Forecast for 2023-04-19

River conditions forecasts posted on 2023-04-19 by Ottawa River Regulating Committee

Water levels and flows on the main stem of the Ottawa River are increasing in all locations in response to the rapid melt of the snowpack in the basin. Between Lake Coulonge and the Montreal region, levels are expected to continue increasing today and tomorrow, stabilizing near the major flood level over the next few days. 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. Water levels are currently expected to remain well below historical flood levels on the main stem of the Ottawa River.
