Addition of a line of floating pontoons and riprap to breakwater 301 at Grosse-Île harbour, Magdalen Islands

The project includes work on the current breakwater to allow the anchoring of floating pontoons at the inner end of breakwater 301. The work also includes raising the current riprap of the breakwater to allow better protection of users in this new sector of the harbor with pontoons.


This map is for illustrative purposes. The markers represent the approximate locations based on available data. More than one marker may be identified for a given assessment.
