FLOOD WARNING – MISSISSIPPI VALLEY WATERSHED – May 6, 2017
May 6, 2017 MISSISSIPPI VALLEY WATERSHED—Mississippi Valley Conservation Authority (MVCA) has issued a FLOOD WARNING for the Mississippi River from Mazinaw Lake downstream to Dalhousie Lake.
Due to significant rainfall overnight in the western portion of the watershed, levels on all of the upper lakes have increased dramatically and are nearing or have exceeded flood stage. With additional rainfall in the forecast for today and tomorrow, levels are expected to continue to increase over the next few days. Dams are being operated to try to mitigate conditions both upstream and downstream. Levels on Dalhousie Lake are expected to continue to increase through the weekend by as much as 30 – 40 cm and could reach those experienced in 2014. Water levels remain very high across the upper portion of the Mississippi Valley watershed so it will be at least two to three weeks before levels begin to return to normal. Flows and levels on the Clyde and Fall Rivers are increasing but are not expected to get as high as earlier this spring and should peak by Monday. Water levels on Mississippi Lake are expected to increase 30 – 40 cm over the next 4 to 7 days bringing them close to where they were earlier this spring.
Residents are being advised to stay away from watercourses where flows are high and where banks might be unstable. Parents are encouraged to explain these dangers to their children.
The FLOOD WARNING for the Ottawa River and this FLOOD WARNING for the Mississippi Valley watershed are valid through May 8, 2017. Additional statements will be issued when or if conditions are expected to change significantly from this outlook.
Only if it is safe to do so, the public is encouraged to share photos of water conditions in their area via MVCA Facebook (Mississippi Valley Conservation Authority) and Twitter (@MVCAuthority).
