The Sihlsee (in English sometimes called Lake Sihl) is an artificial lake in the Swiss canton of Schwyz, near the town of Einsiedeln. The lake was created by damming the river Sihl and flooding a section of the upper Sihl Valley.The lake feeds the Etzelwerk power station, which is located 5 kilometres (3 mi) to the north-east in Altendorf on the upper section of Lake Zürich (the Obersee) and which supplies electricity to the Swiss Federal Railways (SBB). Its concrete dam is 33 metres (108 ft) high and 124 metres (407 ft) m long. The lake is the largest artificial lake of Switzerland in terms of surface with a maximum length of 8.5 kilometres (5 mi) and maximum width of 2.5 kilometres (2 mi). The maximum depth is 17 metres (56 ft), and the lake has an approximate volume of 96,000,000 m3 (3.4×109 cu ft).The power plant project started in 1932. A concrete dam and two viaducts over the lake were built before 1937 when the valley was flooded. As a result 107 farms disappeared completely and 1762 persons had to leave their homes.A failure of the dam could lead, according to studies, to an 8-metre (26 ft) high flood wave through the lower Sihl Valley reaching the Altstadt of the city of Zürich, the biggest city in Switzerland, within 2 hours. This threat has led the City of Zürich to develop, publish and test evacuation plans for the affected areas of the city, and especially the area around Zürich Hauptbahnhof railway station.

Outer Schwyz
Outer Schwyz

Outer Schwyz (German: Ausserschwyz, formally Kanton Schwyz äusseres Land, Canton of Schwyz Outer Territory) was a half-canton of Switzerland from 1831 to 1833. In 1831 the three outer districts of Schwyz, centered on Pfäffikon, March and Einsiedeln, and the district of Küssnacht, wished to secede from Schwyz within the scope of the regeneration movement. They were mainly concerned by their political disadvantage in comparison to the more ancient part of the canton and the unwillingness of conservative elements to reform the canton's constitution.The remaining half-canton was called Inner Schwyz; it comprised the older part of the canton as well as the community of Wollerau. In January 1831 a provisional government of the half-canton was instituted at a people's assembly at Lachen. After further negotiations, the constitution was then agreed in April 1832. The half-canton was provisionally recognised by the Confederal government in April 1833, and Joachim Schmid was recognised as the official delegate to the federal parliament. In July 1833, [Inner] Schwyz invaded and occupied the district of Küssnacht under Colonel Theodor Ab-Yberg. The Confederal government then intervened militarily and forced the parties to unite. In October 1833, following negotiations, a new constitution was introduced, which provided for equal political rights throughout the whole canton.The capital of Outer Schwyz alternated between Lachen and Einsiedeln.
