Assiniboine River expected to rise as province releases water from Shellmouth Dam

Assiniboine River expected to rise as province releases water from Shellmouth Dam

Water levels on the Assiniboine River and shorelines may create unsafe conditions in the weeks to come as outflow from the Shellmouth dam is increased, Manitoba Transportation and Infrastructure warns. The water level is expected to rise by one to two feet between the Shellmouth Dam and Brandon, 160 km southeast of the dam. The expected rise is the result of water released from the Shellmouth Reservoir to make room for spring's flow. 

Decreasing water levels in Lake of the Woods and Lac Seul

Decreasing water levels in Lake of the Woods and Lac Seul

Lake of the Woods and Lac Seul have been hit hard this year with decreasing water levels. The current level of the Lake of the Woods is 322.75 m (1058.9 ft), which is equal to a 30th percentile (per cent of distribution that is equal to or below it) which is considered normal for this time of the year. This past week the lake water level has fallen by 1cm (½ in), and is still expected to drop further by 1 to 3 cm ( 1 in) over the next week.

St. Lawrence water levels could wash away more than $1B

St. Lawrence water levels could wash away more than $1B

Rising water levels in the St. Lawrence Seaway could cost the economy more than $1 billion, shippers and port operators say. A new study from the Chamber of Marine Commerce warns that opening the floodgates further at a dam in Cornwall, Ont., would wash away between $1 billion and $1.75 billion in revenue for businesses on both sides of the border. A board of control recently increased the flow at the Moses Saunders Dam — the only control point on the St. Lawrence Seaway, which includes the Great Lakes — to allow 10,400 cubic metres of water per second out of Lake Ontario.
