Werbeliner See, Protected lake area in Wiedemar, Germany.

Werbeliner See is a protected area centered on a freshwater lake in northern Leipzig that covers approximately 450 hectares of water. The site includes forests, meadows, and shorelines with varied habitats that visitors can explore on foot or by bicycle.

Lignite extraction at Delitzsch-Southwest began in the mid-1970s after about two years of groundwater lowering, with plans for up to 10 million tonnes a year for Bitterfeld's chemical plants. The villages of Grabschütz, Kattersnaundorf and Werbelin disappeared. Mining ended abruptly around 1990; the residual pit was left to nature, and from 1998 to 2010 it was flooded with water from the Neue Luppe. The area became a nature reserve on 15 May 2019.

The lake serves as a crucial stopover point for migratory birds and attracts birdwatchers seeking to observe diverse species. The protected area functions as a habitat where wildlife has gradually established itself since the mining site was transformed.

The protected area is accessible from several surrounding towns and offers good conditions for walking and cycling around the lake. Visitors should know the terrain is flat and parking is available at main entry points.

In the western part of the reserve, large areas were simply left to themselves after mining ended, with no further engineering works. This preserved a nationwide rare record of conveyor-bridge technology, the so-called Rippenkippen ridges, on a broad scale. Visitors walking the edges can still make out these parallel ridges in the terrain.
