Forecast for 2023-04-17

River conditions forecasts posted on 2023-04-17 by Ottawa River Regulating Committee


Water levels and flows on the main stem of the Ottawa River are increasing in all locations due to the rapid melt of the snowpack in the central and southern parts of the basin. Major flood levels may be exceeded in flood prone areas along the river between Lake Coulonge and the Montreal region starting Wednesday. The major flood level is defined as the level at which one or several streets are beginning to flood, with several houses/buildings or neighbourhoods being affected. Peak river conditions remain dependent on snowmelt and rainfall amounts, but water levels are currently expected to remain well below historical flood levels on the main stem of the Ottawa River.
