The outflow from the Shellmouth Reservoir was increased beginning on Friday, going from 300 to 500 cubic feet per second.
The increase is part of the normal operation to draw down the level of the dam in preparation for spring runoff from the upper Assiniboine River.
The province says because of the water flow increase, water levels from the Shellmouth Reservoir to Russell will rise by about a foot, while the levels from Russell to Brandon will go up by six inches or less.
