The paper relates the experience of a large hydroelectric development on an erratic river, in endeavoring to accomplish most effective combined steam and hydroelectric operation, indicating that a river may be developed to an extent many times its low water flow where there is extended cooperation between customer and power company in determining, by experimenting, the economy of further supply of hydroelectric power. A plea is made for drawing up power contracts in a fashion to encourage effective combined operation of hydroelectric plant with customer's existing steam equipment.
