The Red River Floodway is now in operation, taking some of the river water around Winnipeg into the diversion channel. The control structure was activated shortly before 10 a.m. Friday by Manitoba Infrastructure Minister Doyle Piwniuk, who posted about it on his Twitter account. The province uses the floodway — a 47-kilometre channel between St. Norbert and Lockport that runs along the eastern edge of Winnipeg — to divert some of the Red's flow and maintain a manageable level through the city in flood season.
