The Propeller Turbines of the St. Lawrence Power Project

Abstract

Although the St. Lawrence River has long been recognized as a great economical source of water power, its development has been delayed until now for many reasons. The major obstacle has been the 125 miles of river which forms the common boundary between the United States and Canada. In this distance lies the International Rapids section of the St. Lawrence River, which necessitated a joint undertaking by both countries if power was to be developed. The St. Lawrence Power Project is the fulfillment of this joint undertaking. This paper describes the control structure required to harness the river and the design features of the hydraulic turbines which convert the power of this mighty river to useful, dependable electrical energy.
