Feldmoos The surface of the original, undammed Schluchsee, a glacier lake, was around 30 metres lower than that of today's reservoir. Despite the dam, the Schluchsee appears natural. The lake is 7.3 km long by 1.4 km across. Its 63.5 m high dam was built between 1929 and 1932, impounding the river
Schwarza. In order to construct this gravity dam, the natural lake had first to be deepened by 13 metres. That was achieved in 1930 by blasting out a tunnel in the rock. After that the intake structure of the dam could be built. Today the lake has a maximum depth of 61 m. In 1982 the Schluchsee became known Germany-wide as the
Schlucksee ("Swig Lake") because the
German football team 1982 chose the area as their
training camp and some players, permitted by the
team manager,
Jupp Derwall, made full use of it. Excessive
alcohol consumption,
card games and other escapades showed the subsequent world runners-up in a bad light. In 1983 almost all the water in the reservoir was drawn down for inspection purposes, rendering the normal swimming, fishing and sailing activities impossible. This rare occurrence still drew many visitors, however, because for the first time the drowned settlements were visible again. In recent times there have been several conflicts between the Schluchseewerk and the municipality of Schluchsee over the water level of the lake in summer. Whilst the Schluchseewerk is interested in the optimal, economic use of the water and therefore a considerable reduction in the level of the lake, the town is concerned about losing tourists if the lake falls too low for long periods during the summer and exposes a rather unsightly shoreline. == Tourism ==
