Shabomeka Lake Dam was built in 1910 and consists of a single concrete sluice and two earth embankments.
The dam is operated in conjunction with the other dams to provide flood control for the lake and downstream areas and maintaining water levels in Shabomeka Lake for recreation and tourism. The dam has undergone major repairs over the years. Due to its age, the dam is experiencing deterioration of the gabion basket wing walls and excess settlement and seepage of the earth embankments.
A Class EA and preliminary dam rehabilitation design was completed in 2017-2019; a detailed design is currently underway, with the dam scheduled for replacement in 2021.
