952 near Sehmatal - Cranzahl and Bärenstein in the Ore Mountains to supply drinking water to Annaberg-Buchholz and the surrounding area. Along with the Sosa dam, it was one of the two large dam construction projects in the young GDR . In keeping with the zeitgeist of the time, it was given the name "Dam of Friendship".
The dam of the dam is a kinked earth embankment dam with an inclined inner seal made of clay . It is a large dam according to the ICOLD criterion . The dammed waters are the Lampertsbach and Moritzbach.
