Lake Bahrenfeld in the Hamburg district of the same name is a sinkhole lake.
About 260 million years ago (Upper Permian), extensive salt domes were formed over a period of 10 million years by an interplay between the filling of the North German Basin with seawater and subsequent evaporation. In the Hamburg region there are nine salt domes (salt diapirs) of different shape and depth. The thickest salt dome is the Othmarschen Langenfelde Diapir (OLD). It is located in the north-west of Hamburg and stretches from the Elbe for about 20 km in a north-easterly direction to Quickborn. The salt dome is up to 3000 metres deep, in some areas it reaches a few metres below the surface.
Several sinkholes occurred above the Othmarschen Langenfelde Diapir salt dome. Lake Bahrenfeld (size: 5130 m², ground level: NN + 24 m) was formed in this way by a salt cavern near the surface and a subsequent collapse (sinkhole lake).
