Lake Dreiweberner See has a water surface of 2.86 square kilometres. The Weißkollm lakeside bathing area is located on the northern shore of Lake Dreiweiberner See and is about 280 metres long. Parking, a beach bar selling snacks and drinks, bathroom facilities and a beach volleyball field are all close to the bathing area. Directly behind it is a caravan park. Further along there is an asphalted 8 kilometre-long lake circuit.
Lake Dreiweiberner See was created by flooding the former Dreiweibern surface lignite mine.
