MVCA extends flood warning to include the upper Mississippi River watershed

April 30, 2018 by

MVCA LOGOThe Mississippi Valley Conservation Authority is extending the area encompassed by the FLOOD WARNING to include the upper Mississippi Valley watershed including Mazinaw Lake, Little Marble Lake, Marble Lake and Ardoch Village. With the weekend rainfall, flows and levels are expected to continue to increase into the week.

Levels in the Snow Road area above Dalhousie Lake have begun to drop but may increase again with additional rainfall.

Flows in the upper Clyde River and the Fall River watersheds had begun to drop but may also start to increase again depending on how much rainfall those areas receive.

Flows within the Indian and Carp Rivers have been dropping steadily over the last two days but are beginning to increase again.

With the increased flows in the upper watershed, residents on Mississippi Lake can expect levels to increase as much as 40 cm over the next three to four days bringing levels to 135.20 m. This would be comparable to levels reached on the lake in 2017. Flows on the Mississippi River are not expected to peak until later this week. 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 April 30, 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/
