The dam was put into operation in 1914. Its main purpose is to provide raw water and flood protection for the region and the state capital Dresden. The dam is an Intze gravity dam made of quarrystone masonry with a curved axis. Following damage caused by ageing and as a result of the 2002 flood, the complex was extensively refurbished between 2006 and 2013.
