On March 3, 2026, Cataraqui Conservation issued a spring flooding outlook for residents in Kingston, Ontario, noting a significant potential for flooding. The alert comes as a deep layer of snow and upcoming warm weather create the potential for water to rise quickly across the region.
The latest snow surveys from March 2, 2026, show that the current snowpack holds double the amount of water usually seen at this time of year. In Kingston and Battersea, snow levels are especially high, measuring about 260 per cent of the average seen over the last 30 years.
Weather forecasts show daytime temperatures will stay above freezing from March 6 to March 11, 2026. This stretch of warmth, along with predicted rain, could cause the heavy snow to melt fast and lead to flooding in low-lying areas and along shorelines.
Residents are encouraged to check their property drainage and prepare for potential impacts on roads and shorelines. The conservation authority will continue to monitor the situation and provide updates as the melt continues.
