Expecting Major Flooding on the Ottawa River

Press Release posted on 2023-04-17 by Ottawa River Regulating Committee

The Ottawa River Regulating Committee warns that levels and flows along the Ottawa River continue to rise rapidly due to on-going snowmelt combined with rain runoff in the central and southern portions 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, April 19. 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. Additional bulletins will be published if flood risk is expected to increase further.
