Province Advises Outflow from Shellmouth Reservoir to Increase



Manitoba Transportation and Infrastructure’s Hydrologic Forecast Centre reports the outflow from the Shellmouth Reservoir will be increasing today as part of the normal operation to draw down the level of the reservoir in preparation for spring run-off from the upper Assiniboine River.

The outflow earlier today was 100 cubic feet per second (cfs). The outflow will be increased to 200 cfs today and to 300 cfs tomorrow. This will result in an increase in water levels by one and half feet to two feet on the Assiniboine River from the Shellmouth Dam to Russell and by one to one and half feet from Russell to Brandon. The increase will diminish as the river reaches Winnipeg.

The province will continue to monitor conditions in the upper Assiniboine River as well as downstream river levels.
