A conservation authority in eastern Ontario says water flows in the Moira River east of Toronto have reached the same levels as major flooding in 2008, but have stabilized as Belleville residents frantically throw down sandbags and hope for fair weather.

Jennifer May-Anderson with Quinte Conservation says overnight rain wasn't heavy enough to trigger large-scale flooding and that the river hasn't crested like it did six years ago.

She says the water level, though at a concerning high, should stay stable over the next few days if the amount of rain upstream remains light.

Belleville and other Quinte Region areas are under flood warnings, and Belleville has been under a state of emergency with volunteers helping pack sandbag walls around homes in low-lying areas that are at the greatest risk.

Belleville says more than 70 homes have been sandbagged as of Sunday and that some 480 volunteers are pitching in.

City spokesman Aaron Bell says no homes have been rendered uninhabitable, though there has been one evacuation due to concerns for the condition of a resident inside. Bell says no more evacuations are expected.

Ottawa, southern Quebec brace for flooding

Environment Canada has ended its weather warnings for Ottawa, Gatineau and areas of eastern Ontario, but residents affected by flooding are still on alert with a thunderstorm in the forecast for Monday.

But the organization admits the total amount of precipitation expected to hit the region is unclear.

In southern Quebec, rains threaten to raise river water levels and the risk of floods even higher.

Up to 45 millimetres of rain could fall in some regions Sunday.

Rain is expected to continue through Tuesday, according to Environment Canada.
