A FLOOD WATCH is now in effect for Mississippi Lake. The FLOOD WARNING for the upper Mississippi Valley watershed including Mazinaw Lake, Little Marble Lake, Marble Lake, Ardoch Village, Snow Road Village and Dalhousie Lake continues.
Water levels across most of the upper watershed have stabilized. There is significant rainfall in the forecast for Wednesday and Thursday which could cause levels to increase again. Levels in the Snow Road area above High Falls and in Dalhousie Lake have begun to drop and are expected to stabilize as flows from the upper watershed reach that area. The levels may increase again later this week if the forecasted rainfall amounts occur.
Flows in the Clyde River watershed peaked on the weekend and are dropping. The forecasted rainfall is not expected to cause this river to increase although it may cause the level to stabilize for a couple of days. Flows in the Fall River have just peaked and are expected to start dropping through the early part of this week.
Flows within the Indian and Carp Rivers are not expected to rise significantly and they continue to drop steadily.
Water levels on Mississippi Lake are still expected to increase another 20 to 25 cm over the next two days bringing levels to 135.20 to 135.25 m. Any significant rainfall could cause this lake to increase. Flows and levels throughout the watershed will remain higher than normal over the next two weeks.
Residents are strongly urged to remind children of the dangers of hypothermia from cold water and playing near fast flowing rivers and creeks.
Residents in low lying areas, historically susceptible to flooding, should take the necessary precautions to protect their property, such as:
- Ensuring sump pumps are clear and in good working condition
- Removing or securing items that might float away as flows increase
This FLOOD WARNING UPDATE is valid through May 3, 2018. Additional statements will be issued when or if conditions are expected to change significantly from this outlook.
Daily water levels and flows are available on the MVCA website at http://mvc.on.ca/water-levels/
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.
