FLOOD WARNING Issued for Ottawa River-Constance Bay – FLOOD WATCH for Mississippi Valley Watershed


May 5, 2017 MISSISSIPPI VALLEY WATERSHED—Mississippi Valley Conservation Authority (MVCA) has issued a FLOOD WARNING for its jurisdiction along the Ottawa River, specifically for the Constance Bay area. Residents are being cautioned that water levels are expected to continue to increase over the weekend with rain amounts of approximately 40 mm forecasted. Levels are not expected to peak until early next week. Of greatest concern is the Bayview Drive area in Constance Bay where access could become restricted.

Due to rising levels across the Mississippi River system, a FLOOD WATCH has been issued for the Mississippi Valley watershed. Levels on Dalhousie Lake are expected to get close to the height they were earlier this spring and could exceed those levels by 5 to 10 cm based on the forecasted rainfall over the next few days. Levels on the Clyde and Fall Rivers and on Mississippi Lake are not expected to get as high as they were a couple of weeks ago. Water levels remain very high across the upper portion of the Mississippi Valley watershed so it will be at least two weeks before levels begin to return to normal.

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 FLOOD WATCH 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).

The Mississippi Valley Conservation Authority flood forecasting and warning program monitors weather conditions, snowpack water content, estimates expected river flows and water levels and issues flood advisories or warnings as required. MVCA provides early warning and continuous monitoring to municipal and provincial emergency response personnel through a flood event.
