MVCA Flood Watch Statement – April 2, 2025

From the Mississippi Valley Conservation Authority

A Flood Watch Statement indicates that flooding is possible in specific watercourses or municipalities. Municipalities, emergency services and individual landowners in flood prone areas should prepare.

Weather forecast: Forecasts are calling for a substantial precipitation event beginning overnight and continuing through Thursday. A mix of rain and snow is expected, with totals ranging from 10 to 20 mm. Temperatures on Thursday are anticipated to reach the mid-teens.

Watershed conditions: Water levels and flows across the Mississippi Valley Conservation Authority (MVCA) jurisdiction are currently elevated due to runoff from snowmelt, which has been intensified by recent rainfall and warmer temperatures. With the ground already near saturation, it has limited capacity to absorb any additional rainfall. The recent snowfall over the weekend will contribute to increased runoff in the coming days.

Risks: Springtime water levels and flows are expected to rise due to the ongoing weather conditions, with this trend continuing into next week. While widespread flooding is not anticipated, flooding in low-lying areas and areas with poor drainage is possible. Rivers and streams remain high with fast flowing water. In areas with ice cover, the ice is likely to weaken and break up, increasing the risk of ice jamming.

Actions: Residents in flood prone areas are advised to maintain close watch on water levels and flows and take the necessary precautions to protect their property by:

• Ensuring sump pumps are clear, in good working condition and have a backwater valve.
• Having a portable generator and backup pump available.
• Ensuring downspouts are clear and the outlet is at least 3 meters from any structure.
• Removing or securing items that might float away if flows increase.
• Keeping emergency phone numbers handy.
• Familiarizing yourself with your municipality’s emergency preparedness plan.

Duration: This message is in effect until 12 pm April 7, 2025 or until an update has been issued.
