Province Advises of Increased Outflow from Shellmouth Reservoir



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 runoff from the upper Assiniboine River.
 
The current outflow is 240 cubic feet per second (cfs). The outflow will be increased to 500 cfs today and to 700 cfs on Dec. 13.
 
This increase in outflow will result in a one-and-a-half to two feet level increase on the Assiniboine River from Shellmouth to Russell and one to one-and-a-half feet from Russell to Brandon. The increase will diminish as the river reaches Winnipeg.
 
The province will continue to monitor conditions on the upper Assiniboine River as well as downstream river levels.
