The Schlesiertalsperre , also Weistritz-Talsperre or Breitenhain-Talsperre (Polish Jezioro Bystrzyckie also Jezioro Lubachowskie ), is a dam on the Schweidnitzer Weistritz in the Owl Mountains in the Lower Silesian Voivodeship in Poland. It was built between 1912 and 1917 and has a storage volume of 8 million m³.
It is primarily used for flood protection, at the same time it generates around 4 million kWh of electrical energy from hydropower every year . The barrier structure is a curved gravity dam made of quarry stone masonry according to the Intze principle , which is based on gneiss . According to Kelen in 1933, it cost 2.11 million RM , which corresponds to an inflation-adjusted equivalent of around 9.7 million euros .
The dam is located between Lubachów ( Breitenhain ) and Zagórze Śląskie ( Kynau ), and the Kynsburg is located above the deep valley cut .
