The Lusatian Lake District[1][2][3] (German: Lausitzer Seenland, Lower Sorbian: Łužyska jazorina, Upper Sorbian: Łužiska jězorina) is a chain of artificial lakes under construction in Germany across the north-eastern part of Saxony and the southern part of Brandenburg. Through flooding as a part of an extensive regeneration programme, several decommissioned lignite opencast mines are in the process of being transformed into Europe's largest artificial lake district. However, the requirements of the project, especially the necessary water resources, are controversial.
