Stausee Losheim, reservoir in Germany

Stausee Losheim is a reservoir in the Saarland region near Losheim am See, featuring a large water surface surrounded by expansive green areas along the shoreline. The body of water stretches across a natural landscape with forest areas and has accessible waterfront sections, including a beach area with lounging spaces and water sport facilities.

Planning for the lake began in 1969 with backing from the Saarland council and federal funds for tourism facilities. Minister-President Franz-Josef Röder cut the first turf on 26 September 1972, and the lake opened on 28 April 1974 after 19 months of construction and impounding. It was created as a leisure and bathing lake fed by the Losheimer Bach, dammed by an earth embankment.

The reservoir takes its name from the nearby town of Losheim am See and serves as a meeting place where locals and visitors from the region gather. The beach area and waterfront are spots where people swim, have picnics, and spend time together, making this water body an important part of community life.

A 4.1-kilometre circular hiking trail runs around the lake, past a boat harbour, minigolf course, restaurants and the beach bath. The water is also used by diving clubs. The site lies at 330 metres above sea level within the Saar-Hunsrück Nature Park, near Losheim am See and Merzig.

The lake is used as a diving site by several diving clubs, which train in its water. The reservoir is fed by the Losheimer Bach, a 20.66 km tributary of the Prims with a catchment of 110.9 km². It lies at 330 m above sea level within the Saar-Hunsrück Nature Park.
