Flood Outlook - Ottawa River (Cumberland, Britannia Bay, Constance Bay) Ottawa River Levels Stabilized, Expected to Start Receding

May 10, 2018 – The Mississippi Valley and Rideau Valley Conservation Authorities are advising residents that water levels appear to be stabilizing. Some nuisance flooding (Petrie Island, Boise Wood) has occurred. Rain that fell this morning was not enough to have an impact and there is no rain forecast for the next five days that would cause levels to increase again. Water levels will gradually decline to normal summer levels over the next two weeks barring the development of a significant weather system..

Note that streambanks are slippery along the Ottawa River, water is fast moving and still very cold. Children should be informed about the hazards and kept away from all watercourses as levels fluctuate with the spring weather.

This message will lapse on May 15, 2018 unless conditions warrant further messaging.
