Lakes in Horlitzer Berg are primarily characterized by their origin as former mining areas within the Muskau Arch. These bodies of water, often referred to as opencast mining lakes or residual holes, have transformed into natural landscapes. The region's unique geology, shaped by past lignite and clay mining, has created a distinctive environment for these lakes. Visitors can explore areas where former pits have filled with groundwater, leading to the formation of new aquatic ecosystems.

Sölle are landforms that were created during the Ice Age. In Low German, Soll means something like water hole. When the inland ice melts at the end of the cold period, so-called dead ice blocks can be buried in the ground. Over time they melt and small lakes form. They gradually silt up and what remains are shallow depressions with vegetation in moist locations. The target in Groß Kölzig is only filled with water after heavy rainfall.
