"Double Trouble" Could Drive River To Historic Highs This Week

Two troubling factors have pushed the forecast for the Ottawa River peak farther into the future yet again, with a warning of more rising levels this week.

Heavy rain forecast for Thursday and ongoing releases from full reservoirs upstream in Temiskaming are contributing to the rise in levels.

And this time, river regulators say the water could hit higher levels than what have been measured in recent history.

Pembroke Area Peak:  Friday 

The Ottawa River Regulating Committee now says the peak in the Pembroke area will not be reached until late Friday.

Before then, the river is expected to rise another 22 centimetres in the Pembroke area, compared to its Wednesday level, to 113.75 metres above sea level.   

That would be 8 centimetres higher than its historic peak year, which was set back in 1960.

Westmeath / Lapasse Area Peak:  Saturday

In the area farther downstream from Pembroke, known as Lac Coulonge, the committee expects the peak to happen on Saturday.

The river is expected to rise another 40 cm from its Wednesday level by then, surpassing what have already been historic levels this year by another 20 cm.
