Province Advises Outflow from Shellmouth Reservoir will Increase



Manitoba Infrastructure’s Hydrologic Forecast Centre reports the outflow from the Shellmouth Reservoir will be increasing on March 8 as part of the normal operation to draw down the level of the reservoir in preparation for spring runoff from the upper Assiniboine River.

The current outflow is 300 cubic feet per second (cfs). The outflow will be increased to 500 cfs today. This outflow increase will result in about a one-foot level increase on the Assiniboine River from the Shellmouth Reservoir to Russell, and a half-foot or less level increase 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.
