Sternenweiher

The Sternenweiher is a reservoir in the municipality of Richterswil in the canton of Zurich in Switzerland.It lies north-east of Sonntagern and drains into Lake Zurich via the Mülibach. According to the national map, its tributary is called Miesbach.[1]In 1873, the silk manufacturer Rudolf Zinggeler-Syfrig received the rights to use the Mülibach to drive the machines in his Zinggeler AG silk mill. Above Richterswil, the star pond was created by damming the Mülibach. A two-kilometre-long pressure pipe carried the water down to Lake Zurich, where it drove a water turbine in Zinggeler's factory. For amusement and as a symbol of industrialization, from 1875 onwards the manufacturer let the water rise through a nozzle on holidays such as August 1st: A fountain was created with a height of 80 to 85 meters. This fountain was long considered the highest on the continent. In 1972 the power plant was shut down and with it the fountain.[2]The fountain, which was restored by the Richterswil Historical Fountains Association, which was founded in 2003, was put back into operation in 2007. Today it sprays up to 101 m high.
