On March 9, 2026, Cataraqui Conservation issued a Flood Watch for inland lakes and streams across the Cataraqui Region, including Kingston and Brockville. The alert comes as a combination of melting snow and forecasted heavy rain threatens to overflow local watercourses.
Weather reports suggest that between 23 and 45mm of rain will fall between March 10 and March 12, 2026. This rainfall is arriving during the “spring freshet,” which is the time of year when large amounts of winter snow melt and run into local lakes and rivers.
Several specific areas are already seeing record water levels for this date. According to the Cataraqui Region Conservation Authority, Wilton Creek, Millhaven Creek, Collins Creek, and Lyn Creek have all reported all-time high flows for March 9.
While officials do not expect widespread flooding at this time, they are warning residents to watch for water in low-lying areas. Some roads may also be covered by water if drainage pipes become overwhelmed or at locations where roads cross over creeks.
There is also a risk that thick ice from the winter could break up and jam, causing water to back up and flood or damage shoreline docks. The Flood Watch is expected to stay in effect until March 18, 2026, and residents are advised to stay away from fast-moving water and dam structures.
