Untersee, Mittelsee and Obersee Ville is a chain of three lakes separated only by narrow dams in the large forest-lake landscape of the Ville. They belong to the follow-on landscape of the early lignite mining from the end of the 19th to the middle of the 20th century, which still dominates the entire area today. Thus, the surrounding, forest-used deciduous and deciduous forests on reclaimed ground, recognizable by the many types of woody, including many natives, but also pines, Robinia and red oak in a few ages. The lakes represent residual holes that have filled up with the re-emergence of groundwater with water and are largely left to their further development. Since the forest recultivation from 1925 they are surrounded by forest, which reduces the nutrient input from the outside, which is very beneficial to biodiversity.
NRW-wide, but largely hidden to the visitor, the lawns are made of candlestick algae (so-called Characeenrasen), which contains of the three mesotrophic waters, especially the submarine. Easier to see is the variety of riparian and aquatic plants with large reeds and extensive floating leaf stocks of spawning herbs, pond and water lilies. They attract a variety of rare dragonflies, leading to the outstanding biodiversity of up to 32 species.
