Lock 7 - Glen Ross
Constructed: 1908-1914

Originally called Chisholm’s Rapids, the construction of this lock was the smallest contract in the Ontario - Rice Lake division. The Canadian General Development Company replaced the old 1841 masonry lock with a larger concrete lock and the old wooden dam was replaced with a new concrete dam upstream. An extensive concrete-lined navigation channel above the lock parallels the Trent River.
