HISTORICAL NOTE:
The official opening of the Ragged Rapids power development on the Musquash River took place at 2:30 p.m. on Wednesday October 26, 1938 when the generating equipment was placed in operation by the Premier of the Province, the Honorable Mitchell F. Hepburn. Representatives of the various municipalities comprising the Georgian Bay system as well as three members of the Hydro-Electric Power Commission of Ontario were present together with members of the engineering staff responsible for the design, construction and operation of the plant. Prior to the official opening ceremonies about 200 guests of the Georgian Bay Municipal Electric Association and The Hydro-Electric Power Commission of Ontario attended a dinner in the construction department dining room located adjacent to the powerhouse. After the dinner, the entire gathering assembled in the generator room where the opening ceremonies took place. After a brief address, Premier Hepburn operated the governor control mechanism which started No. 2 generating unit, shortly after which this machine was connected to the Georgian Bay system transmission network and placed under load.
