How high the Ottawa River could get: Wednesday's forecast
Dates for predicted water level peaks pushed back again
Water levels on the swollen Ottawa River are now expected to peak later this week in the Ottawa-Gatineau area.
Over the weekend, the river surpassed 2017 flood water levels in Pembroke, Ont., Lac Coulonge, Arnprior, Ont., and west Ottawa's Britannia neighbourhood, setting records in each location except Pembroke.
According to the latest update, the peak water level at Gatineau's Hull Marina will be slightly lower than previously forecast, although it will still be above 2017 levels.
The Ottawa River Regulating Committee, which controls reservoir levels along the length of the river basin, said at 5 p.m. Wednesday the water level in Pembroke is at 113.15 metres above sea level, down three centimetres from Wednesday morning.
They expect it to rise another 45 centimetres to a peak of 113.6 metres on Monday — two days later and 20 centimetres higher than they'd previously estimated.
Lac Coulonge is at 108.94 metres, down 15 centimetres from Tuesday morning. The river reached its peak there on Tuesday at 109.1 metres and is now receding.
Arnprior is at 76.24 metres, down six centimetres from Tuesday morning. However, it could rise another 11 centimetres to a peak of 76.35 metres on Thursday, two days later than predicted in yesterday's forecast.
Britannia in west Ottawa is at 60.69 metres, up three centimetres from Tuesday morning, and could rise another 16 centimetres to a peak of 60.85 metres on Thursday, one day later than expected yesterday morning.
The Hull marina in Gatineau is at 45.16 metres and could rise another 19 centimetres to a peak of 45.35 metres on Friday, one day later than was expected and 15 centimetres lower than yesterday morning.
Thurso, Que., is at 43.66 metres, up three centimetres from Tuesday morning, and could rise another 14 centimetres to a peak of 43.80 metres on Friday, one day later than expected yesterday morning.
And Hawkesbury, Ont., is at 42.73 metres, down two centimetres from Tuesday morning, and could rise another 12 centimetres to a peak of 42.85 metres on Friday, one day later than expected yesterday morning.
