Water levels have dropped below flood stage in most areas of the St. John River in what has become the worst flooding event ever recorded in New Brunswick.

The Emergency Measures Organization says only in the Jemseg area will levels be just above flood stage.

The Trans Canada Highway between River Glade and Oromocto finally reopened Friday after being closed for a week but dozens of roads remain closed due to flooding.

The Canadian Armed Forces has deployed 60 members to assist the provincial government with flood cleanup.

Almost 1,700 residents have registered with the Red Cross as evacuees and many who have returned home are finding heavy water damage to homes and cottages.

Floodwaters covering the road near Jemseg have forced the closure of the Trans Canada Highway between Moncton and Fredericton.

The Emergency Management Organization says the road could be closed for several days until water levels recede.

A long detour forces travellers to go through Saint John via Routes 1 and 7.

EMO says the water continues to rise along the southern St. John River and may exceed levels last seen during the historic 1973 flood.

Flooding continues in Fredericton where water levels have increased again to a point where the benchmark of 2008 was reached.

New Brunswick’s Emergency Measures Organization is warning levels are rising along the southern region of the St. John River basin.

Residents from Jemseg and Gagetown to Quispamsis and Saint John are being told to be on high alert and expect flooding if it has occurred in the past.

Several neighbourhoods of Saint John are under a voluntary evacuation (see map above) due to flooding, road closures and rising waters along the river.

Recent heavy rains and melting snow have caused flooding along the St. John River Valley especially in Fredericton.

Streets and parking lots in the downtown core have been left underwater.

Emergency Management Organization officials say the river was 1.7 metres above flood stage in Fredericton by late Saturday – a level not seen since the major flood of 2008.

Communities further downstream have also been flooded including Maugerville and Jemseg with some roads impassable due to high water levels.

Much of New Brunswick was spared the worst of a low pressure system which delivered heavy rain and created flooding over the weekend especially along the St. John River.

Environment Canada says the extreme southern half of the province had the most rain with more than 100 mm in some areas and unofficially almost 180 mm (about two months worth) fell in Mechanic Settlement, near Fundy National Park.

Moncton got off relatively easy with 40 mm of rain while Saint John had 70 mm and Fredericton reported 80 mm.

The Emergency Measures Organization says water levels should remain high but steady for the rest of this week with more rain on the way.
