It is located in the district Oder-Spree between the town Müllrose in the north and the municipality Mixdorf in the south.

At an elevation of 41,6 m, its depth is maximal 8 m. The lake is the largest water in the Schlaube Valley Nature Park and flown through by the river Schlaube, which runs over a distance of 20 kilometers through the Schlaube-Valley (German: Schlaubetal), a tunnel valley of the last glacial period.

An approximately 9 kilometres long walking path leads around the lake.

The watermill Müllrose at the northern shore was first mentioned in a document in 1275 and is still in use today.
