Black Rapids Lock 13 | City of Ottawa

Black Rapids Lock 13, located in the Nation’s Capital, is considered a cultural resource of national significance, meaning that it has a direct relationship with the reasons for the designation of the Rideau Canal as a national historic site. Timber lock gates were installed at the lockstation in 1969 when the lock was also mechanized. The intent of this project is to repair masonry and concrete in the lock chamber, to replace the lock gates which have been in place for 47 years of service and to upgrade the hydraulic operating system for this lock. This project was previously announced.
