It’s time to prepare for warmer weather as lakes and rivers begin to thaw after a long winter.

Dufferin Ontario Provincial Police (OPP) say rising temperatures together with melting snow and spring rain lead to increased water levels and localized flooding throughout the province.

Key Points

Stay away from riverbanks: Riverbanks become unstable and slippery during the spring thaw. Fast-moving water carries dangerous floating debris, such as ice chunks, construction materials, tree limbs, etc. People and children are cautioned to keep a safe distance from all waterways.

Check your equipment: Early March is an excellent time to ensure your generator is in proper working order. Test sump pumps to confirm they are functioning and consider having extra sandbags on hand should water levels rise. Being proactive can help reduce potential property damage.

Generator safety: When using a gas-powered generator or water pump, ensure the area is well-ventilated to prevent carbon monoxide poisoning. Never operate these devices indoors or in enclosed spaces.

Photo safety reminder: While high water levels may catch your eye, getting too close to waterways or standing on bridges and riverbanks for photos can put your life at risk, as well as the safety of first responders.

Plan accordingly: If you live in a flood-prone area, take proactive steps now to protect your property. Stay informed, monitor local weather alerts and follow the guidance of local officials.
