A warning has been issued to stay off the Assiniboine River between Shellmouth Dam and Portage la Prairie.  Manitoba reports flow was being released from the reservoir since the fall in order to increase its capacity for anticipated spring runoff.  However, the target level on the dam has been achieved, and outflows are now being reduced. The ice surface may weaken or crack and become hazardous following the reduction in flows from the Shellmouth Reservoir.
