Long Pond Lake Rip-Rap - Canadian Forces Base (CFB) Valcartier

The Department of National Defence (DND) is proposing a riprap of the sill at Canadian Forces Base (CFB) Valcartier. The old structure serving as a dam gave way, and the level of the lake dropped by 30-60 cm. Long-term effects could be erosion of the sill, if it is washed away would affect a multitude of lakes as well as road infrastructure.

Latest update

September 21, 2021 – The public comment period on the project is closed. The Department of National Defence is considering comments received to help inform its determination on whether the carrying out of the project is likely to cause significant adverse environmental effects.
