 During most of the 20th century, the area found use as a shooting range, and as a waterlogged marsh where excavated earth and other material was dumped.The range was discontinued in 1978 and shortly thereafter sediments from the nearby Laduviken and other excavated material was disposed within the present catchment area of Spegeldammen, and the lake was created in connection with the housing of the deposits.Today a small pavilion is sitting on the eastern shore of the lake and sheep are grazing the area during summers.
