The Haut-Richelieu has exclusive jurisdiction over all the rivers of the territory. Under this jurisdiction, the RCM proceeds to the maintenance and management of rivers and any action deemed necessary.

No action is permitted in the shoreline of a watercourse without the necessary permits have been issued in advance by local municipalities. Before undertaking any work near a stream, check regulations with your local municipality.

The Act makes no distinction between the rivers constant or intermittent and those created or modified by human intervention (See PDF below for the definition of a watercourse ).Extract from the Municipal Powers Act (RSQ, chapter C-47.1, section 103)


Since 1 January 2006, the entry into force of the Municipal Powers Act also confers on the MRC's obligation to complete the work required to restore the normal flow of streams within its jurisdiction when it is informed the presence of an obstacle that threatens the safety of persons or property.

Riparian owners have the primary responsibility for ensuring that no embarrassment is not found in rivers. The MRC must be involved, at the expense of such owners, if they do not act and that damage is imminent.

To report an obstruction or a nuisance in a river, immediately contact the designated person within each municipality.

On December 8, 2010, the Haut-Richelieu adopted the Regulation 468 , which replaces Regulation 449 and heading:

Note: For some procedures, authorization must be obtained from various levels of government. Be sure to obtain all necessary permits before working in or around a river!
