The new dam over the Couesnon will not be able to restore the maritime character of the Mon-Saint-Michel by itself. Other hydraulic works are needed.

To discover the works upstream the dam, check the french section dedicated to them here, and the downstream works here.

These works, starting in 2011, are due to be completed by 2015.
