Assiniboine River

  • Overbank flooding of agricultural land along the Assiniboine River is occurring from Shellmouth Dam to Brandon.  Approximately 30,000 acres of agricultural land is impacted.
  • Continued high flows on the Assiniboine River and increased flows on the Red River from U.S. points will likely leave The Forks walkway under water until at least the end of May.
  • City of Brandon:
    – High water levels on the Assiniboine River have inundated the soccer pitch along First Street with water. Conditions are currently stable.
  • The water level on the Shellmouth Reservoir has increased to 1,409.4 feet; the summer target level is 1,402.5 ft. and the spillway is at 1,408.5 ft.  As the water level has exceeded the spillway elevation, flows are occurring over the spillway; spillway flows will increase or decrease as the reservoir level rises and falls.
  • Inflows to the reservoir are approximately 8,730 cubic feet per second (cfs) and outflows are at 5,780 cfs.  Outflows include 5,260 cfs of conduit flow and 520 cfs of spillway flow.
  • As of this morning, flow on the Portage Diversion is 4,060 cfs and flow on the Assiniboine River downstream of the diversion is 10,040 cfs.  The operation plan for the Portage Diversion is to hold the flows on the lower Assiniboine River to approximately 10,000 cfs.

Eastern Region

  • A flood watch has been issued for Brereton Lake in the Whiteshell Provincial Park.
  • The lake level is high but is being regulated by operating the control structure on the lake.
  • There is potential for flooding to develop on the lake itself and downstream.  Conditions are being monitored regularly.
  • Streams in the region are stable and are within bank.
  • Nutimik Lake is rising as a result of flows from the Winnipeg River.

Emergency Response

  • Manitoba Emergency Measures is working with flood-impacted communities in northern Manitoba.
  • States of local emergency continue in the RMs of Westbourne and Hillsburg, and the towns of The Pas and Roblin.
  • The province has deployed flood-fighting and mitigation equipment strategically across the province.  Regional staff are supervising and monitoring water levels in affected areas.

  • to be watchful of local waterways as flood conditions can develop quickly and ice conditions may be unsafe,
  • to avoid crossing areas with broken ice and surface water,
  • not to drive or walk through fast-moving water, and
  • to call 511 to check road conditions before travelling.
