Dive-site story
Formed from a former open-cast lignite mine near Eschweiler, Blausteinsee is a key freshwater training lake for the Aachen region. Divers explore clay drop-offs, sunken boat hulls, art objects, and several anchored platforms. Shallow vegetated zones line the perimeter, while the central basin drops into dark, cold depths.
Submerged training platforms and intentional boat wrecks
Littoral reed and weed beds hosting hunting freshwater fish
Deep clay slopes and silt plains across the basin floor

Seasonality
