Salinensee, Salt lake in Bad Dürrheim, Germany.

Salinensee is a lake in Bad Dürrheim divided into the smaller northeastern Kleiner Salinensee and the larger southwestern Großer Salinensee, whose eastern bay connects to the main body by a narrow channel. It covers 3.3 hectares, with a shoreline about 0.5 km long, and is fed by the Stille Musel flowing from northeast to southwest.

The Salinensee was created in 1838 by damming the Stille Musel, which flows through both lake parts from northeast to southwest. It first served the Bad Dürrheim saline, later became a firefighting water reservoir, and from 1928 to 1960 operated as a beach bath. Since 1989 it has also acted as a flood retention basin behind its 6 m high earth dam.

The name recalls the Bad Dürrheim saline works that the lake once supplied. On the northwest shore stands a Seebühne, an open-air stage on the water used for theatre performances, and the lake lies within a popular local recreation area of the spa town.

The lake lies in a recreation area of Bad Dürrheim, with a lake stage on the northwest shore. A 6 m high earth dam holds back the water; up to 60,000 m² can be retained there as flood protection. The Kleiner Salinensee lies northeast, the Große Salinensee southwest, and the Stille Musel flows through both from northeast to southwest.

The lake's 6-metre-high earth dam, built for flood control in 1989, can hold back up to 60,000 m² of water beyond its normal level. The Große Salinensee also has a branching eastern bay linked to the main body only by a narrow channel.
