Ragged Rapids

The first municipally owned hydroelectric power plant for the long-distance transmission of electricity in North America was built by the Orillia Water Light and Power Commission in 1901 on the Severn River at a natural constriction in the river at Ragged Rapids.  The emerging community became known as Hydro Glen when a post office was established in 1912.

The Orillia Water Light and Power Commission was persuaded by the offer of financing from the Dominion Government and the provision for future increased supplies of electricity. As a result of this agreement, the construction of the new dam and powerhouse at Swift Rapids began in 1913, and was briefly interrupted by the outbreak of the war in 1914. The Ragged Rapids Power Plant was demolished in 1917.
