The Grand River Conservation Authority has ended the flood warning for communities across the Grand River watershed, including Kitchener, Cambridge, St. Jacobs, and West Montrose, as water levels begin to slowly recede.

While the immediate threat of flooding has eased, a flood watch remains in place for the entire watershed until 12 p.m. on Tuesday, April 7, 2026. This region, which spans approximately 7,000 square kilometres from Dundalk to Lake Erie, saw up to 70 mm of rainfall from recent thunderstorms and warm temperatures, leaving the ground saturated.

Although water levels and flows are gradually declining, they remain above normal. The conservation authority is continuing to manage the situation by using its major reservoirs—including those at Belwood, Conestogo, Guelph, Luther, Woolwich, Laurel, and Shade’s Mills—to help reduce the impact of potential downstream flooding.

Residents are encouraged to remain cautious, as further rain is expected. Forecasts from Environment Canada indicated an additional 15 to 25 mm of rainfall could arrive on Saturday, April 4, 2026. Because the ground is already saturated, this additional precipitation could increase runoff and raise the risk of flooding in low-lying areas that are typically prone to high water.
