The Ottawa River could rise 50 centimetres above peak levels seen during the devastating flooding of May 2017, officials now warn.

Under the worst-case scenario, record-high water levels could be reached in some areas by the middle of next week, according to the latest forecast.

The updated prediction is based on data from the Ottawa River Regulation Planning Board (ORRPB), which controls reservoir levels along the length of the river basin. It comes less than 24 hours after Ottawa Mayor Jim Watson declared a state of emergency based on a prediction of levels rising 11 centimetres over the 2017 peak.
