Wendebach Reservoir (German: Wendebachstausee) is an artificial lake with a surrounding recreation park (Erholungspark Wendebach) in the municipalities of Gleichen and Friedland, Lower Saxony, Germany, about 8 km south of Göttingen.

It is a popular summer outing goal for residents and students of Göttingen.

In addition, there are some park facilities such as a first-aid post,[1] grills, a food stall and outhouses.

In the summer of 2010, the Ministry for the Environment announced that the reservoir does not provide flood protection and that the dam is unstable and must be removed.

[4][5] Nevertheless, after political pressure, the situation was re-evaluated, and a removal of the top part of the dam has been declared adequate when combined with some re-building.
