– The first phase of work at Edmonds Lock 25, Overflow Dam and Weir on the Rideau Canal National Historic Site is now complete. This phase of work focused on stone masonry repairs to the lock and overflow dam, repairs to the earth dam, installation of the safety boom, as well as improvements to the roadway access to the dam from County Road 43. The site is currently undergoing restoration which will continue through the opening weekend of the 2017 navigation season.

In fall 2017, phase two of construction at Edmonds Lock is scheduled to begin. This phase will focus on masonry repairs to the weir. The full project is expected to be completed by spring 2018. The Edmonds Lock 25 project is extending the life of these important waterway assets and ensuring this site will welcome visitors for years to come.

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.

About Edmonds Lock 25, Dam and Weir

Edmonds Lock, Dam and Weir were constructed in the late 1820s to early 1830s. The lock was created with a 2.64 metre (eight foot, eight inch) lift, built on a clay foundation and wooden floor. A stone arch overflow dam was built with a weir installed to reduce the chance of floods. In the early 1840s, a stone lockmaster's house was constructed at the site then replaced with a two-storey house in 1905.
