The province is activating the Red River Floodway and says overland flooding is possible as significant rainfall continues to hit southern Manitoba.
On Saturday afternoon, the province’s Hydrologic Forecast Center said it expects to activate the Red River Floodway later in the day to manage water levels in Winnipeg.
The city is currently among the parts of southern Manitoba placed under a rainfall warning.

The floodway had not been operating due to low flow rate. Last week, officials had anticipated starting it up again as early as May. However precipitation weekend changed that timeline.
“Water levels on most tributaries in the Red River basin and along the Red River main stem are rising quickly in response to the rainfall and will continue to rise over the coming days,” the province said in a news release.
“Daily average temperatures are forecast to drop below zero early next week, which will slow down the melting of the remaining snow.”
The province said most of central and southern Manitoba basins have already had up to 40 millimeters of precipitation, with 30 to 50 millimeters more expected over the rest of the weekend. The province warned some areas could get up to 80 mm of precipitation by Monday afternoon.
The province said an overland flood warning has been issued for southern Manitoba. It said ditches and waterways are still covered in ice or filled with snow, limiting the water flow and potentially causing flooding.
“Citizens are advised of the potential for the sudden rise of water levels in these areas,” the province said.
