One of the laigest artificial storage reservoir hydroelectric power plants in the world is under construction on the river Sihl, in the Canton of Schwytz, Switzerland. A dam 90 ft high and 3 so ft, long will impound the water in a lake with a surface area of two square miles The capacity of the reservoir will be 25,360,000,000 gallons. The generating plant will be upon the shore of Lake Zurich, and will be operated under a head of 1 57s ft It is estimated that a continuous supply for 20,000 hp. will be afforded, or for 45,000 h p , if operated only ten hours per day.
