The Frauensee is a sinkhole lake in Frauensee , a district of the town of Bad Salzungen in the Wartburg district in Thuringia . Originally created without an inflow or outflow, it has been provided with a drainage tunnel since the 18th century, which limits the water level of the lake.
Geography and geology
Naturally, the Frauensee lies in the west of Thuringia in a side valley of the central Werra between the Thuringian Forest and the Rhön . It is surrounded by the place of the same name. The area around Frauensee is a subrosion area with numerous sinkholes.
Since the lowering of the water by the commissioning of an artificial drainage tunnel in the 1770s, the lake has been divided into two bodies of water, which are colloquially referred to as small lake and large lake .
Drainage tunnel
In the 1770s, the steadily rising water level of the Frauensee became a problem for the local situation. It was decided to build an approximately one kilometer long drainage tunnel to drain off the excess water, which flows into the Kieselbach near the Knottenhof . The 0.6 by 1.5 meter gallery was dug against the direction of flow. The work lasted from 1771 to 1778; a worker is said to have drowned when it was pierced. The drainage tunnel leads through natural rock, it was only partially lined, and has seven air shafts. During renovation work in the 1970s, other parts of the tunnel were lined and a new inlet structure was built. In December 2019, the drainage tunnel was placed under monument protection as a cultural monument.
Since the water level of the "small" lake, which absorbed a large part of the local precipitation and, up to the commissioning of the Frauensee sewage treatment plant, also the wastewater, rose continuously due to reduced infiltration into the subsoil, the water and wastewater association Bad Salzungen created an overflow between the small and large lake, so that the lakes are connected again for the first time since 1774.
Tourist use
Around 1900 the idea arose to open up the Frauensee and other sights in the area for tourism. In the course of these efforts, a bathing establishment was created on the lake. Since the lake no longer meets the standards of an official bathing water , the city of Bad Salzungen intended in 2019 to dismantle the facilities (railings and diving tower) that were still in existence from the GDR era. This means that you can no longer bathe officially in the lake, but only at your own risk.
