The Bergheider See, south of Finsterwalde near Lichterfeld in the county of Elbe-Elster in Germany, is a flooded pit from the former open cast mine of Klettwitz-Nord, northeast of the Lower Lusatian Heath.

The flooding of the pit, under the direction of the LMBV company in charge of dealing with the consequences of lignite mining, began in September 2001 and ended in May 2014.

There are also restricted areas belonging to the LMBV (Lausitzer Mitteldeutsche Bergbau Verwaltungsgesellschaft = Lusatian Central German Mining Administration Company).

Together with the show mine, the lake is being converted into a recreation area with floating houses, a water sports centre and a holiday home park.

[citation needed] The newly renovated Landstraße L 60 from Lichterfeld to Lauchhammer, which runs past the Bergheider See, was closed in summer 2010 but reopened in December 2015.
