Lake Lauerz

Lake Lauerz (German: Lauerzersee, old spelling: Lowerzer See) is a lake in the Canton of Schwyz, Switzerland.

Geography

Its water area varies between 310 ha (766.0 acres) and 360 ha (889.6 acres) (depending on water level), a maximum depth of 14 m (45.9 ft), and a water level elevation above sea level of 447 m (1,466.5 ft). [1] [2]

The lake's water area is divided between the municipalities of Lauerz, Schwyz and Steinen. There are two small islands in the lake, Schwanau and Roggenburg, both of which are in the municipality of Lauerz. The villages of Lauerz, on the southern side of the lake and in its eponymous municipality, and Seewen, at the eastern end of the lake in the municipality of Schwyz, lie on or close to the shore of the lake. [2]

The lake's principal inflow is the Steiner Aa, which flows into the north shore of the lake having passed through the village of Steinen, along with a number of smaller streams. The lake's outflow is at Seewen and takes the form of the Seeweren, a 1.5 km (0.93 mi) long stream. The Seeweren in turn flows into the Muota river, some 2 km (1.2 mi) above that river's mouth on Lake Lucerne. [2]

The 1806 Goldau landslide impacted the lake and caused a tsunami 20 metres (65.6 ft) high. This damaged the villages of Lauerz and Seewen and the island of Schwanau, and partly filled the lake. More recently, floods in 1999 and 2005 have affected lakeside properties, especially in Lauerz, and attempts have been made to control the water level by connecting Lake Lauerz through a tunnel to Lake Lucerne.

Lake Zug

Lake Zug is a lake in Central Switzerland, situated between Lake Lucerne and Lake Zurich. It stretches for 14 km between Arth and the Cham-Zug bay. The Lorze as the main feeder river empties its waters into the lake at its northern extremity, but 1 km (0.6 mi) further west issues from the lake to pursue its course towards the Reuss. Due to this poor feeding, Environmental protection is very important as the lake would suffer long term damage if polluted as the second of the rivers, Rigiaa, feeds only a marginal amount into the lake at its southern end. Already a great part of the fauna in the deep parts of the lake has been lost.
