Residents across the Waterloo region are being advised to use caution near local waterways as rising water levels follow significant rainfall. The Grand River Conservation Authority issued a watershed conditions statement for water safety on April 14, 2026, which remains in effect as more rain is expected through Thursday, April 16.
The conservation authority reports that between 20 and 40 millimetres of rain have already fallen in the northern parts of the watershed, leading to increased flows in many local rivers and streams. An additional 30 to 40 millimetres of rain is forecasted to arrive by Thursday. Due to the saturated ground, Environment Canada has also issued a yellow warning for the Kitchener, Cambridge, and Waterloo area, indicating a moderate risk of impact.
While officials are not anticipating any major flooding at this time, they are closely monitoring conditions. The conservation authority uses dozens of automatic water level gauges to track flows in real-time, and they are actively managing their seven major reservoirs to help reduce the risk of flooding downstream. These reservoirs are currently at their normal operating levels for this time of year.
This follows an active spring season that has already seen multiple flood messages issued throughout March due to rapid snowmelt and heavy rains. Residents are encouraged to stay away from riverbanks and low-lying areas while water levels remain high.
