After steadily rising for more than a week, water levels along the southern portion of the St. John River have surpassed the historic flood in 1973.
Environment Canada is forecasting more rain for Southern New Brunswick with up to 20 mm possible by Monday after 30 mm fell Friday and early Saturday.
The Coast Guard and the Department of Fisheries and Oceans have provided vessels to help with evacuations and Transport Canada has deployed surveillance aircraft.
Almost 1,000 people have registered as evacuees with the Red Cross.
Many roads have been closed by the flooding including the Trans Canada Highway between River Glade and Oromocto – the detour through Saint John adds one hour of travel time between Moncton and Fredericton.
