More than 500 families had registered with the Red Cross and left their homes. About 120 were staying at shelters in the Fredericton area.
But many others have simply abandoned their homes to stay with friends and relatives, so it remains unclear how many have been displaced.
At one point, officials said about 1,300 homes were threatened by the river, but they couldn't be more specific about the extent of damage or how much it will cost for the cleanup.
In the Fredericton area, schools, businesses and more than 50 roads were closed or partially blocked as the river reached its crest.
