Flood Watch Termination — Lower Ottawa River

20-Apr-2020 20-Apr-2020

The Flood Watch issued on April 9, 2020 is being TERMINATED. A Water Safety Statement is in effect as all areas are experiencing high spring flows which are typical for this time of year.

The Ottawa River Regulation Committee has indicated that levels are decreasing along the main stem of the Ottawa River from Pembroke down to the Montreal region as runoff from melting snow in tributaries decreases. It is expected that levels will continue decreasing to normal spring freshet levels as no major precipitation is forecasted over the next few days.

Residents are advised to stay away from watercourses where flows are high and where banks might be unstable. Parents are encouraged to explain dangers to children.

The Mississippi Valley, Rideau Valley, and South Nation Conservation Authorities monitor water levels and weather forecasts with the Ministry of Natural Resources and Forestry as part of the Flood Forecasting and Warning Program. Updates are provided as conditions change.

The Ottawa River Regulating Committee will be reassessing forecast conditions and providing hydrological condition updates on its website daily at
