The Portage Diversion will be closed Saturday due to declining water levels on the Assiniboine River but the floodway will remain open, according to a release by the province. A flood warning continues for the Red River from Emerson to the Red River Floodway channel inlet. The province said the Red River is expected to peak sometime between April 20-22 in Emerson with peak flows ranging from 20,000 and 24,300 cubic feet per second.
