The flooding of communities on or downstream from the Ottawa River is breaking some historical records, but this is far from the worst flooding Quebecers have experienced.

The water level on the Lake of Two Mountains surpassed its all-time high on May 3.

As of May 12, 3,641 people had been forced from their homes and 4,485 residences had suffered flood damage in 187 municipalities.

Of the 36 major Quebec floods tracked by the Canadian disaster database, it ranks fourth by number of people affected, after the floods of 1998, 1996 and 1974.
