摘要

The Ministry of Natural Resources owns and operates over 300 dams in Ontario. Many of those structures were constructed by the logging industry and no longer serve a useful function for flood control. The date, however, none have been decommissioned. The Finlayson and Distress dams are located on the Big East River just west of the Algonquin Park border. Both were originally constructed in the 1930s to serve the interests of the logging industry. Throughout the years, concrete in both structures has deteriorated and, if they were to remain in service, the dams would need major repairs. Engineering studies showed that the complete or partial removal would have no effect on either flood control or low flow augmentation. On this basis, studies were advanced leading to the decision to decommission both dams. This paper describes processes required for the decommissioning of a dam in Ontario, including the technical, economic, social, and environmental issues which must be addressed and accounted for as part of the decision making process.
