This dive site, Haselbacher See, is a fascinating flooded former open-cast lignite mine located on the state border of Saxony and Thuringia in Germany. Its unique history as a mining site now submerged offers a distinct underwater landscape for divers to explore, with potential remnants of the mining operation forming interesting contours. The water sovereignty on the Saxonian territory is managed by the DAV - Saxony as a tenant, ensuring organized access for divers. The Thuringian side is also utilized for various water sports and tourism.
Since its flooding, the Haselbacher See has developed a rich and diverse underwater ecosystem. Divers can expect to encounter a variety of freshwater flora, creating lush underwater gardens. The fauna is particularly well-represented by fish species such as carp, perch, and roach, which are common and provide ample opportunities for observation and photography.
The best time to visit for diving would typically be during the warmer months, from late spring to early autumn, when water temperatures are more comfortable. Given its shallow maximum depth of 8 meters and average depth of 4 meters, it is an excellent site for beginner divers, training, and those interested in freshwater macro photography or unique underwater landscapes. Divers should be mindful of potential boat traffic on the Thuringian side and prepare for cooler water temperatures, especially outside of peak summer.
