Watershed Conditions Statement – Flood Warning, Ottawa River

May 1 Rain Causes Return of Flood Waters in Lower Ottawa River

 

(WCS - 18/2017)

May 2, 2017 – Rain on Monday has pushed water levels in the Ottawa River above the peak reached last week.

 

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

 

A short-lived peak can be expected on Wednesday. Rain, possible on Thursday but probable for Friday and through the weekend, is expected to increase levels further. Peak elevation at Britannia last week was 59.924 metres above sea level. At 10:00 this morning, the level was 60 metres. Downstream of the Chaudiere Falls the peak level last week was 44.09 metres. The measurement this morning was 44.199 metres and increasing. At Thurso last week, the peak was 42.84 compared to 42.83 metres this morning but that will continue to rise as water moves through the system.

 

Flooding that has occurred in Boise Village has been mainly limited road access. The increase in levels from the Monday rain could cause more property flooding. Access to Petrie Island continues to be an issue. As water levels increase, flood control measures in Britannia will be tested and lower lying properties can be expected to be inundated.

 

Attempting to drive or walk in water more than 30 centimetres deep 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.
