The Manitoba government is continuing to monitor the Red River Valley in anticipation of potential high-water situations, said Infrastructure Minister Ron Schuler when he released the second Spring Thaw Outlook for 2020.
“Our outlook remains similar to the first outlook we released in late February and our focus continues to be on the Red River this spring,” said Schuler. “Forecasters are expecting a significant inflow of water from the northern United States and they expect high water levels similar to last spring, barring a major early April storm with substantial precipitation or a fast melt.”
The second Spring Thaw Outlook of 2020 reports the Assiniboine River basin and other rivers are expected to remain mostly in-bank, with possible over-bank high water covering agricultural land at a few locations.
Manitoba Infrastructure’s Hydrologic Forecast Centre reported that with favourable conditions, water levels similar to the spring of 2019 are expected. Last year, the Red River Floodway was put into service but Provincial Trunk Highway (PTH) 75 from Winnipeg south to Emerson remained open.
Average weather conditions in spring 2020 would result in water levels similar to 2006 on the Red River, according to forecasters. In that year, PTH 75 was closed for 18 days. Unfavourable weather could lead to a run-off nearing 2011 levels. In 2011, PTH 75 was closed for 28 days.
Minister Schuler noted that considerable provincial resources are involved in the fight against the spread of COVID-19 and officials have contingency plans in place if the approaching spring thaw requires preparations for high water management.
“The government has also recently announced the most emergency-ready budget in Manitoba history with additional financial provisions for COVID-19 and any other emergencies we may face,” said Schuler. “Manitobans have dealt with many emergencies in the past, and we will be prepared for any high-water event that may develop over the coming weeks.”
