Low water levels in Quebec rivers spur navigation warnings, watering bans
Navigation hazards on the St. Lawrence River and water use restrictions in Montreal stem from low river levels caused by dam operations and recent dry weather, officials said.
- On August 13, 2025, The Canadian Press reported warnings about low water levels affecting navigation and water use in Quebec waterways.
- The warnings followed a Canadian Coast Guard notice on August 6 that buoys between Montreal and Trois-Rivières may be off position due to drought and dam operations.
- Authorities imposed water restrictions in Montreal boroughs west of downtown and urged caution for boat pilots who must subtract 10 centimetres from river depth charts.
- Kevin Lajoie noted speed limits on Lake St. Louis were lowered, while Francis Fortin-Legault explained low water reduces quality and stresses water-treatment systems.
- These measures aim to prevent navigation hazards and preserve water resources during a drier than normal August with ongoing low river levels.
