Province Advises Outflow from Shellmouth Reservoir Will Increase

Manitoba Infrastructure’s Hydrologic Forecast Centre reports the outflow from the Shellmouth Reservoir will be increasing today due to anticipated run-off from the upper Assiniboine River.

The current outflow is 52 cubic feet per second (cfs). The outflow will be increased to 600 cfs. This will result in a two-to-three-foot level increase on the Assiniboine River from the Shellmouth to Russell and one-to-two-ft. level increase from Russell to Brandon. The increase will diminish as the river reaches Winnipeg.

River users should be cautious. However, the rise in water levels is not expected to impact properties and the river will remain within its banks.

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