Spremberg Dam (German: Talsperre Spremberg) and its associated reservoir (Spremberger Stausee) lie between Cottbus and Spremberg and impound the River Spree. Together with the surrounding countryside they make up the protected landscape also known as the Talsperre Spremberg. The dam itself is made of earth and is the only one in the state of Brandenburg that counts as a "large dam". Its purposes are industrial water supply, flood protection, electricity generation, drought protection and recreation.
