The lake was created by flooding the former Niemtsch open-cast mine between 1967 and 1973.
It is the centerpiece of the Lusatian Lake District, which is transforming former mining pits into a major European water sports landscape.
The lakebed depth reaches up to 40 meters in certain sections.
A dedicated 'floating house' development exists on the water, highlighting the area's modern architectural reuse of mining land.
The lake has been designated a landscape conservation area since 1975.
Senftenberg Lake is a 1,300-hectare flooded former open-cast lignite mine located in the Lausitzer Seenland region of Germany. It is one of the largest artificial lakes in the country, created through the recultivation of the former Niemtsch mine. The site features a 18-kilometer long perimeter path designed specifically for cycling, skating, and hiking. The lake includes several sandy beaches, with the Senftenberg and Niemtsch districts serving as primary recreational hubs. Water quality is strictly monitored and consistently categorized as high-grade for swimming. A marina provides docking facilities for small watercraft, while the surrounding area is part of a larger interconnected network of navigable waterways. The lake serves as a significant hub for windsurfing, sailing, and stand-up paddleboarding due to its open landscape. The shoreline transitions from sandy beaches to forested sections and reed belts protected for local bird populations.
