The lake Boisdorfer was created as part of the reclamation of the former open pit Frechen. He got his name in memory of the village Boisdorf, which fell victim to the opencast mine. The lake has a tributary of the small Erft, which compensates for the water loss caused by evaporation and seepage. If the Erft has little water in the summer, the water level of the lake also drops.

The Boisdorfer See is an opencast mining lake, which was created during the recultivation of the former Frechen open-pit mine in a terrain dump. The lake is named after the former Kerpener district Boisdorf, which was dredged in decarburization of the open pit in 1975 and has been located approximately at the site of today's lake.The lake is about 24 m deep, 17 ha in size and has a volume of about 1.5 million m³. The artificial lake is fed by the Kleine Erft; The area around the lake also serves the Erftverband as a flood retention basin for the river.
The lake and its surroundings serve the recreation. It is part of the biotope network with the Kerpener Bruch and the adjoining Marienfeld and is part of the Regio Grün in the Rheinland Nature Park, which was designed as part of the Regional 2010. A circular route around the lake and a wider Kirchweg, which connects the former village centers of the dredged and resettled districts, and the Quirinus hiking trail through Marienfeld are connected to long-distance hiking trails, such as the Erft Cycle Route or the Jacobsweg via Cologne and Aachen.Source: Wikipedia
