Update on Flood Risks along the Ottawa River (Mattawa to the Montreal Region)
Press Release posted on 2023-04-28 by Ottawa River Regulating Committee
The Ottawa River Regulating Committee warns that levels and flows along the main stem of the Ottawa River will remain high and are susceptible to further rise over the coming week in all locations due to significant rainfall that is forecast for this weekend. Minor flood levels will likely be exceeded in multiple locations between Mattawa and the Montreal region. Major flood levels may be exceeded in flood prone areas, depending on the amount and location of the received precipitation. Areas of primary concern are identified and described in more detail in the bulletin. Water levels are currently expected to remain well below historical flood levels of 2019 on the main stem of the Ottawa River.
Additional bulletins will be published if flood risk is expected to increase.
