The still-rising Ottawa River has already set all-time high water records and has not yet peaked.
According to the Ottawa River Regulation Planning Board’s Sunday 5 p.m. update, the river is at record-breaking levels in LacCoulonge, east of Pembroke, Ont., Arnprior, Ont., and Ottawa.
Records for those areas date back to 1985 for Lac Coulonge and 1950 for the other two cities.
Records were broken at Britannia in Ottawa on Sunday when the water level rose two centimetres above the peak set in 2017.
The Hull marina in Gatineau, Que., is expected to break a record in the coming days.
The forecast — which depends on a number of factors and is “subject to a high degree of uncertainty” — says water levels will continue to rise up to 50 centimetres in parts of the city and should peak in Ottawa-Gatineau Tuesday or Wednesday.
The City of Gatineau said water levels were at the 100-year flood threshold in Aylmer, Hull and Pointe-Gatineau, with levels in Masson-Angers to the east less than 10 centimetres from that level.
