Manitoba flood bulletin #6: April 17, 2014

Province of Manitoba media bulletin

Summary

  • Temperatures are forecast to rise through the Red River Valley in Manitoba over the next few days, with five to 15 millimetres of precipitation over Friday and Saturday.
  • The crest of the Red River is now predicted to reach Emerson Friday or Saturday with a flow rate of approximately 35,000 cubic feet per second (cfs). Depending on the total precipitation over that time, the crest is expected to reach Winnipeg with a flow of approximately 40,000 cfs about four to five days after it reaches Emerson.  The Red River from Emerson downstream to Winnipeg remains within its banks along its entire length and ice cover remains intact.
  • The Manitoba government is working closely with the City of Winnipeg in preparing for the crest on the Red River.
  • The Manitoba government, in conjunction with the city, may stage equipment at strategic locations in the city and has identified several potential launch sites for the Amphibexes to ensure a rapid response if the threat of ice jams increases.
  • The province also has considerable flood-fighting supplies available to assist the city if requested, including water-filled flood barriers, Hesco barriers and sandbag-making machines.
  • The City of Winnipeg reports sandbags have been made available to homeowners whose properties are currently at risk.
  • A high water advisory continues for the Whitemud River, from Steel Bridge to Lake Manitoba due to the potential for ice jams.
  • A high water advisory continues for the Assiniboine River, from Griswold to Portage la Prairie due to the potential for ice jams and associated flooding.
  • The Portage Diversion is operating for management of ice on the lower Assiniboine River.  Channel flows are near 2,950 cfs.  Portage Reservoir inflows and upstream conditions are being monitored to inform operating decisions.

Ice Conditions

  • Ice conditions are being monitored throughout the province.
  • The ice remains solid on much of the Red River outside of the city of Winnipeg and its tributaries.
  • The ice remains solid on much of the downstream reaches of the Assiniboine River and its tributaries.
  • The warming conditions will increase the rate of breakup.  The warmer temperatures may also create surface run-off and pooling or minor localized flooding.

Spring Safety

  • People are reminded to be watchful of local waterways as flood conditions can develop quickly and ice conditions may be unsafe and to stay away from heavy equipment that may be working around waterways, especially if the equipment is in motion.
  • Stay away from ice and water, and not to drive or walk through fast moving water.
  • Call 511 to check road conditions before travelling.

Questions or concerns about flooding or water management should be directed first to the municipal authority.  Anyone with questions about water levels, provincial waterways or provincial water control infrastructure can call 204-945-8373 between 8 a.m. and 4 p.m., seven days a week.
