The artificial lake was created in the 1950s-1960s by flooding a sandpit.
The lake was formed by flooding of a former gravel quarry by the seepage of river water. There are three islands on the lake and two spurs of land towards the lake. At the northern end, the lake is connected to the Elbe River by a flow about 300 metres long. It has an area of about 90 hectares and is a popular recreational spot with sandy shores.
It can be found between the villages of Velké Žernoseky, Píšt'any and Žalhostice in the Litoměřice district.
