Watershed Conditions Statement – Flood Watch


Flood Waters May Return on Lower Ottawa River at Ottawa

(WCS - 16/2017)

April 28, 2017 – Weather forecasts are indicating that significant rain could fall at the start of next week that could cause the present decline of flood waters on the Ottawa River to be reversed.


The Ministry of Natural Resources and Forestry (MNRF) has forecast a total rainfall on Sunday and Monday of up to 70 millimetres (mm). Runoff from this rain can be expected to combine with inflows from further north in the Ottawa River watershed and cause flows locally to increase again possibly as high as was reached last week if the full amount of rain is received.


The locations at risk of flooding on the Ottawa River within the jurisdiction of the Rideau Valley Conservation Authority are communities around Lac Deschene (e.g. Grandview Avenue and Britannia) and Boise Village east of Cumberland. Boise Village still has water on the streets which will be increased with the rain.


On the Rideau system, Bobs and Christie Lakes continue to have high water levels that will be increased by the rain.


With water levels expected to increase again, residents need to be aware of the associated dangers. Children need to be kept away from any open water.


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