April 7, 2020 - Community Update: Construction Update: Temporary Bridge Opens for Vehicles

Ranney Falls Dam 10 will begin  in December 2019 with contractor mobilization and site preparation. Construction is to begin in January 2020 and completion is expected in Fall 2021. The project  will expand the dam with two additional sluices and a  new dam control building. The newly expanded dam will increase water discharge capacity which will  improve  water management capabilities and reduce the likelihood of flooding.

As construction begins, Parks Canada will be working with the Municipality of Trent Hills and utility service providers to temporarily relocate utility services including sewer, gas, hydro, and telephone. Residents will not be impacted with this relocation and access to amenities on the West side of the dam will not be impacted.

Residents are advised that lane use will be reduced to a single lane on Trent Drive and intermittent closures may occur. The Ranney Falls Swing bridge will be available at full load rating for duration of the construction project. Parks Canada would like to thank residents for their continued patience and more information will be released as the project unfolds. For residents and visitors that would like regular updates, please send an email to ont.trentsevern@pc.gc.ca with “Ranney Falls Dam 10” in the subject line.  

History of Dam 10

Dam 10 was originally built in 1925 and included a roadway bridge on top of the dam. The  dam and bridge were both re-constructed in 1980 just downstream of the original dam. This current dam is mechanized and has a total of six sluice gates to control the water levels and flows. The bridge over the dam is currently owned and maintained by the municipality of Trent Hills. 

Infrastructure Program

This project is part of Parks Canada’s unprecedented $3 billion dollar investment over 5 years 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. These historic investments will mitigate health and safety risks, halt the loss of nationally significant built heritage and stimulate the economy in communities across the country.
