Mississagua Lake Dam Replacement
May 25, 2018 - Community Update: Update on Construction
In 2018, Parks Canada completed the replacement of the dam at the outlet of Mississagua Lake in Peterborough County.
Initially announced in June 2015 as a major rehabilitation; this work was changed to a full replacement following further analysis of the dam site and the state of the previous dam's concrete.
The new dam was constructed immediately downstream of the previous dam and ties into the repaired overflow weir. As part of this project the dam’s height was lowered, a raised catwalk was added to the weir, and a service gain was added to the dam. Public access across the dam was maintained, however, this access is now separated from the operating and service gains.
About the Mississagua Lake Dam
The current dam at Mississagua Lake dates to 2018 and replaced a concrete dam that had been in place since the 1930s. Earlier dams built in this area were constructed using timber cribs. Remnants of the timber crib dams can still be seen in the water upstream of the dam site.
The replacement of the Mississagua Lake dam is part of the Government of Canada’s unprecedented $3 billion investment to support infrastructure work to heritage, visitor, waterway, and highway assets located within national historic sites, national parks, and national marine conservation areas across Canada.
