The Seewener See ( called Seebnersee in local dialect ) was a lake in the municipality of Seewen in the Swiss canton of Solothurn , which was drained in the late 16th century.

history

The lake was formed about 8000 years ago as a result of a landslide that dammed the Seebach (Seewener Dorfbach) behind it into a lake. In the rainy season the lake reached a length of up to two kilometers and a depth of about ten meters; In dry periods, however, the lake is said to have shrunk rapidly, due to the loose rock through which the water could flow. The establishment of the Seewen settlement, first mentioned in a document in 1147, probably goes back to its proximity to the lake; the name "Seewen" (from Old High German sewin , "near the lakes") also refers to this location.

In the 15th century there were first attempts by the villagers to dig the lake in order to get rid of the large mosquito plagues in summer. In 1589, the master of the road, Konrad Strub von Hauenstein, had a 200-meter-long tunnel built through the rockslide , through which the Seebach could flow completely. The entrance to the tunnel was too high, however, so that the lake silted up into a swamp. It was not until 1917 that a land cooperative was founded in Seewen, which drained the seabed from 1919 to 1923 in order to provide the landowners who owned land in the lake with valuable cultivated land.

In recent times there have been several efforts to revitalize the lake. In 2003, the University of Basel presented a feasibility study according to which the filling of the historical lake area would take less than two months. In the same year, 67 percent of the Seewen population spoke out in favor of revitalization. In 2012 the regional tourism association Schwarzbubenland Tourismus relaunched the project in cooperation with the Forum Regio Plus; The aim is to turn the lake into a nature reserve and local recreation area after it has been re-dammed, and thus make it usable for tourists. The project received support from the Basel Rowing Club , who would like to use the lake for rowing regattas (analogous to the Lucerne Rotsee ), as well as from the geographer and former Seewen mayor Philippe Weber ( FDP ), who rated revitalization as a priority in his community concept "Vision 2015" . The Seewener SP - Cantonal Councilor and farmer Simon Esslinger ( mayor since 2017) expressed himself more skeptically in 2016, who questioned the economic benefits of the project as well as addressing potential ecological problems caused by rising tourist numbers.
