The lake was excavated in 1969 as part of the construction of Autobahn 27 and then converted into a bathing lake as one of four sand extraction points for the construction of the Autobahn. It is fed from groundwater . The water quality is eutrophic to polytrophic .
There is a beach with coarse-grained sand on the north shore of the lake. The bathing area is monitored by a DLRG station. Outside the bathing area, the bank is close to nature and is lined with trees and partly a reed belt. To the west, the lake is separated from the A27 by a narrow strip of wood. A path runs here and the Embser Mühlengraben runs parallel to the motorway . In the east, the border with Lower Saxony runs along the edge of the wooded fringe that largely surrounds the lake.
