Hydro-Québec Monitors Saint-Maurice River Flood Risk Amid Heavy Rain in Quebec

Heavy rain across Quebec and parts of Ontario has caused river flows to surge, with the Saint‑Maurice River reaching 1,564 m³/s, far above the typical 340‑550 m³/s for this time of year. Meteorological services forecast 80‑100 mm of rain in hotspots and an additional 50‑60 mm expected, raising flash‑flood risk for low‑lying urban areas and infrastructure.

Hydro‑Québec is closely monitoring the situation, coordinating with regional civil‑security agencies and adjusting its water‑control structures to limit impacts. Annie Beaudoin, Hydro‑Québec’s community‑relations adviser, warned residents to exercise caution near waterways, noting that strong currents can persist even when surface water appears calm.
