Water Levels to Increase in Lower Ottawa River


(WCS - 20/2017)

May 4, 2017 – Rain forecast for Friday and Saturday is expected to cause water levels to continue to rise through the weekend.


This Flood Warning applies to areas around Lac Deschene, at Petrie Island and at Boise Village to the east of Cumberland.


Another rain event is forecast for Friday and Saturday with a possible two day total of 35 millimetres to as much as 70 mm. Increased water levels will occur whatever the total rainfall is. Levels could increase by 25 to 35 centimetres depending on timing, location and amount of rain. The rain is forecast to taper off on Sunday so a peak can be expected late on Sunday or on Monday.


Attempting to drive or walk in water more than 30 centimetres depth of water is not advised. Parents need to inform children about the dangers of going near flooded areas and fast moving water in streams and ditches.


Conservation Authority staff will continue to monitor conditions and will issue updates as warranted.
