The Portage Diversion began operating on Friday morning to manage ice and flows on the lower Assiniboine River. Flows in the channel are now at 1,965 cfs and the flow on the lower Assiniboine River is 5,090 cfs. The Shellmouth Reservoir has been drawn down in preparation for spring run-off, and outflows from the Shellmouth Dam will be matched to inflows to preserve reservoir storage for the expected peak flows.
